TWDK5854B41NL 10/100/1000 Base-T Vertical RJ45 MagJack, Tab Up, Green/ Yellow&Green LED

The TeleWire Technology TWDK5854B41NL is a 10/100/1000 Base-T shielded RJ45 MagJack with integrated magnetics. Manufactured in Taiwan.

Cross Reference

  • Halo HFJV1-E1G41-L51RL — the TWDK5854B41NL cross-references to this part.
  • LINK-PP LPJD4743B30NL — same footprint, sourced outside mainland China.

Selection Notes

  • Vertical (180°) body — cable exits perpendicular to the PCB, not over its edge.
  • 10/100/1000 Base-T — the interface rate the magnetics are matched to.
  • Green/ Yellow&Green LEDs — driven from the host; link and activity mapping is yours.
  • −40 °C to +85 °C — rated for unheated cabinets across the seasonal swing.

Typical application: outdoor and unheated cabinets where the port exits through a top cover.

Pricing for the TWDK5854B41NL ranges from $0.50 to $3.00 USD depending on order quantity and configuration, with volume tiers available on request.

Validate the TWDK5854B41NL 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-E1G41-L51RL?
The TWDK5854B41NL from TeleWire Technology cross-references to the Halo HFJV1-E1G41-L51RL and to LINK-PP LPJD4743B30NL. 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.
Can the TWDK5854B41NL be built to a different configuration?
Yes. The standard TWDK5854B41NL ships with Green/ Yellow&Green LEDs and a tab-up latch. TeleWire Technology can change LED colour, latch direction, contact plating thickness (Gold Flash through 50 microinch) and tray or reel packaging against your drawing, while holding the footprint that matches Halo HFJV1-E1G41-L51RL.
How do I qualify the TWDK5854B41NL as a second source?
Request a sample of the TWDK5854B41NL and the mechanical drawing from TeleWire Technology, then check the footprint against the Halo HFJV1-E1G41-L51RL 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.
