M20-9952145

Headers, Male Pins Overview

The M20-9952145 is a horizontal pin header connector from the Harwin M20 series, designed for board-to-board or cable applications. It features 42 positions arranged in a dual inline (DIL) configuration with two rows of 21 contacts each. The connector utilizes a 0.100-inch (2.54mm) pitch and is intended for through-hole mounting. Contacts are made of brass with gold plating to ensure reliable signal transmission. The unit supports a rated current of 3A per contact and operates within a temperature range of -40°C to +105°C.

Headers, Male Pins Feature Summary

• Horizontal orientation design facilitates compact circuit board layouts
• Dual inline structure provides high-density connectivity options
• Gold-plated brass contacts ensure durable electrical performance

Headers, Male Pins Applications

• Board-to-board interconnections
• Cable-to-board assemblies

Headers, Male Pins Procurement Notes

Verify the specific part number against official Harwin documentation to confirm the horizontal orientation and DIL configuration. Ensure that the through-hole mounting style matches the target PCB footprint requirements. Confirm that the 3A current rating and operating temperature range meet the system's thermal and electrical specifications before finalizing procurement.

Headers, Male Pins Selection Notes

Select this component when a horizontal connection is required to save vertical space on the assembly. The dual inline format allows for increased pin counts without expanding the board area significantly. Verify compatibility with mating sockets or cables that match the 2.54mm pitch and square contact shape.

Headers, Male Pins Part Context

This component belongs to the M20 series, which offers various configurations including vertical and angled headers. The M20-9952145 specifically addresses needs for horizontal routing in dense electronics. It shares common material properties like PA6T insulation and UL94 V-0 flammability ratings with other parts in the family.

Headers, Male Pins Replacement Considerations

Direct substitutes must maintain the 42-position count, dual inline layout, and horizontal mounting style. Verify that any alternative part matches the 2.54mm pitch and through-hole termination method to ensure mechanical and electrical compatibility.
