M22-5321405

Headers, Male Pins Overview

The Harwin M22-5321405 is a surface mount header connector featuring 28 positions arranged in a dual in-line configuration. It utilizes a 2.00mm (0.079 inch) pitch for compact board-to-board interconnections. The component employs gold-plated phosphor bronze contacts housed within a black polyamide insulation body rated UL94 V-0. Designed for through-hole termination, it supports a continuous current rating of 1A per contact and operates reliably within a temperature range of -40°C to +105°C.

Headers, Male Pins Feature Summary

• Dual in-line surface mount design for high-density PCB integration
• Gold-plated phosphor bronze contacts ensure reliable electrical performance
• UL94 V-0 rated polyamide insulation provides thermal stability

Headers, Male Pins Applications

• Compact electronic assemblies requiring board-to-board connections
• Embedded PC systems and motherboard interfaces
• Industrial monitoring and control devices

Headers, Male Pins Procurement Notes

Verify the specific suffix codes against the manufacturer datasheet to confirm exact pin count and orientation. Ensure surface mount footprint compatibility with PCB fabrication capabilities. Confirm RoHS compliance status if required by project specifications. Cross-reference the DigiKey part number ending in ND for accurate sourcing channels.

Headers, Male Pins Selection Notes

Select this component when space constraints necessitate a low-profile surface mount solution. The 2.00mm pitch offers a balance between signal density and manufacturing tolerance. Consider the 1A current rating for power distribution needs. Verify that the dual-row layout aligns with the mating connector's mechanical interface requirements.

Headers, Male Pins Part Context

This part belongs to the Harwin M22 series, which establishes an industrial standard for 2mm pitch connectors. The series includes various configurations such as vertical headers, right-angle sockets, and surface mount options. These components are widely adopted in consumer electronics and communication equipment due to their robust mechanical design and consistent electrical characteristics.

Headers, Male Pins Replacement Considerations

Direct substitutes include other Harwin M22 series surface mount headers with identical 28-position counts and 2.00mm pitch. Verify mechanical footprint dimensions and terminal plating specifications before substitution. Alternative manufacturers may offer compatible parts but require rigorous validation of mating interface tolerances.
