Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 524SCMGI8 are identified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters that must match identically:

• Clock Distribution Topology: 1:4 input-to-output ratio
• Maximum Operating Frequency: 200 MHz
• Logic Levels: LVCMOS input and output
• Supply Voltage Ranges: 1.71V ~ 1.89V, 2.375V ~ 2.625V, 3.135V ~ 3.465V
• Operating Temperature Range: -40°C ~ 105°C
• Package Type: 8-UFDFN (8-VFQFN 2x2)
• Mounting Technology: Surface Mount
• Regulatory Compliance: ROHS3 Compliant, REACH Unaffected

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes. The 5PB1104CMGK/W satisfies all specified parameters and is therefore a valid substitute for the 524SCMGI8.

Parameter Comparison

Engineering Selection Recommendations

The 5PB1104CMGK/W is a direct parametric equivalent to the 524SCMGI8 and is suitable for substitution in applications requiring identical electrical performance and mechanical compatibility. Both parts are manufactured by Renesas Electronics Corporation and maintain active production status, ensuring long-term availability and supply chain stability.
