Key Parameters

Substitute Part Grouping Explanation

Substitution of the FAN7602CM is determined by strict equivalence across the following critical parameters:

• Topology & Isolation: Flyback converter with isolated output
• Electrical Specifications: 8V ~ 25V supply voltage, 12V startup voltage, 65kHz switching frequency, 48W power capacity, 75% duty cycle
• Fault Protection: Overload, overvoltage, and overtemperature protection
• Thermal Range: -25°C ~ 125°C operating temperature
• Package Compatibility: 8-SOIC surface mount package with 0.154" (3.90mm) width
• Pin Configuration: Identical pinout and functional equivalence

The FAN7602CMX qualifies as a direct substitute based on complete alignment with all specified electrical, thermal, and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

The FAN7602CMX is the direct substitute for the obsolete FAN7602CM. Both devices share identical electrical specifications, thermal operating range, and package configuration. The FAN7602CMX maintains active product status with current manufacturing support and improved availability (40,300 units in stock versus 1,166 units for the obsolete variant).

The FAN7602CMX carries ROHS3 compliance certification, providing additional regulatory alignment for new designs and production environments with environmental compliance requirements. Both parts maintain REACH Unaffected status and identical MSL ratings.

No design modifications, PCB layout changes, or firmware adjustments are required when transitioning from FAN7602CM to FAN7602CMX. The substitution is pin-for-pin and functionally equivalent.

Frequently Asked Questions (FAQ)

Q: Can FAN7602CMX be used as a direct replacement for FAN7602CM?

A: Yes. The FAN7602CMX is a direct substitute. All electrical parameters, thermal specifications, package dimensions, and fault protection features are identical. No circuit modifications are necessary.

Q: What is the primary difference between FAN7602CM and FAN7602CMX?

A: The FAN7602CM is obsolete with limited inventory (1,166 units). The FAN7602CMX is an active product with robust supply availability (40,300 units) and ROHS3 compliance certification.

Q: Are there any packaging differences between these parts?

A: No. Both devices use identical 8-SOIC surface mount packaging with 0.154" (3.90mm) width. Tape and reel specifications may differ, but the component itself and PCB footprint are identical.

Q: What substitution criteria determine compatibility?

A: Compatibility is based on matching topology (Flyback), isolation type (Isolated), supply voltage range (8V ~ 25V), switching frequency (65kHz), power rating (48W), fault protection features, operating temperature range (-25°C ~ 125°C), and 8-SOIC package configuration.

Q: Is RoHS compliance a factor in substitution?

A: RoHS compliance is not a substitution requirement but an additional benefit of the FAN7602CMX. Both parts are functionally equivalent. RoHS3 compliance on the FAN7602CMX supports regulatory requirements in specific markets and applications.

Q: Can other onsemi flyback converter ICs substitute for FAN7602CM?

A: No. Substitution requires exact alignment across all specified parameters. Only the FAN7602CMX meets the complete set of electrical, thermal, and mechanical requirements for direct substitution.
