Engineering Selection Recommendations

For General-Purpose Applications with Standard Lifetime Requirements:

UVY1V331MPD and UVZ1V331MPD are direct substitutes offering doubled lifetime (2000 hours at 105°C) compared to the URZ1V331MPD baseline. Both maintain identical electrical specifications and ROHS3 compliance. UVZ1V331MPD provides a compact height advantage (0.492" vs. 0.551") while UVY1V331MPD maintains the original height profile.

For Extended Operational Lifetime (5000 Hours @ 105°C):

UPW1V331MPD is the primary recommendation for applications requiring maximum reliability over extended service intervals. It maintains the original 0.394" diameter and 0.197" lead spacing while delivering 5000-hour lifetime rating and 682.5 mA ripple current capacity. UPJ1V331MPD offers identical lifetime with higher ripple current (810 mA) but requires accommodation of increased height (0.846").

For Automotive Applications with AEC-Q200 Certification:

UPM1V331MHD6 and UPM1V331MPD are qualified to AEC-Q200 standard with 5000-hour lifetime. UPM1V331MPD maintains the original 0.394" diameter footprint while UPM1V331MHD6 uses a 0.492" diameter can. Both feature reduced impedance (60-65 mOhms) suitable for automotive power distribution circuits.

For Audio Applications:

UKA1V331MPD is designated for audio-specific applications with 2000-hour lifetime and identical form factor to the URZ baseline. This part is not recommended for new designs but remains available for legacy audio equipment servicing.

Dimensional Constraints:

UPW1V331MPD6 is not recommended as a direct substitute due to non-standard lead spacing (0.138" vs. 0.197") and reduced diameter (0.315" vs. 0.394"), requiring PCB layout redesign.

Frequently Asked Questions (FAQ)

Q: Can UVY1V331MPD or UVZ1V331MPD be used as drop-in replacements for URZ1V331MPD?

A: Yes, both parts are direct substitutes. They maintain identical capacitance (330 µF), voltage rating (35 V), tolerance (±20%), lead spacing (0.197"), and mounting type (through-hole radial). The primary difference is extended lifetime (2000 hours vs. 1000 hours at 105°C). UVZ1V331MPD offers a reduced height profile (0.492" vs. 0.551"), which may provide PCB layout advantages in space-constrained designs.

Q: What is the difference between UPJ1V331MHD6 and UPJ1V331MPD?

A: Both parts share the UPJ series designation and 5000-hour lifetime at 105°C. UPJ1V331MHD6 uses a 0.492" diameter can with 0.650" height, while UPJ1V331MPD uses a 0.394" diameter can with 0.846" height. The diameter difference affects PCB footprint; the height difference affects vertical clearance requirements. Ripple current capacity differs: 780 mA vs. 810 mA at 120 Hz respectively.

Q: Are automotive-qualified parts (UPM series) interchangeable with general-purpose parts (UPW, UPJ series)?

A: Electrically and mechanically, yes. UPM1V331MHD6 and UPM1V331MPD meet AEC-Q200 automotive qualification standards and deliver identical 330 µF, 35 V specifications with 5000-hour lifetime. However, automotive-qualified parts carry REACH Affected status, whereas general-purpose equivalents carry REACH Unaffected status. Selection depends on application regulatory requirements and supply chain compliance obligations.

Q: What does "Not For New Designs" product status mean for substitute parts?

A: This designation indicates the manufacturer has discontinued active production and recommends against incorporating these parts into new product designs. However, these parts remain available from existing inventory for legacy equipment repair, field replacements, and design transitions. For new designs, URZ1V331MPD (Active status) or equivalent parts with Active status should be prioritized.

Q: Can UPW1V331MPD6 replace URZ1V331MPD in existing PCB designs?

A: No. UPW1V331MPD6 features non-standard lead spacing (0.138" vs. 0.197") and reduced diameter (0.315" vs. 0.394"), requiring PCB layout modification. This part is suitable only for new designs with custom footprint accommodation.

Q: How do ripple current ratings affect part selection?

A: Ripple current capacity determines the maximum AC current the capacitor can safely handle without exceeding temperature limits. URZ1V331MPD is rated 340 mA at 120 Hz. Substitute parts with higher ripple current ratings (UPW1V331MPD at 682.5 mA, UPJ1V331MPD at 810 mA) provide design margin for high-frequency switching applications. Selection should match or exceed the application's actual ripple current demand.

Q: What is the significance of impedance values listed for UPJ and UPM series parts?

A: Impedance (measured in milliohms) indicates the capacitor's total opposition to AC current flow at specific frequencies. Lower impedance values (60-100 mOhms in UPJ/UPM series) indicate superior high-frequency performance compared to higher impedance values. This parameter is relevant for power supply filtering and noise suppression applications where frequency response is critical.
