TW28443AWNL 10/100/1000 Base-T RJ45 MagJack, Tab Up, Green/ Green LED

The TeleWire Technology TW28443AWNL is a 10/100/1000 Base-T EMI-finger shielded RJ45 MagJack with integrated magnetics. Manufactured in Taiwan.

Cross Reference

  • Bel Fuse SI-51005-F — the TW28443AWNL cross-references to this part.
  • Bel Fuse SI-51005-FB — a further published equivalent on the same footprint.
  • Bel Fuse SI-51005-G — a further published equivalent on the same footprint.

Selection Notes

  • 10/100/1000 Base-T — matched magnetics for this line rate, no external transformer.
  • Green/ Green LEDs — wired to the host PHY, not to internal logic.
  • Integrated magnetics — isolation and common-mode choke inside the connector, not on the PCB.
  • EMI grounding fingers — spring contacts bond the shell to the panel on seating.

Typical application: single-board computers and SoM carriers taking gigabit off a host PHY.

Pricing for the TW28443AWNL 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 SI-51005-F?
The TW28443AWNL from TeleWire Technology cross-references to the Bel Fuse SI-51005-F and to LINK-PP LPJG17332AWNL. 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 TW28443AWNL replace?
The TW28443AWNL cross-references to Bel Fuse SI-51005-F; Bel Fuse SI-51005-FB; Bel Fuse SI-51005-G, and to LINK-PP LPJG17332AWNL. 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 TW28443AWNL as a second source?
Request a sample of the TW28443AWNL and the mechanical drawing from TeleWire Technology, then check the footprint against the Bel Fuse SI-51005-F 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.
