Ratings: AEC-Q200
Applications: Automotive

Flexible Parameters (allowing substitution):

Voltage Rating: 10 V or higher (higher voltage ratings provide backward compatibility)
Operating Temperature Range: Must encompass or exceed -40°C ~ 85°C

Engineering Selection Recommendations

For New Designs: Select from parts with Active product status. EEE-HAA470WAR and EEE-HAC470WAR offer the same 10 V and 16 V ratings respectively with ROHS3 compliance and active lifecycle support. For applications requiring extended thermal performance, EEE-FPC470UAR (16 V, 2000 Hrs @ 105°C) or EEE-HBC470UAR (16 V, 2000 Hrs @ 105°C) provide enhanced reliability margins.

For Legacy System Support: The EEE-1AA470WR remains available with 10,681 pieces in stock. Direct mechanical and electrical equivalents include EEE-HA1A470WR and EEE-1AA470WAR, both maintaining identical footprint and electrical characteristics while offering improved compliance status.

Voltage Rating Considerations: Higher voltage-rated substitutes (16 V or 25 V) are electrically compatible with 10 V circuit requirements and provide additional safety margin. EEE-1CA470WAR and EEE-1CA470WR (16 V) maintain identical thermal and mechanical specifications. EEE-FN1E470R (25 V) offers superior thermal performance (2000 Hrs @ 105°C) with extended operating temperature range (-55°C ~ 105°C) but requires PCB height clearance verification due to 0.240" maximum seated height.

Compliance Path: Transition from RoHS Compliant to ROHS3 Compliant status using EEE-1AA470WAR, EEE-HAA470WAR, or EEE-HAC470WAR without electrical or mechanical redesign.

Frequently Asked Questions (FAQ)

Q: Can I use a higher voltage-rated capacitor as a substitute? A: Yes. A 16 V or 25 V rated capacitor functions correctly in a 10 V circuit. Higher voltage ratings provide additional safety margin and do not affect circuit operation when all other parameters (capacitance, tolerance, package, footprint) remain identical.

Q: What is the difference between "Not For New Designs" and "Active" status? A: "Not For New Designs" indicates the manufacturer no longer recommends this part for new product development but continues to support existing applications. "Active" status confirms the part is recommended for both new designs and ongoing production. For new designs, select Active status parts.

Q: Are there height restrictions when substituting? A: Yes. The original EEE-1AA470WR has a maximum seated height of 0.213" (5.40mm). Substitutes with heights up to 0.228" (5.80mm) such as EEE-FPC470UAR and EEE-HBC470UAR require verification of PCB assembly clearance. Confirm available vertical space before selection.

Q: What does MSL 1 (Unlimited) mean? A: Moisture Sensitivity Level 1 indicates the component has unlimited shelf life without special moisture control measures. No desiccant storage or baking procedures are required prior to assembly.

Q: Can I substitute EEE-1AA470WR with EEE-FN1E470R? A: Yes, electrically and mechanically. EEE-FN1E470R provides superior thermal performance (2000 Hrs @ 105°C versus 1000 Hrs @ 85°C) and extended operating temperature range (-55°C ~ 105°C). However, verify PCB height clearance as maximum seated height increases from 0.213" to 0.240".

Q: Are all substitutes AEC-Q200 qualified? A: Yes. All listed substitute parts maintain AEC-Q200 automotive qualification and are suitable for automotive applications.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel packaging? A: Tape & Reel (TR) is standard for high-volume automated assembly. Cut Tape (CT) & Digi-Reel is used for lower-volume orders or mixed component kits. Electrical and mechanical specifications remain identical; packaging affects procurement and handling only.
