Overview
The AW140-EA-G28G is a single-row pin header connector from the ASSMANN WSW AW140 series. It features a 2.54 mm pitch and contains 28 positions. Designed for right-angle through-hole mounting, it utilizes gold-plated brass contacts rated for 3 A current and 250 V voltage. The housing is constructed from polybutylene terephthalate (PBT), supporting an operating temperature range of -40°C to 105°C. This board-to-board connector system provides reliable electrical interconnection with specific tail and mating pin lengths.
Feature Summary
- Right-angle orientation facilitates compact board stacking and space-efficient routing.
- Gold flash plating on brass contacts ensures stable conductivity and corrosion resistance.
- Polybutylene terephthalate housing offers thermal stability within the specified operating range.
Applications
- Board-to-board interconnections in electronic assemblies
- Single-row signal transmission in compact circuit designs
- Through-hole mounting applications requiring right-angle alignment
Procurement Notes
Verify the exact pin count matches the required 28-position configuration before integration. Confirm that the right-angle form factor aligns with the mechanical layout constraints of the target PCB. Ensure the 2.54 mm pitch compatibility with mating connectors is validated against the system design specifications.
Selection Notes
Select this component when a right-angle, single-row header with 28 pins is required. The AW140 series offers consistent 2.54 mm spacing suitable for standard through-hole processes. Consider the specific tail length requirements for the assembly height and ensure the PBT material meets environmental durability needs.
Part Context
This part belongs to the AW140 series of ASSMANN WSW Components, which specializes in high-density board-to-board connectors. The series includes various row counts and orientations, all sharing the 2.54 mm pitch standard. The AW140-EA variant specifically denotes the right-angle configuration within this product line.
Replacement Considerations
AW140-EA-G28H is available as a substitute with identical electrical characteristics but potentially different tail length specifications. Verify mechanical fitment before substitution.
