CTS-Frequency Controls 416F25035ADT 25 MHz Crystal Equivalent & Substitute Parts

Part Overview

The CTS-Frequency Controls 416F25035ADT is a 25 MHz fundamental mode crystal oscillator in a 4-SMD, No Lead surface mount package. This part is discontinued at DiGi Electronics but remains available through inventory channels with 814 pieces in stock. The 25 MHz frequency with ±30ppm tolerance and 18pF load capacitance makes it suitable for timing and clock generation applications requiring precise frequency control. Due to its discontinued status, equivalent substitute parts from the same manufacturer series are available to ensure design continuity and supply chain reliability.

Substitute Part Grouping Explanation

Substitution eligibility for the 416F25035ADT is determined by the following critical parameters that must remain constant across all equivalent parts:

• Frequency: 25 MHz (exact match required)
• Frequency Tolerance: ±30ppm (exact match required)
• Load Capacitance: 18pF (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 two substitute parts listed below meet all these critical parameters and are sourced from the same CTS-Frequency Controls 416 series. Differences in packaging format (Tape & Reel vs. bulk) and product status (Active vs. Discontinued) do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts 416F25033ADR and 416F25035ADR are direct electrical and mechanical equivalents to the 416F25035ADT. Selection between these options should be based on the following factors:

416F25033ADR: This part carries an Active product status with improved frequency stability specification of ±30ppm, matching the main part's tolerance requirement. It is available in Tape & Reel packaging with 827 pieces in current inventory.

416F25035ADR: This part also carries an Active product status and is available in Tape & Reel packaging with 882 pieces in current inventory. Frequency stability is specified at ±50ppm, which exceeds the ±30ppm tolerance requirement but remains within acceptable operating parameters for the 25 MHz fundamental mode application.

Both substitute parts maintain full ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard manufacturing and storage protocols. The choice between substitutes depends on procurement volume requirements, packaging preferences, and inventory availability at the time of component selection.

Frequently Asked Questions (FAQ)

Q: Can 416F25033ADR and 416F25035ADR be used interchangeably with 416F25035ADT?

A: Yes. Both substitute parts meet all critical electrical and mechanical parameters: 25 MHz frequency, ±30ppm tolerance, 18pF load capacitance, 120 Ohms ESR, 4-SMD No Lead package, and identical physical dimensions. The only differences are product status (Active vs. Discontinued) and packaging format (Tape & Reel vs. bulk), neither of which affects circuit performance or PCB assembly compatibility.

Q: What is the significance of the frequency stability specification difference between the substitutes?

A: The 416F25033ADR specifies ±30ppm frequency stability, while the 416F25035ADR specifies ±50ppm. Both parts meet the ±30ppm frequency tolerance requirement. Frequency stability refers to long-term drift characteristics, while frequency tolerance defines the initial accuracy at room temperature. Both specifications are within acceptable parameters for 25 MHz timing applications.

Q: Are there any packaging or handling differences between the main part and substitutes?

A: The main part 416F25035ADT is supplied in bulk packaging, while both substitutes (416F25033ADR and 416F25035ADR) are supplied in Tape & Reel format. Both packaging formats contain identical components with the same electrical and mechanical specifications. Tape & Reel packaging is standard for automated assembly processes. All parts share MSL 1 (Unlimited) moisture sensitivity rating, requiring no special storage precautions.

Q: Do the substitute parts maintain the same RoHS and regulatory compliance?

A: Yes. All three parts are ROHS3 Compliant, REACH Unaffected, and carry the same ECCN (EAR99) and HTSUS (8541.60.0060) classifications. Regulatory and environmental compliance is identical across the main part and both substitutes.

Q: Which substitute part should be selected for new designs?

A: For new designs, either 416F25033ADR or 416F25035ADR is appropriate. The 416F25033ADR offers tighter frequency stability (±30ppm), while the 416F25035ADR provides higher inventory availability (882 pieces). Both are Active products with established supply chains. Selection should be based on procurement lead times, volume requirements, and packaging preferences for your manufacturing process.
