AW 127-43/Z-T

Overview

The AW 127-43/Z-T is a single-row female header socket manufactured by Assmann WSW Components. It features 43 contacts with a 0.100-inch (2.54 mm) pitch, designed for through-hole mounting on printed circuit boards. The connector utilizes gold-plated phosphor bronze contacts and a polybutylene terephthalate (PBT) housing rated UL 94 V-0. It supports board-to-board interconnections with a voltage rating of 100V AC and operates within a temperature range of -40°C to +105°C.

Feature Summary

• Single-row receptacle configuration for direct PCB insertion
• Gold-plated phosphor bronze contacts ensure reliable signal transmission
• UL 94 V-0 rated PBT housing provides thermal stability
• Through-hole termination method ensures secure mechanical attachment

Applications

• Board-to-board interconnection systems
• Industrial control panel wiring
• Consumer electronics assembly
• Communication equipment interfaces

Procurement Notes

Verify the specific contact count matches the '43' designation in the model number before ordering. Confirm that the gold plating specification aligns with your conductivity requirements. Ensure the through-hole footprint corresponds to the 2.54 mm pitch dimensions provided in the official datasheet to prevent soldering defects during assembly.

Selection Notes

Select this component when a high-density single-row interface is required for rigid board connections. The 43-position capacity suits applications needing extensive I/O lines in a linear format. Consider the 100V AC rating and operating temperature limits to ensure compatibility with the target environment's electrical and thermal conditions.

Part Context

This part belongs to the AW 127 series of rectangular connectors from Assmann WSW Components. The series offers various pin counts, all sharing the same 2.54 mm pitch and through-hole mounting style. The '/Z-T' suffix typically denotes specific material or plating variations within the standard product line, ensuring consistency across different configurations.

Replacement Considerations

AW 127-43/G-T serves as a potential substitute if tin plating is acceptable instead of gold. Other pin counts in the AW 127 series may be used if the circuit design allows for fewer connections.
