AW 127-54/Z-T

Overview

The AW 127-54/Z-T is a single-row female header connector from the ASSMANN WSW AW 127 series, designed for board-to-board applications. It features 54 contacts with a 2.54 mm pitch and utilizes through-hole termination for secure PCB mounting. The connector operates at a rated voltage of 100 V AC and supports a current rating of 12 A. Constructed with phosphor bronze contacts that are tin-plated, it ensures reliable signal transmission. The housing is made of polybutylene terephthalate (PBT), offering UL 94 V-0 flammability rating. It functions within an operating temperature range of -40°C to +105°C.

Feature Summary

• Single-row female header configuration for direct board-to-board interconnection
• Through-hole solder termination ensures robust mechanical attachment to printed circuit boards
• Tin-plated phosphor bronze contacts provide durable conductivity and corrosion resistance
• Polybutylene terephthalate housing meets UL 94 V-0 flammability standards

Applications

• High-density electronic assemblies requiring multiple signal connections
• Industrial control systems utilizing standard 2.54 mm spacing interfaces
• Consumer electronics manufacturing involving board stacking or mating connectors

Procurement Notes

Verify the specific contact count and orientation against project requirements before ordering. Confirm that the tin-plated finish aligns with soldering process compatibility. Ensure the through-hole footprint matches the design layout. Check for any specific handling instructions regarding the PBT material properties during assembly.

Selection Notes

Select this component when a high-contact-count female header is required for board-to-board linking. The 2.54 mm pitch is standard for many legacy and general-purpose designs. Consider the 12 A current rating for power distribution needs alongside signal lines. The straight orientation suits vertical mating scenarios where space allows for perpendicular connection between boards.

Part Context

This part belongs to the AW 127 series, which offers various pin counts and configurations. Similar parts include AW 127-20/Z-T and AW 127-32/G-T, differing primarily in contact quantity. The series maintains consistent pitch and housing dimensions across variants, facilitating modular design approaches within ASSMANN WSW's connector portfolio.

Replacement Considerations

Direct substitutes may include other manufacturers' 2.54 mm pitch single-row female headers with equivalent current and voltage ratings. Verify mechanical compatibility, including housing width and pin alignment, before cross-referencing. Ensure the replacement part also meets UL 94 V-0 requirements if flame retardancy is critical.
