TWE271GFNL RJ45 Jack, Tab Down, Green/ Green LED

The TeleWire Technology TWE271GFNL is a EMI-finger shielded RJ45 jack. Manufactured in Taiwan.

Cross Reference

  • Halo HFJ11-2450E-L11 — the TWE271GFNL cross-references to this part.
  • Halo HJF11-2450E-L11 — a further published equivalent on the same footprint.
  • LINK-PP LPJE160GFNL — same footprint, sourced outside mainland China.

Selection Notes

  • Green/ Green LEDs — driven from the host; link and activity mapping is yours.
  • −40 °C to +85 °C — beyond what a commercial-grade jack is rated for.
  • No integrated magnetics — pair it with the discrete transformer your PHY vendor specifies.
  • EMI grounding fingers — spring contacts bond the shell to the panel on seating.

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

Pricing for the TWE271GFNL ranges from $0.50 to $3.00 USD depending on order quantity and configuration, with volume tiers available on request.

Validate the TWE271GFNL 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 Halo HFJ11-2450E-L11?
The TWE271GFNL from TeleWire Technology cross-references to the Halo HFJ11-2450E-L11 and to LINK-PP LPJE160GFNL. 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.
Which manufacturers' parts does the TWE271GFNL replace?
The TWE271GFNL cross-references to Halo HFJ11-2450E-L11; Halo HJF11-2450E-L11, and to LINK-PP LPJE160GFNL. TeleWire Technology publishes the full cross-reference so a sourcing engineer can qualify one Taiwan-built part against several incumbents at once.
How do I qualify the TWE271GFNL as a second source?
Request a sample of the TWE271GFNL and the mechanical drawing from TeleWire Technology, then check the footprint against the Halo HFJ11-2450E-L11 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.
