Substitute Part Grouping Explanation

Substitute parts are identified strictly by matching electrical and mechanical parameters. Electrical compatibility is established by equivalent voltage and current ratings, power output, input range, number of outputs, and regulation characteristics. Mechanical and mounting parameters, including package type, size, and through-hole configuration, are matched for direct replacement. Compliance (RoHS, REACH), approval agency certifications, and moisture sensitivity are included to support regulated applications and supply chain continuity.

Engineering Selection Recommendations

PM-10-12 is obsolete. Substitute selection should use only models with equivalent or better compliance ratings, such as those with ROHS3 or RoHS, approval agency certification (CB, CE, cURus, TUV, CSA, cUL, EN, IEC, UL), and consistent moisture sensitivity levels. Select substitutes that maintain matching output voltage, current, power requirements, and input voltage ranges to ensure direct compatibility, as reflected in the parameter comparison table.

Frequently Asked Questions (FAQ)

Q1: What parameters must be matched for a substitute AC/DC converter in the PM-10-12 footprint?
A1: Output voltage, maximum output current, power rating, input voltage range, number of outputs, package/case, mounting type, and regulatory/compliance certifications.

Q2: Can substitute parts be used without re-designing the PCB?
A2: Substitutes featuring the same package/case (4-DIP Module) and identical through-hole mounting are suitable for direct replacement as per provided specifications.

Q3: Are all substitute parts compliant with RoHS and moisture sensitivity requirements?
A3: All listed substitutes are RoHS or ROHS3 compliant and have a Moisture Sensitivity Level of 1 (Unlimited).

Q4: Is there any variance in agency approvals or application suitability?
A4: Substitute parts maintain a range of agency approvals. Medical and ITE (Commercial) applications are both covered, depending on the selected model and agency certifications listed.

Q5: How should efficiency and operating temperature differences be considered?
A5: Select a substitute part only from the parameter table provided. Differences in efficiency and operating temperature must be within the specified ranges for compatibility.

Q6: Are input voltage ranges comparable between the main and substitute parts?
A6: Input voltage ranges of all substitutes align with or exceed the requirements set by PM-10-12 within the ranges stated.
