TWSK28140AFNL 100/1000 Base-T 2x1 Port RJ45 Jack, Tab Both, Green/ Green LED

The TeleWire Technology TWSK28140AFNL is a 100/1000 Base-T 2x1 EMI-finger shielded RJ45 jack. Manufactured in Taiwan.

Cross Reference

  • Bel Fuse 0879-2G1R-Y6 — the TWSK28140AFNL cross-references to this part.
  • LINK-PP LPJG17039AFNL — same footprint, sourced outside mainland China.

Selection Notes

  • 2x1 port array — 2 ports on one shell, saving panel width.
  • 100/1000 Base-T — the rate the contact geometry is specified to.
  • Green/ Green LEDs — indicated condition set by the host PHY design.
  • −40 °C to +85 °C — the range asked for in outdoor and factory-floor housings.

Typical application: switch and router line cards, where port density per panel inch drives the design.

Pricing for the TWSK28140AFNL ranges from $0.50 to $3.00 USD depending on order quantity and configuration, with volume tiers available on request.

What is a Taiwan-made alternative to the Bel Fuse 0879-2G1R-Y6?
The TWSK28140AFNL from TeleWire Technology cross-references to the Bel Fuse 0879-2G1R-Y6 and to LINK-PP LPJG17039AFNL. 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 TWSK28140AFNL be built to a different configuration?
Yes. The standard TWSK28140AFNL ships with Green/ Green LEDs and latches in both directions. 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 Bel Fuse 0879-2G1R-Y6.
How do I qualify the TWSK28140AFNL as a second source?
Request a sample of the TWSK28140AFNL and the mechanical drawing from TeleWire Technology, then check the footprint against the Bel Fuse 0879-2G1R-Y6 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.
