Operating Temperature Range: -55°C to 105°C
Lifetime: 2000 Hrs @ 105°C
Polarization: Polar

Core Mechanical Parameters (Must Match):

Mounting Type: Surface Mount
Package / Case: Radial, Can - SMD
Size / Dimension: 0.248" Dia (6.30mm)
Surface Mount Land Size: 0.260" L x 0.260" W (6.60mm x 6.60mm)

Engineering Selection Recommendations

All identified substitute parts are active products with AEC-Q200 automotive qualification and RoHS3 compliance, meeting the regulatory and quality requirements of the original EEE-FP1E330AL.

Direct Panasonic Substitutes:

EEE-FP1E330AP: Same FP series as the main part with identical electrical specifications. Height difference of 0.012" (0.30mm) is within typical PCB assembly tolerances. Higher inventory availability (2598 pcs) supports supply continuity.
EEE-FK1E330P: Panasonic FK series with equivalent electrical and mechanical parameters. Significantly higher inventory (29035 pcs) provides extended supply assurance. Suitable for applications where manufacturer consistency is prioritized.

Rubycon Substitutes:

25SGV33M6.3X6.1: SGV series with matching core specifications. Inventory of 2350 pcs supports standard procurement cycles.
25TZV33M6.3X6.1: TZV series with matching core specifications and ripple current performance at 100 kHz (250 mA) comparable to the main part (300 mA). Inventory of 3651 pcs available.

Nichicon Substitutes:

UCD1E330MCL1GS: UCD series with matching specifications. Highest inventory availability (5886 pcs) among all substitutes. REACH Affected status requires verification for specific supply chain requirements.
UUD1E330MCL1GS: UUD series with matching specifications. Impedance of 440 mOhms represents a secondary parameter variation. Inventory of 2992 pcs available. REACH Affected status requires verification for specific supply chain requirements.

Selection among these substitutes depends on manufacturer preference, supply chain strategy, and compliance documentation requirements specific to the end application.

Frequently Asked Questions (FAQ)

Q: Can EEE-FP1E330AP be used as a direct replacement for EEE-FP1E330AL?

A: Yes. Both parts are Panasonic FP series with identical capacitance (33 µF), voltage rating (25 V), tolerance (±20%), operating temperature range (-55°C to 105°C), and lifetime (2000 Hrs @ 105°C). The seated height difference of 0.012" (0.30mm) is within standard PCB assembly tolerances and does not affect electrical performance or mechanical fit on standard 0.260" x 0.260" land patterns.

Q: What is the difference between Panasonic FP and FK series substitutes?

A: Both FP and FK series meet the core electrical and mechanical requirements for substitution. The FK series (EEE-FK1E330P) has significantly higher inventory availability. Selection between series depends on design documentation requirements and manufacturer qualification preferences.

Q: Are Rubycon and Nichicon parts fully compatible with the Panasonic EEE-FP1E330AL?

A: Yes. All Rubycon (25SGV33M6.3X6.1, 25TZV33M6.3X6.1) and Nichicon (UCD1E330MCL1GS, UUD1E330MCL1GS) parts meet the core electrical specifications (33 µF, 25 V, ±20%, -55°C to 105°C, 2000 Hrs @ 105°C), mechanical dimensions (0.248" Dia, 0.240" height, 0.260" x 0.260" land size), and automotive compliance (AEC-Q200, RoHS3). These parts are suitable for applications where multi-source qualification is acceptable.

Q: What is the significance of the ESR and ripple current differences among substitutes?

A: ESR and ripple current are secondary performance parameters. The main part specifies 260 mOhm ESR @ 100 kHz and 300 mA ripple current @ 100 kHz. Substitute parts with different ESR or ripple current values remain electrically compatible for the core 33 µF, 25 V function. Applications with specific ESR or ripple current requirements should reference the detailed specifications of each substitute part.

Q: Does the height difference between EEE-FP1E330AL (0.240") and EEE-FP1E330AP (0.228") affect PCB assembly?

A: No. The 0.012" (0.30mm) height difference is within standard PCB assembly tolerances and does not affect component placement, solder reflow profiles, or mechanical clearance on typical automotive circuit boards. Both parts use identical 0.260" x 0.260" land patterns.

Q: Are there any compliance considerations when switching between Panasonic and other manufacturers?

A: All identified substitutes carry AEC-Q200 automotive qualification and RoHS3 compliance. Nichicon parts (UCD1E330MCL1GS, UUD1E330MCL1GS) are marked as REACH Affected, while Panasonic and Rubycon parts are REACH Unaffected. Verify REACH compliance requirements with your supply chain or regulatory documentation before final part selection.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes. All substitute parts share identical mechanical footprints (0.260" x 0.260" land size, 0.248" diameter, and 0.240" maximum height with minor exceptions noted). PCB designs do not require modification to accommodate any of these substitutes.
