Substitute Part Grouping Explanation

Substitute parts for the MOCD211R2M are identified based on the following criteria:

Primary Matching Parameters:

Number of Channels: 2
Output Type: Transistor
Mounting Type: Surface Mount
Package / Case: 8-SOIC form factor
Input Type: DC
RoHS Status: ROHS3 Compliant
Product Status: Active

Isolation Voltage Consideration: The MOCD211R2M operates at 2500Vrms isolation. Substitute parts with equal or higher isolation voltage (2500Vrms, 3000Vrms, or 4000Vrms) are functionally compatible, as higher isolation ratings provide equivalent or superior performance in applications requiring the specified isolation level.

Current Transfer Ratio and Output Current: Substitute parts must support the required current transfer ratio and output current specifications. Parts with higher current transfer ratios or output current capabilities remain compatible for applications designed around the MOCD211R2M baseline specifications.

Switching Speed: Turn-on and turn-off times, along with rise and fall times, determine switching performance. Substitute parts with equal or faster switching characteristics maintain functional compatibility.
