M20-7860346

Overview

The M20-7860346 is a 3-position receptacle from the Harwin M20 series, designed for board-to-board interconnections. It features a 2.54 mm (0.100 inch) pitch and utilizes surface mount termination. The connector supports both bottom and top entry configurations. Contacts are finished with tin plating to ensure reliable signal transmission. The housing is constructed from black insulating material rated UL94 V-0 for flame resistance. It operates within a temperature range of -40°C to 105°C.

Feature Summary

• Supports flexible bottom or top entry mating orientations for versatile PCB layout integration
• Utilizes push-pull locking mechanism to secure connections during operation
• Features durable tin-plated contacts for consistent electrical performance
• Constructed with high-temperature resistant UL94 V-0 rated insulation

Applications

• Embedded PC systems
• Motherboard interconnects
• Consumer electronics assemblies
• Industrial monitoring equipment

Procurement Notes

Verify the specific contact plating finish and entry orientation requirements against the official datasheet before ordering. Confirm that the surface mount footprint matches the target PCB design. Check current product lifecycle status as manufacturing availability may vary. Ensure compliance with RoHS directives if required by the end application. Cross-reference the manufacturer part number to avoid confusion with similar M20 series variants.

Selection Notes

Choose this component when a low-profile, surface-mount female header is required for dense board-to-board connections. The 2.54 mm pitch is standard for general-purpose electronic interfaces. Consider the push-pull retention feature if vibration resistance is necessary. Evaluate the thermal limits to ensure suitability for the operating environment. Compare physical dimensions against space constraints on the host circuit board.

Part Context

This part belongs to the M20 series, which provides industrial-standard rectangular connectors. The series offers various row counts and termination styles including through-hole and surface mount options. These connectors are widely adopted in embedded computing and communication devices due to their compact form factor and reliability. The M20 line emphasizes high-density packaging capabilities for modern electronic systems.

Replacement Considerations

M20-7860342 is listed as a potential substitute in distributor records. Verify pin count, pitch, and mounting style compatibility before substitution. Ensure the alternative part meets the same electrical and mechanical specifications.
