Engineering Selection Recommendations

For Direct Replacement (10 V Rating):

EEE-FN1A220R is the manufacturer-recommended substitute. It maintains 10 V voltage rating and 22 µF capacitance while offering extended lifetime (2000 Hrs @ 105°C vs. 1000 Hrs @ 85°C) and active product status. Height increases from 5.40 mm to 6.10 mm; verify PCB clearance before selection.

EEE-HAA220WAR provides identical height (5.40 mm) to the original part with active status and ROHS3 compliance. Lifetime extends to 1000 Hrs @ 105°C with expanded operating temperature range (-40°C ~ 105°C).

For Voltage Upgrade (16 V Rating):

EEE-HAC220WAR offers 16 V rating with identical 5.40 mm height, active status, and ROHS3 compliance. Suitable for designs requiring voltage margin without PCB layout modification.

EEE-FPC220UAR provides 16 V rating with extended lifetime (2000 Hrs @ 105°C) and active status. Height increases to 5.80 mm; verify clearance.

EEE-HBC220UAR delivers 16 V rating with maximum lifetime (2000 Hrs @ 105°C) and active status. Height is 5.80 mm.

Compliance Considerations:

All substitute parts maintain AEC-Q200 automotive qualification. Parts with ROHS3 compliance (EEE-FN1A220R, EEE-FP1A220AR, EEE-HAA220WAR, EEE-1CA220WAR, EEE-FPC220UAR, EEE-HAC220WAR, EEE-HBC220UAR) are preferred for new designs. Parts marked "Not For New Designs" are suitable only for legacy design support.

Frequently Asked Questions (FAQ)

Q: Can EEE-1AA220WR be replaced with a 16 V rated part?

A: Yes. A 16 V rated capacitor with identical 22 µF capacitance, ±20% tolerance, and matching package geometry (0.157" diameter, 4.30 mm x 4.30 mm land size) is electrically compatible. The higher voltage rating provides additional safety margin. Verify PCB height clearance, as some 16 V variants are taller.

Q: What is the difference between EEE-FN1A220R and EEE-FP1A220AR?

A: Both are 10 V, 22 µF active substitutes with 2000 Hrs @ 105°C lifetime. EEE-FN1A220R (FN series) has height 6.10 mm and ESR 1.35 Ohm @ 100 kHz. EEE-FP1A220AR (FP series) has height 5.80 mm and ESR 850 mOhm @ 100 kHz. Select based on PCB clearance and ESR requirements.

Q: Is the 0.169" x 0.169" (4.30 mm x 4.30 mm) land size identical across all substitutes?

A: Yes. All listed substitute parts share the same PCB land size. Physical mounting footprint is compatible without layout modification.

Q: Why do some parts have "Not For New Designs" status?

A: Parts with this designation have reached end-of-life and are retained for legacy design support only. For new designs, select parts with "Active" status such as EEE-FN1A220R, EEE-HAA220WAR, EEE-1CA220WAR, EEE-FPC220UAR, EEE-HAC220WAR, or EEE-HBC220UAR.

Q: What is the impact of height differences on PCB design?

A: Original part height is 5.40 mm. EEE-FN1A220R reaches 6.10 mm, and EEE-FP1A220AR, EEE-FPC220UAR, and EEE-HBC220UAR reach 5.80 mm. Verify available vertical clearance in the design before substitution. Horizontal footprint remains unchanged.

Q: Are all substitute parts AEC-Q200 qualified?

A: Yes. All listed substitute parts carry AEC-Q200 automotive qualification, meeting the same reliability and qualification standards as the original part.
