Overview
The AW140-EA-Z21J is a single-row, right-angle pin header connector from the ASSMANN WSW AW140 series. It features 21 positions with a 2.54 mm pitch and is designed for board-to-board connections via through-hole mounting. The contacts are gold-plated brass, rated for 3 A current and 250 V voltage. The housing is made of polybutylene terephthalate (PBT), supporting an operating temperature range of -40°C to 105°C.
Feature Summary
- Right-angle orientation facilitates compact vertical circuit board stacking.
- Gold-plated brass contacts ensure reliable signal transmission and corrosion resistance.
- Through-hole termination provides secure mechanical anchoring on printed circuit boards.
Applications
- Board-to-board interconnections in electronic assemblies
- Vertical stacking of daughter cards or expansion modules
- General-purpose signal routing in industrial control systems
Procurement Notes
Verify the specific suffix 'Z21J' against the manufacturer's official datasheet to confirm exact contact plating thickness and material specifications. Ensure the ordering quantity aligns with standard packaging units defined by ASSMANN WSW Components. Cross-reference the part number with authorized distributors to confirm current availability and compliance with relevant environmental standards.
Selection Notes
Select this component when a right-angle, single-row configuration is required for space-constrained vertical mounting. The 2.54 mm pitch is suitable for standard digital and low-power analog signals. Consider the PBT housing material for thermal stability and the gold plating for long-term reliability in environments where oxidation resistance is critical for contact integrity.
Part Context
This connector belongs to the AW140 series, which offers various pin counts and orientations. The AW140-EA variant specifically denotes the right-angle design. This series is widely used in consumer electronics and industrial equipment requiring robust, low-profile interconnect solutions that support through-hole assembly processes for enhanced mechanical strength.
Replacement Considerations
Compatible substitutes include other 21-position, 2.54 mm pitch right-angle headers from manufacturers such as Molex, Samtec, or Hirose. Ensure that replacement parts match the original height, contact plating requirements, and PCB footprint dimensions to maintain mechanical fit and electrical performance without redesigning the host board.
