A-BL254-DG-Z78D

Headers, Receptacles, Female Sockets Overview

The A-BL254-DG-Z78D is a pin header connector manufactured by Assmann WSW Components, belonging to the AWL254 series. It features a 2.54mm pitch and is designed for through-hole mounting with solder termination. The component consists of 78 positions arranged in two rows, providing a total of 78 male pins. Constructed with brass contacts featuring tin plating and reinforced polybutylene terephthalate (PBT) insulation rated UL94 V-0, it supports a current rating of 3A and operates within a temperature range of -40°C to 105°C.

Headers, Receptacles, Female Sockets Feature Summary

• Features a cuttable design allowing for flexible configuration of contact counts
• Utilizes square-shaped male pins for secure mating connections
• Constructed with glass-reinforced PBT insulation for thermal stability

Headers, Receptacles, Female Sockets Applications

• Board-to-cable or board-to-wire interconnections
• High-density signal routing on PCBs
• Industrial control system interfaces

Headers, Receptacles, Female Sockets Procurement Notes

Verify the specific pin count and row configuration against project requirements before ordering. Confirm that the tin-plated contacts meet the environmental and corrosion resistance standards for the intended application. Ensure the through-hole footprint matches the PCB layout guidelines provided in the official datasheet to guarantee proper mechanical retention and electrical performance.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when a high-count, double-row male header is required for rigid board-to-board or cable connections. The 2.54mm pitch ensures compatibility with standard ribbon cables and mating connectors. Consider the cuttable feature if exact pin counts vary across production batches, allowing for cost-effective inventory management while maintaining consistent electrical characteristics.

Headers, Receptacles, Female Sockets Part Context

This part belongs to the AWL254 series of pin headers from Assmann WSW Components. The series is characterized by its 2.54mm spacing and robust construction suitable for general-purpose electronic applications. The model number indicates specific attributes such as the 78-position count and double-row arrangement, distinguishing it from single-row or lower-count variants within the same product family.

Headers, Receptacles, Female Sockets Replacement Considerations

Compatible substitutes include other 2.54mm pitch, 78-position, double-row male pin headers from manufacturers such as Molex, Samtec, or TE Connectivity. Ensure replacement parts match the critical dimensions, including overall height, contact length, and insulation material properties, to maintain mechanical fit and electrical reliability.
