MLS331M200EK1D Equivalent & Substitute Parts

Part Overview

The MLS331M200EK1D is a 330 µF, 200 V aluminum electrolytic capacitor manufactured by Cornell Dubilier Electronics (CDE) in FlatPack, Tabbed configuration. This component is classified as Active product status and serves general-purpose applications requiring high-voltage energy storage and filtering. The part is designed for chassis mount installation with rated lifetime of 10,000 hours at 85°C operating temperature.

Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and environmental specifications are maintained across the component family. Substitution becomes necessary due to inventory availability, supply chain continuity, or manufacturing transitions within the same product series.

Key Parameters

Substitute Part Grouping Explanation

Substitution of aluminum electrolytic capacitors within the MLS series is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Capacitance value: 330 µF (exact match required)
• Voltage rating: 200 V (exact match required)
• Tolerance: ±20% (exact match required)
• ESR @ 120 Hz: 426 mOhm (exact match required)
• Lifetime @ 85°C: 10,000 Hrs (exact match required)
• Ripple current specifications at both 120 Hz and 20 kHz (exact match required)

Mechanical Compatibility Criteria:

• Package type: FlatPack, Tabbed (exact match required)
• Lead spacing: 1.000" / 25.40 mm (exact match required)
• Physical dimensions: 1.500" L x 1.750" W / 38.10 mm x 44.45 mm (exact match required)
• Height - Seated (Max): 0.500" / 12.70 mm (exact match required)
• Mounting type: Chassis Mount (exact match required)

Environmental & Compliance Criteria:

• Operating temperature range: -55°C to 125°C (exact match required)
• Polarization: Polar (exact match required)
• Series designation: MLS (exact match required)
• Product status: Active (exact match required)

Substitute parts must satisfy all criteria simultaneously. No parameter relaxation or tolerance stacking is permitted.
