Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the UUQ0J331MCL1GS is determined by strict equivalence across the following critical parameters:

• Capacitance: 330 µF (exact match required)
• Voltage Rating: 6.3 V (exact match required)
• Tolerance: ±20% (exact match required)
• Package / Case: Radial, Can - SMD (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Physical Dimensions: 0.315" Dia (8.00mm) and compatible height (6.20mm to 6.50mm acceptable)
• Surface Mount Land Size: Compatible with 8.30mm x 8.30mm or 8.30mm x 9.50mm footprints
• Polarization: Polar (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

All three substitute parts meet these core substitution criteria. Secondary parameters such as lifetime, ripple current ratings, operating temperature range, and compliance certifications may vary and should be evaluated based on specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are electrically and mechanically compatible with the UUQ0J331MCL1GS based on core substitution parameters. Selection among these alternatives depends on application-specific requirements:

AFK337M06E16T-F (Cornell Dubilier Electronics) provides the highest ripple current capacity (300 mA @ 100 kHz) and extended lifetime (2000 Hrs @ 105°C). This part carries AEC-Q200 automotive qualification and operates across an extended temperature range (-55°C ~ 105°C). The surface mount land size is 8.30mm x 9.50mm, which requires verification against PCB layout constraints. ESR is specified at 260 mOhm @ 100 kHz.

EEE-FK0J331P (Panasonic Electronic Components) matches the original part's surface mount land size (8.30mm x 8.30mm) and offers extended lifetime (2000 Hrs @ 105°C) with AEC-Q200 certification. Operating temperature range extends to -55°C. Ripple current capacity is 300 mA @ 100 kHz with 260 mOhms impedance.

EEE-HAJ331UAP (Panasonic Electronic Components) maintains identical physical dimensions and height (0.244" / 6.20mm) to the original part, with matching surface mount land size (8.30mm x 8.30mm). Lifetime matches the original specification (1000 Hrs @ 105°C). This part carries AEC-Q200 certification and operates across the same temperature range as the original (-40°C ~ 105°C). Ripple current capacity is 180 mA @ 120 Hz and 306 mA @ 10 kHz.

Frequently Asked Questions (FAQ)

Q: Can I substitute the UUQ0J331MCL1GS with any of these parts without PCB modification?

A: EEE-FK0J331P and EEE-HAJ331UAP require no PCB modification, as they maintain identical surface mount land sizes (8.30mm x 9.50mm). AFK337M06E16T-F has a land size of 8.30mm x 9.50mm and requires verification that the PCB footprint accommodates this dimension.

Q: What is the primary difference between the substitute parts?

A: The main differences are lifetime rating (1000 Hrs vs. 2000 Hrs @ 105°C), ripple current capacity, and operating temperature range. AFK337M06E16T-F and EEE-FK0J331P offer extended lifetime and lower temperature operation (-55°C). EEE-HAJ331UAP maintains the original specifications while providing AEC-Q200 automotive qualification.

Q: Are all substitute parts RoHS3 compliant?

A: Yes, all three substitute parts are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), matching the original part's compliance status.

Q: Which substitute part is best for automotive applications?

A: All three substitute parts carry AEC-Q200 automotive qualification. Selection depends on specific thermal and ripple current requirements. AFK337M06E16T-F and EEE-FK0J331P support extended temperature operation (-55°C ~ 105°C) and higher ripple current capacity (300 mA @ 100 kHz).

Q: Do the substitute parts have the same height?

A: EEE-HAJ331UAP and the original part share identical height (0.244" / 6.20mm). AFK337M06E16T-F and EEE-FK0J331P are slightly taller at 0.256" (6.50mm). Verify clearance in your application before substitution.

Q: What does ESR specification mean for these capacitors?

A: ESR (Equivalent Series Resistance) affects ripple current handling and thermal performance. AFK337M06E16T-F specifies 260 mOhm @ 100 kHz. EEE-FK0J331P specifies 260 mOhms impedance. The original part and EEE-HAJ331UAP do not provide ESR specifications in the available data.
