Key Parameters

Substitute Part Grouping Explanation

Substitutes for PDM2-S24-D15-D are selected strictly based on matching critical electrical parameters, including output voltages (+15V, -15V), maximum output current (67mA, 67mA), number of outputs (2), input voltage range (21.6V – 26.4V), output power (2W), isolation voltage (1.5kV), mounting type (through hole), package form factor, operating temperature range, and compliance (RoHS, REACH, safety standards). Substitute relationships are limited to parts with these exact specifications.

Parameter Comparison

Engineering Selection Recommendations

For applications currently using PDM2-S24-D15-D, alternative selection is determined by matching electrical parameters, compliance, and operating temperature. PDME2-S24-D15-D and PDME2-S24-D15-S are active alternatives with the same voltage, current, isolation, and input requirements. Regulatory and RoHS/REACH compliance differ slightly between models; review the specified certifications and compliance entries to ensure adherence to application requirements.

Frequently Asked Questions (FAQ)

Q1: What are the critical substitution criteria when replacing PDM2-S24-D15-D?
The primary criteria are matching output voltages, maximum output current, input voltage range, power, isolation rating, mounting method, operating temperature range, number of outputs, and compliance with relevant standards and RoHS/REACH requirements.

Q2: Are there mechanical package differences among the substitutes?
Yes. PDM2-S24-D15-D uses a 14-DIP module, while PDME2-S24-D15-D uses a 7-SIP and PDME2-S24-D15-S uses a 6-SIP package. Pin compatibility and board layout must be reviewed for direct replacement.

Q3: How do approval and compliance marks differ?
Approval agencies and standard numbers differ across these models. PDM2-S24-D15-D has CB Scheme, EN, IEC, and UL approvals. Alternatives list cURus, CE, and compliance with 62368-1, with differing RoHS and REACH entries. Match to your application’s compliance and regulatory requirements.

Q4: Is there any difference in output power or efficiency between the listed parts?
Efficiency values differ by 1% (84% vs. 83%). Output power for alternatives is equal or marginally higher (2 W vs. 2.01 W for PDME2-S24-D15-S).

Q5: What must be considered for mounting type compatibility?
All units are through-hole devices; however, package size, form factor, and lead configuration differ and must align with the PCB design for successful substitution.
