Substitute Part Grouping Explanation

Substitution eligibility for the EEE-1CA221XAP is determined by the following core parameters: capacitance value (220 µF), voltage rating (16 V or higher), tolerance (±20%), physical footprint compatibility (0.260" L x 0.260" W land size), surface mount mounting type, and AEC-Q200 automotive qualification where applicable.

Substitute parts are grouped into the following categories:

Direct Substitutes (Same Voltage, Active Status): Parts with 16 V rating, 220 µF capacitance, and Active product status. These include EEE-FK1C221XP, EEE-FKC221XAP, and EEE-FN1C221XP. These parts maintain electrical equivalence while offering improved thermal performance (2000 Hrs @ 105°C vs. 2000 Hrs @ 85°C) and extended operating temperature ranges (-55°C to 105°C).

Upgraded Substitutes (Enhanced Performance): EEE-FPC221XAP provides the same 16 V, 220 µF specification with reduced ESR (160 mOhm @ 100 kHz) and higher ripple current capability, maintaining the original physical height of 0.303" (7.70mm).

Higher Voltage Substitutes (Voltage Uprating): EEE-FTE221XAP operates at 25 V with identical 220 µF capacitance, providing voltage margin while maintaining the same footprint and land size. This part is suitable where circuit voltage headroom is beneficial.

Similar Geometry Variants: EEE-1CA221P and EEE-1CA221UAP share the same series designation but feature larger physical dimensions (0.315" Dia, 0.402" Height) and different land sizes (0.327" L x 0.327" W), requiring PCB layout verification before substitution.

Parametric Equivalent (Same Packaging): EEE-1CA221XP matches the original part in all electrical and physical parameters, differing only in packaging format (Cut Tape vs. Tape & Reel).

Cross-Manufacturer Alternatives: 16SEV220M6.3X8 (Rubycon) and 227AXZ016M (Cornell Dubilier) provide equivalent 220 µF, 16 V specifications with compatible footprints and AEC-Q200 or general-purpose ratings.

Engineering Selection Recommendations

For new designs, select from parts with Active product status and ROHS3 compliance. EEE-FPC221XAP is the preferred direct substitute, maintaining the original 0.303" (7.70mm) height while offering Active status, extended temperature range (-55°C to 105°C), and improved thermal performance (2000 Hrs @ 105°C). This part requires no PCB layout modification.

EEE-FKC221XAP and EEE-FK1C221XP provide equivalent electrical performance with Active status but require verification of the increased height (0.315" vs. 0.303") against available PCB clearance. Both parts support high-temperature reflow applications.

EEE-FTE221XAP is suitable where voltage margin is required, offering 25 V rating with identical footprint and land size. This part is recommended for circuits operating near the 16 V limit or where future voltage uprating is anticipated.

For cross-manufacturer alternatives, 16SEV220M6.3X8 (Rubycon) maintains the original thermal specification (2000 Hrs @ 85°C) with Active status and compatible dimensions. 227AXZ016M (Cornell Dubilier) offers extended temperature performance but lacks automotive AEC-Q200 rating, limiting use to general-purpose applications.

EEE-1CA221UAP and EEE-1CA221P are not recommended for new designs due to larger physical dimensions (0.402" height, 0.327" land size) requiring PCB layout changes. EEE-1CA221UAP additionally specifies reduced lifetime (1000 Hrs @ 85°C).

Frequently Asked Questions (FAQ)

Q: Can EEE-FPC221XAP directly replace EEE-1CA221XAP without PCB modification?

A: Yes. EEE-FPC221XAP maintains identical physical dimensions (0.248" Dia, 0.303" Height) and land size (0.260" L x 0.260" W), requiring no PCB layout changes. Both parts use the same surface mount footprint.

Q: What is the difference between EEE-FK1C221XP and EEE-FKC221XAP?

A: Both parts are electrically equivalent (220 µF, 16 V, Active status, 2000 Hrs @ 105°C). The primary difference is packaging format: EEE-FK1C221XP is supplied in Cut Tape & Digi-Reel format, while EEE-FKC221XAP is supplied in Tape & Reel format. Both require verification of the increased height (0.315" vs. original 0.303") against PCB clearance.

Q: Why does EEE-FTE221XAP have a higher voltage rating (25 V vs. 16 V)?

A: EEE-FTE221XAP is a voltage-uprated variant of the same 220 µF capacitance. The 25 V rating provides additional voltage margin and is electrically compatible with 16 V circuits. This part is suitable for applications requiring voltage headroom or future circuit modifications.

Q: Is 227AXZ016M suitable for automotive applications?

A: 227AXZ016M is manufactured by Cornell Dubilier and carries ROHS3 compliance but does not specify AEC-Q200 automotive qualification. This part is rated for general-purpose applications. Use in automotive circuits requires verification against specific design requirements and qualification standards.

Q: What is the impact of increased height in EEE-FK1C221XP and EEE-FKC221XAP?

A: Both parts increase from 0.303" (7.70mm) to 0.315" (8.00mm) in seated height. This 0.012" (0.30mm) increase requires verification against available PCB clearance, component spacing, and enclosure constraints. No land size change occurs; only vertical clearance must be confirmed.

Q: Can EEE-1CA221UAP be used as a substitute?

A: EEE-1CA221UAP is Active status but specifies reduced lifetime (1000 Hrs @ 85°C vs. 2000 Hrs @ 85°C in the original part) and larger physical dimensions (0.402" Height, 0.327" land size). This part requires PCB layout modification and is suitable only where reduced lifetime is acceptable.

Q: What does "Not For New Designs" mean for EEE-1CA221XAP?

A: This designation indicates the part is in mature or end-of-life status and is not recommended for new product development. Active-status alternatives such as EEE-FPC221XAP, EEE-FKC221XAP, or EEE-FK1C221XP should be selected for new designs to ensure long-term supply availability and support.
