Key Parameters

Substitute Part Grouping Explanation

Substitution of the EEE-FKA331XSL is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Parameters:

• Capacitance: 330 µF
• Voltage Rating: 10 V
• Tolerance: ±20%
• Operating Temperature Range: -55°C to 105°C
• Lifetime: 2000 Hrs @ 105°C
• Mounting Type: Surface Mount
• Package / Case: Radial, Can - SMD
• Physical Dimensions: 0.248" Dia (6.30 mm), Height 0.315" (8.00 mm)
• Surface Mount Land Size: 0.260" L x 0.260" W (6.60 mm x 6.60 mm)
• Polarization: Polar
• AEC-Q200 Compliance: Yes
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Performance Parameters (Variable):

• ESR @ 100 kHz: 340 mOhm (main part) to 160 mOhm (lower ESR alternatives)
• Ripple Current @ 120 Hz: 182 mA (main part) to 390 mA (higher ripple current alternatives)
• Ripple Current @ 100 kHz: 280 mA (main part) to 600 mA (higher ripple current alternatives)

Substitute parts are grouped into two categories based on ESR performance: standard ESR equivalents (340 mOhm) and low-ESR alternatives (160 mOhm). All substitutes maintain identical capacitance, voltage, tolerance, temperature range, lifetime, and physical form factor. Manufacturer differences and series variations are permitted provided all mandatory parameters remain equivalent.

Parameter Comparison

Engineering Selection Recommendations

Standard ESR Equivalents (340 mOhm @ 100 kHz):

EEE-FKA331XSP and EEE-FNA331XUL and EEE-FNA331XUP maintain identical electrical performance to the EEE-FKA331XSL with matching ESR, ripple current ratings, and lifetime specifications. EEE-FKA331XSP is designated "Not For New Designs" status, consistent with the main part. EEE-FNA331XUL and EEE-FNA331XUP are designated "Active" product status and represent current production alternatives within the standard ESR category. All three parts are Panasonic products with halogen-free or standard series designations and are suitable for direct substitution in applications where ESR performance is not a limiting factor.

Low-ESR Alternatives (160 mOhm @ 100 kHz):

EEE-FTA331XAL, EEE-FTA331XAP, and UCM1A331MCL1GS provide reduced ESR performance at 160 mOhm, resulting in higher ripple current handling capacity (390-600 mA @ 100 kHz versus 280 mA for the main part). These parts are designated "Active" product status. EEE-FTA331XAL and EEE-FTA331XAP are Panasonic FT series halogen-free components. UCM1A331MCL1GS is a Nichicon UCM series component with equivalent electrical specifications. Low-ESR alternatives are suitable for applications requiring enhanced thermal performance or higher ripple current dissipation while maintaining all other electrical and mechanical parameters.

Compliance and Certification:

All substitute parts maintain AEC-Q200 automotive qualification, ROHS3 compliance, and Moisture Sensitivity Level 1 (Unlimited) rating. The EEE-FKA331XSL and EEE-FKA331XSP are halogen-free within the FKS series. EEE-FNA331XUL, EEE-FNA331XUP, EEE-FTA331XAL, and EEE-FTA331XAP are halogen-free within their respective series. UCM1A331MCL1GS is subject to REACH regulations, whereas all Panasonic alternatives are REACH Unaffected. Selection between Panasonic and Nichicon alternatives depends on supply chain requirements and REACH compliance mandates for the end application.

Frequently Asked Questions (FAQ)

Q: Can EEE-FNA331XUL or EEE-FNA331XUP be used as direct replacements for EEE-FKA331XSL?

A: Yes. EEE-FNA331XUL and EEE-FNA331XUP are direct parametric equivalents with identical capacitance (330 µF), voltage rating (10 V), tolerance (±20%), ESR (340 mOhm @ 100 kHz), lifetime (2000 Hrs @ 105°C), operating temperature range (-55°C to 105°C), and physical dimensions. Both are designated "Active" product status, making them suitable for new designs. No circuit modifications are required.

Q: What is the difference between standard ESR and low-ESR substitute parts?

A: Standard ESR parts (EEE-FKA331XSP, EEE-FNA331XUL, EEE-FNA331XUP) have 340 mOhm ESR @ 100 kHz with ripple current ratings of 182 mA @ 120 Hz and 280 mA @ 100 kHz. Low-ESR parts (EEE-FTA331XAL, EEE-FTA331XAP, UCM1A331MCL1GS) have 160 mOhm ESR @ 100 kHz with ripple current ratings of 300-390 mA @ 120 Hz and 600 mA @ 100 kHz. Lower ESR reduces heat generation and improves thermal performance in high-ripple-current applications. Selection depends on circuit ripple current requirements.

Q: Are Panasonic and Nichicon parts interchangeable?

A: Panasonic EEE-FTA331XAL, EEE-FTA331XAP, EEE-FNA331XUL, and EEE-FNA331XUP are parametrically equivalent to Nichicon UCM1A331MCL1GS. All share identical capacitance, voltage, tolerance, temperature range, lifetime, and physical form factor. Nichicon UCM1A331MCL1GS is subject to REACH regulations, while Panasonic alternatives are REACH Unaffected. Selection between manufacturers depends on supply chain availability and regulatory requirements specific to the end application.

Q: Can low-ESR parts be used in applications designed for standard ESR parts?

A: Yes. Low-ESR parts (160 mOhm) are superior alternatives to standard ESR parts (340 mOhm) in all applications. Lower ESR provides reduced heat dissipation, improved voltage stability, and higher ripple current capacity. No circuit modifications are required. Low-ESR substitution is a performance upgrade that maintains backward compatibility.

Q: What is the significance of "Not For New Designs" status?

A: EEE-FKA331XSL and EEE-FKA331XSP are designated "Not For New Designs," indicating these parts are in mature or declining production phases. For new circuit designs, Panasonic recommends EEE-FNA331XUL, EEE-FNA331XUP, EEE-FTA331XAL, or EEE-FTA331XAP, all designated "Active" status. Active parts have assured long-term availability and ongoing manufacturing support.

Q: Are all substitute parts halogen-free?

A: EEE-FKA331XSL, EEE-FKA331XSP, EEE-FNA331XUL, EEE-FNA331XUP, EEE-FTA331XAL, and EEE-FTA331XAP are halogen-free. Nichicon UCM1A331MCL1GS halogen-free status is not specified in the provided parameters. Verify halogen-free compliance with the component supplier if this requirement is mandatory for the end application.

Q: Do all parts fit the same PCB footprint?

A: Yes. All substitute parts share identical physical dimensions (0.248" Dia / 6.30 mm), height (0.315" / 8.00 mm), and surface mount land size (0.260" L x 0.260" W / 6.60 mm x 6.60 mm). No PCB layout modifications are required for substitution.

Q: What is Moisture Sensitivity Level 1?

A: Moisture Sensitivity Level 1 (Unlimited) indicates the component has unlimited shelf life and requires no special moisture control during storage, handling, or assembly. No dry-pack storage or baking procedures are necessary prior to soldering.
