Procurement Notes

Verify current availability status as this component may be subject to obsolescence notices. Confirm that the specific pin count and row configuration match the target PCB footprint requirements. Ensure compliance with RoHS directives if required by the end product specifications. Cross-reference the datasheet for any recent product change notifications affecting material composition or manufacturing location.

Selection Notes

Select this model when high-voltage isolation is critical for the application. The dual-row layout maximizes connection density on limited board space. Verify that the surface-mount package aligns with the assembly capabilities. Consider thermal management requirements given the operating temperature range. Ensure mating connectors adhere to the same 2.54 mm pitch standard for reliable engagement.

Part Context

This part belongs to the M20 series, which offers a range of rectangular connectors for various mounting styles. The M20-7884042 specifically addresses needs for high-pin-count, high-voltage surface-mount interfaces. It complements other M20 variants that differ in row count, pitch, or termination style, providing a standardized solution for dense interconnect challenges.

Replacement Considerations

Check for official substitute part numbers from Harwin if this item is discontinued. Ensure any replacement maintains the 2.54 mm pitch and dual-row structure. Verify voltage and current ratings meet or exceed original specifications. Confirm mechanical compatibility with existing PCB layouts and mating hardware.
