M22-2412046

Headers, Male Pins Overview

The Harwin M22-2412046 is a male pin header from the M22 series, featuring a 20+20 position configuration with a 2.00 mm pitch. It utilizes a two-row arrangement with a 2.00 mm row spacing and is designed for right-angle through-hole soldering. The contacts are tin-plated copper alloy pins rated for 2 A current and 500 V voltage. The housing is black nylon (PA6T) with UL94 V-0 flammability rating. This component is currently obsolete.

Headers, Male Pins Feature Summary

• Right-angle through-hole mounting for board-to-board or cable connections
• Tin-plated copper alloy male pins ensuring reliable conductivity
• Black PA6T nylon insulation providing UL94 V-0 flame resistance

Headers, Male Pins Applications

• Board-to-board interconnects in industrial control systems
• Cable assembly connections in automotive electronics
• General-purpose signal routing in consumer electronic devices

Headers, Male Pins Procurement Notes

This component is officially listed as obsolete and no longer manufactured by Harwin Inc. Verification of availability should focus on surplus distributors or secondary market sources rather than direct manufacturer channels. Buyers must confirm the authenticity and physical condition of existing stock, as lead times and pricing are subject to third-party seller variability. Cross-referencing datasheets is essential to ensure compatibility with replacement strategies.

Headers, Male Pins Selection Notes

Engineers selecting this part should verify that the 2.00 mm pitch and 40-position count match the PCB footprint requirements. The right-angle orientation and through-hole termination method must align with the assembly process. Since the part is obsolete, alternative selection should prioritize components with identical mechanical dimensions, electrical ratings, and contact plating specifications to maintain design integrity without re-spinning the board.

Headers, Male Pins Part Context

The M22-2412046 belongs to Harwin’s M22 series of high-density headers, known for their compact 2.00 mm pitch and robust construction. This specific model represents a 40-pin variant designed for applications requiring dense signal routing in limited space. The series typically features push-pull locking mechanisms and is widely used in sectors demanding reliable connectivity under varying environmental conditions.

Headers, Male Pins Replacement Considerations

Harwin lists M22-2042005 as a potential substitute. This alternative is a horizontal gold-plated header with the same 20+20 position count and 2.00 mm pitch. Engineers must verify that the change from right-angle to horizontal orientation and tin to gold plating does not impact mechanical fit or electrical performance in the target application.
