20 Position Receptacle Connector 0.100" (2.54mm) Through Hole Tin The SSQ-110-03-T-D is a through-hole dual-row socket strip receptacle connector manufactured by Samtec, designed for board-to-board and pin header mating applications using the industry-standard pitch spacing that has been dominant in through-hole PCB interconnect design for decades. It belongs to Samtec's SSQ series, a family of square-post socket strip connectors that accept standard square-pin headers and are widely used across prototyping, instrumentation, test and measurement, embedded systems, industrial control, and general-purpose PCB stacking applications. As a socket strip of the receptacle gender, the SSQ-110-03-T-D is intended to receive a mating male pin header, creating a reliable and separable board-to-board or wire-to-board connection. The dual-row configuration provides a higher contact density within a given board length than a single-row socket, which is why dual-row socket strips in this pitch class are extensively used in applications such as microcontroller and single-board computer expansion connectors, module-to-baseboard interfaces, and other designs where a significant number of signal, power, or ground connections must be made across a single separable connector interface. The connector features square solder tails for through-hole PCB mounting, with the "-T" suffix in the part number designating the square post tail style, which provides a well-defined mechanical footprint and reliable solder joint formation in wave solder and hand-solder assembly processes. The "-D" suffix indicates the dual-row configuration. Contact material is phosphor bronze, a widely used spring-contact alloy chosen for its combination of good electrical conductivity, excellent spring properties that maintain consistent contact force across many mating cycles, and resistance to stress relaxation over time. The contacts are finished with matte tin plating over nickel underplate, providing a solderable, cost-effective contact surface suitable for the majority of general-purpose signal and low-power applications for which this connector class is typically used. The insulator body is molded from black liquid crystal polymer, a high-performance engineering thermoplastic that offers the high dimensional stability, excellent electrical insulation properties, and high-temperature resistance needed to withstand wave soldering and reflow-adjacent thermal exposure during PCB assembly. The material also carries a UL94 V-0 flammability rating, reflecting its self-extinguishing behavior in the event of an ignition source, which is required or preferred in many end-product regulatory compliance frameworks. The SSQ series is widely used in conjunction with Samtec's TSW series male pin headers as a complementary mating pair, and the connector is compatible with a broad range of standard square-pin headers from other manufacturers that conform to the same pitch and pin geometry, making it a versatile choice for general-purpose through-hole header applications.

SDRAM Memory IC 512Mbit Parallel 143 MHz 5.4 ns 54-TSOP II The AS4C32M16SB-7TCN is a single-data-rate synchronous dynamic random-access memory (SDR SDRAM) device manufactured by Alliance Memory. It is organized internally as a multi-bank array, allowing concurrent access operations across banks to improve effective memory bandwidth compared to simpler asynchronous DRAM architectures. The device is intended for general-purpose embedded memory applications where a synchronous, clock-driven memory interface is required, including embedded systems, industrial controllers, consumer electronics, networking equipment, and other designs that rely on a parallel SDRAM interface for working memory or buffering. As a drop-in style component within Alliance Memory's broader memory portfolio, this part is designed to be pin- and function-compatible with legacy SDR SDRAM devices originally offered by other manufacturers, allowing designers to source a continued-availability alternative for designs that depend on this memory architecture even as some original suppliers have discontinued production. This makes the device particularly useful in long-lifecycle industrial, embedded, and legacy system designs where a guaranteed supply of a specific memory interface and timing profile is critical to sustaining production over many years. The "B" designation in the part family indicates a specific die revision within the AS4C32M16S product line, reflecting a particular generation of internal silicon design while maintaining functional and pinout compatibility with related die revisions in the same footprint. The device communicates over a standard synchronous SDRAM command interface, using a clock-synchronized protocol for row and column addressing, data burst transfers, and bank management, and it supports the auto-refresh and self-refresh mechanisms typical of SDRAM devices to maintain stored data integrity without requiring constant external refresh management by the host controller. Mechanically, the device is housed in a thin small-outline package suited to space-constrained PCB layouts, and it is built for standard surface-mount assembly processes. The "-7TCN" suffix on this part number reflects a specific speed grade, package style, and temperature grade combination within the product family, with this particular variant intended for commercial temperature range operation. The device is supplied in tray packaging for surface-mount assembly and is compliant with RoHS material restrictions, supporting standard environmental and regulatory requirements for electronic components.

100 Position Connector Receptacle, Center Strip Contacts Surface Mount Gold The DF40C-100DS-0.4V(51) is a board-to-board and board-to-FPC receptacle connector manufactured by Hirose Electric. It belongs to the DF40 series, a family of fine-pitch stacking connectors intended for compact, high-density interconnect applications such as mobile devices, cameras, wearables, and other space-constrained electronics. The connector functions as the receptacle (socket) half of a mating pair, designed to stack with a corresponding DF40 plug header to join two printed circuit boards, or a printed circuit board and a flexible printed circuit, in a low-profile vertical arrangement. This particular part number represents the full-position, low-profile variant within the series, configured without a reinforcing metal fitting and without a locating boss or mechanical holddown feature, meaning it relies on the contact array itself rather than additional structural hardware for mechanical retention during reflow and handling. The connector is supplied in straight, surface-mount form and is non-polarized, so it can be inserted in either orientation relative to its mating counterpart. Contacts are arranged in parallel rows along the connector body, with gold plating in the contact mating area to ensure reliable signal continuity and resistance to oxidation over repeated use. The series is positioned by Hirose as a general-purpose, high-speed-capable interconnect, suitable for a range of differential and single-ended signaling standards used in consumer and industrial electronics, with the broader DF40 family supporting interfaces such as USB, MIPI, SATA, and PCIe. Its low stacking height and fine contact pitch make it well suited to applications where board-to-board spacing must be minimized, such as camera modules, display modules, or stacked daughterboard architectures in handheld and wearable products. The connector is packaged on embossed carrier tape for automated pick-and-place assembly, and its construction is compliant with RoHS material restrictions. Mechanically, the connector body is built to support repeated mating cycles typical of consumer electronics assembly and rework, while maintaining stable electrical contact under vibration and thermal cycling across its rated environmental range. As a stacking-style connector rather than a card-edge or cable-mount type, it is intended to be soldered directly to a host PCB pad pattern, with the mating plug soldered to the corresponding board or FPC, allowing the two assemblies to be joined and separated as needed during manufacturing, test, or service operations.
