Equivalent & Substitute Parts for 476KXM063M

Part Overview

The 476KXM063M is a 47 µF, 63 V aluminum electrolytic capacitor in radial, can package manufactured by Cornell Dubilier / Illinois Capacitor. This component is classified as Active product status and serves general-purpose applications requiring polarized capacitive energy storage and filtering.

Substitute parts become necessary when the primary part experiences inventory constraints, extended lead times, or when design requirements favor alternative manufacturers with enhanced specifications such as extended lifetime ratings or automotive-grade certifications. The substitute parts listed maintain electrical and mechanical compatibility within the defined parameter tolerances for this capacitor category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 476KXM063M is determined by strict adherence to the following core parameters:

Mandatory Matching Parameters:

• Capacitance: 47 µF (exact match required)
• Voltage Rating: 63 V (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)
• Package Type: Radial, Can (exact match required)
• Lead Spacing: 0.138" (3.50mm) (exact match required)
• Case Diameter: 0.315" (8.00mm) (exact match required)
• Mounting Type: Through Hole (exact match required)
• Operating Temperature Range: -55°C to 105°C (exact match required)

Allowable Variation Parameters:

• Height (Seated Max): Variation permitted within PCB layout constraints
• ESR (Equivalent Series Resistance): Lower values acceptable; higher values require circuit validation
• Ripple Current Ratings: Higher values acceptable; lower values require thermal analysis
• Impedance: Lower values acceptable; higher values require circuit validation
• Lifetime @ Temperature: Equal or extended ratings acceptable
• Product Status: Active or Not For New Designs both acceptable for substitution
• Manufacturer Certifications: AEC-Q200 automotive rating acceptable as upgrade path

All three substitute parts meet the mandatory matching criteria and are therefore direct electrical and mechanical equivalents.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: MAL215058479E3 (Vishay Beyschlag/Draloric/BC Components)

The MAL215058479E3 is the preferred substitute for new designs. This part maintains all mandatory electrical and mechanical parameters while offering extended lifetime (4000 Hrs @ 105°C versus 3000 Hrs), lower impedance (342 mOhms), and AEC-Q200 automotive certification. Product status is Active, supporting long-term availability and design continuity.

Secondary Substitute: ELXV630ELL470MH12D (Chemi-Con)

The ELXV630ELL470MH12D provides equivalent performance with Active product status and AEC-Q200 automotive certification. Height dimension is 0.531" (13.50mm), which is 0.019" taller than the primary part. This substitute is suitable when automotive-grade reliability is required and PCB layout accommodates the increased height.

Tertiary Substitute: UPJ1J470MPD (Nichicon)

The UPJ1J470MPD is electrically compatible but carries Not For New Designs product status. This part offers lower impedance (370 mOhms) and is suitable only for legacy system maintenance or replacement applications where design revision is not feasible. Height dimension is 0.492" (12.50mm), which is 0.020" shorter than the primary part.

Frequently Asked Questions (FAQ)

Q: Can MAL215058479E3 be used as a direct replacement for 476KXM063M in existing designs?

A: Yes. The MAL215058479E3 maintains identical capacitance (47 µF), voltage rating (63 V), tolerance (±20%), lead spacing (3.50mm), case diameter (8.00mm), and operating temperature range (-55°C to 105°C). Height variation of ±0.019" is within typical PCB layout tolerances for through-hole radial capacitors. No circuit modifications are required.

Q: What is the significance of the AEC-Q200 certification on substitute parts?

A: AEC-Q200 is an automotive-grade reliability standard. Parts bearing this certification (MAL215058479E3 and ELXV630ELL470MH12D) have undergone enhanced qualification testing. This certification is relevant only if the application requires automotive-grade component reliability. For general-purpose applications, this certification provides no functional advantage.

Q: Why does UPJ1J470MPD carry "Not For New Designs" status?

A: This designation indicates the manufacturer has discontinued active promotion of this part for new circuit designs. While electrically and mechanically compatible, this part should be reserved for legacy system maintenance only. For new designs, select MAL215058479E3 or ELXV630ELL470MH12D.

Q: How do impedance differences affect circuit performance?

A: Lower impedance values (MAL215058479E3 at 342 mOhms, UPJ1J470MPD at 370 mOhms) indicate superior high-frequency filtering characteristics compared to the primary part (810 mOhms). These differences are beneficial in ripple current suppression and noise filtering applications. No circuit redesign is required; lower impedance substitutes provide equal or improved performance.

Q: Are height dimension variations critical for PCB layout?

A: Height variations among the substitute parts range from 0.492" to 0.531" (12.50mm to 13.50mm). Standard PCB design practice accommodates ±0.050" (1.27mm) component height variation. All substitute parts fall within this tolerance. Verify specific PCB clearance requirements if components are mounted near low-profile adjacent components or under conformal coating.

Q: Can these parts be used interchangeably in high-ripple-current applications?

A: Ripple current ratings vary among the parts. The primary 476KXM063M supports 480 mA @ 100 kHz. Substitute parts show lower ripple current specifications (ELXV630ELL470MH12D at 275 mA @ 100 kHz). For applications requiring maximum ripple current handling, verify the substitute part's ripple current rating against circuit requirements before selection.
