ECO-S1KP152CA Equivalent & Substitute Parts

Part Overview

The ECO-S1KP152CA is a 1500 µF, 80 V aluminum electrolytic capacitor in radial, can snap-in package manufactured by Panasonic Electronic Components. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing system maintenance and new design implementations. 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 stable capacitance and low equivalent series resistance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ECO-S1KP152CA is determined by strict equivalence across the following critical parameters:

• Capacitance value: 1500 µF (exact match required)
• Voltage rating: 80 V (exact match required)
• Tolerance: ±20% (exact match required)
• Package type: Radial, Can - Snap-In (exact match required)
• Lead spacing: 0.394" (10.00 mm) (exact match required)
• Mounting type: Through Hole (exact match required)
• Polarization: Polar (exact match required)

All three substitute parts meet these core electrical and mechanical requirements. Variations in ESR, ripple current ratings, physical dimensions (diameter and height), operating temperature range, and product status are secondary considerations that may affect performance characteristics but do not disqualify substitution based on the primary functional parameters.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are active products from Cornell Dubilier Electronics (CDE) and provide functional equivalence to the obsolete ECO-S1KP152CA. Selection among these alternatives depends on specific application constraints:

380LX152M080H022: Maintains identical ESR (177 mOhm @ 120Hz) and lifetime rating (3000 Hrs @ 85°C) as the original part. Physical dimensions differ, with reduced diameter (22.00 mm vs. 25.00 mm) but increased height (32.00 mm vs. 25.00 mm). ROHS3 compliant. Suitable for applications where ESR matching is critical and physical space accommodates the increased height.

SLP152M080C1P3: Offers extended operating temperature range (-40°C to 105°C) and lifetime rating at elevated temperature (3000 Hrs @ 105°C). ESR is higher at 221 mOhm @ 120Hz. Physical dimensions match the original part exactly (0.984" diameter and height). ROHS3 compliant. Suitable for applications requiring higher temperature performance or where physical dimensions must remain unchanged.

SLPX152M080A3P3: Provides intermediate characteristics with higher ESR (221 mOhm @ 120Hz) and standard operating temperature range (-40°C to 85°C). Physical dimensions show reduced diameter (22.00 mm) with increased height (30.00 mm). ROHS3 compliant. Suitable for applications where moderate ESR increase is acceptable and physical space constraints permit dimensional variation.

All substitute parts carry ROHS3 compliance and are currently in active production, ensuring long-term availability.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts interchangeably with the ECO-S1KP152CA?

A: All three substitute parts meet the core electrical and mechanical requirements (1500 µF, 80 V, ±20% tolerance, radial snap-in package, 10.00 mm lead spacing, through-hole mounting). However, physical dimensions and ESR characteristics differ. Verify that your PCB layout accommodates the specific diameter and height of your chosen substitute, and confirm that the ESR value is acceptable for your circuit's ripple current and thermal management requirements.

Q: What is the significance of ESR differences between the main part and substitutes?

A: The ECO-S1KP152CA and 380LX152M080H022 both specify 177 mOhm @ 120Hz, while SLP152M080C1P3 and SLPX152M080A3P3 specify 221 mOhm @ 120Hz. Higher ESR increases heat generation under ripple current conditions. If your application operates at high ripple current or requires minimal thermal dissipation, the lower-ESR options (ECO-S1KP152CA or 380LX152M080H022) are preferred.

Q: Why do physical dimensions vary among parts with identical electrical ratings?

A: Manufacturers optimize can design based on internal construction, terminal configuration, and manufacturing processes. Variations in diameter and height reflect different internal geometries while maintaining the same capacitance, voltage, and tolerance specifications. PCB layout must accommodate the specific dimensions of the selected part.

Q: Is the extended temperature rating of SLP152M080C1P3 beneficial for my application?

A: The SLP152M080C1P3 operates to 105°C with a lifetime rating of 3000 Hrs @ 105°C, compared to 85°C for the other parts. This is beneficial only if your application requires operation above 85°C. For standard applications operating within -40°C to 85°C, the extended rating provides no functional advantage.

Q: Are all substitute parts RoHS compliant?

A: Yes. All three substitute parts are ROHS3 compliant. The original ECO-S1KP152CA does not specify RoHS status. If RoHS compliance is required for your application, all three substitutes satisfy this requirement.

Q: How do I verify physical fit before committing to a substitute part?

A: Obtain the mechanical drawings for your selected substitute part and compare the diameter and height dimensions against your PCB layout and available mounting space. The lead spacing (10.00 mm) is identical across all parts, so through-hole alignment is not a concern.
