Engineering Selection Recommendations

RFS-50VR47MF3#5 (Primary Selection)

The RFS-50VR47MF3#5 remains the preferred component for new designs and applications where the specified 50 V rating and 1000-hour lifetime at 85°C meet circuit requirements. This part maintains Active product status with full RoHS3 compliance and REACH unaffected designation. Current inventory of 889 pieces supports immediate procurement.

UPW2CR47MED (Substitute Selection)

The UPW2CR47MED is a valid substitute when the primary part is unavailable or when circuit design permits operation at the higher 160 V rating and extended temperature range to 105°C. This Nichicon component provides enhanced reliability with 2000-hour lifetime at 105°C. However, the Obsolete product status indicates this part is no longer in active production. The substitute maintains identical mechanical dimensions, lead spacing, and mounting configuration, ensuring direct board-level compatibility. RoHS3 compliance and REACH unaffected status are maintained. Inventory availability of 2704 pieces is currently reported.

Compliance Considerations

Both parts satisfy RoHS3 compliance requirements and carry REACH unaffected designation. ECCN classification (EAR99) and HTSUS code (8532.22.0020) are identical for both components.

Frequently Asked Questions (FAQ)

Q: Can the UPW2CR47MED be used as a direct replacement for the RFS-50VR47MF3#5 on existing circuit boards?

A: Yes. The UPW2CR47MED provides identical mechanical dimensions, lead spacing (0.098" / 2.50 mm), case diameter (0.248" / 6.30 mm), and height (0.433" / 11.00 mm). Both components are through-hole mounted radial cans with identical polarization. No PCB layout modifications are required.

Q: What is the primary difference between these two parts?

A: The UPW2CR47MED is rated for 160 V compared to the RFS-50VR47MF3#5 at 50 V. Additionally, the Nichicon substitute operates to 105°C versus 85°C for the Elna part, and provides 2000-hour lifetime at 105°C versus 1000 hours at 85°C for the primary part. Capacitance, tolerance, and ripple current specifications are identical.

Q: Are there any electrical performance differences in audio applications?

A: Both components maintain identical capacitance (0.47 µF), tolerance (±20%), and ripple current at 120 Hz (12 mA). The substitute's higher voltage rating and extended temperature range do not alter performance in audio circuits operating within the original part's specifications.

Q: Why is the substitute part listed as Obsolete?

A: The UPW2CR47MED carries Obsolete product status, indicating Nichicon has discontinued active production. However, current inventory of 2704 pieces is available. For long-term production requirements, the Active status RFS-50VR47MF3#5 is recommended.

Q: Can the RFS-50VR47MF3#5 be used in applications requiring the 160 V rating of the UPW2CR47MED?

A: No. The RFS-50VR47MF3#5 is rated for maximum 50 V operation. Using this part in circuits requiring 160 V rating would exceed component specifications and create reliability risk.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the RFS-50VR47MF3#5 and UPW2CR47MED are RoHS3 compliant with REACH unaffected designation, suitable for applications with environmental compliance requirements.

Q: What is the lead spacing for both components?

A: Both components feature 0.098" (2.50 mm) lead spacing, ensuring compatibility with standard through-hole PCB layouts designed for radial aluminum electrolytic capacitors in this package class.
