Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the NBC12430FAG is determined by the following critical parameters:

• Package / Case: 32-LQFP (7x7) — mechanical and electrical interface compatibility
• Input Type: Crystal — signal source compatibility
• Output Type: PECL — output signal standard compatibility
• Number of Circuits: 1 — functional equivalence
• Ratio - Input:Output: 1:1 — frequency relationship
• Differential - Input:Output: No/Yes — signal characteristics
• Voltage - Supply: 3.135V ~ 5.25V — power supply compatibility
• Operating Temperature: 0°C ~ 70°C — thermal operating range
• Mounting Type: Surface Mount — assembly process compatibility

The NBC12429FAG qualifies as a parametric equivalent substitute. Both devices share identical mechanical packaging, electrical interfaces, supply voltage ranges, operating temperature specifications, and functional architecture. The primary distinction is maximum frequency specification: NBC12430FAG operates to 800MHz, while NBC12429FAG operates to 400MHz.

Parameter Comparison

Engineering Selection Recommendations
