Overview
The M20-8760546R is a surface mount pin header from the Harwin M20 series, designed for board-to-board or cable connections. It features a 2.54 mm (0.100 inch) pitch with 10 positions arranged in a dual-row configuration. The connector utilizes brass contacts with gold plating on the mating interface and tin plating on the tail for soldering. Rated at 3A per contact and 250V, it operates within a temperature range of -40°C to 105°C. The housing is made of black PA6T nylon with UL94 V-0 flammability rating.
Feature Summary
- Surface mount installation with bottom entry design for automated pick-and-place assembly
- Gold-plated mating contacts ensure reliable signal transmission and corrosion resistance
- Dual-row layout provides compact connectivity with standard 2.54mm spacing
Applications
- Board-to-board interconnections in compact electronic modules
- Cable-to-board connections requiring surface mount termination
- High-density circuit boards where space efficiency is critical
Procurement Notes
Verify that the suffix 'R' corresponds to the specific reel packaging and bottom-entry variant as documented. Confirm the gold plating specification matches the application requirements. Ensure the surface mount footprint aligns with the PCB design guidelines provided in the official datasheet before finalizing procurement orders.
Selection Notes
Select this component when surface mount technology is required for dual-row headers. The gold-plated contacts are suitable for applications demanding high reliability and low contact resistance. The bottom-entry design facilitates efficient SMT placement processes compared to top-entry alternatives.
Part Context
This part belongs to the Harwin M20 series, which offers a range of vertical and right-angle connectors. The M20-8760546R specifically addresses the need for surface mount solutions within this family, providing a robust alternative to through-hole variants while maintaining the standard 2.54mm pitch compatibility.
Replacement Considerations
M20-8760546 is the through-hole equivalent. M20-8760542 is a similar SMT header but may differ in contact plating or packaging. Verify mechanical dimensions and electrical ratings against these alternatives.
