1577642-1

Overview

TE Connectivity AMP Connectors part number 1577642-1 is a ring terminal connector designed for high-performance applications. It utilizes PEEK insulation and features a PIDG (Press Insulation Grip) termination method. The component supports wire gauges ranging from 14 to 18 AWG, ensuring secure electrical connections in demanding environments.

Feature Summary

• Utilizes PEEK insulation material for superior thermal stability and chemical resistance compared to standard thermoplastics.
• Features PIDG technology that combines press-fit insulation grip with crimped conductor contact for enhanced mechanical retention.
• Designed as a ring terminal to facilitate secure bolted connections in various electronic assemblies.

Applications

• High-temperature automotive electrical systems
• Industrial control panel wiring
• Aerospace harness interconnections

Procurement Notes

Verify the specific insulation color and stud size requirements against your assembly drawings before ordering. Confirm that the PEEK material specification aligns with your project's thermal management constraints. Ensure compatibility with existing crimping tooling designed for PIDG terminals to maintain connection integrity.

Selection Notes

Select this component when operating temperatures exceed the limits of standard nylon or PVC insulated terminals. The PEEK material offers better dielectric strength and flame retardancy. Consider the PIDG termination for applications requiring higher vibration resistance than standard crimp-only terminals provide.

Part Context

This terminal belongs to the Stratoh series, which focuses on high-reliability interconnect solutions. It serves as a direct replacement for obsolete parts like 50847, maintaining similar form factors while upgrading material performance. The series is engineered for harsh environment durability.

Replacement Considerations

The manufacturer lists 50847 as an obsolete part with 1577642-1 as the recommended substitute. Verify physical dimensions and stud hole sizes to ensure mechanical fitment in existing enclosures before switching from legacy inventory.
