TW1137BBNL 10/100 Base-T RJ45 MagJack, Tab Down, Green/ Yellow LED

The TeleWire Technology TW1137BBNL is a 10/100 Base-T shielded RJ45 MagJack with integrated magnetics. Manufactured in Taiwan.

Cross Reference

  • Amphenol LMJ30288115CNL — the TW1137BBNL cross-references to this part.
  • Bel Fuse SI-60216-F — a further published equivalent on the same footprint.
  • Pulse J0026D01BNL — a further published equivalent on the same footprint.

Selection Notes

  • 10/100 Base-T — the rate the internal transformer is wound for.
  • 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 — the transformer sits in the shell, freeing board area beside the PHY.

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

Pricing for the TW1137BBNL ranges from $0.50 to $3.00 USD depending on order quantity and configuration, with volume tiers available on request.

Validate the TW1137BBNL 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 Amphenol LMJ30288115CNL?
The TW1137BBNL from TeleWire Technology cross-references to the Amphenol LMJ30288115CNL and to LINK-PP LPJ0026BBNL. 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 TW1137BBNL replace?
The TW1137BBNL cross-references to Amphenol LMJ30288115CNL; Bel Fuse SI-60216-F; Pulse J0026D01BNL, and to LINK-PP LPJ0026BBNL. 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 TW1137BBNL as a second source?
Request a sample of the TW1137BBNL and the mechanical drawing from TeleWire Technology, then check the footprint against the Amphenol LMJ30288115CNL 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.
