LPX221M450C9P3 Equivalent & Substitute Parts

Part Overview

The LPX221M450C9P3 is a 220 µF, 450 V aluminum electrolytic capacitor manufactured by Cornell Dubilier Electronics (CDE) in the LPX series. This radial, can-style snap-in capacitor is designed for general-purpose applications requiring high voltage energy storage and filtering. The part is currently active in production with full RoHS3 compliance and REACH unaffected status. Equivalent substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity when the primary part becomes unavailable or when alternative sourcing is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LPX221M450C9P3 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Capacitance value: 220 µF (exact match)
• Voltage rating: 450 V (exact match)
• Tolerance: ±20% (exact match)
• Polarization: Polar (exact match)

Mechanical Equivalence Requirements:

• Package type: Radial, Can - Snap-In (exact match)
• Mounting type: Through Hole (exact match)
• Lead spacing: 10.00 mm (exact match)
• Diameter: 25.00 mm (exact match)

Compliance Requirements:

• RoHS3 Compliant status
• REACH Unaffected status

The substitute part MAL225957221E3 meets all critical electrical and mechanical equivalence criteria. Variations in ESR, lifetime rating, and maximum operating temperature represent performance enhancements rather than compatibility limitations, as the substitute part maintains or exceeds the functional requirements of the primary part within the specified parameter set.

Parameter Comparison

Engineering Selection Recommendations

Primary Part: LPX221M450C9P3

The LPX221M450C9P3 remains the specified component for applications where CDE sourcing is required or preferred. This part is active in production, RoHS3 compliant, and REACH unaffected, meeting all regulatory requirements for current manufacturing standards.

Substitute Part: MAL225957221E3

The MAL225957221E3 from Vishay Beyschlag/Draloric/BC Components is a direct electrical and mechanical equivalent. This substitute part is suitable for applications where:

• The primary part is unavailable or subject to extended lead times
• Procurement from alternative suppliers is required for supply chain resilience
• Inventory replenishment from secondary sources is necessary

Both parts maintain identical electrical specifications (220 µF, 450 V, ±20% tolerance) and mechanical compatibility (radial snap-in package, 10.00 mm lead spacing, 25.00 mm diameter). Both parts are RoHS3 compliant and REACH unaffected. The substitute part features a maximum seated height of 52.00 mm compared to 50.00 mm for the primary part; this 2.00 mm difference is within typical PCB design tolerances for through-hole snap-in capacitor installations. The substitute part also provides extended operating temperature range (-40°C to 105°C versus -40°C to 85°C) and improved lifetime rating (3000 Hrs @ 105°C versus 1000 Hrs @ 85°C), representing performance enhancements.

Frequently Asked Questions (FAQ)

Q: Can MAL225957221E3 be used as a direct replacement for LPX221M450C9P3 on existing PCBs?

A: Yes. Both parts share identical electrical specifications (220 µF, 450 V, ±20% tolerance) and mechanical compatibility (radial snap-in package, 10.00 mm lead spacing, 25.00 mm diameter). The substitute part's maximum seated height of 52.00 mm is 2.00 mm taller than the primary part's 50.00 mm; this difference is within standard PCB design clearances for through-hole snap-in capacitor installations.

Q: Are there any compliance differences between the two parts?

A: No. Both LPX221M450C9P3 and MAL225957221E3 are RoHS3 compliant and REACH unaffected. Both parts meet current regulatory requirements for electronic component manufacturing and use.

Q: What is the difference in ESR between these parts?

A: The LPX221M450C9P3 has an ESR of 904 mOhm @ 120 Hz, while the MAL225957221E3 has an ESR of 530 mOhm @ 100 Hz. The substitute part exhibits lower ESR, which represents improved performance characteristics. ESR measurements are taken at different reference frequencies (120 Hz versus 100 Hz), reflecting manufacturer test standards.

Q: How do the lifetime ratings compare?

A: The LPX221M450C9P3 is rated for 1000 hours at 85°C, while the MAL225957221E3 is rated for 3000 hours at 105°C. The substitute part provides extended operational life, particularly at elevated temperatures. Both ratings are valid for their respective operating conditions.

Q: What is the maximum operating temperature for each part?

A: The LPX221M450C9P3 operates from -40°C to 85°C. The MAL225957221E3 operates from -40°C to 105°C. The substitute part supports a wider operating temperature range, providing greater flexibility for high-temperature applications.

Q: Are both parts available in the same packaging format?

A: Yes. Both parts are supplied in radial, can-style snap-in packages with through-hole mounting. The primary part is packaged individually, while the substitute part is supplied in bulk packaging. Both are suitable for automated and manual assembly processes.

Q: Can I mix these parts in the same production batch?

A: Yes. Both parts meet identical electrical and mechanical specifications for the 220 µF, 450 V, ±20% tolerance rating. Both are RoHS3 compliant and REACH unaffected. Mixing these parts in the same production batch does not create compatibility or regulatory issues, provided PCB layout accommodates the substitute part's maximum seated height of 52.00 mm.
