Parameter Comparison

Engineering Selection Recommendations

EEE-FPA122UAP (Panasonic FP Series)

This substitute provides a 10 V rated alternative with 80 mOhm ESR at 100 kHz, representing a 50% reduction in equivalent series resistance compared to the original part. The component carries AEC-Q200 automotive qualification and maintains identical footprint compatibility. Height is 0.402" (10.20mm), which is 0.011" lower than the original, ensuring mechanical clearance in standard PCB layouts. Selection is appropriate for applications requiring improved thermal performance and automotive-grade reliability.

EEE-FT1C122UP (Panasonic FT Series)

This substitute offers the highest voltage rating at 16 V with the lowest ESR specification of 60 mOhm at 100 kHz. The component is qualified for both automotive applications and high-temperature reflow processes, carrying AEC-Q200 certification. Height matches the original at 0.413" (10.50mm). Ripple current handling is substantially increased to 1.19 A at 100 kHz. Selection is appropriate for designs requiring maximum voltage margin, lowest impedance, or enhanced thermal cycling capability.

UCL1A122MNL1GS (Nichicon UCL Series)

This substitute provides a 10 V rated option with 80 mOhm impedance and the most compact height at 0.394" (10.00mm). The component is rated for general-purpose applications without automotive certification. Ripple current specifications are 425 mA at 120 Hz and 850 mA at 100 kHz. Selection is appropriate for space-constrained applications where voltage margin of 10 V is acceptable and general-purpose reliability is sufficient.

All substitute parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard manufacturing processes and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can the EEE-FPA122UAP be used as a direct replacement for the 865080157015?

A: Yes. Both components share identical capacitance (1200 µF), tolerance (±20%), case diameter (10.00mm), land size (10.30mm x 10.30mm), operating temperature range (-55°C to 105°C), and lifetime rating (2000 Hrs @ 105°C). The EEE-FPA122UAP provides higher voltage rating (10 V vs. 6.3 V) and lower ESR (80 mOhm vs. 160 mOhm), making it functionally compatible for any circuit designed for the original part.

Q: What is the primary advantage of the EEE-FT1C122UP over the original part?

A: The EEE-FT1C122UP offers three key advantages: highest voltage rating (16 V), lowest ESR (60 mOhm at 100 kHz), and highest ripple current capacity (1.19 A at 100 kHz). These characteristics reduce heat generation and extend component life in high-ripple-current applications. AEC-Q200 certification provides automotive-grade reliability.

Q: Are there height differences that affect PCB layout?

A: Yes. The EEE-FPA122UAP has a height of 0.402" (10.20mm), which is 0.011" shorter than the original 0.413" (10.50mm). The UCL1A122MNL1GS is the most compact at 0.394" (10.00mm). The EEE-FT1C122UP matches the original height at 0.413" (10.50mm). All heights remain within standard SMD clearance specifications for typical PCB designs.

Q: Which substitute is best for automotive applications?

A: Both the EEE-FPA122UAP and EEE-FT1C122UP carry AEC-Q200 certification, qualifying them for automotive use. The EEE-FT1C122UP provides additional qualification for high-temperature reflow processes. The UCL1A122MNL1GS is rated for general-purpose applications only and does not carry automotive certification.

Q: How do ESR values affect component selection?

A: Lower ESR reduces heat dissipation and improves high-frequency performance. The original part has 160 mOhm ESR. The EEE-FPA122UAP and UCL1A122MNL1GS both provide 80 mOhm ESR (50% reduction). The EEE-FT1C122UP provides the lowest ESR at 60 mOhm (62.5% reduction). Selection depends on thermal budget and ripple current requirements of the specific application.

Q: Are all substitute parts available in the same packaging format?

A: Yes. All substitute parts are supplied in Tape & Reel (TR) packaging with identical surface-mount land size (0.406" L x 0.406" W / 10.30mm x 10.30mm), ensuring compatibility with standard pick-and-place assembly equipment and reflow processes.

Q: What is the significance of AEC-Q200 certification?

A: AEC-Q200 is an automotive electronics qualification standard that establishes reliability requirements for passive components in automotive applications. Components carrying this certification have undergone extended testing for temperature cycling, vibration, and thermal shock. The EEE-FPA122UAP and EEE-FT1C122UP meet this standard; the original 865080157015 and UCL1A122MNL1GS do not.
