Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SN471M010ST are identified based on the following allowable parameters for aluminum electrolytic capacitors in this category:

Critical matching parameters:

• Capacitance: 470 µF (exact match required)
• Tolerance: ±20% (identical tolerance class)
• Lead Spacing: 0.197" (5.00mm) (mechanical compatibility)
• Package / Case: Radial, Can (form factor match)
• Mounting Type: Through Hole (circuit board compatibility)
• Operating Temperature: -40°C ~ 85°C (thermal range compatibility)
• Polarization: Bi-Polar (functional equivalence)

Allowable variation parameters:

• Voltage - Rated: Can be equal to or higher than 10 V
• ESR: Variations acceptable within active product lines
• Lifetime @ Temp.: Variations acceptable with active product status
• Ripple Current: Variations acceptable within electrical specifications
• Case Diameter: Minor variations permitted (within manufacturing tolerance)
• Manufacturer: Different qualified manufacturers acceptable

The two Panasonic substitute parts (ECE-A1EN471U and ECE-A1CN471U) meet all critical matching parameters and represent active product alternatives with enhanced specifications.

Parameter Comparison

Engineering Selection Recommendations

ECE-A1EN471U (Upgrade Substitute): This Panasonic substitute provides a voltage upgrade from 10 V to 25 V while maintaining the 470 µF capacitance and ±20% tolerance. The component features doubled lifetime specification (2000 Hrs @ 85°C versus 1000 Hrs), indicating enhanced reliability for extended operational life. Product status is active with full ROHS3 compliance. The case diameter is slightly smaller (0.492" vs 0.512"), but lead spacing and height are identical. This part is suitable for direct substitution in applications where voltage headroom and reliability enhancement are beneficial.

ECE-A1CN471U (Similar Substitute): This Panasonic alternative matches the SN471M010ST in capacitance and tolerance with a rated voltage of 16 V, providing a moderate voltage upgrade. Lifetime specification is doubled (2000 Hrs @ 85°C). Product status is active with full ROHS3 compliance. The case diameter is noticeably smaller (0.394" vs 0.512"), which may present space considerations in compact layouts. Lead spacing and height are identical. This part is suitable for substitution when component footprint is a primary design constraint and moderate voltage headroom is sufficient.

Both substitute parts are manufactured by Panasonic Electronic Components, a qualified supplier for aluminum electrolytic capacitors, and both carry active product status ensuring continued availability.

Frequently Asked Questions (FAQ)

Q: Can ECE-A1EN471U or ECE-A1CN471U be used in place of SN471M010ST? A: Yes. Both Panasonic parts are direct substitutes matching all critical parameters: 470 µF capacitance, ±20% tolerance, 0.197" (5.00mm) lead spacing, radial can package, through-hole mounting, and -40°C ~ 85°C operating temperature range.

Q: What are the differences between the two Panasonic alternatives? A: The primary differences are rated voltage (25 V for ECE-A1EN471U versus 16 V for ECE-A1CN471U) and case diameter (0.492" versus 0.394"). Both offer doubled lifetime specifications compared to the original SN471M010ST. Lead spacing and height are identical for both.

Q: Why is the case diameter smaller on ECE-A1CN471U? A: The ECE-A1CN471U uses a smaller diameter can while maintaining the same capacitance, tolerance, and voltage specifications. This is a standard design practice allowing component miniaturization. Lead spacing remains unchanged, ensuring through-hole mounting compatibility.

Q: Are both substitutes ROHS3 compliant? A: Yes. ECE-A1EN471U and ECE-A1CN471U are both ROHS3 compliant, matching the compliance status of the original SN471M010ST.

Q: What is the advantage of selecting the 25 V ECE-A1EN471U over the 16 V ECE-A1CN471U? A: The ECE-A1EN471U provides higher voltage headroom (25 V vs 16 V), which offers additional design margin and protection against overvoltage transients. This part is preferred when voltage stress margin is a design consideration.

Q: Both substitutes show 2000 Hrs lifetime versus 1000 Hrs for the original. What does this mean? A: The lifetime specification indicates the number of hours at 85°C before the capacitor reaches 80% of its initial capacitance. The Panasonic substitutes feature extended lifetime ratings, indicating enhanced long-term reliability and reduced degradation under thermal stress.

Q: Can I use these parts interchangeably in the same circuit board? A: Yes, provided your circuit accommodates the case diameter variations. The ECE-A1CN471U has a noticeably smaller diameter (0.394" vs 0.512"), which may require verification of available board space. Lead spacing and height are identical for all three parts.
