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.
