Tolerance: ±20% (matching tolerance)
Package Type: Radial, Can - SMD (identical form factor)
Physical Dimensions: 0.248" Dia (6.30mm), Height ≤ 0.315" (8.00mm), Land Size 0.260" L x 0.260" W (6.60mm x 6.60mm)
Mounting Type: Surface Mount
Polarization: Polar
Operating Temperature Range: Minimum -40°C ~ 85°C (equal or wider range acceptable)
Lifetime: 2000 Hrs @ 85°C minimum (equal or longer lifetime acceptable)

Substitute parts are grouped into two categories: direct equivalents (matching all parameters) and upgraded alternatives (superior performance characteristics while maintaining mechanical and electrical compatibility).

Engineering Selection Recommendations

For direct replacement of the obsolete ECE-V1AA221XP in existing designs, select from the following based on compliance and availability requirements:

Direct Electrical Equivalents (10 V, 220 µF):

EEE-1AA221XP: Panasonic S-series, RoHS compliant, 42,731 units in stock. Suitable for legacy designs requiring exact electrical match. Product status is "Not For New Designs."
EEE-FK1A221XP: Panasonic FK-series, ROHS3 compliant, active product status. Extended operating temperature range (-55°C ~ 105°C) and improved lifetime (2000 Hrs @ 105°C). Height increases to 8.00mm; verify PCB clearance.
EEE-FPA221XAP: Panasonic FP-series, ROHS3 compliant, active product status. Enhanced ripple current capability (390 mA @ 120 Hz vs. 173 mA). Maintains original height of 7.70mm.

Voltage-Upgraded Alternatives (16 V, 220 µF):

EEE-1CA221XP: Panasonic S-series, RoHS compliant, 20,839 units in stock. Provides voltage margin while maintaining original dimensions. Product status is "Not For New Designs."

Frequently Asked Questions (FAQ)

Q: Can EEE-FK1A221XP replace ECE-V1AA221XP directly on the PCB? A: Electrical substitution is valid. Physical verification is required: EEE-FK1A221XP height is 8.00mm versus ECE-V1AA221XP at 7.70mm. Confirm PCB clearance and solder pad compatibility before assembly.

Q: What is the difference between EEE-1AA221XP and EEE-FK1A221XP? A: Both are 220 µF, 10 V parts. EEE-1AA221XP (S-series) operates -40°C ~ 85°C with 2000 Hrs @ 85°C lifetime and is "Not For New Designs." EEE-FK1A221XP (FK-series) operates -55°C ~ 105°C with 2000 Hrs @ 105°C lifetime, is active status, and offers extended temperature performance. Height differs: 7.70mm vs. 8.00mm.

Q: Is a 16 V rated capacitor suitable for a 10 V circuit? A: Yes. Higher voltage rating provides design margin and does not degrade performance in lower voltage applications. Capacitance, tolerance, and physical dimensions remain equivalent. EEE-1CA221XP and EEE-FK1C221XP are valid 16 V alternatives for 10 V circuits.

Q: What does "Not For New Designs" product status mean? A: This designation indicates the part is in mature/declining production phase. Existing inventory is available, but Panasonic does not recommend these parts for new product development. For new designs, select active status parts such as EEE-FK1A221XP, EEE-FPA221XAP, or EEE-FTE221XAP.

Q: Does packaging format (Tape & Reel vs. Cut Tape) affect electrical performance? A: No. Packaging format affects supply chain logistics and handling only. Electrical and mechanical specifications are identical between packaging options. Select based on production volume and assembly equipment compatibility.

Q: Why does EEE-FPA221XAP have higher ripple current than the original part? A: EEE-FPA221XAP (FP-series) features lower ESR (160 mOhm @ 100 kHz) and improved internal construction, resulting in 390 mA ripple current capacity at 120 Hz versus 173 mA for ECE-V1AA221XP. This represents enhanced performance without electrical incompatibility.

Q: Are all substitute parts AEC-Q200 rated? A: All listed substitute parts carry AEC-Q200 automotive qualification. This certification confirms reliability testing and quality standards suitable for automotive and industrial applications.
