Engineering Selection Recommendations

Direct Manufacturer Substitute: EEE-FPV391UAP

The EEE-FPV391UAP is a direct substitute manufactured by Panasonic Electronic Components within the same FP series. This part maintains identical electrical specifications and compliance certifications. The seated height is 10.20 mm compared to 10.50 mm on the primary part, representing a 0.30 mm reduction. Both parts share the same surface mount land size and mounting footprint. This substitute is suitable for applications where the reduced height provides design flexibility without compromising electrical performance or automotive qualification.

Parametric Equivalent Substitute: 35TKV390M10X10.5

The 35TKV390M10X10.5 is a parametric equivalent manufactured by Rubycon in the TKV series. This part matches all critical electrical parameters including capacitance, voltage rating, ESR, lifetime, and high-frequency ripple current. The seated height is 10.50 mm, identical to the primary part. Low-frequency ripple current is specified at 510 mA @ 120 Hz compared to 552.5 mA on the Panasonic parts, representing a 7.7% reduction. All parts carry AEC-Q200 automotive qualification and RoHS3 compliance. The Rubycon substitute is suitable for applications where cross-manufacturer sourcing is required.

Frequently Asked Questions (FAQ)

Q: Can EEE-FPV391UAP be used as a direct replacement for EEE-FPV391UAL?

A: Yes. Both parts are manufactured by Panasonic, share identical electrical specifications, and carry the same AEC-Q200 and RoHS3 certifications. The primary difference is seated height: 10.20 mm versus 10.50 mm. Both conform to the same 10.30 mm × 10.30 mm surface mount land size, making them mechanically compatible on the same PCB footprint.

Q: What is the difference between the Panasonic and Rubycon substitutes?

A: The Rubycon 35TKV390M10X10.5 is a cross-manufacturer substitute that matches all critical electrical parameters. The low-frequency ripple current specification differs: Rubycon specifies 510 mA @ 120 Hz versus 552.5 mA for Panasonic parts. High-frequency ripple current (850 mA @ 100 kHz) is identical across all three parts. All three parts meet AEC-Q200 automotive qualification and RoHS3 compliance.

Q: Are all three parts suitable for automotive applications?

A: Yes. All three parts carry AEC-Q200 qualification and are rated for automotive applications. Operating temperature range, lifetime at elevated temperature, and compliance certifications are identical across all substitutes.

Q: Does the height difference between EEE-FPV391UAL and EEE-FPV391UAP affect PCB assembly?

A: The height difference is 0.30 mm (10.50 mm versus 10.20 mm). Both parts use the same surface mount land size (10.30 mm × 10.30 mm) and mounting type. The reduced height of the EEE-FPV391UAP may provide clearance advantages in space-constrained designs but does not affect electrical compatibility or assembly process.

Q: Can these parts be used interchangeably in the same design?

A: Yes, within the constraints of physical clearance. All three parts share identical electrical specifications, ESR values, ripple current ratings at 100 kHz, and compliance certifications. The only variables are seated height and low-frequency ripple current on the Rubycon part. PCB layout and component placement should be verified to accommodate the height variations.

Q: What is the significance of the ±20% tolerance specification?

A: The ±20% tolerance indicates that actual capacitance values will fall within the range of 312 µF to 468 µF. This tolerance applies equally to all three substitute parts and is typical for aluminum electrolytic capacitors in this voltage and capacitance range.

Q: Are moisture sensitivity considerations the same for all three parts?

A: Yes. All three parts carry MSL Rating 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard handling and storage practices apply without special moisture control requirements.
