SPM15-033-Q12N-C Equivalent & Substitute Parts Reference

Part Overview

Murata Power Solutions Inc. SPM15-033-Q12N-C is an isolated DC-DC converter classified under the SPM15 (15W) series. It provides a regulated single output of 3.3V at up to 4.5A, accepting a wide input voltage range from 9V to 36V. Packaged in a 6-DIP through-hole module, it incorporates industry-standard features such as remote on/off, overcurrent protection (OCP), overtemperature protection (OTP), overvoltage protection (OVP), short circuit protection (SCP), and undervoltage lockout (UVLO). As the part status is listed as “Obsolete,” identifying alternative models with strictly matching electrical, mechanical, and compliance parameters is necessary for continued design support and inventory replacement.

Key Parameters

Substitute Part Grouping Explanation

Substitution is strictly permitted when the following parameters are matched: input voltage range, output voltage and current, isolation voltage, power rating, output count, mounting method, package type, module dimensions, compliance status (RoHS, REACH), and suitable applications. Only parts with a through-hole 6-DIP module form factor and equivalent electrical performance for ITE (Commercial) usage are included. Features relevant to control and protection, as explicitly listed, are also matched where data is provided.

Parameter Comparison

Engineering Selection Recommendations

Selections are based on availability and compliance. SPM15-033-Q12N-C is obsolete; the listed substitute, PKE3210PI from Flex Power Modules, carries an active product status. Both modules are ROHS3 compliant and REACH unaffected. Suitability for ITE (Commercial) applications is retained. Approvals and certifications relevant to standard agency requirements are included for the substitute part, where specified.

Frequently Asked Questions (FAQ)

Q: What primary parameters must be matched for DC-DC converter substitution?
A: Input voltage range, output voltage, output current, isolation voltage, power rating, number of outputs, mounting method, package type, dimensions, application classification, control features, and compliance statuses (RoHS, REACH).

Q: Are mechanical mounting and dimensions compatible between SPM15-033-Q12N-C and PKE3210PI?
A: Both utilize a 6-DIP module through-hole package, with matching length and width and minor height variation.

Q: Are there noteworthy compliance differences between the main and substitute parts?
A: Both parts are ROHS3 compliant and REACH unaffected.

Q: Do both parts provide equivalent control features for system integration?
A: Enable and active low control features are present on both models.

Q: Is substitution possible for ITE (Commercial) applications?
A: Both parts are specified for ITE (Commercial) use.

Q: Why is an obsolete status significant for engineering selection?
A: Obsolescence necessitates selection of an active, compliant alternative to ensure procurement and product lifecycle continuity.

Q: What inventory considerations should be accounted for with these part numbers?
A: SPM15-033-Q12N-C is obsolete but available in current stock; PKE3210PI is active with inventory details provided.
