Substitute Part Grouping Explanation

Substitution eligibility for the UBW1A331MPD1TD is determined by the following criteria:

Mandatory Matching Parameters:

• Capacitance: 330 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)
• Package / Case: 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)
• Mounting Type: Through Hole (exact match required)

Allowable Variation Parameters:

• Voltage - Rated: May be equal to or greater than 10 V
• Operating Temperature Range: Must encompass or equal -55°C ~ 135°C
• Lifetime @ Temperature: Must be equal to or exceed 2000 Hrs @ 135°C
• Ripple Current: May be equal to or greater than specified values
• Impedance: May be equal to or lower than specified values

The UBW1C331MPD1TD qualifies as a substitute because it maintains identical capacitance, tolerance, physical dimensions, lead spacing, and mounting configuration while providing upgraded voltage rating (16 V vs. 10 V) and improved electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both the UBW1A331MPD1TD and UBW1C331MPD1TD maintain active product status and full compliance with ROHS3 and REACH requirements. The UBW1C331MPD1TD provides enhanced electrical performance through higher voltage rating, improved ripple current handling, and reduced impedance while maintaining identical physical form factor and thermal characteristics. Selection between these parts depends on circuit voltage requirements: the 10 V rated part is suitable for applications with maximum operating voltages at or below 10 V, while the 16 V rated substitute accommodates higher voltage environments within the same mechanical footprint.

Frequently Asked Questions (FAQ)

Q: Can the UBW1C331MPD1TD replace the UBW1A331MPD1TD in existing designs?

A: Yes. The substitute part maintains identical capacitance (330 µF), tolerance (±20%), physical dimensions, lead spacing (5.00mm), and mounting configuration. The higher voltage rating (16 V vs. 10 V) and improved electrical characteristics (higher ripple current, lower impedance) are compatible with circuits designed for the original 10 V part.

Q: What is the primary difference between these two parts?

A: The rated voltage differs: UBW1A331MPD1TD is rated at 10 V, while UBW1C331MPD1TD is rated at 16 V. The substitute also provides improved ripple current capacity and lower impedance within the same package.

Q: Are the physical dimensions identical?

A: Yes. Both parts share identical dimensions (0.394" diameter, 0.571" maximum height), lead spacing (5.00mm), and radial can package configuration, ensuring direct mechanical compatibility on printed circuit boards.

Q: Do both parts meet automotive compliance requirements?

A: Yes. Both parts are designated for automotive applications and maintain ROHS3 compliance and REACH affected status.

Q: What is the thermal performance of these capacitors?

A: Both parts maintain 2000 hours lifetime at 135°C and operate across the temperature range of -55°C to 135°C, providing equivalent thermal stability.
