Key Parameters

Substitute Part Grouping Explanation

Substitute selection for isolated module DC-DC converters in this product category is based on the following strictly defined parameters: input voltage range, output voltage, output current, power rating, isolation voltage, package type, mounting type, operating temperature, features, application class, efficiency, manufacturer compliance standards, and control features. All fields must match or meet the minimum specification of the main part for valid substitution.

Parameter Comparison

Engineering Selection Recommendations

The primary selection factor is the product lifecycle designation. ULS-3.3/30-D48P-C is obsolete, while ULS-3.3/30-D48N-C is active and in current production. The substitute part is ROHS3 Compliant and shares identical certifications, package, mechanical, and electrical specifications. Consider control polarity feature differences as identified. All environmental and compliance statuses are matched between parts.

Frequently Asked Questions (FAQ)

Q1: Which electrical parameters must match for direct substitution?
A1: Direct substitution requires identical values for input voltage range, output voltage, output current, power rating, and isolation voltage.

Q2: Are there any package or mounting differences between ULS-3.3/30-D48P-C and ULS-3.3/30-D48N-C?
A2: Both components utilize the same 8-DIP Module, 1/16 Brick package and through-hole mounting style, with matched physical dimensions.

Q3: What control feature should be considered when substituting?
A3: ULS-3.3/30-D48P-C has an "Enable, Active High" control feature; ULS-3.3/30-D48N-C uses "Enable, Active Low". Control circuits should be configured accordingly.

Q4: How do compliance statuses compare between the two parts?
A4: Main and substitute parts are RoHS compliant, have Moisture Sensitivity Level 1 (Unlimited), REACH unaffected, ECCN EAR99, and HTSUS 8504.40.9580.

Q5: Does the efficiency or application change in the substitute?
A5: The efficiency and application class (ITE Commercial) are identical for both parts. No change in performance or use case per provided data.
