Substitute Part Grouping Explanation

Substitution of the UPM1C331MPD1TA is determined by strict equivalence in the following parameters: capacitance (330 µF), tolerance (±20%), voltage rating (16 V or higher), polarization (polar), package type (radial can), lead spacing (0.138" / 4.60mm), physical dimensions (0.315" diameter), and mounting type (through hole). The substitute parts are grouped into three categories based on their relationship to the main part:

Direct Manufacturer Equivalent (UPJ1C331MPD1TD): Identical electrical specifications and physical dimensions. Differs in series designation and application classification (general purpose vs. automotive).

Upgrade Substitute (UPW1E331MPD6TD): Higher voltage rating (25 V vs. 16 V) with identical capacitance and tolerance. Maintains compatible physical footprint and lead spacing. Represents a voltage-upgraded alternative.

Parametric Equivalent (UPM1C331MPD1TD): Identical series, electrical specifications, and physical dimensions. Differs only in packaging designation (tape reel vs. cut tape).

Engineering Selection Recommendations

For Automotive Applications with AEC-Q200 Requirement: UPM1C331MPD1TD is the primary equivalent. It maintains identical electrical specifications, physical dimensions, and automotive-grade AEC-Q200 certification as the original UPM1C331MPD1TA. The only difference is packaging format (tape reel vs. cut tape).

For General Purpose Applications: UPJ1C331MPD1TD provides direct electrical and mechanical compatibility. This part is suitable for non-automotive applications where AEC-Q200 certification is not required. Note the slightly reduced height (0.630" vs. 0.650") and increased impedance (180 mOhms vs. 120 mOhms).

For Voltage-Upgraded Applications: UPW1E331MPD6TD offers a higher voltage rating (25 V) while maintaining the same capacitance, tolerance, and physical footprint. This part is applicable in circuits where increased voltage margin is beneficial. Impedance is lower (85 mOhms), and ripple current capacity is higher (474.5 mA vs. 455 mA).

All substitute parts maintain ROHS3 compliance and identical lead spacing and diameter specifications, ensuring direct PCB footprint compatibility.

Frequently Asked Questions (FAQ)

Q: Can UPJ1C331MPD1TD replace UPM1C331MPD1TA in automotive applications? A: UPJ1C331MPD1TD is electrically and mechanically compatible but lacks AEC-Q200 automotive certification. Use only in non-automotive or non-safety-critical applications.

Q: What is the difference between UPM1C331MPD1TA and UPM1C331MPD1TD? A: Both parts are identical in electrical specifications, physical dimensions, and automotive ratings. The difference is packaging: UPM1C331MPD1TA is supplied in cut tape, while UPM1C331MPD1TD is supplied in tape reel format.

Q: Can UPW1E331MPD6TD be used as a direct replacement? A: Yes, UPW1E331MPD6TD is mechanically and electrically compatible. The 25 V rating provides higher voltage margin than the original 16 V specification. Physical dimensions and lead spacing are identical.

Q: Are all substitute parts ROHS3 compliant? A: Yes, all listed substitute parts (UPJ1C331MPD1TD, UPW1E331MPD6TD, and UPM1C331MPD1TD) are ROHS3 compliant.

Q: Does the height difference between UPJ1C331MPD1TD (0.630") and the main part (0.650") affect compatibility? A: The 0.020" (0.50mm) height difference is within typical PCB clearance tolerances. Verify clearance in your specific application layout.

Q: What is the impedance difference between substitute parts? A: UPM1C331MPD1TA and UPM1C331MPD1TD both have 120 mOhms impedance. UPJ1C331MPD1TD has 180 mOhms, and UPW1E331MPD6TD has 85 mOhms. Lower impedance may improve high-frequency performance.
