TW1137A84NL 10/100 Base-T RJ45 MagJack, Tab Down, Green/ Yellow LED

The TeleWire Technology TW1137A84NL is a 10/100 Base-T EMI-finger shielded RJ45 MagJack with integrated magnetics. Manufactured in Taiwan.

Cross Reference

  • Pulse J0026D21F — the TW1137A84NL cross-references to this part.
  • Pulse J0026D21FNL — a further published equivalent on the same footprint.
  • LINK-PP LPJ0026A73NL — same footprint, sourced outside mainland China.

Selection Notes

  • 10/100 Base-T — the rate the internal transformer is wound for.
  • Green/ Yellow LEDs — wired to the host PHY, not to internal logic.
  • Integrated magnetics — the transformer sits in the shell, freeing board area beside the PHY.
  • EMI grounding fingers — shield path closes against the chassis bezel.

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

Pricing for the TW1137A84NL ranges from $0.50 to $3.00 USD depending on order quantity and configuration, with volume tiers available on request.

Validate the TW1137A84NL 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 J0026D21F?
The TW1137A84NL from TeleWire Technology cross-references to the Pulse J0026D21F and to LINK-PP LPJ0026A73NL. 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 TW1137A84NL replace?
The TW1137A84NL cross-references to Pulse J0026D21F; Pulse J0026D21FNL, and to LINK-PP LPJ0026A73NL. 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 TW1137A84NL as a second source?
Request a sample of the TW1137A84NL and the mechanical drawing from TeleWire Technology, then check the footprint against the Pulse J0026D21F 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.
