SLP221M450C4P3 Equivalent & Substitute Parts

Part Overview

The SLP221M450C4P3 is a 220 µF, 450 V aluminum electrolytic capacitor manufactured by Cornell Dubilier Electronics (CDE) in a radial, can snap-in package. This component is classified as Active product status and is designed for general-purpose applications requiring high-voltage energy storage and filtering. The part operates across a temperature range of -25°C to 105°C with a rated lifetime of 3000 hours at 105°C.

Equivalent and substitute parts are identified when design requirements necessitate alternative sourcing due to inventory constraints, supply chain considerations, or when performance characteristics of substitute models meet or exceed the original specification within the allowed parameter tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SLP221M450C4P3 is determined by strict adherence to the following electrical and mechanical parameters:

Critical Parameters (Must Match):

• Capacitance: 220 µF
• Voltage Rating: 450 V
• Tolerance: ±20%
• Polarization: Polar
• Package Type: Radial, Can - Snap-In
• Mounting Type: Through Hole
• Lead Spacing: 0.394" (10.00mm)
• Operating Temperature Range: -25°C to 105°C
• RoHS Status: ROHS3 Compliant

Allowable Variations:

• Lifetime @ 105°C: Equal to or greater than 3000 hours
• Physical Height: Variations permitted within mechanical envelope constraints
• Ripple Current Ratings: Variations permitted provided rated values are specified
• ESR (Equivalent Series Resistance): Variations permitted when specified

All four substitute parts meet these criteria and are classified as direct equivalents for the SLP221M450C4P3.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts are classified as Active product status and maintain full ROHS3 compliance and REACH unaffected status, consistent with the SLP221M450C4P3 original specification.

450MXG220MEFCSN25X40 (Rubycon MXG Series): This substitute provides equivalent 3000-hour lifetime rating at 105°C with reduced physical height (42.00mm versus 47.00mm). Ripple current capability at 120 Hz is 1.44 A, exceeding the original part specification. This configuration is suitable for applications where vertical space constraints exist within the mechanical envelope.

450VXH220MEFCSN25X35 (Rubycon VXH Series): This substitute provides extended 5000-hour lifetime at 105°C with the most compact physical height (37.00mm). Ripple current capability at 120 Hz is 1.37 A. The extended lifetime rating provides enhanced reliability margin for long-term operation.

ELXS451VSN221MQ40S (Chemi-Con LXS Series): This substitute provides extended 5000-hour lifetime at 105°C with physical height of 42.50mm. Ripple current capability at 120 Hz is 1.2 A. Moisture Sensitivity Level is Not Applicable, indicating enhanced environmental robustness.

LGW2W221MELA45 (Nichicon LGW Series): This substitute provides equivalent 3000-hour lifetime rating at 105°C with physical height of 45.00mm. Ripple current capability at 120 Hz is 1.55 A, the highest among all substitutes. Moisture Sensitivity Level is Not Applicable.

Selection among these substitutes is determined by application-specific requirements regarding physical height constraints, ripple current demands, and desired operational lifetime.

Frequently Asked Questions (FAQ)

Q: Can the 450VXH220MEFCSN25X35 be used as a direct replacement for the SLP221M450C4P3?

A: Yes. The 450VXH220MEFCSN25X35 meets all critical electrical parameters: 220 µF capacitance, 450 V voltage rating, ±20% tolerance, polar configuration, and radial snap-in package with 10.00mm lead spacing. The reduced physical height (37.00mm versus 47.00mm) is compatible with applications where the original part's height does not exceed available space. The extended 5000-hour lifetime at 105°C exceeds the original 3000-hour specification.

Q: What is the primary difference between the Rubycon MXG and VXH series substitutes?

A: The primary differences are physical height and lifetime rating. The MXG series (450MXG220MEFCSN25X40) provides 3000-hour lifetime at 42.00mm height. The VXH series (450VXH220MEFCSN25X35) provides 5000-hour lifetime at 37.00mm height. Both maintain identical electrical specifications of 220 µF, 450 V, and ±20% tolerance.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All four substitute parts are ROHS3 Compliant and REACH Unaffected, matching the environmental compliance status of the SLP221M450C4P3.

Q: Does the ELXS451VSN221MQ40S have a different physical diameter than other substitutes?

A: The ELXS451VSN221MQ40S has a diameter of 1.000" (25.40mm) compared to 0.984" (25.00mm) for the original part and three other substitutes. This 0.40mm difference is within typical mechanical tolerance ranges for snap-in capacitor installations but should be verified against specific PCB layout constraints.

Q: Which substitute has the highest ripple current rating at 120 Hz?

A: The LGW2W221MELA45 (Nichicon LGW Series) provides the highest ripple current rating at 120 Hz of 1.55 A, compared to the original part's 1.12 A specification.

Q: Can substitutes with extended lifetime ratings (5000 hours) be used in applications designed for 3000-hour rated components?

A: Yes. Extended lifetime ratings represent enhanced performance characteristics and are compatible with applications specified for shorter lifetimes. The 450VXH220MEFCSN25X35 and ELXS451VSN221MQ40S, both rated for 5000 hours at 105°C, are suitable for any application requiring minimum 3000-hour operation.
