Key Parameters

Substitute Part Grouping Explanation

No substitute parts are currently available in the provided database. Substitution of the AX7PAF3-300.0000C requires identification of alternative oscillators that meet the following critical parameters:

• Frequency: 300 MHz (exact match required)
• Output Standard: LVPECL (low-voltage positive emitter-coupled logic)
• Supply Voltage: 3.3V
• Enable/Disable Control: Required
• Package Type: 8-SMD, No Lead surface mount
• Package Dimensions: 7.00mm x 5.00mm footprint
• Frequency Stability: ±25ppm or better
• Operating Temperature: -40°C to 85°C minimum range
• RoHS3 Compliance: Required for regulatory alignment

Alternative sources must maintain compatibility across all listed parameters to ensure direct replacement without circuit redesign.

Engineering Selection Recommendations

Given the discontinued status of the AX7PAF3-300.0000C, component selection should prioritize:

• RoHS3 compliance to maintain regulatory alignment with the original part
• MSL 1 moisture sensitivity rating or equivalent to preserve handling and storage compatibility
• Exact frequency and output standard matching to eliminate circuit redesign requirements
• Identical or superior frequency stability specifications
• Surface mount 8-SMD, No Lead package compatibility with existing PCB layouts

Procurement should verify current availability and lead times for any identified alternatives before design commitment.

Frequently Asked Questions (FAQ)

Q: Can I use a different frequency oscillator as a substitute? A: No. The 300 MHz frequency is application-specific. Substitutes must match this frequency exactly to maintain system performance and timing requirements.

Q: What does LVPECL output mean for substitution purposes? A: LVPECL (Low-Voltage Positive Emitter-Coupled Logic) is a specific signaling standard. Only oscillators with LVPECL output can replace this component without signal conditioning circuitry modifications.

Q: Is the 8-SMD, No Lead package critical for substitution? A: Yes. The package type and footprint dimensions (7.00mm x 5.00mm) must match to ensure compatibility with existing PCB layouts and assembly processes.

Q: Does the enable/disable function need to be present in a substitute? A: Yes. The enable/disable control function is a required feature. Substitutes must provide equivalent control capability.

Q: What is the significance of ±25ppm frequency stability? A: Frequency stability defines the oscillator's accuracy over temperature and time. Substitutes should meet or exceed this specification to maintain system timing integrity.

Q: Why is RoHS3 compliance important for substitution? A: RoHS3 compliance ensures the substitute meets current environmental and regulatory standards. This is essential for product certification and market compliance.

Q: Can I substitute with a different supply voltage oscillator? A: No. The 3.3V supply voltage is fixed by the system design. Only 3.3V oscillators are compatible without additional power supply modifications.
