Substitute Part Grouping Explanation

Substitution of the EEE-1CA220WR is determined by strict equivalence in the following parameters: capacitance (22 µF), voltage rating (16 V), tolerance (±20%), package type (Radial, Can - SMD), case diameter (4.00 mm), land size (4.30 mm x 4.30 mm), and mounting type (Surface Mount). Parts are grouped into the following categories based on product status and performance characteristics:

MFR Recommended Substitutes (Panasonic - Active Status): Parts that maintain the same electrical specifications while offering improved performance metrics such as extended lifetime or lower ESR, with active product status.

Upgrade Substitutes (Panasonic - Active Status): Parts that provide enhanced performance characteristics including extended temperature range, increased lifetime rating, or improved ripple current handling, while maintaining core electrical parameters.

Parametric Equivalents (Panasonic - Active Status): Parts that match the primary electrical and mechanical specifications with active product status, suitable for direct replacement.

Similar Parts (Panasonic - Not For New Designs): Parts with identical electrical specifications but different case dimensions (5.00 mm diameter instead of 4.00 mm), requiring PCB layout verification before substitution.

Direct Substitutes (Alternative Manufacturers): Parts from KEMET and Nichicon that meet the same electrical and mechanical specifications, offering supply chain alternatives while maintaining compatibility.

Engineering Selection Recommendations

For Direct Replacement with Active Product Status: EEE-1CA220WAR is the primary active equivalent from Panasonic, maintaining identical electrical specifications and case dimensions (4.00 mm diameter, 5.50 mm height) with ROHS3 compliance. This part is suitable for direct substitution in existing designs without PCB modification.

For Enhanced Performance Requirements: EEE-FPC220UAR and EEE-HBC220UAR offer extended lifetime (2000 hours at 105°C) and improved ripple current handling compared to the original part. Both maintain the 4.00 mm case diameter and are ROHS3 compliant. EEE-FPC220UAR provides the lowest ESR at 850 mOhm @ 100 kHz.

For Extended Temperature Range Applications: EEE-FN1C220R, EEE-FPC220UAR, EEE-HAC220WAR, EEE-HBC220UAR, and UCL1C220MCL6GS all support operating temperatures from -55°C to 105°C, compared to the original -40°C to 85°C range. These parts are suitable for applications requiring broader thermal performance.

For Supply Chain Alternatives: EDK226M016A9BAA (KEMET) and UCL1C220MCL6GS (Nichicon) provide equivalent electrical and mechanical specifications with active product status and ROHS3 compliance, offering alternative sourcing options while maintaining full compatibility.

For Designs with Space Constraints: EEE-HAC220WAR and EEE-HA1C220WR offer the smallest height at 5.40 mm while maintaining the 4.00 mm case diameter, suitable for applications with limited vertical clearance.

Not Recommended for New Designs: Parts with "Not For New Designs" status (EEE-1CA220WR, EEE-HA1C220WR, EEE-1CA220AR, EEE-1CA220SR) should not be selected for new product development. Existing designs using these parts should transition to active alternatives during the next design revision cycle.

Frequently Asked Questions (FAQ)

Q: Can EEE-1CA220WR be replaced with EEE-1CA220AR or EEE-1CA220SR? A: These parts have identical electrical specifications but differ in case diameter (5.00 mm vs. 4.00 mm) and land size (5.30 mm x 5.30 mm vs. 4.30 mm x 4.30 mm). PCB layout verification is required before substitution. Both parts are marked "Not For New Designs."

Q: What is the primary advantage of EEE-FPC220UAR over the original EEE-1CA220WR? A: EEE-FPC220UAR provides extended lifetime (2000 hours at 105°C vs. 1000 hours at 85°C), lower ESR (850 mOhm @ 100 kHz), higher ripple current capability (160 mA @ 100 kHz vs. 47.6 mA @ 10 kHz), and broader operating temperature range (-55°C to 105°C vs. -40°C to 85°C), while maintaining identical case dimensions and land size.

Q: Are KEMET EDK226M016A9BAA and Nichicon UCL1C220MCL6GS fully compatible with EEE-1CA220WR? A: Both parts match the electrical specifications (22 µF, 16 V, ±20% tolerance) and case dimensions (4.00 mm diameter, 4.30 mm x 4.30 mm land size). EDK226M016A9BAA has a maximum height of 5.65 mm and UCL1C220MCL6GS has 5.80 mm, both within acceptable tolerance for the original 5.50 mm specification. Both are ROHS3 compliant and active products.

Q: Why is EEE-1CA220WR marked "Not For New Designs"? A: This designation indicates the part is in end-of-life status. Active alternatives with improved performance characteristics and extended lifetime ratings are available. New designs should select from active product alternatives such as EEE-1CA220WAR, EEE-FPC220UAR, or EEE-HBC220UAR.

Q: What is the difference between EEE-HAC220WAR and EEE-HA1C220WR? A: Both are from the HA series with identical electrical specifications and 5.40 mm height. EEE-HAC220WAR has active product status and ROHS3 compliance, while EEE-HA1C220WR is marked "Not For New Designs" with RoHS compliance. EEE-HAC220WAR is the recommended choice for new designs.

Q: Can substitutes with different operating temperature ranges be used in designs rated for -40°C to 85°C? A: Yes. Parts with extended temperature ranges (such as -55°C to 105°C) are backward compatible with designs requiring -40°C to 85°C operation. The extended range provides additional design margin and flexibility for future applications.

Q: What packaging format is used for these parts? A: The original part EEE-1CA220WR uses Tape & Reel (TR) packaging. UCL1C220MCL6GS uses Cut Tape (CT) & Digi-Reel® packaging. Verify packaging compatibility with assembly equipment before procurement.
