Substitute Part Grouping Explanation

Substitution eligibility for the ECO-S1KA152CA is determined by strict equivalence across the following parameters:

Capacitance: 1500 µF (exact match required)
Tolerance: ±20% (exact match required)
Voltage Rating: 80 V (exact match required)
Package Type: Radial, Can - Snap-In (exact match required)
Mounting Type: Through Hole (exact match required)
Lead Spacing: 0.394" (10.00mm) (exact match required)
Physical Dimensions: 0.984" Dia × 1.260" Height (exact match required)
Operating Temperature: -40°C ~ 105°C (exact match required)
Polarization: Polar (exact match required)

All substitute parts listed meet these core electrical and mechanical parameters. Secondary parameters such as ESR, ripple current ratings, and lifetime specifications may vary within acceptable engineering tolerances for general-purpose applications.

Engineering Selection Recommendations

All listed substitute parts satisfy the core electrical and mechanical requirements for direct replacement of the ECO-S1KA152CA. Selection among active alternatives should be based on the following criteria:

For RoHS3 Compliance Requirements: The 80VXG1500MEFCSN25X30 (Rubycon), B41252B158M (EPCOS - TDK), and 381LX152M080J022 (CDE) are ROHS3 compliant. The 80VXG1500MEFC25X30 (Rubycon) is RoHS non-compliant.

For Extended Lifetime: The 80VXG1500MEFC25X30 and 80VXG1500MEFCSN25X30 (both Rubycon VXG series) offer 5000 hours at 105°C, compared to 3000 hours for the original part and 2000 hours for the B41252B158M.

For Dimensional Tolerance: The B41252B158M has a diameter of 1.000" (25.40mm) versus 0.984" (25.00mm) for all other parts. This minor dimensional difference may affect board layout in space-constrained applications.

For Inventory Availability: All substitute parts are currently in stock with active product status, ensuring supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the 80VXG1500MEFC25X30 be used as a direct replacement for the ECO-S1KA152CA?

A: Yes. Both parts share identical capacitance (1500 µF), voltage rating (80 V), tolerance (±20%), package type (radial snap-in), and physical dimensions. The Rubycon part offers extended lifetime (5000 hours vs. 3000 hours at 105°C) and is currently in active production.

Q: What is the difference between 80VXG1500MEFC25X30 and 80VXG1500MEFCSN25X30?

A: Both are Rubycon VXG series parts with identical electrical specifications and physical dimensions. The primary difference is RoHS compliance: 80VXG1500MEFCSN25X30 is ROHS3 compliant, while 80VXG1500MEFC25X30 is RoHS non-compliant. Both offer 5000-hour lifetime at 105°C.

Q: Is the B41252B158M suitable for applications with tight PCB layout constraints?

A: The B41252B158M has a diameter of 1.000" (25.40mm) compared to 0.984" (25.00mm) for other substitutes. This 0.016" difference may impact board layout. Verify PCB footprint clearances before selection.

Q: Does the 381LX152M080J022 offer any advantages over other substitutes?

A: The 381LX152M080J022 (CDE) matches the original part's 3000-hour lifetime specification and is ROHS3 compliant. It maintains identical physical dimensions and electrical parameters, making it a direct functional equivalent with improved compliance status.

Q: Are all substitute parts suitable for general-purpose applications?

A: Yes. All listed substitutes are rated for general-purpose applications and operate across the same temperature range (-40°C to 105°C) as the original ECO-S1KA152CA.
