MVK35VC33RMH63TP Equivalent & Substitute Parts

Part Overview

The MVK35VC33RMH63TP is a 33 µF, 35 V aluminum electrolytic capacitor manufactured by Chemi-Con in surface mount radial can package. This component is classified as obsolete, indicating it is no longer in active production. The part operates across a temperature range of -40°C to 105°C with a rated lifetime of 2000 hours at 105°C, making it suitable for general-purpose applications requiring stable capacitance and low equivalent series resistance.

Due to its obsolete status, equivalent and substitute parts from active manufacturers are necessary to maintain design continuity and ensure long-term component availability for production and field service applications.

Substitute Part Grouping Explanation

Substitution of the MVK35VC33RMH63TP is determined by the following critical parameters:

Direct Equivalents (Same Voltage Rating - 35V): Direct substitutes maintain the same 33 µF capacitance, ±20% tolerance, and 35 V voltage rating. These parts are pin-compatible and functionally interchangeable without circuit modification. The UUX1V330MCL1GS from Nichicon qualifies as a direct equivalent, offering identical electrical specifications with improved product status (Active) and RoHS3 compliance.

Upgraded Substitutes (Higher Voltage Rating - 50V): Upgraded substitutes increase the voltage rating to 50 V while maintaining 33 µF capacitance and ±20% tolerance. These parts provide enhanced voltage margin and are electrically compatible in applications designed for 35 V operation. Upgraded parts include AFK336M50E16T-F, AFK336M50E16VT-F (Cornell Dubilier Electronics), EEE-FK1H330P (Panasonic), and UCD1H330MCL6GS (Nichicon). These upgrades offer active product status, AEC-Q200 automotive qualification, and RoHS3 compliance.

Similar Substitutes (Same Voltage Rating - 35V, Different Lifetime): Similar substitutes maintain 35 V voltage rating and 33 µF capacitance but differ in thermal lifetime specification. EEE-HA1V330P from Panasonic provides 1000 hours at 105°C (versus 2000 hours for the original part) and carries "Not For New Designs" status, suitable only for legacy system maintenance.

Substitution logic is based strictly on capacitance, tolerance, voltage rating, package dimensions, mounting type, and thermal lifetime specifications. All substitute parts maintain surface mount radial can package configuration with compatible land sizes and MSL rating of 1 (Unlimited).

Engineering Selection Recommendations

For New Designs and Active Production: The UUX1V330MCL1GS (Nichicon) is the primary direct equivalent, offering identical electrical specifications to the MVK35VC33RMH63TP with active product status and RoHS3 compliance. This part maintains the 35 V voltage rating, 33 µF capacitance, ±20% tolerance, and 2000-hour thermal lifetime while extending the operating temperature range to -55°C to 105°C.

For Applications Requiring Enhanced Voltage Margin: The AFK336M50E16T-F, AFK336M50E16VT-F (Cornell Dubilier Electronics), EEE-FK1H330P (Panasonic), and UCD1H330MCL6GS (Nichicon) provide 50 V rated voltage with identical capacitance and tolerance specifications. These upgrades are suitable for circuits designed for 35 V operation and offer AEC-Q200 automotive qualification. All four parts maintain active product status and RoHS3 compliance. Selection between these four parts depends on specific height constraints and land size requirements, as detailed in the parameter comparison table.

For Legacy System Maintenance Only: The EEE-HA1V330P (Panasonic) carries "Not For New Designs" status and provides reduced thermal lifetime (1000 hours at 105°C versus 2000 hours). This part is restricted to field service and repair of existing systems where the original MVK35VC33RMH63TP specification must be maintained.

All recommended substitutes maintain surface mount radial can package configuration, MSL rating of 1 (Unlimited), and compatibility with the original 0.327" L x 0.327" W (8.30mm x 8.30mm) surface mount land size.

Frequently Asked Questions (FAQ)

Q: Can the UUX1V330MCL1GS directly replace the MVK35VC33RMH63TP without circuit modification?

A: Yes. The UUX1V330MCL1GS maintains identical capacitance (33 µF), tolerance (±20%), voltage rating (35 V), thermal lifetime (2000 hours at 105°C), and surface mount package configuration. The part is pin-compatible and functionally interchangeable. The extended operating temperature range (-55°C to 105°C versus -40°C to 105°C) provides additional design margin.

Q: What is the advantage of using a 50 V rated substitute instead of a 35 V equivalent?

A: A 50 V rated substitute provides enhanced voltage margin in the circuit, reducing stress on the capacitor and potentially extending operational lifetime. The AFK336M50E16T-F, AFK336M50E16VT-F, EEE-FK1H330P, and UCD1H330MCL6GS all maintain 33 µF capacitance and ±20% tolerance while offering 50 V voltage rating. These parts are electrically compatible in applications designed for 35 V operation and carry active product status with AEC-Q200 automotive qualification.

Q: Are there physical dimension differences between substitute parts?

A: Yes. While all substitutes maintain the same 8.00mm diameter, seated heights vary between 6.20mm and 6.80mm. The original MVK35VC33RMH63TP has a maximum seated height of 6.30mm. The UUX1V330MCL1GS, AFK336M50E16T-F, EEE-FK1H330P, and UCD1H330MCL6GS all have 6.50mm maximum height. The AFK336M50E16VT-F reaches 6.80mm. Surface mount land sizes remain compatible at 0.327" L x 0.327" W (8.30mm x 8.30mm) for most substitutes, with AFK series parts using 0.327" L x 0.374" W (8.30mm x 9.50mm). Verify PCB layout clearance before final part selection.

Q: What is the difference between the two Cornell Dubilier AFK parts (AFK336M50E16T-F and AFK336M50E16VT-F)?

A: Both parts share identical electrical specifications: 33 µF, 50 V, ±20% tolerance, 2000-hour thermal lifetime, and AEC-Q200 qualification. The primary difference is seated height: AFK336M50E16T-F has 6.50mm maximum height, while AFK336M50E16VT-F reaches 6.80mm. Selection depends on available PCB clearance in the target application.

Q: Why is the EEE-HA1V330P marked "Not For New Designs"?

A: The EEE-HA1V330P carries reduced thermal lifetime specification of 1000 hours at 105°C compared to 2000 hours for the original part and other active substitutes. This reduced lifetime makes it unsuitable for new product designs. It is restricted to field service and repair of legacy systems where the original specification must be maintained.

Q: Are all substitute parts RoHS compliant?

A: The direct equivalent UUX1V330MCL1GS and all upgraded 50 V substitutes (AFK336M50E16T-F, AFK336M50E16VT-F, EEE-FK1H330P, UCD1H330MCL6GS) are RoHS3 compliant. The EEE-HA1V330P is RoHS compliant. The original MVK35VC33RMH63TP is RoHS non-compliant. For applications requiring RoHS compliance, use any of the active substitute parts listed above.

Q: What is the moisture sensitivity level for these capacitors?

A: All substitute parts maintain MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions. The original MVK35VC33RMH63TP also carries MSL 1 rating. These parts do not require special moisture control during storage, handling, or assembly.

Q: Which substitute offers the best availability?

A: Based on provided inventory data, the UCD1H330MCL6GS (Nichicon) has the highest stock level at 4559 pieces, followed by UUX1V330MCL1GS (Nichicon) at 4088 pieces. Both parts are active products with RoHS3 compliance and suitable for new designs.
