TW275045AENL 2.5G Base-T RJ45 MagJack, Tab Up, Green/ Yellow LED

The TeleWire Technology TW275045AENL is a 2.5G Base-T EMI-finger shielded RJ45 MagJack with integrated magnetics. Manufactured in Taiwan.

Cross Reference

  • LINK-PP LPJG164934AENL — same footprint, sourced outside mainland China.

Selection Notes

  • 2.5G Base-T, IEEE 802.3bz — reaches this rate on existing Cat5e without pulling new cable.
  • Green/ Yellow LEDs — wired to the host PHY, not to internal logic.
  • −40 °C to +85 °C — beyond what a commercial-grade jack is rated for.
  • 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 TW275045AENL ranges from $0.50 to $3.00 USD depending on order quantity and configuration, with volume tiers available on request.

Validate the TW275045AENL 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.

Is there a Taiwan-made equivalent to LINK-PP LPJG164934AENL?
Yes. The TW275045AENL from TeleWire Technology is a Taiwan-manufactured equivalent to LINK-PP LPJG164934AENL. LINK-PP manufactures in mainland China; the TW275045AENL is built in Taiwan, which is the reason most buyers cross over to it.
Can the TW275045AENL be built to a different configuration?
Yes. The standard TW275045AENL 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. Send the drawing you are designing against and the engineering team will confirm what is achievable.
How do I qualify the TW275045AENL as a second source?
Request a sample of the TW275045AENL and the mechanical drawing from TeleWire Technology, then check the footprint against LINK-PP LPJG164934AENL 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.
