TW1125ABNL 10/100 Base-T RJ45 MagJack, Tab Down, Green/ Yellow LED

The TeleWire Technology TW1125ABNL is a 10/100 Base-T EMI-finger shielded RJ45 MagJack with integrated magnetics. Manufactured in Taiwan.

Cross Reference

  • Bothhand KLU1T031C-43 — the TW1125ABNL cross-references to this part.
  • Bothhand KLU1T041C-43 LF — a further published equivalent on the same footprint.
  • LINK-PP LPJ0014ABNL — same footprint, sourced outside mainland China.

Selection Notes

  • 10/100 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 — chassis bond made at the bezel, not through the PCB.

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

Pricing for the TW1125ABNL ranges from $0.50 to $3.00 USD depending on order quantity and configuration, with volume tiers available on request.

Validate the TW1125ABNL 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 Bothhand KLU1T031C-43?
The TW1125ABNL from TeleWire Technology cross-references to the Bothhand KLU1T031C-43 and to LINK-PP LPJ0014ABNL. 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 TW1125ABNL replace?
The TW1125ABNL cross-references to Bothhand KLU1T031C-43; Bothhand KLU1T041C-43 LF, and to LINK-PP LPJ0014ABNL. 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 TW1125ABNL as a second source?
Request a sample of the TW1125ABNL and the mechanical drawing from TeleWire Technology, then check the footprint against the Bothhand KLU1T031C-43 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.
