M20-9753942

Headers, Male Pins Overview

The M20-9753942 is a single-row vertical pin header assembly from the Harwin M20 series, designed for surface mount technology. It features a 2.54 mm (0.1 inch) pitch and provides 39 positions for reliable interconnection. The connector utilizes brass contacts with tin plating to ensure conductivity and corrosion resistance. Constructed with a black nylon housing, it supports through-hole solder termination. This component is rated for 3 A current and 750 V voltage, operating within a temperature range of -40°C to +105°C. It serves as a standard board-to-board or wire-to-board interface solution.

Headers, Male Pins Feature Summary

• Single row vertical configuration for compact PCB layout
• Tin-plated brass contacts for durable electrical connection
• Nylon housing material providing thermal stability

Headers, Male Pins Applications

• Board-to-board interconnection in electronic assemblies
• Wire-to-board connections requiring vertical orientation
• General purpose signal and power distribution on PCBs

Headers, Male Pins Procurement Notes

Verify the specific contact plating and housing color against official datasheets, as tin-plated variants may differ visually from gold-plated counterparts. Confirm the 39-position count matches design requirements. Check RoHS compliance status directly from manufacturer documentation before integration. Ensure surface mount footprint compatibility with existing PCB silkscreen and copper patterns.

Headers, Male Pins Selection Notes

Choose this part when a single-row, high-density vertical header is required for surface mount applications. The 2.54 mm pitch ensures compatibility with standard ribbon cables and mating headers. Tin plating offers cost-effective performance for non-critical environments, while the nylon housing provides mechanical robustness. Consider the 3 A rating for current carrying capacity needs.

Headers, Male Pins Part Context

This component belongs to the Harwin M20 series, a widely used line of connectors known for reliability and precision engineering. The M20 series encompasses various configurations including pin headers, receptacles, and wire housings. The M20-9753942 specifically represents a high-pin-count variant suitable for complex circuit boards requiring numerous vertical interconnect points.

Headers, Male Pins Replacement Considerations

M20-9754042 is a similar 40-position header but differs in position count and potentially plating. Verify exact pin count and termination style before substitution. No direct identical substitute is confirmed in public data; custom fabrication or redesign may be necessary if exact match is unavailable.
