Substitute Part Grouping Explanation

Substitution of the 416F52033CST is determined by strict equivalence across the following critical parameters:

• Frequency: 52 MHz (exact match required)
• Frequency Stability: ±30ppm (exact match required)
• ESR: 60 Ohms (exact match required)
• Operating Mode: Fundamental (exact match required)
• Load Capacitance: Series (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: -20°C to 70°C (exact match required)
• RoHS Compliance: ROHS3 Compliant (exact match required)

The substitute part 416F52033CSR meets all these criteria and is therefore a direct parametric equivalent. The primary distinction between the main part and its substitute is packaging configuration and product status.
