TW2J37515AENL 10/100/1000 Base-T 1x2 Port RJ45 Jack, Tab Down, Green/ Yellow LED

The TeleWire Technology TW2J37515AENL is a 10/100/1000 Base-T 1x2 EMI-finger shielded RJ45 jack. Manufactured in Taiwan.

Cross Reference

  • Halo HFJ12-E2450ER-L12RL — the TW2J37515AENL cross-references to this part.
  • Pulse JX80-0037NL — a further published equivalent on the same footprint.
  • Pulse JXD0-2005NL — a further published equivalent on the same footprint.

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.
  • Green/ Yellow LEDs — wired to the host PHY, not to internal logic.
  • −40 °C to +85 °C — industrial range, not the commercial 0-to-70 grade.

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

Pricing for the TW2J37515AENL 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-E2450ER-L12RL?
The TW2J37515AENL from TeleWire Technology cross-references to the Halo HFJ12-E2450ER-L12RL and to LINK-PP LPJ26404AENL. 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 TW2J37515AENL replace?
The TW2J37515AENL cross-references to Halo HFJ12-E2450ER-L12RL; Pulse JX80-0037NL; Pulse JXD0-2005NL; Pulse JXR8-1001NL; YDS 62F-1204GYD2NL, and to LINK-PP LPJ26404AENL. 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 TW2J37515AENL as a second source?
Request a sample of the TW2J37515AENL and the mechanical drawing from TeleWire Technology, then check the footprint against the Halo HFJ12-E2450ER-L12RL 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.
