Engineering Selection Recommendations

Parametric Equivalent (Direct Replacement): EMVA250ARA220ME55G (Chemi-Con) provides identical electrical and mechanical specifications to the MVA25VC22RME55TP with the advantage of ROHS3 compliance. This part is discontinued at DiGi Electronics but maintains the same 5.20 mm height and 41 mA ripple current rating. Selection is appropriate for applications requiring exact dimensional and electrical compatibility.

Direct Equivalents (Same Voltage Rating, Active Status): EDK226M025A9DAA and EDK226M025S9DAA (KEMET) are active production parts with 25 V rating and 2000 Hrs @ 85°C lifetime. These parts feature slightly increased height (5.65 mm vs. 5.20 mm) and reduced ripple current (35 mA vs. 41 mA). The S9DAA variant includes AEC-Q200 automotive qualification. Selection is appropriate for new designs requiring active component availability and RoHS compliance.

UWR1E220MCL1GB (Nichicon) is an obsolete part with equivalent specifications but offers higher ripple current capability (42 mA). This part is not recommended for new designs due to obsolete status.

Upgraded Substitutes (Enhanced Temperature Rating): EDH226M025A9DAA and EDH226M025S9DAA (KEMET) provide extended operating temperature to 105°C with 2000 Hrs @ 105°C lifetime rating. These parts are suitable for applications requiring enhanced thermal performance. The S9DAA variant includes AEC-Q200 automotive qualification. Height is 5.65 mm; ripple current is reduced to 28 mA.

EEV226M025A9DAA and EEV226M025S9DAA (KEMET) provide the broadest operating temperature range (-55°C to 105°C) with 2000 Hrs @ 105°C lifetime and significantly higher ripple current capability (112 mA). These parts are suitable for demanding thermal and ripple current applications. The S9DAA variant includes AEC-Q200 automotive qualification.

Upgraded Substitutes (Higher Voltage Rating): EDK226M035A9DAA and EDK226M035S9DAA (KEMET) provide 35 V rating with 2000 Hrs @ 85°C lifetime. These parts are suitable for applications requiring voltage margin above the 25 V specification. The S9DAA variant includes AEC-Q200 automotive qualification.

Frequently Asked Questions (FAQ)

Q: Can I use a 35 V rated capacitor in place of a 25 V rated capacitor? A: Yes. A higher voltage rating is a direct upgrade. The EDK226M035A9DAA and EDK226M035S9DAA provide 35 V rating while maintaining all other specifications. This provides additional voltage margin and is electrically compatible.

Q: What is the difference between the A9DAA and S9DAA variants? A: The S9DAA variants include AEC-Q200 automotive qualification and are packaged in Cut Tape (CT) format, while A9DAA variants are standard industrial grade packaged in Tape & Reel (TR) format. Both are electrically identical for the same base part number.

Q: Why is the height specification different between substitute parts? A: The MVA25VC22RME55TP has a maximum seated height of 5.20 mm. Substitute parts from KEMET (EDK, EDH, EEV series) have a maximum seated height of 5.65 mm. This 0.45 mm difference must be verified against PCB layout constraints and clearance requirements before selection.

Q: Can I use an obsolete part as a substitute? A: Obsolete parts (MVA25VC22RME55TP, EMVA250ARA220ME55G, UWR1E220MCL1GB) are not recommended for new designs. Active production parts (EDK226M, EDH226M, EEV226M series from KEMET) are preferred to ensure long-term supply chain continuity.

Q: What does RoHS compliance mean for this capacitor? A: RoHS3 compliance indicates the part meets Restriction of Hazardous Substances regulations. The original MVA25VC22RME55TP is RoHS non-compliant. All substitute parts listed are ROHS3 compliant, making them suitable for applications with RoHS requirements.

Q: How does ripple current affect capacitor selection? A: Ripple current rating determines the maximum AC current the capacitor can handle without exceeding temperature limits. The original part is rated 41 mA @ 120 Hz. Substitute parts range from 28 mA to 112 mA. Selection must ensure the application's ripple current does not exceed the chosen part's rating.

Q: What is the significance of the 2000 Hrs @ 85°C lifetime rating? A: This specifies the capacitor's expected operational life under rated conditions. All listed parts maintain this minimum rating. Upgraded parts (EDH and EEV series) extend this to 2000 Hrs @ 105°C, indicating longer life at elevated temperatures.

Q: Can I use the EEV226M025A9DAA in a -40°C to 85°C application? A: Yes. The EEV226M025A9DAA has an operating temperature range of -55°C to 105°C, which encompasses the -40°C to 85°C requirement. This part is a direct upgrade with extended temperature capability.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) packaging? A: Tape & Reel (TR) packaging is supplied on continuous reels for automated assembly. Cut Tape (CT) is supplied in smaller quantities on tape segments. Both formats are mechanically and electrically identical; selection depends on procurement volume and assembly equipment compatibility.
