Key Parameters

Substitute Part Grouping Explanation

Substitution of the B41002A3156M is determined by the following critical parameters:

• Capacitance Value: 15 µF (exact match required)
• Voltage Rating: Minimum 10 V (higher ratings acceptable for backward compatibility)
• Tolerance: ±20% (standard tolerance for general purpose applications)
• Package / Case: Radial, Can with Through Hole mounting
• Lead Spacing: 0.059" (1.50 mm) for PCB compatibility
• Physical Dimensions: 0.157" diameter × 0.315" height maximum for mechanical fit
• Polarization: Polar (electrolytic capacitor type)

The EEA-FC1C150 from Panasonic Electronic Components meets all substitution criteria with enhanced performance characteristics including higher voltage rating (16 V), extended temperature range (-55°C ~ 105°C), and improved ripple current handling.

Parameter Comparison

Engineering Selection Recommendations

The EEA-FC1C150 is a direct substitute for the obsolete B41002A3156M. Both components are ROHS3 compliant and share identical physical dimensions and lead spacing, ensuring PCB compatibility without layout modifications.

The Panasonic EEA-FC1C150 offers enhanced reliability characteristics: higher voltage rating (16 V vs. 10 V), extended operating temperature range (-55°C ~ 105°C vs. -40°C ~ 85°C), and superior ripple current capacity. The component carries AEC-Q200 automotive qualification, indicating compliance with automotive-grade reliability standards.

For applications requiring the original B41002A3156M specifications, the EEA-FC1C150 provides equivalent or superior performance across all critical parameters while maintaining active product status and current manufacturing availability.

Frequently Asked Questions (FAQ)

Q: Can the EEA-FC1C150 be used as a direct replacement for B41002A3156M?

A: Yes. Both components share identical capacitance (15 µF), tolerance (±20%), physical dimensions (0.157" diameter × 0.315" height), lead spacing (0.059"), and package type (Radial, Can, Through Hole). The EEA-FC1C150 has a higher voltage rating (16 V) and extended temperature range, making it suitable for the original application.

Q: What are the key differences between these components?

A: The primary differences are voltage rating (10 V vs. 16 V), operating temperature range (-40°C ~ 85°C vs. -55°C ~ 105°C), lifetime rating (1000 Hrs @ 85°C vs. 1000 Hrs @ 105°C), and ripple current capacity. The EEA-FC1C150 provides enhanced performance in all these areas.

Q: Are there any PCB layout considerations when substituting?

A: No. Both components have identical lead spacing (0.059" / 1.50 mm) and physical dimensions, allowing direct PCB substitution without layout modifications.

Q: What is the product status difference?

A: The B41002A3156M is obsolete, while the EEA-FC1C150 is active and currently in production. This ensures long-term availability and supply chain continuity for the substitute component.

Q: Are both components RoHS compliant?

A: Yes. Both the B41002A3156M and EEA-FC1C150 are ROHS3 compliant.
