EEE-FT1A221AV Equivalent & Substitute Parts

Part Overview

The EEE-FT1A221AV is a 220 µF, 10 V aluminum electrolytic capacitor in surface mount radial can package manufactured by Panasonic Electronic Components. This component is rated for automotive applications and high temperature reflow processes, with AEC-Q200 qualification and a 2000-hour lifetime at 105°C. The part is currently in active production status. Substitute parts may be required due to inventory constraints, design revisions, or supply chain considerations while maintaining equivalent electrical and mechanical performance within specified parameters.

Substitute Part Grouping Explanation

Substitution eligibility for the EEE-FT1A221AV is determined by strict equivalence across the following parameters:

• Capacitance value: 220 µF (exact match required)
• Voltage rating: 10 V (exact match required)
• Tolerance: ±20% (exact match required)
• Package type: Radial, Can - SMD (exact match required)
• Physical dimensions: 0.248" Dia (6.30mm), Height 0.252" (6.40mm) (exact match required)
• Surface mount land size: 0.260" L x 0.260" W (6.60mm x 6.60mm) (exact match required)
• Operating temperature range: -55°C to 105°C (exact match required)
• Lifetime rating: 2000 Hrs @ 105°C (exact match required)
• Polarization: Polar (exact match required)
• Compliance certifications: AEC-Q200, ROHS3 (exact match required)

The EEE-FK1A221SV meets all substitution criteria. Variations in ESR (Equivalent Series Resistance) and ripple current ratings do not disqualify substitution when all primary electrical and mechanical parameters are equivalent.

Parameter Comparison

Engineering Selection Recommendations

The EEE-FK1A221SV is a direct parametric equivalent to the EEE-FT1A221AV. Both parts share identical electrical specifications (220 µF, 10 V, ±20%), mechanical dimensions, surface mount land pattern, operating temperature range, and lifetime rating. Both components carry AEC-Q200 automotive qualification and ROHS3 compliance.

The primary distinction is product status: the EEE-FT1A221AV is in active production, while the EEE-FK1A221SV is designated "Not For New Designs." For new design implementations, the EEE-FT1A221AV is the preferred selection. The EEE-FK1A221SV remains suitable for replacement, repair, or legacy system applications where the substitute part is already qualified in the design.

Frequently Asked Questions (FAQ)

Q: Can the EEE-FK1A221SV be used as a direct replacement for the EEE-FT1A221AV in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent across all critical parameters: capacitance, voltage rating, tolerance, package type, physical dimensions, land size, operating temperature range, and lifetime rating. Both carry AEC-Q200 qualification and ROHS3 compliance.

Q: Why does the EEE-FK1A221SV have higher ESR and lower ripple current ratings?

A: ESR and ripple current are secondary performance characteristics that vary between product series. The EEE-FK1A221SV (FKS series) exhibits different electrical behavior than the EEE-FT1A221AV (FT series), though both meet the primary functional requirements of 220 µF capacitance at 10 V with 2000-hour lifetime at 105°C.

Q: Is the EEE-FK1A221SV suitable for new product designs?

A: The EEE-FK1A221SV carries a "Not For New Designs" status. For new designs, use the EEE-FT1A221AV, which is in active production. The substitute part is appropriate for legacy system support and field replacements.

Q: Are the physical dimensions and land patterns identical?

A: Yes. Both parts have identical dimensions (0.248" Dia / 6.30mm, Height 0.252" / 6.40mm) and surface mount land size (0.260" L x 0.260" W / 6.60mm x 6.60mm). No PCB layout modifications are required when substituting between these parts.

Q: Do both parts meet automotive standards?

A: Yes. Both the EEE-FT1A221AV and EEE-FK1A221SV are AEC-Q200 qualified for automotive applications and support high temperature reflow processes.
