SLPX561M350E7P3 Equivalent & Substitute Parts

Part Overview

The SLPX561M350E7P3 is a 560 µF, 350 V aluminum electrolytic capacitor manufactured by Cornell Dubilier Electronics (CDE) in a radial, can snap-in package. This component is classified as Active and is designed for general-purpose applications requiring high-capacitance energy storage at elevated voltage ratings. The part is ROHS3 compliant and REACH unaffected, meeting current environmental standards.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained within the allowed tolerances and specifications for this product category. Substitution becomes necessary due to inventory availability, supply chain considerations, or manufacturing discontinuation while maintaining functional equivalence in the target application.

Substitute Part Grouping Explanation

Substitution of the SLPX561M350E7P3 is based on strict equivalence of the following critical parameters:

Electrical Parameters:

Capacitance: 560 µF (exact match required)
Voltage Rating: 350 V (exact match required)
Tolerance: ±20% (exact match required)
Lifetime: 3000 Hrs @ 85°C (exact match required)
Operating Temperature Range: -25°C ~ 85°C (exact match required)
Polarization: Polar (exact match required)

Mechanical Parameters:

Package Type: Radial, Can - Snap-In (exact match required)
Lead Spacing: 0.394" / 10.00 mm (exact match required)
Diameter: 1.181" / 30.00 mm (exact match required)
Height - Seated (Max): 1.654" / 42.00 mm (exact match required)
Mounting Type: Through Hole (exact match required)

Compliance Parameters:

RoHS Status: ROHS3 Compliant (exact match required)
REACH Status: REACH Unaffected (exact match required)

Substitute parts must match all parameters listed above. Variations in ESR (Equivalent Series Resistance) or ripple current specifications do not disqualify a part from substitution provided all critical electrical and mechanical parameters remain equivalent.

Selection between these two parts is based on:

Availability: The LLS2V561MELB has 1048 pieces in stock compared to 643 pieces for the SLPX561M350E7P3, providing greater supply availability.

Compliance: Both parts meet ROHS3 and REACH requirements, ensuring regulatory compliance in equivalent applications.

Functional Equivalence: All critical parameters—capacitance, voltage rating, tolerance, lifetime, operating temperature range, and physical dimensions—are identical. Both parts are suitable for general-purpose applications requiring 560 µF capacitance at 350 V with snap-in mounting.

Manufacturing Continuity: Both manufacturers maintain Active product status, ensuring continued availability and support for these components.

Frequently Asked Questions (FAQ)

Q: Can the LLS2V561MELB replace the SLPX561M350E7P3 in my application?

A: Yes. The LLS2V561MELB meets all critical electrical and mechanical parameters required for direct substitution. Both parts have identical capacitance (560 µF), voltage rating (350 V), tolerance (±20%), lifetime (3000 Hrs @ 85°C), operating temperature range (-25°C ~ 85°C), and physical dimensions (1.181" diameter, 1.654" height, 0.394" lead spacing). Both are snap-in radial through-hole components.

Q: Are there differences in ESR between these parts?

A: The SLPX561M350E7P3 specifies 355 mOhm @ 120 Hz. The LLS2V561MELB does not provide an ESR specification in the available data. ESR differences do not disqualify substitution when all other critical parameters are equivalent.

Q: Do both parts have the same ripple current rating?

A: Both parts specify 2.73 A @ 120 Hz. At 20 kHz, the SLPX561M350E7P3 specifies 4.01 A, while the LLS2V561MELB specifies 3.9039 A @ 50 kHz. These variations do not affect substitution eligibility when the primary ripple current specification at 120 Hz is identical.

Q: Are the physical dimensions identical?

A: Yes. Both parts have identical lead spacing (0.394" / 10.00 mm), diameter (1.181" / 30.00 mm), and maximum seated height (1.654" / 42.00 mm). Both are snap-in packages suitable for through-hole mounting on standard PCB layouts.

Q: Do both parts meet environmental compliance standards?

A: Yes. Both the SLPX561M350E7P3 and LLS2V561MELB are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the difference between these manufacturers?

A: Cornell Dubilier Electronics (CDE) and Nichicon are both established manufacturers of aluminum electrolytic capacitors. The SLPX series (CDE) and LLS series (Nichicon) are equivalent product lines with identical specifications for this 560 µF, 350 V rating.
