TW1137GDNL 10/100 Base-T RJ45 MagJack, Tab Down, Yellow/ Green LED

The TeleWire Technology TW1137GDNL is a 10/100 Base-T EMI-finger shielded RJ45 MagJack with integrated magnetics. Manufactured in Taiwan.

Cross Reference

  • Würth Elektronik 7499011122 — the TW1137GDNL cross-references to this part.
  • Würth Elektronik MIC25011-5110T-LF3 — a further published equivalent on the same footprint.
  • LINK-PP LPJ0026GDNL — same footprint, sourced outside mainland China.

Selection Notes

  • 10/100 Base-T — the transformer inside is specified for this rate.
  • Yellow/ Green LEDs — indicated condition set by the host PHY design.
  • Integrated magnetics — one placement replaces the discrete magnetics and its routing.
  • EMI grounding fingers — spring contacts bond the shell to the panel on seating.

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

Pricing for the TW1137GDNL ranges from $0.50 to $3.00 USD depending on order quantity and configuration, with volume tiers available on request.

Validate the TW1137GDNL 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 Würth Elektronik 7499011122?
The TW1137GDNL from TeleWire Technology cross-references to the Würth Elektronik 7499011122 and to LINK-PP LPJ0026GDNL. 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 TW1137GDNL replace?
The TW1137GDNL cross-references to Würth Elektronik 7499011122; Würth Elektronik MIC25011-5110T-LF3, and to LINK-PP LPJ0026GDNL. 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 TW1137GDNL as a second source?
Request a sample of the TW1137GDNL and the mechanical drawing from TeleWire Technology, then check the footprint against the Würth Elektronik 7499011122 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.
