Engineering Selection Recommendations

For Automotive Applications with AEC-Q200 Requirement:

Select from 50TZV47M6.3X8 (Rubycon), AFK476M50X16T-F (Cornell Dubilier Electronics), UCD1H470MCL1GS (Nichicon), EEE-FK1H470XP (Panasonic), or UUD1H470MCL1GS (Nichicon). These parts carry AEC-Q200 certification and active product status, ensuring long-term availability and compliance with automotive qualification standards.

For General-Purpose Applications without Automotive Certification:

Select from 865060645008 (Würth Elektronik), 865080645012 (Würth Elektronik), or UWD1H470MCL1GS (Nichicon). These parts meet all electrical and mechanical parameters with active product status and ROHS3 compliance.

Height Constraint Consideration:

If PCB layout requires minimum height, 865060645008, 865080645012, and UWD1H470MCL1GS maintain the original 0.303" (7.70mm) seated height. All other substitutes have increased height of 0.315" (8.00mm) or 0.323" (8.20mm).

Ripple Current Performance:

50TZV47M6.3X8, AFK476M50X16T-F, and UCD1H470MCL1GS maintain the original 195 mA ripple current specification. UUD1H470MCL1GS, 865060645008, and UWD1H470MCL1GS provide 185 mA. 865080645012 provides enhanced ripple current at 230 mA.

RoHS Compliance:

All substitute parts are ROHS3 compliant, addressing the non-compliant status of the original MZA50VC47RMF80TP.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a different height?

A: Height differences must be evaluated against PCB layout constraints. The original part measures 0.303" (7.70mm). Substitutes with 0.315" (8.00mm) or 0.323" (8.20mm) height require verification of available clearance. Parts 865060645008, 865080645012, and UWD1H470MCL1GS maintain the original height.

Q: What is the significance of ripple current specifications?

A: Ripple current rating indicates the maximum AC current the capacitor can handle at specified frequency without exceeding temperature limits. The original part is rated for 195 mA @ 100 kHz. Substitutes with equal or higher ripple current (185 mA minimum) are acceptable for direct replacement.

Q: Are all substitute parts suitable for automotive applications?

A: Parts carrying AEC-Q200 certification are qualified for automotive use: 50TZV47M6.3X8, AFK476M50X16T-F, UCD1H470MCL1GS, EEE-FK1H470XP, and UUD1H470MCL1GS. General-purpose substitutes (865060645008, 865080645012, UWD1H470MCL1GS) are not automotive-qualified.

Q: What does ROHS3 compliance mean?

A: ROHS3 compliance indicates the part meets Restriction of Hazardous Substances Directive requirements, restricting lead, cadmium, mercury, and other hazardous materials. The original MZA50VC47RMF80TP is non-compliant; all substitutes are ROHS3 compliant.

Q: Can I substitute based on capacitance and voltage alone?

A: No. Substitution requires matching all critical parameters: capacitance (47 µF), voltage (50 V), tolerance (±20%), lifetime (2000 Hrs @ 105°C), operating temperature range (-55°C ~ 105°C), package type (Radial, Can - SMD), and mounting type (Surface Mount). Physical dimensions and ripple current must also be verified against design constraints.

Q: What is the difference between impedance values in substitute parts?

A: Impedance affects high-frequency performance and transient response. The original part specifies 680 mOhms. UCD1H470MCL1GS provides lower impedance at 630 mOhms, offering improved high-frequency performance. 865080645012 has slightly higher impedance at 700 mOhms. All values remain within acceptable range for this capacitance and voltage class.

Q: Is the original MZA50VC47RMF80TP still available?

A: The MZA50VC47RMF80TP is classified as obsolete. Inventory of 979 pieces is available, but long-term supply cannot be guaranteed. Transition to an active substitute part is recommended for new designs and ongoing production.
