MVY25VC33RMF55TP Equivalent & Substitute Parts

Part Overview

The MVY25VC33RMF55TP is a 33 µF, 25 V aluminum electrolytic capacitor in surface mount radial can package manufactured by Chemi-Con. This component is classified as obsolete, with 1083 pieces currently in stock. The part operates across a temperature range of -55°C to 105°C with a rated lifetime of 1000 hours at 105°C, suitable for general-purpose applications requiring stable capacitance and low impedance characteristics.

Due to obsolete product status, equivalent and substitute parts from active manufacturers provide continuity for new designs and ongoing production requirements. Substitute selection is based on matching capacitance (33 µF), voltage rating (25 V or higher), tolerance (±20%), package dimensions, surface mount compatibility, and thermal performance specifications.

Frequently Asked Questions (FAQ)

Q: Can EMVY350ARA330MF55G (35 V) be used in place of MVY25VC33RMF55TP (25 V)?

A: Yes. The 35 V rated part is electrically compatible in 25 V applications. Higher voltage rating provides additional design margin without affecting circuit operation. All other parameters (capacitance, tolerance, package, temperature range) are identical.

Q: What is the significance of height differences between substitute parts?

A: The original MVY25VC33RMF55TP has a maximum seated height of 5.20mm. Substitute parts range from 5.20mm to 5.65mm. Height differences of 0.30mm to 0.45mm may affect PCB layout clearance and component placement. Verify available vertical space before selection.

Q: Why do some substitutes have different impedance values?

A: Impedance variation reflects different internal construction and materials. Lower impedance (0.520 Ohms for KEMET EEV series, 0.850 Ohms for Cornell Dubilier AVEZ series) indicates better high-frequency performance and lower ESR. Original part specifies 1 Ohm impedance. Lower impedance substitutes provide performance improvement.

Q: What is the difference between EEV336M025A9GAA and EEV336M025S9GAA?

A: Both parts are electrically identical (33 µF, 25 V, 2000 Hrs @ 105°C, 0.520 Ohms impedance). Primary difference is packaging: EEV336M025A9GAA is supplied in Tape & Reel (TR), while EEV336M025S9GAA is supplied in Cut Tape (CT). EEV336M025S9GAA includes AEC-Q200 automotive qualification rating.

Q: Are Last Time Buy parts suitable for new designs?

A: Last Time Buy status indicates the manufacturer will not produce additional quantities beyond current inventory. These parts (25SZV33M6.3X5.5, 25SKV33M6.3X5.5) are suitable for production continuation of existing designs but not recommended for new product development. Active status parts are preferred for new designs.

Q: What does ROHS3 compliance mean for this application?

A: ROHS3 compliance indicates the part meets Restriction of Hazardous Substances Directive requirements, restricting lead and other hazardous materials. The original MVY25VC33RMF55TP is RoHS non-compliant. All recommended substitutes are ROHS3 compliant, meeting current environmental and regulatory standards.

Q: Can surface mount land size differences affect PCB compatibility?

A: All substitute parts maintain identical surface mount land size of 0.260" L x 0.260" W (6.60mm x 6.60mm), matching the original part. PCB footprints are directly compatible without modification.

Q: Which substitute offers the best ripple current performance?

A: AVEZ336M25D16T-F (Cornell Dubilier Electronics) provides the highest ripple current at 100 kHz: 170 mA. EEV336M025A9GAA and EEV336M025S9GAA (KEMET) provide 240 mA @ 100 kHz. Original part specifies 140 mA @ 100 kHz. Higher ripple current capability indicates better performance in high-frequency switching applications.

Q: Is inventory availability a factor in part selection?

A: Inventory availability is provided for reference. UWT1E330MCL1GB (Nichicon) has the highest inventory at 11893 pieces. EMVY250ARA330MF55G (Chemi-Con parametric equivalent) has 6624 pieces. Availability should be verified with suppliers for production requirements.
