Overview
The M20-7871346P is a Harwin M20 series socket assembly featuring 26 positions arranged in a dual-in-line (DIL) configuration with two rows. It utilizes a 2.54 mm pitch and 2.54 mm row spacing for board-to-board connectivity. The component employs female socket contacts with tin plating and incorporates a push-pull fastening mechanism. Designed for surface-mount technology, it offers bottom entry access to ensure secure mating engagement.
Feature Summary
- Push-pull fastening mechanism for reliable connection retention
- Surface-mount construction with bottom entry design
- Tin-plated female socket contacts for signal integrity
Applications
- Board-to-board interconnects in embedded systems
- High-density electronic assemblies requiring secure retention
- Industrial control modules and communication equipment
Procurement Notes
Verify the exact suffix 'P' against official datasheets to confirm the presence of the push-pull feature, as standard M20 variants may lack this mechanism. Confirm RoHS compliance status through current manufacturer documentation. Ensure compatibility with SMT reflow profiles specified in the technical data sheet before integration into production workflows.
Selection Notes
Select this variant specifically when mechanical retention via push-pull latching is required rather than friction fit. Verify that the PCB footprint supports the specific SMT pad layout for the M20 DIL series. Consider the 26-position capacity and dual-row geometry to ensure adequate space allocation on the target circuit board design.
Part Context
This component belongs to the Harwin M20 series, which provides industrial-standard headers and wire housings. The series is characterized by compact designs suitable for high-density PCB applications. The M20 line typically includes both through-hole and surface-mount options with varying contact counts and plating configurations.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Cross-reference with other Harwin M20 series sockets only if the push-pull feature is not critical.
