AW 127-45/Z-T

Overview

The AW 127-45/Z-T is a single-row female header connector from the AW 127 series by Assmann WSW Components. It features 45 positions with a 2.54 mm (0.100 inch) pitch, designed for board-to-board connections via through-hole soldering. The connector supports a voltage rating of 100V and a current capacity of 12A. Constructed with a polybutylene terephthalate (PBT) housing and phosphor bronze contacts plated with gold, it operates within a temperature range of -40°C to +105°C. The unit complies with UL 94 V-0 flammability standards.

Feature Summary

• Single-row female header configuration for reliable board-to-board interconnects
• Through-hole termination method ensures secure mechanical mounting on printed circuit boards
• Gold-plated phosphor bronze contacts provide durable conductivity and corrosion resistance
• Polybutylene terephthalate housing offers structural stability and meets UL 94 V-0 flammability requirements

Applications

• High-density electronic assemblies requiring robust board-to-board signal transmission
• Industrial control systems operating within extended temperature environments
• Consumer electronics utilizing standard 2.54 mm spacing interfaces
• Automotive internal modules demanding high current carrying capability

Procurement Notes

Verify the specific contact plating specification against the manufacturer's datasheet, as some listings may indicate tin or gold variants. Confirm that the 45-position count aligns with your PCB footprint design. Ensure the through-hole pad layout matches the 2.54 mm pitch dimensions. Check for RoHS compliance status if required by your manufacturing standards. Validate the voltage and current ratings against your application's electrical load requirements before finalizing procurement.

Selection Notes

Select this component when a single-row female header with 45 positions is required for direct board stacking. The 2.54 mm pitch is standard for general-purpose interconnects, ensuring compatibility with common mating pins. Consider the 12A current rating for power distribution applications alongside signal lines. The through-hole installation provides superior mechanical strength compared to surface-mount alternatives. Verify housing material compatibility with your assembly process temperatures.

Part Context

This part belongs to the AW 127 series of rectangular connectors, which are widely used in industrial and commercial electronics. The series offers various pin counts and configurations to support diverse connectivity needs. Assmann WSW Components manufactures these connectors to meet rigorous quality standards, ensuring consistent performance across different environmental conditions. The AW 127 series is known for its reliability in high-density applications.

Replacement Considerations

Direct substitutes include other 45-position, 2.54 mm pitch female headers from manufacturers such as Molex, TE Connectivity, or Samtec. Ensure replacement parts match the through-hole termination style and housing material specifications. Verify that the mating pin dimensions and current ratings are compatible. Cross-reference the mechanical drawings to confirm footprint compatibility.
