Substitute Part Grouping Explanation

Substitution eligibility for the RSA0G331MCN1GS is determined by strict equivalence across the following parameters:

• Capacitance value: 330 µF (exact match required)
• Voltage rating: 4 V (exact match required)
• Tolerance: ±20% (exact match required)
• ESR: 14 mOhm (exact match required)
• Lifetime rating: 2000 Hrs @ 105°C (exact match required)
• Operating temperature range: -55°C to 105°C (exact match required)
• Case dimensions: 0.248" Dia (6.30 mm) and 0.236" height (6.00 mm) (exact match required)
• Mounting type: Surface Mount (exact match required)
• Package type: Radial, Can - SMD (exact match required)
• Regulatory compliance: ROHS3 and REACH status (exact match required)

The KEMET A765EB337M0GLAE014 meets all substitution criteria and is classified as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the RSA0G331MCN1GS and A765EB337M0GLAE014 are active production components with full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on availability, lead time, and procurement cost. The KEMET substitute maintains electrical equivalence across all critical parameters including capacitance, voltage rating, ESR, and thermal lifetime. Both components are suitable for general purpose applications within the specified operating temperature range. Land size dimensions differ slightly (6.50 mm vs 6.60 mm), which may require PCB layout verification for designs with tight spacing constraints.

Frequently Asked Questions (FAQ)

Q: Can the A765EB337M0GLAE014 be used as a direct replacement for the RSA0G331MCN1GS?

A: Yes. Both parts share identical electrical specifications (330 µF, 4 V, ±20%, 14 mOhm ESR, 2000 Hrs @ 105°C) and mechanical dimensions (0.248" diameter, 0.236" height). Both are ROHS3 compliant and rated for -55°C to 105°C operation. PCB land size differs by 0.010" (0.26 mm), which is within typical manufacturing tolerances for surface mount assembly.

Q: Are there differences in ripple current ratings between these parts?

A: The ripple current at 120 Hz differs between manufacturers (316 mA for Nichicon vs 158 mA for KEMET). The ripple current at 100 kHz is identical at 3.16 A. Applications requiring specific low-frequency ripple current performance should verify the KEMET specification against circuit requirements.

Q: What is the moisture sensitivity level of the KEMET substitute?

A: The A765EB337M0GLAE014 is rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Are both parts suitable for the same applications?

A: Both parts are rated for general purpose applications and maintain equivalent thermal and electrical performance across the specified operating temperature range. Component selection should be based on availability and procurement requirements.
