Frequently Asked Questions (FAQ)

Q: Can EEV226M016A9BAA and EEV226M016S9BAA be used interchangeably with MZA16VC22RMD61TP?

A: Both KEMET parts meet all primary electrical and mechanical substitution criteria: 22 µF capacitance, 16 V rating, ±20% tolerance, 2000 Hrs @ 105°C lifetime, and identical operating temperature range. Both are ROHS3 compliant and carry AEC-Q200 automotive certification. The impedance specification differs (1.93 Ohms versus 1.35 Ohms for the original), which is within acceptable tolerance for general purpose and automotive applications. Both parts are electrically and mechanically interchangeable.

Q: What is the difference between the 16V and 25V/35V rated substitutes?

A: UCM1E220MCL1GS (25V) and UCM1V220MCL1GS (35V) maintain identical capacitance (22 µF), tolerance (±20%), lifetime (2000 Hrs @ 105°C), and operating temperature (-55°C to 105°C) as the original part. The higher voltage rating provides increased safety margin in circuits subject to voltage transients or overvoltage conditions. These parts are backward compatible with 16V designs and can be used as direct substitutes. The higher voltage rating does not degrade performance in 16V applications.

Q: Are there physical dimension differences that affect PCB layout?

A: The original MZA16VC22RMD61TP has a maximum seated height of 5.80 mm. Most substitute parts (EMZA160ARA220MD61G, 16TZV22M4X6.1, AFK226M16B12T-F, UCM1E220MCL1GS, UCM1V220MCL1GS, EEE-FK1C220UR) have a maximum seated height of 6.10 mm, representing a 0.30 mm increase. EEV226M016A9BAA and EEV226M016S9BAA have a maximum seated height of 5.65 mm, which is lower than the original. UCL1C220MCL6GS matches the original height at 5.80 mm. All parts maintain the same 0.157" diameter (4.00 mm) and surface mount land size (0.169" L x 0.169" W / 4.30 mm x 4.30 mm). Height differences are negligible for most PCB designs with standard component spacing.

Q: Which substitute offers the best high-frequency ripple current performance?

A: UCL1C220MCL6GS delivers 160 mA ripple current at 100 kHz, compared to 90 mA for MZA16VC22RMD61TP and all other listed substitutes. This 78% increase in ripple current capacity results from the lower impedance specification (0.85 Ohms versus 1.35 Ohms). UCL1C220MCL6GS is optimal for applications requiring enhanced high-frequency filtering or where ripple current margins are critical.

Q: What is the significance of AEC-Q200 certification on substitute parts?

A: AEC-Q200 is an automotive industry standard qualification for discrete semiconductors and passive components. Parts carrying this certification (EMZA160ARA220MD61G, 16TZV22M4X6.1, AFK226M16B12T-F, EEV226M016S9BAA, EEE-FK1C220UR, UCM1E220MCL1GS, UCM1V220MCL1GS) have undergone rigorous testing for reliability, temperature cycling, vibration, and moisture resistance. These parts are suitable for automotive, industrial, and mission-critical applications. General purpose applications do not require AEC-Q200 certification but benefit from the enhanced reliability assurance.

Q: Is the packaging format (Tape & Reel versus Cut Tape) significant for substitution?

A: Packaging format affects supply chain logistics and handling but does not impact electrical or mechanical performance. MZA16VC22RMD61TP is supplied in standard packaging. Most substitutes are available in Tape & Reel (TR) format for automated assembly. UCL1C220MCL6GS and UCM1V220MCL1GS are available in Cut Tape (CT) and Digi-Reel® formats. Selection should be based on production equipment compatibility and volume requirements rather than electrical equivalence.

Q: Can UCL1C220MCL6GS be used in all applications where MZA16VC22RMD61TP is specified?

A: UCL1C220MCL6GS meets all primary electrical and mechanical substitution criteria and is ROHS3 compliant. The lower impedance (0.85 Ohms versus 1.35 Ohms) and higher ripple current capacity (160 mA @ 100 kHz versus 90 mA) represent performance improvements rather than deviations. This part is suitable for all applications where MZA16VC22RMD61TP is used and offers superior performance in high-frequency filtering applications.
