M22-2581146

Headers, Male Pins Overview

The M22-2581146 is a vertical pin header connector from the Harwin M22 series, designed for board-to-board or cable applications. It features a 22-position configuration with a 2mm (0.079 inch) mating pitch and dual in-line layout. The connector utilizes phosphor bronze contacts with tin plating for reliable signal transmission. Constructed with black polyamide insulation rated UL94 V-0, it supports a working temperature range of -40°C to +105°C. Rated at 1A per contact, this through-hole component offers a robust mechanical solution for high-density interconnect needs.

Headers, Male Pins Procurement Notes

Verify the specific contact plating finish against project requirements, as datasheet references may vary between tin and gold options for similar part numbers. Confirm the exact pin count and row configuration matches the PCB footprint design. Ensure the through-hole soldering process aligns with the specified thermal characteristics of the polyamide material. Cross-reference the manufacturer's latest documentation to confirm current production status and availability timelines before finalizing procurement plans.

Headers, Male Pins Selection Notes

Select this connector when a vertical orientation and 2mm pitch are required for space-constrained designs. The dual-row arrangement maximizes I/O density compared to single-row alternatives. Consider the tin plating option if cost efficiency is prioritized over extended cycle life, while ensuring the 1A current rating meets the circuit load requirements. Verify that the operating temperature range covers the environmental conditions of the intended application zone.

Headers, Male Pins Part Context

This component belongs to the M22 series, a family of connectors known for their slim profile and high reliability. The series offers various configurations including headers, sockets, and shrouded options. The M22-2581146 specifically addresses applications requiring vertical insertion and standard through-hole termination methods, fitting into broader system architectures where modular connectivity is essential.

Headers, Male Pins Replacement Considerations

Direct substitutes include other Harwin M22 series headers with identical 2mm pitch and 22-pin counts, such as M22-2581005 variants with different plating. Ensure replacement parts maintain the same vertical orientation and through-hole mounting style to preserve mechanical compatibility.
