Substitute Part Grouping Explanation

Substitution eligibility for 30 MHz crystal oscillators is determined by strict equivalence across electrical and mechanical parameters. The following criteria must be met for valid substitution:

Critical Electrical Parameters (Must Match Exactly):

• Frequency: 30 MHz
• Frequency Stability: ±10ppm
• Load Capacitance: 18pF
• ESR: 80 Ohms
• Operating Mode: Fundamental

Critical Mechanical Parameters (Must Match Exactly):

• Package / Case: 4-SMD, No Lead
• Mounting Type: Surface Mount
• Operating Temperature Range: -20°C to 70°C

Allowable Variations:

• Physical dimensions (length, width, height) may vary within the 4-SMD, No Lead package specification
• Packaging format (bulk vs. Tape & Reel)
• Product status (active vs. discontinued)
• Inventory availability

The substitute parts listed below meet all critical electrical and mechanical requirements and are therefore direct equivalents for the 402F30011CDT.

Parameter Comparison

Engineering Selection Recommendations

402F30011CDR (Parametric Equivalent): This part is the primary substitute for the discontinued 402F30011CDT. It maintains identical electrical specifications, physical dimensions, and height characteristics. The part is currently active with 638 units in stock. The only difference is packaging format (Tape & Reel vs. bulk), which does not affect electrical performance or PCB compatibility. This part is recommended for direct replacement in production environments.

416F30011CDR (Similar Substitute): This part provides an alternative with identical electrical specifications and active product status (1129 units in stock). The 416 series designation indicates a different design series from CTS-Frequency Controls. Physical dimensions are smaller (1.60mm x 1.20mm vs. 2.00mm x 1.60mm) and seated height is reduced (0.45mm vs. 0.55mm). This part is suitable for applications where PCB space constraints favor compact packaging. All electrical parameters remain equivalent.

Both substitute parts are ROHS3 compliant, REACH unaffected, and maintain MSL 1 rating identical to the main part. Selection between 402F30011CDR and 416F30011CDR depends on PCB layout requirements and packaging preferences.

Frequently Asked Questions (FAQ)

Q: Can 402F30011CDR be used as a direct replacement for 402F30011CDT?

A: Yes. The 402F30011CDR is a parametric equivalent with identical electrical specifications (30 MHz, ±10ppm stability, 18pF load capacitance, 80 Ohms ESR) and mechanical compatibility (4-SMD, No Lead package, surface mount). The only difference is packaging format (Tape & Reel vs. bulk), which does not affect circuit performance or PCB assembly.

Q: What is the difference between 402F30011CDR and 416F30011CDR?

A: Both parts are electrically identical 30 MHz crystals with ±10ppm stability and 18pF load capacitance. The primary differences are: (1) Series designation (402 vs. 416), (2) Physical dimensions (402F: 2.00mm x 1.60mm; 416F: 1.60mm x 1.20mm), and (3) Seated height (402F: 0.55mm; 416F: 0.45mm). The 416F is more compact and suitable for space-constrained applications.

Q: Are there any compliance or certification differences between these parts?

A: No. All three parts (402F30011CDT, 402F30011CDR, and 416F30011CDR) are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. Compliance status is identical across all variants.

Q: Which substitute should I select for new production?

A: For new production, 402F30011CDR is recommended as the primary choice due to identical physical dimensions and active product status. If PCB layout requires compact packaging, 416F30011CDR is an acceptable alternative with the same electrical performance.

Q: Can these parts be used interchangeably in the same circuit design?

A: Yes, provided PCB layout accommodates the physical dimensions of the selected part. The 402F30011CDR maintains identical footprint to the original 402F30011CDT. The 416F30011CDR has a smaller footprint and may require PCB layout verification to confirm clearance compatibility.
