Engineering Selection Recommendations

For Direct Replacement (Same Voltage, Same Case): EEE-1CA101P is the parametric equivalent with identical electrical specifications and case dimensions. Both parts carry RoHS compliance and AEC-Q200 automotive rating. EEE-1CA101P is designated Not For New Designs, matching the status of the original part.

For Active Production (Voltage Upgrade, Enhanced Thermal Performance): EEE-FK1E101AP is the manufacturer-recommended substitute. This part maintains 100 µF capacitance and ±20% tolerance with upgraded 25 V rating. It provides extended operating temperature range (-55°C ~ 105°C) and 2000 Hrs @ 105°C lifetime rating. The case height increases from 0.244" to 0.256", requiring PCB layout verification. ROHS3 compliance and AEC-Q200 certification are maintained. Product status is Active.

For Performance-Critical Applications (Lowest ESR, Highest Ripple Current): EEE-FP1E101AP delivers 180 mOhm ESR @ 100 kHz and 500 mA ripple current @ 100 kHz. Physical dimensions match the original part (0.315" × 0.244"). Extended temperature range and 2000 Hrs @ 105°C rating are provided. Product status is Active with ROHS3 compliance.

For Space-Constrained Designs (Smaller Case): EEE-1CA101WAP and EEE-1CA101WP reduce case size to 0.248" Dia × 0.217" H. These parts are suitable only if PCB layout permits downsizing. Lifetime rating is reduced to 1000 Hrs @ 85°C, and ripple current capability is significantly lower (70 mA @ 120 Hz). EEE-1CA101WAP carries Active status with ROHS3 compliance.

For Cross-Manufacturer Sourcing: AFK107M25E16T-F (Cornell Dubilier Electronics) and 25SEV100M8X6.5 (Rubycon) provide alternative sources with identical electrical specifications. Both carry AEC-Q200 automotive qualification and ROHS3 compliance. AFK107M25E16T-F is Active; 25SEV100M8X6.5 is Last Time Buy status.

Frequently Asked Questions (FAQ)

Q: Can EEE-1EA101UP be used as a direct replacement for EEE-1CA101AP? A: EEE-1EA101UP shares identical case size and land pattern but is rated at 25 V instead of 16 V. The higher voltage rating provides design margin. However, ripple current capability is reduced (91 mA @ 120 Hz versus 200 mA). This part is suitable only if circuit ripple current requirements do not exceed 91 mA @ 120 Hz. Both parts are designated Not For New Designs.

Q: What is the primary difference between EEE-FK1E101AP and EEE-FP1E101AP? A: Both parts provide 100 µF at 25 V with Active product status and extended temperature range. EEE-FP1E101AP offers superior performance with 180 mOhm ESR and 500 mA ripple current @ 100 kHz, compared to EEE-FK1E101AP at 260 mOhm impedance and 300 mA ripple current. EEE-FK1E101AP case height is 0.256"; EEE-FP1E101AP matches the original 0.244" height. Selection depends on ripple current and ESR requirements.

Q: Are the smaller case parts (EEE-1CA101WAP, EEE-1CA101WP) suitable replacements? A: These parts reduce case diameter from 0.315" to 0.248" and height from 0.244" to 0.217". Electrical specifications remain 100 µF at 16 V with ±20% tolerance. However, lifetime rating drops to 1000 Hrs @ 85°C, and ripple current is reduced to 70 mA @ 120 Hz. Substitution is valid only if PCB layout accommodates the smaller footprint and circuit ripple current does not exceed 70 mA @ 120 Hz.

Q: What certifications and compliance standards apply to all substitute parts? A: All substitute parts listed carry AEC-Q200 automotive qualification and RoHS or ROHS3 compliance. Moisture Sensitivity Level is 1 (Unlimited) for all parts. REACH status is Unaffected for all parts. These certifications ensure suitability for automotive applications.

Q: Can EEE-1CA101AP be replaced with a 25 V rated part in a 16 V circuit? A: Yes. A higher voltage rating (25 V) is acceptable in a 16 V circuit. This provides additional voltage margin and design safety. All 25 V substitute options (EEE-1EA101UP, EEE-FK1E101AP, EEE-FP1E101AP, EEE-HBE101UAP, AFK107M25E16T-F, 25SEV100M8X6.5) are electrically compatible with 16 V operation.

Q: What is the impact of case height increase from 0.244" to 0.256"? A: EEE-FK1E101P and EEE-FK1E101AP increase case height by 0.012" (0.30mm). This requires verification that PCB clearance and component placement allow the taller profile. Surface mount land size remains 0.327" L × 0.327" W, so pad layout is unchanged. Height increase does not affect electrical performance.

Q: Why is EEE-1CA101AP designated Not For New Designs? A: This designation indicates the part is in mature production phase with no planned enhancements. For new designs, active production alternatives such as EEE-FK1E101AP, EEE-FP1E101AP, or EEE-HBE101UAP are recommended to ensure long-term availability and access to manufacturing improvements.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel packaging? A: Tape & Reel packaging provides continuous reel format for automated assembly lines. Cut Tape & Digi-Reel packaging offers smaller quantity options with reel availability. Electrical and mechanical specifications are identical; packaging selection depends on production volume and assembly equipment compatibility.
