Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the UVZ2F4R7MPD are selected based on the following criteria:

Mandatory Matching Parameters:

• Capacitance: 4.7 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial, Can (exact match required)
• Lead Spacing: 0.197" (5.00mm) (exact match required)
• Size / Dimension: 0.394" Dia (10.00mm) (exact match required)
• Operating Temperature Range: -40°C ~ 105°C (exact match required)

Allowable Variation Parameters:

• Voltage - Rated: May be equal to or greater than 315 V
• Height - Seated (Max): May vary within mechanical compatibility limits
• Lifetime @ Temperature: May be equal to or greater than 2000 Hrs @ 105°C
• Ripple Current @ Low Frequency: May vary based on application requirements
• ESR (Equivalent Series Resistance): May vary based on application requirements

Parameter Comparison

Engineering Selection Recommendations

UVZ2V4R7MPD (Nichicon): This part is a direct mechanical and electrical equivalent with identical physical dimensions and electrical characteristics to the UVZ2F4R7MPD, with the exception of a higher rated voltage (350 V vs. 315 V). Both parts share the same series designation (UVZ) and carry identical "Not For New Designs" status. This substitute provides backward compatibility with no design modifications required. ROHS3 compliance is maintained.

SEK4R7M350ST (Cornell Dubilier Electronics): This part meets all mandatory substitution criteria with identical capacitance, tolerance, polarization, mounting type, package, lead spacing, and size. The rated voltage is 350 V, exceeding the original 315 V specification. The height dimension is 0.512" (13.00mm) compared to 0.492" (12.50mm) for the original part, representing a 0.020" (0.50mm) increase. This part carries an "Active" product status and ROHS3 compliance. The ripple current rating is higher at 55 mA @ 120 Hz, and ESR is specified at 56.47 Ohm @ 120 Hz.

Both substitute parts maintain compliance with ROHS3 and REACH requirements. Selection between substitutes depends on PCB layout constraints, particularly regarding the height dimension variation in the SEK4R7M350ST.

Frequently Asked Questions (FAQ)

Q: Can UVZ2V4R7MPD be used as a direct replacement for UVZ2F4R7MPD?

A: Yes. The UVZ2V4R7MPD is mechanically and electrically compatible. All physical dimensions, lead spacing, and electrical parameters match the original part. The higher voltage rating (350 V vs. 315 V) provides additional design margin without requiring circuit modifications.

Q: What is the primary difference between UVZ2V4R7MPD and SEK4R7M350ST?

A: Both parts meet the core substitution criteria. The SEK4R7M350ST has a slightly taller profile (0.512" vs. 0.492") and is manufactured by a different supplier (Cornell Dubilier Electronics vs. Nichicon). The SEK4R7M350ST carries an "Active" product status, while the UVZ2V4R7MPD is "Not For New Designs."

Q: Are there any PCB layout considerations when using SEK4R7M350ST?

A: The SEK4R7M350ST has a maximum seated height of 0.512" (13.00mm), which is 0.020" (0.50mm) taller than the original UVZ2F4R7MPD at 0.492" (12.50mm). Verify that PCB clearance and component spacing accommodate this dimension before substitution.

Q: Do all substitute parts maintain RoHS3 compliance?

A: Yes. Both UVZ2V4R7MPD and SEK4R7M350ST are ROHS3 compliant, matching the compliance status of the original UVZ2F4R7MPD.

Q: What is the significance of the "Not For New Designs" status?

A: This designation indicates that the part is no longer recommended for new product development. However, it remains suitable for maintenance, repair, and legacy system support. The UVZ2V4R7MPD carries the same status, while SEK4R7M350ST is designated "Active" and may be preferred for applications requiring long-term availability assurance.
