55A0111-20-0CS3530

Overview

The TE Connectivity 55A0111-20-0CS3530 is a Spec 55 hook-up wire manufactured by Raychem. It features a 20 AWG tinned copper conductor with a 19x32 stranding configuration. The insulation consists of radiation cross-linked ethylene tetrafluoroethylene (ETFE). This component is rated for 600 volts and operates at temperatures up to +150°C. The cable has an outer diameter of 1.27 mm and is supplied on a spool.

Feature Summary

• Radiation cross-linked ETFE insulation provides high thermal stability and chemical resistance.
• Tinned copper conductor ensures reliable electrical conductivity and corrosion protection.
• Spec 55 classification indicates compliance with specific military-grade performance standards.

Applications

• Aviation wiring systems
• Defense electronics interconnects
• Industrial control panels

Procurement Notes

Verify the CS3530 suffix against official TE Connectivity documentation to confirm specific color coding or marking requirements, as suffixes often denote visual identifiers rather than electrical changes. Ensure the order specifies the correct reel length if standard spool quantities do not match project needs. Cross-reference the part number with current datasheets to validate availability and manufacturing status before finalizing procurement plans.

Selection Notes

Select this wire when high-temperature resistance and lightweight properties are required in constrained spaces. The 20 AWG gauge suits moderate current applications where flexibility is needed due to the fine 19x32 strand construction. Verify that the 600V rating aligns with system voltage requirements and that the +150°C operating limit meets environmental conditions.

Part Context

This component belongs to the Raychem Spec 55 series of hook-up wires, widely used in aerospace and defense sectors. The 55A0111 designation identifies the base wire type, while the -20 indicates the 20 AWG size. The CS3530 suffix typically defines specific visual characteristics such as jacket color or printing, distinguishing it from other variants in the same electrical family.

Replacement Considerations

Direct replacements must match the 20 AWG size, ETFE insulation material, and tinned copper conductor. Verify that any substitute maintains the same Spec 55 compliance and temperature rating. Suffix differences may require visual inspection to ensure compatibility with existing harness markings or identification protocols.
