Equivalent & Substitute Parts for 475RSS035M

Part Overview

The Cornell Dubilier 475RSS035M is a 4.7 µF, 35 V aluminum electrolytic capacitor in radial, can package configuration. This component is classified as Active product status and is designed for general-purpose applications requiring through-hole mounting. The part is ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified based on matching or exceeding the core electrical specifications: capacitance value of 4.7 µF, voltage rating of 35 V or higher, radial can package format, and through-hole mounting compatibility. Equivalent alternatives are necessary when the primary part becomes unavailable or when design requirements necessitate enhanced performance characteristics such as extended operating temperature ranges or improved lifetime ratings.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 475RSS035M is determined by the following criteria:

Primary Matching Parameters:

• Capacitance value: 4.7 µF (exact match required)
• Voltage rating: 35 V minimum (equal or higher ratings acceptable)
• Package configuration: Radial, can format
• Mounting method: Through-hole
• Lead spacing: 0.059" (1.50mm)
• Physical dimensions: 0.157" diameter, 0.315" maximum height
• Polarization: Polar

Secondary Compatibility Parameters:

• Tolerance: ±20%
• RoHS compliance: ROHS3 Compliant
• REACH status: REACH Unaffected

The identified substitute parts maintain identical capacitance, package geometry, and mounting characteristics. Variations in voltage rating, operating temperature range, and lifetime specifications represent design enhancements rather than functional deviations.

Engineering Selection Recommendations

475RSS035M (Cornell Dubilier / Illinois Capacitor) - Primary Selection

The 475RSS035M maintains Active product status with current manufacturing availability. This part is the preferred choice for new designs and applications where component continuity is required. The part meets ROHS3 compliance and REACH unaffected status, suitable for regulated applications.

35MH74.7MEFC4X7 (Rubycon MH7 Series) - Equivalent Substitute

The Rubycon 35MH74.7MEFC4X7 provides electrical equivalence with identical capacitance, voltage rating, and package geometry. This part features an extended operating temperature range of -40°C to 105°C compared to the primary part's -40°C to 85°C specification. The part is classified as Obsolete, indicating limited availability. ROHS3 compliance and REACH unaffected status are maintained. Selection of this substitute is appropriate when enhanced thermal performance is required within the same voltage class.

50MS74.7MEFC4X7 (Rubycon MS7 Series) - Voltage-Upgraded Substitute

The Rubycon 50MS74.7MEFC4X7 provides functional equivalence with a voltage rating of 50 V, exceeding the 35 V requirement of the primary part. Capacitance, tolerance, and package dimensions remain identical. Operating temperature range matches the primary part at -40°C to 85°C. This part is classified as Obsolete. ROHS3 compliance and REACH unaffected status are maintained. Selection of this substitute is appropriate for applications requiring higher voltage margin or when 35 V rated components are unavailable.

Frequently Asked Questions (FAQ)

Q: Can the 35MH74.7MEFC4X7 be used as a direct replacement for the 475RSS035M?

A: Yes. Both parts share identical capacitance (4.7 µF), voltage rating (35 V), tolerance (±20%), lead spacing (0.059"), physical dimensions (0.157" diameter, 0.315" height), and through-hole radial can package configuration. The 35MH74.7MEFC4X7 provides an extended operating temperature range to 105°C.

Q: Can the 50MS74.7MEFC4X7 be used as a direct replacement for the 475RSS035M?

A: Yes. Both parts share identical capacitance (4.7 µF), tolerance (±20%), lead spacing (0.059"), physical dimensions (0.157" diameter, 0.315" height), and through-hole radial can package configuration. The 50MS74.7MEFC4X7 has a higher voltage rating of 50 V, which exceeds the 35 V requirement and provides additional voltage margin.

Q: What is the significance of the Obsolete product status for the substitute parts?

A: Obsolete status indicates that Rubycon has discontinued manufacturing of the 35MH74.7MEFC4X7 and 50MS74.7MEFC4X7 series. While these parts may be available through existing inventory channels, future procurement cannot be guaranteed. The Active status of the 475RSS035M ensures ongoing availability for new production requirements.

Q: Are all three parts RoHS3 compliant?

A: Yes. The 475RSS035M, 35MH74.7MEFC4X7, and 50MS74.7MEFC4X7 are all ROHS3 compliant and REACH unaffected, meeting regulatory requirements for restricted substance use.

Q: What is the difference in ripple current specifications between the parts?

A: The 475RSS035M specifies 25 mA at 120 Hz and 35 mA at 100 kHz. The Rubycon substitutes specify 24 mA at 120 Hz and 36 mA at 10 kHz. These variations reflect different measurement standards and frequency points but do not affect functional compatibility for general-purpose applications.

Q: Can I use a 50 V rated capacitor in a circuit designed for 35 V?

A: Yes. A 50 V rated capacitor (50MS74.7MEFC4X7) can be used in a 35 V circuit. The higher voltage rating provides additional safety margin and does not negatively affect circuit operation. The capacitor will operate within its rated specifications.

Q: Are the physical dimensions identical across all three parts?

A: Yes. All three parts share identical lead spacing (0.059" or 1.50mm), diameter (0.157" or 4.00mm), and maximum seated height (0.315" or 8.00mm), ensuring direct mechanical compatibility in through-hole PCB applications.
