TW2J39929A41NL 10/100/1000 Base-T 1x2 Port RJ45 MagJack, Tab Up, Green/ Yellow&Green LED

The TeleWire Technology TW2J39929A41NL is a 10/100/1000 Base-T 1x2 EMI-finger shielded RJ45 MagJack with integrated magnetics. Manufactured in Taiwan.

Cross Reference

  • Bel Fuse 0875-1L2T-E3 — the TW2J39929A41NL cross-references to this part.
  • LINK-PP LPJG28818A30NL — same footprint, sourced outside mainland China.

Selection Notes

  • 1x2 port array — 2 ports on one shell, saving panel width.
  • 10/100/1000 Base-T — the transformer inside is specified for this rate.
  • Green/ Yellow&Green LEDs — wired to the host PHY, not to internal logic.
  • Integrated magnetics — one placement replaces the discrete magnetics and its routing.

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

Pricing for the TW2J39929A41NL 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 0875-1L2T-E3?
The TW2J39929A41NL from TeleWire Technology cross-references to the Bel Fuse 0875-1L2T-E3 and to LINK-PP LPJG28818A30NL. 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 TW2J39929A41NL be built to a different configuration?
Yes. The standard TW2J39929A41NL ships with Green/ Yellow&Green 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, while holding the footprint that matches Bel Fuse 0875-1L2T-E3.
How do I qualify the TW2J39929A41NL as a second source?
Request a sample of the TW2J39929A41NL and the mechanical drawing from TeleWire Technology, then check the footprint against the Bel Fuse 0875-1L2T-E3 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.
