TWL81510A09NLV 10/100 Base-T Low-Profile RJ45 MagJack, Tab Up, Orange&Green/ Yellow LED

The TeleWire Technology TWL81510A09NLV is a 10/100 Base-T EMI-finger shielded RJ45 MagJack with integrated magnetics. Manufactured in Taiwan.

Cross Reference

  • Bel Fuse L829-1J1T-47 — the TWL81510A09NLV cross-references to this part.
  • Bel Fuse L830-1J1T-47 — a further published equivalent on the same footprint.
  • LINK-PP LPJK70409A98NLV — 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 interface rate the magnetics are matched to.
  • Orange&Green/ Yellow LEDs — driven from the host; link and activity mapping is yours.
  • Integrated magnetics — isolation on all four pairs, short routing to the PHY.

Typical application: slim gateways and rack sleds where enclosure height is the binding constraint.

Pricing for the TWL81510A09NLV 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 L829-1J1T-47?
The TWL81510A09NLV from TeleWire Technology cross-references to the Bel Fuse L829-1J1T-47 and to LINK-PP LPJK70409A98NLV. 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.
Which manufacturers' parts does the TWL81510A09NLV replace?
The TWL81510A09NLV cross-references to Bel Fuse L829-1J1T-47; Bel Fuse L830-1J1T-47, and to LINK-PP LPJK70409A98NLV. TeleWire Technology publishes the full cross-reference so a sourcing engineer can qualify one Taiwan-built part against several incumbents at once.
How do I qualify the TWL81510A09NLV as a second source?
Request a sample of the TWL81510A09NLV and the mechanical drawing from TeleWire Technology, then check the footprint against the Bel Fuse L829-1J1T-47 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.
