TWDK1837DNL 10/100/1000 Base-T Vertical RJ45 MagJack, Tab Up, No LEDs

The TeleWire Technology TWDK1837DNL is a 10/100/1000 Base-T shielded RJ45 MagJack with integrated magnetics. Manufactured in Taiwan.

Cross Reference

  • Halo HFJV1-1G11RL — the TWDK1837DNL cross-references to this part.
  • LINK-PP LPJD0726DNL — same footprint, sourced outside mainland China.

Selection Notes

  • 10/100/1000 Base-T — the transformer inside is specified for this rate.
  • No LEDs — the full front aperture stays clear for the mating plug.
  • Shielded shell without EMI fingers — grounding becomes a layout decision, not a mechanical one.
  • Integrated magnetics — one placement replaces the discrete magnetics and its routing.

Typical application: DIN-rail modules whose width is fixed and whose depth is not.

Pricing for the TWDK1837DNL ranges from $0.50 to $3.00 USD depending on order quantity and configuration, with volume tiers available on request.

Validate the TWDK1837DNL 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 TWDK1837DNL from TeleWire Technology cross-references to the Halo HFJV1-1G11RL and to LINK-PP LPJD0726DNL. 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 TWDK1837DNL be built to a different configuration?
Yes. The standard TWDK1837DNL ships with 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 HFJV1-1G11RL.
How do I qualify the TWDK1837DNL as a second source?
Request a sample of the TWDK1837DNL 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.
