Key Parameters

Substitute Part Grouping Explanation

Substitution for the ULT-3.3/7.5-D48P-C is based on matching the following key parameters: input voltage range, output voltage, output current, maximum output power, isolation voltage, application category, thermal operating range, efficiency, mounting and package form factor, controlling features, and compliance status. Only substitute models with identical or equivalent values in these parameters are listed.

Parameter Comparison

Engineering Selection Recommendations

Selection should be based on matching product status and regulatory compliance parameters. Both ULT-3.3/7.5-D48P-C and ULT-3.3/7.5-D48N-C meet RoHS and REACH environmental directives and have unrestricted moisture sensitivity levels. The key differentiator is product status: ULT-3.3/7.5-D48P-C is "Not For New Designs" and ULT-3.3/7.5-D48N-C is "Obsolete." Control features differ only in the logic level (active high vs. active low). Both are permitted for substitution within identical regulatory and mechanical constraints per the provided information.

Frequently Asked Questions (FAQ)

Q1: What are the critical substitution criteria for ULT-3.3/7.5-D48P-C?
A1: Substitution requires strict equivalence in input voltage range, output voltage/current, isolation voltage, mounting form factor, thermal and electrical ratings, compliance status, and control features.

Q2: Are the ULT-3.3/7.5-D48P-C and ULT-3.3/7.5-D48N-C pin compatible?
A2: Both have identical package/casing types and dimensions: 8-DIP Module, 1/32 Brick, 0.92" x 0.75" x 0.35" (23.4mm x 19.1mm x 8.9mm).

Q3: How do the control features affect substitution?
A3: ULT-3.3/7.5-D48P-C uses Enable, Active High; ULT-3.3/7.5-D48N-C uses Enable, Active Low. Selection must consider the required control logic in the application.

Q4: What compliance standards do these DC-DC converters meet?
A4: Both models are RoHS compliant and REACH unaffected with MSL 1 (Unlimited).

Q5: Is the substitute part suitable for the same applications and operating conditions?
A5: All substitute models match application category, voltage/current output, isolation, efficiency, and temperature ratings per provided data.

Q6: Why is substitution necessary given current product status?
A6: The main part, ULT-3.3/7.5-D48P-C, is "Not For New Designs" and the substitute, ULT-3.3/7.5-D48N-C, is "Obsolete," impacting long-term sourcing and design-in decisions.
