Headers, Receptacles, Female Sockets Procurement Notes

This component has reached End-of-Life status and is no longer manufactured by Harwin Inc. Procurement must focus on identifying verified replacement part numbers from the same product family or compatible alternatives. Verify that substitute connectors match the original pin count, pitch, and mounting style to ensure mechanical and electrical compatibility without redesigning the host circuit board.

Headers, Receptacles, Female Sockets Selection Notes

Engineers selecting this component should prioritize exact dimensional matching due to the specific vertical SMT footprint. The dual-row layout requires careful consideration of mating height and clearance constraints. Since the part is obsolete, selection must involve validating that any replacement maintains the same 1.27mm pitch and 38-position configuration to preserve existing harness and PCB layouts.

Headers, Receptacles, Female Sockets Part Context

Part of the Archer M50 series, known for compact 1.27mm spacing and high reliability. This specific model represents a legacy vertical socket variant intended for applications where space efficiency and secure surface-mount attachment were critical design requirements.

Headers, Receptacles, Female Sockets Replacement Considerations

Verify cross-reference availability through official distributor channels. Ensure substitutes maintain identical 19+19 positioning and vertical orientation.
