Substitute Part Grouping Explanation

Substitution of the 476SMH035M is determined by strict equivalence in the following critical parameters:

Electrical Equivalence:

• Capacitance value: 47 µF (exact match required)
• Voltage rating: 35 V (minimum, equal or higher acceptable)
• Tolerance: ±20% (matching tolerance band)
• Polarization: Polar (must match)

Mechanical Equivalence:

• Package type: Radial, Can - SMD (exact match required)
• Physical dimensions: 0.248" Dia (6.30mm) and 0.240" Height (6.10mm) (exact match required)
• Surface mount land size: 0.260" L × 0.260" W (6.60mm × 6.60mm) (exact match required)
• Mounting type: Surface Mount (exact match required)

Environmental & Compliance Equivalence:

• Operating temperature range: -55°C to 105°C (minimum requirement)
• RoHS3 compliance (required)
• MSL rating: 1 (Unlimited) (acceptable)

Substitute parts must satisfy all electrical, mechanical, and compliance criteria. Performance parameters such as ESR, ripple current ratings, and lifetime specifications may vary within acceptable engineering margins for the application category.

Engineering Selection Recommendations

The EEE-FK1V470P from Panasonic Electronic Components is a direct substitute for the 476SMH035M based on equivalence in all critical electrical, mechanical, and compliance parameters. Both components are active products with ROHS3 compliance and MSL rating 1 (Unlimited).

Selection Basis:

The substitute part matches the main part in capacitance (47 µF), voltage rating (35 V), tolerance (±20%), package configuration (Radial, Can - SMD), physical dimensions (0.248" Dia × 0.240" Height), surface mount land size (0.260" L × 0.260" W), operating temperature range (-55°C to 105°C), and polarization (Polar).

The EEE-FK1V470P carries AEC-Q200 automotive qualification, which provides additional reliability assurance beyond general purpose applications. The substitute part demonstrates superior performance characteristics in lifetime (2000 hours at 105°C versus 1000 hours) and ripple current ratings (180 mA at 120 Hz and 240 mA at 100 kHz versus 80 mA and 120 mA respectively), making it suitable for applications requiring enhanced thermal and electrical stress tolerance.

Both components are available in active production status, ensuring supply chain continuity and long-term availability.

Frequently Asked Questions (FAQ)

Q: Can the EEE-FK1V470P replace the 476SMH035M in existing designs?

A: Yes. The EEE-FK1V470P is electrically and mechanically equivalent to the 476SMH035M. Both components have identical capacitance (47 µF), voltage rating (35 V), tolerance (±20%), physical dimensions, and surface mount land pattern. No PCB redesign or circuit modification is required.

Q: Are there differences in packaging between these two parts?

A: The 476SMH035M is supplied in standard packaging, while the EEE-FK1V470P is supplied in Tape & Reel (TR) format. Both components use identical surface mount package geometry (Radial, Can - SMD) with the same land size (0.260" L × 0.260" W). Tape & Reel packaging is standard for high-volume surface mount assembly and does not affect component performance or compatibility.

Q: What is the significance of the AEC-Q200 rating on the EEE-FK1V470P?

A: AEC-Q200 is an automotive qualification standard that certifies the component for use in automotive applications. While the 476SMH035M is rated for general purpose applications, the EEE-FK1V470P meets stricter automotive reliability and testing requirements. This qualification does not restrict use in non-automotive applications; it indicates additional quality assurance.

Q: Do the different lifetime ratings affect substitution suitability?

A: The EEE-FK1V470P has a rated lifetime of 2000 hours at 105°C, compared to 1000 hours for the 476SMH035M. This difference indicates the substitute part has enhanced thermal endurance. For applications operating at or near 105°C, the substitute part provides extended service life. For applications operating at lower temperatures, both parts exceed typical design requirements.

Q: Are the ripple current differences significant?

A: The EEE-FK1V470P supports higher ripple current ratings (180 mA at 120 Hz and 240 mA at 100 kHz) compared to the 476SMH035M (80 mA at 120 Hz and 120 mA at 100 kHz). This indicates the substitute part can handle greater AC stress. For applications within the 476SMH035M ripple current specifications, both parts are suitable. For applications requiring higher ripple current handling, the substitute part is preferred.

Q: Are both parts RoHS compliant?

A: Yes. Both the 476SMH035M and EEE-FK1V470P are ROHS3 compliant and carry MSL rating 1 (Unlimited), indicating no moisture sensitivity restrictions during storage and handling.

Q: What is the operating temperature range for both parts?

A: Both components operate across the identical temperature range of -55°C to 105°C, ensuring thermal compatibility in all specified operating conditions.
