TW2051BBNL 10/100 Base-T RJ45 MagJack, Tab Up, Green/ Yellow LED

The TeleWire Technology TW2051BBNL is a 10/100 Base-T shielded RJ45 MagJack with integrated magnetics. Manufactured in Taiwan.

Cross Reference

  • Hanrun HR963130AE — the TW2051BBNL cross-references to this part.
  • LINK-PP LPJ19401BBNL — same footprint, sourced outside mainland China.

Selection Notes

  • 10/100 Base-T — the interface rate the magnetics are matched to.
  • Green/ Yellow LEDs — driven from the host; link and activity mapping is yours.
  • −40 °C to +85 °C — rated for unheated cabinets across the seasonal swing.
  • Shielded shell without EMI fingers — the shield terminates through the PCB.

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

Pricing for the TW2051BBNL ranges from $0.50 to $3.00 USD depending on order quantity and configuration, with volume tiers available on request.

Validate the TW2051BBNL 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 Hanrun HR963130AE?
The TW2051BBNL from TeleWire Technology cross-references to the Hanrun HR963130AE and to LINK-PP LPJ19401BBNL. 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 TW2051BBNL be built to a different configuration?
Yes. The standard TW2051BBNL 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 Hanrun HR963130AE.
How do I qualify the TW2051BBNL as a second source?
Request a sample of the TW2051BBNL and the mechanical drawing from TeleWire Technology, then check the footprint against the Hanrun HR963130AE 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.
