Procurement Notes
This component is officially designated as End-of-Life (EOL) by Harwin Inc. Procurement verification must confirm current stock availability through authorized distributors or secondary market suppliers. Buyers should review official Product Change Notification (PCN) documents for obsolescence timelines and recommended replacement strategies to ensure supply chain continuity.
Selection Notes
Engineers selecting this connector must account for its 56-position capacity and 2.54 mm pitch constraints within the design layout. Verification of mating pin dimensions and stack-up height requirements is essential for mechanical compatibility. Due to the EOL status, alternative sourcing channels require rigorous authenticity validation before integration into production systems.
Part Context
The M20-7882846 belongs to the Harwin M20 series, a widely recognized family of rectangular connectors known for robust performance in demanding environments. This series typically offers various row counts and termination options to accommodate diverse electronic packaging needs. The specific model represents a high-pin-count variant optimized for dense circuit board architectures.
Replacement Considerations
Harwin recommends evaluating the M20-78828xxP series or updated M20 variants with similar pin counts and pitches as potential substitutes. Cross-referencing datasheets for mechanical footprint and electrical rating compatibility is mandatory before implementing any replacement component.
