TWD5122BENL 10/100 Base-T Vertical RJ45 MagJack, Tab Up, Green/ Yellow LED

The TeleWire Technology TWD5122BENL is a 10/100 Base-T shielded RJ45 MagJack with integrated magnetics. Manufactured in Taiwan.

Cross Reference

  • Würth Elektronik 74990101210 — the TWD5122BENL cross-references to this part.
  • LINK-PP LPJD4011BENL — same footprint, sourced outside mainland China.

Selection Notes

  • Vertical (180°) body — the port faces up, away from the board plane.
  • 10/100 Base-T — the transformer inside is specified for this rate.
  • Green/ Yellow LEDs — wired to the host PHY, not to internal logic.
  • −40 °C to +85 °C — industrial range, not the commercial 0-to-70 grade.

Typical application: outdoor and unheated cabinets where the port exits through a top cover.

Pricing for the TWD5122BENL ranges from $0.50 to $3.00 USD depending on order quantity and configuration, with volume tiers available on request.

Validate the TWD5122BENL 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 Würth Elektronik 74990101210?
The TWD5122BENL from TeleWire Technology cross-references to the Würth Elektronik 74990101210 and to LINK-PP LPJD4011BENL. 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 TWD5122BENL be built to a different configuration?
Yes. The standard TWD5122BENL ships with Green/ Yellow 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 Würth Elektronik 74990101210.
How do I qualify the TWD5122BENL as a second source?
Request a sample of the TWD5122BENL and the mechanical drawing from TeleWire Technology, then check the footprint against the Würth Elektronik 74990101210 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.
