TWE3121AHML 1x2 Port RJ45 Jack, Tab Up, Green/ Yellow LED

The TeleWire Technology TWE3121AHML is a 1x2 EMI-finger shielded RJ45 jack. Manufactured in Taiwan.

Cross Reference

  • LINK-PP LPJE201-0AHNL — same footprint, sourced outside mainland China.

Selection Notes

  • 1x2 port array — 2 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 — pair it with the discrete transformer your PHY vendor specifies.

Typical application: multi-port industrial switches where several drops leave through one bezel.

Pricing for the TWE3121AHML ranges from $0.50 to $3.00 USD depending on order quantity and configuration, with volume tiers available on request.

Validate the TWE3121AHML 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 LPJE201-0AHNL?
Yes. The TWE3121AHML from TeleWire Technology is a Taiwan-manufactured equivalent to LINK-PP LPJE201-0AHNL. LINK-PP manufactures in mainland China; the TWE3121AHML is built in Taiwan, which is the reason most buyers cross over to it.
Can the TWE3121AHML be built to a different configuration?
Yes. The standard TWE3121AHML 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 TWE3121AHML as a second source?
Request a sample of the TWE3121AHML and the mechanical drawing from TeleWire Technology, then check the footprint against LINK-PP LPJE201-0AHNL 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.
