BL LP 1 21 Z

Headers, Receptacles, Female Sockets Overview

The BL LP 1 21 Z is a 21-position header connector manufactured by Fischer Elektronik. It utilizes a 0.100 inch (2.54 mm) pitch and is designed for through-hole mounting on printed circuit boards. The contacts are constructed from CuSn-alloy with a tin-plated surface finish to ensure reliable electrical connections. The contact sleeve features a nickel base with a gold plating thickness of at least 0.2 micrometers, providing enhanced corrosion resistance and durability for repeated mating cycles.

Headers, Receptacles, Female Sockets Procurement Notes

Verify the specific ordering suffix 'Z' against the manufacturer's current datasheet to confirm exact pin count and mechanical dimensions. Ensure compatibility with standard 2.54 mm pitch PCB layouts. Confirm that the tin-plated contact material meets the environmental requirements of the target application. Cross-reference the part number with official Fischer Elektronik catalogs to avoid confusion with similar series components.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when a 21-position through-hole header is required for rigid PCB connections. The 2.54 mm pitch ensures compatibility with standard wire harnesses and mating connectors. Consider the tin-plated finish for general-purpose applications where high corrosion resistance is not the primary constraint. Verify that the mechanical height and housing material suit the enclosure constraints.
