TW7139BGNL 10/100 Base-T RJ45 MagJack, Tab Up, Yellow/ Green LED

The TeleWire Technology TW7139BGNL is a 10/100 Base-T shielded RJ45 MagJack with integrated magnetics. Manufactured in Taiwan.

Cross Reference

  • UDE RTA-143BTK1A — the TW7139BGNL cross-references to this part.
  • LINK-PP LPJ6028BGNL — same footprint, sourced outside mainland China.

Selection Notes

  • 10/100 Base-T — the interface rate the magnetics are matched to.
  • Yellow/ Green LEDs — indicated condition set by the host PHY design.
  • −40 °C to +85 °C — beyond what a commercial-grade jack is rated for.
  • Shielded shell without EMI fingers — shield returns via board ground, not the bezel.

Typical application: process and utility equipment installed in unconditioned plant rooms.

Pricing for the TW7139BGNL ranges from $0.50 to $3.00 USD depending on order quantity and configuration, with volume tiers available on request.

Validate the TW7139BGNL 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 UDE RTA-143BTK1A?
The TW7139BGNL from TeleWire Technology cross-references to the UDE RTA-143BTK1A and to LINK-PP LPJ6028BGNL. 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 TW7139BGNL be built to a different configuration?
Yes. The standard TW7139BGNL ships with Yellow/ 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 UDE RTA-143BTK1A.
How do I qualify the TW7139BGNL as a second source?
Request a sample of the TW7139BGNL and the mechanical drawing from TeleWire Technology, then check the footprint against the UDE RTA-143BTK1A 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.
