Procurement Notes
Verify the specific suffix codes against the manufacturer's latest documentation to confirm exact pin count and orientation, as variations exist within the A-BL127 series. Ensure compatibility with standard 1.27mm pitch mating connectors. Cross-reference the part number with official distributor catalogs to confirm current availability status and lead times prior to finalizing procurement plans.
Selection Notes
Select this component when a high-density 74-position interface is required for surface-mounted applications. The 1.27mm pitch allows for compact circuit board layouts while maintaining robust electrical connections. Consider the right-angle or straight orientation options available in the series to match mechanical constraints of the enclosure design.
Part Context
This part belongs to the A-BL127 series of board-to-board connectors from Assmann WSW Components. The series offers various position counts and mounting styles, providing flexibility for different electronic assembly needs. The company specializes in standard and custom-tailored connectors, ensuring consistent quality across their product lines.
Replacement Considerations
Compatible substitutes include other 74-position, 1.27mm pitch surface mount female headers from manufacturers such as Molex, Samtec, or JAE. Verify that alternative parts match the critical dimensions, contact material specifications, and peak reflow temperature ratings to ensure functional equivalence.
