LPX101M450A5P3 Equivalent & Substitute Parts

Part Overview

The LPX101M450A5P3 is a 100 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. Substitute parts are identified when equivalent electrical and mechanical specifications are met, enabling component interchangeability in circuit designs where the original part becomes unavailable or inventory constraints require alternative sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LPX101M450A5P3 is determined by strict adherence to the following parameters:

Critical Electrical Parameters:

• Capacitance value: 100 µF (exact match required)
• Rated voltage: 450 V (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)

Critical Mechanical Parameters:

• Package type: Radial, Can - Snap-In (exact match required)
• Mounting type: Through Hole (exact match required)
• Lead spacing: 0.394" (10.00mm) (exact match required)
• Diameter: 0.866" (22.00mm) (exact match required)

Compliance Parameters:

• RoHS3 Compliant status (required for regulatory alignment)
• REACH Unaffected status (required for regulatory alignment)

The substitute part MAL225957101E3 meets all critical electrical, mechanical, and compliance requirements. Variations in secondary parameters such as ESR, ripple current ratings, lifetime specifications, and height dimensions do not disqualify substitution when primary parameters align.

Parameter Comparison

Engineering Selection Recommendations

Substitution Validity:

The MAL225957101E3 is a valid direct substitute for the LPX101M450A5P3 based on matching critical electrical and mechanical parameters. Both parts are active products with current manufacturing status, ensuring long-term availability and supply chain stability.

Regulatory Compliance:

Both the main part and substitute meet RoHS3 compliance requirements and are REACH unaffected, satisfying regulatory requirements for applications in restricted substance environments.

Performance Considerations:

The substitute part demonstrates equivalent or superior performance characteristics in secondary parameters. The MAL225957101E3 exhibits lower ESR (1.12 Ohm @ 100Hz versus 1.989 Ohm @ 120Hz) and extended lifetime rating (3000 Hrs @ 105°C versus 1000 Hrs @ 85°C), indicating enhanced thermal stability and reduced ripple current losses. The operating temperature range of the substitute (-40°C ~ 105°C) exceeds that of the main part (-40°C ~ 85°C).

Physical Compatibility:

The substitute part is 3.00mm shorter in seated height (32.00mm versus 35.00mm) while maintaining identical lead spacing (10.00mm) and diameter (22.00mm). This dimensional difference must be verified against circuit board layout constraints and enclosure clearances before implementation.

Packaging and Inventory:

The substitute part is available in bulk packaging with higher inventory levels (3165 pieces versus 669 pieces), supporting production volume requirements and reducing lead time risk.

Frequently Asked Questions (FAQ)

Q: Can MAL225957101E3 be used as a direct replacement for LPX101M450A5P3 in existing circuit designs?

A: Yes, MAL225957101E3 is a direct substitute when all critical parameters match: 100 µF capacitance, 450 V rated voltage, ±20% tolerance, polar configuration, radial snap-in package, through-hole mounting, 10.00mm lead spacing, and 22.00mm diameter. Physical board layout must accommodate the 3.00mm height difference.

Q: What are the key electrical parameters that must match for substitution?

A: Capacitance (100 µF), rated voltage (450 V), tolerance (±20%), and polarization (polar) must match exactly. These parameters determine circuit functionality and safety margins.

Q: Does the lower ESR of the substitute part affect circuit performance?

A: Lower ESR in the substitute part (1.12 Ohm @ 100Hz) reduces ripple voltage and heat generation compared to the main part (1.989 Ohm @ 120Hz). This represents an improvement in performance characteristics and does not create compatibility issues.

Q: Is the height difference between the two parts a concern?

A: The substitute part is 3.00mm shorter (32.00mm versus 35.00mm seated height). This difference must be evaluated against circuit board layout, component spacing, and enclosure clearances. No electrical impact occurs from this dimensional variation.

Q: Are both parts compliant with current regulatory standards?

A: Yes, both LPX101M450A5P3 and MAL225957101E3 are RoHS3 compliant and REACH unaffected, meeting current regulatory requirements for restricted substance control.

Q: What is the inventory status of each part?

A: LPX101M450A5P3 has 669 pieces in stock. MAL225957101E3 has 3165 pieces in stock, providing greater availability and shorter lead times for production requirements.

Q: Can the substitute part operate at higher temperatures than the main part?

A: Yes, the substitute part operates across -40°C ~ 105°C, exceeding the main part's -40°C ~ 85°C range. The substitute also provides extended lifetime rating (3000 Hrs @ 105°C versus 1000 Hrs @ 85°C), indicating superior thermal performance.

Q: Are there any mechanical compatibility issues with the snap-in mounting?

A: No mechanical compatibility issues exist. Both parts use identical radial, can-style snap-in packages with matching lead spacing (10.00mm) and diameter (22.00mm), ensuring compatibility with standard through-hole mounting hardware.
