Substitute Part Grouping Explanation

Substitution of the 416F38422CST is determined by strict equivalence across the following critical parameters:

• Frequency: 38.4 MHz (exact match required)
• Frequency Stability: ±20ppm (determines circuit performance tolerance)
• ESR: 60 Ohms (affects oscillator startup and drive level)
• Operating Mode: Fundamental (defines harmonic content and frequency generation method)
• Operating Temperature Range: -20°C to 70°C (establishes environmental operating limits)
• Package / Case: 4-SMD, No Lead (ensures mechanical and electrical compatibility with PCB layout)
• Physical Dimensions: 0.063" L x 0.047" W, 0.018" max height (confirms footprint compatibility)
• Compliance: ROHS3 Compliant, MSL 1 (Unlimited)

The substitute part 416F38422CSR meets all these parameters identically, establishing it as a direct parametric equivalent within the CTS-Frequency Controls 416 series.

Parameter Comparison

Engineering Selection Recommendations

The 416F38422CSR is the direct parametric equivalent to the discontinued 416F38422CST. Both parts are manufactured by CTS-Frequency Controls within the same 416 series and share identical electrical and mechanical specifications. The primary distinction is product status: the 416F38422CSR maintains active availability, while the 416F38422CST is discontinued.

For applications currently using the 416F38422CST, the 416F38422CSR provides equivalent performance without circuit redesign or re-qualification. Both parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard manufacturing and storage protocols.

The 416F38422CSR is supplied in Tape & Reel (TR) packaging, which is standard for production volume applications. If the original application used alternative packaging, verify packaging compatibility with assembly equipment before implementation.
