Key Parameters

Substitute Part Grouping Explanation

Substitution logic for DC-DC Converters in the Non-Isolated PoL Module category is strictly determined by these key parameters: Series, Type, Number of Outputs, Voltage - Input (Min/Max), Voltage - Output, Current - Output (Max), Operating Temperature, Efficiency, Mounting Type, Package / Case, Size / Dimension, RoHS Status, Moisture Sensitivity Level (MSL), REACH Status, and Product Status. Only parts matching these criteria are considered equivalent substitutes for PSA55-7IR.

Parameter Comparison

Engineering Selection Recommendations

Both PSA55-7IR and the substitute PSA55-7R are listed as Active products and meet ROHS3 compliance and REACH unaffected status. Moisture Sensitivity Level (MSL) for both is rated at 1 (Unlimited), indicating no moisture sensitivity constraints. The shared compliance, certifications, and product status support direct interchangeability within applications that require non-isolated PoL modules with the specified electrical and mechanical parameters.
