M50-4302945

Headers, Receptacles, Female Sockets Overview

The Harwin M50-4302945 is a surface-mount board-to-board receptacle from the Archer M50 series. It features a dual-row configuration with 29+29 positions, totaling 58 contacts. The connector utilizes a 1.27mm pitch and a 1.27mm row spacing to facilitate high-density interconnections. Designed for vertical SMT installation, it employs gold-plated phosphor bronze sockets housed in black liquid crystal polymer (LCP). The unit operates within a temperature range of -40°C to +105°C and carries an MSL rating of Level 1.

Headers, Receptacles, Female Sockets Procurement Notes

Verify component authenticity by cross-referencing the manufacturer's official datasheet specifications against the physical product markings. Confirm that the part number suffix matches the exact pin count and termination style required for your design. Ensure storage conditions comply with moisture sensitivity level guidelines to maintain solderability prior to reflow.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when a compact, high-pin-count solution is required for vertical mating applications. The 1.27mm pitch allows for significant I/O density within a small footprint. Verify that the PCB layout supports the specific row spacing and that the mating header aligns with the dual-row socket geometry for proper engagement.

Headers, Receptacles, Female Sockets Part Context

This component belongs to the Harwin Archer M50 family, which specializes in high-performance board-to-board connections. The series is characterized by its robust construction and suitability for demanding environments. The M50-430xx45 designation specifically identifies the vertical SMT socket variant within this extensive lineup of interconnect solutions.

Headers, Receptacles, Female Sockets Replacement Considerations

Direct substitutes include other Harwin M50 series sockets with identical 58-position counts and 1.27mm pitch. Verify mechanical dimensions and contact plating before substitution. Generic equivalents may lack the specific LCP material properties or precise alignment features of the original design.
