TW1914HENL 10/100/1000 Base-T RJ45 MagJack, Tab Down, Green/ Yellow LED

The TeleWire Technology TW1914HENL is a 10/100/1000 Base-T shielded RJ45 MagJack with integrated magnetics. Manufactured in Taiwan.

Cross Reference

  • UDE RB1-946BAK1A — the TW1914HENL cross-references to this part.
  • LINK-PP LPJG0803HENL — same footprint, sourced outside mainland China.

Selection Notes

  • 10/100/1000 Base-T — matched magnetics for this line rate, no external transformer.
  • Green/ Yellow LEDs — wired to the host PHY, not to internal logic.
  • Shielded shell without EMI fingers — shield returns via board ground, not the bezel.
  • Integrated magnetics — isolation and common-mode choke inside the connector, not on the PCB.

Typical application: gigabit industrial switches and embedded controllers carrying the PHY on-board.

Pricing for the TW1914HENL ranges from $0.50 to $3.00 USD depending on order quantity and configuration, with volume tiers available on request.

Validate the TW1914HENL 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 RB1-946BAK1A?
The TW1914HENL from TeleWire Technology cross-references to the UDE RB1-946BAK1A and to LINK-PP LPJG0803HENL. 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 TW1914HENL be built to a different configuration?
Yes. The standard TW1914HENL ships with Green/ Yellow 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 UDE RB1-946BAK1A.
How do I qualify the TW1914HENL as a second source?
Request a sample of the TW1914HENL and the mechanical drawing from TeleWire Technology, then check the footprint against the UDE RB1-946BAK1A 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.
