Key Parameters

Substitute Part Grouping Explanation

Substitution of the USP1C4R7MDD is determined by the following critical parameters:

• Capacitance Value: Must be 4.7 µF (exact match required)
• Voltage Rating: Must be equal to or greater than 16 V
• Tolerance: ±20% or better
• Polarization: Bi-Polar
• Mounting Type: Through Hole
• Package Type: Radial, Can
• Operating Temperature Range: Must support -40°C ~ 85°C minimum
• Lifetime Rating: Must meet or exceed 2000 Hrs @ 85°C

The substitute part UVP1V4R7MDD meets these criteria with a higher voltage rating (35 V) and improved ripple current handling, making it electrically compatible while providing enhanced performance margins.

Parameter Comparison

Engineering Selection Recommendations

The UVP1V4R7MDD is a valid substitute for the obsolete USP1C4R7MDD based on the following factors:

Electrical Compatibility: Both components share identical capacitance (4.7 µF), tolerance (±20%), polarization (Bi-Polar), and operating temperature range (-40°C ~ 85°C). The UVP1V4R7MDD provides a higher voltage rating (35 V vs. 16 V), which is acceptable for applications designed for 16 V operation and provides additional safety margin.

Thermal Performance: Both parts maintain 2000 hours lifetime at 85°C, meeting identical thermal specifications.

Regulatory Compliance: Both components are ROHS3 compliant and REACH unaffected, satisfying current environmental and regulatory requirements.

Physical Considerations: The UVP1V4R7MDD has larger physical dimensions (0.197" diameter, 0.492" height) and different lead spacing (0.079" vs. 0.059") compared to the main part. PCB layout verification is required to confirm mechanical fit within the available space and lead hole positioning.

Frequently Asked Questions (FAQ)

Q: Can the UVP1V4R7MDD directly replace the USP1C4R7MDD without circuit modification?

A: Electrical substitution is valid. The higher voltage rating (35 V) is compatible with 16 V circuit applications. However, physical dimensions differ; verify PCB footprint compatibility before installation.

Q: What is the significance of the voltage rating difference?

A: The UVP1V4R7MDD's 35 V rating exceeds the circuit requirement of 16 V. This provides operational margin and does not affect circuit function. The capacitance value and tolerance remain identical.

Q: Are there lead spacing or mounting concerns?

A: Yes. The UVP1V4R7MDD has 0.079" (2.00mm) lead spacing versus the original 0.059" (1.50mm). Verify that PCB holes and pad spacing accommodate the larger lead pitch before substitution.

Q: Do both parts meet current compliance standards?

A: Both components are ROHS3 compliant and REACH unaffected, meeting current environmental regulations.

Q: What is the ripple current difference between these parts?

A: The UVP1V4R7MDD supports 34 mA ripple current at 120 Hz, compared to 18 mA for the USP1C4R7MDD. This enhanced ripple current capability provides additional performance margin in applications with AC ripple voltage.
