Procurement Notes
Verify current availability status as the manufacturer has scheduled this part for obsolescence. Confirm that end-of-life notices do not impact immediate production needs. Request last-time buy quantities if required for long-term support. Ensure compatibility with existing PCB footprints before procurement.
Selection Notes
Select this component only if 52 positions and 2.54 mm pitch are strictly required. Verify that surface mount technology aligns with manufacturing capabilities. Consider the bottom entry orientation for mechanical clearance. Evaluate alternative active parts if supply chain stability is critical for the project lifecycle.
Part Context
This connector belongs to the Harwin M20 series, which provides versatile interconnect solutions for various electronic applications. The series offers multiple row configurations and termination styles. This specific model represents a high-pin-count variant suitable for complex signal routing needs.
Replacement Considerations
No public confirmed substitute part numbers are available. Due to the scheduled obsolescence, engineers must identify equivalent active components from the same or other manufacturers. Validate pinout compatibility and mechanical dimensions when selecting alternatives.
