Engineering Selection Recommendations

Both substitute parts (416F36022ADR and 416F36023ADR) are active products from CTS-Frequency Controls and provide direct electrical and mechanical equivalence to the discontinued 416F36023ADT. Selection between substitutes should be based on the following factors:

416F36022ADR: This part offers improved frequency stability at ±20ppm, which exceeds the tolerance specification of the main part. This substitute is suitable for applications requiring tighter frequency control.

416F36023ADR: This part maintains the same frequency stability specification (±30ppm) as the main part while providing active product status and Tape & Reel packaging. This substitute is suitable for direct replacement in existing designs.

Both substitutes are RoHS3 compliant with MSL 1 rating, ensuring compliance with environmental and moisture sensitivity requirements. The Tape & Reel packaging of both substitutes supports automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can 416F36022ADR and 416F36023ADR be used interchangeably with 416F36023ADT?

A: Both parts meet the critical electrical parameters (36 MHz frequency, ±20ppm tolerance, 18pF load capacitance, 80 Ohms ESR) and mechanical specifications (4-SMD No Lead package, identical dimensions). They are functionally equivalent for circuit applications.

Q: What is the difference between the two substitute parts?

A: The primary difference is frequency stability. 416F36022ADR specifies ±20ppm stability, while 416F36023ADR specifies ±30ppm stability. Both meet the ±20ppm tolerance requirement. Selection depends on application-specific stability requirements.

Q: Are the substitute parts available in the same packaging as the original?

A: The original 416F36023ADT is supplied in bulk packaging. Both substitutes (416F36022ADR and 416F36023ADR) are supplied in Tape & Reel (TR) packaging, which is standard for automated assembly and production environments.

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

A: Yes. Both 416F36022ADR and 416F36023ADR are RoHS3 compliant with MSL 1 (Unlimited) rating, matching the compliance profile of the original part.

Q: What is the operating temperature range for these crystals?

A: All three parts operate across the same temperature range: -10°C to 60°C.

Q: Are there any physical dimension differences between the main part and substitutes?

A: No. All three parts share identical physical dimensions: 0.063" L x 0.047" W (1.60mm x 1.20mm) with a maximum seated height of 0.018" (0.45mm).
