AW140-EA-Z29H

Overview

The AW140-EA-Z29H is a single-row pin header from the AW140 series, manufactured by Assmann WSW Components. It features a 2.54 mm pitch and contains two contacts designed for board-to-board connections. The connector utilizes brass contacts with a tin finish on the mating side, housed in an insulation body made of polybutylene terephthalate (PBT). This component is configured as a right-angled pin socket intended for through-hole mounting. Key dimensional specifications include a contact shape that is square, an insulation height of 2.50 mm, and specific pin lengths where dimension A measures 5.72 mm and dimension B measures 2.4 mm.

Feature Summary

• Right-angled configuration for space-efficient board stacking
• Through-hole termination method for secure PCB attachment
• Tin-plated mating contacts to ensure reliable conductivity

Applications

• Automotive body electronics
• Communications equipment
• Datacom modules
• Personal electronics

Procurement Notes

Verify the exact contact count and plating specification against the official datasheet, as distributor listings may vary between gold flash and tin finishes for similar part numbers within the AW140 series. Confirm the insulation material is PBT and check if the specific suffix 'Z' indicates a distinct variant compared to standard 'G' or 'E' suffixes. Ensure the right-angle orientation matches the design requirement before finalizing procurement orders.

Selection Notes

Select this component when a low-profile, right-angle interconnect is required for automotive or datacom applications. The 2.54 mm pitch is standard for general-purpose connections, while the tin finish offers cost-effective conductivity. Consider the 2.50 mm insulation height for clearance constraints. Evaluate the mechanical stability provided by the through-hole mounting style versus surface mount alternatives for the specific vibration environment of the target application.

Part Context

This part belongs to the AW140 series, which provides various configurations of pin headers for Assmann WSW Components. The series supports different row counts, orientations, and contact materials. The AW140-EA-Z29H specifically addresses the need for compact, right-angled connections in consumer and industrial electronics, offering a standardized footprint compatible with common PCB layouts.

Replacement Considerations

Direct substitutes within the same manufacturer series include AW140-EA-G06H and AW140-EA-G36H, though these differ significantly in contact count and potentially plating. Verify compatibility regarding the insulation material and terminal length dimensions when considering cross-references.
