477SAK010M Aluminum Electrolytic Capacitor - Equivalent & Substitute Parts

Part Overview

The 477SAK010M is a 470 µF, 10 V aluminum electrolytic capacitor manufactured by Cornell Dubilier / Illinois Capacitor in the SAK series. This radial, through-hole component is designed for general-purpose applications requiring stable capacitance and reliable performance across extended operating temperatures. The part maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified to provide alternative sourcing options when the primary part becomes unavailable or when application requirements necessitate enhanced electrical or thermal characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 477SAK010M is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Capacitance: 470 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial, Can (exact match required)
• Lead Spacing: 3.50 mm (exact match required)
• Case Diameter: 8.00 mm (exact match required)
• Height - Seated (Max): 10.50 mm (exact match required)

Allowable Parameter Variations:

• Voltage - Rated: Substitute must equal or exceed 10 V
• Operating Temperature Range: Substitute must encompass or exceed -40°C ~ 85°C
• Lifetime @ Temperature: Substitute must meet or exceed 2000 Hrs @ 85°C
• ESR: Substitute may differ if electrical performance remains acceptable
• Ripple Current: Substitute may differ if application requirements are satisfied

The substitute part 16WXA470MEFC8X9 (Rubycon WXA series) meets all mandatory matching parameters and provides enhanced electrical and thermal characteristics within allowable variation ranges.

Engineering Selection Recommendations

477SAK010M (Cornell Dubilier / Illinois Capacitor SAK Series)

Selection criteria: General-purpose applications operating within -40°C to 85°C temperature range with 10 V maximum voltage requirement. Active product status ensures continued availability and manufacturing support. RoHS3 compliance and unlimited moisture sensitivity rating provide regulatory alignment for standard industrial and consumer applications.

16WXA470MEFC8X9 (Rubycon WXA Series)

Selection criteria: Applications requiring extended operating temperature range (-55°C to 105°C) or higher voltage margin (16 V rated). AEC-Q200 automotive qualification indicates enhanced reliability screening and manufacturing controls. RoHS3 compliance maintained. Substitute selection appropriate when primary part unavailability occurs or when application thermal environment exceeds 85°C operating specification. Note: Ripple current rating at 120 Hz is 310 mA compared to 360 mA for primary part; verify application ripple current requirement does not exceed 310 mA at 120 Hz.

Both parts maintain identical physical footprint, lead spacing, and mounting configuration, ensuring direct PCB compatibility without layout modification.

Frequently Asked Questions (FAQ)

Q: Can the 16WXA470MEFC8X9 be used as a direct replacement for the 477SAK010M in all applications?

A: Direct replacement is possible from a physical and electrical standpoint due to identical capacitance, tolerance, case dimensions, and lead spacing. However, the ripple current rating at 120 Hz differs (310 mA vs. 360 mA). Verify that your application's ripple current requirement does not exceed 310 mA at 120 Hz before substitution.

Q: What is the significance of the voltage rating difference (10 V vs. 16 V)?

A: The 16 V rated substitute provides higher voltage margin and is electrically compatible in 10 V applications. Higher voltage rating does not negatively impact performance in lower voltage circuits. This characteristic makes the substitute suitable for applications where voltage headroom is beneficial.

Q: Are there any compliance or certification differences between these parts?

A: Both parts are RoHS3 compliant and REACH unaffected. The substitute part carries AEC-Q200 automotive qualification, indicating additional reliability screening. Both maintain unlimited moisture sensitivity rating (MSL 1).

Q: Do these parts have identical physical dimensions?

A: Yes. Both parts share identical case diameter (8.00 mm), height (10.50 mm maximum seated), and lead spacing (3.50 mm). PCB footprint and mounting hole spacing are identical, requiring no layout changes for substitution.

Q: What is the operating temperature range difference, and does it matter for my application?

A: The primary part operates -40°C to 85°C; the substitute operates -55°C to 105°C. If your application operates within the primary part's range, both are suitable. If your application requires operation above 85°C or below -40°C, the substitute is required.

Q: How do the lifetime specifications compare?

A: Both parts specify 2000 hours lifetime at their respective rated temperatures (85°C for primary, 105°C for substitute). The substitute's higher temperature rating indicates equivalent or superior reliability at elevated temperatures.

Q: Is the ESR specification critical for substitution?

A: ESR (Equivalent Series Resistance) affects ripple current handling and heat generation. The primary part specifies 847 mOhm @ 120 Hz. The substitute does not provide ESR specification in available data. Verify ESR performance through manufacturer datasheet if ESR-sensitive applications require specific impedance characteristics.
