Procurement Notes
Verify the specific ordering suffix against the manufacturer datasheet to confirm plating type and housing color variations. Ensure compatibility with the target PCB edge thickness and mounting hole dimensions. Confirm RoHS compliance status through official documentation before finalizing procurement specifications.
Selection Notes
Select this component when a high-density 50-position interface is required with a 3.96 mm pitch. The vertical panel mount style suits applications needing direct chassis integration. Verify that the 5 A current rating meets circuit requirements and that the operating temperature range aligns with environmental conditions.
Part Context
This part belongs to the EDAC 306 series of standard card edge connectors. The series offers various position counts and mounting styles. The 306-025-421-108 specifically provides a dual-edge solution with gold contacts, distinguishing it from single-row or tin-plated variants within the same family.
Replacement Considerations
Cross-reference with EDAC 306-025-520-107 for similar specifications but verify header versus receptacle differences. Check EDAC 306-010-421-108 for lower position count alternatives. Ensure mechanical fit and electrical ratings match before substitution.
