Substitute Part Grouping Explanation

Substitute parts are classified into three categories based on electrical and mechanical compatibility with the MVK35VC22RMF55TP:

Direct Manufacturer Equivalent (Same Electrical Specifications) Parts that match all critical parameters: 22 µF capacitance, ±20% tolerance, 35 V rated voltage, 1000 hours lifetime at 105°C, identical physical dimensions (0.248" diameter, 0.205" seated height), and surface mount radial can package. These parts are interchangeable at the circuit board level without design modification.

Parametric Equivalent (Same Electrical Specifications, Active Production) Parts manufactured by Chemi-Con in the active Alchip™ MVE and MVY series that maintain identical capacitance, voltage, tolerance, and lifetime specifications. These parts feature improved RoHS3 compliance and represent current production alternatives to the obsolete MVK series.

Upgrade Substitute (Higher Voltage Rating) The EMVE500ARA220MF60G provides 50 V rated voltage while maintaining 22 µF capacitance and ±20% tolerance. This part is suitable for applications where higher voltage margin is acceptable and beneficial for circuit reliability.

Engineering Selection Recommendations

Primary Recommendation: EMVE350ARA220MF55G (Chemi-Con)

The EMVE350ARA220MF55G is the preferred direct replacement for the obsolete MVK35VC22RMF55TP. This part maintains identical electrical specifications (22 µF, 35 V, ±20% tolerance, 1000 hours @ 105°C) and physical dimensions (0.248" diameter, 0.205" seated height). The EMVE350ARA220MF55G is in active production status with ROHS3 compliance, providing long-term supply availability and regulatory compliance. Extended operating temperature range (-55°C to 105°C) offers improved performance margin compared to the original part.

Secondary Recommendation: EMVY350ARA220MF55G (Chemi-Con)

The EMVY350ARA220MF55G from Chemi-Con's Alchip™ MVY series provides equivalent electrical performance with active production status and ROHS3 compliance. This part features improved ripple current capability (56 mA @ 120 Hz versus 40 mA in the original) and extended temperature range (-55°C to 105°C). Identical physical dimensions ensure direct board-level compatibility.

Alternative Recommendation: RSVVS220M1GDC3001U (Elna America)

The RSVVS220M1GDC3001U from Elna America's RVS series matches the original ESR specification (10 Ohm @ 120 Hz) and maintains all critical electrical parameters. This part is in active production with ROHS3 compliance and extended temperature range (-55°C to 105°C). Physical dimensions are compatible with the original footprint.

Upgrade Option: EMVE500ARA220MF60G (Chemi-Con)

For applications where higher voltage margin enhances circuit reliability, the EMVE500ARA220MF60G provides 50 V rated voltage while maintaining 22 µF capacitance and ±20% tolerance. This part is in active production with ROHS3 compliance. Note: Seated height increases to 5.70 mm (versus 5.20 mm original); verify clearance in the application before selection.

Not Recommended for New Designs:

EEE-FC1V220P and EEE-HA1V220P (Panasonic) are marked "Not For New Designs" and should not be selected for new circuit development, despite meeting electrical specifications.

Frequently Asked Questions (FAQ)

Q: Can the EMVE350ARA220MF55G directly replace the MVK35VC22RMF55TP without circuit modification?

A: Yes. The EMVE350ARA220MF55G maintains identical capacitance (22 µF), voltage rating (35 V), tolerance (±20%), lifetime (1000 hours @ 105°C), and physical dimensions (0.248" diameter, 0.205" seated height). The surface mount land size (0.260" x 0.260") is identical. No circuit design changes are required.

Q: What is the difference between the EMVE350ARA220MF55G and EMVY350ARA220MF55G?

A: Both parts are manufactured by Chemi-Con and meet identical electrical specifications. The EMVY350ARA220MF55G is from the Alchip™ MVY series and offers higher ripple current capability (56 mA @ 120 Hz versus unspecified in EMVE350ARA220MF55G). Both are in active production with ROHS3 compliance. Selection between these parts depends on ripple current requirements in the specific application.

Q: Why does the EMVE500ARA220MF60G have a different height (5.70 mm versus 5.20 mm)?

A: The higher voltage rating (50 V versus 35 V) requires different internal construction, resulting in increased seated height. Before selecting this upgrade substitute, verify that the additional 0.50 mm height does not violate clearance constraints in the application.

Q: Are all substitute parts RoHS compliant?

A: The original MVK35VC22RMF55TP is RoHS non-compliant. All recommended active production substitutes (EMVE350ARA220MF55G, EMVY350ARA220MF55G, RSVVS220M1GDC3001U, 226SMH035M) are ROHS3 compliant. This compliance improvement is a significant advantage for new designs and regulatory requirements.

Q: What is the significance of "Last Time Buy" status for the 35SZV22M6.3X5.5?

A: "Last Time Buy" indicates that Rubycon has announced end-of-life for this part. While currently available in inventory, future procurement will not be possible. This part should not be selected for new designs or long-term production requirements.

Q: Can I use the EMVE500ARA220MF60G (50 V) in place of the 35 V rated original part?

A: Yes, from an electrical standpoint. The 50 V rating provides higher voltage margin and is suitable for applications originally designed for 35 V. However, verify that the increased seated height (5.70 mm versus 5.20 mm) does not create clearance issues on the circuit board.

Q: What does ESR (Equivalent Series Resistance) indicate, and why is it important?

A: ESR represents the internal resistance of the capacitor at a specified frequency (120 Hz in these specifications). Lower ESR indicates better high-frequency performance and reduced heat generation under ripple current conditions. The original MVK35VC22RMF55TP specifies 10.548 Ohm @ 120 Hz; the RSVVS220M1GDC3001U matches this specification at 10 Ohm @ 120 Hz.

Q: What is the difference between "Active," "Obsolete," and "Last Time Buy" product status?

A: Active indicates current production with long-term availability. Obsolete indicates discontinued production with no future availability; the original MVK35VC22RMF55TP is obsolete. Last Time Buy indicates announced end-of-life with a final purchase window before discontinuation. For new designs, select only Active status parts.

Q: Are the physical dimensions identical across all substitute parts?

A: No. While all parts share the same 0.248" (6.30 mm) diameter and 0.260" x 0.260" (6.60 mm x 6.60 mm) surface mount land size, seated heights vary: original is 5.20 mm; most substitutes are 5.50 mm; EMVE500ARA220MF60G is 5.70 mm; Panasonic parts are 5.40 mm. Verify clearance before selection.
