A-BL254-DG-Z70D

Headers, Receptacles, Female Sockets Overview

The A-BL254-DG-Z70D is a through-hole pin header connector manufactured by Assmann WSW Components. It features 70 positions arranged in two rows with a 2.54mm pitch. The connector utilizes square male pins made of brass with tin plating for reliable electrical contact. The housing is constructed from black, glass-reinforced PBT plastic rated UL94 V-0 for flame resistance. Designed for board-to-cable or wire applications, it supports a maximum current of 3A and operates within a temperature range of -40°C to 105°C.

Headers, Receptacles, Female Sockets Feature Summary

• Two-row pin header configuration with cuttable design for flexible length selection
• Square male pin geometry ensures secure mating stability
• Flame-retardant glass-reinforced PBT insulation housing
• Tin-plated brass contacts provide corrosion resistance

Headers, Receptacles, Female Sockets Applications

• Board-to-cable interconnections
• Wire-to-board connections
• General electronic assembly requiring high-density I/O

Headers, Receptacles, Female Sockets Procurement Notes

Verify the specific part number against official manufacturer documentation to confirm pin count and series alignment. Ensure compatibility with mating receptacles regarding pitch and row configuration. Check for RoHS compliance status if required by project specifications. Confirm that the through-hole mounting style matches the target PCB layout requirements.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when a 70-position, two-row header is required for through-hole implementation. Consider the 2.54mm pitch standard for broad mating availability. Evaluate the 3A current rating against circuit load requirements. Verify that the black PBT housing meets environmental and thermal constraints for the intended operating conditions.

Headers, Receptacles, Female Sockets Part Context

This connector belongs to the AWL254/A-BL254 series of rectangular connectors from Assmann WSW Components. The series is characterized by standardized 2.54mm spacing and robust mechanical construction. These components are widely used in industrial and consumer electronics for reliable signal and power transmission between boards and cables.

Headers, Receptacles, Female Sockets Replacement Considerations

Compatible substitutes include other 70-position, 2x35, 2.54mm pitch through-hole headers from manufacturers such as Molex, Samtec, or TE Connectivity. Ensure exact dimensional matching for housing width and pin length. Verify identical current ratings and material compositions for equivalent performance.
