The Siemens 6ES7195-3CF20-0AD0 is the SIMATIC CP 1625-2, a PCIe communications processor for PROFINET RT and IRT. It carries two independent PROFINET interfaces, each with two switched RJ45 ports — so you can wire a line or ring topology without an external switch. What matters for procurement: this is a class D (made-to-order) product, meaning every unit is built to the customer's specification and requires engineering services from Siemens. It is not a stocked shelf item; expect a quoted lead time against an RFQ.
Sourcing Reality
This is a made-to-order communications processor. No distributor holds it available via RFQ confirmation; each piece is configured and built per the customer's engineering specification. Secure your project schedule by submitting an RFQ early — the product class D designation triggers a custom manufacturing flow that cannot be shortcut with an off-the-shelf substitute. No direct pin-compatible alternative exists within the same family; the CP 1625-2 is the only PCIe card with dual PROFINET RT/IRT interfaces in the current Siemens catalog.
