TWD6122BFNL 10/100 Base-T Vertical RJ45 MagJack, Tab Up, Green/ Green LED

The TeleWire Technology TWD6122BFNL is a 10/100 Base-T shielded RJ45 MagJack with integrated magnetics. Manufactured in Taiwan.

Cross Reference

  • Halo HFJV1-E2450-L11RL — the TWD6122BFNL cross-references to this part.
  • LINK-PP LPJD5011BFNL — same footprint, sourced outside mainland China.

Selection Notes

  • Vertical (180°) body — cable exits perpendicular to the PCB, not over its edge.
  • 10/100 Base-T — matched magnetics for this line rate, no external transformer.
  • Green/ Green LEDs — wired to the host PHY, not to internal logic.
  • −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 TWD6122BFNL ranges from $0.50 to $3.00 USD depending on order quantity and configuration, with volume tiers available on request.

Validate the TWD6122BFNL 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-E2450-L11RL?
The TWD6122BFNL from TeleWire Technology cross-references to the Halo HFJV1-E2450-L11RL and to LINK-PP LPJD5011BFNL. 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 TWD6122BFNL be built to a different configuration?
Yes. The standard TWD6122BFNL ships with Green/ 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-E2450-L11RL.
How do I qualify the TWD6122BFNL as a second source?
Request a sample of the TWD6122BFNL and the mechanical drawing from TeleWire Technology, then check the footprint against the Halo HFJV1-E2450-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.
