Engineering Selection Recommendations

Direct Equivalent (Recommended Primary Substitute):

EEE-FP1A221AP is a direct equivalent to EEE-FP1A221AL. Both parts share identical electrical specifications including 180 mOhm ESR at 100 kHz and 500 mA ripple current at 100 kHz. The case height of EEE-FP1A221AP is 6.20 mm (maximum), which is 0.30 mm shorter than the main part. Both maintain AEC-Q200 qualification, RoHS3 compliance, and 2000-hour lifetime at 105°C. This substitute is suitable for applications where the reduced height provides design advantages without compromising electrical performance.

EEE-FP1A221AV is functionally equivalent to EEE-FP1A221AL with identical electrical and mechanical specifications. This part includes anti-vibration construction, which provides additional mechanical robustness for automotive environments subject to vibration stress. All electrical parameters, case dimensions, and compliance certifications are identical to the main part.

Parametric Equivalents (Secondary Substitutes):

EEE-FK1A221P is a Panasonic FK series alternative with matching core specifications. This part maintains 220 µF capacitance, 10 V rating, 2000-hour lifetime, and AEC-Q200 qualification. The ripple current ratings are lower (225 mA @ 120 Hz and 300 mA @ 100 kHz) compared to the main part. Impedance is specified at 260 mOhms. This substitute is suitable for applications where lower ripple current handling is acceptable.

UCD1A221MCL6GS is a Nichicon UCD series alternative manufactured by a different supplier. This part maintains all core electrical specifications including 220 µF capacitance, 10 V rating, 2000-hour lifetime, and AEC-Q200 qualification. Ripple current ratings are lower (150 mA @ 120 Hz and 300 mA @ 100 kHz). Impedance is specified at 260 mOhms. REACH status is listed as affected, requiring verification for applications subject to REACH compliance requirements. This substitute provides supply chain diversification from an alternative qualified manufacturer.

All substitute parts maintain active product status and are available in production quantities.

Frequently Asked Questions (FAQ)

A: No. EEE-FK1A221P has lower ripple current ratings (225 mA @ 120 Hz and 300 mA @ 100 kHz) compared to EEE-FP1A221AL (325 mA @ 120 Hz and 500 mA @ 100 kHz). This substitute is suitable only for applications where ripple current requirements do not exceed the FK series specifications.

Q: Is UCD1A221MCL6GS suitable for REACH-regulated applications?

A: UCD1A221MCL6GS is listed as REACH Affected, whereas EEE-FP1A221AL is REACH Unaffected. Applications subject to REACH compliance requirements must verify the specific REACH status and documentation for UCD1A221MCL6GS before selection.

Q: Do all substitute parts fit the same PCB footprint as EEE-FP1A221AL?

A: All substitute parts share identical surface mount land size (8.30 mm x 8.30 mm) and case diameter (8.00 mm). Case height varies slightly: EEE-FP1A221AP is 6.20 mm maximum, while EEE-FP1A221AL, EEE-FK1A221P, EEE-FP1A221AV, and UCD1A221MCL6GS are 6.50 mm maximum. These height differences are within standard surface mount assembly tolerances and do not affect PCB footprint compatibility.

Q: Are all substitute parts qualified for automotive applications?

A: Yes. All substitute parts carry AEC-Q200 qualification and are rated for automotive applications with operating temperature range -55°C to 105°C and 2000-hour lifetime at 105°C.

Q: What is the difference in ESR specifications between substitute parts?

A: EEE-FP1A221AL, EEE-FP1A221AP, and EEE-FP1A221AV specify ESR at 180 mOhm @ 100 kHz. EEE-FK1A221P and UCD1A221MCL6GS do not specify ESR but provide impedance at 260 mOhms. Applications requiring specific ESR performance should use parts with explicit ESR specifications.
