Key difference
YubiKey 5C NFC FIPS is the stronger choice when certification, mature ecosystem, documented protocol support, and government/regulated deployment are the priorities. Yubico officially documents FIPS 140-3, FIDO2 Level 2, PIV, OpenPGP, HOTP/TOTP, NFC and USB-C on this model.
FEITIAN K40 Plus FIPS is potentially more attractive where OEM customization, optional applets, and pricing are important. Its proposed configuration—FIDO2 + U2F + NFC + USB-C + optional HOTP/TOTP + PIV + OpenPGP—can provide a similar multi-protocol feature set, but the exact applet and FIPS configuration should be confirmed with FEITIAN before claiming feature equivalence.
