ECO-S1KP102BA Equivalent & Substitute Parts

Part Overview

The ECO-S1KP102BA is a 1000 µF, 80 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 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 stable capacitance and low equivalent series resistance.

Substitute Part Grouping Explanation

Substitution eligibility for the ECO-S1KP102BA is determined by strict alignment of the following parameters:

Capacitance: 1000 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)
Diameter: 0.866" (22.00 mm) (exact match required)
Mounting Type: Through Hole (exact match required)
Polarization: Polar (exact match required)

The identified substitute parts meet all mandatory electrical and mechanical parameters. Variations in height, ESR characteristics, lifetime ratings at different temperatures, and operating temperature upper limits do not disqualify substitution when the core parameters align. Product status (active vs. obsolete) and compliance certifications are secondary considerations for component selection.

Engineering Selection Recommendations

Both B41252A0108M000 and SLP102M080A1P3 are qualified substitutes for the obsolete ECO-S1KP102BA based on matching electrical and mechanical specifications.

B41252A0108M000 (EPCOS - TDK Electronics): This part is active in production and ROHS3 compliant. The primary dimensional difference is increased height (1.260" vs. 0.984"), which requires verification against available board space. ESR is not specified in available documentation. Lifetime rating of 2000 hours at 105°C provides extended temperature operation compared to the original part.

SLP102M080A1P3 (Cornell Dubilier Electronics): This part is active in production and ROHS3 compliant. Physical dimensions match the original part exactly, including height. ESR of 332 mOhm at 120 Hz is slightly higher than the original 265 mOhm. Lifetime rating of 3000 hours at 105°C matches the original part's hour rating while extending maximum operating temperature.

Selection between these substitutes depends on specific application constraints: board space availability, ESR sensitivity, and required operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can B41252A0108M000 be used if the original PCB layout has limited vertical clearance?

A: No. The B41252A0108M000 has a seated height of 1.260" (32.00 mm), compared to 0.984" (25.00 mm) for the ECO-S1KP102BA. If vertical space is constrained, SLP102M080A1P3 maintains the original height specification.

Q: Are both substitute parts suitable for applications operating at temperatures above 85°C?

A: Both substitute parts extend the maximum operating temperature to 105°C, providing improved thermal margin compared to the original part's 85°C limit. This is a secondary benefit and does not affect substitution eligibility for applications within the original temperature range.

Q: What is the significance of the ESR difference between ECO-S1KP102BA and SLP102M080A1P3?

A: The ECO-S1KP102BA specifies 265 mOhm ESR at 120 Hz, while SLP102M080A1P3 specifies 332 mOhm at 120 Hz. This 25% increase in ESR may affect ripple current handling and heat dissipation in applications with high AC current demands. Applications with strict ESR requirements should evaluate this parameter against circuit specifications.

Q: Do the substitute parts require any PCB layout modifications?

A: Lead spacing (0.394" / 10.00 mm) and diameter (0.866" / 22.00 mm) are identical across all three parts. PCB footprints require no modification. Only the B41252A0108M000 requires clearance verification due to increased height.

Q: Are both substitute parts available in the same packaging format?

A: Both substitute parts are supplied in bulk packaging, whereas the original part packaging is not specified. Confirm packaging requirements with your procurement department if tape-and-reel or other specific formats are required.
