Key Parameters

Substitute Part Grouping Explanation

Substitute parts are identified strictly by matching the following allowed electrical and mechanical parameters: number of outputs, input voltage range, output voltages, output currents, power rating, isolation voltage, mounting type, package/case format, size/dimension, certifications, RoHS compliance, and application category. Only parts that adhere to these criteria and maintain conformity with the physical and electrical specifications of PEM1-S5-D15-S are considered valid substitutes.

Parameter Comparison

Engineering Selection Recommendations

The PEM1-S5-D15-S is classified as "Obsolete." The manufacturer-recommended substitute, PEME1-S5-D15-S, is "Active" and conforms to RoHS standards. Both parts possess approval from CB Scheme, EN, IEC, and UL agencies. The provided substitute maintains electrical, mechanical, and certification compatibility per the allowed comparison fields. The substitute part has equivalent or improved performance by provided parameters and supports direct replacement in ITE (Commercial) designs.

Frequently Asked Questions (FAQ)

Q: What criteria are used to determine equivalence for DC-DC converter substitutes?
A: Equivalence is established strictly by matching the number of outputs, input voltage range, output voltages, output currents, total power, voltage isolation, mounting type, package/case, physical dimensions, certification, RoHS compliance, and application category.

Q: Is PEME1-S5-D15-S mechanically compatible with PEM1-S5-D15-S?
A: Both models share the same through-hole 7-SIP Module, 5 Leads, and similar mechanical envelope within specified dimensions.

Q: Are there differences in electrical performance relevant to substitution?
A: The substitute, PEME1-S5-D15-S, provides the same input/output voltage, number of outputs, isolation voltage, and total power rating, with slightly higher maximum output current (34mA).

Q: Does the substitute maintain required certifications and compliance?
A: Both parts are certified by CB Scheme, EN, IEC, and UL, and are RoHS compliant.

Q: Can the substitute be used in all original applications?
A: By comparison of provided parameters and application category (ITE Commercial), the substitute maintains compatibility.

Q: What should be considered regarding the product status when selecting a replacement?
A: The main part is marked "Obsolete"; selecting the "Active" substitute ensures ongoing supply and compliance with current standards.
