• Polarization: Polar (exact match required)
• Operating Temperature Range: -40°C ~ 85°C minimum (equal or extended range acceptable)
• Lifetime @ Temperature: 2000 Hrs @ 85°C minimum (equal or extended acceptable)
• Mounting Type: Surface Mount (exact match required)
• Package / Case: Radial, Can - SMD (exact match required)
• Physical Dimensions: 0.197" Dia (5.00mm) and surface mount land size 0.209" L x 0.209" W (5.30mm x 5.30mm) (exact match required)

Acceptable Variation Parameters:

• ESR (Equivalent Series Resistance): May vary; lower ESR values indicate improved performance
• Ripple Current: May vary; higher ripple current ratings indicate enhanced capability
• Height - Seated: Minor variations acceptable within PCB assembly constraints
• RoHS Status: Upgrades to RoHS3 compliant parts are acceptable; downgrades are not
• Product Status: Active parts preferred over obsolete; Last Time Buy acceptable as transition

The substitute parts listed below meet all critical matching parameters and represent direct functional equivalents or performance upgrades.

Parameter Comparison

Engineering Selection Recommendations

Direct Parametric Equivalent (Preferred for Drop-In Replacement):

EMVA250ADA330ME55G (Chemi-Con) is the closest parametric equivalent to MVA25VC33RME55TP. This part maintains identical electrical specifications, operating temperature range, lifetime rating, and physical dimensions. The primary advantage is ROHS3 compliance, addressing regulatory requirements. Product status is Last Time Buy, indicating limited availability; procurement should prioritize this part for near-term requirements.

Active Production Alternatives (Recommended for New Designs):

EDK336M025A9DAA and EDK336M025S9DAA (KEMET, EDK series) are active production parts meeting all critical electrical parameters. Both parts are ROHS3 compliant and feature identical capacitance, voltage, tolerance, and operating temperature specifications. Height is 0.222" (5.65mm) versus 0.205" (5.20mm) for the original part; PCB layout verification is required. EDK336M025S9DAA includes AEC-Q200 automotive qualification, suitable for automotive applications.

Performance Upgrade Options:

EEV336M025A9DAA and EEV336M025S9DAA (KEMET, EEV series) provide enhanced performance characteristics. These parts extend the operating temperature range to -55°C ~ 105°C and increase lifetime rating to 2000 Hrs @ 105°C. Ripple current capability increases to 112 mA @ 120 Hz and 160 mA @ 100 kHz, representing significant performance improvement. Both parts are ROHS3 compliant and active in production. EEV336M025S9DAA includes AEC-Q200 automotive qualification. Height is 0.222" (5.65mm); PCB layout verification is required.

Obsolete Alternative (Not Recommended for New Designs):

UWR1E330MCL1GB (Nichicon, UWR series) meets all critical electrical parameters and is ROHS3 compliant. Product status is obsolete; this part is suitable only for legacy system maintenance or repair where original specifications must be maintained. Height is 0.217" (5.50mm), within acceptable variation range.

Frequently Asked Questions (FAQ)

Q: Can I use EDK336M025A9DAA as a direct replacement for MVA25VC33RME55TP?

A: EDK336M025A9DAA meets all critical electrical parameters: 33 µF capacitance, 25 V voltage rating, ±20% tolerance, -40°C ~ 85°C operating range, and 2000 Hrs @ 85°C lifetime. Physical dimensions are compatible with the same 5.30mm x 5.30mm surface mount land size. The seated height is 0.222" (5.65mm) versus 0.205" (5.20mm) for the original part. Verify PCB clearance for the increased height before implementation.

Q: What is the difference between EDK336M025A9DAA and EDK336M025S9DAA?

A: Both parts are electrically and mechanically identical. EDK336M025S9DAA includes AEC-Q200 automotive qualification and is rated for automotive applications. EDK336M025A9DAA is rated for general purpose applications. Select EDK336M025S9DAA for automotive designs; either part is acceptable for general purpose applications.

Q: Why are the EEV336M parts listed as upgrades rather than direct equivalents?

A: EEV336M025A9DAA and EEV336M025S9DAA exceed the original specifications in three areas: operating temperature range extends to -55°C ~ 105°C (versus -40°C ~ 85°C), lifetime rating increases to 2000 Hrs @ 105°C (versus 2000 Hrs @ 85°C), and ripple current capability increases to 112 mA @ 120 Hz (versus 47 mA @ 120 Hz). These parts are classified as upgrades because they provide enhanced performance while maintaining full backward compatibility with the original electrical specifications.

Q: Is ROHS3 compliance required for my application?

A: ROHS3 compliance is a regulatory requirement in many markets. MVA25VC33RME55TP is RoHS non-compliant. All substitute parts listed except UWR1E330MCL1GB are ROHS3 compliant. Verify regulatory requirements for your target market and select accordingly.

Q: Can I use parts with different ripple current ratings?

A: Ripple current rating indicates the maximum AC current the capacitor can safely handle. Substitute parts with equal or higher ripple current ratings are acceptable. Parts with lower ripple current ratings (such as EDK336M025A9DAA at 42 mA @ 120 Hz versus 47 mA @ 120 Hz for the original) are acceptable if circuit ripple current does not exceed the substitute part's rating. Verify actual circuit ripple current requirements before selection.

Q: What does "Last Time Buy" product status mean?

A: Last Time Buy indicates the manufacturer has announced end-of-life for the product. EMVA250ADA330ME55G is available in limited quantities before production ceases. This part is suitable for near-term production requirements but should not be selected for long-term or high-volume applications. Transition to active production alternatives (EDK or EEV series) for sustained availability.

Q: Are there height restrictions for my PCB?

A: Physical height varies among substitutes. MVA25VC33RME55TP has a maximum seated height of 0.205" (5.20mm). EMVA250ADA330ME55G maintains this height. EDK336M025A9DAA, EDK336M025S9DAA, EEV336M025A9DAA, and EEV336M025S9DAA have a maximum seated height of 0.222" (5.65mm). UWR1E330MCL1GB has a maximum seated height of 0.217" (5.50mm). Verify PCB assembly clearance for parts with increased height.

Q: Which part should I select for a new design?

A: For new designs, select from active production parts: EDK336M025A9DAA (general purpose) or EEV336M025A9DAA (performance upgrade). For automotive applications, select EDK336M025S9DAA or EEV336M025S9DAA. All are ROHS3 compliant, actively manufactured, and provide long-term supply security. EEV series parts provide enhanced performance characteristics suitable for demanding applications.
