Key Parameters

Substitute Part Grouping Explanation

Substitution of the UPS2V3R3MPD is determined by strict equivalence in the following parameters: capacitance (3.3 µF), tolerance (±20%), rated voltage (350 V minimum), polarization (polar), lead spacing (0.197" / 5.00mm), case diameter (0.394" / 10.00mm), mounting type (through hole radial), and compliance certifications (ROHS3). Parts are grouped into three categories based on product status and operational characteristics:

Direct Equivalents (Same Voltage, Same Lifetime): Parts matching 350 V rating and 2000 Hrs @ 105°C lifetime.

Enhanced Lifetime Alternatives (Same Voltage, Extended Lifetime): Parts matching 350 V rating with extended operational lifetime (5000 Hrs @ 105°C).

Voltage-Upgraded Alternatives (Higher Voltage Rating): Parts with 400 V rating, providing voltage margin while maintaining all other critical parameters.

Cross-Manufacturer Equivalents: Parts from alternative manufacturers meeting identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Identical Specifications): UVZ2V3R3MPD provides electrical equivalence with identical 350 V rating and 2000 Hrs @ 105°C lifetime. Physical height is reduced to 0.492" (12.50mm) compared to the original 0.689" (17.50mm), allowing installation in space-constrained applications. Product status is "Not For New Designs," indicating legacy support availability.

For Extended Service Life: UPW2V3R3MPD offers 5000 Hrs @ 105°C operational lifetime, providing enhanced reliability for applications requiring extended component durability. Height is 0.630" (16.00mm), intermediate between the original and UVZ series. This part remains obsolete but represents an upgrade path for critical applications.

For Voltage Margin: UVZ2G3R3MPD provides 400 V rating while maintaining identical capacitance, tolerance, and 2000 Hrs @ 105°C lifetime. This part is suitable for applications where voltage stress margin is required. Physical dimensions match UVZ2V3R3MPD.

For Active Product Availability: EKMG351ELL3R3MJC5S (Chemi-Con, KMG series) and SEK3R3M350ST (Cornell Dubilier Electronics, SEK series) are both active products meeting 350 V, 3.3 µF specifications. EKMG351ELL3R3MJC5S operates at 1000 Hrs @ 105°C with height 0.551" (14.00mm). SEK3R3M350ST operates at 2000 Hrs @ 105°C with height 0.512" (13.00mm) and specified ESR of 80.42Ohm @ 120Hz. Both are ROHS3 compliant and suitable for new designs.

Compatibility Constraint: UVY2V3R3MPD has reduced lead spacing (0.138" / 4.60mm) and smaller case diameter (0.315" / 8.00mm), making it physically incompatible with the original footprint despite electrical equivalence. This part is not recommended for direct substitution.

Frequently Asked Questions (FAQ)

Q: Can UVZ2V3R3MPD directly replace UPS2V3R3MPD?

A: Yes, electrically and mechanically. Both are 3.3 µF, 350 V, 2000 Hrs @ 105°C with 0.197" (5.00mm) lead spacing and 0.394" (10.00mm) case diameter. The UVZ series has reduced height (0.492" vs 0.689"), which is compatible with most PCB layouts.

Q: What is the advantage of UPW2V3R3MPD over UVZ2V3R3MPD?

A: UPW2V3R3MPD provides extended lifetime of 5000 Hrs @ 105°C compared to 2000 Hrs for UVZ2V3R3MPD. Both maintain 350 V rating and identical lead spacing. Selection depends on application reliability requirements.

Q: Why is UVY2V3R3MPD listed but not recommended?

A: UVY2V3R3MPD has different lead spacing (0.138" vs 0.197") and smaller case diameter (0.315" vs 0.394"), making it physically incompatible with the original PCB footprint despite matching electrical specifications.

Q: Are active products available as replacements?

A: Yes. EKMG351ELL3R3MJC5S (Chemi-Con) and SEK3R3M350ST (Cornell Dubilier Electronics) are both active products meeting 350 V, 3.3 µF specifications with ROHS3 compliance. SEK3R3M350ST matches the original 2000 Hrs @ 105°C lifetime.

Q: What is the benefit of UVZ2G3R3MPD?

A: UVZ2G3R3MPD provides 400 V rating instead of 350 V, offering voltage stress margin for applications where higher voltage headroom is beneficial. All other parameters remain equivalent to UVZ2V3R3MPD.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 Compliant certification, matching the original UPS2V3R3MPD compliance status.

Q: What is the lead spacing requirement for PCB compatibility?

A: The original UPS2V3R3MPD and all recommended direct substitutes (UPW2V3R3MPD, UVZ2V3R3MPD, UVZ2G3R3MPD, EKMG351ELL3R3MJC5S, SEK3R3M350ST) use 0.197" (5.00mm) lead spacing. UVY2V3R3MPD uses 0.138" (4.60mm) and is not footprint-compatible.
