Substitute Part Grouping Explanation

Substitution of the MVA50VC22RMF55TP is determined by strict equivalence in the following electrical and mechanical parameters:

Critical Matching Parameters:

Capacitance: 22 µF (exact match required)
Voltage Rating: 50 V (exact match required)
Tolerance: ±20% (exact match required)
Polarization: Polar (exact match required)
Mounting Type: Surface Mount (exact match required)
Package / Case: Radial, Can - SMD (exact match required)
Physical Dimensions: 0.248" Dia (6.30mm) with compatible height and land size
Operating Temperature Range: Minimum -40°C to 85°C (upgrades to higher temperature ratings are acceptable)
Lifetime @ Temperature: 2000 Hrs @ 85°C minimum (upgrades to higher temperature lifetimes are acceptable)
MSL Rating: 1 (Unlimited) (exact match required)

Substitute parts are grouped into three categories: parametric equivalents, direct manufacturers, and upgrades. Parametric equivalents share identical electrical specifications with the main part. Direct manufacturers provide functionally equivalent components from alternative suppliers. Upgrades offer enhanced performance characteristics such as extended temperature ratings or improved ESR specifications while maintaining backward compatibility.

Engineering Selection Recommendations

Parametric Equivalent (Same Specifications):

EMVA500ADA220MF55G from Chemi-Con is a parametric equivalent offering identical electrical and thermal specifications to the MVA50VC22RMF55TP. This part carries Last Time Buy status and is ROHS3 compliant, providing a direct replacement path from the same manufacturer with improved regulatory compliance.

Direct Manufacturer Alternatives (Active Status):

226SML050M (Cornell Dubilier / Illinois Capacitor), EDK226M050A9GAA (KEMET), and EDK226M050S9GAA (KEMET) are active production parts meeting all critical electrical and mechanical parameters. These components are ROHS3 compliant and available in quantity. The EDK226M050S9GAA variant includes AEC-Q200 automotive qualification. Height differences of 0.012" (0.30mm) and 0.017" (0.45mm) respectively are within typical PCB layout tolerances for surface mount applications.

Upgrade Options (Enhanced Performance):

EDH226M050A9GAA, EDH226M050S9GAA, and EEV226M050S9GAA from KEMET provide extended operating temperature ranges and improved lifetime ratings at elevated temperatures. EDH226M050S9GAA includes AEC-Q200 automotive qualification. EEV226M050S9GAA offers the widest operating temperature range (-55°C to 105°C) and lowest ESR specification (2 Ohm @ 100kHz). These upgrades maintain backward compatibility while providing enhanced thermal performance for demanding applications.

Frequently Asked Questions (FAQ)

Q: Can I use EDH226M050S9GAA as a direct replacement for MVA50VC22RMF55TP?

A: Yes. EDH226M050S9GAA meets all critical electrical parameters (22 µF, 50 V, ±20% tolerance) and physical mounting requirements. The height difference of 0.017" (0.45mm) is within standard PCB layout tolerances. The extended temperature rating (105°C vs. 85°C) and improved lifetime at elevated temperature provide enhanced performance without compromising compatibility.

Q: What is the difference between EDK226M050A9GAA and EDK226M050S9GAA?

A: Both parts are from KEMET's EDK series with identical electrical specifications and dimensions. The primary difference is that EDK226M050S9GAA includes AEC-Q200 automotive qualification, making it suitable for automotive applications. EDK226M050A9GAA is rated for general purpose applications.

Q: Is the height difference between MVA50VC22RMF55TP (0.205") and substitute parts (0.217" to 0.222") significant?

A: The height differences range from 0.012" to 0.017" (0.30mm to 0.45mm). These variations are within standard PCB design tolerances for surface mount components and do not typically require layout modifications. Verify clearance in your specific application if height-constrained space is a design consideration.

Q: Why should I choose EEV226M050S9GAA over other substitutes?

A: EEV226M050S9GAA offers the lowest ESR specification (2 Ohm @ 100kHz), widest operating temperature range (-55°C to 105°C), and highest ripple current rating at high frequency (70 mA @ 100 kHz). These characteristics make it suitable for high-performance and automotive applications requiring superior thermal and electrical performance.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed are ROHS3 compliant, supporting transition from the RoHS non-compliant MVA50VC22RMF55TP to current regulatory standards.

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

A: Active status indicates ongoing production and long-term availability. Last Time Buy status indicates the manufacturer will cease production after a specified date, with limited remaining inventory. For new designs, prioritize Active status parts (226SML050M, EDK226M050A9GAA, EDK226M050S9GAA, EDH226M050A9GAA, EDH226M050S9GAA, EEV226M050S9GAA) to ensure long-term supply continuity.

Q: Can I use 50SEV22M6.3X5.5 from Rubycon as a substitute?

A: Yes. 50SEV22M6.3X5.5 meets all critical electrical and mechanical parameters. It includes AEC-Q200 automotive qualification and is ROHS3 compliant. However, it carries Last Time Buy status, limiting future availability. For new designs, consider Active status alternatives.

Q: What packaging options are available for these substitutes?

A: Substitute parts are available in Cut Tape (CT) and Tape & Reel (TR) packaging. EMVA500ADA220MF55G is supplied in Cut Tape. Most other substitutes are supplied in Tape & Reel format, which is standard for high-volume surface mount assembly. Verify packaging requirements with your procurement process.
