Key Parameters

Substitute Part Grouping Explanation

The FT8260-RT qualifies as a parametric equivalent to the FT8261-RT based on strict alignment across all critical electrical and mechanical parameters. Substitution is valid when the following criteria are met:

• Identical supply voltage range: 9.6V to 25V
• Identical package and pinout: SOT-23-6 surface mount
• Identical number of outputs: 1
• Identical internal switch configuration: Yes
• Identical operating temperature range: -40°C to 125°C
• Identical moisture sensitivity classification: MSL 3 (168 Hours)
• Identical application category: Lighting

Both parts are manufactured by Fremont Micro Devices Ltd and share the same functional topology as AC DC offline switchers with integrated switching capability. The FT8260-RT maintains full compatibility with designs originally specified for the FT8261-RT.

Parameter Comparison

Engineering Selection Recommendations

The FT8260-RT is the direct substitute for the FT8261-RT. Selection of the FT8260-RT is supported by the following factors:

• All electrical parameters match exactly, ensuring functional equivalence in lighting driver applications
• Identical package and pinout eliminate PCB redesign requirements
• Active product status of the FT8260-RT ensures long-term availability and supply chain continuity
• Both parts maintain identical compliance certifications: REACH Unaffected, EAR99 export classification, and HTSUS coding
• Moisture sensitivity classification is identical, requiring no changes to storage or handling procedures
• The FT8260-RT offers significantly higher inventory availability (5280 pcs vs. 619 pcs), reducing procurement risk

For designs currently using the FT8261-RT, direct substitution with the FT8260-RT requires no circuit modifications, PCB layout changes, or firmware updates.
