ECO-S1HP153DA Equivalent & Substitute Parts

Part Overview

The ECO-S1HP153DA is a 15000 µF, 50 V aluminum electrolytic capacitor in radial, can snap-in package manufactured by Panasonic Electronic Components. This component is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing system support and procurement planning. The part operates across a temperature range of -40°C to 85°C with a rated lifetime of 3000 hours at 85°C, serving general-purpose applications requiring high-capacitance energy storage.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ECO-S1HP153DA is determined by strict alignment of the following parameters:

• Capacitance value: 15000 µF (exact match required)
• Voltage rating: 50 V (exact match required)
• Tolerance: ±20% (exact match required)
• Package configuration: 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 (minimum requirement)
• Lifetime specification: 3000 Hrs @ 85°C (minimum requirement)

Two substitute parts meet these criteria: LLS1H153MELC (Nichicon, active status) and SLPX153M050H4P3 (Cornell Dubilier Electronics, active status). Both maintain identical electrical ratings and mechanical compatibility with the original part.

Parameter Comparison

Engineering Selection Recommendations

Both LLS1H153MELC and SLPX153M050H4P3 are functionally equivalent to the ECO-S1HP153DA based on electrical and mechanical parameters. Selection between these two active alternatives should consider the following factors:

LLS1H153MELC (Nichicon) offers ROHS3 compliance and REACH unaffected status with higher inventory availability (273,882 pcs). The ESR specification is not provided for this part.

SLPX153M050H4P3 (Cornell Dubilier Electronics) provides ROHS3 compliance, REACH unaffected status, and documented ESR of 31 mOhm at 120 Hz, which is marginally higher than the original part's 28 mOhm specification. Inventory availability is 12,448 pcs.

Both substitutes maintain identical capacitance, voltage rating, tolerance, package configuration, and thermal specifications. The choice between them depends on procurement availability, regulatory compliance requirements for the end application, and ESR performance criticality in the circuit design.

Frequently Asked Questions (FAQ)

Q: Can LLS1H153MELC or SLPX153M050H4P3 be used as direct replacements for ECO-S1HP153DA?

A: Yes. Both parts meet all critical electrical and mechanical parameters: 15000 µF capacitance, 50 V voltage rating, ±20% tolerance, radial snap-in package configuration, 10.00mm lead spacing, and through-hole mounting. Both maintain the required 3000-hour lifetime at 85°C and -40°C to 85°C operating temperature range.

Q: What is the difference in physical dimensions between these parts?

A: The ECO-S1HP153DA has a diameter of 1.181" (30.00mm) and height of 1.969" (50.00mm). The LLS1H153MELC has a diameter of 1.378" (35.00mm) and height of 1.850" (47.00mm). The SLPX153M050H4P3 has a diameter of 1.378" (35.00mm) and height of 1.772" (45.00mm). Physical layout verification is required before substitution to confirm PCB clearance.

Q: Are there compliance differences between the substitute parts?

A: The original ECO-S1HP153DA is REACH Affected. Both substitute parts (LLS1H153MELC and SLPX153M050H4P3) are REACH Unaffected and ROHS3 Compliant, providing improved regulatory alignment for new designs and systems subject to environmental compliance requirements.

Q: How do the ESR specifications compare?

A: The ECO-S1HP153DA specifies 28 mOhm ESR at 120 Hz. The SLPX153M050H4P3 specifies 31 mOhm at 120 Hz. The LLS1H153MELC does not provide ESR specification. For applications where ESR performance is critical, the SLPX153M050H4P3 provides documented performance data within acceptable tolerance of the original part.

Q: What inventory considerations apply to these substitutes?

A: The ECO-S1HP153DA (obsolete) has 739 pcs available. The LLS1H153MELC (active) has 273,882 pcs in stock. The SLPX153M050H4P3 (active) has 12,448 pcs in stock. For long-term procurement planning, the active-status parts provide superior supply chain continuity.
