Caddy for M610 and M620

Hi all,

I need caddies for M610 and M620 blades. I see some portals where this ref NRX7Y is ok for all two models but others where PN differs for M610 with ref 8FKXC / NTPP3 / G176J.

Could someone confirm what is the correct PN of caddy for each blade model?

Thanks in advance,
