Substitute Part Grouping Explanation

Substitute parts for the 416F36023AST are determined by strict equivalence across the following critical parameters:

Frequency: 36 MHz (exact match required)
Frequency Tolerance: ±20ppm (exact match required)
ESR: 80 Ohms (exact match required)
Load Capacitance: Series (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: -10°C to 60°C (exact match required)
RoHS and REACH Compliance: ROHS3 Compliant, REACH Unaffected (exact match required)

The substitute parts listed below meet all these criteria and are sourced from the same manufacturer (CTS-Frequency Controls) within the same 416 series. Differences in frequency stability (±20ppm vs ±30ppm) and product status (Active vs Discontinued) do not affect functional substitution for applications requiring the specified tolerance and performance characteristics.
