UVZ2F4R7MPH Equivalent & Substitute Parts

Part Overview

The UVZ2F4R7MPH is a 4.7 µF, 315 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing maintenance, repair, and legacy system support. The part operates across a temperature range of -40°C to 105°C with a rated lifetime of 2000 hours at 105°C, serving general-purpose applications requiring polar electrolytic capacitance.

Substitute Part Grouping Explanation

Substitution for the UVZ2F4R7MPH is determined by the following critical parameters:

Capacitance: Must be 4.7 µF (exact match required)
Voltage Rating: Minimum 315 V; higher voltage ratings are acceptable as they provide operational margin
Tolerance: ±20% (standard for aluminum electrolytic capacitors)
Polarization: Polar (required for electrolytic type)
Lead Spacing: 0.197" (5.00 mm) for PCB compatibility
Package Type: Radial, can configuration for through-hole mounting
Operating Temperature: -40°C ~ 105°C minimum range
Lifetime: 2000 Hrs @ 105°C minimum

Substitute parts meeting these criteria are functionally equivalent for circuit applications where the UVZ2F4R7MPH was originally specified.

Engineering Selection Recommendations

UVZ2V4R7MPD (Nichicon Upgrade)

This part is a direct upgrade from the same manufacturer with identical capacitance, tolerance, and mechanical dimensions. The voltage rating increases from 315 V to 350 V, providing additional operational margin. The UVZ2V4R7MPD achieves ROHS3 compliance, addressing regulatory requirements where the original part does not. Product status is "Not For New Designs," indicating limited future availability but current stock presence.

SEK4R7M350ST (Cornell Dubilier Electronics Alternative)

This part maintains all critical electrical parameters: 4.7 µF capacitance, ±20% tolerance, 350 V rating, and 2000-hour lifetime at 105°C. The SEK4R7M350ST is manufactured by Cornell Dubilier Electronics and carries Active product status with ROHS3 compliance. Physical dimensions are compatible with the original specification, with maximum seated height of 0.512" (13.00 mm) versus 0.492" (12.50 mm) for the UVZ2F4R7MPH. This 0.020" height difference must be evaluated for PCB layout constraints. Ripple current capability is higher at 55 mA @ 120 Hz compared to 45 mA for the original part.

Frequently Asked Questions (FAQ)

Q: Can the UVZ2V4R7MPD be used as a direct replacement for the UVZ2F4R7MPH?

A: Yes. Both parts share identical capacitance (4.7 µF), tolerance (±20%), lead spacing (5.00 mm), and physical dimensions. The UVZ2V4R7MPD has a higher voltage rating (350 V vs. 315 V), which is acceptable for applications designed for 315 V operation. Mechanical fit on the PCB is identical.

Q: What is the significance of the voltage rating difference between 315 V and 350 V?

A: A higher voltage rating provides operational margin and does not negatively affect circuit performance in applications rated for lower voltages. The 350 V rated parts can safely operate in circuits designed for 315 V maximum voltage.

Q: Is the SEK4R7M350ST height difference of 0.020" (0.512" vs. 0.492") a concern?

A: The height difference must be evaluated against specific PCB layout constraints and enclosure clearances. If vertical space is limited, this difference may require design review. Lead spacing and diameter remain identical, ensuring footprint compatibility.

Q: What does "Not For New Designs" mean for the UVZ2V4R7MPD?

A: This status indicates the manufacturer is not recommending this part for new circuit designs, typically due to planned discontinuation or replacement by newer alternatives. However, it remains available for legacy system support and repair applications.

Q: Are there RoHS compliance implications when substituting the UVZ2F4R7MPH?

A: The original UVZ2F4R7MPH is RoHS non-compliant. Both substitute parts (UVZ2V4R7MPD and SEK4R7M350ST) are ROHS3 compliant. If the application or end-use market requires RoHS compliance, substitution with either alternative part addresses this requirement.

Q: How do ripple current ratings affect part selection?

A: The UVZ2F4R7MPH and UVZ2V4R7MPD both support 45 mA @ 120 Hz ripple current. The SEK4R7M350ST supports 55 mA @ 120 Hz, providing higher ripple current capacity. If the circuit requires ripple current handling above 45 mA, the SEK4R7M350ST is the preferred choice.
