The component is suitable for industrial control systems, automation equipment, power interfaces, instrumentation, building controls, and general electronic hardware assemblies. ## Device Identification Manufacturer Part Number: **1726202** Manufacturer: **Phoenix Contact** Product Name: **MKKDSN 1,5/ 8-5,08** Product Family: **MKKDSN 1,5** Product Line: **COMBICON Terminals** Device Category: **Connector and Interconnect Component** Device Type: **PCB Terminal Block** Connection Type: **Wire-to-Board Terminal Block** Termination Method: **Screw Connection with Tension Sleeve** Mounting Type: **Through-Hole PCB Mount** ## Functional Description The device functions as a fixed printed circuit board terminal block that allows external conductors to be connected directly to PCB circuits. The screw-clamp connection secures the conductor mechanically while maintaining electrical continuity through the terminal body and solder pins. This makes the component suitable for wiring interfaces that require durability, accessibility, and field-service capability. ## Mechanical Description The terminal block uses a compact green housing with a two-row terminal arrangement and side-access conductor entry. Its layout supports dense wiring connection on a printed circuit board while maintaining practical access for conductor insertion and screw tightening. The through-hole solder pins provide mechanical stability and electrical connection to the host PCB. ## Electrical Description The component is intended for low-voltage power and signal connection applications within the manufacturer’s specified current and voltage ratings. It supports conductor connection for typical industrial and control wiring requirements when used with compatible wire sizes, correct strip length, and proper tightening torque. ## Material and Contact Description The terminal block uses an insulating housing with internal conductive contact elements designed to transfer current from the inserted conductor to the PCB solder connection. The screw connection with tension sleeve helps maintain stable contact pressure and reliable conductor retention during normal operating conditions. ## Mounting and Assembly Description The **1726202** is intended for through-hole PCB soldering, including wave-solder assembly processes. The PCB layout should follow the manufacturer’s recommended hole size, pad pattern, spacing, and soldering guidelines. The component should be positioned to allow safe conductor insertion, screwdriver access, and adequate clearance from nearby parts or enclosure walls. ## Application Suitability The device is suitable for industrial control boards, automation modules, relay boards, power supply interfaces, building automation equipment, instrumentation systems, sensor wiring interfaces, signal distribution boards, and other electronic products requiring secure PCB wire termination. ## Design Considerations The design should account for conductor size compatibility, current carrying requirement, voltage rating, creepage and clearance spacing, tightening torque, solder joint strength, wire routing, and user access during installation or maintenance. The terminal block should not be used beyond the manufacturer’s specified electrical, thermal, or mechanical limits. ## Hashtags #commonpartslibrary #terminalblock #pcbterminalblock #phoenixcontact #mkkdsn #mkkdsnterminalblock #combicon #wiretoboard #screwterminal #fixedterminalblock #throughholecomponent #wavesoldering #soldermount #connector #interconnect #fieldwiring #industrialelectronics #automationequipment #controlsystems #powerinterface #pcbdesign #hardwaredesign #electronicscomponents #electronicparts #engineeringparts #componentlibrary #electronicsengineering

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.
