Engineering Selection Recommendations

MPL337M0EG19TRX0 (Manyue) is a parametric equivalent to the 2.5SWZ330M-ND. This part matches all critical electrical specifications: 330 µF capacitance, 2.5 V voltage rating, 9 mOhm ESR, and identical package dimensions. The Manyue part carries Active product status and ROHS3 compliance, making it suitable for direct replacement in applications currently using the Rubycon component.

EEF-CX0J101R (Panasonic) is a functional substitute with significant parameter differences. This part has a lower capacitance value (100 µF versus 330 µF) and a higher voltage rating (6.3 V versus 2.5 V). The higher ESR (15 mOhm versus 9 mOhm) may affect circuit performance in applications sensitive to impedance characteristics. This part is suitable only when the application can tolerate reduced capacitance and the higher voltage rating does not create design conflicts. Panasonic's Active product status and ROHS3 compliance support long-term availability.

Frequently Asked Questions (FAQ)

Q: Can MPL337M0EG19TRX0 be used as a direct replacement for 2.5SWZ330M-ND?

A: Yes. The MPL337M0EG19TRX0 matches all critical parameters: 330 µF capacitance, 2.5 V voltage rating, 9 mOhm ESR, 2000 Hrs @ 105°C lifetime, and 2917 (7343 Metric) package. No circuit modifications are required.

Q: What are the limitations of using EEF-CX0J101R as a substitute?

A: The EEF-CX0J101R has 100 µF capacitance instead of 330 µF, representing a 70% reduction in capacitive value. The ESR is 15 mOhm instead of 9 mOhm. Applications requiring the full 330 µF capacitance or sensitive to ESR performance will not function correctly with this substitute.

Q: Are all substitute parts in the same package?

A: Yes. Both substitute parts use the 2917 (7343 Metric) surface mount package with identical physical dimensions (7.30 mm x 4.30 mm) and height (1.90 mm maximum seated height). PCB layout compatibility is maintained.

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

A: This designation indicates that Rubycon has discontinued or is phasing out the 2.5SWZ330M-ND from its active product line. For new designs, the parametric equivalent MPL337M0EG19TRX0 or other active alternatives should be selected. For legacy system support and repairs, the original part or its equivalent remains available through inventory channels.

Q: Do all parts meet the same compliance standards?

A: Yes. The 2.5SWZ330M-ND, MPL337M0EG19TRX0, and EEF-CX0J101R are all ROHS3 compliant and REACH unaffected. MSL ratings are consistent at Level 3 (168 Hours) for parts where specified.
