A-BL254-EA-Z21D

Headers, Receptacles, Female Sockets Overview

The A-BL254-EA-Z21D is a 21-position female header connector from the ASSMANN WSW A-BL254 series. It features a 2.54 mm (0.100 inch) pitch and utilizes through-hole mounting for secure PCB attachment. The connector is designed in a right-angle configuration to facilitate space-efficient circuit layouts. Contacts are constructed from stamped metal with tin plating to ensure reliable electrical conductivity and corrosion resistance.

Headers, Receptacles, Female Sockets Feature Summary

• Right-angle orientation for compact board integration
• Through-hole termination method for mechanical stability
• Tin-plated stamped contacts for signal integrity

Headers, Receptacles, Female Sockets Applications

• General-purpose electronic assemblies requiring right-angle connections
• Consumer electronics internal wiring harnesses
• Industrial control panel interconnects

Headers, Receptacles, Female Sockets Procurement Notes

Verify that the specific part number A-BL254-EA-Z21D matches the required 21-position count, right-angle orientation, and through-hole pin style. Confirm that tin plating meets the environmental requirements of the target application, as gold plating options may exist within the same series for different performance needs.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when a right-angle female header is necessary to connect mating pins or cables at a 90-degree angle to the printed circuit board. Ensure the design accommodates the through-hole footprint dimensions and that the tin contact material is suitable for the expected current load and mating cycle frequency without requiring high-conductivity gold plating.

Headers, Receptacles, Female Sockets Part Context

This component belongs to the A-BL254 series, which provides various configurations of 2.54 mm pitch headers. The series includes both single and double row options with different terminal counts and orientations. This specific model represents the right-angle variant with tin contacts, distinguishing it from straight-mount or gold-plated alternatives within the same product family.

Headers, Receptacles, Female Sockets Replacement Considerations

Compatible substitutes include other 21-position, 2.54 mm pitch right-angle female headers with through-hole terminals. Verify that alternative manufacturers offer identical pin spacing and housing dimensions to ensure mechanical compatibility with existing PCB footprints and mating connectors.
