A-BL254-EG-G21MR1

Headers, Receptacles, Female Sockets Overview

The A-BL254-EG-G21MR1 is a surface mount receptacle connector from the ASSMANN WSW A-BL254 series. It features 21 positions with a 0.100 inch (2.54mm) pitch. The connector utilizes gold-plated contacts for reliable signal transmission and is designed for right-angle installation on printed circuit boards. This component serves as a female socket interface, providing secure mating connections for corresponding pin headers in electronic assemblies requiring compact surface-mount solutions.

Headers, Receptacles, Female Sockets Feature Summary

• Surface mount technology design for automated PCB assembly
• Gold-plated contact surfaces ensuring corrosion resistance and stable conductivity
• Right-angle orientation facilitating efficient board space utilization

Headers, Receptacles, Female Sockets Applications

• Consumer electronics internal interconnections
• Industrial control module interfaces
• Telecommunications equipment board-to-board connections

Headers, Receptacles, Female Sockets Procurement Notes

Verify that the specific suffix EG indicates surface mount compatibility and right-angle configuration. Confirm the 21-position count matches the target design requirements. Ensure the gold plating specification aligns with environmental durability needs. Cross-reference the datasheet for precise mechanical dimensions to guarantee clearance within the enclosure.

Headers, Receptacles, Female Sockets Selection Notes

Choose this part when surface mounting is required rather than through-hole alternatives. The right-angle form factor is suitable for dense layouts where vertical clearance is limited. Verify that the mating header matches the 2.54mm pitch and 21-position count. Consider the operating temperature range and UL certification if safety compliance is mandatory for the end application.

Headers, Receptacles, Female Sockets Part Context

This component belongs to the A-BL254 series of board connectors manufactured by ASSMANN WSW Components. The series offers various configurations including different row counts, termination styles, and orientations. The A-BL254-EG-G21MR1 specifically addresses the need for high-density surface-mount receptacles with durable gold contacts in standard pitch applications.

Headers, Receptacles, Female Sockets Replacement Considerations

Direct substitutes must match the 21-position count, 2.54mm pitch, surface mount termination, and right-angle orientation. Verify identical housing material properties and contact plating specifications. Check for compatible mating header dimensions to ensure proper engagement without mechanical interference.
