Frequently asked questions
When sourcing RJ71PB91V, what is the closest functional second-source?
QJ71C24 is the closest same-class peer — a Mitsubishi PLC expansion module at the same 0.20 kg weight — but it is a sibling in the same family, not a verified second-source with the same iQ-R comms profile. Treat it as a cross-shop candidate, confirm the function before specifying.
