Substitute Part Grouping Explanation

Substitution for the 416F384X2CDT is based on strict electrical and mechanical parameter matching within the CTS-Frequency Controls 416 series. The following criteria determine valid substitutes:

Frequency: 38.4 MHz (exact match required)
Frequency Tolerance: ±15ppm (exact match required)
Load Capacitance: 18pF (exact match required)
ESR: 60 Ohms (exact match required)
Operating Mode: Fundamental (exact match required)
Operating Temperature Range: -20°C ~ 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 Status: ROHS3 Compliant (exact match required)
MSL: 1 (Unlimited) (exact match required)

The primary difference between the main part and substitutes is packaging configuration (bulk vs. Tape & Reel) and product status (discontinued vs. active).

Engineering Selection Recommendations

Both 416F384X2CDR and 416F384XXCDR are direct parametric equivalents to the 416F384X2CDT. Selection between these substitutes should be based on the following factors:

416F384X2CDR: This part maintains identical electrical specifications and frequency stability (±20ppm) to the original 416F384X2CDT. It is currently active in production and available in Tape & Reel packaging, suitable for automated assembly processes. This part is the primary recommended substitute for direct replacement applications.

416F384XXCDR: This part offers improved frequency stability at ±15ppm, matching the frequency tolerance specification. It is also active in production and available in Tape & Reel packaging. This part may be selected when tighter frequency stability is required or preferred for the application.

All three parts are ROHS3 compliant, carry MSL 1 (Unlimited) moisture sensitivity rating, and are electrically and mechanically interchangeable within the specified operating parameters. The choice between active substitutes depends on packaging requirements (Tape & Reel vs. bulk) and frequency stability preferences.

Frequently Asked Questions (FAQ)

Q: Can 416F384X2CDR and 416F384XXCDR be used interchangeably with 416F384X2CDT?

A: Yes. Both substitute parts meet all electrical and mechanical specifications of the original part. They are identical in frequency (38.4 MHz), load capacitance (18pF), ESR (60 Ohms), operating temperature range (-20°C ~ 70°C), package type (4-SMD, No Lead), and physical dimensions (0.063" L x 0.047" W, 0.018" Max Height). The primary differences are product status (active vs. discontinued) and packaging format (Tape & Reel vs. bulk).

Q: What is the difference between 416F384X2CDR and 416F384XXCDR?

A: The primary difference is frequency stability. 416F384X2CDR has ±20ppm frequency stability, while 416F384XXCDR has ±15ppm frequency stability. Both maintain ±15ppm frequency tolerance. The 416F384XXCDR offers tighter stability performance. All other electrical and mechanical parameters are identical.

Q: Why is the 416F384X2CDT discontinued?

A: The 416F384X2CDT is discontinued at DiGi Electronics. The active substitute parts 416F384X2CDR and 416F384XXCDR are available from CTS-Frequency Controls and provide equivalent performance for new designs and production applications.
