Substitute Part Grouping Explanation

Substitution eligibility for the UPW1C122MPH is determined by strict equivalence across the following parameters: capacitance value (1200 µF), voltage rating (16 V), tolerance (±20%), polarization (polar), package type (radial can), mounting method (through hole), and physical dimensions (lead spacing, diameter, height). Substitute parts must maintain compatibility with printed circuit board layouts and electrical performance requirements.

The substitute parts are grouped into two categories:

Direct Manufacturer Substitutes: Parts from Nichicon that share identical electrical specifications and physical dimensions with the main part.

Cross-Manufacturer Equivalents: Parts from alternative manufacturers (Panasonic) that meet the same electrical and mechanical requirements, with variations noted in lifetime ratings and ripple current specifications.

Engineering Selection Recommendations

UPW1C122MPD (Nichicon): This direct Nichicon substitute maintains identical electrical and mechanical specifications to the UPW1C122MPH, including 5000-hour lifetime at 105°C and matching physical dimensions. The part is classified as "Not For New Designs" but remains suitable for legacy system support and replacement applications. RoHS3 compliance provides environmental regulatory advantage over the original obsolete part.

EEU-FC1C122 (Panasonic): This Panasonic equivalent matches all critical electrical parameters and physical dimensions with the main part. The lifetime rating is reduced to 3000 hours at 105°C, representing a 40% reduction in rated operational life. This part carries AEC-Q200 automotive qualification and ROHS3 compliance. Selection of this part requires confirmation that the reduced lifetime meets system reliability requirements.

EEU-FC1C122S (Panasonic): This Panasonic part maintains the 5000-hour lifetime specification matching the original UPW1C122MPH. However, physical dimensions differ significantly: lead spacing increases from 5.00mm to 7.50mm, diameter increases from 10.00mm to 16.00mm, and height decreases from 25.00mm to 15.00mm. These dimensional changes require PCB layout verification before implementation. The part carries AEC-Q200 automotive qualification and ROHS3 compliance. Ripple current ratings are higher than the original specification.

Frequently Asked Questions (FAQ)

Q: Can EEU-FC1C122S be used as a direct replacement for UPW1C122MPH?

A: EEU-FC1C122S is electrically equivalent but not mechanically interchangeable. The lead spacing, diameter, and height differ from the original part. PCB layout modifications are required for implementation.

Q: What is the primary difference between EEU-FC1C122 and EEU-FC1C122S?

A: EEU-FC1C122 has a rated lifetime of 3000 hours at 105°C, while EEU-FC1C122S has 5000 hours. EEU-FC1C122S also has different physical dimensions and higher ripple current ratings.

Q: Is UPW1C122MPD suitable for new designs?

A: UPW1C122MPD is classified as "Not For New Designs." For new designs, Panasonic EEU-FC1C122 or EEU-FC1C122S are preferred as active products with full manufacturer support.

Q: What compliance advantages do the substitute parts offer?

A: All substitute parts are ROHS3 compliant, whereas the original UPW1C122MPH is RoHS non-compliant. This provides regulatory compliance for systems subject to environmental directives.

Q: Are the Panasonic parts automotive-qualified?

A: Yes, both EEU-FC1C122 and EEU-FC1C122S carry AEC-Q200 automotive qualification, suitable for automotive applications requiring this certification.

Q: How do ripple current ratings affect part selection?

A: Ripple current specifications must not be exceeded in the application circuit. EEU-FC1C122S provides higher ripple current capacity (1.69 A @ 100 kHz) compared to the original part (1.44 A @ 100 kHz), offering design margin in high-frequency applications.
