Key Parameters

Substitute Part Grouping Explanation

Substitution of DC-DC converter modules requires direct equivalence in critical parameters. All substitute parts included must match in: input voltage range, output voltage, output current, output power, number of outputs, isolation voltage class, mounting type, mechanical package and dimensions (within form factor equivalence), and application suitability. Product status and RoHS compliance also determine ongoing availability and environmental compatibility for engineering continuity.

Parameter Comparison

Engineering Selection Recommendations

Based solely on product status and compliance criteria, SPM15-033-Q12P-C is marked as "Last Time Buy," while UEI15-033-Q12P-C is listed as "Active." Both models are ROHS3 compliant. Selecting UEI15-033-Q12P-C ensures alignment with regulatory requirements and continuing manufacturer support.

Frequently Asked Questions (FAQ)

Q: What key electrical parameters must match to substitute DC-DC converter modules in this group?
A: Input voltage range, output voltage, output current, output power, isolation voltage, and number of outputs are required to be identical for functional substitution.

Q: Are package or mounting type critical for substitution?
A: Yes, both parts use the 6-DIP module case and through-hole mounting. This ensures mechanical and soldering compatibility within the same circuit footprint.

Q: How does product status affect substitute selection?
A: "Active" status indicates ongoing availability and long-term manufacturer support, while "Last Time Buy" signals end-of-life, necessitating alternatives for continued sourcing.

Q: Are environmental compliances considered in these substitutions?
A: Both selected parts are ROHS3 compliant, confirming their suitability for RoHS-regulated applications.

Q: Is there any difference in operational characteristics between these parts?
A: The substitute UEI15-033-Q12P-C has a higher isolation voltage and slight dimensional variation but matches all critical electrical and mechanical parameters required for substitution.
