Substitute Part Grouping Explanation

Substitution of the 337AVD025MGE is determined by strict equivalence across the following parameters:

Primary Equivalence Criteria:

• Capacitance value: 330 µF (exact match required)
• Voltage rating: 25 V (exact match required)
• Tolerance: ±20% (exact match required)
• Package type: Radial, Can - SMD (exact match required)
• Mounting type: Surface Mount (exact match required)
• Operating temperature range: -55°C ~ 105°C (exact match required)
• Lifetime specification: 5000 Hrs @ 105°C (exact match required)
• Polarization: Polar (exact match required)

Secondary Compatibility Parameters:

• Physical dimensions within tolerance for PCB land pattern accommodation
• ESR and ripple current ratings within acceptable operational limits
• Surface mount land size compatibility

The ATB337M025 meets all primary equivalence criteria and is therefore classified as a direct substitute.

Electrical Performance: The ATB337M025 demonstrates improved electrical characteristics with lower ESR (640 mOhm versus 800 mOhm at 120 Hz) and higher ripple current capability at low frequency (595 mA versus 425 mA at 120 Hz), resulting in reduced heat generation and improved thermal performance in equivalent applications.

Physical Compatibility: The ATB337M025 maintains compatible physical dimensions and surface mount land pattern compatibility with the 337AVD025MGE, supporting direct PCB layout substitution with minimal or no design modification.

Frequently Asked Questions (FAQ)

Q: Can the ATB337M025 be used as a direct replacement for the 337AVD025MGE on existing PCBs?

A: Yes. Both components share identical capacitance (330 µF), voltage rating (25 V), tolerance (±20%), operating temperature range (-55°C ~ 105°C), and lifetime specification (5000 Hrs @ 105°C). Physical dimensions are compatible, with the ATB337M025 height (0.413" maximum) fitting within the 337AVD025MGE footprint (0.417" maximum). Surface mount land patterns are compatible for standard reflow assembly processes.

Q: What are the electrical differences between these two parts?

A: The ATB337M025 exhibits lower ESR at 120 Hz (640 mOhm versus 800 mOhm) and higher ripple current capability at low frequency (595 mA versus 425 mA at 120 Hz). Both components maintain identical ripple current at 100 kHz (850 mA). These differences result in improved thermal performance and reduced voltage ripple in the ATB337M025.

Q: Is the ATB337M025 suitable for new product designs?

A: Yes. The ATB337M025 is in active production status and is ROHS3 compliant, making it appropriate for new designs requiring current regulatory compliance and long-term component availability.

Q: Are there any package or mounting differences?

A: Both components use identical surface mount radial can packaging and mounting type. The ATB337M025 surface mount land size is 0.406" L x 0.417" W compared to 0.406" L x 0.406" W for the 337AVD025MGE. This minor variation is within standard PCB design tolerances and does not require design modification.

Q: What is the moisture sensitivity level for both components?

A: Both the 337AVD025MGE and ATB337M025 are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or assembly processes.
