Overview
The M20-7882042 is a surface mount socket assembly manufactured by Harwin Inc. within the M20 series. It features a dual-row configuration with 40 positions and a 2.54 mm (0.1 inch) pitch. The connector utilizes solder pin termination for PCB mounting. Contact materials are specified as phosphor bronze with gold plating on the mating surfaces to ensure reliable electrical performance.
Feature Summary
- Dual-entry receptacle design compatible with both top and bottom insertion
- Surface mount installation style for automated PCB assembly
- Gold-plated contacts for enhanced conductivity and corrosion resistance
Applications
- Board-to-board interconnections
- High-density electronic assemblies
- Industrial control systems
Procurement Notes
Verify the specific datasheet version and RoHS compliance status directly with Harwin or authorized distributors before procurement. Confirm that the dual-row SMT footprint matches the target PCB layout. Check for any recent product change notifications or obsolescence alerts associated with this part number to ensure long-term supply stability.
Selection Notes
Select this component when a low-profile, dual-row surface mount solution is required. Ensure the mating header has a compatible 2.54 mm pitch and appropriate contact gender. Consider the mechanical stacking height requirements and verify that the solder mask clearance around the SMT pads meets manufacturing standards for reliable reflow soldering.
Part Context
This part belongs to the Harwin M20 series, which provides high-reliability interconnect solutions. The M20-786xx42 suffix indicates a single-row variant, while the M20-788xx42 designation specifically identifies the dual-row configuration. This series is designed for applications requiring robust mechanical retention and consistent electrical contact in compact spaces.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. For equivalent specifications, consider other Harwin M20 series dual-row SMT sockets with matching pin counts and pitch. Verify mechanical dimensions and electrical ratings against the original design requirements before substitution.
