LPX101M450C3P3 Equivalent & Substitute Parts

Part Overview

The LPX101M450C3P3 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 within the allowed tolerance parameters for this capacitor category. Substitution becomes necessary due to inventory availability, supply chain considerations, or application-specific performance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LPX101M450C3P3 is determined by strict adherence to the following critical parameters:

Critical Electrical Parameters:

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

Critical Mechanical Parameters:

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

Compliance Parameters:

• RoHS3 compliance (required for substitution)
• REACH unaffected status (required for substitution)

Substitute parts must satisfy all critical parameters listed above. Physical dimensions (diameter and height) may vary within industry-standard tolerances for snap-in can capacitors, provided the lead spacing and mounting footprint remain compatible with the original design.

Parameter Comparison

Engineering Selection Recommendations

The MAL225957101E3 (Vishay Beyschlag/Draloric/BC Components) qualifies as a direct substitute for the LPX101M450C3P3 based on matching critical electrical and mechanical parameters: identical capacitance (100 µF), rated voltage (450 V), tolerance (±20%), polarization (polar), mounting type (through hole), package style (radial, can - snap-in), and lead spacing (0.394" / 10.00mm).

Both parts maintain full RoHS3 compliance and REACH unaffected status, meeting regulatory requirements for equivalent component selection.

Physical dimensions differ slightly: the Vishay part has a smaller diameter (0.866" vs. 0.984") and slightly greater height (1.260" vs. 1.181"). These dimensional variations are within acceptable tolerances for snap-in can capacitor designs and do not affect PCB footprint compatibility given the identical lead spacing.

The Vishay substitute demonstrates enhanced performance characteristics: lower ESR (1.12 Ohm @ 100Hz vs. 1.989 Ohm @ 120Hz), extended operating temperature range (-40°C ~ 105°C vs. -40°C ~ 85°C), and longer rated lifetime (3000 Hrs @ 105°C vs. 1000 Hrs @ 85°C). These characteristics indicate suitability for applications requiring improved thermal stability and extended service life.

Frequently Asked Questions (FAQ)

Q: Can the MAL225957101E3 be used as a direct replacement for the LPX101M450C3P3 on existing PCBs?

A: Yes. Both parts share identical lead spacing (0.394" / 10.00mm), mounting type (through hole), and package style (radial, can - snap-in). Physical diameter and height differences do not affect PCB footprint compatibility. Verify clearance in the enclosure or mounting area, as the Vishay part has a smaller diameter but slightly greater height.

Q: Are there any electrical performance differences between these parts?

A: Both parts meet the same capacitance (100 µF), voltage rating (450 V), and tolerance (±20%) specifications. The Vishay substitute exhibits lower ESR and higher ripple current ratings at both low and high frequencies, indicating improved electrical performance. Operating temperature range and lifetime ratings are also superior in the substitute part.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the LPX101M450C3P3 and MAL225957101E3 are RoHS3 compliant and REACH unaffected, meeting equivalent regulatory requirements for component selection.

Q: What is the significance of the different ESR values?

A: ESR (Equivalent Series Resistance) affects capacitor performance in filtering and ripple current applications. The Vishay substitute has lower ESR (1.12 Ohm @ 100Hz vs. 1.989 Ohm @ 120Hz), which generally results in improved filtering efficiency and reduced heat generation under ripple current conditions.

Q: Can I use the MAL225957101E3 in applications rated for the full -40°C ~ 85°C range of the original part?

A: Yes. The Vishay substitute operates across -40°C ~ 105°C, which fully encompasses the original part's operating range. The extended temperature capability of the substitute does not create compatibility issues for applications within the original temperature specification.

Q: Are there inventory or lead time considerations for these parts?

A: Inventory levels differ between manufacturers. The LPX101M450C3P3 has 842 pieces in stock, while the MAL225957101E3 has 3165 pieces available. Consult current distributor inventory for real-time availability.
