Substitute Part Grouping Explanation

Substitution for the SN470M010ST is determined by the following critical parameters:

Mandatory Matching Criteria:

• Capacitance: 47 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Bi-Polar (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial, Can (exact match required)
• Lead Spacing: 0.098" (2.50mm) (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (minimum requirement)

Allowable Variation:

• Voltage - Rated: May be equal to or greater than 10 V (higher voltage rating provides backward compatibility)
• Lifetime @ Temp.: May be equal to or greater than 1000 Hrs @ 85°C (extended lifetime is acceptable)
• Physical dimensions (diameter, height): Minor variations within manufacturing tolerances are acceptable if lead spacing and mounting type remain unchanged

The substitute parts listed below meet all mandatory matching criteria and provide equal or superior performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

ECE-A1EN470U (Upgrade Substitute): This Panasonic part provides a 25 V rated voltage compared to the original 10 V specification, delivering enhanced voltage margin for circuit protection. The lifetime rating of 2000 hours at 85°C doubles the original specification, improving long-term reliability. The part maintains active product status with full ROHS3 compliance and REACH unaffected designation, ensuring supply chain continuity and regulatory compliance. Physical dimensions show minor increases (0.248" diameter vs. 0.236", 0.441" height vs. 0.433") that remain within acceptable tolerances for standard through-hole PCB layouts with 2.50mm lead spacing.

ECE-A1CN470U (Similar Substitute): This Panasonic part provides a 16 V rated voltage, offering moderate voltage margin above the original 10 V specification. The lifetime rating of 2000 hours at 85°C doubles the original specification. The part maintains active product status with full ROHS3 compliance and REACH unaffected designation. Physical dimensions match the ECE-A1EN470U variant. This option is suitable for applications where the 25 V rating of the upgrade substitute exceeds design requirements.

Both substitute parts are manufactured by Panasonic Electronic Components, an established supplier with active product lines, ensuring long-term availability and consistent quality standards.

Frequently Asked Questions (FAQ)

Q: Can ECE-A1EN470U or ECE-A1CN470U be used as direct replacements for SN470M010ST?

A: Yes. Both parts match all mandatory electrical and mechanical parameters: 47 µF capacitance, ±20% tolerance, bi-polar polarization, through-hole mounting, radial can package, and 2.50mm lead spacing. The higher voltage ratings (25 V and 16 V respectively) provide backward compatibility with the original 10 V specification.

Q: What is the difference between the two substitute parts?

A: The primary difference is the rated voltage: ECE-A1EN470U is rated at 25 V, while ECE-A1CN470U is rated at 16 V. Both provide identical capacitance, tolerance, temperature range, and lifetime specifications. Selection depends on circuit voltage requirements and design margin preferences.

Q: Will the slightly larger physical dimensions of the substitute parts affect PCB layout?

A: The substitute parts (ECE-A1EN470U and ECE-A1CN470U) have a diameter of 0.248" (6.30mm) compared to the original 0.236" (6.00mm), and height of 0.441" (11.20mm) compared to 0.433" (11.00mm). Lead spacing remains identical at 0.098" (2.50mm). These minor dimensional increases are within standard manufacturing tolerances and should not require PCB redesign for typical through-hole applications.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both ECE-A1EN470U and ECE-A1CN470U are ROHS3 compliant, matching the compliance status of the original SN470M010ST.

Q: Why is the SN470M010ST listed as obsolete?

A: The SN470M010ST is an obsolete product from Cornell Dubilier Electronics. The listed substitute parts from Panasonic Electronic Components are active products with established supply chains and ongoing manufacturing support.

Q: What is the significance of the doubled lifetime rating in the substitute parts?

A: The substitute parts specify 2000 hours at 85°C compared to the original 1000 hours at 85°C. This extended lifetime indicates improved capacitor design and materials, providing greater reliability margin for long-term circuit operation under thermal stress.
