2SW330M Equivalent & Substitute Parts

Part Overview

The 2SW330M is a 330 µF, 2 V aluminum polymer capacitor manufactured by Rubycon in the 2917 (7343 Metric) surface mount package. This component is designed for general-purpose applications requiring low equivalent series resistance and stable performance across extended temperature ranges. The part is currently obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 2SW330M is based on the following critical parameters that must remain constant:

• Capacitance value: 330 µF
• Voltage rating: 2 V
• Package type: 2917 (7343 Metric)
• Mounting configuration: Surface Mount
• Operating temperature range: -55°C to 105°C
• Lifetime specification: 2000 Hrs @ 105°C
• Tolerance: ±20%

The EEF-SX0D331XE from Panasonic Electronic Components meets all these requirements and is classified as an active product with current availability.

Parameter Comparison

Engineering Selection Recommendations

The EEF-SX0D331XE is the direct equivalent for the obsolete 2SW330M. Both components share identical electrical specifications for capacitance, voltage rating, tolerance, and operating temperature range. The Panasonic substitute offers improved performance characteristics with lower ESR (6 mOhm versus 9 mOhm) and higher ripple current capability (7.5 A versus 4.6 A at 100 kHz), making it suitable for applications with higher current demands.

The EEF-SX0D331XE is ROHS3 compliant and REACH unaffected, matching the regulatory status of the original part. As an active product with current manufacturing status, the Panasonic component ensures long-term supply availability. The reduced height (2.00mm versus 2.90mm) provides additional design flexibility for space-constrained applications while maintaining identical footprint dimensions.

Frequently Asked Questions (FAQ)

Q: Can the EEF-SX0D331XE be used as a direct replacement for the 2SW330M?

A: Yes. Both components share identical capacitance (330 µF), voltage rating (2 V), package type (2917 Metric), and operating temperature range (-55°C to 105°C). The Panasonic part is electrically and mechanically compatible for direct substitution.

Q: What are the differences between these two parts?

A: The primary differences are ESR and ripple current performance. The EEF-SX0D331XE has lower ESR (6 mOhm versus 9 mOhm) and higher ripple current capability (7.5 A versus 4.6 A at 100 kHz). The Panasonic part also has a reduced seated height (2.00mm versus 2.90mm). These differences represent performance improvements over the original design.

Q: Are there any height clearance concerns with the substitute part?

A: No. The EEF-SX0D331XE has a lower maximum seated height (2.00mm) compared to the 2SW330M (2.90mm), which provides additional clearance in space-constrained designs. The footprint dimensions remain identical.

Q: What is the packaging format for the substitute part?

A: The EEF-SX0D331XE is supplied in Tape & Reel (TR) format, which is standard for high-volume surface mount assembly operations.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the 2SW330M and EEF-SX0D331XE are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
