Engineering Selection Recommendations

Direct Replacement (Same Voltage Rating - 16 V):

EEE-TP1C471AP and EEE-HB1C471AP are direct mechanical and electrical replacements for EEE-1CA471AP. Both maintain the 16 V rating, 470 µF capacitance, and identical land pattern. EEE-TP1C471AP is recommended as the primary replacement due to active product status and extended thermal performance (3000 hours at 125°C versus 2000 hours at 85°C for the original). EEE-HB1C471AP provides equivalent performance with active status and ROHS3 compliance.

Voltage-Upgraded Substitutes (25 V Rating):

EEE-FK1E471AP, EEE-FK1E471P, and EEE-FP1E471AP provide higher voltage ratings (25 V) while maintaining 470 µF capacitance and compatible footprints. These are suitable for applications where circuit voltage margins can accommodate the higher rating. EEE-FK1E471AP and EEE-FP1E471AP are active products with ROHS3 compliance. EEE-FP1E471AP offers superior ripple current handling (1.19 A @ 100 kHz) and lower ESR (60 mOhm @ 100 kHz).

Higher Voltage Substitutes (35 V Rating):

EEE-FN1V471UP provides maximum voltage margin at 35 V rating with active product status. This part is suitable for applications requiring enhanced overvoltage protection or where circuit design permits higher voltage components.

Obsolescence Transition:

EEE-1EA471P and EEE-FK1V471SP are classified as "Not For New Designs" and should not be selected for new applications despite active inventory. These parts are suitable only for field service and legacy production support.

Frequently Asked Questions (FAQ)

Q: Can EEE-FK1E471AP replace EEE-1CA471AP directly in existing designs?

A: Yes. Both parts share identical 470 µF capacitance, compatible 16 V circuit voltage requirements, matching footprint (0.406" x 0.406" land size), and AEC-Q200 automotive qualification. The 25 V rating of EEE-FK1E471AP provides additional voltage margin. Height difference (10.50 mm versus 10.20 mm) must be verified against PCB clearance constraints.

Q: What is the difference between EEE-FK1E471GP and EEE-FK1E471P?

A: Both are 470 µF, 25 V parts with identical footprints and active status. EEE-FK1E471GP provides extended lifetime (5000 hours at 105°C) compared to EEE-FK1E471P (2000 hours at 105°C). Selection depends on application lifetime requirements and thermal environment.

Q: Is EEE-FP1E471AP compatible with the original EEE-1CA471AP?

A: Yes. EEE-FP1E471AP maintains 470 µF capacitance, compatible 25 V rating, identical land pattern, and matching height (10.20 mm). It offers superior electrical performance with lower ESR (60 mOhm @ 100 kHz) and higher ripple current capability (1.19 A @ 100 kHz). Packaging differs (Cut Tape & Digi-Reel versus Tape & Reel), which may affect procurement and assembly processes.

Q: Can higher voltage-rated parts (25 V or 35 V) be used in circuits designed for 16 V?

A: Yes. Higher voltage ratings are electrically compatible with lower voltage circuit requirements. The capacitor will operate safely at voltages below its rated maximum. Circuit design must accommodate any physical height differences and verify PCB layout clearances.

Q: Why should EEE-1EA471P and EEE-FK1V471SP be avoided for new designs?

A: Both parts carry "Not For New Designs" status, indicating Panasonic has transitioned these products to obsolescence. While suitable for field service and legacy production support, active alternatives with superior specifications and guaranteed long-term availability should be selected for new applications.

Q: What is the significance of ROHS3 compliance versus RoHS compliance?

A: ROHS3 represents the current RoHS Directive 2011/65/EU standard with updated substance restrictions. Parts with ROHS3 compliance meet current regulatory requirements and are preferred for new designs. Original RoHS Compliant parts (EEE-1CA471AP, EEE-1EA471P) meet earlier standards and are acceptable for legacy applications.

Q: Are all substitute parts qualified to AEC-Q200 automotive standard?

A: Yes. All parts listed maintain AEC-Q200 qualification, ensuring suitability for automotive applications with equivalent reliability and quality standards.
