• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)
• Mounting type: Through Hole (exact match required)
• Package type: Radial, Can (exact match required)
• Lead spacing: 0.197" (5.00mm) (exact match required)
• Physical dimensions: 0.394" Dia × 0.571" Height (exact match required)
• Operating temperature range: -40°C ~ 125°C (exact match required)
• Lifetime rating: 5000 Hrs @ 125°C (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)

Only parts meeting all specified parameters qualify as direct substitutes. No deviations in electrical or mechanical characteristics are permitted for circuit compatibility.

Parameter Comparison

Engineering Selection Recommendations

The UBT1C331MPD8 maintains active product status with full ROHS3 compliance and REACH compliance certification, supporting long-term procurement and design continuity. When selecting substitute components, priority must be given to parts with identical active product status and equivalent compliance certifications. The automotive application rating and 5000-hour lifetime specification at 125°C establish this part as suitable for demanding thermal and reliability environments. Substitute parts must maintain these compliance and reliability attributes to ensure equivalent performance in end-use applications.

Frequently Asked Questions (FAQ)

Q: What determines if a part can substitute for the UBT1C331MPD8?

A: A substitute part must match all electrical specifications (330 µF capacitance, 16 V rating, ±20% tolerance), mechanical dimensions (0.394" diameter, 0.571" height, 5.00mm lead spacing), thermal performance (5000 Hrs @ 125°C), and compliance certifications (ROHS3, REACH). Any deviation in these parameters disqualifies the part as a direct substitute.

Q: Can I use a capacitor with higher voltage rating as a substitute?

A: No. The rated voltage must be exactly 16 V. Using a higher voltage-rated capacitor changes the physical dimensions, lead spacing, and package characteristics, making it incompatible with the circuit board layout and mounting requirements.

Q: Are there any substitutes available for the UBT1C331MPD8?

A: Based on the provided specifications, the UBT1C331MPD8 is the qualified part for this application. No alternative part numbers have been provided in the substitute list that meet all required parameters.

Q: What is the significance of the 5000-hour lifetime rating?

A: The 5000-hour lifetime at 125°C indicates the capacitor's expected operational duration under maximum temperature stress. This specification is critical for automotive applications and must be matched in any substitute part to ensure equivalent reliability and service life.

Q: Does the ±20% tolerance affect substitution?

A: Yes. The tolerance specification is a critical electrical parameter. Substitute parts must have identical ±20% tolerance to maintain circuit performance and design margin compliance.
