Equivalent & Substitute Parts for UVR1V331MPA

Part Overview

The UVR1V331MPA is a 330 µF, 35 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is classified as obsolete, with 977 pieces available in current inventory. The part operates across a temperature range of -40°C to 85°C with a rated lifetime of 2000 hours at 85°C, suitable for general-purpose applications requiring polarized capacitive energy storage and filtering.

Due to its obsolete status, direct replacement with active or not-for-new-designs alternatives is necessary for ongoing production and design continuity. Substitute parts maintain the core electrical specifications while offering improved product status, enhanced thermal performance, or extended operational lifetime.

Engineering Selection Recommendations

Primary Recommendation: URS1V331MPD (Nichicon)

URS1V331MPD is the optimal direct replacement. It maintains identical electrical and mechanical specifications to the UVR1V331MPA while offering active product status and ROHS3 compliance. This part provides continuity within the Nichicon product ecosystem with equivalent ripple current performance (480 mA @ 120 Hz, 720 mA @ 10 kHz) and identical thermal operating range (-40°C to 85°C).

Secondary Recommendation: B41821A7337M000 (EPCOS - TDK Electronics)

B41821A7337M000 provides an alternative from a different manufacturer with active status and ROHS3 compliance. It matches the thermal profile and lifetime rating of the original part (2000 Hrs @ 85°C) with equivalent ripple current (490 mA @ 120 Hz). Height is 0.531" (14.60 mm), within acceptable tolerance of the 0.551" (14.00 mm) maximum.

Enhanced Performance Options:

For applications requiring extended operational lifetime or elevated temperature operation:

35YXJ330M10X12.5 (Rubycon): 10000 Hrs @ 105°C, active status, ROHS3 compliant
35ZLH330MEFC10X12.5 (Rubycon): 10000 Hrs @ 105°C, active status, ROHS3 compliant
UHV1V331MPD (Nichicon): 6000 Hrs @ 105°C, extended temperature range to 105°C

All substitute parts are ROHS3 compliant, addressing regulatory requirements not met by the obsolete UVR1V331MPA.

Frequently Asked Questions (FAQ)

Q: Can URS1V331MPD be used as a direct replacement for UVR1V331MPA?

A: Yes. URS1V331MPD maintains all mandatory electrical and mechanical parameters: 330 µF capacitance, 35 V voltage rating, ±20% tolerance, radial can package, 0.197" lead spacing, 0.394" diameter, and 0.551" height. Operating temperature range and lifetime rating are identical (-40°C to 85°C, 2000 Hrs @ 85°C). No circuit modifications are required.

Q: What is the difference between UVR1V331MPD and URS1V331MPD?

A: Both are Nichicon 330 µF, 35 V radial capacitors with identical electrical specifications. UVR1V331MPD carries "Not For New Designs" status, while URS1V331MPD is active. For new production, URS1V331MPD is the preferred choice.

Q: Can I use 35YXJ330M10X12.5 in place of UVR1V331MPA?

A: Yes, with performance enhancement. 35YXJ330M10X12.5 is a Rubycon part with identical core specifications (330 µF, 35 V, ±20%, radial can, through-hole) and mechanical footprint. It offers superior lifetime (10000 Hrs @ 105°C versus 2000 Hrs @ 85°C) and extended operating temperature to 105°C. No circuit modifications required.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance. The original UVR1V331MPA is RoHS non-compliant. Substitution addresses both obsolescence and regulatory requirements.

Q: What is the height tolerance between parts?

A: The original UVR1V331MPA specifies 0.551" (14.00 mm) maximum height. B41821A7337M000 has a height of 0.531" (14.60 mm). This 0.020" (0.50 mm) difference is within standard PCB design tolerances for radial capacitor mounting and does not affect board-level compatibility.

Q: Which substitute offers the best ripple current performance?

A: 35ZLH330MEFC10X12.5 provides the highest ripple current capacity: 731.5 mA @ 120 Hz and 1.33 A @ 100 kHz. This part is suitable for applications with demanding AC current requirements while maintaining the 330 µF, 35 V specification.

Q: Can I mix different substitute parts in the same circuit?

A: Yes. All substitute parts meet the mandatory electrical and mechanical parameters. However, for consistency in production and field serviceability, using a single part number across identical circuit positions is recommended.
