Key Parameters

Substitute Part Grouping Explanation

Substitution of the 416F30033CST is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain:

• Identical frequency specification: 30 MHz
• Matching frequency stability and tolerance: ±30ppm
• Equivalent series resistance: 80 Ohms
• Same operating mode: Fundamental
• Identical load capacitance classification: Series
• Matching temperature operating range: -20°C to 70°C
• Identical physical package: 4-SMD, No Lead
• Matching dimensional specifications: 0.063" L x 0.047" W (1.60mm x 1.20mm)
• Same height specification: 0.018" (0.45mm) maximum seated height
• Equivalent compliance certifications: ROHS3, MSL 1

The 416F30033CSR meets all these criteria and is classified as a parametric equivalent from the same manufacturer series.

Parameter Comparison

Engineering Selection Recommendations

The 416F30033CSR is a direct parametric equivalent to the 416F30033CST. Both parts are manufactured by CTS-Frequency Controls within the 416 series and share identical electrical specifications and physical dimensions. The primary distinction is product status: the 416F30033CST is discontinued, while the 416F30033CSR remains active in production.

Both parts maintain ROHS3 compliance and MSL 1 rating, ensuring equivalent environmental and handling characteristics. The 416F30033CSR is available in Tape & Reel packaging, which is standard for production environments, whereas the main part was supplied in bulk packaging.

For applications currently using the 416F30033CST, direct substitution with the 416F30033CSR is supported without circuit modification or re-qualification, provided the Tape & Reel packaging format is compatible with assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the 416F30033CSR be used as a direct replacement for the 416F30033CST?

A: Yes. Both parts are parametric equivalents with identical frequency, stability, ESR, operating temperature range, and physical dimensions. No circuit changes are required.

Q: What is the difference between these two parts?

A: The 416F30033CSR is the active production equivalent of the discontinued 416F30033CST. The primary difference is packaging format: the CST was supplied in bulk, while the CSR is supplied in Tape & Reel (TR) format.

Q: Are there any compliance differences between the two parts?

A: No. Both parts are ROHS3 compliant with MSL 1 rating and identical REACH and ECCN classifications.

Q: Does the Tape & Reel packaging affect circuit performance?

A: No. Tape & Reel packaging is a supply format only and does not affect electrical performance or physical specifications of the crystal component itself.

Q: What are the critical parameters for substituting a 30 MHz crystal in this series?

A: Frequency (30 MHz), frequency stability (±30ppm), ESR (80 Ohms), operating mode (Fundamental), load capacitance (Series), operating temperature range (-20°C to 70°C), and physical package dimensions (4-SMD, No Lead, 1.60mm x 1.20mm x 0.45mm max height) must all match exactly.
