TW2J37937CNL 10/100/1000 Base-T 1x2 Port RJ45 Jack, Tab Down, No LEDs

The TeleWire Technology TW2J37937CNL is a 10/100/1000 Base-T 1x2 EMI-finger shielded RJ45 jack. Manufactured in Taiwan.

Cross Reference

  • Halo HFJ12-1G11ERL — the TW2J37937CNL cross-references to this part.
  • Halo HFJ12-1G11RL — a further published equivalent on the same footprint.
  • LINK-PP LPJGF26826CNL — same footprint, sourced outside mainland China.

Selection Notes

  • 1x2 port array — 2 ports on one shell, saving panel width.
  • 10/100/1000 Base-T — the interface rate this housing is qualified for.
  • No LEDs — the full front aperture stays clear for the mating plug.
  • EMI grounding fingers — spring contacts bond the shell to the panel on seating.

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

Pricing for the TW2J37937CNL 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 Halo HFJ12-1G11ERL?
The TW2J37937CNL from TeleWire Technology cross-references to the Halo HFJ12-1G11ERL and to LINK-PP LPJGF26826CNL. 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 TW2J37937CNL replace?
The TW2J37937CNL cross-references to Halo HFJ12-1G11ERL; Halo HFJ12-1G11RL, and to LINK-PP LPJGF26826CNL. 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 TW2J37937CNL as a second source?
Request a sample of the TW2J37937CNL and the mechanical drawing from TeleWire Technology, then check the footprint against the Halo HFJ12-1G11ERL 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.
