SK330M350ST Equivalent & Substitute Parts Reference

Part Overview

The SK330M350ST is a 33 µF aluminum electrolytic capacitor rated at 350 V with radial through-hole mounting. Manufactured by Cornell Dubilier Electronics (CDE), this component is active in production and designed for general-purpose applications. Identifying equivalent substitute parts is necessary when the primary part is unavailable due to supply constraints, when inventory levels require alternative sourcing, or when design requirements permit component interchange based on equivalent electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute part qualification for the SK330M350ST is based on the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Capacitance: 33 µF (matching value)
• Tolerance: ±20% (matching specification)
• Voltage Rating: 350 V (minimum required rated voltage)
• Polarization: Polar (required for this application)

Mechanical Compatibility Criteria:

• Mounting Type: Through Hole (consistent with PCB design)
• Package / Case: Radial, Can (physical form factor)
• Lead Spacing: 0.197" (5.00 mm) (PCB footprint requirement)

Compliance and Quality Criteria:

• RoHS3 Compliance (environmental regulation conformance)
• Product Status: Active (production availability)

The EEU-EE2V330 from Panasonic Electronic Components meets all critical electrical and mechanical substitution parameters while offering enhanced performance characteristics in lifetime rating and operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

The EEU-EE2V330 qualifies as a direct electrical and mechanical substitute for the SK330M350ST. Both components are active production parts maintaining ROHS3 compliance and REACH unaffected status. The Panasonic component offers equivalent core specifications while providing an extended operational temperature range (-25°C ~ 105°C versus -25°C ~ 85°C) and significantly higher lifetime rating (10000 Hrs @ 105°C versus 2000 Hrs @ 85°C). The mechanical envelope is comparable with slightly smaller diameter (0.492" versus 0.512") and height (1.063" versus 1.102"), both fully compatible with the original footprint spacing of 0.197" (5.00 mm). Component selection between these parts may be based on availability, cost, or application-specific performance requirements within the stated parameters.

Frequently Asked Questions (FAQ)
