AW140-EG-G50A

Overview

The AW140-EG-G50A is a single-row male pin header from the AW140 series, manufactured by ASSMANN WSW. It features a 2.54 mm pitch and supports up to 3A current with a 250V rating. Constructed with brass contacts gold-plated for conductivity, the housing utilizes polybutylene terephthalate (PBT). Designed for through-hole board-to-board mounting, it operates between -40°C and 105°C. The component includes a push-pull fastening mechanism and specific contact lengths: 6.10mm for mating and 0.240 inches for the post.

Feature Summary

• Incorporates a push-pull fastening mechanism for secure connection retention
• Utilizes gold-plated brass contacts to ensure reliable signal transmission
• Features a polybutylene terephthalate housing for thermal stability

Applications

• Board-to-board interconnections in electronic assemblies
• High-density circuit board stacking applications
• Industrial control system module connections

Procurement Notes

Verify the exact pin count and physical dimensions against the official datasheet before procurement, as suffixes often indicate specific mechanical variations. Confirm that the push-pull locking style matches the assembly requirements. Ensure the through-hole termination method aligns with the manufacturing process capabilities of the target printed circuit board.

Selection Notes

Select this model when a robust, locked connector interface is required for vertical board stacking. The 2.54 mm pitch suits standard density layouts. Consider the operating temperature range of -40°C to 105°C for environmental suitability. Verify that the specific contact length parameters meet the clearance needs of the adjacent components in the design.

Part Context

This component belongs to the AW140 series of ASSMANN WSW connectors, which are designed for high-reliability board-to-board applications. The series typically offers various configurations to accommodate different spacing and locking needs. This specific part represents a variant within that family, distinguished by its unique mechanical locking feature and dimensional specifications.

Replacement Considerations

Direct substitutes must match the 2.54 mm pitch, through-hole termination, and push-pull locking mechanism. Verify compatibility with existing PCB footprints and mating housing dimensions. Generic headers lacking the specific locking feature may not provide equivalent retention strength.
