TW1912GENL 10/100/1000 Base-T RJ45 MagJack, Tab Down, Green/ Yellow LED

The TeleWire Technology TW1912GENL is a 10/100/1000 Base-T EMI-finger shielded RJ45 MagJack with integrated magnetics. Manufactured in Taiwan.

Cross Reference

  • UDE RB1-215BAM1A — the TW1912GENL cross-references to this part.
  • UDE RD1-215BAM1A — a further published equivalent on the same footprint.
  • UDE RDA-215BAM1A — a further published equivalent on the same footprint.

Selection Notes

  • 10/100/1000 Base-T — the interface rate the magnetics are matched to.
  • Green/ Yellow LEDs — indicated condition set by the host PHY design.
  • Integrated magnetics — isolation on all four pairs, short routing to the PHY.
  • EMI grounding fingers — chassis bond made at the bezel, not through the PCB.

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

Pricing for the TW1912GENL ranges from $0.50 to $3.00 USD depending on order quantity and configuration, with volume tiers available on request.

Validate the TW1912GENL 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 RB1-215BAM1A?
The TW1912GENL from TeleWire Technology cross-references to the UDE RB1-215BAM1A and to LINK-PP LPJG0801GENL. 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.
Which manufacturers' parts does the TW1912GENL replace?
The TW1912GENL cross-references to UDE RB1-215BAM1A; UDE RD1-215BAM1A; UDE RDA-215BAM1A; Würth Elektronik 7499111211; Würth Elektronik MIC38013-0155T-LF3; YDS 48F-01GYD2NL, and to LINK-PP LPJG0801GENL. TeleWire Technology publishes the full cross-reference so a sourcing engineer can qualify one Taiwan-built part against several incumbents at once.
How do I qualify the TW1912GENL as a second source?
Request a sample of the TW1912GENL and the mechanical drawing from TeleWire Technology, then check the footprint against the UDE RB1-215BAM1A 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.
