Substitute Part Grouping Explanation

Substitution for the 416F38422CLT is determined by the following critical parameters: frequency (38.4 MHz), frequency stability (±20ppm), operating mode (Fundamental), package type (4-SMD, No Lead), physical dimensions (1.60mm x 1.20mm), operating temperature range (-20°C ~ 70°C), and compliance certifications (RoHS3).

Load capacitance and ESR are secondary parameters that may vary within acceptable ranges for circuit operation. Substitute parts are grouped into two categories:

Parametric Equivalent: Parts matching all critical parameters including load capacitance and ESR specifications.

Similar Substitute: Parts matching frequency, stability, package, and dimensions but with variations in load capacitance or ESR within acceptable operating ranges.

8Q-38.400MDDQ-T (Similar Substitute): This FTS part matches frequency, stability, package, and dimensions. Load capacitance is 10pF with 80 Ohms ESR (versus 60 Ohms). Product status is Active with RoHS compliance. Circuit design must accommodate both the 10pF load capacitance and 80 Ohms ESR specifications. Highest inventory availability.

Frequently Asked Questions (FAQ)

Q: Can 416F38422CAR be used as a direct replacement for 416F38422CLT?

A: 416F38422CAR is a functional substitute with identical frequency, stability, and ESR. The load capacitance differs (10pF versus 12pF). Substitution is valid if the circuit design accommodates 10pF load capacitance. Verify oscillator circuit tuning parameters with the 10pF specification.

Q: What is the difference between 416F38422CLR and 416F38422CLT?

A: Both parts are parametrically identical in frequency, stability, load capacitance, and ESR. The primary difference is product status: 416F38422CLT is discontinued while 416F38422CLR is Active. 416F38422CLR is the recommended replacement.

Q: Can the FTS 8Q-38.400MDDQ-T replace the CTS part?

A: 8Q-38.400MDDQ-T is a functional substitute matching frequency, stability, package, and dimensions. ESR is 80 Ohms (versus 60 Ohms) and load capacitance is 10pF (versus 12pF). Circuit design must accommodate these parameter variations. Verify oscillator circuit performance with the modified ESR and load capacitance values.

Q: Are all substitute parts RoHS compliant?

A: 416F38422CLR and 416F38422CAR are ROHS3 compliant. 8Q-38.400MDDQ-T is RoHS compliant. All parts meet environmental compliance requirements for current manufacturing standards.

Q: What is the significance of load capacitance differences?

A: Load capacitance affects crystal oscillator circuit tuning and frequency accuracy. Parts with 12pF load capacitance (416F38422CLT and 416F38422CLR) require identical circuit design. Parts with 10pF load capacitance (416F38422CAR and 8Q-38.400MDDQ-T) require circuit tuning adjustment. Consult oscillator circuit design specifications before substitution.

Q: Which substitute part has the best availability?

A: 8Q-38.400MDDQ-T has the highest inventory at 6183 pieces. 416F38422CLR has 825 pieces and 416F38422CAR has 665 pieces in stock.
