TWT16519CNL 2.5G Base-T RJ45 MagJack, Tab Down, No LEDs

The TeleWire Technology TWT16519CNL is a 2.5G Base-T EMI-finger shielded RJ45 MagJack with integrated magnetics. Manufactured in Taiwan.

Cross Reference

  • Halo HFJ11-2G48ERL — the TWT16519CNL cross-references to this part.
  • LINK-PP LPJT0540-8CNL — same footprint, sourced outside mainland China.

Selection Notes

  • 2.5G Base-T, IEEE 802.3bz — the step up from gigabit that reuses the installed plant.
  • No LEDs — no light pipes to align against the panel cut-out.
  • Integrated magnetics — the transformer sits in the shell, freeing board area beside the PHY.
  • EMI grounding fingers — chassis bond made at the bezel, not through the PCB.

Typical application: gigabit industrial switches and embedded controllers carrying the PHY on-board.

Pricing for the TWT16519CNL ranges from $0.50 to $3.00 USD depending on order quantity and configuration, with volume tiers available on request.

Validate the TWT16519CNL 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 HFJ11-2G48ERL?
The TWT16519CNL from TeleWire Technology cross-references to the Halo HFJ11-2G48ERL and to LINK-PP LPJT0540-8CNL. 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 TWT16519CNL be built to a different configuration?
Yes. The standard TWT16519CNL ships with a tab-down 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 HFJ11-2G48ERL.
How do I qualify the TWT16519CNL as a second source?
Request a sample of the TWT16519CNL and the mechanical drawing from TeleWire Technology, then check the footprint against the Halo HFJ11-2G48ERL 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.
