AW 127-29/Z-HP

Overview

The AW 127-29/Z-HP is a single-row female header connector manufactured by Assmann WSW Components. It features 29 positions with a 2.54 mm (0.1 inch) pin spacing and is designed for through-hole mounting. The contacts are gold-plated, while the termination pins utilize tin plating over a nickel barrier. Constructed with a polybutylene terephthalate (PBT) housing, it supports a maximum voltage of 100V and operates within a temperature range of -40°C to +105°C.

Feature Summary

• Gold-plated contact surfaces ensure reliable signal transmission and corrosion resistance
• Polybutylene terephthalate housing provides high thermal stability and UL 94 V-0 flammability rating
• Through-hole termination facilitates secure mechanical attachment to printed circuit boards

Applications

• General-purpose board-to-board interconnections
• Industrial control system module interfaces
• Consumer electronics assembly requiring robust connectivity

Procurement Notes

Verify that the specific suffix 'Z-HP' corresponds to the required gold contact finish and PBT material grade. Confirm that the 29-position configuration matches the target PCB footprint. Ensure compliance with RoHS directives if environmental regulations apply to the final product assembly. Cross-reference the manufacturer's latest datasheet to validate current production status and any potential design revisions before finalizing procurement orders.

Selection Notes

Select this component when a high-density single-row interface is required with enhanced contact durability. The gold plating offers superior performance in environments prone to oxidation compared to standard tin finishes. Verify that the 100V rating and 105°C operating limit meet the electrical and thermal requirements of the application. Consider the through-hole mounting style for applications prioritizing mechanical strength over surface-mount space constraints.

Part Context

This part belongs to the AW 127 series, which provides a standardized solution for single-row female headers. The series is characterized by its consistent 2.54 mm pitch and robust construction materials. Variations within the series typically differ by position count and contact plating options, allowing designers to scale connectivity density while maintaining uniform mechanical and electrical characteristics across assemblies.

Replacement Considerations

Compatible substitutes include the AW 127-29/Z-T variant, which utilizes tin-plated contacts instead of gold. Designers must verify that the lower-cost tin option meets the corrosion resistance requirements of the intended environment. Other series connectors may require significant PCB layout modifications due to differing pitch or housing dimensions.
