Overview
The AW140-EA-Z28G is a single-row male pin header manufactured by ASSMANN WSW Components. It features a 2.54 mm pitch and contains 28 contacts designed for board-to-board connections. The connector utilizes gold-plated brass terminals with a through-hole solder termination type. Constructed with a PBT housing, it supports a rated voltage of 250V and a current capacity of 3A. The unit operates within a temperature range of -40°C to +105°C and is available in a right-angle configuration without a cover.
Feature Summary
- Right-angle design facilitates compact vertical circuit board interconnections
- Gold-plated brass contacts ensure reliable signal transmission and corrosion resistance
- PBT housing material provides structural stability and thermal endurance
Applications
- Board-to-board electrical interconnection systems
- Industrial electronic control modules
- Consumer electronics internal wiring harnesses
Procurement Notes
Verify the specific contact count and orientation against project requirements before ordering. Confirm that the terminal plating and housing material meet environmental specifications. Ensure compatibility with mating female connectors regarding pitch and row configuration. Check for any specific handling precautions related to the through-hole soldering process during assembly.
Selection Notes
Select this component when a right-angle, single-row male header is required for rigid PCB stacking. The 2.54 mm pitch is standard for general-purpose digital and low-power analog signals. Consider the 3A current rating for power distribution lines if applicable. Verify that the operating temperature range aligns with the intended deployment environment.
Part Context
This part belongs to the AW140 series, which offers various pin counts and configurations from the manufacturer. The series is characterized by its robust construction and consistent 2.54 mm spacing. Similar parts in the lineup differ primarily in the number of positions or the angle of the pins, allowing for flexible system design options.
Replacement Considerations
Direct substitutes include other ASSMANN WSW headers with identical 28-position, right-angle, gold-plated specifications. Cross-manufacturer replacements must match the 2.54 mm pitch, 3A rating, and PBT housing material to ensure mechanical fit and electrical performance equivalence.
