Engineering Selection Recommendations

For Direct Replacement (10 V Rating, Active Status):

EEE-TC1A471P, EEE-TG1A471UP, EEE-TK1A471UP, and EEE-TP1A471AP are active production alternatives with identical 470 µF, 10 V specifications. All are ROHS3 compliant and AEC-Q200 qualified. EEE-TC1A471P and EEE-TP1A471AP support extended temperature operation to 125°C, providing thermal margin beyond the original part's 85°C limit. EEE-TG1A471UP and EEE-TK1A471UP maintain the original 10.20mm height, matching the EEE-1AA471AP footprint exactly.

For Voltage-Upgraded Replacement (25 V Rating, Active Status):

EEE-FK1E471AP, EEE-FK1E471P, and EEE-FK1E471GP provide 25 V rated alternatives with extended operating temperature to 105°C. These parts accommodate higher voltage stress margins and are suitable for designs requiring improved reliability. EEE-FK1E471GP offers the longest lifetime rating at 5000 hours @ 105°C. All FK series parts are 0.413" (10.50mm) in height; PCB layout must accommodate this 0.011" increase.

For Intermediate Voltage Upgrade (16 V Rating, Active Status):

EEE-TC1C471P provides a 16 V rated alternative with 3000 hours @ 125°C lifetime and extended temperature range to 125°C. This part bridges voltage and thermal performance between the original 10 V specification and the 25 V FK series options.

Compliance Considerations:

All recommended active substitutes maintain AEC-Q200 automotive qualification and ROHS3 compliance. The original EEE-1AA471AP carries RoHS Compliant status (not ROHS3); newer designs should transition to ROHS3 qualified parts for regulatory alignment.

Frequently Asked Questions (FAQ)

Q: Can EEE-FK1E471AP replace EEE-1AA471AP directly on the PCB?

A: Electrical substitution is valid; the 25 V rating is backward compatible with 10 V circuit requirements. Physical substitution requires verification of PCB clearance. EEE-FK1E471AP is 0.413" (10.50mm) tall versus the original 0.402" (10.20mm). If PCB height constraints are tight, EEE-TC1A471P, EEE-TG1A471UP, or EEE-TP1A471AP maintain the original height while providing active product status.

Q: What is the difference between EEE-FK1E471AP and EEE-FK1E471GP?

A: Both are 470 µF, 25 V Panasonic FK series parts with identical physical dimensions and electrical ratings. EEE-FK1E471GP is rated for 5000 hours @ 105°C, while EEE-FK1E471AP is rated for 2000 hours @ 105°C. Selection depends on application lifetime requirements.

Q: Why are some substitute parts rated to 125°C when the original is 85°C?

A: Extended temperature rating indicates improved thermal stability and longer operational life at elevated temperatures. Parts such as EEE-TC1A471P and EEE-TP1A471AP maintain the original 10 V voltage rating while supporting higher ambient or internal circuit temperatures, providing design margin for thermal stress.

Q: Is the land size identical across all substitute parts?

A: Yes. All substitute parts listed maintain the 0.406" L x 0.406" W (10.30mm x 10.30mm) surface mount land size, ensuring PCB footprint compatibility. Height variation (0.402" to 0.413") does not affect land pattern but may affect component clearance in confined spaces.

Q: Are all substitute parts AEC-Q200 qualified?

A: EEE-TC1A471P, EEE-TG1A471UP, EEE-TP1A471AP, and all EEE-FK series parts carry AEC-Q200 automotive qualification. EEE-TK1A471UP does not list AEC-Q200 rating and is designated for general purpose applications. For automotive designs, select from AEC-Q200 qualified alternatives.

Q: What is the significance of the part number suffix (AP, P, GP, UP)?

A: Suffixes denote packaging and lead configuration variants within Panasonic's naming convention. All listed parts use Tape & Reel (TR) packaging. Suffix differences reflect internal manufacturing or specification variations; electrical and physical parameters remain consistent within each series.
