TW4JT57049AENL 2.5G Base-T 1x4 Port RJ45 Jack, Tab Down, Green/ Yellow LED

The TeleWire Technology TW4JT57049AENL is a 2.5G Base-T 1x4 EMI-finger shielded RJ45 jack. Manufactured in Taiwan.

Cross Reference

  • LINK-PP LPJM46938AENL-2 — same footprint, sourced outside mainland China.

Selection Notes

  • 1x4 port array — 4 ports on one shell, saving panel width.
  • 2.5G Base-T, IEEE 802.3bz — reaches this rate on existing Cat5e without pulling new cable.
  • Green/ Yellow LEDs — indicated condition set by the host PHY design.
  • −40 °C to +85 °C — industrial range, not the commercial 0-to-70 grade.

Typical application: aggregation blades and multi-port gateways running several links off one PHY bank.

Pricing for the TW4JT57049AENL ranges from $0.50 to $3.00 USD depending on order quantity and configuration, with volume tiers available on request.

Is there a Taiwan-made equivalent to LINK-PP LPJM46938AENL-2?
Yes. The TW4JT57049AENL from TeleWire Technology is a Taiwan-manufactured equivalent to LINK-PP LPJM46938AENL-2. LINK-PP manufactures in mainland China; the TW4JT57049AENL is built in Taiwan, which is the reason most buyers cross over to it.
Can the TW4JT57049AENL be built to a different configuration?
Yes. The standard TW4JT57049AENL ships with Green/ Yellow LEDs and a tab-down 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 TW4JT57049AENL as a second source?
Request a sample of the TW4JT57049AENL and the mechanical drawing from TeleWire Technology, then check the footprint against LINK-PP LPJM46938AENL-2 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.
