Engineering Selection Recommendations

Direct Equivalent Substitution: UVP1H3R3MDD

The Nichicon UVP1H3R3MDD provides direct electrical and mechanical equivalence to the 335BPS050M. Both components share identical capacitance (3.3 µF), voltage rating (50 V), tolerance (±20%), and lifetime specification (2000 hours at 85°C). Physical dimensions are compatible with PCB footprints designed for the Cornell Dubilier part, with lead spacing and can diameter matching exactly. The UVP1H3R3MDD is ROHS3 compliant and REACH unaffected, meeting all regulatory requirements. This part is classified as Obsolete product status.

Upgrade Substitution: UVP1J3R3MDD

The Nichicon UVP1J3R3MDD functions as an upgrade substitute with a higher voltage rating of 63 V compared to the 50 V rating of the 335BPS050M. All other electrical parameters remain equivalent: capacitance (3.3 µF), tolerance (±20%), and lifetime (2000 hours at 85°C). The higher voltage rating provides additional design margin and operational safety in applications where the 50 V specification is a minimum requirement. Physical compatibility is maintained with identical lead spacing (0.079 inches), can diameter (0.197 inches), and through-hole mounting configuration. The UVP1J3R3MDD is ROHS3 compliant and REACH unaffected. This part is classified as Obsolete product status.

Both substitute parts maintain the bi-polar polarization characteristic and operating temperature range (-40°C to 85°C) of the original component. Selection between direct equivalent and upgrade substitution depends on circuit voltage headroom requirements and design specifications.

Frequently Asked Questions (FAQ)

Q: Can the UVP1H3R3MDD be used as a direct replacement for the 335BPS050M?

A: Yes. The UVP1H3R3MDD matches all critical electrical specifications: 3.3 µF capacitance, 50 V voltage rating, ±20% tolerance, and 2000-hour lifetime at 85°C. Physical dimensions and lead spacing are identical, enabling direct PCB substitution without layout modifications.

Q: What is the advantage of using the UVP1J3R3MDD upgrade part?

A: The UVP1J3R3MDD provides a 63 V voltage rating instead of 50 V, offering increased operational margin. All other specifications remain equivalent to the original part. This upgrade is suitable for applications where higher voltage headroom is beneficial or where circuit conditions may approach the 50 V limit.

Q: Are there height clearance differences between these parts?

A: Yes. The 335BPS050M has a maximum seated height of 0.512 inches (13.00 mm), while both Nichicon substitutes (UVP1H3R3MDD and UVP1J3R3MDD) have a maximum seated height of 0.492 inches (12.50 mm). The substitute parts are 0.020 inches shorter, which is advantageous for space-constrained applications and does not affect compatibility with designs accommodating the original part height.

Q: Do these substitute parts meet the same regulatory requirements?

A: Yes. All three parts are ROHS3 compliant and REACH unaffected, meeting current regulatory standards for electronic component manufacturing and use.

Q: What is the difference in ripple current specifications?

A: The 335BPS050M specifies 45.9 mA ripple current at 50 kHz. The UVP1H3R3MDD and UVP1J3R3MDD specify ripple current at 10 kHz (54 mA and 56 mA respectively). These measurements are taken at different frequencies; direct comparison requires application-specific frequency analysis. Both substitute parts demonstrate adequate ripple current performance for the specified 2000-hour lifetime at 85°C.

Q: Can these parts be used interchangeably in audio applications?

A: The 335BPS050M is specified for audio applications. The substitute parts (UVP1H3R3MDD and UVP1J3R3MDD) are specified for general-purpose applications. Both share identical electrical characteristics (capacitance, voltage, tolerance, lifetime) and bi-polar polarization, making them functionally compatible in audio circuit designs. Application-specific performance validation is the responsibility of the design engineer.

Q: What is the significance of the "Obsolete" product status for the substitute parts?

A: Obsolete status indicates that Nichicon has discontinued manufacturing these parts. While inventory may be available from component distributors, long-term supply cannot be guaranteed. The 335BPS050M, classified as Active, remains in current production by Cornell Dubilier / Illinois Capacitor.
