M22-2580946

Headers, Male Pins Overview

The Harwin M22-2580946 is a dual in-line (DIL) pin header assembly featuring a 2.00mm pitch and an 18-position configuration arranged in two rows of nine contacts each. Designed for vertical board-to-board interconnection, this component utilizes through-hole termination for secure PCB mounting. The connector system employs square pin sockets with tin plating to ensure reliable signal transmission. It is rated for a maximum voltage of 500V and supports a continuous current of 1A per contact. The housing is constructed from black polyamide (PA6T), providing UL94 V-0 flammability rating and operational stability across a temperature range of -40°C to +105°C.

Headers, Male Pins Feature Summary

• Vertical DIL pin header design for direct board-to-board mating
• Through-hole termination ensures robust mechanical fixation on the PCB
• Tin-plated square pin sockets provide durable electrical connectivity
• Polyamide insulation offers high thermal resistance and flame retardancy

Headers, Male Pins Applications

• High-density electronic module interconnections
• Industrial control system circuit boards
• Automotive electronics assemblies requiring 500V isolation
• Consumer appliance mainboard connections

Headers, Male Pins Procurement Notes

Verify the specific suffix '46' indicates tin plating rather than gold variants when sourcing replacements. Confirm that the 18-position layout matches the target footprint exactly. Ensure the vertical orientation aligns with the assembly height constraints. Cross-reference the PA6T material specification against environmental compliance requirements such as REACH or RoHS standards before finalizing procurement orders.

Headers, Male Pins Selection Notes

Select this model when a vertical 2mm pitch header is required for high-voltage applications up to 500V. The tin-plated contacts are suitable for general-purpose environments where cost-effectiveness is prioritized over extreme corrosion resistance. Consider the 1A current rating per contact to ensure adequate power distribution. Verify that the through-hole installation method fits the manufacturing capabilities of the production line.

Headers, Male Pins Part Context

This component belongs to the Harwin M22 series, a widely used family of rectangular connectors known for their compact form factor and reliability. The M22 series typically features 2.00mm spacing, making it suitable for space-constrained designs. As a DIL header, it pairs with corresponding socket connectors to create stable interconnect solutions for various electronic industries.

Headers, Male Pins Replacement Considerations

M22-2581005 is a similar 20-position variant within the same series but differs in contact count. Ensure the pin count difference does not impact the circuit design. Other M22 headers with identical pitch and row configuration may serve as functional substitutes if pin counts match.
