416F50035ITT 50 MHz Crystal Equivalent & Substitute Parts

Part Overview

The 416F50035ITT is a 50 MHz fundamental mode crystal oscillator manufactured by CTS-Frequency Controls, designed for surface mount applications in a compact 4-SMD, No Lead package. This part is discontinued at DiGi Electronics, making equivalent substitute parts necessary for ongoing production and maintenance applications. The crystal operates across the industrial temperature range of -40°C to 85°C with a load capacitance of 6pF and 60 Ohms equivalent series resistance.

Substitute Part Grouping Explanation

Substitution for the 416F50035ITT is determined by strict equivalence across the following critical parameters:

Frequency: 50 MHz (exact match required)
Frequency Tolerance: ±30ppm (exact match required)
Load Capacitance: 6pF (exact match required)
ESR: 60 Ohms (exact match required)
Package Type: 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: -40°C to 85°C (exact match required)

The substitute parts listed below meet all these criteria and are therefore electrically and mechanically interchangeable with the 416F50035ITT in applications requiring these specifications.

Engineering Selection Recommendations

Both 416F50035ITR and 416F50033ITR are active products from CTS-Frequency Controls and meet all electrical and mechanical specifications of the discontinued 416F50035ITT. Selection between these substitutes should be based on the following factors:

The 416F50035ITR maintains identical frequency stability (±50ppm) to the original part and is available in Tape & Reel packaging, suitable for high-volume production environments. The 416F50033ITR offers improved frequency stability at ±30ppm and is also available in Tape & Reel packaging, providing enhanced performance for applications requiring tighter frequency tolerance control.

Both substitutes are ROHS3 compliant, carry MSL 1 rating, and are REACH unaffected, meeting current regulatory requirements for electronic component procurement.

Frequently Asked Questions (FAQ)

Q: Can 416F50035ITR and 416F50033ITR be used interchangeably with 416F50035ITT?

A: Yes. Both parts meet all critical electrical and mechanical parameters: 50 MHz frequency, ±30ppm frequency tolerance, 6pF load capacitance, 60 Ohms ESR, identical package dimensions, and operating temperature range. The primary difference is product status (active vs. discontinued) and packaging format (Tape & Reel vs. bulk).

Q: What is the difference between 416F50035ITR and 416F50033ITR?

A: The primary difference is frequency stability specification. The 416F50035ITR has ±50ppm frequency stability, while the 416F50033ITR has ±30ppm frequency stability. Both meet the ±30ppm frequency tolerance requirement. All other electrical and mechanical parameters are identical.

Q: Are there packaging differences between the original part and substitutes?

A: The 416F50035ITT is supplied in bulk packaging, while both 416F50035ITR and 416F50033ITR are supplied in Tape & Reel (TR) format. This affects handling and assembly processes but does not impact component performance or compatibility.

Q: Do the substitute parts meet current compliance standards?

A: Yes. Both 416F50035ITR and 416F50033ITR are ROHS3 compliant, carry MSL 1 (Unlimited) moisture sensitivity rating, and are REACH unaffected, meeting current regulatory requirements for electronic component procurement and use.

Q: What is the load capacitance specification, and why is it important for substitution?

A: Load capacitance is specified at 6pF for all three parts. This parameter determines the crystal's operating frequency and must match exactly for direct substitution. Mismatched load capacitance will result in frequency deviation outside tolerance specifications.
