Key Parameters

Substitute Part Grouping Explanation

Substitution for the ECO-S1HP103EA is determined by strict equivalence across the following parameters:

• Capacitance: 10000 µF (exact match required)
• Voltage Rating: 50 V (exact match required)
• Tolerance: ±20% (exact match required)
• Package Type: Radial, Can - Snap-In (exact match required)
• Mounting Type: Through Hole (exact match required)
• Lead Spacing: 0.394" (10.00mm) (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Polarization: Polar (exact match required)

All substitute parts listed meet these core electrical and mechanical requirements. Variations in physical dimensions (diameter and height), ESR values, ripple current ratings, and lifetime specifications are permitted within the scope of functional equivalence, provided the part maintains the same electrical performance envelope for the intended application.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are active products with current manufacturing status, eliminating obsolescence risk associated with the ECO-S1HP103EA. Selection among available substitutes depends on physical space constraints within the application:

Direct Dimensional Match: SLPX103M050H5P3 provides the closest dimensional profile to the original part (1.378" diameter × 1.378" height), minimizing PCB layout modifications.

Compact Footprint Options: 380LX103M050K042 and SLPX103M050E7P3 offer reduced diameter dimensions (1.181" and 1.181" respectively) for space-constrained applications, with acceptable height variations.

Tall Profile Option: 380LX103M050J052 features a compact 0.984" diameter with extended 2.047" height, suitable for vertical mounting configurations.

Compliance Considerations: All CDE (Cornell Dubilier Electronics) substitutes carry ROHS3 compliance certification. The EPCOS part (B41231B6109M000) also maintains ROHS3 compliance. All parts are classified as REACH Unaffected or REACH Affected, consistent with industrial component standards.

Performance Trade-offs: ESR values range from 36 mOhm (original) to 46 mOhm (SLPX series), representing acceptable variation for general-purpose applications. The EPCOS part specifies 2000-hour lifetime at 85°C versus 3000 hours for alternatives; this reduction is acceptable only if application duty cycle permits.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitutes interchangeably with the ECO-S1HP103EA?

A: All listed parts meet the core electrical specifications (10000 µF, 50 V, ±20% tolerance) and package requirements (radial snap-in, through-hole, 10mm lead spacing). Physical dimensions vary; verify that the selected substitute fits within available PCB space before implementation.

Q: What is the significance of ESR differences between parts?

A: ESR (Equivalent Series Resistance) affects ripple current handling and heat dissipation. The original part specifies 36 mOhm at 120 Hz. Substitutes range from 40 mOhm to 46 mOhm. Higher ESR values result in slightly increased heat generation under ripple current conditions. For applications with high ripple current demands, select parts with lower ESR values (380LX series at 40 mOhm).

Q: Does the lifetime specification difference matter?

A: The original part and most substitutes specify 3000 hours at 85°C. The EPCOS part (B41231B6109M000) specifies 2000 hours. This difference is relevant only for applications requiring extended operational life at elevated temperatures. For standard industrial applications with typical thermal management, both specifications are acceptable.

Q: Are there RoHS compliance concerns?

A: All active substitutes carry ROHS3 compliance certification, meeting current environmental and regulatory requirements. The original Panasonic part is obsolete and may not carry current compliance documentation.

Q: Which substitute offers the best dimensional compatibility?

A: SLPX103M050H5P3 matches the original diameter (1.378") and provides identical height (1.378"), requiring minimal or no PCB layout modification. This part is recommended for direct replacement in existing designs.

Q: Can I use the EPCOS part as a substitute?

A: Yes, the B41231B6109M000 meets all core electrical and mechanical requirements. However, verify that the 2000-hour lifetime specification aligns with your application requirements, as this is lower than the original 3000-hour rating.
