416F27022AST 27 MHz Crystal Equivalent & Substitute Parts

Part Overview

The 416F27022AST is a 27 MHz fundamental mode crystal oscillator in a 4-SMD surface mount package manufactured by CTS-Frequency Controls. This component is designed for applications requiring precise frequency generation at 27 MHz with tight frequency stability of ±20ppm. The part is discontinued at DiGi Electronics, making identification of equivalent substitutes necessary for ongoing production and maintenance applications. Substitute parts must maintain identical electrical and mechanical specifications to ensure direct replacement without circuit redesign.

Substitute Part Grouping Explanation

Substitution of the 416F27022AST is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must match the following criteria:

• Frequency: 27 MHz (exact match required)
• Frequency Stability: ±20ppm (exact match required)
• ESR: 120 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 / 1.60mm x 1.20mm (exact match required)
• Height - Seated (Max): 0.018" / 0.45mm (exact match required)
• Operating Temperature Range: -10°C to 60°C (exact match required)
• RoHS and REACH Compliance Status (exact match required)

The 416F27022ASR meets all substitution criteria as a parametric equivalent from the same manufacturer and series.

Parameter Comparison

Engineering Selection Recommendations

The 416F27022ASR is a direct parametric equivalent to the 416F27022AST. Both parts are manufactured by CTS-Frequency Controls within the same 416 series and share identical electrical and mechanical specifications.
