Key Parameters

Substitute Part Grouping Explanation

Substitution is determined strictly by matching the following key parameters: input voltage range, output voltage and current, isolation voltage, power rating, mounting type, package, operating temperature, relevant compliance (RoHS, REACH), and approval agency standards. Only substituting parts that conform to these values and regulatory standards are listed.

Parameter Comparison

Engineering Selection Recommendations

The main part number PEM2-S5-S5-D is obsolete and requires replacement with an active, compliant part for ongoing applications. Substitute parts PEME2-5-S5-D and PEME2-S5-S5-S match the necessary RoHS and REACH compliance standards and carry relevant product approvals. All substitute parts listed are active and possess appropriate certifications for use in ITE (Commercial) applications according to the provided standards.

Frequently Asked Questions (FAQ)

Q1: What key parameters must match for a substitute to be selected for PEM2-S5-S5-D?
A1: Required matching parameters are input voltage range, output voltage and current, isolation voltage, power rating, mounting type, package, operating temperature, compliance standards, and approval agency certifications.

Q2: Are there differences in package type among the listed substitutes?
A2: PEM2-S5-S5-D and PEME2-5-S5-D use 14-DIP modules, while PEME2-S5-S5-S utilizes a 7-SIP module. Package type may affect mechanical compatibility with the original PCB layout.

Q3: Is efficiency a determining factor for substitution?
A3: Efficiency for the substitute parts is 84% compared to the main part's 85%. This is within typical tolerances for equivalent DC-DC converters in this category.

Q4: Do all substitutes carry current compliance and approval certifications?
A4: All listed substitutes meet RoHS and REACH standards and hold appropriate approval agency certifications as provided in their specifications.

Q5: What are the implications of “Product Status: Obsolete” for PEM2-S5-S5-D?
A5: Obsolete status indicates PEM2-S5-S5-D is no longer in production. Only active parts should be considered for new designs or replacements to ensure ongoing supply and support.
