TW4J57912BENL 10/100/1000 Base-T 1x4 Port RJ45 Jack, Tab Down, Green/ Yellow LED

The TeleWire Technology TW4J57912BENL is a 10/100/1000 Base-T 1x4 shielded RJ45 jack. Manufactured in Taiwan.

Cross Reference

  • Hanrun HY911431A — the TW4J57912BENL cross-references to this part.
  • LINK-PP LPJG46801BENL — same footprint, sourced outside mainland China.

Selection Notes

  • 1x4 port array — 4 ports on one shell, saving panel width.
  • 10/100/1000 Base-T — the interface rate this housing is qualified for.
  • Green/ Yellow LEDs — driven from the host; link and activity mapping is yours.
  • Shielded shell without EMI fingers — the shield terminates through the PCB.

Typical application: switch and router line cards, where port density per panel inch drives the design.

Pricing for the TW4J57912BENL 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 Hanrun HY911431A?
The TW4J57912BENL from TeleWire Technology cross-references to the Hanrun HY911431A and to LINK-PP LPJG46801BENL. 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 TW4J57912BENL be built to a different configuration?
Yes. The standard TW4J57912BENL ships with Green/ Yellow 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 Hanrun HY911431A.
How do I qualify the TW4J57912BENL as a second source?
Request a sample of the TW4J57912BENL and the mechanical drawing from TeleWire Technology, then check the footprint against the Hanrun HY911431A 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.
