Key Parameters

Substitute Part Grouping Explanation

Substitution is established strictly by matching the following key electrical and mechanical parameters for this product category: input voltage range, output voltage, output current, output power (Watts), isolation voltage, number of outputs, type (Isolated Module), mounting type (Through Hole), package/case (4-SIP Module), operating temperature range, efficiency, and RoHS status. All substitute parts are grouped only when these parameters conform precisely or within stated limits, ensuring full functional equivalence and form-fit compatibility.

Parameter Comparison

Engineering Selection Recommendations

Selection of substitute parts for Murata Power Solutions Inc. MEE1S0309SC should be based on the matching of product status (Obsolete), RoHS certification compliance, and provided inventory for new original units. Substitute part NKE0309SC meets RoHS3 compliance and is classified as obsolete, aligning with the main part requirements. No additional technical criteria beyond those provided are introduced for engineering selection.

Frequently Asked Questions (FAQ)

Q1: What are the primary criteria for substituting isolated DC DC converter modules in this category?
A1: Substitution is strictly determined by matching input voltage range, output voltage, output current, output power, isolation voltage, number of outputs, operating temperature range, mounting type, package/case, and RoHS compliance.

Q2: Can NKE0309SC be used in place of MEE1S0309SC in the same PCB footprint?
A2: NKE0309SC shares the same 4-SIP Module package type and through hole mounting, supporting direct mechanical replacement in compatible layouts.

Q3: Are there key differences in electrical performance between MEE1S0309SC and NKE0309SC?
A3: The substitute part NKE0309SC offers higher isolation voltage (3 kV versus 1 kV) and lower efficiency (74% versus 81.5%), based solely on supplied parameters.

Q4: Is regulatory compliance maintained when using NKE0309SC as a substitute?
A4: Both MEE1S0309SC (RoHS Compliant) and NKE0309SC (ROHS3 Compliant) maintain stated RoHS conformities per manufacturer specification.

Q5: What packaging and size differences should be considered?
A5: Both models utilize the 4-SIP Module case with identical length and width. NKE0309SC is shorter in height (0.29" vs 0.39"), requiring confirmation of mechanical height compatibility within application constraints using only the provided dimensions.
