Substitute Part Grouping Explanation

The NBC12429FAR2G qualifies as a direct substitute based on identical electrical and mechanical parameters. Substitution criteria are determined by the following parameters, all of which match between the main part and substitute:

• Frequency maximum: 400MHz
• Input configuration: Crystal
• Output configuration: PECL
• Supply voltage range: 3.135V ~ 5.25V
• Operating temperature range: 0°C ~ 70°C
• Package type: 32-LQFP (7x7)
• Number of circuits: 1
• Input:Output ratio: 1:1
• Differential input/output: No/Yes

The primary distinction between these parts is product status and compliance certification, not functional capability.

Parameter Comparison
