M20-7892142

Overview

The M20-7892142 is a rectangular connector from the Harwin M20 series, designed as a PCB receptacle with right-angle mounting. It features 21 positions arranged in a single row with a 2.54 mm (0.100 inch) pitch. The contacts are gold-plated phosphor bronze, providing reliable electrical performance. Rated for 3A current and 250V voltage, it operates within a temperature range of -40°C to 105°C. The housing is made of black PA6T nylon with UL94 V-0 flammability rating.

Feature Summary

• Right-angle surface mount design for compact board-to-board connections
• Gold-plated contacts ensure low contact resistance and corrosion resistance
• High-temperature resistant PA6T insulation material supports demanding environments

Applications

• Board-to-board interconnects in industrial control systems
• Signal transmission in automotive electronic modules
• Data communication equipment internal connections

Procurement Notes

Verify the specific suffix '42' corresponds to the standard gold plating configuration. Confirm right-angle orientation matches the mechanical layout requirements. Check RoHS compliance status against current regulatory standards before finalizing procurement orders.

Selection Notes

Select this component when space constraints require a right-angle connection profile. Ensure the mating header has compatible 2.54mm pitch and sufficient contact length. Verify that the 3A per contact rating meets the circuit load requirements without derating issues.

Part Context

This part belongs to the M20 series, known for high-density interconnect solutions. It complements matching headers like the M20-876 series. The series offers various pin counts and mounting styles for flexible system integration.

Replacement Considerations

Direct substitutes include other M20 series right-angle receptacles with equivalent pin counts. Verify mating compatibility with existing headers before substitution.
