TW27437AENL 10/100/1000 Base-T RJ45 MagJack, Tab Up, Green/ Yellow LED

The TeleWire Technology TW27437AENL is a 10/100/1000 Base-T EMI-finger shielded RJ45 MagJack with integrated magnetics. Manufactured in Taiwan.

Cross Reference

  • Halo HFJT1-1G11-L12RL — the TW27437AENL cross-references to this part.
  • LINK-PP LPJG16326AENL — same footprint, sourced outside mainland China.

Selection Notes

  • 10/100/1000 Base-T — the rate the internal transformer is wound for.
  • Green/ Yellow LEDs — indicated condition set by the host PHY design.
  • Integrated magnetics — the transformer sits in the shell, freeing board area beside the PHY.
  • EMI grounding fingers — chassis bond made at the bezel, not through the PCB.

Typical application: single-board computers and SoM carriers taking gigabit off a host PHY.

Pricing for the TW27437AENL ranges from $0.50 to $3.00 USD depending on order quantity and configuration, with volume tiers available on request.

Validate the TW27437AENL 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 Halo HFJT1-1G11-L12RL?
The TW27437AENL from TeleWire Technology cross-references to the Halo HFJT1-1G11-L12RL and to LINK-PP LPJG16326AENL. 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.
Can the TW27437AENL be built to a different configuration?
Yes. The standard TW27437AENL ships with Green/ Yellow LEDs and a tab-up latch. TeleWire Technology can change LED colour, latch direction, contact plating thickness (Gold Flash through 50 microinch) and tray or reel packaging against your drawing, while holding the footprint that matches Halo HFJT1-1G11-L12RL.
How do I qualify the TW27437AENL as a second source?
Request a sample of the TW27437AENL and the mechanical drawing from TeleWire Technology, then check the footprint against the Halo HFJT1-1G11-L12RL 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.
