Substitute Part Grouping Explanation

Substitution grouping is strictly limited to DC DC converters with isolated module construction, matching output voltage, maximum output current, input voltage range, power rating, mounting type, and package style. Features such as protection circuits and regulatory compliance are included as provided. Only parts designated as active and compliant with identical RoHS status are considered for equivalence.

Parameter Comparison

Engineering Selection Recommendations

Both JCK1548S12 (XP Power) and SKE15C-12 (MEAN WELL USA Inc.) are active DC DC converter products, offered in tube packaging with ROHS3 compliance and MSL 1 ratings. Each part is classified EAR99 and HTSUS 8504.40.9580. Engineering selection between these models may be made on the basis of product status and conformance to compliance requirements as stated in the parameters.

Frequently Asked Questions (FAQ)

Q1: What are the mandatory parameters for substituting JCK1548S12?
A1: Mandatory parameters include the isolated module category, one output of 12V and 1.25A, input voltage range starting at 36V, 15W output power, through hole mounting, 5-DIP module package, compliant RoHS status, and part status as active.

Q2: Does the SKE15C-12 match the package requirements for substitution?
A2: Yes, SKE15C-12 is specified with a 5-DIP module package and through hole mounting, consistent with JCK1548S12.

Q3: What compliance characteristics must substitute parts share?
A3: Substitute components must meet ROHS3 compliance and MSL 1 (Unlimited). ECCN and HTSUS categorization must match as per provided data.

Q4: Are there differences in input voltage or output ratings impacting equivalence?
A4: Both have the same minimum input voltage (36V) and output rating (12V, 1.25A). The maximum input voltage for SKE15C-12 is 72V, compared to 75V for JCK1548S12.

Q5: Why is active part status required for substitution?
A5: Only active status assures ongoing availability and direct interchange suitability in new or continuing designs.
