TW4J57312ADNL 10/100 Base-T 1x4 Port RJ45 Jack, Tab Down, Yellow/ Green LED

The TeleWire Technology TW4J57312ADNL is a 10/100 Base-T 1x4 EMI-finger shielded RJ45 jack. Manufactured in Taiwan.

Cross Reference

  • Bel Fuse SI-60065-F — the TW4J57312ADNL cross-references to this part.
  • LINK-PP LPJ46201ADNL — same footprint, sourced outside mainland China.

Selection Notes

  • 1x4 port array — 4 ports on one shell, saving panel width.
  • 10/100 Base-T — the rate the contact geometry is specified to.
  • Yellow/ Green LEDs — indicated condition set by the host PHY design.
  • EMI grounding fingers — spring contacts bond the shell to the panel on seating.

Typical application: patching and distribution boards that group ports behind a single opening.

Pricing for the TW4J57312ADNL 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 SI-60065-F?
The TW4J57312ADNL from TeleWire Technology cross-references to the Bel Fuse SI-60065-F and to LINK-PP LPJ46201ADNL. 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 TW4J57312ADNL be built to a different configuration?
Yes. The standard TW4J57312ADNL ships with Yellow/ Green LEDs and a tab-down 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 SI-60065-F.
How do I qualify the TW4J57312ADNL as a second source?
Request a sample of the TW4J57312ADNL and the mechanical drawing from TeleWire Technology, then check the footprint against the Bel Fuse SI-60065-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.
