Engineering Selection Recommendations

UPW1H271MPD (Nichicon) is a direct manufacturer substitute from Nichicon with identical electrical and mechanical specifications. This part maintains the 5000-hour lifetime rating and is ROHS3 compliant, making it suitable for applications requiring compliance with modern environmental standards.

EEU-FC1H271 (Panasonic) is a cross-manufacturer equivalent with identical electrical and mechanical parameters. This part carries AEC-Q200 automotive qualification and ROHS3 compliance. The lifetime rating is 3000 hours at 105°C, which is lower than the main part. This part is currently Active and available for new designs.

For applications where the 5000-hour lifetime at 105°C is a critical requirement, UPW1H271MPD is the preferred selection. For automotive applications or where AEC-Q200 qualification is required, EEU-FC1H271 is appropriate, provided the 3000-hour lifetime meets application demands.

Frequently Asked Questions (FAQ)

Q: Can UPW1H271MPD be used as a direct replacement for UPW1H271MPH?

A: Yes. UPW1H271MPD matches all critical electrical and mechanical parameters: 270 µF capacitance, 50 V voltage rating, ±20% tolerance, 5000-hour lifetime at 105°C, identical package dimensions, lead spacing, and ripple current ratings. The primary difference is improved RoHS3 compliance.

Q: What is the key difference between UPW1H271MPD and EEU-FC1H271?

A: Both parts share identical capacitance, voltage, tolerance, package type, and ripple current specifications. The primary differences are: manufacturer (Nichicon vs. Panasonic), lifetime rating (5000 hours vs. 3000 hours at 105°C), and product certifications (EEU-FC1H271 includes AEC-Q200 automotive qualification).

Q: Is EEU-FC1H271 suitable for applications requiring 5000-hour lifetime at 105°C?

A: No. EEU-FC1H271 is rated for 3000 hours at 105°C. Applications with 5000-hour lifetime requirements must use UPW1H271MPD or equivalent parts with matching lifetime specifications.

Q: Are all substitute parts through-hole mounted with identical lead spacing?

A: Yes. All listed substitutes are through-hole mounted radial, can packages with 0.197" (5.00mm) lead spacing, ensuring mechanical compatibility with existing PCB layouts.

Q: What does "Not For New Designs" mean for UPW1H271MPD?

A: This designation indicates the part is available for existing production and maintenance but is not recommended for new product development. For new designs, EEU-FC1H271 (Active status) is the preferred selection if the 3000-hour lifetime is acceptable.
