TWT56519GFNL 2.5G Base-T RJ45 MagJack, Tab Down, Green/ Green LED

The TeleWire Technology TWT56519GFNL is a 2.5G Base-T EMI-finger shielded RJ45 MagJack with integrated magnetics. Manufactured in Taiwan.

Cross Reference

  • Halo HFJ11-E2G48E-L11RL — the TWT56519GFNL cross-references to this part.
  • LINK-PP LPJT4540-8GFNL — same footprint, sourced outside mainland China.

Selection Notes

  • 2.5G Base-T, IEEE 802.3bz — multi-gigabit over installed Cat5e, no recabling.
  • Green/ 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.
  • Integrated magnetics — isolation on all four pairs, short routing to the PHY.

Typical application: industrial gigabit switching in cabinets that see the full temperature swing.

Pricing for the TWT56519GFNL ranges from $0.50 to $3.00 USD depending on order quantity and configuration, with volume tiers available on request.

What is a Taiwan-made alternative to the Halo HFJ11-E2G48E-L11RL?
The TWT56519GFNL from TeleWire Technology cross-references to the Halo HFJ11-E2G48E-L11RL and to LINK-PP LPJT4540-8GFNL. 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 TWT56519GFNL be built to a different configuration?
Yes. The standard TWT56519GFNL ships with Green/ Green LEDs and 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-E2G48E-L11RL.
How do I qualify the TWT56519GFNL as a second source?
Request a sample of the TWT56519GFNL and the mechanical drawing from TeleWire Technology, then check the footprint against the Halo HFJ11-E2G48E-L11RL 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.
