TW27644A5NL 10/100/1000 Base-T RJ45 MagJack, Tab Up, Green&Yellow/ Green&Yellow LED

The TeleWire Technology TW27644A5NL is a 10/100/1000 Base-T EMI-finger shielded RJ45 MagJack with integrated magnetics. Manufactured in Taiwan.

Cross Reference

  • Bel Fuse 6605833 — the TW27644A5NL cross-references to this part.
  • TE Connectivity 6605833-6 — a further published equivalent on the same footprint.
  • LINK-PP LPJG16533A4NL — same footprint, sourced outside mainland China.

Selection Notes

  • 10/100/1000 Base-T — the transformer inside is specified for this rate.
  • Green&Yellow/ Green&Yellow LEDs — indicated condition set by the host PHY design.
  • 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: gigabit industrial switches and embedded controllers carrying the PHY on-board.

Pricing for the TW27644A5NL 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 6605833?
The TW27644A5NL from TeleWire Technology cross-references to the Bel Fuse 6605833 and to LINK-PP LPJG16533A4NL. 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 TW27644A5NL replace?
The TW27644A5NL cross-references to Bel Fuse 6605833; TE Connectivity 6605833-6, and to LINK-PP LPJG16533A4NL. 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 TW27644A5NL as a second source?
Request a sample of the TW27644A5NL and the mechanical drawing from TeleWire Technology, then check the footprint against the Bel Fuse 6605833 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.
