M20-7893842

Overview

The M20-7893842 is a rectangular connector from the Harwin M20 series, classified as a female socket receptacle. It features a dual-row configuration with 38 positions and a standard 2.54 mm (0.100 inch) pin spacing. Designed for through-hole mounting, this component utilizes right-angle termination to facilitate board-to-board or cable connections at a perpendicular orientation. The contacts are constructed from phosphor bronze and feature gold plating on the mating interface to ensure reliable signal transmission and corrosion resistance. The housing is made of black polyamide (PA6T), providing structural integrity and meeting UL94 V-0 flammability ratings. Rated for 3A per contact and 250V, it operates within a temperature range of -40°C to 105°C.

Feature Summary

• Right-angle through-hole termination for compact vertical board integration
• Gold-plated phosphor bronze contacts for durable electrical performance
• Dual-row 38-position layout with 2.54mm pitch for high-density applications

Applications

• Board-to-board interconnects requiring right-angle routing
• Industrial control systems with dense I/O requirements
• Consumer electronics utilizing modular connector assemblies

Procurement Notes

Verify the specific suffix codes against the official Harwin datasheet to confirm right-angle orientation and contact plating specifications. Ensure compatibility with mating header part numbers in the M20 series. Confirm that the through-hole footprint matches the target PCB design guidelines. Check for any recent product change notices regarding material composition or packaging updates.

Selection Notes

Select this component when a right-angle female socket is required for through-hole assembly. The 38-position count suits applications needing substantial I/O density in a single row pair. Consider the 2.54mm pitch for standard component availability. Evaluate the right-angle form factor against space constraints and mating height requirements compared to straight headers.

Part Context

This part belongs to the Harwin M20 series, a widely used line of rectangular connectors known for their robust mechanical design and versatile mounting options. The M20 series offers various configurations including surface mount and through-hole variants in both straight and right-angle styles. This specific model represents the through-hole right-angle female socket variant, complementing the male headers available in the same series.

Replacement Considerations

Direct substitutes within the M20 series include other 38-position right-angle sockets such as M20-7893842 variations with different plating or packaging. Cross-series replacements may require re-evaluation of pitch and mechanical dimensions.
