TWD2122BFNL 10/100 Base-T Vertical RJ45 MagJack, Tab Up, Green/ Green LED

The TeleWire Technology TWD2122BFNL is a 10/100 Base-T shielded RJ45 MagJack with integrated magnetics. Manufactured in Taiwan.

Cross Reference

  • Halo HFJV1-2450-L11RL — the TWD2122BFNL cross-references to this part.
  • TE Connectivity 1840419-1 — a further published equivalent on the same footprint.
  • LINK-PP LPJD1011BFNL — same footprint, sourced outside mainland China.

Selection Notes

  • Vertical (180°) body — the plug seats vertically, keeping the board edge clear.
  • 10/100 Base-T — the rate the internal transformer is wound for.
  • Green/ Green LEDs — driven from the host; link and activity mapping is yours.
  • Shielded shell without EMI fingers — the shield terminates through the PCB.

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

Pricing for the TWD2122BFNL ranges from $0.50 to $3.00 USD depending on order quantity and configuration, with volume tiers available on request.

Validate the TWD2122BFNL 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 HFJV1-2450-L11RL?
The TWD2122BFNL from TeleWire Technology cross-references to the Halo HFJV1-2450-L11RL and to LINK-PP LPJD1011BFNL. 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 TWD2122BFNL replace?
The TWD2122BFNL cross-references to Halo HFJV1-2450-L11RL; TE Connectivity 1840419-1, and to LINK-PP LPJD1011BFNL. 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 TWD2122BFNL as a second source?
Request a sample of the TWD2122BFNL and the mechanical drawing from TeleWire Technology, then check the footprint against the Halo HFJV1-2450-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.
