Engineering Selection Recommendations

For New Designs: Select EEE-FN1A101UR (Panasonic) as the primary choice. This part carries Active product status and offers enhanced specifications including extended operating temperature range (-55°C to 105°C), doubled lifetime rating (2000 hours at 105°C), and increased ripple current capability. ROHS3 compliance and AEC-Q200 automotive qualification are maintained.

Alternatively, EEE-1AA101WAR (Panasonic) provides identical electrical and mechanical specifications to the EEE-1AA101WR with Active product status and ROHS3 compliance, suitable for direct replacement in existing designs.

For Existing Designs Requiring Continuation: EEE-1AA101AP and EEE-1AA101SP (Panasonic) are functionally equivalent with extended lifetime (2000 hours at 85°C). Both maintain RoHS compliance and AEC-Q200 qualification. Note that these parts have larger case diameters (0.248" vs. 0.197") and require PCB land size adjustment (0.260" x 0.260" vs. 0.209" x 0.209").

For Non-Automotive Applications: Nichicon alternatives UUR1A101MCL1GS, UWJ1A101MCL1GB, and UWX1A101MCL1GB meet electrical and mechanical equivalence but lack AEC-Q200 certification and carry Obsolete product status. These are suitable only for general-purpose applications where automotive qualification is not required.

Footprint Compatibility Consideration: Parts with 0.248" (6.30mm) case diameter (EEE-1AA101AP, EEE-1AA101SP, UUR1A101MCL1GS, UWJ1A101MCL1GB, UWX1A101MCL1GB) require larger PCB land patterns and cannot be used as direct drop-in replacements on boards designed for the 0.197" (5.00mm) diameter parts without PCB modification.

Frequently Asked Questions (FAQ)

Q: Can EEE-1AA101WR be directly replaced with EEE-FN1A101UR? A: Yes. Both parts share identical electrical specifications (100 µF, 10 V, ±20%), operating temperature range (-40°C to 85°C), and footprint (0.197" diameter, 5.30mm x 5.30mm land size). EEE-FN1A101UR offers superior reliability with 2000-hour lifetime at 105°C versus 1000 hours at 85°C for the original part.

Q: What is the difference between EEE-1AA101WR and EEE-1AA101WAR? A: These parts are electrically and mechanically identical. The primary difference is product status: EEE-1AA101WR is "Not For New Designs" while EEE-1AA101WAR is "Active." Both have identical specifications and footprints. EEE-1AA101WAR is the recommended choice for new designs.

Q: Why do EEE-1AA101AP and EEE-1AA101SP have different case sizes? A: Both parts maintain the same electrical specifications and operating temperature range but feature larger case diameters (0.248" vs. 0.197") and correspondingly larger land sizes (0.260" x 0.260" vs. 0.209" x 0.209"). This requires PCB redesign and cannot be used as a direct footprint replacement.

Q: Are Nichicon parts (UUR1A101MCL1GS, UWJ1A101MCL1GB, UWX1A101MCL1GB) suitable for automotive applications? A: No. While these parts meet electrical and mechanical equivalence, they lack AEC-Q200 automotive qualification and carry Obsolete product status. They are suitable only for general-purpose applications.

Q: What does "Not For New Designs" status mean? A: This designation indicates the part has been superseded by newer alternatives in the manufacturer's product line. Existing designs may continue using the part, but new designs should transition to active alternatives such as EEE-FN1A101UR or EEE-1AA101WAR.

Q: Can I use a substitute part with higher ripple current rating? A: Yes. Parts with higher ripple current ratings (such as EEE-FN1A101UR at 160 mA @ 100 kHz) are compatible and provide additional design margin. Lower ripple current ratings are not acceptable as they may not meet circuit requirements.

Q: What is the significance of ROHS3 compliance versus RoHS compliance? A: ROHS3 represents the current RoHS directive implementation with updated substance restrictions. Both RoHS and ROHS3 compliant parts meet environmental requirements; ROHS3 represents the latest standard.
