M20-9990346

Headers, Male Pins Overview

The M20-9990346 is a single-row, vertical pin header assembly from the Harwin M20 series. It features a 2.54 mm pitch and three positions with male pin contacts. The connector supports board-to-board and wire-to-board systems via through-hole solder termination. Rated for 500 V and 3 A per contact, it operates within a temperature range of -40°C to +105°C. The housing is constructed from black nylon with UL94 V-0 flammability rating. Contact plating is tin over brass, ensuring reliable electrical performance in standard industrial environments.

Headers, Male Pins Feature Summary

• Vertical straight orientation for direct PCB mounting
• Single row configuration with cuttable strip design
• Tin-plated brass contacts for corrosion resistance
• Nylon insulation housing with high thermal stability

Headers, Male Pins Applications

• General-purpose board-to-board interconnections
• Wire-to-board signal routing
• Industrial control panel assemblies
• Consumer electronics internal connections

Headers, Male Pins Procurement Notes

Verify the specific contact plating finish upon ordering, as datasheet references may vary between tin and gold options for this part number. Confirm that the required mating height aligns with the 6.1 mm specification. Ensure the selected variant matches the intended voltage rating of 500 V for safety compliance. Cross-reference the manufacturer's latest documentation to confirm current production status and availability before finalizing procurement plans.

Headers, Male Pins Selection Notes

Select this component when a low-profile, single-row connection is required for 2.54 mm pitch applications. The vertical design facilitates dense PCB layouts while maintaining mechanical stability. Consider the tin plating for cost-effective solutions where high-cycle mating is not required. Evaluate the 3 A current rating against the total system load requirements to ensure adequate thermal management during operation.
