Engineering Selection Recommendations

Direct Substitutes (Same Voltage, Active Status):

URS1V331MPD is the primary direct substitute. It maintains the same 330 µF capacitance, ±20% tolerance, 35 V rating, and 2000-hour lifetime at 85°C operating temperature. The part is Active status, ensuring continued availability. The height is reduced to 0.551" (14.00mm) compared to the original 0.846" (21.50mm), making it suitable for space-constrained applications while maintaining electrical compatibility.

Voltage-Upgraded Substitutes (Active Status):

UBT1V331MPD8 and UBW1V331MPD both provide 35 V ratings with Active product status. UBT1V331MPD8 offers 5000-hour lifetime at 125°C with extended operating range to -40°C ~ 125°C. UBW1V331MPD extends the upper operating temperature to 135°C with -55°C lower limit, suitable for automotive applications. Both maintain the 330 µF, ±20% specification and 0.197" lead spacing. Height increases to 0.866" (22.00mm) for UBT1V331MPD8 and UBW1V331MPD.

UPM1V331MPD is rated for automotive applications with AEC-Q200 compliance, 35 V rating, 5000-hour lifetime at 105°C, and Active status. It accommodates the -55°C ~ 105°C temperature range.

Higher Voltage Substitutes:

UHW1H331MPD provides 50 V rating with extended 10000-hour lifetime at 105°C. UVR1J331MPD offers 63 V rating. Both maintain 330 µF capacitance and ±20% tolerance but are classified as Not For New Designs.

Similar Parts (Same Voltage, Dimensional Variations):

UVK1E331MPD and UVR1E331MPD maintain the 25 V rating and 2000-hour lifetime at 85°C but feature reduced case dimensions. UVK1E331MPD uses 0.138" (4.60mm) lead spacing and 0.315" (8.00mm) case diameter. UVR1E331MPD uses standard 0.197" (5.00mm) lead spacing with 0.394" (10.00mm) case diameter but reduced height of 0.551" (14.00mm). Both are Not For New Designs status.

Frequently Asked Questions (FAQ)

Q: Can URS1V331MPD directly replace UKL1E331MPD?

A: URS1V331MPD is electrically compatible as a direct substitute. Both maintain 330 µF capacitance, ±20% tolerance, and 2000-hour lifetime at 85°C. The voltage rating increases from 25 V to 35 V, which is an allowable upgrade. The primary difference is height: URS1V331MPD measures 0.551" (14.00mm) versus the original 0.846" (21.50mm). Verify PCB layout clearance before substitution.

Q: What is the advantage of UBW1V331MPD over URS1V331MPD?

A: UBW1V331MPD extends the operating temperature range to -55°C ~ 135°C and maintains performance at 135°C, compared to URS1V331MPD's -40°C ~ 85°C range. This makes UBW1V331MPD suitable for high-temperature automotive environments. Both share the same 330 µF, ±20%, 35 V specification and 0.197" lead spacing.

Q: Why do some substitutes have different heights?

A: Height variation reflects different internal construction and thermal performance characteristics. URS1V331MPD and UVR1E331MPD use compact 0.551" (14.00mm) height, while UBT1V331MPD8 and UBW1V331MPD use 0.866" (22.00mm) height to accommodate enhanced thermal performance. Verify PCB mounting clearance and component spacing before selection.

Q: Is UPM1V331MPD suitable for automotive applications?

A: Yes. UPM1V331MPD carries AEC-Q200 automotive qualification, 35 V rating, 5000-hour lifetime at 105°C, and -55°C ~ 105°C operating range. It is Active status with continued availability. Lead spacing and case diameter match the original UKL1E331MPD specification.

Q: Can I use UHW1H331MPD (50 V) in place of UKL1E331MPD (25 V)?

A: UHW1H331MPD is electrically compatible as a voltage upgrade. It maintains 330 µF capacitance, ±20% tolerance, and 0.197" lead spacing. The 50 V rating provides additional safety margin. However, UHW1H331MPD is Not For New Designs status. Height matches the original at 0.846" (21.50mm).

Q: What is the difference between UVK1E331MPD and UVR1E331MPD?

A: Both maintain 25 V rating and 2000-hour lifetime at 85°C. UVK1E331MPD uses reduced lead spacing of 0.138" (4.60mm) and smaller case diameter of 0.315" (8.00mm) with height 0.512" (13.00mm). UVR1E331MPD uses standard 0.197" (5.00mm) lead spacing and 0.394" (10.00mm) case diameter with height 0.551" (14.00mm). UVR1E331MPD is mechanically closer to the original UKL1E331MPD footprint.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance, matching the original UKL1E331MPD specification.
