Cross Reference

  • Bel Fuse 08C2-1X1T-03 — the TWU5212AONL cross-references to this part.
  • Pulse J6026M51UNL — a further published equivalent on the same footprint.
  • Pulse JY0-0016NL — a further published equivalent on the same footprint.

Selection Notes

  • RJ45 with dual USB — one cut-out carries network and dual USB ports.
  • 10/100 Base-T — the transformer inside is specified for this rate.
  • Green&Orange/ Yellow LEDs — indicated condition set by the host PHY design.
  • Integrated magnetics — one placement replaces the discrete magnetics and its routing.

Typical application: bench and rack equipment that needs a service USB port beside the Ethernet jack.

Pricing for the TWU5212AONL ranges from $0.50 to $3.00 USD depending on order quantity and configuration, with volume tiers available on request.

What is a Taiwan-made alternative to the Bel Fuse 08C2-1X1T-03?
The TWU5212AONL from TeleWire Technology cross-references to the Bel Fuse 08C2-1X1T-03 and to LINK-PP LPJU4101AONL. It is manufactured in Taiwan, giving buyers a supply route outside mainland China for the same footprint. Send the footprint you are designing against and TeleWire Technology will confirm compatibility.
Which manufacturers' parts does the TWU5212AONL replace?
The TWU5212AONL cross-references to Bel Fuse 08C2-1X1T-03; Pulse J6026M51UNL; Pulse JY0-0016NL, and to LINK-PP LPJU4101AONL. TeleWire Technology publishes the full cross-reference so a sourcing engineer can qualify one Taiwan-built part against several incumbents at once.
How do I qualify the TWU5212AONL as a second source?
Request a sample of the TWU5212AONL and the mechanical drawing from TeleWire Technology, then check the footprint against the Bel Fuse 08C2-1X1T-03 on your board. TeleWire Technology builds in Taiwan under an ISO 9001 quality system, and its engineering team will review your drawing before you commit.
