Substitute Part Grouping Explanation

Substitution eligibility for the ECO-S2GA101CA is determined by strict adherence to the following parameters:

Capacitance: 100 µF (exact match required)
Voltage Rating: 400 V (exact match required)
Tolerance: ±20% (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)
Polarization: Polar (exact match required)

All substitute parts listed meet these core electrical and mechanical parameters. Variations in ESR, ripple current ratings, lifetime specifications, and operating temperature ranges do not disqualify substitution when the above parameters align. Substitute parts are grouped by manufacturer and product status to facilitate selection based on availability and design phase requirements.

Engineering Selection Recommendations

For Active Production and New Designs:

Select from parts with Active product status: 400MXG100MEFCSN20X30 (Rubycon), B43505A9107M002, B43505A9107M007, B43505A9107M60, B43505A9107M67, B43505A9107M80, B43505A9107M82, B43505A9107M87 (all EPCOS - TDK Electronics), or LGR2G101MELA30 (Nichicon). These parts are supported for ongoing production and design integration.

For Legacy System Support:

B43505A9107M000 carries "Not For New Designs" status and is suitable only for replacement in existing systems where the original ECO-S2GA101CA is no longer available.

Compliance Considerations:

EPCOS - TDK Electronics B43505 series parts and Nichicon LGR2G101MELA30 carry RoHS3 compliance certification. Rubycon 400MXG100MEFCSN20X30 is RoHS3 compliant. All substitute parts are REACH unaffected or REACH affected as specified, with ECCN classification EAR99 and HTSUS code 8532.22.0040 matching the original part.

Dimensional Compatibility:

The Rubycon 400MXG100MEFCSN20X30 features a reduced diameter of 0.787" (20.00mm) compared to the original 0.984" (25.00mm). This dimensional difference may affect board layout and mechanical fit. EPCOS - TDK Electronics B43505A9107M80, B43505A9107M82, and B43505A9107M87 have a maximum seated height of 1.268" (32.20mm) versus 1.260" (32.00mm) for other variants, representing a minor tolerance variation.

Frequently Asked Questions (FAQ)

Q: Can I use 400MXG100MEFCSN20X30 as a direct replacement for ECO-S2GA101CA?

A: Yes, electrically and mechanically. The 400MXG100MEFCSN20X30 meets all core substitution parameters: 100 µF capacitance, 400 V rating, ±20% tolerance, radial snap-in package, and 10.00mm lead spacing. However, its reduced diameter of 0.787" (20.00mm) versus the original 0.984" (25.00mm) requires verification of board layout clearance and mechanical mounting constraints.

Q: What is the difference between the various B43505A9107M variants?

A: All B43505A9107M variants (M000, M002, M007, M60, M67, M80, M82, M87) share identical electrical specifications: 100 µF, 400 V, ±20% tolerance, 5000-hour lifetime at 105°C, and 880 mOhm ESR at 100 Hz. Variants M80, M82, and M87 have a maximum seated height of 1.268" (32.20mm) compared to 1.260" (32.00mm) for M000, M002, M007, and M60. The suffix designations reflect manufacturing date codes or packaging variants. M002 and M007 are Active status; M000 is Not For New Designs.

Q: Does LGR2G101MELA30 offer advantages over other substitutes?

A: LGR2G101MELA30 provides extended lifetime of 10000 hours at 105°C compared to 3000 hours for the original ECO-S2GA101CA and 5000 hours for EPCOS - TDK Electronics variants. This extended rating may benefit applications requiring higher reliability margins. Dimensional specifications match the original part exactly.

Q: Are all substitute parts RoHS compliant?

A: EPCOS - TDK Electronics B43505 series and Nichicon LGR2G101MELA30 are RoHS3 compliant. Rubycon 400MXG100MEFCSN20X30 is RoHS3 compliant. All parts carry REACH unaffected or REACH affected status as documented in their specifications.

Q: Can I use a substitute with a lower operating temperature minimum?

A: The original ECO-S2GA101CA operates from -25°C to 105°C. EPCOS - TDK Electronics B43505 series parts operate from -40°C to 105°C, providing extended low-temperature capability. This represents an enhancement and does not restrict substitution. Rubycon and Nichicon parts maintain the -25°C minimum, matching the original specification.

Q: What is the significance of the different ripple current ratings?

A: Ripple current ratings are provided for reference but do not determine substitution eligibility. The original part specifies 690 mA at 120 Hz and 966 mA at 100 kHz. Substitute parts vary in these ratings based on design differences. Selection should confirm that the substitute's ripple current rating meets or exceeds the application requirement.
