ABL-254-72-SR45

Headers, Receptacles, Female Sockets Overview

The ABL-254-72-SR45 is a 72-position, double-row male through-hole pin header manufactured by Assmann WSW Components. It features a 2.54 mm (0.1 inch) pitch and is designed for PCB mounting with a right-angle orientation. The connector utilizes a tin-plated brass contact system housed in a black polyamide 6.6 body rated UL94V-0. Key electrical specifications include a rated current of 3 A per contact and a rated voltage of 300 V AC. The unit supports a maximum operating temperature of 105 °C and offers an insulation resistance exceeding 1000 MΩ at 500 V DC.

Headers, Receptacles, Female Sockets Feature Summary

• Right-angle through-hole mounting configuration for space-efficient PCB integration
• Polyamide 6.6 housing material providing UL94V-0 flame retardancy
• Tin-plated brass contacts ensuring reliable signal transmission and corrosion resistance

Headers, Receptacles, Female Sockets Applications

• Industrial control panel interconnections
• Consumer electronics internal circuit board linking
• Telecommunications equipment signal routing

Headers, Receptacles, Female Sockets Procurement Notes

Verify the specific suffix SR45 against the manufacturer's latest datasheet to confirm plating thickness and material composition details. Ensure the selected variant matches the required right-angle orientation and double-row configuration for the target PCB footprint. Cross-reference the rated current and voltage limits with the application's electrical load requirements before finalizing procurement orders.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when a rigid, right-angle connection is required between two parallel printed circuit boards. The 2.54 mm pitch is standard for general-purpose digital and low-power analog signals. Consider the 3 A current rating and 300 V voltage limit to ensure compliance with the system's electrical safety standards and thermal management requirements.

Headers, Receptacles, Female Sockets Part Context

This part belongs to the ABL series of straight and right-angle pin headers from Assmann WSW. The series is characterized by its robust mechanical design and standardized 2.54 mm spacing, widely used in legacy and modern electronic assemblies. The double-row format allows for higher density connections compared to single-row alternatives within the same footprint constraints.

Headers, Receptacles, Female Sockets Replacement Considerations

Compatible substitutes must match the 72-pin count, 2x36 configuration, 2.54 mm pitch, and right-angle through-hole mounting style. Verify that alternative manufacturers offer identical housing materials and contact plating specifications to maintain environmental and electrical performance equivalence.
