Substitute Part Grouping Explanation

Substitution of the XC9252C08AVR-G is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part XC9252A08AVR-G qualifies as a parametric equivalent based on the following criteria:

Electrical Parameter Equivalence:

• Identical voltage supply range (3V ~ 30V)
• Identical switching frequency range (280kHz ~ 550kHz)
• Identical maximum duty cycle (100%)
• Identical control feature set (Current Limit, Enable, Frequency Control, Power Good, Soft Start)
• Identical operating temperature range (-40°C ~ 105°C)
• Identical output configuration (Positive, single output, single phase)
• Identical topology (Buck regulator controller)

Mechanical Parameter Equivalence:

• Identical package type (16-LSSOP, 0.173", 4.40mm Width)
• Identical supplier device package (16-TSSOP)
• Identical mounting type (Surface Mount)

Compliance Equivalence:

• Identical RoHS3 compliance status
• Identical REACH status (REACH Unaffected)
• Identical Moisture Sensitivity Level (MSL 1 - Unlimited)

Both parts share the same base product number (XC9252) and are manufactured by the same supplier (Torex Semiconductor Ltd). The substitution is valid for any application requiring buck regulator controller functionality within the specified electrical and thermal operating ranges.
