Key Parameters

Substitute Part Grouping Explanation

Substitution of the APMA200ARA470MF30S is determined by the following critical parameters:

Primary Matching Criteria:

• Capacitance value: 47 µF (exact match required)
• Capacitor type: Aluminum polymer (maintains electrical characteristics)
• Tolerance: ±20% (standard tolerance class)
• Operating temperature range: -55°C ~ 105°C (functional envelope)
• Lifetime rating: 5000 Hrs @ 105°C (reliability specification)
• RoHS3 compliance (regulatory requirement)

Allowable Variation:

• Voltage rating: Substitute parts rated at 25 V or higher are acceptable, as they provide superior voltage margin while maintaining backward compatibility in 20 V applications
• ESR: Lower ESR values (30 mOhm vs. 50 mOhm) are acceptable, as they improve performance characteristics
• Package footprint: Variations in physical dimensions are acceptable provided the mounting type remains surface mount and land pattern compatibility is verified

The substitute part 25SVPF47M meets all primary matching criteria and allowable variations.

Parameter Comparison

Engineering Selection Recommendations

The 25SVPF47M from Panasonic Electronic Components is a qualified substitute for the obsolete APMA200ARA470MF30S based on the following engineering factors:

Electrical Compatibility: The substitute part maintains identical capacitance (47 µF) and tolerance (±20%), with a higher voltage rating (25 V vs. 20 V) that provides additional design margin. The lower ESR (30 mOhm vs. 50 mOhm) represents an improvement in performance characteristics. Both parts share identical operating temperature ranges (-55°C ~ 105°C) and lifetime ratings (5000 Hrs @ 105°C).

Regulatory Compliance: Both the main part and substitute are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Product Availability: The substitute part carries active product status with 9300 units in stock, ensuring long-term procurement viability compared to the obsolete main part (829 units remaining).

Physical Integration: Package footprint differences exist between the nonstandard SMD main part and the radial can SMD substitute. PCB layout verification is required to confirm land pattern compatibility and mounting clearance.

Frequently Asked Questions (FAQ)

Q: Can the 25SVPF47M directly replace the APMA200ARA470MF30S without circuit modification?

A: Electrical substitution is valid based on matching capacitance, tolerance, temperature range, and lifetime specifications. However, physical package differences (nonstandard SMD vs. radial can SMD) require PCB layout verification. The higher voltage rating (25 V) and lower ESR (30 mOhm) of the substitute are compatible with 20 V circuit designs.

Q: What is the significance of the voltage rating difference (20 V vs. 25 V)?

A: The substitute part's 25 V rating exceeds the main part's 20 V specification, providing additional voltage margin. This is acceptable for backward compatibility in applications designed for 20 V operation. The substitute will not degrade performance in such applications.

Q: Are there any thermal performance differences between these parts?

A: Both parts share identical lifetime ratings (5000 Hrs @ 105°C) and operating temperature ranges (-55°C ~ 105°C). The substitute's lower ESR (30 mOhm vs. 50 mOhm) may result in reduced self-heating under ripple current conditions.

Q: What does the ESR difference (50 mOhm vs. 30 mOhm) mean for circuit performance?

A: ESR (Equivalent Series Resistance) directly affects impedance and voltage ripple characteristics. The substitute's lower ESR provides superior high-frequency ripple current handling (2.8 A @ 100 kHz vs. 2 A @ 100 kHz), resulting in lower voltage drop and reduced thermal dissipation.

Q: Is the package footprint change a critical concern?

A: Package differences require PCB layout verification. The main part uses a nonstandard SMD package (7.00mm x 7.00mm), while the substitute uses a radial can SMD package (6.30mm diameter). Land pattern compatibility and mounting clearance must be confirmed before implementation.

Q: Why is the main part classified as obsolete?

A: Obsolescence indicates the manufacturer has discontinued production. The substitute part's active status ensures continued availability and supply chain stability for future procurement cycles.
