M22-2581005

Headers, Male Pins Overview

The M22-2581005 is a vertical pin header connector from the Harwin M22 series, designed for through-hole mounting. It features a 20-position configuration with two rows and a 2.00mm (0.079 inch) pitch. The connector utilizes phosphor bronze contacts with gold plating for reliable signal transmission. Constructed with black polyamide (PA6T) insulation rated UL94 V-0, it supports a working temperature range of -40°C to 105°C. Each contact is rated for 1A current. The design includes a push-pull locking mechanism and square contact shapes, suitable for board-to-board or cable applications.

• Gold-plated phosphor bronze contacts for durability
• Push-pull locking style for secure mating
• UL94 V-0 rated black PA6T insulation

Headers, Male Pins Applications

• Board-to-board interconnections
• Cable-to-board connections
• General electronic equipment internal wiring
• Industrial control modules

Headers, Male Pins Procurement Notes

Verify the specific ordering suffix against the official Harwin datasheet to ensure correct pin count, row configuration, and termination type. Confirm that the required contact material and plating thickness meet the application's electrical performance standards. Check for RoHS compliance status if environmental regulations apply. Ensure the selected variant matches the intended PCB layout dimensions and mounting orientation requirements.

Headers, Male Pins Selection Notes

Select this component when a vertical, non-shrouded header with a 2.00mm pitch is required for through-hole assembly. Consider the 1A per contact current rating and the -40°C to 105°C operating temperature range for suitability. Evaluate the need for the push-pull locking feature versus other retention methods. Compare physical dimensions and insulation height against available board space constraints.

Headers, Male Pins Part Context

This part belongs to the M22 series of rectangular connectors by Harwin Inc., which are characterized by their 2.00mm pitch and robust construction. The series offers various configurations including shrouded and unshrouded options, different row counts, and both surface mount and through-hole terminations. The M22-2581005 specifically represents a standard vertical pin header variant within this widely used industrial connector family.

Headers, Male Pins Replacement Considerations

Direct substitutes may include other Harwin M22 series headers with identical 20-position, 2-row, 2.00mm pitch specifications. Verify mechanical compatibility such as housing height and pin length before substitution. Alternative manufacturers offering 2.00mm pitch through-hole headers should be evaluated for pinout alignment and locking mechanism differences.
