Substitute Part Grouping Explanation

Substitution for the 416F25035CLT is determined by the following critical parameters:

• Frequency: Must be 25 MHz
• Frequency Tolerance: Must be ±30ppm
• Load Capacitance: 12pF (primary specification) or 10pF (acceptable with circuit design consideration)
• ESR: Must be 120 Ohms
• Operating Mode: Fundamental
• Package / Case: 4-SMD, No Lead
• Physical Dimensions: 1.60mm × 1.20mm
• Operating Temperature Range: -20°C to 70°C minimum
• RoHS & Compliance: ROHS3 Compliant, REACH Unaffected

The substitute parts listed below maintain these critical electrical and mechanical parameters, ensuring functional compatibility in applications originally designed for the 416F25035CLT.

Parameter Comparison

Engineering Selection Recommendations

416F25033CLR is the primary parametric equivalent. It maintains identical frequency, tolerance, load capacitance, and ESR specifications while offering improved frequency stability (±30ppm vs. ±50ppm). This part is currently active and available in Tape & Reel packaging, making it suitable for production environments requiring higher stability margins.

416F25035CLR is a direct functional equivalent with matching electrical specifications to the original 416F25035CLT. Both parts share ±50ppm frequency stability and 12pF load capacitance. This part is active and available in Tape & Reel packaging.

416F25035CAR is functionally compatible with a load capacitance specification of 10pF instead of 12pF. This part maintains all other critical parameters including frequency, tolerance, ESR, and operating temperature range. Selection of this part requires circuit design verification to confirm compatibility with the 10pF load capacitance specification.

All substitute parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can I use 416F25035CAR as a direct replacement for 416F25035CLT?

A: The 416F25035CAR is electrically and mechanically compatible with the exception of load capacitance. The original part specifies 12pF load capacitance, while the CAR variant specifies 10pF. Direct substitution requires circuit design verification to confirm the oscillator circuit is compatible with 10pF load capacitance. Frequency accuracy and stability may be affected if the circuit was optimized for 12pF.

Q: What is the difference between 416F25033CLR and 416F25035CLR?

A: Both parts are parametric equivalents with identical frequency (25 MHz), tolerance (±30ppm), load capacitance (12pF), and ESR (120 Ohms). The primary difference is frequency stability: 416F25033CLR offers ±30ppm stability while 416F25035CLR offers ±50ppm stability. For applications requiring tighter frequency stability over temperature, 416F25033CLR is the preferred selection.

Q: Are all substitute parts available in the same packaging as the original 416F25035CLT?

A: The original 416F25035CLT was supplied in bulk packaging and is discontinued. All active substitute parts (416F25033CLR, 416F25035CLR, 416F25035CAR) are supplied in Tape & Reel (TR) packaging, which is standard for production environments. The physical package and form factor (4-SMD, No Lead, 1.60mm × 1.20mm) remain identical across all parts.

Q: Do all substitute parts meet the same compliance requirements?

A: Yes. All substitute parts are ROHS3 compliant and REACH unaffected, matching the compliance status of the original 416F25035CLT. All parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements.

Q: Which substitute part should I select for a new design?

A: For new designs, select based on your frequency stability requirements. If ±30ppm stability is acceptable, 416F25033CLR is recommended. If ±50ppm stability is required, select either 416F25035CLR or 416F25035CAR depending on your circuit's load capacitance specification (12pF or 10pF respectively). All parts are active and available from inventory.
