AW140-EA-G31G

Overview

The AW140-EA-G31G is a male pin header from the AW140 series, designed for board-to-board interconnections. It features 31 positions with a 2.54 mm pitch and supports up to 3A current at 250V. The connector utilizes brass contacts with gold plating and a polybutylene terephthalate housing. It is configured for right-angle through-hole mounting with solder termination. Operating temperatures range from -40°C to 105°C. This component provides reliable electrical connectivity in compact electronic assemblies requiring standard spacing.

Feature Summary

• Right-angle orientation facilitates space-efficient PCB layouts
• Gold-plated brass contacts ensure durable conductivity
• Through-hole soldering provides secure mechanical attachment

Applications

• Board-to-board signal transmission
• Electronic module interconnection
• Industrial control circuitry

Procurement Notes

Verify the exact position count against the datasheet, as the model number indicates 31 pins while some sources reference 36-pin variants within the same series. Confirm RoHS compliance status prior to ordering, as documentation varies between compliant and non-compliant designations. Ensure the right-angle configuration matches the assembly requirements. Cross-reference the specific suffix codes to guarantee compatibility with mating connectors and verify the intended operating temperature range for the application environment.

Selection Notes

Select this component when a right-angle male header is required for dense PCB arrangements. The 2.54 mm pitch ensures compatibility with standard breadboard and prototyping systems. Verify that the 3A current rating meets the load requirements of the connected circuits. Consider the housing material properties for environmental resistance. Ensure the through-hole footprint aligns with the target PCB design constraints and manufacturing capabilities.

Part Context

This part belongs to the AW140 series of headers manufactured by Assmann WSW Components. The series offers various configurations including straight and right-angle options with different pin counts. The AW140-EA-G31G specifically denotes the right-angle variant with 31 positions. It shares common design characteristics with other models in the family, such as contact materials and housing compounds, but differs in physical dimensions and terminal length based on the orientation.

Replacement Considerations

Compatible substitutes include other 31-position right-angle headers with 2.54 mm pitch from the same manufacturer or industry equivalents. Verify that replacement parts maintain identical current ratings and voltage specifications. Ensure the mating connector interface matches the pin layout. Check for equivalent thermal performance and mechanical stability requirements before substituting.
