TWDK1854DNL 10/100/1000 Base-T Vertical RJ45 MagJack, Tab Up, No LEDs

The TeleWire Technology TWDK1854DNL is a 10/100/1000 Base-T shielded RJ45 MagJack with integrated magnetics. Manufactured in Taiwan.

Cross Reference

  • Halo HFJV1-1G11RL — the TWDK1854DNL cross-references to this part.
  • Halo HFJV1-1G41RL — a further published equivalent on the same footprint.
  • LINK-PP LPJD0743DNL — same footprint, sourced outside mainland China.

Selection Notes

  • Vertical (180°) body — the port faces up, away from the board plane.
  • 10/100/1000 Base-T — matched magnetics for this line rate, no external transformer.
  • No LEDs — one fewer tolerance to hold between board and bezel.
  • Shielded shell without EMI fingers — shield returns via board ground, not the bezel.

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

Pricing for the TWDK1854DNL ranges from $0.50 to $3.00 USD depending on order quantity and configuration, with volume tiers available on request.

Validate the TWDK1854DNL 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 Halo HFJV1-1G11RL?
The TWDK1854DNL from TeleWire Technology cross-references to the Halo HFJV1-1G11RL and to LINK-PP LPJD0743DNL. 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 TWDK1854DNL replace?
The TWDK1854DNL cross-references to Halo HFJV1-1G11RL; Halo HFJV1-1G41RL, and to LINK-PP LPJD0743DNL. 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 TWDK1854DNL as a second source?
Request a sample of the TWDK1854DNL and the mechanical drawing from TeleWire Technology, then check the footprint against the Halo HFJV1-1G11RL 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.
