M20-7830542

Overview

The M20-7830542 is a rectangular connector receptacle from the Harwin M20 series, designed for board-to-board or cable stacking applications. It features 10 female socket contacts arranged in a 2-row configuration with a 2.54mm (0.1 inch) pitch. The component utilizes through-hole mounting technology and is constructed with phosphor bronze contacts finished with nickel plating and a tin overplate. The housing is made of polyamide (PA6T), rated UL94 V-0 for flame resistance. Electrical ratings include a current capacity of 3A and a voltage rating of 1000V. The operating temperature range spans from -40°C to +105°C. Mated stacking heights are specified at 11.04mm and 12.63mm.

Feature Summary

• Dual-row female socket receptacle design for compact board-to-board interconnects
• Through-hole termination method ensures secure PCB attachment
• Polyamide insulation material provides high thermal stability and flame resistance
• Nickel-tin contact plating offers reliable conductivity and corrosion protection

Applications

• General purpose electronic assemblies
• Industrial control systems
• Telecommunications equipment

Procurement Notes

Verify the specific ordering suffix against the official Harwin datasheet to ensure correct contact plating and housing color specifications. Confirm that the 10-position count matches the design requirement. Check for RoHS compliance documentation if required by the manufacturing facility. Ensure the through-hole footprint aligns with the PCB layout guidelines provided in the product drawings.

Selection Notes

Select this component when a low-profile, dual-row female connector is needed for 2.54mm pitch applications. The 3A current rating suits moderate power signals. Consider the 11.04mm/12.63mm stacking height for mechanical clearance constraints. Verify compatibility with mating male headers from the same M20 series to ensure proper engagement and retention.

Part Context

This part belongs to the Harwin M20 series, a widely used line of 2.54mm pitch connectors known for their reliability in industrial environments. The M20 series offers various configurations including headers, sockets, and wire-to-board options. The M20-7830542 specifically addresses the need for multi-position, double-row receptacles in space-constrained designs requiring robust electrical connections.

Replacement Considerations

Direct substitutes within the M20 series should be checked for identical pin counts and row configurations. Cross-referencing with other manufacturers requires verifying pitch, current rating, and mechanical dimensions. Ensure mating parts from alternative sources maintain compatible contact geometries and locking mechanisms.
