Key Parameters

Substitute Part Grouping Explanation

Substitution relationships for the UBT1A331MPD8 are established based on the following critical parameters: capacitance value (330 µF), tolerance (±20%), polarization (Polar), physical dimensions (0.394" Dia, 14.50mm height, 5.00mm lead spacing), mounting type (Through Hole), package configuration (Radial, Can), and compliance certifications (ROHS3, REACH Affected).

Substitute parts are categorized into two groups:

Direct Equivalents (Packaging Variants): Parts with identical electrical specifications and physical dimensions but different packaging formats. The UBT1A331MPD8TD is supplied in Cut Tape (CT) packaging instead of Bulk, maintaining all electrical and mechanical parameters.

Upgrade Alternatives (Voltage Rating Enhancement): The UBT1C331MPD8 provides the same capacitance (330 µF) and physical form factor with an elevated voltage rating of 16 V (versus 10 V). This part is suitable for applications requiring higher voltage margin while maintaining compatibility with the original footprint and mounting configuration.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain Active product status and ROHS3 compliance, ensuring regulatory alignment for automotive applications. The UBT1A331MPD8TD serves as a direct functional equivalent, differing only in packaging format (Cut Tape versus Bulk). Selection between these two depends on procurement and assembly workflow requirements rather than electrical performance.

The UBT1C331MPD8 upgrade option provides enhanced voltage rating (16 V versus 10 V) while maintaining identical physical footprint and lead spacing. The upgrade also delivers improved electrical performance with lower impedance (100 mOhms versus 150 mOhms) and higher ripple current capability at both low and high frequencies. This part is suitable for designs requiring increased voltage margin or enhanced transient response characteristics within the same form factor.

Frequently Asked Questions (FAQ)

Q: Can UBT1A331MPD8TD be used as a direct replacement for UBT1A331MPD8?

A: Yes. Both parts are electrically and mechanically identical. The difference is packaging format: UBT1A331MPD8TD is supplied in Cut Tape (CT) while UBT1A331MPD8 is supplied in Bulk. Selection depends on assembly process requirements and inventory management practices.

Q: Is UBT1C331MPD8 a compatible substitute for UBT1A331MPD8?

A: Yes, with design consideration. UBT1C331MPD8 maintains identical capacitance (330 µF), physical dimensions, lead spacing, and mounting configuration. The rated voltage is 16 V instead of 10 V, providing higher voltage margin. This part is suitable for applications where the original 10 V rating is adequate, as the higher voltage rating does not create incompatibility. The improved electrical characteristics (lower impedance, higher ripple current) may provide performance benefits.

Q: Do all substitute parts have the same physical footprint?

A: Yes. All three parts share identical lead spacing (0.197" / 5.00mm), diameter (0.394" / 10.00mm), and maximum seated height (0.571" / 14.50mm). PCB layout and mounting hole spacing are interchangeable.

Q: Are there any compliance differences between the main part and substitutes?

A: No. All parts are ROHS3 compliant and REACH Affected. Regulatory status is consistent across all three options.

Q: What is the difference in ripple current capability between the main part and the upgrade?

A: UBT1C331MPD8 provides higher ripple current ratings: 340 mA at 120 Hz (versus 310 mA) and 680 mA at 100 kHz (versus 620 mA). This reflects the improved electrical design of the higher voltage rated part.
