Substitute Part Grouping Explanation

Substitution eligibility for the UCH1V331MCL1GS is determined by strict equivalence across the following critical parameters:

Capacitance value must be 330 µF with tolerance of ±20%. Voltage rating must be 35 V or higher. ESR must be 150 mOhm @ 100 kHz. Operating temperature range must encompass -40°C ~ 125°C. Polarization must be polar. Package and mounting type must be surface mount radial can with identical land size dimensions of 0.406" L x 0.406" W (10.30 mm x 10.30 mm). Physical dimensions (diameter and height) must be compatible with the PCB layout constraints. RoHS3 compliance and AEC-Q200 automotive qualification are required for equivalent substitution in automotive applications.

The EEE-TC1V331UP from Panasonic Electronic Components meets all substitution criteria and is classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the UCH1V331MCL1GS and EEE-TC1V331UP are active production parts with AEC-Q200 automotive qualification and ROHS3 compliance. The EEE-TC1V331UP offers extended lifetime rating of 3000 hours at 125°C compared to 2000 hours for the UCH1V331MCL1GS, along with higher ripple current ratings at both low and high frequencies. The height difference of 0.012" (0.30 mm) between the two parts is within typical PCB layout tolerances for surface mount applications. Selection between these parts should be based on application-specific requirements for thermal endurance and ripple current handling capacity, with both parts meeting the core electrical and mechanical substitution criteria.

Frequently Asked Questions (FAQ)

Q: Can the EEE-TC1V331UP be used as a direct replacement for the UCH1V331MCL1GS?

A: Yes. Both parts share identical capacitance (330 µF), voltage rating (35 V), ESR (150 mOhm @ 100 kHz), operating temperature range (-40°C ~ 125°C), polarization, package type (surface mount radial can), and land size dimensions (0.406" L x 0.406" W). Both are AEC-Q200 qualified and ROHS3 compliant.

Q: What is the significance of the height difference between these parts?

A: The UCH1V331MCL1GS has a maximum seated height of 0.425" (10.80 mm), while the EEE-TC1V331UP is 0.413" (10.50 mm). This 0.012" (0.30 mm) difference is within standard PCB layout tolerances for surface mount components and does not affect functional interchangeability.

Q: Are there differences in ripple current ratings?

A: Yes. The EEE-TC1V331UP has higher ripple current ratings: 487.5 mA @ 120 Hz and 750 mA @ 100 kHz, compared to 250 mA @ 120 Hz and 500 mA @ 100 kHz for the UCH1V331MCL1GS. Applications requiring higher ripple current handling should specify the Panasonic part.

Q: What does the lifetime rating difference mean?

A: The EEE-TC1V331UP is rated for 3000 hours at 125°C, while the UCH1V331MCL1GS is rated for 2000 hours at 125°C. This indicates the Panasonic part has extended thermal endurance. Applications in high-temperature environments may benefit from the longer lifetime rating.

Q: Are both parts suitable for automotive applications?

A: Yes. Both parts carry AEC-Q200 automotive qualification and are suitable for automotive applications. The EEE-TC1V331UP additionally lists high-temperature reflow as an application.
