Key Parameters

Substitute Part Grouping Explanation

Substitution of the ST2001FX is determined by electrical and mechanical compatibility within the following criteria:

Electrical Parameters:

• Transistor type must be NPN
• Voltage rating must equal or exceed 600 V collector-emitter breakdown voltage
• Current rating must equal or exceed 10 A maximum collector current
• Power dissipation must equal or exceed 63 W
• Operating temperature must support 150°C junction temperature

Mechanical Parameters:

• Package type must be ISOWATT-218FX
• Mounting configuration must be through-hole

The ST1510FX meets these substitution criteria with enhanced electrical specifications while maintaining identical mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The ST1510FX is a direct substitute for the obsolete ST2001FX. The substitute part maintains identical mechanical compatibility through the ISOWATT-218FX package and through-hole mounting configuration, ensuring direct board-level replacement without layout modifications.

The ST1510FX provides enhanced electrical performance with 750 V collector-emitter breakdown voltage (compared to 600 V) and 12 A maximum collector current (compared to 10 A), offering improved design margin for voltage and current stress conditions. Both parts maintain identical 150°C maximum junction temperature ratings and equivalent power dissipation specifications.

Both the ST2001FX and ST1510FX are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity classification. The ST1510FX holds active product status with current manufacturing availability, whereas the ST2001FX is obsolete. Compliance certifications and regulatory classifications are equivalent between both parts.

Frequently Asked Questions (FAQ)

Q: Can the ST1510FX directly replace the ST2001FX in existing designs?

A: Yes. The ST1510FX is mechanically and electrically compatible for direct substitution. Both parts use the ISOWATT-218FX package with through-hole mounting, requiring no PCB layout changes. The ST1510FX provides equal or superior electrical performance across all rated parameters.

Q: What are the key differences between ST2001FX and ST1510FX?

A: The ST1510FX provides higher voltage rating (750 V versus 600 V) and higher current rating (12 A versus 10 A).
