Substitute Part Grouping Explanation

Substitution of the 2SEPC330MW is determined by strict equivalence across the following electrical and mechanical parameters:

• Capacitance value: 330 µF (exact match required)
• Voltage rating: 2.5 V (exact match required)
• Tolerance: ±20% (exact match required)
• Type: Aluminum Polymer (exact match required)
• ESR: 7 mOhm (exact match required)
• Lifetime: 5000 Hrs @ 105°C (exact match required)
• Operating temperature range: -55°C to 105°C (exact match required)
• Mounting type: Through Hole (exact match required)
• Package: Radial, Can (exact match required)
• Lead spacing: 0.098" (2.50 mm) (exact match required)
• Physical dimensions: 0.248" Dia (6.30 mm) (exact match required)

The Nichicon RS80E331MDNASQ and RS80E331MDNASQJT meet all electrical and mechanical substitution criteria. Both parts are manufactured by Nichicon, carry active product status, and maintain full compliance with RoHS3 and REACH standards.

Parameter Comparison

Engineering Selection Recommendations

Both Nichicon substitute parts RS80E331MDNASQ and RS80E331MDNASQJT provide direct electrical and mechanical equivalence to the obsolete 2SEPC330MW. Selection between the two Nichicon options is determined by packaging requirements:

RS80E331MDNASQ is supplied in bag packaging and is suitable for applications where standard component handling and storage procedures are employed.

RS80E331MDNASQJT is supplied in tape and box packaging and is appropriate for automated assembly processes or applications requiring controlled component presentation.

Both parts carry active product status, ensuring long-term availability and supply chain stability. Both maintain full RoHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component manufacturing and distribution.

Frequently Asked Questions (FAQ)

Q: Can RS80E331MDNASQ and RS80E331MDNASQJT be used interchangeably with 2SEPC330MW?

A: Yes. Both Nichicon parts meet all electrical and mechanical specifications of the 2SEPC330MW. The difference between them is packaging format only: bag versus tape and box. Electrical performance and physical dimensions are identical.

Q: What is the difference between RS80E331MDNASQ and RS80E331MDNASQJT?

A: The primary difference is packaging. RS80E331MDNASQ arrives in bag packaging, while RS80E331MDNASQJT arrives in tape and box packaging. The seated height of RS80E331MDNASQJT is 0.315" (8.00 mm) compared to 0.354" (9.00 mm) for RS80E331MDNASQ. Both parts are electrically identical and functionally equivalent.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both RS80E331MDNASQ and RS80E331MDNASQJT are ROHS3 compliant and REACH unaffected, meeting current regulatory standards for electronic components.

Q: What is the ripple current rating difference between the original and substitute parts?

A: At 120 Hz low frequency, the original 2SEPC330MW is rated for 280 mA, while both Nichicon substitutes are rated for 560 mA. At 100 kHz high frequency, all three parts are rated identically at 5.6 A. The higher low-frequency ripple current rating of the Nichicon parts provides additional design margin.

Q: Are there inventory considerations for these substitute parts?

A: RS80E331MDNASQ has 804 pieces in stock, and RS80E331MDNASQJT has 1023 pieces in stock, both available as new original components. The original 2SEPC330MW is obsolete with 941 pieces remaining in inventory.
