In our This vs. That series, we're comparing (and contrasting) two seemingly similar products. A lot of products seem the same at first glance but can greatly affect the outcome of your next application. Today, we will compare our UL1061 wire and our UL1007 wires. These wires may be the same category of cable, but they have multiple differences that make them unique. After our side by side analysis between these parts, it will be much easier to determine which will be best for your needs and specifications. 

UL1061 wire and UL1007 wire are both UL approved, single-conductor wires commonly used for the internal wiring of electronic equipment. They are both classified as hook-up wire and lead wire, and they’re both similar in size, material, and overall construction. 

UL1061 vs UL1007 Specs for Construction
UL 1061 UL1007
Conductor Size 14-30 AWG 16-32 AWG
Conductor Type Solid or Stranded Solid or Stranded
Conductor Material Bare or Tinned Copper Bare or Tinned Copper
Insulation Thickness .009” (9 mils minimum average thickness, 7 mils minimum thickness at any point.) .016” (15 mils minimum average thickness, 13 mils minimum thickness at any point)
Insulation Material Semi-Rigid Polyvinylchloride (SR-PVC) Polyvinylchloride (PVC)


Both of these wires have solid or stranded copper conductors, which can be bare or tinned, but are made with different insulation materials—UL 1061 comes in SR-PVC and UL1007 comes in PVC insulation, both of which are extruded. The most noticeable construction difference between UL 1061 and UL1007, aside from the insulation material, is the insulation thickness, which affects the overall weight and size.

Electrical Specs

The electrical specifications of  UL1061 and UL1007 don’t vary at all; both have a maximum voltage of 300V and comparable temperature ranges. Both wires also pass the UL VW-1 Flame test. Due to their construction, these hook-up wires can often be found as dual rated with other UL Styles, CSA Styles, and even Mil-Spec styles. Allied Wire and Cable carries the following versions:

UL 1061 UL1007
UL Style UL Style 10002 (105°C) UL Style 1569 (105°C)
CSA Style CSA Type SR-PVC CSA TR-64 (90°C)
Mil-Spec Style Mil-W-16878/1 Type B (105°C, 600V)(depending on size and stranding) N/A

The dual rating can extend some of the specifications of a cable. For example, on the sizes where our UL Style 1007 wire is dual rated with UL 1569, it can be rated to 105°C when used in an application where UL approval is required. When the dual rated UL 1061 wire is used in a mil-spec environment, it rated up to 105°C and 600 volts.

If you are unsure about what cable you’ll need in order to meet the needs of your application, consult with a qualified engineer or with one of Allied’s knowledgeable sales reps. Visit our website to learn more about UL 1061 and UL 1007.
