TW2123AGNL 10/100 Base-T RJ45 MagJack, Tab Up, Yellow/ Green LED

The TeleWire Technology TW2123AGNL is a 10/100 Base-T EMI-finger shielded RJ45 MagJack with integrated magnetics. Manufactured in Taiwan.

Cross Reference

  • Hanrun HY911169C — the TW2123AGNL cross-references to this part.
  • Pulse J1012F21C — a further published equivalent on the same footprint.
  • Pulse J1012F21CNL — a further published equivalent on the same footprint.

Selection Notes

  • 10/100 Base-T — the transformer inside is specified for this rate.
  • Yellow/ Green LEDs — driven from the host; link and activity mapping is yours.
  • Integrated magnetics — one placement replaces the discrete magnetics and its routing.
  • EMI grounding fingers — chassis bond made at the bezel, not through the PCB.

Typical application: building-control panels and sensor gateways on 10/100 links.

Pricing for the TW2123AGNL ranges from $0.50 to $3.00 USD depending on order quantity and configuration, with volume tiers available on request.

Validate the TW2123AGNL 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 Hanrun HY911169C?
The TW2123AGNL from TeleWire Technology cross-references to the Hanrun HY911169C and to LINK-PP LPJ1012AGNL. 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 TW2123AGNL replace?
The TW2123AGNL cross-references to Hanrun HY911169C; Pulse J1012F21C; Pulse J1012F21CNL; YDS 47F-1206-YGD2NL, and to LINK-PP LPJ1012AGNL. 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 TW2123AGNL as a second source?
Request a sample of the TW2123AGNL and the mechanical drawing from TeleWire Technology, then check the footprint against the Hanrun HY911169C 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.
