TW1912GBNL 10/100/1000 Base-T RJ45 MagJack, Tab Down, Green/ Yellow LED

The TeleWire Technology TW1912GBNL is a 10/100/1000 Base-T EMI-finger shielded RJ45 MagJack with integrated magnetics. Manufactured in Taiwan.

Cross Reference

  • YDS 48F-01GYD2P2NL — the TW1912GBNL cross-references to this part.
  • LINK-PP LPJG0801GBNL — 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.
  • Integrated magnetics — isolation and common-mode choke inside the connector, not on the PCB.
  • EMI grounding fingers — shield path closes against the chassis bezel.

Typical application: single-board computers and SoM carriers taking gigabit off a host PHY.

Pricing for the TW1912GBNL ranges from $0.50 to $3.00 USD depending on order quantity and configuration, with volume tiers available on request.

Validate the TW1912GBNL 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 YDS 48F-01GYD2P2NL?
The TW1912GBNL from TeleWire Technology cross-references to the YDS 48F-01GYD2P2NL and to LINK-PP LPJG0801GBNL. 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 TW1912GBNL be built to a different configuration?
Yes. The standard TW1912GBNL 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 YDS 48F-01GYD2P2NL.
How do I qualify the TW1912GBNL as a second source?
Request a sample of the TW1912GBNL and the mechanical drawing from TeleWire Technology, then check the footprint against the YDS 48F-01GYD2P2NL 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.
