TW4122ABNL 10/100 Base-T RJ45 MagJack, Tab Up, Green/ Yellow LED

The TeleWire Technology TW4122ABNL is a 10/100 Base-T EMI-finger shielded RJ45 MagJack with integrated magnetics. Manufactured in Taiwan.

Cross Reference

  • Pulse J3011G21DNL — the TW4122ABNL cross-references to this part.
  • Pulse JB0-1002NL — a further published equivalent on the same footprint.
  • Würth Elektronik 7498010210A — a further published equivalent on the same footprint.

Selection Notes

  • 10/100 Base-T — the transformer inside is specified for this rate.
  • Green/ Yellow LEDs — driven from the host; link and activity mapping is yours.
  • Integrated magnetics — one placement replaces the discrete magnetics and its routing.
  • EMI grounding fingers — chassis bond made at the bezel, not through the PCB.

Typical application: building-control panels and sensor gateways on 10/100 links.

Pricing for the TW4122ABNL ranges from $0.50 to $3.00 USD depending on order quantity and configuration, with volume tiers available on request.

Validate the TW4122ABNL 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 J3011G21DNL?
The TW4122ABNL from TeleWire Technology cross-references to the Pulse J3011G21DNL and to LINK-PP LPJ3011ABNL. 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 TW4122ABNL replace?
The TW4122ABNL cross-references to Pulse J3011G21DNL; Pulse JB0-1002NL; Würth Elektronik 7498010210A, and to LINK-PP LPJ3011ABNL. 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 TW4122ABNL as a second source?
Request a sample of the TW4122ABNL and the mechanical drawing from TeleWire Technology, then check the footprint against the Pulse J3011G21DNL 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.
