Key Parameters

Substitute Part Grouping Explanation

Substitution of the 6SXB47M is determined by the following critical parameters:

• Capacitance Value: 47 µF (exact match required)
• Package Footprint: 2917 (7343 Metric) (physical compatibility)
• Mounting Type: Surface Mount (assembly compatibility)
• Tolerance: ±20% (electrical specification match)
• Type: Aluminum Polymer (technology class)
• Operating Temperature Range: -55°C ~ 105°C (environmental compatibility)
• RoHS Compliance: ROHS3 Compliant (regulatory requirement)

The Panasonic EEF-CS1A470R qualifies as a substitute based on matching capacitance, package, mounting type, tolerance, polymer technology, temperature range, and RoHS compliance. Voltage rating and ESR differ but remain within acceptable substitution parameters for general-purpose applications.

Engineering Selection Recommendations

The Panasonic EEF-CS1A470R serves as a direct substitute for the obsolete Rubycon 6SXB47M in applications where the circuit design accommodates a 10 V rated capacitor in place of the original 6.3 V specification. Both components maintain ROHS3 compliance and identical package footprints, ensuring PCB-level compatibility without layout modifications.

The EEF-CS1A470R carries "Not For New Designs" status, indicating limited long-term availability. For new product development, evaluation of current-generation polymer capacitor alternatives with active production status is recommended.

Frequently Asked Questions (FAQ)

Q: Can the Panasonic EEF-CS1A470R directly replace the Rubycon 6SXB47M without circuit modification?

A: Physical and electrical compatibility exists for applications where the circuit operates at voltages below 6.3 V. The higher voltage rating (10 V) of the substitute provides margin. ESR difference (40 mOhm vs. 13 mOhm) may affect ripple current performance in high-frequency applications; circuit validation is necessary.

Q: Are the package dimensions identical between these parts?

A: Both components use the 2917 (7343 Metric) package with identical footprint dimensions (7.30mm L x 4.30mm W). Height differs: 6SXB47M seated height is 1.90mm maximum; EEF-CS1A470R seated height is 1.20mm maximum. This height difference may affect clearance in space-constrained designs.

Q: What is the significance of the "Obsolete" and "Not For New Designs" product statuses?

A: "Obsolete" indicates the Rubycon part is no longer manufactured. "Not For New Designs" indicates the Panasonic substitute has limited production commitment. For applications requiring long-term component availability, alternative suppliers with active production status should be evaluated.

Q: Do both parts meet the same compliance requirements?

A: Both components are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component use in regulated markets.
