687860054

Overview

The Molex 687860054 is a 2-position, single-row, vertical through-hole header connector from the KK® 1.27mm (0.050 inch) Wire-to-Board series. It features a 1.27mm pitch and is designed for PCB mounting with a 3.96mm mating height. The housing is constructed from black polyamide 6/6 material, rated UL 94V-0, and includes a polarizing keying feature on the housing to ensure correct orientation during assembly. The connector supports wire sizes ranging from 28 AWG to 22 AWG and offers a current rating of 1.5A per contact.

Feature Summary

• Vertical through-hole design for direct PCB integration
• Polarized housing to prevent incorrect mating
• Compact 1.27mm pitch for high-density applications

Applications

• Consumer electronics internal connections
• Industrial control boards
• Telecommunications equipment

Procurement Notes

Verify the specific suffix code against the manufacturer's latest datasheet to confirm plating type and packaging format. Ensure compatibility with mating receptacles from the same KK 1.27mm series. Confirm that the selected variant meets the required environmental ratings for your specific application environment.

Selection Notes

Select this component when a low-profile, vertical interconnect solution is required for small gauge wires. Consider the 1.27mm pitch constraint and verify that the PCB footprint matches the specified terminal dimensions. Evaluate the need for polarizing keys if multiple orientations are possible in the assembly process.

Part Context

This part belongs to the extensive KK 1.27mm family, known for its versatility in board-to-board and wire-to-board connections. The series offers various row counts, heights, and termination styles, making it a standard choice for general-purpose electronic assemblies requiring reliable signal and power transmission in compact spaces.

Replacement Considerations

Direct replacements must match the 1.27mm pitch, 2-position count, and vertical through-hole termination. Verify housing color and UL recognition status. Cross-referencing with other manufacturers requires careful dimensional analysis of the terminal cavity and PCB hole pattern.

FAQ
