TW2122BBNL 10/100 Base-T RJ45 MagJack, Tab Up, Green/ Yellow LED

The TeleWire Technology TW2122BBNL is a 10/100 Base-T shielded RJ45 MagJack with integrated magnetics. Manufactured in Taiwan.

Cross Reference

  • Pulse J1011F01P — the TW2122BBNL cross-references to this part.
  • Pulse J1011F01PNL — a further published equivalent on the same footprint.
  • Pulse J1011G01P — a further published equivalent on the same footprint.

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.
  • Shielded shell without EMI fingers — shield returns via board ground, not the bezel.
  • Integrated magnetics — isolation on all four pairs, short routing to the PHY.

Typical application: field devices where a 100 Mbit/s drop is the whole network requirement.

Pricing for the TW2122BBNL ranges from $0.50 to $3.00 USD depending on order quantity and configuration, with volume tiers available on request.

Validate the TW2122BBNL 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 Pulse J1011F01P?
The TW2122BBNL from TeleWire Technology cross-references to the Pulse J1011F01P and to LINK-PP LPJ1011BBNL. 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 TW2122BBNL replace?
The TW2122BBNL cross-references to Pulse J1011F01P; Pulse J1011F01PNL; Pulse J1011G01P; Würth Elektronik 7499010214, and to LINK-PP LPJ1011BBNL. 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 TW2122BBNL as a second source?
Request a sample of the TW2122BBNL and the mechanical drawing from TeleWire Technology, then check the footprint against the Pulse J1011F01P 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.
