TW1944CG5NL 10/100/1000 Base-T RJ45 MagJack, Tab Down, Green&Yellow/ Green&Yellow LED
The TeleWire Technology TW1944CG5NL is a 10/100/1000 Base-T EMI-finger shielded RJ45 MagJack with integrated magnetics. Manufactured in Taiwan.
Cross Reference
- Moxie MOX-RJ45-1840 — the TW1944CG5NL cross-references to this part.
- TE Connectivity 1840475 — a further published equivalent on the same footprint.
- LINK-PP LPJG0833CG4NL — same footprint, sourced outside mainland China.
Selection Notes
- 10/100/1000 Base-T — the rate the internal transformer is wound for.
- Green&Yellow/ Green&Yellow LEDs — wired to the host PHY, not to internal logic.
- Integrated magnetics — the transformer sits in the shell, freeing board area beside the PHY.
- EMI grounding fingers — shield path closes against the chassis bezel.
Typical application: gigabit industrial switches and embedded controllers carrying the PHY on-board.
Pricing for the TW1944CG5NL ranges from $0.50 to $3.00 USD depending on order quantity and configuration, with volume tiers available on request.
