TWDK1945BDNL 10/100/1000 Base-T Vertical RJ45 MagJack, Tab Up, Green/ Yellow&Green LED

The TeleWire Technology TWDK1945BDNL is a 10/100/1000 Base-T shielded RJ45 MagJack with integrated magnetics. Manufactured in Taiwan.

Cross Reference

  • Bel Fuse V890-1AX1-A1 — the TWDK1945BDNL cross-references to this part.
  • Pulse JD3-0002NL — a further published equivalent on the same footprint.
  • X Multiple XMV-J1N521ZJE — a further published equivalent on the same footprint.

Selection Notes

  • Vertical (180°) body — the port faces up, away from the board plane.
  • 10/100/1000 Base-T — the rate the internal transformer is wound for.
  • Green/ Yellow&Green LEDs — wired to the host PHY, not to internal logic.
  • Shielded shell without EMI fingers — grounding becomes a layout decision, not a mechanical one.

Typical application: compact industrial controllers where the Ethernet port exits through a top cover.

Pricing for the TWDK1945BDNL ranges from $0.50 to $3.00 USD depending on order quantity and configuration, with volume tiers available on request.

Validate the TWDK1945BDNL on your board first. Samples are available for design validation, and the mechanical drawing gives the footprint before you commit a layout. Request a sample or quotation.

What is a Taiwan-made alternative to the Bel Fuse V890-1AX1-A1?
The TWDK1945BDNL from TeleWire Technology cross-references to the Bel Fuse V890-1AX1-A1 and to LINK-PP LPJD0834BDNL. 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 TWDK1945BDNL replace?
The TWDK1945BDNL cross-references to Bel Fuse V890-1AX1-A1; Pulse JD3-0002NL; X Multiple XMV-J1N521ZJE, and to LINK-PP LPJD0834BDNL. 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 TWDK1945BDNL as a second source?
Request a sample of the TWDK1945BDNL and the mechanical drawing from TeleWire Technology, then check the footprint against the Bel Fuse V890-1AX1-A1 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.
