TWE291XDNL RJ45 Jack, Tab Down, No LEDs

The TeleWire Technology TWE291XDNL is a shielded RJ45 jack. Manufactured in Taiwan.

Cross Reference

  • Würth Elektronik 615008140121 — the TWE291XDNL cross-references to this part.
  • LINK-PP LPJEF180XDNL — same footprint, sourced outside mainland China.

Selection Notes

  • −40 °C to +85 °C — rated for unheated cabinets across the seasonal swing.
  • No LEDs — the full front aperture stays clear for the mating plug.
  • Shielded shell without EMI fingers — the shield terminates through the PCB.
  • No integrated magnetics — isolation sits on the PCB, so the magnetics choice stays yours.

Typical application: process and utility equipment installed in unconditioned plant rooms.

Pricing for the TWE291XDNL ranges from $0.50 to $3.00 USD depending on order quantity and configuration, with volume tiers available on request.

Validate the TWE291XDNL 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 Würth Elektronik 615008140121?
The TWE291XDNL from TeleWire Technology cross-references to the Würth Elektronik 615008140121 and to LINK-PP LPJEF180XDNL. 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.
Can the TWE291XDNL be built to a different configuration?
Yes. The standard TWE291XDNL ships with 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, while holding the footprint that matches Würth Elektronik 615008140121.
How do I qualify the TWE291XDNL as a second source?
Request a sample of the TWE291XDNL and the mechanical drawing from TeleWire Technology, then check the footprint against the Würth Elektronik 615008140121 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.
