Key Parameters

Substitute Part Grouping Explanation

Substitution of the SH471M063ST is determined by strict equivalence across the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Capacitance value: 470 µF (exact match required)
• Tolerance: ±20% (matching tolerance band)
• Voltage rating: 63 V (minimum acceptable rating)
• Polarization: Polar (electrolytic type)

Mechanical Equivalence Criteria:

• Lead spacing: 7.50 mm (0.295 inches)
• Mounting type: Through Hole
• Package type: Radial, Can

Compliance Criteria:

• RoHS3 compliance status
• ECCN and HTSUS classification alignment

The substitute part 477KXM063MQV meets all electrical and mechanical equivalence requirements. Both parts share identical capacitance, tolerance, voltage rating, lead spacing, and mounting configuration. The substitute maintains RoHS3 compliance and identical trade classification codes.

Parameter Comparison

Engineering Selection Recommendations

The 477KXM063MQV is a direct electrical substitute for the SH471M063ST based on matching capacitance, tolerance, voltage rating, and lead spacing. Both components are RoHS3 compliant and share identical ECCN and HTSUS classifications, ensuring regulatory and trade compliance equivalence.

The substitute part offers performance advantages over the main part: extended lifetime (5000 hours versus 2000 hours at 105°C), expanded operating temperature range (-55°C to 105°C versus -40°C to 105°C), and higher ripple current ratings at both low and high frequencies. These enhancements provide improved reliability margins in thermal and electrical stress conditions.

Physical dimensions differ between the two parts. The substitute (477KXM063MQV) has a larger diameter (16.00 mm versus 13.00 mm) and greater height (26.50 mm versus 25.00 mm). PCB layout verification is required to confirm that the substitute component fits within available mounting space and clearance constraints. Lead spacing remains identical at 7.50 mm, ensuring through-hole compatibility with existing PCB footprints.

The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity compared to the obsolete main part.

Frequently Asked Questions (FAQ)

Q: Can the 477KXM063MQV be used as a direct replacement for the SH471M063ST?

A: Yes, the 477KXM063MQV is electrically and mechanically compatible for through-hole mounting applications. Both parts have identical capacitance (470 µF), tolerance (±20%), voltage rating (63 V), and lead spacing (7.50 mm). Physical dimensions differ; verify PCB layout clearance before substitution.

Q: What are the key differences between these two parts?

A: The substitute part (477KXM063MQV) provides extended lifetime (5000 hours at 105°C versus 2000 hours), wider operating temperature range (-55°C to 105°C versus -40°C to 105°C), and higher ripple current ratings. The substitute has a larger can diameter (16.00 mm versus 13.00 mm) and greater height (26.50 mm versus 25.00 mm). ESR is slightly higher (352.7 mOhm versus 280 mOhm at 120 Hz).

Q: Is the substitute part RoHS compliant?

A: Yes, the 477KXM063MQV is RoHS3 compliant, matching the compliance status of the SH471M063ST.

Q: Will the substitute part fit in the same PCB footprint?

A: Lead spacing is identical (7.50 mm), so the through-hole mounting footprint is compatible. However, the substitute has larger physical dimensions (diameter and height). Verify that the PCB layout provides sufficient clearance above and around the component mounting area.

Q: Why is the main part obsolete?

A: The SH471M063ST is classified as obsolete by the manufacturer. The 477KXM063MQV is the active equivalent in the Cornell Dubilier / Illinois Capacitor product line, ensuring continued availability and manufacturing support.

Q: Are there any electrical performance trade-offs with the substitute?

A: The substitute has slightly higher ESR (352.7 mOhm versus 280 mOhm at 120 Hz). In applications sensitive to ESR, this difference should be evaluated against the application's ripple current and thermal requirements. The substitute's higher ripple current ratings and extended lifetime generally offset this minor ESR increase.
