Key Parameters

Substitute Part Grouping Explanation

Substitution of the EEF-SL0J560R is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Capacitance value: 56 µF (exact match required)
• Tolerance: ±20% (standard polymer capacitor tolerance)
• Package / Case: 2917 (7343 Metric) (physical and electrical footprint compatibility)
• Mounting Type: Surface Mount (assembly process compatibility)
• Type: Polymer (electrical performance characteristics)

Allowable Variation Parameters:

• Voltage - Rated: Substitute parts may have equal or higher voltage ratings, provided the application circuit does not exceed the original 6.3 V specification
• ESR: Substitute parts may have equal or lower ESR values without circuit impact
• Lifetime @ Temperature: Substitute parts may have equal or longer lifetime ratings
• Operating Temperature Range: Substitute parts may have equal or wider temperature ranges
• Ripple Current @ 100 kHz: Substitute parts may have equal or higher ripple current capability

The EEF-CX1D560R qualifies as a direct substitute based on matching capacitance, tolerance, package, mounting type, and polymer construction, while offering improved electrical performance through higher voltage rating, lower ESR, extended lifetime, and increased ripple current capability.

Parameter Comparison

Engineering Selection Recommendations

The EEF-CX1D560R serves as a direct functional substitute for the obsolete EEF-SL0J560R in applications operating at or below 6.3 V. Both components are manufactured by Panasonic Electronic Components and share identical capacitance, tolerance, and package specifications.

The EEF-CX1D560R is classified as "Not For New Designs," indicating limited long-term availability. For new product development, evaluation of current-generation polymer capacitor alternatives in the same package and capacitance range is recommended.

The EEF-CX1D560R provides enhanced performance characteristics including higher voltage rating (20 V versus 6.3 V), extended thermal lifetime (2000 hours versus 1000 hours at 105°C), and wider operating temperature range (-55°C to 105°C versus -40°C to 105°C). The substitute part exhibits higher ESR (40 mOhm versus 9 mOhm) and marginally increased seated height (0.075" versus 0.071"), which must be evaluated against specific circuit requirements and PCB layout constraints.

The EEF-CX1D560R carries ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component procurement.

Frequently Asked Questions (FAQ)

Q: Can the EEF-CX1D560R be used as a direct replacement for the EEF-SL0J560R?

A: Yes, the EEF-CX1D560R is electrically and mechanically compatible with the EEF-SL0J560R in applications operating at 6.3 V or below. Both components share identical capacitance (56 µF), tolerance (±20%), package (2917 / 7343 Metric), and mounting type (Surface Mount). The substitute part's higher voltage rating does not affect compatibility in lower-voltage circuits.

Q: What is the impact of the higher ESR in the EEF-CX1D560R?

A: The EEF-CX1D560R exhibits 40 mOhm ESR compared to 9 mOhm in the original part. Higher ESR increases resistive losses and heat generation under ripple current conditions. Circuit designs sensitive to ESR performance or thermal dissipation must evaluate whether this increase affects system operation. Applications with moderate ripple current demands typically tolerate this variation.

Q: Does the increased seated height of the EEF-CX1D560R create PCB layout issues?

A: The EEF-CX1D560R seated height is 0.075" (1.90 mm) compared to 0.071" (1.80 mm) for the original part. This 0.004" (0.10 mm) difference is negligible for most PCB designs. Verification against specific board clearance requirements and component placement constraints is necessary only in space-constrained applications.

Q: Are there compliance or regulatory differences between these parts?

A: The EEF-CX1D560R carries ROHS3 compliance and REACH unaffected status. The original EEF-SL0J560R specifications do not include explicit compliance documentation in the provided data. Both parts share identical ECCN (EAR99) and HTSUS (8532.22.0020) classifications.

Q: What is the significance of the "Not For New Designs" status of the EEF-CX1D560R?

A: "Not For New Designs" indicates that Panasonic Electronic Components does not recommend this part for new product development due to limited future availability or planned discontinuation. Existing inventory may support legacy product maintenance and repair. New designs should evaluate current-generation alternatives from Panasonic or other manufacturers offering equivalent 56 µF, 6.3 V or higher polymer capacitors in the 2917 package.
