Engineering Selection Recommendations

For Direct Replacement (Same Specifications): EEE-FC1V221P and EEE-HA1V221P provide identical electrical and physical characteristics to the EEE-FC1V221AP. Both maintain 35 V rating, 220 µF capacitance, and 1000 Hrs @ 105°C lifetime. EEE-HA1V221P offers higher inventory availability (1,000,400 pcs) compared to EEE-FC1V221P (4,560 pcs).

For Active Product Status: EEE-HAH221UAP and EEE-HBH221UAP are classified as Active products with ROHS3 compliance, making them suitable for new designs. EEE-HAH221UAP maintains the same 35 V equivalent performance with 1000 Hrs lifetime, while EEE-HBH221UAP provides extended 2000 Hrs lifetime at 50 V rating.

For Enhanced Reliability: EEE-FK1H221GP and EEE-FK1H221P offer 2000 Hrs @ 105°C lifetime with Active product status and ROHS3 compliance. These parts are rated at 50 V and feature improved impedance characteristics (180 mOhms). Height increases to 0.413" (10.50mm), requiring PCB layout verification.

For Lowest Impedance Performance: EEE-FP1H221AP delivers the lowest impedance at 120 mOhms @ 100kHz with 2000 Hrs lifetime and Active status. This part supports higher ripple current (900 mA @ 100 kHz) and is available in high volume (1,000,400 pcs). Height is 0.413" (10.50mm).

Voltage Upgrade Consideration: When circuit design permits, upgrading from 35 V to 50 V rated parts (EEE-FC1H221P, EEE-HA1H221P, EEE-HAH221UAP, EEE-FK1H221GP, EEE-FK1H221P, EEE-FP1H221AP) provides additional design margin and improved reliability without changing physical footprint compatibility.

Frequently Asked Questions (FAQ)

Q: Can I use a 50 V rated capacitor in place of a 35 V rated capacitor? A: Yes. A higher voltage rating provides additional safety margin and is electrically compatible. The capacitor will function correctly in circuits designed for 35 V operation. Physical dimensions and land size remain identical for most substitutes, ensuring PCB compatibility.

Q: What is the difference between "Not For New Designs" and "Active" product status? A: "Not For New Designs" indicates the part has been superseded and is maintained for existing production support only. "Active" status means the part is current and recommended for new designs. For new applications, select Active status parts such as EEE-FK1H221GP, EEE-FK1H221P, EEE-FP1H221AP, EEE-HAH221UAP, or EEE-HBH221UAP.

Q: Does impedance affect substitution compatibility? A: Impedance affects ripple current handling and thermal performance but does not prevent substitution. Lower impedance (120–180 mOhms) indicates better high-frequency performance. If your circuit requires specific ripple current handling, verify the substitute part's ripple current rating at your operating frequency.

Q: What is the significance of the height difference between 0.402" and 0.413"? A: The 0.413" height applies to FK and FP series parts (EEE-FK1H221GP, EEE-FK1H221P, EEE-FP1H221AP). This 0.011" increase requires verification that PCB clearance and component placement allow the taller profile. Most applications accommodate this variation, but layout review is necessary.

Q: Are all substitute parts AEC-Q200 rated? A: Yes. All listed substitute parts maintain AEC-Q200 automotive qualification, ensuring compliance with automotive reliability standards.

Q: What packaging options are available? A: The main part EEE-FC1V221AP uses Tape & Reel (TR) packaging. Substitute parts are available in Tape & Reel (TR) or Cut Tape (CT) & Digi-Reel® formats. Verify packaging compatibility with your procurement and assembly processes.

Q: Which substitute offers the best long-term reliability? A: EEE-FK1H221GP, EEE-FK1H221P, EEE-HBH221UAP, and EEE-FP1H221AP all provide 2000 Hrs @ 105°C lifetime, double that of the original part. EEE-FP1H221AP additionally offers the lowest impedance (120 mOhms) and highest ripple current capability.
