UVR1H331MPD1CV Equivalent & Substitute Parts

Part Overview

The UVR1H331MPD1CV is a 330 µF, 50 V aluminum electrolytic capacitor manufactured by Nichicon in a radial, can package. This component is rated for 2000 hours at 85°C and is designed for general-purpose applications requiring stable capacitance and reliable performance across industrial temperature ranges. The main part is currently in active production status with 752 units in stock.

Equivalent and substitute parts become necessary when the primary part number is unavailable, when design revisions require updated component specifications, or when alternative manufacturers offer improved availability or performance characteristics within the same electrical and mechanical parameters.

Substitute Part Grouping Explanation

Substitution eligibility for the UVR1H331MPD1CV is determined by strict adherence to the following parameters:

Electrical Parameters: Capacitance value of 330 µF, voltage rating of 50 V, and tolerance of ±20% are mandatory for functional equivalence.
Thermal Specifications: Lifetime rating of 2000 hours at 85°C and operating temperature range of -40°C to 85°C must be maintained.
Mechanical Compatibility: Radial, can package with lead spacing of 0.197" (5.00 mm), diameter of 0.394" (10.00 mm), and height of 0.689" (17.50 mm) ensure direct board-level substitution without layout modifications.
Polarization: Polar configuration is required for circuit compatibility.

All substitute parts listed meet these criteria across all specified parameters.

Engineering Selection Recommendations

Primary Recommendation: UVR1H331MPD1CV remains the preferred choice for new designs due to its active product status and adequate inventory availability.

Secondary Recommendation: 337CKS050M (Cornell Dubilier / Illinois Capacitor) is suitable as a substitute when UVR1H331MPD1CV availability is constrained. This part maintains active product status and offers the highest inventory level (7259 units) among substitute options. All electrical and mechanical parameters are identical to the main part.

Alternative Option: 50PK330MEFC10X16 (Rubycon) provides a third-source option with active product status. Inventory is lower (915 units) but remains available for immediate procurement.

Legacy Consideration: UVR1H331MPD (Nichicon) is marked as "Not For New Designs" and should be avoided in new circuit designs despite high inventory availability (14329 units). This part is suitable only for repair or maintenance of existing equipment using the original specification.

All substitute parts carry RoHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component procurement.

Frequently Asked Questions (FAQ)

Q: Can I substitute UVR1H331MPD1CV with UVR1H331MPD in a new design?

A: No. UVR1H331MPD is marked "Not For New Designs" and should be reserved for legacy equipment repair only. Use 337CKS050M or 50PK330MEFC10X16 for new designs.

Q: Are all substitute parts mechanically identical to the main part?

A: Yes. All substitute parts share identical lead spacing (0.197" / 5.00 mm), diameter (0.394" / 10.00 mm), and height (0.689" / 17.50 mm). Direct board-level substitution is possible without PCB layout modifications.

Q: What electrical parameters must remain constant for substitution?

A: Capacitance (330 µF), voltage rating (50 V), tolerance (±20%), lifetime (2000 hours at 85°C), and operating temperature range (-40°C to 85°C) are non-negotiable for functional equivalence.

Q: Do all substitute parts meet current compliance standards?

A: Yes. All listed substitute parts are RoHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement.

Q: Which substitute part offers the best availability?

A: 337CKS050M provides the highest inventory level at 7259 units with active product status, making it the most readily available substitute option.

Q: Can I use these parts interchangeably on the same PCB?

A: Yes. All parts are mechanically and electrically equivalent within the specified parameters and can be used interchangeably without circuit redesign or board layout modification.
