SPSX561M02R-4 Aluminum Polymer Capacitor Equivalent & Substitute Parts

Part Overview

The SPSX561M02R-4 is a 560 µF, 2 V aluminum polymer capacitor manufactured by Cornell Dubilier Electronics (CDE) in 2917 (7343 Metric) surface mount package. This component is currently classified as obsolete, necessitating direct equivalent substitutes for ongoing design and procurement requirements. The part maintains general-purpose application suitability with specified ratings at 4.5mOhm ESR and 1000 hours lifetime at 105°C.

Substitute Part Grouping Explanation

Substitution validity for the SPSX561M02R-4 is determined by strict equivalence in the following parameters: 560 µF capacitance, 2 V voltage rating, ±20% tolerance, aluminum polymer type, 2917 (7343 Metric) package, and surface mount configuration. All listed substitutes maintain these critical electrical and mechanical specifications.

The substitute parts are classified into two groups based on ESR (Equivalent Series Resistance) characteristics:

Group 1: Direct ESR Match (4.5mOhm)

EEF-SX0D561E4 (Panasonic SP-Cap SX series)

Group 2: Improved ESR (3mOhm)

EEF-GX0D561R (Panasonic SP-Cap GX series)
EEF-GX0D561L (Panasonic SP-Cap GX series)

All substitutes provide active product status and extended thermal lifetime ratings compared to the original obsolete part.

Engineering Selection Recommendations

All three substitute parts are ROHS3 compliant and maintain active product status, ensuring long-term supply chain stability and regulatory compliance. The Panasonic substitutes are direct mechanical fits, with all parts dimensionally identical in footprint. The substitute parts exhibit superior performance characteristics compared to the original SPSX561M02R-4, including extended thermal lifetime (2000 hours versus 1000 hours at 105°C) and expanded operating temperature range (-55°C to 105°C versus -40°C to 105°C).

For applications where the original ESR specification of 4.5mOhm is a design requirement, EEF-SX0D561E4 provides a direct electrical match. For applications tolerant of lower ESR values, EEF-GX0D561R and EEF-GX0D561L offer improved performance through reduced equivalent series resistance (3mOhm) and increased ripple current capability (10.2 A versus 4 A at 100 kHz).

The mechanical height difference of 0.004" (0.10mm) between the original part (2.10mm maximum) and all substitutes (2.00mm maximum) represents a reduction in seated height, requiring verification of assembly clearance constraints in confined mounting environments.

Frequently Asked Questions (FAQ)

Are all substitute parts electrically interchangeable with the SPSX561M02R-4? All substitute parts share identical capacitance (560 µF), voltage rating (2 V), and tolerance (±20%) specifications, making them electrically equivalent for the rated values. Substitute selection should account for ESR and ripple current specifications when these parameters are design-critical.

What is the primary advantage of the Panasonic substitutes over the original CDE part? The Panasonic substitutes provide doubled thermal lifetime (2000 hours versus 1000 hours at 105°C) and expanded operating temperature range (-55°C floor versus -40°C), improving reliability margins. Group 2 substitutes (EEF-GX series) additionally reduce ESR from 4.5mOhm to 3mOhm and increase ripple current capability to 10.2 A.

Do the substitute parts require PCB layout modifications? The 2917 (7343 Metric) package is mechanically identical for all parts, with land pattern compatibility preserved. The 0.004" reduction in maximum seated height (2.10mm to 2.00mm) requires assembly clearance verification only in applications with height-constrained mounting spaces.

Are the substitute parts available in the same packaging format as the original? The Panasonic substitutes are supplied in Tape & Reel (TR) packaging, consistent with surface mount assembly requirements. Inventory levels for all three substitutes exceed 17,000 pieces for EEF-SX0D561E4 and 52,000+ pieces for EEF-GX variants, supporting production requirements.

Which substitute should be selected for new designs? EEF-GX0D561L and EEF-GX0D561R are preferred for new designs due to active product status, superior thermal performance, and reduced ESR characteristics. Both variants are functionally identical and interchangeable; selection between them is independent of electrical performance.
