TWSK28148A5NL 100/1000 Base-T 2x1 Port RJ45 Jack, Tab Both, Yellow&Green/ Yellow&Green LED

The TeleWire Technology TWSK28148A5NL is a 100/1000 Base-T 2x1 EMI-finger shielded RJ45 jack. Manufactured in Taiwan.

Cross Reference

  • Bel Fuse 0879-2C1R-54 — the TWSK28148A5NL cross-references to this part.
  • LINK-PP LPJG17037A4NL — 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.
  • Yellow&Green/ Yellow&Green LEDs — wired to the host PHY, not to internal logic.
  • −40 °C to +85 °C — industrial range, not the commercial 0-to-70 grade.

Typical application: aggregation blades and multi-port gateways running several links off one PHY bank.

Pricing for the TWSK28148A5NL 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 0879-2C1R-54?
The TWSK28148A5NL from TeleWire Technology cross-references to the Bel Fuse 0879-2C1R-54 and to LINK-PP LPJG17037A4NL. 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 TWSK28148A5NL be built to a different configuration?
Yes. The standard TWSK28148A5NL ships with Yellow&Green/ Yellow&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 0879-2C1R-54.
How do I qualify the TWSK28148A5NL as a second source?
Request a sample of the TWSK28148A5NL and the mechanical drawing from TeleWire Technology, then check the footprint against the Bel Fuse 0879-2C1R-54 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.
