Substitute Part Grouping Explanation

Substitution of the UVY1V331MPD is determined by strict equivalence in the following parameters:

Capacitance: 330 µF (exact match required)
Voltage Rating: 35 V (exact match required)
Tolerance: ±20% (exact match required)
Polarization: Polar (exact match required)
Mounting Type: Through Hole (exact match required)
Package: Radial, Can (exact match required)
Lead Spacing: 0.197" (5.00 mm) (exact match required)
Operating Temperature Range: -55°C ~ 105°C (exact match required)

Substitute parts are grouped into three categories based on lifetime rating and product status:

Direct Substitutes (Same Lifetime): URZ1V331MPD and UVZ1V331MPD maintain the 2000-hour lifetime specification but differ in height or product status.

Upgrade Substitutes (Extended Lifetime): UKA1V331MPD, UPJ1V331MHD6, UPJ1V331MPD, UPM1V331MHD6, UPM1V331MPD, UPS1V331MPD, UPW1V331MPD, and UPW1V331MPD6 offer 5000-hour or extended lifetime ratings, providing improved reliability margins.

Mechanical Variations: Some substitutes differ in physical dimensions (diameter and height) while maintaining electrical equivalence. Lead spacing remains constant at 0.197" (5.00 mm) across all substitutes.

Frequently Asked Questions (FAQ)

Q: Can URZ1V331MPD be used as a direct replacement for UVY1V331MPD?

A: URZ1V331MPD is electrically equivalent in capacitance, voltage, tolerance, and package. However, it offers reduced lifetime (1000 hours vs. 2000 hours at 105°C) and is the only substitute with Active product status. Selection depends on application lifetime requirements.

Q: What is the primary difference between UPJ1V331MPD and UPW1V331MPD?

A: Both offer 5000-hour lifetime at 105°C. UPJ1V331MPD has a taller profile (0.846" height) with higher ripple current capability (810 mA at 120 Hz). UPW1V331MPD has a more compact height (0.630") with slightly lower ripple current (682.5 mA at 120 Hz). Selection depends on space constraints and ripple current requirements.

Q: Are automotive-qualified substitutes available?

A: Yes. UPM1V331MHD6 and UPM1V331MPD are qualified to AEC-Q200 automotive standards with 5000-hour lifetime ratings. Both maintain identical electrical specifications and lead spacing.

Q: Does UPW1V331MPD6 have different lead spacing than other substitutes?

A: Yes. UPW1V331MPD6 has lead spacing of 0.138" (4.60 mm) and diameter of 0.315" (8.00 mm), differing from the standard 0.197" (5.00 mm) lead spacing and 0.394" (10.00 mm) diameter of the original part. This part requires PCB layout modification and is not a direct mechanical substitute.

Q: Which substitute offers the best balance of reliability and compact size?

A: UPW1V331MPD provides 5000-hour lifetime with a compact height of 0.630" (16.00 mm) and standard lead spacing of 0.197" (5.00 mm), making it suitable for space-constrained applications requiring extended reliability without PCB redesign.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All listed substitutes maintain ROHS3 compliance. UPM1V331MHD6 and UPM1V331MPD are REACH Affected, while all other substitutes are REACH Unaffected.
