Substitute Part Grouping Explanation

Substitute parts for the 416F360X2CDT are determined by strict equivalence across all critical electrical and mechanical parameters. The substitution criteria are:

Frequency: 36 MHz (exact match required)
Frequency Tolerance: ±15ppm (exact match required)
Load Capacitance: 18pF (exact match required)
ESR: 80 Ohms (exact match required)
Operating Mode: Fundamental (exact match required)
Operating Temperature Range: -20°C to 70°C (exact match required)
Package / Case: 4-SMD, No Lead (exact match required)
Physical Dimensions: 0.063" L x 0.047" W, 0.018" max height (exact match required)
RoHS and MSL Compliance: ROHS3 Compliant, MSL 1 (exact match required)

The primary difference between the main part and substitutes is packaging configuration (cut tape vs. tape & reel) and product status (discontinued vs. active).

Engineering Selection Recommendations

Both 416F360X2CDR and 416F360XXCDR are direct parametric equivalents to the 416F360X2CDT. Selection between these substitutes should be based on the following factors:

416F360X2CDR: This part maintains identical electrical specifications to the main part and carries Active product status. It is packaged in Tape & Reel format with higher inventory availability (1157 pcs), making it suitable for production environments requiring bulk component quantities.

416F360XXCDR: This part also maintains identical electrical specifications and Active product status. It features improved frequency stability at ±15ppm (compared to ±20ppm in the main part and 416F360X2CDR), while maintaining the same ±15ppm frequency tolerance. Tape & Reel packaging is standard for this variant.

Both substitutes meet ROHS3 compliance and MSL 1 requirements, ensuring compatibility with modern manufacturing and environmental standards. The choice between them depends on packaging requirements and inventory availability for your specific application volume.

Frequently Asked Questions (FAQ)

Q: Can 416F360X2CDR be used as a direct replacement for 416F360X2CDT?

A: Yes. Both parts share identical electrical parameters (36 MHz frequency, ±15ppm tolerance, 18pF load capacitance, 80 Ohms ESR) and mechanical specifications (4-SMD No Lead package, 1.60mm x 1.20mm dimensions). The primary difference is packaging format: 416F360X2CDT uses cut tape, while 416F360X2CDR uses Tape & Reel. Both are functionally equivalent in circuit applications.

Q: What is the difference between 416F360X2CDR and 416F360XXCDR?

A: Both parts are electrically and mechanically equivalent with identical frequency (36 MHz), load capacitance (18pF), and ESR (80 Ohms). The distinction is in frequency stability specification: 416F360XXCDR offers ±15ppm stability compared to ±20ppm for 416F360X2CDR. Both maintain ±15ppm frequency tolerance and are packaged in Tape & Reel format.

Q: Why is the main part 416F360X2CDT discontinued?

A: The 416F360X2CDT is discontinued at DiGi Electronics. Active equivalent parts 416F360X2CDR and 416F360XXCDR remain available for new designs and production applications.

Q: Are there packaging compatibility concerns when switching from 416F360X2CDT to the substitute parts?

A: No. All three parts use identical 4-SMD No Lead packaging with matching physical dimensions (0.063" L x 0.047" W, 0.018" max height). The substitutes are supplied in Tape & Reel format rather than cut tape, which is standard for production environments and does not affect circuit-level compatibility.

Q: Do the substitute parts meet the same compliance standards?

A: Yes. Both 416F360X2CDR and 416F360XXCDR are ROHS3 Compliant with MSL 1 (Unlimited) rating, matching the compliance profile of the main part.
