Substitute Part Grouping Explanation

Substitution eligibility for the 416F384X2IST is determined by strict equivalence across the following critical parameters:

• Frequency: 38.4 MHz (exact match required)
• Frequency Tolerance: ±15ppm (exact match required)
• ESR: 60 Ohms (exact match required)
• Operating Mode: Fundamental (exact match required)
• Package / Case: 4-SMD, No Lead (exact match required)
• Physical Dimensions: 0.063" L x 0.047" W, 0.018" max height (exact match required)
• Operating Temperature Range: -40°C to 85°C (exact match required)
• RoHS Compliance: ROHS3 Compliant (exact match required)

The 416F384X2ISR meets all substitution criteria as a parametric equivalent within the CTS-Frequency Controls 416 series.

Parameter Comparison
