Frequently Asked Questions (FAQ)

Q: Can RFS-6V470MF3#5 be used as a direct replacement for RFS-6V470ME3#5?

A: RFS-6V470MF3#5 shares identical electrical specifications (47 µF, 6.3 V, ±20% tolerance, 1000 Hrs @ 85°C). However, lead spacing differs (0.098" vs 0.079") and height is reduced (0.433" vs 0.492"). Substitution requires PCB layout modification to accommodate the different footprint. Verify pad spacing and component clearance before implementation.

Q: What is the primary advantage of upgrading to EEU-FC1C470?

A: EEU-FC1C470 is an Active product with extended operating temperature range (-55°C to 105°C vs -40°C to 85°C), higher rated voltage (16 V vs 6.3 V), and significantly increased ripple current capacity (113.8 mA @ 120 Hz vs 65 mA @ 120 Hz). It maintains identical mechanical compatibility (0.079" lead spacing, 0.472" height) and provides superior performance margins. AEC-Q200 rating enables automotive applications.

Q: Are there Active product alternatives available?

A: Yes. EEU-FC1C470 (Panasonic) and SEK470M010ST (Cornell Dubilier) are both Active products. EEU-FC1C470 offers 16 V rating with extended temperature range. SEK470M010ST offers 10 V rating with 2000 Hrs @ 105°C lifetime and specified ESR (6.21 Ohm @ 120 Hz). Both maintain 0.079" lead spacing for direct PCB compatibility.

Q: What is the difference between 1000 Hrs @ 85°C and 2000 Hrs @ 105°C lifetime ratings?

A: These represent different thermal stress conditions. 1000 Hrs @ 85°C indicates the capacitor maintains specified performance for 1000 hours at 85°C ambient temperature. 2000 Hrs @ 105°C indicates 2000 hours at the higher 105°C temperature. Higher temperature ratings with extended hour specifications indicate superior thermal stability and longer operational life under elevated conditions.

Q: Can UFW1E470MDD or UFW1V470MDD be used in place of the original part?

A: Yes. Both parts maintain identical mechanical dimensions (0.079" lead spacing, 0.492" height) and operating temperature range (-40°C to 85°C). UFW1E470MDD provides 25 V rating with 2000 Hrs @ 85°C lifetime and 115 mA ripple current. UFW1V470MDD provides 35 V rating with 2000 Hrs @ 85°C lifetime and 120 mA ripple current. Both offer enhanced voltage margins and doubled lifetime compared to the original 6.3 V, 1000 Hrs @ 85°C specification. Both are Obsolete products.

Q: What does ±20% tolerance mean for capacitance?

A: ±20% tolerance indicates the actual capacitance value may vary between 37.6 µF and 56.4 µF (47 µF ± 20%). All listed substitute parts maintain this identical tolerance specification, ensuring equivalent performance characteristics in circuit applications.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed maintain ROHS3 Compliant status, matching the environmental compliance requirement of the original RFS-6V470ME3#5.

Q: What is the significance of ripple current specifications?

A: Ripple current indicates the maximum AC current the capacitor can safely handle at specified frequency without exceeding temperature limits. The original part specifies 65 mA @ 120 Hz. Substitute parts with equal or higher ripple current ratings (such as UKT0J470MDD at 65 mA, UKT1A470MDD at 68 mA, or EEU-FC1C470 at 113.8 mA) are compatible. Parts with lower ripple current (such as 515D476M010JA6AE3 at 59 mA) require circuit analysis to confirm adequate margin.
