Allied Encyclopedia: M16878/4 vs. M16878/5 vs. M16878/6

Allied EncyclopediaM16878/4, M16878/5, and M16878/6 are all types of PTFE Coated Hook Up Wire. When you compare the different slant sheets, you can see they share many similarities. But there are also some notable differences to consider before selecting the wire for your application.

All have excellent resistance to thermal aging, solder damage, flame, and moisture, and are designed to withstand even the harshest conditions. M16878 Wire is ideal for high frequency and high temperature applications. These wires feature silver plated copper conductors and are rated for temperatures between -60°C and +200°C.

PTFE insulation offers high resistance to ultra-violet radiation, stress, chemicals, and mold growth. It also provides a smaller, lighter construction compared to hook up and lead wire with other insulation types.

M16878 Hook Up Wire follows NEMA standards for PTFE insulated wire. NEMA HP3 Type E, Type EE, and Type ET have technically replaced Mil-W-16878/4, Mil-W-16878/5, and Mil-W-16878/6 standards, but the mil-spec numbers are still widely used in the industry to refer to these products.

While these cables share many advantages, their differences must be considered in order to find which part best suits your needs.

M16878/4 (NEMA HP3 Type E) has a nominal wall thickness of .010 inches, and is suitable for use at a maximum of 600 volts RMS.

M16878/5 (NEMA HP3 Type EE) has thicker insulation than M16878/4 wire. It has a nominal wall thickness of .015 inches. With thicker insulation, comes the ability to operate at higher voltages. Of the cables discussed in this article, M16878/5 has the thickest insulation, and the highest voltage rating at 1000 volts RMS.

M16878/6 (NEMA HP3 Type ET) has a nominal wall of .005 inches, the thinnest of the three wires. It also has the lowest voltage rating at 250 volts RMS. Because M16878/6 features such thin wall insulation that can be fragile and easily damaged, this wire is not recommended for use in abrasive environments or where mechanical stress may be a concern.

Ultimately, M16878/4 cable, M16878/5 cable, and M16878/6 cable share a lot of the same benefits, but you must take a close look at the voltage requirements and other parameters of your application to determine which is right for you.
