Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FAN7602N are identified based on strict electrical and mechanical parameter matching. The following criteria determine substitutability:

• Topology: Flyback converter architecture
• Output Isolation: Isolated configuration
• Supply Voltage Range: 8V ~ 20V
• Switching Frequency: 65kHz
• Power Rating: 48W
• Fault Protection: Over Load and Over Voltage protection
• Operating Temperature Range: -25°C ~ 125°C
• Package: 8-DIP through-hole form factor
• Pin Configuration: Identical base product number (FAN7602)

Parts meeting all these parameters are classified as direct parametric equivalents and may be used as substitutes without circuit redesign.

Parameter Comparison

Engineering Selection Recommendations

The FAN7602BN manufactured by Fairchild Semiconductor is a direct parametric equivalent to the FAN7602N. All critical electrical parameters, switching characteristics, and package specifications are identical. The FAN7602BN maintains active product status, ensuring continued availability and supply chain reliability.

The FAN7602BN carries ROHS3 compliance certification, meeting current environmental and regulatory requirements. The higher moisture sensitivity level (MSL 3) requires adherence to standard moisture control procedures during storage and handling, consistent with industry practices for 8-DIP through-hole components.

Direct pin-for-pin substitution is supported without circuit modification. Both devices share the same base product number (FAN7602) and are designed for identical application topologies.

Frequently Asked Questions (FAQ)

Q: Can FAN7602BN be used as a direct replacement for FAN7602N?
