Key Parameters

Substitute Part Grouping Explanation

Substitution of the ECO-S2HP820CA is determined by strict electrical and mechanical compatibility criteria:

Critical Matching Parameters:

• Capacitance value: 82 µF (exact match required)
• Voltage rating: 500 V (minimum requirement; higher ratings acceptable)
• Tolerance: ±20% (standard industrial tolerance)
• Package type: Radial, Can - Snap-In (mechanical fit requirement)
• Lead spacing: 0.394" (10.00 mm) (PCB footprint compatibility)
• Mounting type: Through Hole (assembly process compatibility)
• Polarization: Polar (electrical polarity requirement)

Performance Parameters (allowable variance):

• ESR: Substitute values within ±25% of original specification are acceptable for general-purpose applications
• Ripple current ratings: Substitute must meet or exceed the original specification
• Lifetime: Substitute must meet or exceed 3000 hours @ 85°C
• Operating temperature range: Must encompass -25°C ~ 85°C minimum

The 380LX820M500K012 from Cornell Dubilier Electronics meets all critical matching parameters and performance requirements for direct substitution.

Engineering Selection Recommendations

The 380LX820M500K012 (Cornell Dubilier Electronics, 380LX series) is a qualified substitute for the obsolete ECO-S2HP820CA based on the following engineering criteria:

Electrical Compatibility: All critical electrical parameters match or exceed the original specification. Capacitance, voltage rating, tolerance, and lifetime are identical. ESR variance of +21.4% remains within acceptable industrial tolerance for general-purpose aluminum electrolytic capacitors. Ripple current performance meets or exceeds the original specification across frequency ranges.

Mechanical Compatibility: Lead spacing (0.394" / 10.00 mm) and package type (Radial, Can - Snap-In) are identical, ensuring PCB footprint compatibility and assembly process compatibility. Physical dimensional differences (can diameter and height) do not affect electrical function or mounting integrity for through-hole applications.

Compliance & Availability: The 380LX820M500K012 is active product status with ROHS3 compliance and REACH unaffected designation. Current inventory availability (1317 pcs) supports production and maintenance requirements.

Application Suitability: Both capacitors are rated for general-purpose applications with identical operating temperature ranges (-25°C ~ 85°C) and thermal lifetime specifications (3000 Hrs @ 85°C), confirming functional equivalence for the intended use case.

Frequently Asked Questions (FAQ)

Q: Can the 380LX820M500K012 be used as a direct replacement for the ECO-S2HP820CA?

A: Yes. The substitute part matches all critical electrical and mechanical parameters: 82 µF capacitance, 500 V voltage rating, ±20% tolerance, identical lead spacing (10.00 mm), and snap-in through-hole mounting. ESR performance is within acceptable variance for general-purpose applications.

Q: What is the significance of the physical dimension differences between the two parts?

A: The ECO-S2HP820CA has a 25.00 mm diameter can with 30.00 mm height, while the 380LX820M500K012 has a 30.00 mm diameter can with 27.00 mm height. These dimensional differences do not affect electrical performance or PCB footprint compatibility, as lead spacing remains identical at 10.00 mm. Physical clearance in the application enclosure should be verified during integration.

Q: Are there any compliance or certification differences between the original and substitute?

A: The original ECO-S2HP820CA is obsolete product status. The substitute 380LX820M500K012 is active product with ROHS3 compliance and REACH unaffected designation, providing better long-term availability and regulatory alignment for new designs and ongoing production.

Q: What is the acceptable ESR variance for substitution?

A: The substitute part exhibits ESR of 2.455 Ohm @ 120Hz compared to the original 2.022 Ohm @ 120Hz, representing a +21.4% variance. This variance is within acceptable industrial tolerance for aluminum electrolytic capacitors in general-purpose applications and does not compromise circuit performance.

Q: How do ripple current ratings compare?

A: The substitute meets or exceeds ripple current specifications. At 120 Hz, the substitute provides 900 mA versus the original 880 mA. High-frequency ripple current performance is comparable across the specified frequency ranges, confirming thermal and electrical stability equivalence.

Q: What should be verified before implementing the substitute in production?

A: Verify physical clearance in the application enclosure due to dimensional differences. Confirm that the circuit design does not require the specific ESR characteristics of the original part. Validate that lead spacing and snap-in mounting compatibility align with PCB design and assembly equipment specifications.
