UPW2V4R7MPD Equivalent & Substitute Parts

Part Overview

The UPW2V4R7MPD is a 4.7 µF 350 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is rated for 5000 hours at 105°C and is classified as obsolete. Due to its obsolete status, equivalent and substitute parts from active manufacturers or alternative series are necessary for new designs and ongoing production requirements.

Substitute Part Grouping Explanation

Substitution for the UPW2V4R7MPD is determined by the following critical parameters:

Capacitance: 4.7 µF (exact match required)
Voltage Rating: 350 V minimum (higher voltage ratings are acceptable)
Tolerance: ±20% (standard tolerance)
Lead Spacing: 0.197" (5.00 mm) for direct PCB compatibility
Case Diameter: 0.394" (10.00 mm) for mechanical fit
Mounting Type: Through Hole radial configuration
Operating Temperature: -40°C ~ 105°C range
Polarization: Polar (aluminum electrolytic)

Substitute parts are grouped into the following categories:

Direct Equivalents (Same Voltage, Same Lifetime): Parts maintaining 350 V rating and 5000 hour lifetime at 105°C.

Manufacturer Recommended (Higher Voltage Rating): Parts with 400 V rating, providing voltage margin while maintaining compatible physical dimensions and electrical characteristics.

Active Manufacturer Alternatives: Parts from alternative manufacturers (Chemi-Con, Vishay) with equivalent electrical specifications and active product status.

Similar Series (Reduced Lifetime): Parts with lower lifetime ratings (1000-2500 hours) suitable for applications with reduced reliability requirements.

Engineering Selection Recommendations

For Direct Replacement (Same Specifications): UPW2G4R7MPD is the only Nichicon part maintaining the 5000-hour lifetime specification. This part increases voltage rating to 400 V while preserving identical physical dimensions and thermal performance. Both UPW series parts are classified as obsolete; however, UPW2G4R7MPD remains available in inventory.

For Active Manufacturer Alternatives: EKMG351ELL4R7MJ16S (Chemi-Con, Active status) provides equivalent 350 V rating with compatible lead spacing and through-hole mounting. This part is actively manufactured and ROHS3 compliant. Lifetime is reduced to 1000 hours at 105°C.

MAL214234785E3 and MAL214254785E3 (Vishay, Active status) both provide 2500-hour lifetime at 105°C with 350 V rating. These parts are actively produced and ROHS3 compliant. Physical dimensions differ slightly in height (0.531" vs. 0.787").

SEK4R7M350ST (Cornell Dubilier, Active status) offers 2000-hour lifetime with 350 V rating and is actively manufactured. ROHS3 compliant.

For Higher Voltage Margin: UVZ2G4R7MPD provides 400 V rating with 2000-hour lifetime. Lead spacing and case diameter remain compatible. Height increases to 0.689".

Compliance Considerations: All listed substitutes are ROHS3 compliant and REACH unaffected, matching the original part's regulatory status.

Frequently Asked Questions (FAQ)

Q: Can UVY2V4R7MPD be used as a direct replacement for UPW2V4R7MPD?

A: UVY2V4R7MPD shares the same 4.7 µF capacitance and 350 V rating but has different lead spacing (0.138" vs. 0.197") and smaller case diameter (0.315" vs. 0.394"). PCB layout modifications are required. Lifetime is reduced to 1000 hours at 105°C.

Q: What is the advantage of UPW2G4R7MPD over UPW2V4R7MPD?

A: UPW2G4R7MPD maintains identical physical dimensions and 5000-hour lifetime but increases voltage rating to 400 V. This provides additional voltage margin for the same form factor and thermal performance.

Q: Are Vishay MAL214 series parts pin-compatible with the original UPW2V4R7MPD?

A: Yes. MAL214234785E3 and MAL214254785E3 both maintain 0.197" lead spacing and 0.394" case diameter. Height differs (0.531" vs. 0.787"), which may affect PCB clearance in confined spaces.

Q: Why do some substitutes have lower lifetime ratings?

A: UVY2V4R7MPD, EKMG351ELL4R7MJ16S, and SEK4R7M350ST are from different product series with different thermal performance characteristics. These parts are suitable for applications where 1000-2500 hour lifetime at 105°C meets reliability requirements.

Q: Is the UVZ2V4R7MPD suitable for new designs?

A: UVZ2V4R7MPD is classified as "Not For New Designs." For new designs, select from active manufacturer parts: EKMG351ELL4R7MJ16S (Chemi-Con), MAL214234785E3 or MAL214254785E3 (Vishay), or SEK4R7M350ST (Cornell Dubilier).

Q: What is the difference between MAL214234785E3 and MAL214254785E3?

A: Both parts are electrically and mechanically identical with 4.7 µF, 350 V, 2500-hour lifetime, and compatible lead spacing. The primary difference is packaging: MAL214234785E3 is supplied in Tape & Box format, while MAL214254785E3 is supplied in Bulk packaging.
