Overview
The AW140-EG-G38C1 is a single-row pin header from the ASSMANN WSW AW140 series, designed for board-to-board connections. It features 38 contacts with a 2.54 mm pitch and operates at 250V with a 3A current rating. The connector utilizes gold-plated brass contacts housed in a PBT insulator. It is a straight, unshrouded male header intended for through-hole mounting via soldering. The component supports an operating temperature range of -40°C to 105°C.
Feature Summary
- Single-row configuration for compact circuit board integration
- Gold flash plating on brass contacts for reliable conductivity
- Straight orientation suitable for standard vertical mounting
- Through-hole termination method for secure PCB attachment
Applications
- Board-to-board interconnects in electronic assemblies
- Signal transmission in industrial control systems
- Connection points in consumer electronics hardware
Procurement Notes
Verify the specific contact count and housing material against official datasheets prior to ordering. Ensure compatibility with mating socket specifications regarding pitch and height. Confirm that the through-hole soldering process aligns with your manufacturing capabilities and thermal requirements for the PBT material.
Selection Notes
Select this component when a high-density single-row connection is required. The 2.54 mm pitch offers a balance between signal density and spacing. Consider the 3A current rating and 250V voltage limit to ensure they meet the electrical demands of the target application environment.
Part Context
This part belongs to the AW140 series, which provides various pin header options for ASSMANN WSW. The series includes different row counts, orientations, and contact numbers. This specific model represents a high-pin-count variant within the straight, single-row category.
Replacement Considerations
Compatible substitutes include other AW140 series headers with matching 2.54 mm pitch and 38 contacts, such as AW140-EG-G38G or similar variants from the same manufacturer family, provided mechanical dimensions are identical.
