Engineering Selection Recommendations

For Direct Replacement (Same Specifications, Active Status):

EEE-HD1C470AP: Maintains 16 V rating with Active product status and extended lifetime (5000 Hrs @ 105°C). Recommended for new production requiring immediate drop-in compatibility with improved reliability.
EEE-HB1C470AP or EEE-HB1C470P: Active status with 2000 Hrs @ 105°C lifetime and extended operating temperature to 105°C. Suitable for designs requiring higher temperature operation.
EEE-HC1C470P: Active status with 3000 Hrs @ 105°C lifetime, providing intermediate reliability enhancement.

For Voltage Margin Applications:

EEE-FN1V470P: 35 V rating provides design margin for circuits with voltage transients. Active status with extended temperature range (-55°C ~ 105°C) and specified ESR (360 mOhm @ 100kHz).
EEE-FP1E470AP or EEE-FP1V470AP: 25 V or 35 V ratings with superior ESR performance (260 mOhm @ 100kHz), extended temperature range, and higher ripple current capacity.

For Performance Enhancement:

EEE-FP1C470AP: Maintains 16 V rating with significantly improved ESR (260 mOhm @ 100kHz), extended temperature range (-55°C ~ 105°C), and 2.8× higher ripple current capacity (300 mA @ 100 kHz vs. 119 mA).

For Thermal Constrained Applications:

EEE-1CA470WAR: Same series as main part with Active status, but reduced lifetime (1000 Hrs @ 85°C) and lower ripple current. Use only when thermal constraints or cost considerations override reliability requirements.

All substitute parts maintain AEC-Q200 automotive compliance and RoHS/REACH compliance status.

Frequently Asked Questions (FAQ)

Q: Can EEE-FN1V470P (35 V) be used in place of EEE-1CA470SP (16 V)? A: Yes. The 35 V rating is electrically compatible with 16 V circuits and provides additional voltage margin. The capacitance (47 µF) and tolerance (±20%) remain identical. Physical dimensions are compatible with the same PCB land pattern (0.260" × 0.260"). Height increases from 5.50 mm to 6.10 mm; verify clearance in your application.

Q: What is the difference between EEE-FP and EEE-HC series? A: EEE-FP series offers lower ESR (260 mOhm @ 100kHz) and higher ripple current capacity (300 mA @ 100 kHz) with extended temperature range (-55°C ~ 105°C). EEE-HC series provides intermediate lifetime (3000 Hrs @ 105°C) without specified ESR. Select EEE-FP for noise-sensitive or high-ripple-current applications; select EEE-HC for standard reliability upgrades.

Q: Is EEE-1CA470WAR a suitable substitute? A: EEE-1CA470WAR maintains identical physical dimensions and voltage rating but offers reduced lifetime (1000 Hrs @ 85°C vs. 2000 Hrs @ 85°C) and lower ripple current capacity. Use only when the original part's thermal specifications exceed application requirements and cost optimization is prioritized.

Q: Do all substitutes fit the same PCB footprint? A: All substitutes use identical surface mount land size (0.260" L × 0.260" W / 6.60 mm × 6.60 mm). Height varies: EEE-1CA470SP and EEE-1CA470WAR are 5.50 mm; most upgrades are 5.80 mm; EEE-FN1V470P is 6.10 mm. Verify vertical clearance in your PCB assembly.

Q: Which substitute offers the best ESR performance? A: EEE-FP series (EEE-FP1C470AP, EEE-FP1E470AP, EEE-FP1V470AP) specifies 260 mOhm @ 100kHz. EEE-HD1C470AP specifies 4 Ohms. EEE-FN1V470P specifies 360 mOhm @ 100kHz. Select EEE-FP for applications requiring minimal impedance.

Q: Are all parts AEC-Q200 compliant? A: Yes. All listed parts maintain AEC-Q200 automotive qualification and RoHS3 compliance (except the main part, which is RoHS Compliant). All are REACH Unaffected.
