MIL-W-16878/28 is a 260°C high temperature lead wire rated for 1000V AC, featuring tape-wrapped PTFE insulation and a nickel-plated copper conductor. Compliant with NEMA HP-3 Type ET, this heavy-wall aerospace cable delivers exceptional flexibility and bend recovery through its layered tape construction — making it the preferred choice for aircraft wiring harnesses, avionics bays, and defense systems where tight-radius routing and vibration resistance are non-negotiable.
Available in 32–10 AWG with solid and stranded conductor options, M16878/28 combines the voltage headroom of a 1000V class with the thermal endurance of nickel plating, filling a critical niche between 600V medium-wall types and lower-rated mili-tary specifications.
Key Features
260°C high-temperature rating — nickel-plated copper conductor remains stable at temperatures where silver plating oxidizes and degrades 1000V AC heavy-wall dielectric strength — tape-wrapped PTFE provides robust insulation for high-voltage aerospace and defense wiring Superior flexibility & bend recovery — layered tape-wrapped construction conforms to tight-radius bends and springs back without deformation, outperforming extruded types in dynamic routing Vibration-resistant — the multi-layer tape structure dampens mechanical energy, making it ideal for aircraft engine compartments and avionics bays Solder-iron resistant — PTFE insulation survives soldering temperatures without melting, shrinking, or losing dielectric strength for reliable field terminations Chemical inertness — resistant to aviation fuels, hydraulic fluids, de-icing agents, solvents, and hydrocarbons commonly encountered in aerospace environments Broad AWG range — 32–10 AWG covers everything from delicate sensor leads to high-current power feeds, with multi-strand configurations available
M16878/28 vs M16878/27:Selection Guide

Frequently Asked Questions (FAQ)
Q: What is MIL-W-16878/28 wire used for?A: MIL-W-16878/28 is a 260°C high temperature lead wire with tape-wrapped PTFE insulation and nickel-plated copper conductor, rated for 1000V AC. Equivalent to NEMA HP-3 Type ET, it is designed for aerospace and defense applications where flexibility, bend recovery, and vibration resistance are critical — including aircraft engine wiring, avionics bays, and mili-tary ground vehicle systems.
Q: How does M16878/28 differ from M16878/27?A: Both are 1000V heavy-wall types with nickel-plated copper conductors and 260°C ratings. The difference is insulation method: M16878/28 uses tape-wrapped PTFE (better flexibility, superior bend recovery, more vibration resistant), while M16878/27 uses extruded PTFE (better abrasion resistance, superior moisture barrier, stiffer). Select based on your mechanical routing requirements.
Q: Can M16878/28 replace M16878/26?A: Both use nickel-plated copper conductors and tape-wrapped PTFE insulation at 260°C. However, M16878/28 is heavy-wall rated for 1000V, while M16878/26 is medium-wall rated for 600V. They serve different voltage classes and are not direct substitutes unless your system voltage is 600V or below.
Q: What AWG sizes are available for M16878/28?A: MIL-W-16878/28 is available in 32–10 AWG with solid and stranded conductor options, including specialized multi-strand constructions such as 37/26 for the 10 AWG size. Specific strand configurations can be quoted on request.
Q: Is M16878/28 suitable for aircraft engine wiring?A: Yes. The tape-wrapped PTFE insulation flexes around engine contours and recovers its shape after repeated thermal cycling, while the 260°C rating and 1000V dielectric strength meet the demanding requirements of engine harness and APU control wiring.
Q: Can I solder terminations directly to M16878/28?A: Yes. The tape-wrapped PTFE insulation withstands soldering iron temperatures without melting, shrinking, or deforming, ensuring clean and reliable terminations even in field maintenance conditions.
Q: What makes nickel-plated copper better than silver-plated copper for high temperature?A: Nickel plating remains stable at temperatures up to 260°C, whereas silver plating can degrade, oxidize, or migrate at elevated temperatures, leading to increased contact resistance and potential failure. For applications running above 200°C, nickel plating is the preferred conductor finish.
Q: Is M16878/28 RoHS compliant?A: RoHS-compliant options are available. Please confirm your requirement when requesting a quote.
