Substitute Part Grouping Explanation

Substitution eligibility is determined by strict adherence to the following parameters:

Direct Substitutes maintain identical electrical and mechanical specifications:

Capacitance: 8200 µF (exact match required)
Voltage Rating: 16 V (exact match required)

Case Diameter: 0.866" (22.00 mm)
Package Type: Radial, Can - Snap-In
Mounting Type: Through Hole
Operating Temperature: -40°C to 105°C minimum

Upgrade Substitutes increase voltage rating while maintaining all other critical parameters. These are suitable when higher voltage margin is acceptable:

Capacitance: 8200 µF (exact match required)
Voltage Rating: 25 V or higher (exceeds original 16 V)
Tolerance: ±20% (exact match required)
Lead Spacing: 0.394" (10.00 mm)
Case Diameter: 0.866" (22.00 mm)
Package Type: Radial, Can - Snap-In
Mounting Type: Through Hole

Parametric Equivalents match all critical electrical and mechanical parameters with minor variations in lifetime or ESR specifications:

Capacitance: 8200 µF (exact match required)
Voltage Rating: 16 V (exact match required)
Tolerance: ±20% (exact match required)
Lead Spacing: 0.394" (10.00 mm)
Case Diameter: 0.866" (22.00 mm)
Height: 1.260" (32.00 mm)
Package Type: Radial, Can - Snap-In
Mounting Type: Through Hole

Similar Parts share capacitance and package form factor but differ in voltage rating or thermal specifications. These are not direct substitutes and require circuit validation.

Engineering Selection Recommendations

Direct Substitutes (16 V, 8200 µF, Active Status):

SLP822M016A3P3 (Cornell Dubilier) and 381LX822M016H022 (Cornell Dubilier) are active production parts with identical electrical specifications. Both are ROHS3 compliant. SLP822M016A3P3 features a reduced height of 1.181" compared to the original 1.260", which may provide board layout advantages. 381LX822M016H022 maintains the original height specification.

LGY1C822MELZ30 (Nichicon) and LGU1C822MELZ (Nichicon) are parametric equivalents with extended 5000-hour and 3000-hour lifetime ratings respectively at 105°C, compared to the original 3000-hour specification. Both are ROHS3 compliant and maintain original dimensions.

Upgrade Substitutes (Higher Voltage Rating):

25MXG8200MEFCSN22X30 (Rubycon) and 381LX822M025H022 (Cornell Dubilier) provide 25 V rating while maintaining 8200 µF capacitance and original dimensions. Both are ROHS3 compliant and active production parts. These are suitable for applications where increased voltage margin is required.

Considerations for Similar Parts:

LP822M016A5P3 (Cornell Dubilier) maintains 16 V rating and 8200 µF capacitance but features reduced 1000-hour lifetime at 105°C and increased height of 1.378". This part is suitable only for applications with lower thermal stress requirements.

10VXG8200MEFC22X25 (Rubycon), 35MXG8200MEFCSN22X45 (Rubycon), and 35USG8200MEFCSN22X40 (Rubycon) differ significantly in voltage rating and physical dimensions. These require circuit validation and are not recommended as direct replacements without engineering review.

Frequently Asked Questions (FAQ)

Q: Can SLP822M016A3P3 replace ECO-S1CA822BA directly?

A: Yes. SLP822M016A3P3 maintains identical capacitance (8200 µF), voltage rating (16 V), tolerance (±20%), lead spacing (10.00 mm), and case diameter (22.00 mm). The reduced height of 1.181" versus 1.260" may require PCB layout verification but does not affect electrical performance.

Q: What is the difference between direct substitutes and upgrade substitutes?

A: Direct substitutes maintain the original 16 V voltage rating. Upgrade substitutes increase the voltage rating to 25 V or higher while preserving 8200 µF capacitance and mechanical compatibility. Upgrade substitutes provide additional voltage margin and are suitable when circuit design permits higher voltage components.

Q: Why is LP822M016A5P3 not recommended as a primary substitute?

A: LP822M016A5P3 features a reduced lifetime rating of 1000 hours at 105°C compared to the original 3000 hours, and increased height of 1.378". This part is suitable only for applications with lower thermal stress or where extended height is acceptable.

Q: Are all substitute parts ROHS3 compliant?

A: All active production substitute parts listed are ROHS3 compliant. The original ECO-S1CA822BA is obsolete and ROHS compliance status is not specified.

Q: Can 10VXG8200MEFC22X25 be used as a substitute?

A: No. This part operates at 10 V, which is below the original 16 V rating. Using a lower voltage-rated capacitor in a 16 V circuit creates reliability risk and is not acceptable without circuit redesign.

Q: What is the significance of ESR (Equivalent Series Resistance)?

A: ESR affects ripple current handling and heat generation. The original part specifies 71 mOhm @ 120 Hz. SLP822M016A3P3 and 381LX822M025H022 specify 81 mOhm, which is slightly higher but remains within acceptable operating parameters for general-purpose applications. Parts without specified ESR values require manufacturer consultation for ripple current applications.

Q: Do all substitutes maintain the same lead spacing and case diameter?

A: Yes. All listed substitutes maintain 0.394" (10.00 mm) lead spacing and 0.866" (22.00 mm) case diameter, ensuring mechanical compatibility with existing PCB designs. Height variations exist and must be verified against board clearance requirements.
