Engineering Selection Recommendations

For Direct Replacement (Same Operating Conditions)

Select EDK476M6R3A9BAA or EDK476M6R3S9BAA when the application requires identical electrical and thermal specifications to the original MVA6.3VC47RMD55TP. Both parts are manufactured by KEMET, maintain the -40°C to 85°C operating range, and provide 2000-hour lifetime at 85°C. The EDK476M6R3S9BAA variant includes AEC-Q200 automotive qualification, suitable for automotive applications. Choose based on packaging requirements: Cut Tape (CT) for EDK476M6R3A9BAA or Tape & Reel (TR) for EDK476M6R3S9BAA.

For Enhanced Thermal Performance (Upgrade Path)

Select EDH476M6R3A9BAA or EDH476M6R3S9BAA when the application can benefit from extended operating temperature range (-40°C to 105°C) and improved thermal stability. These KEMET EDH series components provide the same 47 µF / 6.3 V specifications with 2000-hour lifetime at the elevated 105°C rating. The EDH476M6R3S9BAA includes AEC-Q200 automotive qualification. This upgrade path is recommended for applications subject to higher ambient temperatures or requiring additional reliability margins.

For Maximum Temperature Range and Performance (Premium Upgrade)

Select EEV476M6R3A9BAA or EEV476M6R3S9BAA when the application requires the widest operating temperature range (-55°C to 105°C) and lowest ESR characteristics. The EEV series provides 1.93 Ohm ESR at 100 kHz and superior ripple current handling (63 mA @ 120 Hz, 90 mA @ 100 kHz). The EEV476M6R3S9BAA includes AEC-Q200 automotive qualification. This option is suitable for demanding applications requiring extended temperature performance and low impedance characteristics.

Compliance Considerations

All substitute parts listed are RoHS3 compliant, addressing regulatory requirements that the original obsolete MVA6.3VC47RMD55TP does not meet. All substitute parts maintain MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard handling and storage procedures.

Frequently Asked Questions (FAQ)

Q: Can I use EDK476M6R3S9BAA as a direct replacement for MVA6.3VC47RMD55TP?

A: Yes. The EDK476M6R3S9BAA maintains identical capacitance (47 µF), voltage rating (6.3 V), tolerance (±20%), operating temperature range (-40°C to 85°C), and lifetime rating (2000 Hrs @ 85°C). Physical dimensions are compatible with the same PCB footprint (0.169" L x 0.169" W land size). The maximum height difference (0.222" vs. 0.205") must be verified for clearance in your specific assembly.

Q: What is the difference between EDK and EDH series substitutes?

A: The EDK series maintains the original operating temperature range of -40°C to 85°C with 2000-hour lifetime at 85°C. The EDH series extends the operating range to -40°C to 105°C with 2000-hour lifetime at 105°C, providing enhanced thermal performance for applications subject to higher temperatures or requiring additional reliability margins.

Q: Why should I consider the EEV476M6R3S9BAA over the EDK476M6R3S9BAA?

A: The EEV series offers three advantages: extended operating temperature range (-55°C to 105°C vs. -40°C to 85°C), lower ESR (1.93 Ohm @ 100 kHz), and higher ripple current capability (63 mA @ 120 Hz vs. 36 mA @ 120 Hz). Select EEV when your application requires superior thermal performance, lower impedance, or operation at temperature extremes.

Q: Are there packaging differences I need to consider?

A: Yes. Cut Tape (CT) packaging is suitable for lower-volume applications and manual assembly. Tape & Reel (TR) packaging is optimized for high-volume automated assembly. Digi-Reel® is a Heilind-specific packaging format. Verify your assembly equipment compatibility before selecting packaging type.

Q: Does the height difference between substitute parts affect PCB layout?

A: The original MVA6.3VC47RMD55TP has a maximum seated height of 0.205" (5.20 mm). Most substitutes have a maximum height of 0.222" (5.65 mm), with the Nichicon UWR0J470MCL1GB at 0.217" (5.50 mm). Verify clearance in your specific PCB assembly, particularly for applications with tight vertical constraints or conformal coating requirements.

Q: Are all substitute parts AEC-Q200 qualified?

A: No. Only the S9BAA variants (EDK476M6R3S9BAA, EDH476M6R3S9BAA, EEV476M6R3S9BAA) carry AEC-Q200 automotive qualification. The A9BAA variants do not include this certification. Select S9BAA variants for automotive applications requiring AEC-Q200 compliance.

Q: What is the inventory status of these substitute parts?

A: All listed substitute parts are currently in stock with quantities ranging from 669 to 2628 pieces. The Nichicon UWR0J470MCL1GB has the highest inventory (2628 pcs), while KEMET EDK and EDH variants range from 669 to 963 pieces. Verify current availability with your supplier before finalizing design decisions.
