Key Parameters

Substitute Part Grouping Explanation

Substitute parts for MER1S1509SC must match the following critical electrical and mechanical parameters: input voltage range (13.5V–16.5V), output voltage (9V), output current (111mA), power rating (1W), isolation rating, efficiency, mounting type, package/case, size/dimension, operating temperature, compliance (RoHS, REACH), and number of outputs. Only parts fully matching these parameters are categorized as valid substitutes.

Parameter Comparison

Engineering Selection Recommendations

MER1S1509SC is obsolete. MEV1S1509SC is active, RoHS compliant, and REACH unaffected. Both parts have matching electrical and mechanical parameters required for substitution. MEV1S1509SC offers an increased isolation rating compared to MER1S1509SC. Both parts are suitable for ITE (commercial) applications. Selection can be made strictly on the basis of product status and required compliance certifications.

Frequently Asked Questions (FAQ)

What key parameters must match when selecting a substitute for MER1S1509SC?
All critical electrical characteristics—input voltage range, output voltage, output current, power rating, isolation, efficiency—along with mechanical features—mounting type, package, and size—must match exactly.

Is MEV1S1509SC a direct replacement for MER1S1509SC?
MEV1S1509SC matches all electrical and mechanical parameters with MER1S1509SC and is suitable for substitution in identical operating environments.

Does the package type and pinout of MEV1S1509SC match MER1S1509SC?
Both use the 7-SIP Module, 4 Leads package. Dimensions and mounting are identical.

Are there differences in compliance and certifications?
Both parts are RoHS compliant and REACH unaffected. There are no differences in compliance status.

Is there any change required in application due to the difference in isolation voltage?
MEV1S1509SC provides a higher isolation rating (3kV vs. 1kV). All other functional parameters match; no change is required in standard applications within the allowed characteristics.
