Engineering Selection Recommendations

For Direct Replacement (Same Thermal Profile): EEE-1VA101UAP is the active-status equivalent within the S series, maintaining identical physical dimensions and thermal operating range. This part is suitable for applications where the original 2000-hour lifetime at 85°C specification is acceptable and active product support is required.

For Enhanced Reliability (Extended Lifetime): EEE-FK1V101AP and EEE-FK1V101GP provide superior lifetime ratings (2000 and 5000 hours respectively at 105°C) while maintaining the 35 V rating and compatible package dimensions. These parts support extended operational life in automotive applications with AEC-Q200 certification and active product status.

For High-Temperature Applications: EEE-TC1V101P, EEE-TG1V101UP, EEE-TK1V101UP, and EEE-TP1V101AP extend the operating temperature range to 125°C with lifetime ratings from 2000 to 3000 hours at that temperature. These are suitable for high-temperature reflow processes and elevated ambient environments. EEE-TC1V101P and EEE-TP1V101AP maintain AEC-Q200 certification.

For Voltage Margin Increase: EEE-FK1H101GP provides 50 V rating with 5000-hour lifetime at 105°C, offering increased transient voltage tolerance while maintaining the same capacitance and compatible package footprint.

Recommended Primary Substitute (MFR Recommended): EEE-FK1V101P combines active product status, AEC-Q200 certification, 2000-hour lifetime at 105°C, and extended temperature range (-55°C ~ 105°C), making it the manufacturer-recommended replacement for new designs transitioning from the EEE-1VA101UP.

Frequently Asked Questions (FAQ)

Q: Can EEE-1VA101UAP be used as a direct drop-in replacement? A: Yes. EEE-1VA101UAP maintains identical capacitance (100 µF), voltage rating (35 V), tolerance (±20%), package dimensions (0.315" Dia, 0.402" height), and mounting type. The primary difference is reduced lifetime (1000 hours vs. 2000 hours at 85°C) and active product status.

Q: What is the difference between the S series (EEE-1VA) and FK series (EEE-FK1V)? A: The FK series provides extended operating temperature range (-55°C ~ 105°C vs. -40°C ~ 85°C) and higher temperature lifetime ratings (105°C vs. 85°C). Physical dimensions are compatible (height increases from 10.20mm to 10.50mm). Both maintain 100 µF, 35 V specifications and AEC-Q200 certification.

Q: Are the higher temperature series (TC, TG, TK, TP) compatible with the original footprint? A: Yes, all substitute parts maintain the 0.315" diameter (8.00mm) and surface mount land size (0.327" L x 0.327" W). Height varies between 0.402" (10.20mm) and 0.413" (10.50mm), which is acceptable for standard SMD reflow processes. Verify PCB clearance for the taller variants.

Q: Which substitute offers the longest operational life? A: EEE-FK1H101GP provides 5000 hours at 105°C. EEE-FK1V101GP also provides 5000 hours at 105°C with 35 V rating. Both are suitable for applications requiring extended service life.

Q: Is AEC-Q200 certification maintained across all substitutes? A: No. EEE-TK1V101UP does not carry AEC-Q200 certification. All other substitutes listed maintain AEC-Q200 compliance. For automotive applications, verify certification requirements before selection.

Q: Can the 50 V rated parts (EEE-FK1H101GP, EEE-1HA101UP) be used in 35 V circuits? A: Yes. Higher voltage-rated capacitors are electrically compatible in lower voltage applications. The 50 V rating provides additional design margin for transient voltage spikes. Physical dimensions remain compatible.

Q: What is the impact of ESR (Equivalent Series Resistance) differences? A: ESR values are provided for high-frequency ripple current performance. EEE-TC1V101P specifies 200 mOhm @ 100 kHz, EEE-TK1V101UP specifies 300 mOhm @ 100 kHz, and FK series parts specify 160 mOhm. Lower ESR reduces heat generation in high-ripple-current applications. Verify ripple current requirements against the specific substitute's rating.

Q: Is the packaging format (Tape & Reel vs. Cut Tape) significant for substitution? A: Packaging format affects supply chain logistics but not electrical or mechanical compatibility. EEE-FK1H101GP is supplied in Cut Tape & Digi-Reel format; all other substitutes use Tape & Reel. Both formats are compatible with standard SMD assembly equipment.
