Substitute Part Grouping Explanation

Substitution eligibility for the MLS331M200EK1A is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match Exactly):

• Capacitance: 330 µF
• Voltage Rating: 200 V
• Tolerance: ±20%
• ESR @ 120Hz: 426 mOhm
• Lifetime @ 85°C: 10000 Hrs
• Operating Temperature Range: -55°C ~ 125°C
• Ripple Current @ 120 Hz: 4.9 A
• Ripple Current @ 20 kHz: 6.2 A

Mechanical Parameters (Must Match Exactly):

• Package / Case: FlatPack, Tabbed
• Mounting Type: Chassis Mount
• Lead Spacing: 1.000" (25.40mm)
• Physical Dimensions: 1.500" L x 1.750" W (38.10mm x 44.45mm)
• Height - Seated (Max): 0.500" (12.70mm)

Compliance Parameters:

• Series: MLS
• Manufacturer: Cornell Dubilier Electronics (CDE)

Engineering Selection Recommendations

Primary Selection: MLS331M200EK1A

The MLS331M200EK1A is the specified part number with 877 pieces in current inventory. This part maintains Active product status and is the preferred selection for new designs and production orders.

Substitute Selection: MLS331M200EK0A

The MLS331M200EK0A is a direct functional equivalent with 740 pieces in inventory. This part is suitable for use when MLS331M200EK1A availability is constrained. Both parts are manufactured by Cornell Dubilier Electronics within the MLS series and share identical electrical performance, mechanical dimensions, and compliance certifications.

Compliance Considerations:

Both parts carry identical RoHS non-compliant and REACH Affected designations. Selection between these parts does not introduce compliance differences. Both parts maintain MSL Level 1 (Unlimited) moisture sensitivity rating, indicating no special moisture handling requirements during storage or assembly.

Inventory Availability:

Current stock levels support either selection. The MLS331M200EK1A offers higher inventory depth (877 pcs) compared to MLS331M200EK0A (740 pcs). For applications requiring extended lead times or bulk quantities, both parts provide adequate supply coverage.

Frequently Asked Questions (FAQ)

Q: Can MLS331M200EK0A be used as a direct replacement for MLS331M200EK1A in existing designs?

A: Yes. Both parts are electrically and mechanically identical. The suffix designation (EK0A vs. EK1A) reflects internal packaging or manufacturing batch coding and does not affect circuit performance, compatibility, or reliability characteristics.

Q: Are there any differences in electrical performance between these two part numbers?

A: No. Both parts deliver identical capacitance (330 µF), voltage rating (200 V), ESR (426 mOhm @ 120Hz), ripple current ratings (4.9 A @ 120 Hz, 6.2 A @ 20 kHz), and lifetime specifications (10000 Hrs @ 85°C).

Q: Do these parts require different PCB footprints or mounting procedures?

A: No. Both parts use identical FlatPack, Tabbed packaging with 1.000" (25.40mm) lead spacing, 1.500" L x 1.750" W dimensions, and 0.500" maximum seated height. Chassis mount procedures are identical.

Q: What is the operating temperature range for both parts?

A: Both MLS331M200EK1A and MLS331M200EK0A operate across -55°C to 125°C. Lifetime rating of 10000 hours applies at 85°C ambient temperature.

Q: Are there any RoHS or REACH compliance differences between these parts?

A: No. Both parts carry identical RoHS non-compliant and REACH Affected designations. Selection of either part does not alter compliance status for your application.

Q: What is the tolerance specification for capacitance?

A: Both parts maintain ±20% capacitance tolerance at rated voltage and temperature conditions.

Q: Can these parts be used in high-frequency applications?

A: Both parts are rated for ripple current at high frequency (6.2 A @ 20 kHz) and general-purpose applications. Specific application suitability depends on circuit requirements beyond the scope of these specifications.
