MVH35VC33RMF80TP Equivalent & Substitute Parts

Part Overview

The MVH35VC33RMF80TP is a 33 µF, 35 V aluminum electrolytic capacitor manufactured by Chemi-Con in the MVH series. This component is classified as obsolete and operates across a temperature range of -40°C to 125°C with a rated lifetime of 1000 hours at 125°C. The part is designed for general-purpose applications requiring surface-mount radial can packaging with polar configuration.

Due to its obsolete product status, equivalent and substitute parts from active manufacturers are necessary for ongoing production, maintenance, and new design implementations. Substitute components must maintain electrical compatibility while meeting current RoHS and automotive qualification standards where applicable.

Tolerance: ±20% (exact match required)
Voltage Rating: 35 V minimum (equal or higher voltage acceptable)
Package / Case: Radial, Can - SMD (exact match required)
Surface Mount Land Size: 6.60 mm x 6.60 mm (exact match required)
Polarization: Polar (exact match required)
Operating Temperature Range: -40°C to 125°C (exact match required)
Mounting Type: Surface Mount (exact match required)

Secondary Performance Parameters:

ESR (Equivalent Series Resistance): Lower values indicate improved performance
Lifetime @ 125°C: Extended lifetime indicates improved reliability
Ripple Current Capability: Higher values indicate greater current handling capacity

Substitute parts are grouped into three categories:

Category 1 - Direct Equivalents (35V Rating): Parts with identical 35 V voltage rating, same physical dimensions, and matching electrical specifications. These provide direct replacement capability.

Category 2 - Voltage Upgrades (50V Rating): Parts with elevated 50 V voltage rating while maintaining 33 µF capacitance and identical physical footprint. These provide enhanced voltage margin and are electrically compatible in 35 V applications.

Category 3 - Performance Upgrades: Parts with improved ESR characteristics, extended lifetime ratings, or enhanced ripple current capability while maintaining core electrical and mechanical compatibility.

Engineering Selection Recommendations

For Direct Replacement (Same Voltage, Same Footprint):

EMVH350ARA330MF80G (Chemi-Con) is the primary direct equivalent. This part maintains the 35 V rating, 33 µF capacitance, and 7.70 mm seated height of the original MVH35VC33RMF80TP. The EMVH350ARA330MF80G is ROHS3 compliant, carries active product status, and includes automotive qualification. ESR is improved to 900 mΩ @ 100 kHz compared to the original 2.3 Ω @ 120 Hz specification.

For Automotive Applications with Enhanced Reliability:

EDT336M035S9HAA (KEMET) and 35THV33M6.3X8 (Rubycon) both provide AEC-Q200 automotive qualification. The 35THV33M6.3X8 offers extended lifetime of 2000 hours at 125°C and reduced ESR of 700 mΩ @ 100 kHz. Both parts are ROHS3 compliant and active products. Physical height increases to 8.00 mm, requiring PCB layout verification.

For Voltage Margin Enhancement:

EMVH500ARA330MF80G (Chemi-Con) and 50THV33M6.3X8 (Rubycon) provide 50 V rating while maintaining 33 µF capacitance. These parts are suitable for applications requiring voltage headroom above the 35 V nominal specification. Both are ROHS3 compliant and active. The 50THV33M6.3X8 includes AEC-Q200 automotive qualification and 2000-hour lifetime rating.

For Legacy System Compatibility:

UCZ1V330MCS1GS (Nichicon) provides 35 V rating with improved ESR of 450 mΩ @ 100 kHz and 2000-hour lifetime. This part carries "Not For New Designs" status but remains available for existing production support. Physical height is 8.00 mm.

Compliance Considerations:

All substitute parts listed are ROHS3 compliant, addressing the non-compliant status of the original MVH35VC33RMF80TP. Parts with automotive qualification (EDT336M035S9HAA, 35THV33M6.3X8, 50THV33M6.3X8) include AEC-Q200 certification suitable for automotive applications.

Frequently Asked Questions (FAQ)

Q: Can EMVH500ARA330MF80G (50V) be used in place of MVH35VC33RMF80TP (35V)?

A: Yes. The 50 V rated part is electrically compatible in 35 V applications. Higher voltage rating provides additional safety margin. Physical height increases from 7.70 mm to 8.00 mm; verify PCB layout clearance before substitution.

Q: What is the difference between EDT336M035A9HAA and EDT336M035S9HAA?

A: Both parts are 33 µF, 35 V KEMET EDT series capacitors with identical electrical specifications. EDT336M035S9HAA includes AEC-Q200 automotive qualification; EDT336M035A9HAA does not. EDT336M035S9HAA is recommended for automotive applications.

Q: Why do some substitute parts have 8.00 mm or 8.20 mm height instead of 7.70 mm?

A: Height variation reflects different internal construction and performance characteristics. Parts with 8.00 mm or 8.20 mm height typically offer improved ESR, extended lifetime, or enhanced ripple current capability. Verify PCB layout accommodates the increased height before selection.

Q: Are Nichicon UCZ series parts suitable for new designs?

A: Nichicon UCZ1V330MCS1GS and UCZ1H330MCS6GS carry "Not For New Designs" product status. These parts are available for legacy system support and existing production continuity but should not be selected for new product development. Use EMVH350ARA330MF80G, EDT336M035S9HAA, or 35THV33M6.3X8 for new designs.

Q: What does ESR (Equivalent Series Resistance) indicate?

A: ESR represents the internal resistance of the capacitor at specified frequency. Lower ESR values indicate reduced heat generation and improved performance under ripple current conditions. The original MVH35VC33RMF80TP specifies 2.3 Ω @ 120 Hz; substitute parts typically offer 450 mΩ to 2000 mΩ @ 100 kHz, representing significant performance improvement.

Q: Is RoHS3 compliance mandatory for substitution?

A: All listed substitute parts are ROHS3 compliant. The original MVH35VC33RMF80TP is RoHS non-compliant. For applications subject to RoHS regulations, ROHS3 compliant substitutes are required. Verify regulatory requirements for your specific application.

Q: What is the significance of AEC-Q200 automotive qualification?

A: AEC-Q200 certification indicates the part meets automotive industry reliability and performance standards. Parts with this qualification (EDT336M035S9HAA, 35THV33M6.3X8, 50THV33M6.3X8) are suitable for automotive applications requiring formal qualification documentation.

Q: Can I use a 33 µF capacitor with different tolerance (e.g., ±10%) as a substitute?

A: No. Tolerance is a critical parameter. The MVH35VC33RMF80TP specifies ±20% tolerance. Substitutes must maintain ±20% tolerance to ensure circuit performance and compliance with design specifications. All listed substitute parts maintain ±20% tolerance.

Q: What is MSL (Moisture Sensitivity Level) and why is it important?

A: MSL indicates moisture sensitivity during storage and handling. All listed parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Parts can be stored and handled without special moisture control measures.

Q: Are the surface mount land sizes identical across all substitute parts?

A: Yes. All substitute parts maintain 6.60 mm x 6.60 mm surface mount land size, ensuring PCB footprint compatibility. Physical case diameter remains 6.30 mm across all parts.
