Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EEE-FC1A151P is determined by strict equivalence across the following parameters:

• Capacitance value: 150 µF (exact match required)
• Voltage rating: 10 V (exact match required)
• Tolerance: ±20% (exact match required)
• Package type: Radial, Can - SMD (exact match required)
• Case diameter: 0.315" (8.00 mm) (exact match required)
• Land size: 0.327" L x 0.327" W (8.30 x 8.30 mm) (exact match required)
• Mounting type: Surface Mount (exact match required)
• Polarization: Polar (exact match required)
• AEC-Q200 automotive rating (required for automotive applications)

All three substitute parts meet these core electrical and mechanical compatibility criteria. Differences in operating temperature range, lifetime temperature rating, product status, and RoHS revision level do not affect functional substitution but may influence selection based on application requirements and supply chain considerations.

Parameter Comparison

Engineering Selection Recommendations

EEE-FC1A151AP (Panasonic): This part maintains identical electrical and mechanical specifications to the main part and shares the same Panasonic FC series base platform. However, it carries "Not For New Designs" status, making it unsuitable for new product development. Selection is limited to legacy system maintenance or direct replacement scenarios where supply continuity is the primary concern.

EDT157M010S9LAA (KEMET): This substitute offers an extended operating temperature range to 125°C and improved lifetime rating at elevated temperature (1000 Hrs @ 125°C). It carries Active product status and ROHS3 compliance, supporting long-term design viability. The case height is 0.256" (6.50 mm) compared to 0.244" (6.20 mm) for the main part, requiring verification of PCB clearance in height-constrained applications. Ripple current ratings are lower than the main part, necessitating thermal analysis for high-ripple-current circuits.

UWG1A151MCL1GS (Nichicon): This substitute provides the widest operating temperature range (-55°C to 105°C) and carries Active product status with ROHS3 compliance. Electrical specifications match the main part closely, including impedance and high-frequency ripple current. The extended lower temperature limit supports applications in extreme cold environments. This option offers the strongest long-term supply security and design flexibility.

Frequently Asked Questions (FAQ)

Q: Can EEE-FC1A151AP be used as a direct replacement for EEE-FC1A151P?

A: Yes, EEE-FC1A151AP is electrically and mechanically equivalent. However, both parts carry "Not For New Designs" status. For new product development, EDT157M010S9LAA or UWG1A151MCL1GS are preferred.

Q: What is the significance of the case height difference in EDT157M010S9LAA?

A: EDT157M010S9LAA has a maximum seated height of 0.256" (6.50 mm) versus 0.244" (6.20 mm) for the main part. This 0.012" (0.30 mm) difference must be verified against PCB layout constraints, particularly in applications with limited vertical clearance or stacked component arrangements.

Q: Are all substitute parts AEC-Q200 rated?

A: Yes. All three substitute parts carry AEC-Q200 automotive qualification, maintaining compliance for automotive applications.

Q: Which substitute offers the best long-term availability?

A: UWG1A151MCL1GS and EDT157M010S9LAA both carry Active product status, indicating ongoing manufacturing and supply commitment. EEE-FC1A151AP is "Not For New Designs," signaling potential supply discontinuation.

Q: Do ripple current differences affect substitution?

A: Ripple current ratings vary across substitutes. EDT157M010S9LAA shows lower ripple current capability (75 mA @ 120 Hz, 107.143 mA @ 100 kHz) compared to the main part (172.5 mA @ 120 Hz, 230 mA @ 100 kHz). Circuit thermal analysis is required if the application operates near ripple current limits.

Q: What is the difference between RoHS and ROHS3 compliance?

A: Both designations indicate lead-free compliance. ROHS3 represents the current revision of the RoHS directive. All parts meet lead-free requirements; ROHS3 designation indicates alignment with current regulatory standards.

Q: Can UWG1A151MCL1GS be used in high-temperature applications?

A: UWG1A151MCL1GS operates to 105°C maximum, matching the main part. EDT157M010S9LAA extends to 125°C and is rated for 1000 hours at 125°C, making it the better choice for sustained high-temperature operation.
