SPM15-120-Q12P-C Equivalent & Substitute Parts Reference

Part Overview

The SPM15-120-Q12P-C from Murata Power Solutions Inc. is an obsolete DC-DC converter in the Isolated Module category, delivering a single 12V output at up to 1.3A from a 9V–36V input, with 15W maximum power. It features 1.6 kV isolation voltage and is designed for ITE (Commercial) applications. Given its obsolete status and the requirement for ongoing maintenance or replacement in existing designs, it is necessary to identify equivalent and substitute parts with matching or compatible electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

The substitute part grouping is established strictly according to matching electrical and mechanical parameters: isolated module type, input voltage range of 9V–36V, output voltage of 12V, maximum output current of 1.3A, 15W power, through hole mounting, 6-DIP module package, and operation within -40°C to 85°C. The substitution logic excludes any assumptions and relies solely on explicit parameter alignment between SPM15-120-Q12P-C and substitute parts.

Key substitution parameters:

• Type: Isolated Module
• Input Voltage Range: 9V – 36V
• Output Voltage: 12V
• Output Current (Max): 1.3A
• Power: 15 W
• Isolation Voltage
• Package / Case: 6-DIP Module
• Mounting Type: Through Hole
• Operating Temperature: -40°C ~ 85°C
• Mechanical Size

Engineering Selection Recommendations

The SPM15-120-Q12P-C DC-DC converter is obsolete. The UEI15-120-Q12P-C is currently active and is ROHS3 compliant. For applications requiring REACH unaffected status, only SPM15-120-Q12P-C fulfills that criterion in this comparison. Both parts share through hole mounting, 6-DIP module package, and similar electrical performance. Selection should match required inventory, compliance, and product status needs based on provided parameters.

Frequently Asked Questions (FAQ)

Q1: What are the main criteria for substituting SPM15-120-Q12P-C?
A1: Substitution requires matching input voltage range (9V–36V), single output of 12V at up to 1.3A, isolated module type, 15W power rating, through hole mounting, 6-DIP module package, and operating temperature of -40°C to 85°C.

Q2: Are there package or mounting differences between SPM15-120-Q12P-C and UEI15-120-Q12P-C?
A2: Both use a through hole mounting method and 6-DIP module package. Size/dimension differences exist; verification against actual PCB footprint may be required where mechanical fit is restricted.

Q3: How does compliance (RoHS, REACH) differ between SPM15-120-Q12P-C and its substitute?
A3: Both parts are ROHS3 compliant. SPM15-120-Q12P-C is REACH unaffected, while UEI15-120-Q12P-C is REACH affected based on the provided parameters.

Q4: What is the status of the substitute part compared to the original?
A4: SPM15-120-Q12P-C is obsolete. UEI15-120-Q12P-C is active and available for ongoing designs and replacement needs.

Q5: Does isolation voltage differ between original and substitute parts?
A5: Yes. SPM15-120-Q12P-C provides 1.6 kV isolation; UEI15-120-Q12P-C provides 2.25 kV. Both meet or exceed the minimum required isolation value specified for this category.

Q6: Does the efficiency vary significantly between SPM15-120-Q12P-C and UEI15-120-Q12P-C?
A6: Efficiency values are 84% for SPM15-120-Q12P-C and 84.5% for UEI15-120-Q12P-C. The difference is within allowed product category specification.
