Substitute Part Grouping Explanation

Substitution eligibility is determined by the following core parameters: capacitance value (47 µF), voltage rating (minimum 16 V), package footprint compatibility (5.00 mm diameter, 5.30 mm × 5.30 mm land size), surface mount mounting type, and polar configuration. Parts are grouped into categories based on product status and performance enhancements.

MFR Recommended Substitutes maintain the same capacitance and voltage while offering improved lifetime or operating temperature range. These parts are actively produced and suitable for new designs.

Upgrade Substitutes provide enhanced electrical performance (lower ESR, higher ripple current capability) or extended lifetime at elevated temperatures while maintaining mechanical and electrical compatibility.

Similar Substitutes share the same core electrical parameters but may have different physical dimensions or lifetime ratings, requiring PCB layout verification.

Parametric Equivalents match the original part specifications exactly and serve as direct replacements with identical performance characteristics.

Direct Substitutes from alternative manufacturers meet the same electrical and mechanical requirements with equivalent performance.

Engineering Selection Recommendations

For Active Production (New Designs): EEE-FPC470UAR, EEE-HAC470WAR, and EEE-HBC470UAR are recommended. All three are Panasonic parts with Active product status and ROHS3 compliance. EEE-FPC470UAR and EEE-HBC470UAR offer 2000-hour lifetime at 105°C, providing extended reliability. EEE-HAC470WAR maintains 1000-hour lifetime at 105°C with lower inventory risk.

For Voltage Margin Applications: EEE-FN1E470R provides 25 V rating with 2000-hour lifetime at 105°C and extended temperature range (-55°C to 105°C), suitable for applications requiring higher voltage headroom.

For Direct Replacement (Same Footprint): EEE-1CA470WAR is the parametric equivalent with Active status and ROHS3 compliance, maintaining identical 5.00 mm × 5.50 mm dimensions.

For Alternative Manufacturer Sourcing: UCL1C470MCL6GS (Nichicon) provides equivalent electrical and mechanical specifications with Active status and 2000-hour lifetime at 105°C.

End-of-Life Consideration: 16SEV47M5X5.5 (Rubycon) carries Last Time Buy status and should not be selected for new designs despite meeting electrical requirements.

Frequently Asked Questions (FAQ)

Q: Can EEE-FN1E470R replace EEE-1CA470WR directly? A: EEE-FN1E470R is electrically compatible as a substitute with identical capacitance and tolerance. However, it has a higher voltage rating (25 V vs. 16 V) and taller height (6.10 mm vs. 5.50 mm). PCB layout verification is required to confirm the increased height does not create clearance conflicts. The higher voltage rating provides design margin without performance degradation.

Q: What is the difference between EEE-FPC470UAR and EEE-HBC470UAR? A: Both parts share 47 µF capacitance, 16 V rating, and 2000-hour lifetime at 105°C. EEE-FPC470UAR has a height of 5.80 mm with Cut Tape packaging, while EEE-HBC470UAR has identical height but Tape & Reel packaging. Selection depends on procurement and assembly requirements. Electrical performance is equivalent.

Q: Why is EEE-1CA470WR marked "Not For New Designs"? A: This designation indicates the part is in mature production phase with limited future availability. Active alternatives such as EEE-1CA470WAR, EEE-HAC470WAR, or EEE-HBC470UAR should be used for new product development to ensure long-term supply continuity.

Q: Are Nichicon UCL1C470MCL6GS and Rubycon 16SEV47M5X5.5 suitable for automotive applications? A: UCL1C470MCL6GS is rated for general purpose applications without AEC-Q200 automotive certification. 16SEV47M5X5.5 carries AEC-Q200 rating and automotive qualification but is in Last Time Buy status. For automotive designs requiring AEC-Q200 compliance, Panasonic parts with active status are preferred.

Q: What footprint considerations apply when substituting with EEE-1CA470AP or EEE-1CA470SP? A: Both parts have larger diameter (6.30 mm vs. 5.00 mm) and different land size (6.60 mm × 6.60 mm vs. 5.30 mm × 5.30 mm). These are not direct footprint replacements and require PCB redesign. They are suitable only when layout modifications are feasible.

Q: Can I use EEE-FN1E470R in a 16 V circuit application? A: Yes. EEE-FN1E470R has a 25 V rating, which exceeds the 16 V requirement. Higher voltage-rated capacitors operate safely in lower voltage applications. This substitution is valid and provides additional voltage margin for circuit protection.
