RFS-50VR47ME3#5 Equivalent & Substitute Parts

Part Overview

The RFS-50VR47ME3#5 is a 0.47 µF, 50 V aluminum electrolytic capacitor in radial, can package manufactured by Elna America. This component is part of the RFS/SILMIC II series and is rated for 1000 hours at 85°C operating temperature. The part is classified as obsolete, making identification of equivalent and substitute components essential for ongoing design support, maintenance, and production continuity. Substitute parts must maintain electrical equivalence across capacitance, voltage rating, tolerance, and thermal performance specifications while accommodating mechanical form factor variations within acceptable design parameters.

Substitute Part Grouping Explanation

Substitute parts for the RFS-50VR47ME3#5 are identified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

Electrical Equivalence Requirements:

• Capacitance: 0.47 µF (exact match required)
• Voltage Rating: 50 V (exact match required)
• Tolerance: ±20% (exact match required)
• Operating Temperature Range: -40°C to 85°C (exact match required)
• Polarization: Polar (exact match required)

Mechanical Compatibility Parameters:

• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial, Can (exact match required)
• Lead Spacing: 0.079" (2.00mm) or 0.098" (2.50mm) acceptable within PCB layout constraints
• Size / Dimension: 0.197" Dia (5.00mm) or 0.248" Dia (6.30mm) acceptable within board space constraints
• Height - Seated (Max): 0.433" (11.00mm) (exact match required)

Compliance Requirements:

• RoHS Status: ROHS3 Compliant (required)
• REACH Status: REACH Unaffected (required)

Substitutes are grouped into two categories: direct equivalents (same manufacturer, same series) and upgraded alternatives (different manufacturer, enhanced thermal performance).

Engineering Selection Recommendations

RFS-50VR47MF3#5 (Direct Equivalent - Same Manufacturer)

The RFS-50VR47MF3#5 is the primary substitute for the obsolete RFS-50VR47ME3#5. Both components are manufactured by Elna America within the RFS/SILMIC II series and share identical electrical specifications: 0.47 µF capacitance, 50 V voltage rating, ±20% tolerance, and -40°C to 85°C operating temperature range. The RFS-50VR47MF3#5 holds active product status, ensuring continued availability and supply chain support. Mechanical compatibility is maintained across all critical dimensions with identical height (0.433" maximum seated height). The lead spacing increases from 0.079" to 0.098" and the can diameter increases from 0.197" to 0.248", both variations accommodated within standard PCB layout tolerances for through-hole radial capacitors. Both components are ROHS3 compliant and REACH unaffected. The RFS-50VR47MF3#5 demonstrates higher ripple current capability at 120 Hz (12 mA versus 9 mA), providing enhanced performance margin in audio applications.

515D474M050JA6AE3 (Upgraded Alternative - Different Manufacturer)

The 515D474M050JA6AE3 manufactured by Vishay Sprague serves as an upgraded alternative with enhanced thermal performance. Electrical specifications remain equivalent: 0.47 µF, 50 V, ±20% tolerance, and -40°C to 85°C operating temperature. The 515D series provides doubled thermal lifetime (2000 hours at 85°C versus 1000 hours), extending component reliability in sustained high-temperature environments. Mechanical form factor matches the original RFS-50VR47ME3#5 precisely: identical lead spacing (0.079"), can diameter (0.197"), and height (0.433"). Both components are ROHS3 compliant and REACH unaffected. The 515D474M050JA6AE3 is classified as obsolete; however, inventory availability is documented at 1430 pieces. This part is suitable for applications requiring extended thermal endurance or as a long-term inventory reserve component.

Frequently Asked Questions (FAQ)

Q: Can RFS-50VR47MF3#5 be used as a direct replacement for RFS-50VR47ME3#5?

A: Yes. Both components share identical electrical specifications (0.47 µF, 50 V, ±20%, -40°C to 85°C) and mechanical mounting requirements (through-hole, radial can package, 0.433" height). The RFS-50VR47MF3#5 is the active production equivalent. Lead spacing and can diameter variations (0.098" spacing and 0.248" diameter versus 0.079" and 0.197") are within acceptable PCB layout tolerances for radial capacitor footprints.

Q: What is the difference between the RFS-50VR47MF3#5 and 515D474M050JA6AE3?

A: Both maintain electrical equivalence at 0.47 µF, 50 V. The primary difference is thermal lifetime: RFS-50VR47MF3#5 is rated 1000 hours at 85°C, while 515D474M050JA6AE3 is rated 2000 hours at 85°C. The 515D series provides extended reliability in high-temperature applications. Mechanical form factors are identical for the 515D474M050JA6AE3 (0.079" lead spacing, 0.197" diameter, 0.433" height), matching the original RFS-50VR47ME3#5 precisely.

Q: Are there mechanical constraints when substituting the RFS-50VR47MF3#5?

A: The RFS-50VR47MF3#5 has a larger can diameter (0.248" versus 0.197") and increased lead spacing (0.098" versus 0.079"). These variations require verification against PCB layout constraints. Height remains identical at 0.433" maximum. Confirm available board space and hole spacing before implementation.

Q: Do all substitute parts meet RoHS and REACH compliance?

A: Yes. RFS-50VR47MF3#5 and 515D474M050JA6AE3 are both ROHS3 compliant and REACH unaffected, matching the compliance status of the original RFS-50VR47ME3#5.

Q: Which substitute should be selected for new designs?

A: RFS-50VR47MF3#5 is recommended for new designs due to active product status, ensuring long-term supply availability. The component is electrically and mechanically compatible with standard through-hole radial capacitor footprints.

Q: Can the 515D474M050JA6AE3 be used in audio applications?

A: The 515D474M050JA6AE3 is classified for general-purpose applications. The original RFS-50VR47ME3#5 and RFS-50VR47MF3#5 are specified for audio applications. While electrical parameters are equivalent, application-specific performance characteristics (such as audio frequency response or noise profile) are not provided for the 515D series in the available data.
