Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ECO-S1HP332CA is determined by strict adherence to the following electrical and mechanical parameters:

Critical Parameters (Must Match):

• Capacitance: 3300 µF
• Voltage Rating: 50 V
• Tolerance: ±20%
• Lead Spacing: 0.394" (10.00 mm)
• Package Type: Radial, Can - Snap-In
• Mounting Type: Through Hole
• Polarization: Polar
• Operating Temperature Range: -40°C ~ 85°C

Performance Parameters (Allowable Variation):

• ESR: 100 mOhm @ 120 Hz (substitutes may vary within acceptable limits for the application)
• Lifetime @ Temperature: 3000 Hrs @ 85°C (substitutes meeting or exceeding this specification)
• Physical Dimensions: Diameter and height may vary within snap-in package constraints

All identified substitute parts meet these criteria and maintain functional equivalence for general-purpose applications.

Parameter Comparison

Engineering Selection Recommendations

Direct Replacement (Preferred): SLPX332M050C1P3 provides the closest physical and electrical match to the ECO-S1HP332CA. This part maintains identical capacitance, voltage rating, tolerance, and physical dimensions (25.00 mm diameter × 25.00 mm height). The part is active in production with ROHS3 compliance and REACH unaffected status, ensuring long-term availability and regulatory compliance.

Primary Alternatives: 380LX332M050J012 and 380LX332M050H022 are active Cornell Dubilier products meeting all critical electrical parameters with matching ESR specifications. Both maintain the required 3000-hour lifetime rating and offer ROHS3 compliance. Physical dimension variations require PCB layout verification.

Secondary Alternatives: SLPX332M050A3P3 meets all critical parameters with slightly elevated ESR (141 mOhm). This part is suitable for applications where ESR tolerance permits higher values. 380LX332M050K202 offers ESR of 117 mOhm with reduced ripple current capacity at low frequency (1.7 A @ 120 Hz), requiring thermal performance evaluation for specific applications.

Limited Suitability: B41231B6338M000 from EPCOS - TDK Electronics meets electrical specifications but specifies only 2000 hours lifetime at 85°C, below the original 3000-hour rating. This part is suitable only for applications with reduced lifetime requirements or lower thermal stress conditions.

Frequently Asked Questions (FAQ)

Q: Can SLPX332M050C1P3 be used as a direct drop-in replacement for ECO-S1HP332CA? A: Yes. SLPX332M050C1P3 maintains identical capacitance (3300 µF), voltage rating (50 V), tolerance (±20%), lead spacing (10.00 mm), and physical dimensions (25.00 mm diameter × 25.00 mm height). The part is active in production with current regulatory compliance.

Q: What is the significance of ESR differences among substitute parts? A: ESR (Equivalent Series Resistance) affects ripple current handling and thermal performance. The original ECO-S1HP332CA specifies 100 mOhm @ 120 Hz. Substitutes with higher ESR values (141 mOhm for SLPX series, 117 mOhm for 380LX332M050K202) generate additional heat under ripple current conditions. Selection depends on circuit ripple current requirements and thermal design margins.

Q: Are all substitute parts RoHS compliant? A: All active substitute parts listed (380LX series, SLPX series, and B41231B6338M000) are ROHS3 compliant. The original ECO-S1HP332CA is marked as REACH Affected; all substitutes are REACH Unaffected, providing improved regulatory status for new designs.

Q: What are the physical dimension constraints for PCB layout? A: The original part specifies 25.00 mm diameter and 25.00 mm height. Substitute parts vary: 380LX332M050J012 (25.00 mm × 27.00 mm), 380LX332M050H022 (22.00 mm × 32.00 mm), SLPX332M050A3P3 (22.00 mm × 30.00 mm), and SLPX332M050C1P3 (25.00 mm × 25.00 mm). PCB footprint and clearance requirements must be verified for non-identical dimensions.

Q: Why is the B41231B6338M000 rated for only 2000 hours instead of 3000 hours? A: The B41231B6338M000 from EPCOS - TDK Electronics specifies a different thermal rating profile. This part is suitable for applications with lower thermal stress or where extended lifetime is not required. For applications requiring the full 3000-hour rating, Cornell Dubilier or Panasonic alternatives are recommended.

Q: What is the lead spacing requirement, and do all substitutes meet it? A: Lead spacing of 0.394" (10.00 mm) is a critical parameter for through-hole PCB compatibility. All listed substitute parts maintain this specification, ensuring mechanical compatibility with existing PCB designs.
