Engineering Selection Recommendations

Direct Footprint Replacement (Same PCB Land Pattern):

EEE-FPC470UAR and EEE-HBC470UAR maintain the identical 0.209" x 0.209" (5.30mm x 5.30mm) land pattern as the EEE-HAC470WAR. Both are Active status parts with enhanced lifetime ratings (2000 hours at 105°C). EEE-FPC470UAR offers the additional benefit of higher ripple current capability (240 mA @ 100 kHz versus 66.3 mA @ 10 kHz on the original part) and lower ESR (360 mOhm @ 100 kHz), making it suitable for applications requiring improved thermal performance. EEE-HBC470UAR provides equivalent ripple current performance to the main part while extending operational lifetime.

Larger Footprint Substitutes (0.260" x 0.260" Land Pattern):

EEE-HB1C470AP, EEE-HB1C470P, EEE-HC1C470P, EEE-HA1C470AP, and EEE-HA1C470P accommodate larger PCB land patterns (0.260" x 0.260" / 6.60mm x 6.60mm). These parts are suitable for designs with available board space. EEE-HC1C470P (Active status, 3000 hours @ 105°C) represents the highest reliability tier. EEE-HB series parts (Active status, 2000 hours @ 105°C) provide mid-tier reliability. EEE-FC and legacy EEE-HA variants (Not For New Designs status) are acceptable for sustaining production of existing designs but should not be selected for new development.

Dimensional Constraint Consideration:

EEE-HBC470XAP features increased height (0.303" / 7.70mm) and should only be selected if PCB clearance permits, despite its Active status and 2000-hour lifetime rating.

All substitute parts maintain AEC-Q200 automotive qualification, ROHS3 compliance, and operating temperature range of -40°C to 105°C, ensuring compatibility with the original application requirements.

Frequently Asked Questions (FAQ)

Q: Can EEE-FPC470UAR replace EEE-HAC470WAR directly on the PCB?

A: Yes. Both parts share identical land pattern dimensions (0.209" x 0.209" / 5.30mm x 5.30mm). EEE-FPC470UAR is an Active status part with superior ripple current handling and lower ESR, making it a direct upgrade. The slightly increased height (0.228" versus 0.213") does not affect PCB mounting compatibility.

Q: What is the difference between Active and Not For New Designs status parts?

A: Active status parts are recommended for new designs and are supported for long-term supply. Not For New Designs parts are available for sustaining production of existing products but should not be selected for new development. All parts listed maintain AEC-Q200 qualification and automotive compliance regardless of status.

Q: Can I use a larger footprint part (0.260" x 0.260" land pattern) as a substitute?

A: Larger footprint parts require PCB redesign to accommodate the expanded land pattern. They are not direct drop-in replacements but are suitable alternatives if board layout permits. EEE-HC1C470P (3000 hours @ 105°C) offers the highest reliability tier among larger footprint options.

Q: What does lifetime rating (1000 Hrs, 2000 Hrs, 3000 Hrs @ 105°C) mean for my application?

A: Lifetime rating indicates the expected operational duration at maximum rated temperature (105°C) before capacitance degradation reaches specified limits. Higher ratings provide extended service life. For applications operating below 105°C, actual lifetime extends proportionally. All substitute parts meet or exceed the original 1000-hour specification.

Q: Are all substitute parts AEC-Q200 qualified?

A: Yes. All parts listed in this reference maintain AEC-Q200 automotive qualification, ensuring compliance with automotive reliability and qualification standards.

Q: What is the significance of ESR (Equivalent Series Resistance)?

A: ESR affects ripple current handling capability and thermal performance. EEE-FPC470UAR specifies 360 mOhm @ 100 kHz, enabling superior performance in high-frequency switching applications. The original EEE-HAC470WAR does not specify ESR but supports 66.3 mA ripple current @ 10 kHz.

Q: Can I mix different substitute parts in the same production batch?

A: All listed parts are electrically equivalent (47 µF, 16 V, ±20%, -40°C to 105°C, AEC-Q200). However, PCB land pattern compatibility must be verified. Parts with different footprints (5.00mm versus 6.30mm diameter) require separate PCB designs. Within the same footprint family, substitution is permissible provided design documentation is updated to reflect the change.
