Key Parameters

Substitute Part Grouping Explanation

Substitution logic is based on the following criteria:

Direct Equivalents (Same Voltage Rating - 10V):

• Capacitance: 470 µF (exact match)
• Voltage Rating: 10 V (exact match)
• Tolerance: ±20% (exact match)
• Operating Temperature: -55°C to 105°C (exact match)
• Lifetime: 2000 Hrs @ 105°C (exact match)
• Package: Radial, Can - SMD (exact match)
• Physical Dimensions: 0.315" Dia (8.00mm) (exact match)
• Mounting: Surface Mount (exact match)
• Compliance: ROHS3, MSL 1 (exact match)

Direct equivalent parts are EEE-FK1A471AP, EEE-FK1A471P, EMZA100ARA471MHA0G, UCL1A471MNL1GS, and EMVY100ARA471MHA0G. These parts maintain identical electrical and mechanical specifications, differing only in manufacturer and internal design.

Upgrade Substitute (Higher Voltage Rating - 16V):

• Capacitance: 470 µF (exact match)
• Voltage Rating: 16 V (upgrade from 10 V)
• Tolerance: ±20% (exact match)
• Operating Temperature: -55°C to 105°C (exact match)
• Lifetime: 2000 Hrs @ 105°C (exact match)
• Package: Radial, Can - SMD (exact match)
• Physical Dimensions: 0.315" Dia (8.00mm) (exact match)
• Mounting: Surface Mount (exact match)
• Compliance: ROHS3, MSL 1 (exact match)

The AHA477M16F24B-F provides higher voltage margin for circuits operating below 10 V. This part is functionally compatible in any application using the AFK477M10F24B-F where the 16 V rating does not create design conflicts.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Same Electrical Performance):

Select EEE-FK1A471P (Panasonic) or EMZA100ARA471MHA0G (Chemi-Con) as primary alternatives. Both parts maintain identical 10 V voltage rating, 470 µF capacitance, ±20% tolerance, and 2000 hour lifetime at 105°C. EEE-FK1A471P offers the highest inventory availability (3970 pcs) and matches the original ripple current specifications. Both are ROHS3 compliant with MSL 1 rating.

For Voltage Margin Applications:

Select AHA477M16F24B-F (Cornell Dubilier) when circuit design permits higher voltage rating. This upgrade maintains the same manufacturer lineage as the original part, ensuring consistent internal design philosophy. The 16 V rating provides additional safety margin in applications with voltage transients or design headroom requirements. Product status is Active with 997 pcs inventory.

For Low-ESR Applications:

Select UCL1A471MNL1GS (Nichicon) when lower impedance is beneficial. This part provides 80 mOhms impedance (versus 160 mOhms in the original), supporting higher ripple current handling at 100 kHz (850 mA versus 600 mA). Suitable for high-frequency switching applications. Product status is Active with 6263 pcs inventory.

Compliance Verification:

All recommended substitutes maintain ROHS3 compliance and MSL 1 rating. AEC-Q200 automotive qualification is confirmed for AFK477M10F24B-F, AHA477M16F24B-F, EEE-FK1A471AP, and EEE-FK1A471P. Verify AEC-Q200 requirement with Chemi-Con and Nichicon for EMZA100ARA471MHA0G, UCL1A471MNL1GS, and EMVY100ARA471MHA0G if automotive qualification is mandatory.

Frequently Asked Questions (FAQ)

Q: Can I use a 16 V rated capacitor in place of the 10 V AFK477M10F24B-F?

A: Yes. The AHA477M16F24B-F is a direct mechanical and electrical substitute with higher voltage rating. Higher voltage ratings are acceptable in circuits designed for lower voltages. The 16 V part will function identically in 10 V applications. Verify that the 0.402" height (versus 0.413" original) does not create clearance conflicts on your PCB.

Q: What is the difference between EEE-FK1A471AP and EEE-FK1A471P?

A: Both are Panasonic FK series 470 µF 10 V capacitors with identical electrical specifications. The primary difference is packaging: EEE-FK1A471AP is specified for high-temperature reflow applications, while EEE-FK1A471P is general automotive. Both maintain the same physical dimensions, voltage, capacitance, and tolerance. EEE-FK1A471P has higher inventory availability.

Q: Are all substitute parts compatible with the original PCB footprint?

A: Physical dimensions are compatible for all listed substitutes. All parts use 0.315" diameter (8.00mm) can with 0.327" L x 0.327" W or 0.327" L x 0.394" W surface mount land sizes. Verify your PCB pad layout accommodates the land size variation. Height differences range from 0.394" to 0.413" maximum seated height; confirm clearance above the capacitor location.

Q: Which substitute has the lowest ESR?

A: UCL1A471MNL1GS (Nichicon) provides 80 mOhms impedance, the lowest among all listed parts. The original AFK477M10F24B-F and direct equivalents EEE-FK1A471AP and EEE-FK1A471P specify 160 mOhms. Lower ESR reduces voltage ripple and heat generation in high-frequency applications.

Q: Do all substitutes support the full -55°C to 105°C operating temperature range?

A: Yes. All listed substitute parts maintain -55°C to 105°C operating temperature range with 2000 hour lifetime rating at 105°C, matching the original AFK477M10F24B-F specification.

Q: Is AEC-Q200 automotive qualification available for all substitutes?

A: AEC-Q200 qualification is confirmed for Cornell Dubilier (AFK477M10F24B-F, AHA477M16F24B-F) and Panasonic (EEE-FK1A471AP, EEE-FK1A471P) parts. Chemi-Con EMZA100ARA471MHA0G and EMVY100ARA471MHA0G, and Nichicon UCL1A471MNL1GS do not list AEC-Q200 in provided specifications. Verify automotive qualification directly with manufacturers if required for your application.

Q: What is the difference between EMZA100ARA471MHA0G and EMVY100ARA471MHA0G?

A: Both are Chemi-Con Alchip™ series 470 µF 10 V capacitors. EMZA100ARA471MHA0G (MZA series) provides 160 mOhms impedance and 600 mA ripple current at 100 kHz. EMVY100ARA471MHA0G (MVY series) provides 300 mOhms impedance and 450 mA ripple current at 100 kHz. EMZA is the higher-performance option for demanding ripple current applications.
