TWD1123DNL 10/100 Base-T Vertical RJ45 MagJack, Tab Up, No LEDs

The TeleWire Technology TWD1123DNL is a 10/100 Base-T shielded RJ45 MagJack with integrated magnetics. Manufactured in Taiwan.

Cross Reference

  • Bel Fuse SI-16001-F — the TWD1123DNL cross-references to this part.
  • Hanrun HY951140A — a further published equivalent on the same footprint.
  • X Multiple XRJV-01V-0-D12-080 — a further published equivalent on the same footprint.

Selection Notes

  • Vertical (180°) body — the plug seats vertically, keeping the board edge clear.
  • 10/100 Base-T — the transformer inside is specified for this rate.
  • No LEDs — no light pipes to align against the panel cut-out.
  • Shielded shell without EMI fingers — grounding becomes a layout decision, not a mechanical one.

Typical application: DIN-rail modules whose width is fixed and whose depth is not.

Pricing for the TWD1123DNL ranges from $0.50 to $3.00 USD depending on order quantity and configuration, with volume tiers available on request.

Validate the TWD1123DNL 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 SI-16001-F?
The TWD1123DNL from TeleWire Technology cross-references to the Bel Fuse SI-16001-F and to LINK-PP LPJD0012DNL. 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 TWD1123DNL replace?
The TWD1123DNL cross-references to Bel Fuse SI-16001-F; Hanrun HY951140A; X Multiple XRJV-01V-0-D12-080; YDS 51F-1203ND2, and to LINK-PP LPJD0012DNL. 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 TWD1123DNL as a second source?
Request a sample of the TWD1123DNL and the mechanical drawing from TeleWire Technology, then check the footprint against the Bel Fuse SI-16001-F 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.
