Overview
The Harwin M20-7860346P is a single-row, surface-mount female receptacle connector from the M20 series. It features a 2.54 mm (0.1 inch) pitch and three positions. Designed for board-to-board applications, it supports dual entry for both top and bottom mounting orientations. The contacts are tin-plated phosphor bronze, rated for 3A current at 105°C. The housing is black UL94 V-0 rated polyamide. This component utilizes a push-pull locking mechanism to ensure secure mating.
Feature Summary
- Dual-entry design compatible with top or bottom board insertion
- Push-pull locking mechanism for secure connection retention
- Surface-mount termination for automated PCB assembly
Applications
- Board-to-board interconnects in embedded systems
- High-density electronic assemblies requiring vertical stacking
- Consumer electronics with space-constrained layouts
Procurement Notes
Verify the 'P' suffix against official Harwin documentation to confirm specific packaging or tape-and-reel specifications. Ensure compatibility with standard SMT reflow profiles. Cross-reference the part number with the latest RoHS compliance certificates. Confirm that the tin plating meets the required environmental resistance standards for the intended application environment.
Selection Notes
Select this component when a low-profile, surface-mount female header is required for single-row connections. The dual-entry feature offers flexibility in mechanical design compared to fixed-orientation connectors. Consider the 3A current rating and 105°C temperature limit for thermal management. The push-pull lock is suitable for applications requiring vibration resistance without screws.
Part Context
This part belongs to the Harwin M20 series, which provides industrial-standard rectangular connectors. The series includes various row counts, pitches, and mounting styles. The M20-7860346P specifically addresses the need for compact, high-reliability surface-mount interfaces in modern electronics manufacturing.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided data. Consult Harwin engineering for direct replacements if this specific variant is discontinued.
