Key Parameters

Substitute Part Grouping Explanation

Substitution of the SN102M6R3ST is determined by strict equivalence in the following parameters:

Critical Parameters for Substitution:

• Capacitance value: 1000 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Lead spacing: 0.197" (5.00mm) (exact match required)
• Mounting type: Through Hole (exact match required)
• Package type: Radial, Can (exact match required)
• Operating temperature range: -40°C to 85°C (minimum requirement)
• Polarization: Bi-Polar (exact match required)

Parameters Allowing Variation:

• Voltage rating: May be equal to or greater than 6.3 V
• Lifetime @ 85°C: May be equal to or greater than 1000 hours
• ESR: May vary based on manufacturer design
• Ripple current: May vary based on voltage rating and design

The identified substitute parts meet all critical parameters while offering enhanced voltage ratings and extended operational lifetimes compared to the original component.

Engineering Selection Recommendations

ECE-A1CN102U (Upgrade Substitute): This Panasonic component provides a direct functional upgrade with identical capacitance and tolerance specifications. The 16 V voltage rating exceeds the original 6.3 V requirement, providing additional design margin. The doubled lifetime specification (2000 hours at 85°C versus 1000 hours) extends component reliability. Active product status ensures long-term availability and supply chain continuity. ROHS3 compliance matches the original specification. Case diameter reduction (12.50mm versus 13.00mm) and maintained lead spacing permit direct PCB substitution with minimal layout modification.

ECE-A1AN102X (Similar Substitute): This Panasonic component maintains identical capacitance and tolerance with a 10 V voltage rating, providing adequate margin above the 6.3 V requirement. Lifetime specification matches the upgrade option at 2000 hours at 85°C. Active product status ensures procurement availability. ROHS3 compliance is maintained. Height reduction to 0.787" (20.00mm) from 0.984" (25.00mm) offers space optimization benefits. Case diameter reduction to 12.50mm permits direct substitution. This option is suitable for applications where the reduced height provides mechanical advantage without compromising electrical performance.

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

Frequently Asked Questions (FAQ)

Q: Can ECE-A1CN102U or ECE-A1AN102X be used as direct replacements for SN102M6R3ST?

A: Yes. Both substitute parts maintain identical capacitance (1000 µF), tolerance (±20%), lead spacing (5.00mm), and through-hole mounting configuration. The higher voltage ratings (16 V and 10 V respectively) are compatible with circuits designed for 6.3 V operation. Case diameter reduction from 13.00mm to 12.50mm requires verification of PCB pad spacing but does not affect electrical function.

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

A: ECE-A1CN102U provides the highest voltage rating (16 V) and maintains the original height (25.00mm). ECE-A1AN102X offers a reduced height (20.00mm) with a 10 V voltage rating. Both provide doubled lifetime specifications (2000 hours at 85°C). Selection depends on available PCB space and circuit voltage requirements.

Q: Are there mechanical compatibility concerns with the substitute parts?

A: The case diameter reduction from 13.00mm to 12.50mm requires PCB pad verification. Lead spacing remains constant at 5.00mm, ensuring through-hole compatibility. ECE-A1AN102X height reduction to 20.00mm may require clearance verification in space-constrained applications. Standard PCB design practices accommodate these dimensional variations.

Q: Do the substitute parts meet the same compliance standards?

A: Yes. Both ECE-A1CN102U and ECE-A1AN102X are ROHS3 compliant, matching the original SN102M6R3ST specification. Both are classified as active products with established supply chains.

Q: How do ripple current specifications compare?

A: The original SN102M6R3ST specifies 690 mA ripple current at 120 Hz. ECE-A1CN102U specifies 560 mA at 120 Hz; ECE-A1AN102X specifies 470 mA at 120 Hz. Both substitute parts provide adequate ripple current handling for general-purpose applications. Applications requiring maximum ripple current capacity should reference the detailed electrical specifications of the selected substitute.

Q: What is the significance of the extended lifetime specification?

A: The substitute parts specify 2000 hours at 85°C compared to 1000 hours for the original component. This doubled lifetime rating indicates enhanced reliability and extended operational capability under thermal stress conditions, providing additional design margin for long-term deployment scenarios.
