Overview
The M20-7870746P is a dual-row socket assembly from the Harwin M20 series, designed for surface-mount technology. It features a bottom entry configuration with 14 positions arranged in two rows of seven. The connector utilizes a 2.54 mm (0.1 inch) pitch and employs solder termination for PCB attachment. The contacts are tin-plated to ensure reliable conductivity and corrosion resistance.
Feature Summary
- Dual-row design optimized for high-density board-to-board connections
- Surface-mount construction facilitates automated assembly processes
- Bottom entry contact orientation allows for compact vertical integration
Applications
- High-density electronic assemblies requiring space-efficient interconnects
- Board-to-board stacking applications in compact devices
- Industrial control modules utilizing surface-mount manufacturing
Procurement Notes
Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance documentation matches current regulatory requirements. Validate pin count and plating specifications against project schematics prior to procurement. Ensure storage conditions maintain contact integrity given the component's age.
Selection Notes
Select this component when a low-profile, dual-row SMT socket is required for 14-position connectivity. The 2.54 mm pitch ensures compatibility with standard header pins. Consider the bottom entry style for applications where top-side clearance is limited. Verify that the tin plating meets environmental constraints for the specific deployment.
Part Context
This part belongs to the M20 series, which offers industrial-standard connectors for demanding environments. The series provides various configurations including through-hole and surface-mount options. The M20-7870746P specifically addresses needs for robust, double-row interconnects in space-constrained designs.
Replacement Considerations
The datasheet indicates this part is obsolete. Review the official obsolescence notification for recommended substitute part numbers. Cross-reference compatible headers within the same M20 family to ensure mechanical and electrical continuity.
