AW 127-26/Z-HP

Overview

The AW 127-26/Z-HP is a single-row female header connector from the AW 127 series, manufactured by Assmann WSW Components. It features 26 positions with a 2.54 mm (0.1 inch) pin spacing. Designed for through-hole mounting, this straight receptacle utilizes gold-plated contacts to ensure reliable signal transmission. The housing is constructed from polyphenylene sulfide (PPS), providing thermal stability and mechanical strength. Rated for 100V and 12A, it operates within a temperature range of -40°C to 105°C. The component meets UL 94 V-0 flammability standards and complies with RoHS directives.

Feature Summary

• Gold-plated contact surfaces enhance conductivity and corrosion resistance for durable connections.
• Polyphenylene sulfide housing offers high thermal stability and structural integrity.
• Through-hole termination method ensures secure mechanical attachment to printed circuit boards.

Applications

• General-purpose board-to-board interconnections
• Industrial control system wiring
• Consumer electronics assembly

Procurement Notes

Verify that the specific suffix 'Z-HP' corresponds to the gold-plated variant, as standard versions may differ in contact finish. Confirm that the 2.54 mm pitch aligns with the mating header specifications. Ensure the through-hole footprint matches the target PCB design. Check for RoHS compliance documentation if required by project regulations. Validate the current rating against the application's electrical load requirements.

Selection Notes

Select this model when gold plating is necessary for superior contact performance or harsh environments. The 26-position count suits applications requiring moderate channel density. The PPS material is suitable for reflow soldering processes due to its high heat resistance. Consider the straight orientation for standard vertical mounting configurations. Verify compatibility with mating male headers of identical pitch and row configuration.

Part Context

This component belongs to the AW 127 series, which provides a range of single-row connectors. The AW 127-26/Z-HP specifically denotes the 26-position variant with gold contacts. Similar models in the series include AW 127-26/Z-T, which typically features tin plating instead of gold. The series supports various pin counts and termination styles for diverse electronic integration needs.

Replacement Considerations

AW 127-26/Z-T serves as a potential substitute if tin plating is acceptable. Verify that the mechanical dimensions and pin spacing remain identical to ensure PCB compatibility. Confirm that the electrical ratings meet or exceed the original requirements. Assess whether the change in contact material affects long-term reliability in the specific operating environment.
