TWE5121AHNL 1x4 Port RJ45 Jack, Tab Up, Green/ Yellow LED

The TeleWire Technology TWE5121AHNL is a 1x4 EMI-finger shielded RJ45 jack. Manufactured in Taiwan.

Cross Reference

  • LINK-PP LPJE401-0AHNL — same footprint, sourced outside mainland China.

Selection Notes

  • 1x4 port array — 4 ports on one shell, saving panel width.
  • Green/ Yellow LEDs — driven from the host; link and activity mapping is yours.
  • −40 °C to +85 °C — rated for unheated cabinets across the seasonal swing.
  • No integrated magnetics — isolation sits on the PCB, so the magnetics choice stays yours.

Typical application: patching and distribution boards that group ports behind a single opening.

Pricing for the TWE5121AHNL ranges from $0.50 to $3.00 USD depending on order quantity and configuration, with volume tiers available on request.

Validate the TWE5121AHNL 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 LPJE401-0AHNL?
Yes. The TWE5121AHNL from TeleWire Technology is a Taiwan-manufactured equivalent to LINK-PP LPJE401-0AHNL. LINK-PP manufactures in mainland China; the TWE5121AHNL is built in Taiwan, which is the reason most buyers cross over to it.
Can the TWE5121AHNL be built to a different configuration?
Yes. The standard TWE5121AHNL 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 TWE5121AHNL as a second source?
Request a sample of the TWE5121AHNL and the mechanical drawing from TeleWire Technology, then check the footprint against LINK-PP LPJE401-0AHNL 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.
