Key Parameters

Substitute Part Grouping Explanation

Substitution of the MVA6.3VC821MH10TP is determined by the following critical parameters:

Electrical Compatibility:

• Capacitance value must equal 820 µF
• Voltage rating must be equal to or greater than 6.3 V
• Tolerance must be ±20%
• Polarization must remain polar

Mechanical Compatibility:

• Package type must be Radial, Can - SMD
• Mounting type must be Surface Mount
• Physical diameter must be 0.315" (8.00 mm)
• Physical height must accommodate the 0.394" (10.00 mm) maximum seated height
• Surface mount land size must be 0.327" L x 0.327" W (8.30 mm x 8.30 mm)

Environmental Compatibility:

• Moisture Sensitivity Level must be 1 (Unlimited)
• Operating temperature range must encompass the original -40°C to 85°C specification

The substitute parts identified meet these criteria while offering improved electrical performance characteristics and updated product status classifications.

Engineering Selection Recommendations

EEE-FT1C821UP (Primary Recommendation)

The EEE-FT1C821UP is the preferred substitute for the MVA6.3VC821MH10TP. This part carries an Active product status, indicating current manufacturing and long-term availability. It holds AEC-Q200 automotive qualification and ROHS3 compliance, meeting modern regulatory requirements. The 16 V voltage rating provides margin above the original 6.3 V specification. The improved ESR of 80 mOhm at 100 kHz and extended operating temperature range of -55°C to 105°C deliver enhanced electrical performance. The physical dimensions remain compatible with the original footprint, with a maximum height of 0.413" (10.50 mm) accommodating the original 0.394" (10.00 mm) specification.

EEE-FK1A821SP (Secondary Recommendation)

The EEE-FK1A821SP serves as an alternative substitute with a 10 V voltage rating. This part carries AEC-Q200 qualification and ROHS3 compliance. It is classified as Not For New Designs, indicating limited future availability. The 160 mOhm ESR at 100 kHz and extended temperature range of -55°C to 105°C provide performance improvements over the original part. Physical compatibility is maintained with the same footprint dimensions.

Both substitute parts maintain the 820 µF capacitance, ±20% tolerance, polar configuration, and surface mount radial can package required for direct substitution. The increased voltage ratings and improved ESR characteristics of the substitute parts are compatible with applications designed for the original 6.3 V specification.

Frequently Asked Questions (FAQ)

Q: Can the EEE-FT1C821UP be used as a direct replacement for the MVA6.3VC821MH10TP?

A: Yes. The EEE-FT1C821UP meets all electrical and mechanical compatibility requirements. It maintains the same 820 µF capacitance, ±20% tolerance, and surface mount radial can package. The higher 16 V voltage rating is compatible with circuits designed for 6.3 V operation. Physical dimensions are compatible, with the maximum height of 0.413" (10.50 mm) accommodating the original 0.394" (10.00 mm) specification.

Q: What is the difference between the two substitute parts?

A: The primary difference is voltage rating. The EEE-FT1C821UP is rated at 16 V with 80 mOhm ESR, while the EEE-FK1A821SP is rated at 10 V with 160 mOhm ESR. Both maintain identical capacitance and tolerance. The EEE-FT1C821UP has Active product status, while the EEE-FK1A821SP is Not For New Designs. For new designs, the EEE-FT1C821UP is the preferred choice.

Q: Are there any height clearance concerns with the substitute parts?

A: The substitute parts have a maximum seated height of 0.413" (10.50 mm), compared to the original 0.394" (10.00 mm). This represents a 0.019" (0.50 mm) increase. PCB layout must accommodate this additional height to prevent mechanical interference with adjacent components or enclosure constraints.

Q: Do the substitute parts maintain the same land pattern?

A: Yes. Both substitute parts use the same surface mount land size of 0.327" L x 0.327" W (8.30 mm x 8.30 mm) as the original MVA6.3VC821MH10TP. No PCB redesign is required for land pattern compatibility.

Q: What is the significance of the RoHS3 compliance on the substitute parts?

A: The substitute parts are ROHS3 compliant, meeting current environmental and regulatory standards. The original MVA6.3VC821MH10TP is RoHS non-compliant. For applications subject to RoHS regulations, the substitute parts provide compliance without functional changes.

Q: How do the ESR values compare between the original and substitute parts?

A: The original part has 707 mOhm ESR at 120 Hz. The EEE-FT1C821UP has 80 mOhm ESR at 100 kHz, and the EEE-FK1A821SP has 160 mOhm ESR at 100 kHz. Lower ESR values reduce heat generation and improve ripple current handling. The substitute parts deliver superior ESR performance.

Q: Are the substitute parts suitable for automotive applications?

A: Both substitute parts carry AEC-Q200 qualification, indicating suitability for automotive applications. The original MVA6.3VC821MH10TP is rated for general purpose applications without automotive qualification.

Q: What is the Moisture Sensitivity Level significance?

A: Both the original and substitute parts have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions. These parts do not require special moisture control during storage or handling.
