Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ECO-S1HP222BA are qualified based on the following electrical and mechanical parameters:

• Capacitance: 2200 µF (exact match required)
• Voltage Rating: 50 V (exact match required)
• Tolerance: ±20% (exact match required)
• Lifetime: 3000 Hrs @ 85°C (exact match required)
• Operating Temperature: -40°C ~ 85°C (exact match required)
• Lead Spacing: 0.394" (10.00 mm) (exact match required)
• Size / Dimension: 0.866" Dia (22.00 mm) (exact match required)
• Package / Case: Radial, Can - Snap-In (exact match required)
• Mounting Type: Through Hole (exact match required)
• Polarization: Polar (exact match required)

All identified substitutes meet these core parameters. Variations in ESR, ripple current specifications, and height within acceptable mechanical tolerances do not disqualify parts from substitution eligibility.

Parameter Comparison

Engineering Selection Recommendations

Both LLS1H222MELZ (Nichicon) and SLPX222M050A1P3 (Cornell Dubilier Electronics) are active product alternatives to the obsolete ECO-S1HP222BA. Selection between these substitutes should be based on the following factors:

Compliance and Regulatory Status: The LLS1H222MELZ and SLPX222M050A1P3 are both ROHS3 compliant and REACH unaffected, providing superior regulatory compliance compared to the original part. Applications requiring REACH compliance should prioritize these active alternatives.

Physical Fit: The LLS1H222MELZ has a maximum seated height of 1.063" (27.00 mm), which exceeds the original part's 0.984" (25.00 mm). The SLPX222M050A1P3 maintains the original height specification of 0.984" (25.00 mm). PCB layouts with height constraints should specify SLPX222M050A1P3.

Electrical Performance: The SLPX222M050A1P3 exhibits higher ESR at 211 mOhm compared to the original 151 mOhm specification. The LLS1H222MELZ does not specify ESR. Applications sensitive to ESR characteristics should evaluate the SLPX222M050A1P3 against circuit requirements.

Availability: All three parts maintain active inventory levels, with 919 units of the original part, 838 units of the Nichicon substitute, and 884 units of the CDE substitute currently in stock.

Frequently Asked Questions (FAQ)

Q: Can LLS1H222MELZ be used as a direct replacement for ECO-S1HP222BA?

A: Yes. The LLS1H222MELZ meets all core electrical and mechanical parameters. The maximum seated height of 1.063" (27.00 mm) is 0.079" (2.00 mm) taller than the original specification. Verify PCB clearance before implementation.

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

A: Both substitutes share identical capacitance, voltage, tolerance, and lifetime specifications. The SLPX222M050A1P3 maintains the original height of 0.984" (25.00 mm) and specifies ESR at 211 mOhm @ 120 Hz. The LLS1H222MELZ is 0.079" (2.00 mm) taller and does not specify ESR.

Q: Are the substitute parts RoHS and REACH compliant?

A: Yes. Both LLS1H222MELZ and SLPX222M050A1P3 are ROHS3 compliant and REACH unaffected, providing improved regulatory compliance over the original ECO-S1HP222BA.

Q: Does the higher ESR of SLPX222M050A1P3 affect circuit performance?

A: The SLPX222M050A1P3 specifies ESR at 211 mOhm @ 120 Hz compared to the original 151 mOhm. Circuit impact depends on application-specific requirements. Evaluate ESR specifications against your circuit design parameters.

Q: Which substitute should be selected for space-constrained applications?

A: The SLPX222M050A1P3 maintains the original height specification of 0.984" (25.00 mm). Select this part for PCB layouts with height constraints.

Q: Are all three parts pin-compatible?

A: Yes. All parts share identical lead spacing of 0.394" (10.00 mm) and radial, can snap-in package configuration, ensuring mechanical compatibility with existing PCB designs.
