Engineering Selection Recommendations

UPW1V561MPD (Nichicon): This direct Nichicon alternative maintains identical electrical and mechanical specifications to the UPW1V561MPH while offering ROHS3 compliance and improved product status classification. Suitable for applications requiring same-manufacturer continuity with enhanced regulatory compliance. Not recommended for new designs due to product status designation.

EEU-FC1V561 (Panasonic): This cross-manufacturer substitute provides active product status and AEC-Q200 automotive qualification. However, the 3000-hour lifetime at 105°C falls below the 5000-hour specification of the original part. Selection requires verification that reduced lifetime meets application requirements. ROHS3 compliant. Recommended only when automotive qualification is a primary requirement and reduced lifetime is acceptable.

EEU-FC1V561S (Panasonic): This Panasonic alternative matches the 5000-hour lifetime specification and provides active product status with ROHS3 compliance and AEC-Q200 automotive qualification. Physical dimensions differ slightly (0.492" diameter, 0.787" height versus 0.394" diameter, 0.984" height), requiring verification of available circuit board space. Enhanced ripple current capability (1.241 A @ 120 Hz, 1.655 A @ 100 kHz) and lower impedance (38 mOhms) provide improved performance margins. Recommended as the primary substitute for new applications and redesigns.

Frequently Asked Questions (FAQ)

Q: Can EEU-FC1V561S be used as a direct replacement for UPW1V561MPH on existing circuit boards?

A: Physical dimensions differ. The EEU-FC1V561S has a larger diameter (0.492" versus 0.394") and reduced height (0.787" versus 0.984"). Lead spacing remains identical at 0.197" (5.00 mm), ensuring electrical compatibility. Circuit board layout must be verified to confirm adequate clearance around the component footprint before substitution.

Q: What is the significance of the 3000-hour versus 5000-hour lifetime rating?

A: Lifetime rating indicates the expected operational duration at maximum rated temperature (105°C) before capacitance degradation reaches 80% of initial value. The EEU-FC1V561 offers 3000 hours, while UPW1V561MPH and EEU-FC1V561S offer 5000 hours. Applications requiring extended service life or operating continuously at elevated temperatures should specify the 5000-hour rated component.

Q: Are Panasonic EEU-FC series capacitors suitable for automotive applications?

A: Yes. Both EEU-FC1V561 and EEU-FC1V561S carry AEC-Q200 automotive qualification and are designated for automotive applications. The original Nichicon UPW1V561MPH is classified for general purpose use without automotive certification.

Q: What does RoHS3 compliance mean for component selection?

A: ROHS3 compliance indicates the component meets Restriction of Hazardous Substances Directive requirements, restricting lead, cadmium, mercury, and other hazardous materials. The original UPW1V561MPH is RoHS non-compliant. All listed substitutes are ROHS3 compliant, meeting current regulatory requirements for new designs and manufacturing in regulated markets.

Q: Can the UPW1V561MPD be used in new product designs?

A: The UPW1V561MPD carries a "Not For New Designs" product status designation. While electrically and mechanically compatible, this classification indicates Nichicon does not recommend this part for new development. For new designs, EEU-FC1V561S is the preferred substitute due to active product status and full compliance certifications.

Q: How do impedance differences affect circuit performance?

A: Lower impedance (38 mOhms in EEU-FC1V561S versus 45 mOhms in UPW1V561MPH) reduces voltage ripple and improves high-frequency filtering performance. This provides improved noise suppression and voltage stability, particularly beneficial in power supply and signal conditioning applications. The difference is generally favorable for circuit performance.
