Key Parameters

Substitute Part Grouping Explanation

Substitution is based strictly on the following key parameters: manufacturer, output voltage, output current, power rating, input voltage range, application, operating temperature range, mounting type, packaging/case, compliance status, and regulatory approvals. Only parts that match these criteria as explicitly provided are grouped as suitable substitutes.

Parameter Comparison

Engineering Selection Recommendations

Selection should be based on product lifecycle status, regulatory compliance (RoHS3, REACH, ECCN), and required safety approvals (CB, CE, cURus, TUV, EAC). The PM-20-15 is obsolete, while the MPM-20-15 is an active product with the same manufacturer, comparable voltage, current, power ratings, and universal input features. Both parts are RoHS3 compliant and REACH unaffected, and have approvals suitable for medical applications.

Frequently Asked Questions (FAQ)

Q1: Which key parameters must match when selecting a substitute for the PM-20-15?
A1: Output voltage, output current, power rating, input voltage range, application, compliance certifications, mounting type, and package/case are the critical parameters.

Q2: Are there any dimensional differences between PM-20-15 and MPM-20-15?
A2: Yes, the PM-20-15 uses a 6-DIP module (94.0mm x 56.0mm x 22.7mm), whereas the MPM-20-15 uses a 4-DIP module (52.4mm x 27.2mm x 24.0mm). Dimensional compatibility should be verified within the system design.

Q3: Do both models hold the necessary safety and environmental certifications?
A3: Both models are RoHS3 compliant, REACH unaffected, and carry CB, CE, cURus, and TUV approvals. The MPM-20-15 also has EAC certification.

Q4: How does product status affect part selection?
A4: PM-20-15 is obsolete, whereas MPM-20-15 is active, ensuring ongoing availability for new and existing designs.

Q5: What is the difference in efficiency and regulation between the two models?
A5: MPM-20-15 has higher efficiency (87% vs. 83%) and tighter line and load regulation compared to PM-20-15.

Q6: Are the mounting styles identical?
A6: Both models utilize through-hole mounting, ensuring consistency in this aspect.
