Substitute Part Grouping Explanation

Substitute parts for the 416F25035ATT are determined by matching the following critical parameters:

Frequency: 25 MHz (exact match required)
Frequency Tolerance: ±30 ppm (exact match required)
Load Capacitance: 6 pF (exact match required)
ESR: 120 Ohms (exact match required)
Operating Mode: Fundamental (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)
Operating Temperature Range: -10°C to 60°C (exact match required)
RoHS and MSL Compliance: ROHS3 Compliant, MSL 1 (exact match required)

The 416F25035ATR and 416F25033ATR meet all substitution criteria. Both parts are manufactured by CTS-Frequency Controls within the same 416 series and maintain identical electrical and mechanical specifications as the main part.

Engineering Selection Recommendations

Both 416F25035ATR and 416F25033ATR are suitable replacements for the discontinued 416F25035ATT. Selection between the two substitute parts should be based on product availability and procurement requirements:

The 416F25035ATR maintains identical specifications to the main part, including frequency stability of ±50 ppm, and is currently in active production with 1099 pieces in stock.

The 416F25033ATR offers improved frequency stability at ±30 ppm while maintaining all other electrical and mechanical parameters. This part is also in active production with 917 pieces in stock.

Both substitute parts are ROHS3 compliant, carry MSL 1 rating, and are available in Tape & Reel packaging suitable for automated assembly processes. The choice between these substitutes depends on application-specific stability requirements and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can 416F25035ATR and 416F25033ATR be used interchangeably with 416F25035ATT?

A: Yes. Both substitute parts match all critical electrical and mechanical parameters of the main part, including frequency, load capacitance, ESR, package type, and physical dimensions. The primary difference is product status (active vs. discontinued) and packaging format (Tape & Reel vs. unspecified).

Q: What is the difference between 416F25035ATR and 416F25033ATR?

A: The primary difference is frequency stability. The 416F25035ATR has ±50 ppm stability, matching the main part. The 416F25033ATR has ±30 ppm stability, offering tighter tolerance. Both maintain ±30 ppm frequency tolerance and all other specifications.

Q: Are these parts suitable for surface mount assembly?

A: Yes. All three parts use 4-SMD, No Lead surface mount packaging with identical dimensions (0.063" L x 0.047" W, 0.018" max height), making them compatible with standard SMD assembly equipment and processes.

Q: What is the significance of MSL 1 rating?

A: MSL 1 indicates unlimited shelf life with no moisture sensitivity restrictions. These parts do not require special moisture control during storage or handling.

Q: Are substitute parts RoHS compliant?

A: Yes. Both 416F25035ATR and 416F25033ATR are ROHS3 compliant, meeting environmental and regulatory requirements equivalent to the main part.
