A-BL254-DG-G22D

Headers, Receptacles, Female Sockets Overview

The A-BL254-DG-G22D is a 22-position, double-row female header connector manufactured by Assmann WSW Components. It features a 0.100-inch (2.54mm) pitch and utilizes gold-plated contacts for reliable signal transmission. Designed for through-hole mounting, this receptacle connector supports a rated voltage of 500V and operates within a temperature range of -40°C to 105°C. The housing is constructed from black PBT material reinforced with glass fiber, ensuring UL94 V-0 flammability rating. This component serves as a robust interconnect solution for board-to-board or board-to-cable applications requiring high durability.

Headers, Receptacles, Female Sockets Feature Summary

• Gold-plated female contacts ensure low resistance and corrosion resistance
• Double-row configuration maximizes connection density
• Through-hole termination provides secure mechanical stability
• High-temperature resistant PBT insulation meets UL94 V-0 standards

Headers, Receptacles, Female Sockets Applications

• Industrial control system interconnections
• Consumer electronics board assembly
• Automotive electronic module connections
• Telecommunications equipment interfaces

Headers, Receptacles, Female Sockets Procurement Notes

Verify the specific contact plating thickness and insulation material grade against the official datasheet before integration. Confirm that the through-hole pad layout matches the manufacturer's recommended footprint to ensure proper solder joint integrity. Check RoHS compliance status if required by your manufacturing environment. Ensure mating connectors match the 2.54mm pitch and double-row specification to prevent mechanical interference.

Headers, Receptacles, Female Sockets Selection Notes

Select this model when a durable, high-current capable female header is needed for permanent board mounting. The gold plating makes it suitable for environments where oxidation resistance is critical. Consider the 500V rating for higher voltage applications compared to standard 3A headers. Evaluate the double-row format against available PCB space constraints. Compare against similar AWL series parts if male pin headers are required instead.

Headers, Receptacles, Female Sockets Part Context

This part belongs to the A-BL254 series of rectangular connectors from Assmann WSW Components. The series offers various position counts and row configurations to support diverse connectivity needs. These connectors are designed for general-purpose electronic applications requiring reliable signal and power transfer. The product line emphasizes compatibility with standard PCB fabrication processes and common mating connector types.

Headers, Receptacles, Female Sockets Replacement Considerations

Compatible substitutes include other 22-position, 2.54mm pitch female headers from manufacturers such as Molex, Samtec, or Hirose. Ensure replacement parts maintain the same through-hole mounting style and gold contact plating. Verify that the alternative connector shares the same 500V rating and operating temperature range. Cross-reference the mechanical dimensions to guarantee fit within the existing enclosure and PCB layout.
