Engineering Selection Recommendations

Direct Equivalent (Same Voltage, Enhanced Reliability):

EEE-HB1A221AP and EEE-HC1A221P are direct electrical and mechanical equivalents with identical 10 V ratings and 220 µF capacitance. Both parts carry Active product status, eliminating obsolescence risk. EEE-HC1A221P provides the highest reliability with 5000-hour lifetime at 105°C, compared to the original 1000-hour rating. Both are ROHS3 compliant and maintain AEC-Q200 automotive qualification.

Voltage-Upgraded Substitutes (25 V Rating):

EEE-FK1E221AP, EEE-FK1E221GP, and EEE-FK1E221P provide 25 V rated alternatives with 220 µF capacitance. These parts are suitable for circuits where the original 10 V specification allows margin for higher voltage operation. All three carry Active status and ROHS3 compliance. EEE-FK1E221GP offers extended 5000-hour lifetime. Height increases to 0.413" (10.50mm), requiring PCB layout verification.

Voltage-Upgraded Substitutes (35 V Rating):

EEE-FK1V221AP, EEE-FK1V221GP, and EEE-FK1V221P provide 35 V rated alternatives with 220 µF capacitance. These parts accommodate circuits requiring higher voltage margin or operating in elevated voltage environments. All three carry Active status and ROHS3 compliance. EEE-FK1V221GP offers extended 5000-hour lifetime. Height increases to 0.413" (10.50mm), requiring PCB layout verification.

Low-ESR Alternative (25 V Rating):

EEE-FP1E221AP provides a 25 V, 220 µF alternative with specified ESR of 80 mOhm @ 100 kHz and elevated ripple current handling (552.5 mA @ 120 Hz, 850 mA @ 100 kHz). This part maintains the original 0.402" (10.20mm) height and is suitable for applications requiring lower impedance performance. Active status and ROHS3 compliance are confirmed.

Frequently Asked Questions (FAQ)

Q: Can EEE-HB1A221AP or EEE-HC1A221P be used as direct replacements for EEE-HA1A221AP?

A: Yes. Both parts are electrically and mechanically identical with 220 µF capacitance, 10 V rating, ±20% tolerance, and identical case dimensions. The primary differences are extended lifetime ratings (2000 and 5000 hours respectively) and Active product status. No circuit modifications are required.

Q: What is the difference between 10 V, 25 V, and 35 V rated parts?

A: Voltage rating indicates the maximum continuous voltage the capacitor can withstand. A 25 V or 35 V rated capacitor can be used in a 10 V circuit without electrical degradation. Higher voltage ratings provide design margin and may improve reliability in circuits with voltage transients. Physical dimensions increase slightly with higher voltage ratings.

Q: Does the height increase from 0.402" to 0.413" affect PCB compatibility?

A: The 0.011" (0.30mm) height increase must be verified against PCB layout constraints, component clearances, and assembly equipment specifications. Confirm available vertical space before substitution.

Q: Are all substitute parts AEC-Q200 qualified?

A: Yes. All substitute parts listed carry AEC-Q200 automotive qualification, maintaining compliance with automotive reliability standards.

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel packaging?

A: Both are surface mount packaging formats suitable for automated assembly. Tape & Reel is continuous reel format. Cut Tape & Digi-Reel is pre-cut tape format. Selection depends on assembly equipment and procurement requirements. Electrical and mechanical specifications remain identical.

Q: Is EEE-FP1E221AP compatible with the original circuit design?

A: EEE-FP1E221AP is electrically compatible as a 25 V, 220 µF substitute. It maintains the original 0.402" (10.20mm) height for direct PCB fit. The primary difference is lower ESR (80 mOhm @ 100 kHz) and higher ripple current capability, which may improve performance in high-frequency applications. Verify that 25 V rating is acceptable for the circuit.
