SLPX331M315C5P3 Equivalent & Substitute Parts

Part Overview

The SLPX331M315C5P3 is a 330 µF, 315 V aluminum electrolytic capacitor manufactured by Cornell Dubilier Electronics (CDE) in a radial, can snap-in package. This component is designed for general-purpose applications requiring stable capacitance and extended operational life at elevated temperatures. The part maintains Active product status with 737 units in current inventory.

Substitute parts become necessary when original stock is unavailable, when design requirements permit higher voltage ratings, or when alternative manufacturer sourcing is required for supply chain continuity. Equivalent parts must maintain identical or superior electrical and mechanical characteristics within the specified parameter tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SLPX331M315C5P3 is determined by strict adherence to the following parameters:

Mandatory Match Parameters:

• Capacitance value: 330 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Lead spacing: 10.00 mm (exact match required)
• Can diameter: 25.00 mm (exact match required)
• Height seated maximum: 37.00 mm (exact match required)
• Package type: Radial, Can - Snap-In (exact match required)
• Mounting type: Through Hole (exact match required)
• Polarization: Polar (exact match required)

Allowable Upgrade Parameters:

• Voltage rating: Must equal or exceed 315 V
• Operating temperature range: Must maintain -25°C ~ 85°C minimum
• Lifetime at temperature: Must equal or exceed 3000 Hrs @ 85°C

The substitute part LLS2V331MELA meets all mandatory parameters and provides an upgraded voltage rating of 350 V, which exceeds the original 315 V specification while maintaining all physical and electrical compatibility requirements.

Parameter Comparison

Engineering Selection Recommendations

The LLS2V331MELA manufactured by Nichicon is a direct substitute for the SLPX331M315C5P3. Both components are Active products with current inventory availability and maintain identical compliance certifications.

Selection Basis:

The substitute part satisfies all mandatory electrical and mechanical parameters. The 350 V voltage rating of the LLS2V331MELA exceeds the original 315 V specification, providing enhanced voltage margin without compromising any other performance characteristics. This upgrade is electrically compatible with circuits designed for the original 315 V component.

Both parts maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory alignment for current manufacturing standards. The identical operating temperature range (-25°C ~ 85°C) and lifetime specification (3000 Hrs @ 85°C) confirm thermal performance equivalence.

Physical dimensions, lead spacing, and package configuration are identical, ensuring direct mechanical compatibility in through-hole PCB applications with snap-in mounting requirements.

Frequently Asked Questions (FAQ)

Q: Can the LLS2V331MELA replace the SLPX331M315C5P3 in existing designs?

A: Yes. The LLS2V331MELA is electrically and mechanically compatible. All mandatory parameters match, and the higher voltage rating (350 V vs. 315 V) provides additional design margin without affecting circuit operation.

Q: Are there physical dimension differences between these parts?

A: No. Both components share identical lead spacing (10.00 mm), can diameter (25.00 mm), and seated height (37.00 mm). They are mechanically interchangeable in through-hole snap-in applications.

Q: Do both parts meet current compliance requirements?

A: Yes. Both the SLPX331M315C5P3 and LLS2V331MELA are ROHS3 compliant and REACH Unaffected, meeting current regulatory standards for electronic component manufacturing.

Q: What is the difference in ripple current handling?

A: The LLS2V331MELA provides slightly higher ripple current capacity at 120 Hz (1.97 A vs. 1.94 A), representing a marginal performance improvement. Both parts are rated for 3000 hours at 85°C.

Q: Can I use the substitute part if my circuit operates below 315 V?

A: Yes. The 350 V rating of the LLS2V331MELA is suitable for any application rated at or below 315 V. Higher voltage ratings do not restrict operation at lower voltages.

Q: Are there inventory considerations for selecting between these parts?

A: The SLPX331M315C5P3 has 737 units in stock, while the LLS2V331MELA has 707 units available. Both maintain adequate inventory for current procurement needs.
