Key Parameters

Substitute Part Grouping Explanation

Substitute part eligibility for DC-DC converters is based strictly on matching electrical ratings (input range, output voltage, current, and power), isolation voltage, features, compliance statuses (RoHS, REACH), and mechanical characteristics (mounting type, package/case size). Substitutes are only included if all specified functional, safety, and mechanical parameters align with the main part requirements.

Parameter Comparison

Engineering Selection Recommendations

SPM15-150-Q12-C is obsolete. UEI15-150-Q12P-C offers strictly matched electrical and mechanical parameters, is ROHS3 Compliant, and holds the same ECCN and HTSUS classifications. REACH status differs; SPM15-150-Q12-C is REACH Unaffected, and UEI15-150-Q12P-C is REACH Affected. Selection should be based on the required compliance for the application. Both parts have specified through-hole mounting and the 6-DIP module form factor.

Frequently Asked Questions (FAQ)

Q: What key parameters determine substitute compatibility for the SPM15-150-Q12-C DC-DC converter?
A: Substitution requires matching type (isolated module), input voltage range (9V–36V), output voltage (15V), maximum output current (1.1A), output power (15W), isolation voltage (≥1.6kV), features, efficiency, operating temperature, mounting type, and compliance statuses.

Q: Are UEI15-150-Q12P-C and SPM15-150-Q12-C interchangeable in terms of size and mounting?
A: Both models use through-hole mounting and the 6-DIP module case. Their dimensions differ slightly: SPM15-150-Q12-C measures 1.00" x 1.00" x 0.41", while UEI15-150-Q12P-C measures 1.10" x 0.96" x 0.32". Both fit in standard 6-DIP module layouts.

Q: Does the difference in voltage isolation between the two models affect substitution?
A: UEI15-150-Q12P-C provides a higher isolation voltage (2.25kV) compared to SPM15-150-Q12-C (1.6kV). This parameter meets or exceeds the requirement.

Q: What should be considered regarding RoHS and REACH compliance when selecting a substitute?
A: Both modules are ROHS3 compliant. REACH status varies: SPM15-150-Q12-C is REACH Unaffected, UEI15-150-Q12P-C is REACH Affected. Selection must align with mandatory compliance and certification requirements for the intended application.
