M50-3551042

Headers, Male Pins Overview

The Harwin M50-3551042 is a male dual in-line (DIL) pin header connector from the Archer M50 series. It features a 20-position configuration with a 1.27 mm pitch across two rows. Designed for through-hole mounting, this straight-angle connector utilizes solder termination for secure PCB attachment. The contacts are constructed from brass and finished with gold plating to ensure reliable conductivity. The housing is made of thermoplastic material rated UL94 V-0 for flammability. It operates within a temperature range of -40°C to +105°C and supports a current rating of 1A per contact.

Headers, Male Pins Feature Summary

• Unshrouded design facilitates easy access for mating connections
• Integrated ejector header mechanism simplifies board removal
• Straight top-entry orientation optimizes vertical space utilization
• Gold-plated brass contacts provide durable electrical performance

Headers, Male Pins Applications

• General purpose electronic interconnects
• Medical device circuitry
• Telecommunications equipment

Headers, Male Pins Procurement Notes

Verify the specific suffix and packaging format when ordering, as availability may vary between tubes and reels. Confirm that the unshrouded style aligns with your assembly requirements. Ensure compatibility with mating sockets from the same M50 series family. Check for RoHS compliance status at the time of purchase. Validate mechanical dimensions against your PCB footprint specifications before finalizing procurement.

Headers, Male Pins Selection Notes

Select this component when a low-profile, unshrouded male header is required for through-hole applications. The 1.27 mm pitch suits dense circuit layouts. Consider the ejector feature if frequent board replacement is anticipated. Verify that the straight angle fits within your enclosure height constraints. Ensure the 1A current rating meets your circuit demands.

Headers, Male Pins Part Context

This part belongs to the Harwin Archer M50 series, which offers various configurations including shrouded and unshrouded options. The series supports both surface mount and through-hole technologies. The M50-3551042 specifically addresses needs for accessible, high-density connections in constrained spaces. It complements other M50 series components like jumper sockets and shunts.

Headers, Male Pins Replacement Considerations

Compatible substitutes include other Harwin M50 series male headers with identical 20-position, 1.27 mm pitch, and through-hole specifications. Ensure any alternative maintains the same current rating and temperature range. Verify mechanical compatibility regarding pin length and row spacing.
