Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Same Electrical Specifications):

UUX1H220MCL1GS (Nichicon) is the primary direct equivalent. This part maintains identical capacitance (22 µF), voltage rating (50 V), tolerance (±20%), and lifetime (2000 Hrs @ 105°C). The part is currently active and available in high volume (111,300 pcs in stock). Operating temperature range extends to -55°C, providing enhanced low-temperature performance. Surface mount land size and package dimensions are identical to the original part. RoHS3 compliance and unlimited moisture sensitivity level (MSL 1) align with modern manufacturing standards.

For Upgraded Performance (Higher Voltage Rating):

AFK226M63E16T-F and AFK226M63E16VT-F (Cornell Dubilier Electronics) provide upgraded voltage rating of 63 V while maintaining 22 µF capacitance and ±20% tolerance. Both parts feature significantly reduced ESR (1.2 Ohm @ 100kHz compared to 9.041 Ohm @ 120Hz), improved ripple current handling (90 mA @ 120 Hz), and AEC-Q200 automotive qualification. Operating temperature range extends to -55°C. The primary difference between these two parts is seated height: AFK226M63E16T-F measures 0.256" (6.50mm) while AFK226M63E16VT-F measures 0.268" (6.80mm). Both require modified surface mount land size (0.327" L x 0.374" W) compared to the original 0.327" L x 0.327" W. These parts are suitable for applications requiring higher voltage margin and lower impedance characteristics.

EEE-FK1J220P (Panasonic) offers 63 V rating with identical capacitance and tolerance. This part maintains the original surface mount land size (0.327" L x 0.327" W), eliminating PCB layout modifications. AEC-Q200 certification and active product status ensure long-term availability. Ripple current capability is 90 mA @ 120 Hz with 120 mA @ 100 kHz high-frequency performance.

For Cost-Sensitive Applications (Same Voltage, Reduced Lifetime):

EEE-HA1H220P (Panasonic) maintains 50 V rating and 22 µF capacitance with identical surface mount land size. This part is marked "Not For New Designs" and features reduced lifetime of 1000 Hrs @ 105°C compared to 2000 Hrs. Selection of this part is appropriate only when lifetime requirements are reduced and cost optimization is prioritized. RoHS compliance and AEC-Q200 certification are provided.

Compliance and Certification Considerations:

The original MVK50VC22RMH63TP is RoHS non-compliant. All recommended substitutes (UUX1H220MCL1GS, AFK226M63E16T-F, AFK226M63E16VT-F, EEE-FK1J220P) are RoHS3 compliant, meeting current environmental regulations. The upgrade parts from Cornell Dubilier and Panasonic carry AEC-Q200 automotive qualification, suitable for automotive and industrial applications requiring enhanced reliability standards.

Frequently Asked Questions (FAQ)

Q1: Can UUX1H220MCL1GS directly replace MVK50VC22RMH63TP without PCB modifications?

A: Yes. UUX1H220MCL1GS is a direct equivalent with identical capacitance (22 µF), voltage rating (50 V), tolerance (±20%), lifetime (2000 Hrs @ 105°C), and surface mount land size (0.327" L x 0.327" W). The seated height differs slightly (0.256" vs. 0.248"), but this does not affect electrical performance or standard PCB assembly processes. No design changes are required.

Q2: What is the advantage of using AFK226M63E16T-F or AFK226M63E16VT-F over the direct equivalent?

A: These parts provide higher voltage rating (63 V vs. 50 V), offering increased design margin for voltage transients and overshoot conditions. ESR is significantly reduced (1.2 Ohm @ 100kHz vs. 9.041 Ohm @ 120Hz), resulting in lower impedance and improved high-frequency ripple current handling (120 mA @ 100 kHz). AEC-Q200 automotive qualification provides enhanced reliability certification. The trade-off is modified surface mount land size (0.327" L x 0.374" W), requiring PCB layout adjustment.

Q3: Why does EEE-FK1J220P maintain the original surface mount land size while the Cornell Dubilier parts do not?

A: Surface mount land size is determined by the manufacturer's specific package design and lead frame geometry. Panasonic's FK series maintains the 0.327" L x 0.327" W land size, while Cornell Dubilier's AFK series uses 0.327" L x 0.374" W. Both are valid 22 µF 63 V SMD aluminum electrolytic capacitors in radial can packages, but with different mechanical footprints. PCB design must accommodate the specific land size of the selected part.

Q4: Is EEE-HA1H220P suitable for long-term reliability applications?

A: EEE-HA1H220P features reduced lifetime of 1000 Hrs @ 105°C compared to 2000 Hrs for the original part and other substitutes. This part is marked "Not For New Designs," indicating it is in end-of-life status. Selection is appropriate only for cost-sensitive applications where reduced lifetime is acceptable and long-term supply is not critical. For new designs requiring 2000-hour lifetime, UUX1H220MCL1GS or the upgraded 63 V parts are recommended.

Q5: What is the impact of operating temperature range differences?

A: The original MVK50VC22RMH63TP operates from -40°C to 105°C. Direct equivalent UUX1H220MCL1GS and upgrade parts (AFK226M63E16T-F, AFK226M63E16VT-F, EEE-FK1J220P) extend the lower limit to -55°C. This provides enhanced performance in cold-temperature environments. For applications operating only above -40°C, this difference is not significant. For applications requiring operation below -40°C, the extended range of substitute parts is beneficial.

Q6: Are all substitute parts available in Tape & Reel packaging?

A: Yes. All recommended substitute parts (UUX1H220MCL1GS, AFK226M63E16T-F, AFK226M63E16VT-F, EEE-FK1J220P, EEE-HA1H220P) are supplied in Tape & Reel (TR) packaging, suitable for automated surface mount assembly processes. Moisture Sensitivity Level (MSL) is 1 (Unlimited) for all parts, indicating no special moisture control requirements during storage and handling.

Q7: Which substitute part is recommended for automotive applications?

A: For automotive applications, AFK226M63E16T-F, AFK226M63E16VT-F, or EEE-FK1J220P are recommended. All three parts carry AEC-Q200 automotive qualification and are rated for automotive, bypass, and decoupling applications. These parts provide enhanced reliability standards required for automotive environments. UUX1H220MCL1GS, while active and compliant, does not carry AEC-Q200 certification and is designated for general-purpose applications.

Q8: What is the inventory status of each substitute part?

A: UUX1H220MCL1GS (Nichicon) has the highest inventory availability with 111,300 pcs in stock. EEE-FK1J220P (Panasonic) has 37,865 pcs available. AFK226M63E16VT-F (Cornell Dubilier) has 878 pcs, and AFK226M63E16T-F has 1,981 pcs. EEE-HA1H220P (Panasonic) has 17,759 pcs. For applications requiring immediate large-volume supply, UUX1H220MCL1GS or EEE-FK1J220P are preferred.
