Substitute Part Grouping Explanation

Substitution for the UPW2A680MPH is determined by strict equivalence across the following parameters:

Capacitance: 68 µF (exact match required)
Voltage Rating: 100 V (exact match required)
Tolerance: ±20% (exact match required)
Polarization: Polar (exact match required)
Package Type: Radial, Can (exact match required)
Mounting Type: Through Hole (exact match required)
Lead Spacing: 0.197" (5.00mm) (exact match required)
Diameter: 0.394" (10.00mm) (exact match required)

Substitute parts are grouped into two categories:

Direct Manufacturer Substitute (Nichicon UPW Series): UPW2A680MPD maintains identical electrical and mechanical specifications with improved RoHS3 compliance status.

Similar Manufacturer Substitute (Panasonic FC Series): EEU-FC2A680L provides equivalent core electrical parameters with automotive-grade certification (AEC-Q200) and active product status, though with reduced lifetime rating and increased height dimension.

Engineering Selection Recommendations

UPW2A680MPD (Nichicon): This direct substitute maintains identical electrical performance and mechanical dimensions while offering improved regulatory compliance through ROHS3 certification. Suitable for applications where Nichicon UPW series continuity is required and lifetime requirements match the original specification of 5000 hours at 105°C.

EEU-FC2A680L (Panasonic): This substitute provides active product status with AEC-Q200 automotive-grade certification and ROHS3 compliance. The increased height dimension (0.984" vs. 0.787") requires PCB layout verification. The reduced lifetime rating of 3000 hours at 105°C and lower ripple current specification (295.8 mA vs. 318.5 mA) necessitate thermal and ripple current analysis for applications with demanding operational profiles. Lower impedance (210 mOhms vs. 300 mOhms) provides improved high-frequency performance.

Frequently Asked Questions (FAQ)

Q: Can UPW2A680MPD be used as a direct replacement for UPW2A680MPH?

A: Yes. UPW2A680MPD maintains identical capacitance, voltage rating, tolerance, temperature range, lifetime rating, ripple current specification, impedance, lead spacing, and diameter. The primary difference is improved RoHS3 compliance status. No circuit modifications are required.

Q: What are the limitations of using EEU-FC2A680L as a substitute?

A: EEU-FC2A680L introduces three design considerations: (1) increased height of 0.984" (25.00mm) versus 0.787" (20.00mm) requires PCB layout clearance verification; (2) reduced lifetime rating of 3000 hours at 105°C versus 5000 hours may impact long-term reliability in high-temperature applications; (3) lower ripple current specification of 295.8 mA at 120 Hz versus 318.5 mA requires thermal analysis for high-ripple applications.

Q: Are all substitute parts through-hole mounted?

A: Yes. All listed substitutes maintain through-hole mounting with identical lead spacing of 0.197" (5.00mm) and diameter of 0.394" (10.00mm), ensuring PCB footprint compatibility.

Q: What compliance certifications apply to each substitute?

A: UPW2A680MPH is RoHS non-compliant. UPW2A680MPD achieves ROHS3 compliance. EEU-FC2A680L achieves ROHS3 compliance and carries AEC-Q200 automotive-grade certification, suitable for automotive applications.

Q: Which substitute is recommended for new designs?

A: EEU-FC2A680L carries active product status and is suitable for new designs. UPW2A680MPD is classified as "Not For New Designs." Both substitutes require verification of height clearance and thermal/ripple current requirements specific to the application.
