Furukawa Electric's TEX-E is the market-leading triple insulated wire. DAH JIN TLW-B is likewise a triple insulated wire on the same IEC 62368-1 Annex J reinforced-insulation path, certified by UL (file number E236542) and VDE (certificate 40008834) — a verifiable second source for your transformer and power-supply designs.
The table below compares only standards, certification levels and facts DAH JIN can claim for itself; for TEX-E specification data, please refer to Furukawa's official materials — this page does not reproduce them.
| Comparison item | DAH JIN TLW-B | TEX-E（Furukawa Electric） |
|---|---|---|
| Product category | Triple Insulated Wire (TIW) | Triple insulated wire — the market-leading product of the same type |
| Safety-standard path | Winding-wire component capable of the reinforced-insulation level per IEC 62368-1 Annex J / IEC 61558-1 Annex K | Insulated winding wire on the same safety-standard path (see Furukawa's official page) |
| UL | UL certified (per UL 2353, file number E236542, category OBJT2) | Refer to Furukawa's official specifications |
| VDE | VDE certificate 40008834 (covering TLW-B / TLW-BB / TLW-B7S / TLW-F) | Refer to Furukawa's official specifications |
| Conductor diameter range | 0.10–1.00 mm | Refer to Furukawa's official specifications |
| Temperature rating | Class B 130°C; Class F TLW-F (155°C) also available | Refer to Furukawa's official specifications |
| Direct Solderability | Directly solderable (no stripping of outer layers required) | Refer to Furukawa's official specifications |

Equivalence and fitness for use must be confirmed through the buyer's own engineering validation and safety approval.
Fill in the TEX-E part number, wire diameter and annual volume you currently use in the RFQ form, and we will reply within 48 hours with the corresponding TLW-B proposal, specification table and sample arrangements.
Request a Cross-Reference Proposal →A second source is an alternative supplier qualified for the same application alongside your incumbent supplier, spreading the shortage, lead-time and pricing risks of single sourcing. Triple insulated wire is a safety-critical component, and most power-supply makers qualify a second source for it.
TLW-B and TEX-E are both triple insulated wires on the same IEC 62368-1 Annex J / IEC 61558-1 Annex K reinforced-insulation path. Any substitution, however, must be validated in your actual application through engineering and safety approval — we do not claim drop-in equivalence. Instead, we match your TEX-E part number with the corresponding TLW-B size proposal, specification table and samples so you can complete the validation.
Suggested process: (1) compare both specification tables on wire diameter, thermal class and safety requirements; (2) verify DAH JIN's certifications in UL Product iQ (file number E236542) and the VDE database (certificate 40008834); (3) request samples from us and test withstand voltage, solderability and winding-process compatibility in your transformer or power-supply design.
Provide the TEX-E part number, wire diameter and annual volume you currently use via the online RFQ form; we will reply with a cross-reference proposal within 48 hours, and our sales team will arrange samples and lead times once specifications are confirmed.
