Equivalent & Substitute Parts for 475SML035M

Part Overview

The Cornell Dubilier 475SML035M is a 4.7 µF, 35 V aluminum electrolytic capacitor in surface mount radial can package. This component is classified as Active product status and is designed for general-purpose applications requiring stable capacitance and voltage ratings in compact SMD form factor. The part is RoHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Substitute parts are identified based on matching core electrical specifications: 4.7 µF capacitance, ±20% tolerance, 35 V rated voltage, surface mount radial can package, and compatible land pattern dimensions. Substitutes must maintain mechanical compatibility with the 0.169" L x 0.169" W (4.30mm x 4.30mm) surface mount land size and 0.157" (4.00mm) diameter constraint.

Substitute Part Grouping Explanation

Substitution eligibility for the 475SML035M is determined by the following mandatory parameters:

Electrical Equivalence Criteria:

• Capacitance: 4.7 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Voltage Rating: 35 V (exact match required)
• Polarization: Polar (exact match required)

Mechanical Compatibility Criteria:

• Package Type: Radial, Can - SMD (exact match required)
• Diameter: 0.157" (4.00mm) (exact match required)
• Surface Mount Land Pattern: 0.169" L x 0.169" W (4.30mm x 4.30mm) (exact match required)
• Mounting Type: Surface Mount (exact match required)

Compliance Criteria:

• RoHS3 Compliant status
• MSL Rating: 1 (Unlimited)

Two substitute parts meet these criteria: MAL215370478E3 (Vishay Beyschlag/Draloric/BC Components) and UWJ1V4R7MCL1GB (Nichicon). Both parts satisfy all mandatory electrical and mechanical parameters. Differences exist in ESR characteristics, temperature ratings, and product status, which are documented in the parameter comparison table below.

Engineering Selection Recommendations

MAL215370478E3 (Vishay Beyschlag/Draloric/BC Components) - Upgrade Substitute:

The MAL215370478E3 is classified as an upgrade substitute. This part maintains Active product status and meets all mandatory electrical and mechanical compatibility requirements. The MAL215370478E3 demonstrates superior ESR performance (8 Ohm @ 100 kHz versus 49.38 Ohm @ 120 Hz for the main part), indicating lower impedance characteristics at higher frequencies. The extended operating temperature range (-55°C ~ 105°C) and higher temperature lifetime rating (2000 Hrs @ 105°C) provide broader thermal operating margins. The part is available in Tape & Reel packaging and maintains ROHS3 compliance with REACH Unaffected status. Height dimension is 0.209" (5.30mm), which is 0.008" lower than the main part, ensuring mechanical compatibility within standard PCB assembly tolerances.

UWJ1V4R7MCL1GB (Nichicon) - Parametric Equivalent Substitute:

The UWJ1V4R7MCL1GB is classified as a parametric equivalent substitute. This part meets all mandatory electrical and mechanical compatibility requirements and maintains identical operating temperature range (-40°C ~ 85°C) and lifetime rating (2000 Hrs @ 85°C) as the main part. However, the UWJ1V4R7MCL1GB carries Obsolete product status, indicating discontinued manufacturing and potential long-term supply constraints. The part is available in Tape & Reel packaging and maintains ROHS3 compliance. REACH Status is listed as REACH Affected, which may introduce regulatory considerations in certain applications or regions. ESR specification is not provided for this part. Height dimension matches the main part at 0.217" (5.50mm).

Selection Guidance:

For new designs or applications requiring long-term component availability, MAL215370478E3 is the preferred substitute, offering Active product status and superior electrical performance characteristics. UWJ1V4R7MCL1GB is suitable only for legacy system maintenance or applications where existing design validation has been completed with this specific part number, given its Obsolete status.

Frequently Asked Questions (FAQ)

Q: Can MAL215370478E3 be used as a direct replacement for 475SML035M in existing designs?

A: Yes. The MAL215370478E3 meets all mandatory electrical specifications (4.7 µF, ±20%, 35 V) and mechanical compatibility requirements (0.157" diameter, 0.169" x 0.169" land pattern, surface mount radial can package). The 0.008" height difference (5.30mm versus 5.50mm) is within standard PCB assembly tolerances and does not affect mechanical fit or electrical performance.

Q: What is the significance of the ESR difference between 475SML035M and MAL215370478E3?

A: The MAL215370478E3 exhibits lower ESR (8 Ohm @ 100 kHz) compared to the main part (49.38 Ohm @ 120 Hz). Lower ESR reduces impedance at higher frequencies, resulting in improved ripple current handling and reduced heat generation. This characteristic makes MAL215370478E3 suitable for applications with higher frequency ripple current requirements.

Q: Why is UWJ1V4R7MCL1GB listed as Obsolete?

A: Obsolete product status indicates that Nichicon has discontinued manufacturing of the UWJ1V4R7MCL1GB. This classification reflects the manufacturer's end-of-life decision and does not indicate a defect or performance issue. Existing inventory may remain available through authorized distributors, but long-term supply cannot be guaranteed.

Q: Are there packaging differences between the main part and substitutes?

A: Yes. The 475SML035M is supplied in Bulk packaging, while both MAL215370478E3 and UWJ1V4R7MCL1GB are supplied in Tape & Reel (TR) format. Tape & Reel packaging is standard for automated assembly processes and does not affect component electrical or mechanical performance.

Q: What does REACH Affected status mean for UWJ1V4R7MCL1GB?

A: REACH Affected status indicates that the component or its manufacturing process may involve substances regulated under the EU REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) directive. This designation requires verification of compliance with specific regional regulations before use in applications subject to REACH requirements. MAL215370478E3 carries REACH Unaffected status, indicating no such regulatory constraints.

Q: Can both substitute parts be used interchangeably in the same application?

A: Both parts satisfy core electrical and mechanical compatibility requirements. However, selection should be based on product status and regulatory requirements. MAL215370478E3 is recommended for new designs due to Active status. UWJ1V4R7MCL1GB is suitable only for legacy applications where design validation has been completed with this specific part.

Q: What is the significance of the temperature rating difference between MAL215370478E3 and the main part?

A: MAL215370478E3 operates across -55°C ~ 105°C with 2000 Hrs lifetime @ 105°C, while 475SML035M operates across -40°C ~ 85°C with 2000 Hrs lifetime @ 85°C. The extended temperature range of MAL215370478E3 provides additional thermal margin for applications operating in elevated temperature environments, though both parts meet the specified 35 V voltage rating across their respective operating ranges.
