1577629-1

Overview

The TE Connectivity AMP Connectors part number 1577629-1 is a partially insulated ring terminal designed for electrical interconnections. It belongs to the PIDG and Strato-Therm series, featuring a closed barrel type construction. The component is engineered for a wire size of 20 AWG and accommodates a stud size of 0.375 inches. It utilizes a crimp termination method and is constructed with copper contact material. The insulation sleeve is made from PEEK (Polyether ether ketone) and is colored gray. The terminal is rated for an operating temperature range up to 260 °C (500 °F) and has a current rating of 1 A.

Feature Summary

• Features a partially insulated design with a closed barrel for secure crimping
• Constructed with PEEK insulation material for high thermal stability
• Utilizes copper contact material for reliable electrical conductivity

Applications

• High-temperature electrical circuit connections
• Applications requiring 20 AWG wire termination
• Connections involving 0.375 inch stud sizes

Procurement Notes

Verify the specific insulation style matches the requirement for partial coverage rather than full insulation. Confirm that the 20 AWG wire gauge specification aligns with the cable being terminated. Ensure the 0.375 inch stud size is compatible with the mounting hardware in the assembly. Check for any specific RoHS or REACH compliance documentation if required by the end-use environment.

Selection Notes

Select this terminal when high thermal resistance is critical, as indicated by the 260 °C rating. The PEEK insulation offers superior performance compared to standard materials in harsh environments. Ensure the application does not require a fully insulated barrel, as this model is partially insulated. Verify that the 1 A current rating is sufficient for the intended load.

Part Context

This component is part of the PIDG and Strato-Therm product lines from TE Connectivity AMP Connectors. These series are known for providing robust terminal solutions for demanding industrial applications. The Strato-Therm designation specifically highlights the capability to withstand elevated temperatures, making it suitable for specialized automotive or aerospace wiring harnesses where heat dissipation is a concern.

Replacement Considerations

Direct substitutes may include other partially insulated ring terminals from the same manufacturer with identical 20 AWG and 0.375 inch specifications. Cross-referencing with generic PIDG series equivalents is possible if the PEEK insulation and high-temperature rating are not strictly required.
