Key Parameters

Substitute Part Grouping Explanation

Substitution of the UPW2FR47MPD is determined by strict equivalence across the following critical parameters:

• Capacitance Value: Must remain 0.47 µF
• Tolerance: Must maintain ±20%
• Polarization: Must be polar (aluminum electrolytic)
• Mounting Configuration: Must be through-hole radial with identical lead spacing (0.138" / 4.60 mm)
• Physical Dimensions: Case diameter and height must match (0.315" Dia × 0.453" Height Max)
• Operating Temperature Range: Must support -40°C ~ 105°C
• Lifetime Rating: Must provide 3000 Hrs @ 105°C minimum

The UPW2VR47MPD qualifies as a direct substitute based on identical capacitance, tolerance, physical form factor, lead spacing, temperature range, and lifetime specifications. The voltage rating differential (350 V vs. 315 V) represents an upgrade path within the same product family, maintaining all mechanical and thermal characteristics while providing enhanced voltage margin.

Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for applications requiring environmental and hazardous substance certifications. The identical lead spacing, case dimensions, and mounting configuration enable direct PCB-level substitution without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the UPW2VR47MPD replace the UPW2FR47MPD in existing designs?

A: Yes. The UPW2VR47MPD is mechanically and electrically compatible. Identical lead spacing (0.138" / 4.60 mm), case diameter (0.315" / 8.00 mm), and height (0.453" / 11.50 mm) enable direct PCB substitution. Capacitance, tolerance, temperature range, and ripple current specifications are identical.

Q: What is the difference between these two parts?

A: The primary difference is voltage rating. The UPW2VR47MPD is rated at 350 V compared to the UPW2FR47MPD at 315 V. All other parameters—capacitance, tolerance, physical dimensions, thermal characteristics, and ripple current—remain identical.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain ROHS3 compliance and REACH unaffected status. Regulatory certifications are equivalent.

Q: Does the higher voltage rating of the UPW2VR47MPD affect circuit performance?

A: No. The higher voltage rating does not alter capacitance value, tolerance, or frequency response. It provides additional voltage margin without changing functional behavior in the circuit.

Q: Are the physical dimensions identical for PCB mounting?

A: Yes. Lead spacing, case diameter, and seated height are identical. No PCB layout modifications are required for substitution.
