TWL8112BINL 10/100 Base-T Low-Profile RJ45 MagJack, Tab Up, Yellow&Green/ Green LED

The TeleWire Technology TWL8112BINL is a 10/100 Base-T shielded RJ45 MagJack with integrated magnetics. Manufactured in Taiwan.

Cross Reference

  • Bel Fuse L829-1KX1-91 — the TWL8112BINL cross-references to this part.
  • LINK-PP LPJK7001BINL — same footprint, sourced outside mainland China.

Selection Notes

  • Low-profile body — reduced height where board-to-lid clearance is the constraint.
  • 10/100 Base-T — the transformer inside is specified for this rate.
  • Yellow&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: slim gateways and rack sleds where enclosure height is the binding constraint.

Pricing for the TWL8112BINL ranges from $0.50 to $3.00 USD depending on order quantity and configuration, with volume tiers available on request.

Validate the TWL8112BINL 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 L829-1KX1-91?
The TWL8112BINL from TeleWire Technology cross-references to the Bel Fuse L829-1KX1-91 and to LINK-PP LPJK7001BINL. 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 TWL8112BINL be built to a different configuration?
Yes. The standard TWL8112BINL ships with Yellow&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 L829-1KX1-91.
How do I qualify the TWL8112BINL as a second source?
Request a sample of the TWL8112BINL and the mechanical drawing from TeleWire Technology, then check the footprint against the Bel Fuse L829-1KX1-91 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.
