Substitute Part Grouping Explanation

Substitution eligibility for the MALSECV00AG333EARK is determined by the following criteria:

Primary Compatibility Requirements:

Capacitance value: 330 µF (exact match required)
Tolerance: ±20% (exact match required)
Package type: Radial, Can - SMD (exact match required)
Case dimensions: 10.00 mm diameter, compatible height (maximum 10.60 mm acceptable for PCB layout)
Mounting type: Surface Mount (exact match required)
Voltage rating: Equal to or greater than 25 V (substitutes at higher voltage ratings are acceptable)
ESR: Equal to or lower than 640 mOhm @ 120 Hz (lower ESR is acceptable)
Lifetime: Equal to or greater than 2000 Hrs @ 105°C (extended lifetime is acceptable)
Operating temperature range: Must encompass or exceed -40°C ~ 105°C
RoHS compliance: ROHS3 Compliant (required for regulatory continuity)

Two substitute parts meet these criteria and are grouped as direct functional equivalents.

Engineering Selection Recommendations

337SVH035MGE (Cornell Dubilier SVH Series)

This substitute provides a voltage rating upgrade to 35 V while maintaining identical capacitance, tolerance, and case dimensions. The part is in active production status, ensuring long-term availability. ROHS3 compliance and MSL 1 rating match the original specification. The 700 mOhm ESR is marginally higher than the original but remains within acceptable operational parameters for general-purpose applications. This option is suitable for designs where higher voltage margin is beneficial.

ATB337M025 (Cornell Dubilier ATB Series)

This substitute matches the original voltage rating of 25 V and ESR specification of 640 mOhm, providing direct electrical equivalence. The extended lifetime rating of 5000 Hrs @ 105°C (versus 2000 Hrs) offers improved reliability margin. The expanded operating temperature range to -55°C provides additional environmental coverage. Active production status ensures procurement continuity. ROHS3 compliance and MSL 1 rating are maintained. This option is suitable for designs requiring direct parameter matching with enhanced reliability characteristics.

Both substitutes maintain ROHS3 compliance and unlimited moisture sensitivity level, ensuring regulatory and manufacturing process compatibility with the original component.

Frequently Asked Questions (FAQ)

Q: Can the 337SVH035MGE be used as a direct replacement for the MALSECV00AG333EARK?

A: Yes. The 337SVH035MGE is a direct functional substitute. It maintains identical capacitance (330 µF), tolerance (±20%), case dimensions (10.00 mm diameter), and package type (Radial, Can - SMD). The higher voltage rating (35 V versus 25 V) provides additional design margin and does not create compatibility issues in circuits designed for 25 V operation. ESR and lifetime specifications remain within acceptable ranges for general-purpose applications.

Q: Can the ATB337M025 be used as a direct replacement for the MALSECV00AG333EARK?

A: Yes. The ATB337M025 is a direct functional substitute with identical voltage rating (25 V), capacitance (330 µF), tolerance (±20%), ESR (640 mOhm @ 120 Hz), and case dimensions (10.00 mm diameter). The extended lifetime (5000 Hrs @ 105°C) and expanded temperature range (-55°C ~ 105°C) provide enhanced reliability without affecting electrical compatibility.

Q: Are there any PCB layout considerations when substituting these parts?

A: The 337SVH035MGE has a maximum seated height of 10.60 mm compared to the original 10.50 mm. Verify that PCB clearance accommodates this 0.10 mm height difference. Both substitutes maintain the same 10.30 mm x 10.30 mm surface mount land size, ensuring pad compatibility without layout modification.

Q: Which substitute should be selected for new designs?

A: Selection depends on design requirements. Choose the 337SVH035MGE for applications benefiting from higher voltage margin. Choose the ATB337M025 for applications requiring extended operational lifetime and broader temperature range. Both are active production parts with established supply chains.

Q: Do the substitute parts maintain RoHS and MSL compliance?

A: Yes. Both 337SVH035MGE and ATB337M025 are ROHS3 compliant with MSL 1 (Unlimited) rating, matching the original component's regulatory and manufacturing process requirements.
