LPX471M350H5P3

Part Overview

The LPX471M350H5P3 is a 470 µF, 350 V aluminum electrolytic capacitor manufactured by Cornell Dubilier Electronics (CDE) in a radial, can snap-in package configuration. This component is classified as Active and serves general-purpose applications requiring polarized capacitive storage with through-hole mounting. Finding alternative models becomes necessary when supply constraints occur, when higher voltage ratings are beneficial for system margin, or when improved thermal performance characteristics are required for extended operational lifespans.

Substitute Part Grouping Explanation

Substitution of the LPX471M350H5P3 is qualified on the basis of electrical and mechanical compatibility within the aluminum electrolytic capacitor category. The following criteria determine valid substitutes:

Critical Parameters (Must Match):

• Capacitance: 470 µF
• Tolerance: ±20%
• Polarization: Polar
• Package / Case: Radial, Can - Snap-In
• Mounting Type: Through Hole
• Lead Spacing: 0.394" (10.00 mm)
• Physical Diameter: 1.378" (35.00 mm)

Allowable Variance Parameters:

• Voltage - Rated: Equal to or greater than 350 V
• Operating Temperature Range: Equal to or greater than -40°C ~ 85°C
• ESR @ Rated Frequency: Lower or equivalent values are acceptable
• Lifetime @ Temperature: Higher values indicate improved thermal performance
• RoHS / REACH Compliance: Must maintain ROHS3 and REACH Unaffected status

The MAL225966471E3 qualifies as a direct electrical and mechanical substitute based on matching capacitance, tolerance, polarization, package type, mounting method, lead spacing, and physical diameter specifications, while offering superior voltage rating (400 V), operating temperature range (-40°C ~ 105°C), and lifetime ratings (3000 Hrs @ 105°C).

Engineering Selection Recommendations

LPX471M350H5P3 Selection Criteria: The LPX471M350H5P3 remains the primary specification when the original design parameters specify a maximum height of 1.378" and an operating temperature ceiling of 85°C. This part is Active and ROHS3 compliant, meeting current environmental regulations. Availability of 724 pcs ensures near-term procurement capability.

MAL225966471E3 Selection Criteria: The MAL225966471E3 provides enhanced performance characteristics and is selected when system designs permit the maximum seated height of 1.457" and can utilize the extended operating temperature range to 105°C. This part delivers lower ESR (320 mOhm @ 100 Hz versus 423 mOhm @ 120 Hz), higher voltage rating (400 V versus 350 V), and extended lifetime (3000 Hrs @ 105°C versus 1000 Hrs @ 85°C). Both parts are Active, ROHS3 compliant, and REACH unaffected, meeting all compliance requirements. Availability of 2113 pcs provides robust supply.

Frequently Asked Questions (FAQ)

Q: Can the MAL225966471E3 replace the LPX471M350H5P3 in all applications? A: Direct substitution is valid when the printed circuit board layout permits a maximum seated height of 1.457" (the MAL225966471E3 is 0.079" taller). The electrical performance of the MAL225966471E3 exceeds the LPX471M350H5P3 specifications in voltage rating, ESR, and thermal lifetime.

Q: Are there any mechanical incompatibilities between these parts? A: Both parts maintain identical lead spacing (0.394" / 10.00 mm) and physical diameter (1.378" / 35.00 mm), ensuring interchangeable mounting hole positioning. The only dimensional difference is the seated height, which must be confirmed against PCB clearance requirements.

Q: Does the voltage rating difference affect substitution? A: The MAL225966471E3 operates at 400 V, which exceeds the LPX471M350H5P3 design specification of 350 V. Higher voltage-rated capacitors function correctly in lower-voltage applications and provide additional system design margin.

Q: Are both parts compliant with environmental regulations? A: Both the LPX471M350H5P3 and MAL225966471E3 are ROHS3 compliant and REACH unaffected, meeting current environmental and hazardous substance restrictions.

Q: What is the practical difference in ESR between these parts? A: The MAL225966471E3 exhibits 320 mOhm @ 100 Hz compared to the LPX471M350H5P3 at 423 mOhm @ 120 Hz. Lower ESR reduces heat generation and improves ripple current handling capability, providing benefits in high-frequency or high-current applications.

Q: Does thermal rating affect interchangeability? A: The MAL225966471E3 extends the operating temperature range to 105°C and provides 3000 hours lifetime @ 105°C versus 1000 hours @ 85°C for the LPX471M350H5P3. Applications operating near 85°C benefit from the MAL225966471E3's extended thermal performance.
