TW1122BBNL 10/100 Base-T RJ45 MagJack, Tab Down, Green/ Yellow LED

The TeleWire Technology TW1122BBNL is a 10/100 Base-T shielded RJ45 MagJack with integrated magnetics. Manufactured in Taiwan.

Cross Reference

  • Bel Fuse SI-60141-F — the TW1122BBNL cross-references to this part.
  • Bothhand LU1S041F-43LF — a further published equivalent on the same footprint.
  • Pulse J00-0045NL — 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 — grounding becomes a layout decision, not a mechanical one.
  • 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 TW1122BBNL ranges from $0.50 to $3.00 USD depending on order quantity and configuration, with volume tiers available on request.

Validate the TW1122BBNL 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 Bel Fuse SI-60141-F?
The TW1122BBNL from TeleWire Technology cross-references to the Bel Fuse SI-60141-F and to LINK-PP LPJ0011BBNL. 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 TW1122BBNL replace?
The TW1122BBNL cross-references to Bel Fuse SI-60141-F; Bothhand LU1S041F-43LF; Pulse J00-0045NL; Pulse J0011D01B; Pulse J0011D01BNL; Pulse JKM-0009NL, and to LINK-PP LPJ0011BBNL. 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 TW1122BBNL as a second source?
Request a sample of the TW1122BBNL and the mechanical drawing from TeleWire Technology, then check the footprint against the Bel Fuse SI-60141-F 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.
