UL1671 300 V 150 °C Fluoropolymer Hook-Up Wire

UL1671 is a Fluoropolymer-insulated hook-up wire manufactured by Xinya Electronic Co., Ltd. It is rated 300 V, 150 °C. It is supplied in 18 recorded constructions spanning 20–32 AWG, with an overall diameter of 0.71–1.47 mm, cut to the length you order.

UL1671 at a glance

• 20–32 AWG, across 18 listed constructions
• Both solid (single-strand) and stranded conductors are listed — 4 solid and 14 stranded
• Insulation wall 0.254 mm
• Overall diameter 0.71–1.47 mm
• Max. conductor resistance 36.7–595 Ω/km at 20 °C DC (roughly 11.2–181.4 Ω per 1,000 ft)
• Routine withstand test on every listed row: 2000 VAC, 1 min

How UL1671 compares with its nearest alternatives

UL1671 and UL1333 share the 300 V rating and 150 °C temperature rating. Overall diameter runs 0.71–1.47 mm for UL1671 against 0.96–3.04 mm for UL1333. UL1671 is the tighter of the two where harness space is limited. Insulation wall is 0.254 mm against 0.33 mm. Size coverage is 20–32 AWG against 12–30 AWG.

UL1671 and UL10086 share the 150 °C temperature rating and Fluoropolymer insulation. The distinction is in voltage rating (300 V against 600 V). Insulation wall is 0.254 mm against 0.26 mm.

Conductor construction and selection

Both conductor families are listed. Single-strand rows such as 1/0.20 at 32 AWG suit fixed routing and insulation-displacement termination, where the conductor is not flexed after installation. Stranded rows such as 7/0.08 at 32 AWG flex repeatedly and are the usual choice for hand-soldered harnesses and anything that has to follow a moving path. Conductor resistance is the same at a given size, so the choice between them is mechanical rather than electrical.

How to read the UL1671 table

“Insulation O.D. (mm)” is measured over the insulation, not over a jacket, tape or braid. Conductor resistance is stated at 20 °C DC per kilometre — divide by 3.281 for ohms per 1,000 ft. The withstand column is a routine production test applied to finished lengths, not a continuous working voltage.

Questions buyers ask about UL1671

Which sizes of UL1671 are available?

20–32 AWG, across the 18 constructions in the table below. Sizes outside the table can be quoted on request.

Can UL1671 be supplied in both solid and stranded conductor?

Yes. The documented range covers 18 constructions, of which 4 are single-strand and 14 are stranded. Give the construction, not only the AWG, when you request a quotation.

What overall diameter does UL1671 run to?

The documented range is 0.71–1.47 mm. Quote the size, not the style alone, when the diameter has to fit a specific gland, grommet or channel.
