TW5122CNL 10/100 Base-T RJ45 Jack, Tab Down, No LEDs

The TeleWire Technology TW5122CNL is a 10/100 Base-T EMI-finger shielded RJ45 jack. Manufactured in Taiwan.

Cross Reference

  • Bel Fuse SI-06233-F — the TW5122CNL cross-references to this part.
  • Bel Fuse SI-60233-F — a further published equivalent on the same footprint.
  • Halo HFJ-E2450HRL — a further published equivalent on the same footprint.

Selection Notes

  • 10/100 Base-T — the interface rate this housing is qualified for.
  • −40 °C to +85 °C — industrial range, not the commercial 0-to-70 grade.
  • No LEDs — the full front aperture stays clear for the mating plug.
  • EMI grounding fingers — chassis bond made at the bezel, not through the PCB.

Typical application: process and utility equipment installed in unconditioned plant rooms.

Pricing for the TW5122CNL ranges from $0.50 to $3.00 USD depending on order quantity and configuration, with volume tiers available on request.

Validate the TW5122CNL 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-06233-F?
The TW5122CNL from TeleWire Technology cross-references to the Bel Fuse SI-06233-F and to LINK-PP LPJ4011CNL. 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 TW5122CNL replace?
The TW5122CNL cross-references to Bel Fuse SI-06233-F; Bel Fuse SI-60233-F; Halo HFJ-E2450HRL; Halo HFJ11-E2450E-RL; Halo HFJ11-E2450HRL; Pulse JX0011D21NL, and to LINK-PP LPJ4011CNL. 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 TW5122CNL as a second source?
Request a sample of the TW5122CNL and the mechanical drawing from TeleWire Technology, then check the footprint against the Bel Fuse SI-06233-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.
