M20-9703045

Headers, Male Pins Overview

The M20-9703045 is a rectangular connector header from the Harwin M20 series, designed for board-to-board or cable applications. It features a vertical orientation with a 2.54 mm (0.100 inch) pin spacing and accommodates 60 positions in a single row. The connector utilizes through-hole termination for secure PCB mounting. Contact materials consist of brass pins with gold plating to ensure reliable signal transmission. The housing is constructed from black nylon, rated UL94 V-0 for flammability, and supports an operating temperature range of -40°C to +105°C. Rated current is 3A per contact.

Headers, Male Pins Feature Summary

• Vertical pin header design with 2.54mm pitch for standard board-to-board interconnects
• Gold-plated brass contacts housed in UL94 V-0 rated black nylon insulation
• Through-hole termination method ensuring robust mechanical stability on printed circuit boards

Headers, Male Pins Applications

• High-density board-to-board connections in industrial control systems
• Signal routing in telecommunications equipment requiring reliable vertical stacking
• General-purpose electronic assemblies needing standardized 2.54mm spacing headers

Headers, Male Pins Procurement Notes

Verify the specific part number suffix against official Harwin documentation to confirm pin count and orientation. Ensure compatibility with mating socket connectors within the same M20 series family. Check for RoHS compliance status if required by project specifications. Confirm that the vertical height and stack-up dimensions meet the enclosure constraints of the final assembly design before procurement.

Headers, Male Pins Selection Notes

Select this component when a high-pin-count vertical header is required for rigid PCB interconnections. The 60-position configuration suits applications needing extensive signal or power distribution in a compact footprint. Consider the through-hole mounting requirement during layout planning. Evaluate the thermal performance limits of the nylon housing against the operational environment temperatures to ensure long-term reliability under stress conditions.

Headers, Male Pins Part Context

This component belongs to the Harwin M20 series, a widely used line of rectangular connectors known for their versatility and reliability. The series offers various configurations including straight and right-angle headers, as well as wire housings. The M20-9703045 specifically addresses the need for high-density vertical interconnects with standardized spacing, fitting into broader system architectures that utilize 2.54mm pitch interfaces for modular expansion and connection.

Headers, Male Pins Replacement Considerations

Direct substitutes within the Harwin M20 series include M20-9703046 (right-angle variant) or other pin counts like M20-9703042. Cross-manufacturer replacements require matching the 2.54mm pitch, 60-position count, vertical orientation, and through-hole termination style. Verify that alternative suppliers offer comparable gold plating thickness and nylon material ratings to maintain electrical and mechanical performance equivalence.
