TW4931GENL 10/100/1000 Base-T RJ45 MagJack, Tab Down, Green/ Yellow LED

The TeleWire Technology TW4931GENL is a 10/100/1000 Base-T EMI-finger shielded RJ45 MagJack with integrated magnetics. Manufactured in Taiwan.

Cross Reference

  • Pulse JXD0-0001NL — the TW4931GENL cross-references to this part.
  • LINK-PP LPJG4820GENL — same footprint, sourced outside mainland China.

Selection Notes

  • 10/100/1000 Base-T — the interface rate the magnetics are matched to.
  • Green/ Yellow LEDs — driven from the host; link and activity mapping is yours.
  • −40 °C to +85 °C — industrial range, not the commercial 0-to-70 grade.
  • Integrated magnetics — isolation on all four pairs, short routing to the PHY.

Typical application: industrial gigabit switching in cabinets that see the full temperature swing.

Pricing for the TW4931GENL ranges from $0.50 to $3.00 USD depending on order quantity and configuration, with volume tiers available on request.

Validate the TW4931GENL 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 JXD0-0001NL?
The TW4931GENL from TeleWire Technology cross-references to the Pulse JXD0-0001NL and to LINK-PP LPJG4820GENL. 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 TW4931GENL replace?
The TW4931GENL cross-references to Pulse JXD0-0001NL; Pulse LPJG4820GENL, and to LINK-PP LPJG4820GENL. 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 TW4931GENL as a second source?
Request a sample of the TW4931GENL and the mechanical drawing from TeleWire Technology, then check the footprint against the Pulse JXD0-0001NL 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.
