Key Parameters

Substitute Part Grouping Explanation

Substitution of the 337SML025M is permissible with the Panasonic EEE-FK1E331P based on the following alignment of critical parameters:

Electrical Equivalence:

• Capacitance: Both parts rated at 330 µF
• Voltage Rating: Both parts rated at 25 V
• Tolerance: Both parts specified at ±20%
• Polarization: Both parts are polar aluminum electrolytic capacitors

Mechanical Compatibility:

• Package Type: Both are Radial, Can - SMD configurations
• Mounting Type: Both are surface mount
• Physical Diameter: Both measure 0.315" (8.00 mm)
• Physical Height: 337SML025M at 0.417" (10.60 mm) maximum; EEE-FK1E331P at 0.413" (10.50 mm) maximum—within acceptable tolerance for PCB assembly
• Surface Mount Land Size: Both require 0.327" L x 0.327" W (8.30 mm x 8.30 mm) footprint

Compliance Alignment:

• RoHS3 Compliant: Both parts meet RoHS3 requirements
• Moisture Sensitivity Level: Both rated MSL 1 (Unlimited)
• REACH Status: Both are REACH Unaffected
• ECCN Classification: Both classified as EAR99
• HTSUS Code: Both classified under 8532.22.0020

The substitute part is qualified for direct replacement in applications where the specified electrical and mechanical parameters are the primary selection criteria.

Parameter Comparison

Engineering Selection Recommendations

Both the 337SML025M and EEE-FK1E331P are active production parts with RoHS3 compliance and MSL 1 ratings, making them suitable for direct substitution in applications requiring 330 µF, 25 V aluminum electrolytic capacitors in surface mount radial can packages.

The EEE-FK1E331P offers an extended operating temperature range (-55°C to 105°C versus -40°C to 85°C) and higher ripple current ratings at both 120 Hz and 100 kHz. The Panasonic part also carries AEC-Q200 automotive qualification, which may be relevant for applications requiring automotive-grade components.

Physical dimensions are compatible, with the EEE-FK1E331P height (0.413" maximum) being 0.004" shorter than the 337SML025M (0.417" maximum), presenting no clearance concerns for standard PCB assembly.

Both parts are REACH Unaffected and classified as EAR99 for export control purposes.

Frequently Asked Questions (FAQ)

Q: Can the EEE-FK1E331P directly replace the 337SML025M on a PCB?

A: Yes. Both parts share identical capacitance (330 µF), voltage rating (25 V), tolerance (±20%), physical diameter (0.315" / 8.00 mm), and surface mount land size (0.327" x 0.327" / 8.30 mm x 8.30 mm). The EEE-FK1E331P height is 0.004" shorter, which does not create assembly or clearance issues.

Q: What are the key electrical differences between these parts?

A: The primary electrical differences are ripple current ratings and operating temperature range. The EEE-FK1E331P supports higher ripple currents (450 mA @ 120 Hz and 600 mA @ 100 kHz versus 270 mA and 405 mA respectively) and operates across a wider temperature range (-55°C to 105°C versus -40°C to 85°C). The 337SML025M specifies ESR at 700 mOhm @ 120 Hz; the EEE-FK1E331P specifies impedance at 160 mOhms.

Q: Are both parts compliant with environmental and regulatory standards?

A: Yes. Both the 337SML025M and EEE-FK1E331P are RoHS3 compliant, REACH Unaffected, and classified as EAR99 for export control. Both carry MSL 1 (Unlimited) moisture sensitivity ratings.

Q: Does the EEE-FK1E331P have any additional certifications?

A: The EEE-FK1E331P carries AEC-Q200 automotive qualification. This certification is relevant for applications requiring automotive-grade component reliability but is not required for general purpose applications.

Q: What packaging formats are available?

A: The 337SML025M packaging format is not specified in the provided data. The EEE-FK1E331P is supplied in Tape & Reel (TR) format, which is standard for high-volume surface mount assembly.

Q: Can these parts be used interchangeably in all applications?

A: Substitution is valid for applications where the specified electrical parameters (330 µF, 25 V, ±20% tolerance) and mechanical compatibility (surface mount radial can, 8.00 mm diameter, 8.30 mm x 8.30 mm land size) are the primary selection criteria. Applications with specific ripple current, temperature range, or automotive qualification requirements should evaluate the performance differences noted in the parameter comparison table.
