TWL81510B09NLV 10/100 Base-T Low-Profile RJ45 MagJack, Tab Up, Orange&Green/ Yellow LED

The TeleWire Technology TWL81510B09NLV is a 10/100 Base-T shielded RJ45 MagJack with integrated magnetics. Manufactured in Taiwan.

Cross Reference

  • Bel Fuse L830-1JX1-47 — the TWL81510B09NLV cross-references to this part.
  • Bel Fuse L836-1JX1-47 — a further published equivalent on the same footprint.
  • LINK-PP LPJK70409B98NLV — 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.
  • Orange&Green/ Yellow LEDs — wired to the host PHY, not to internal logic.
  • Shielded shell without EMI fingers — the shield terminates through the PCB.

Typical application: 1U and half-height equipment with very little board-to-lid clearance.

Pricing for the TWL81510B09NLV 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 L830-1JX1-47?
The TWL81510B09NLV from TeleWire Technology cross-references to the Bel Fuse L830-1JX1-47 and to LINK-PP LPJK70409B98NLV. 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 TWL81510B09NLV replace?
The TWL81510B09NLV cross-references to Bel Fuse L830-1JX1-47; Bel Fuse L836-1JX1-47, and to LINK-PP LPJK70409B98NLV. 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 TWL81510B09NLV as a second source?
Request a sample of the TWL81510B09NLV and the mechanical drawing from TeleWire Technology, then check the footprint against the Bel Fuse L830-1JX1-47 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.
