Is there a pin-compatible replacement for G2406S?

Several 24-pin 1000Base-T transformers exist, but pin compatibility is not guaranteed without comparing datasheets. Parts like KG2401PR A1 and HX5084FNL are strong candidates for form-fit-function replacement and require pinout verification.

What risks should I check before replacing G2406S?

The primary risks are electrical and mechanical. Verify the pinout is identical to avoid board redesign. Also, check secondary parameters like DC Resistance (DCR) and insertion/return loss across the full frequency range to ensure signal integrity is maintained.

G2406S Alternatives, Datasheet & Cross Reference | CND-tek

The G2406S is a single-port 1000Base-T Ethernet transformer module. Key alternatives include other 24-pin SMD transformers with 350uH inductance and 1500Vrms isolation, but require pinout verification.
