TW2J39929BFL 10/100/1000 Base-T 1x2 Port RJ45 MagJack, Tab Up, Green/ Green LED

The TeleWire Technology TW2J39929BFL is a 10/100/1000 Base-T 1x2 shielded RJ45 MagJack with integrated magnetics. Manufactured in Taiwan.

Cross Reference

  • Bel Fuse 0875-1GX2-E3 — the TW2J39929BFL cross-references to this part.
  • LINK-PP LPJG28818BFNL — 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 interface rate the magnetics are matched to.
  • Green/ Green LEDs — wired to the host PHY, not to internal logic.
  • Shielded shell without EMI fingers — grounding becomes a layout decision, not a mechanical one.

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

Pricing for the TW2J39929BFL ranges from $0.50 to $3.00 USD depending on order quantity and configuration, with volume tiers available on request.

Validate the TW2J39929BFL 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 Bel Fuse 0875-1GX2-E3?
The TW2J39929BFL from TeleWire Technology cross-references to the Bel Fuse 0875-1GX2-E3 and to LINK-PP LPJG28818BFNL. 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 TW2J39929BFL be built to a different configuration?
Yes. The standard TW2J39929BFL ships with Green/ 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 0875-1GX2-E3.
How do I qualify the TW2J39929BFL as a second source?
Request a sample of the TW2J39929BFL and the mechanical drawing from TeleWire Technology, then check the footprint against the Bel Fuse 0875-1GX2-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.
