Substitute Part Grouping Explanation

Substitution of the AX5PAF2-1800.0000C is determined by the following critical parameters:

• Frequency: 1.8 GHz (exact match required)
• Output Type: LVPECL (exact match required)
• Package Type: 8-SMD, No Lead (exact match required)
• Package Dimensions: 5.00mm x 3.20mm footprint (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Frequency Stability: ±20ppm (exact match required)
• Function: Enable/Disable (exact match required)
• Series: ClearClock™ AX5 (exact match required)

The substitute part AX5PBF1-1800.0000C meets all mechanical and electrical compatibility requirements. The primary difference is the supply voltage specification: the substitute operates at 2.5V instead of 3.3V. This voltage difference requires circuit-level evaluation to determine compatibility with the target application.

Parameter Comparison

Engineering Selection Recommendations

Both the AX5PAF2-1800.0000C and AX5PBF1-1800.0000C are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. Both parts carry an MSL rating of 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling.

The AX5PBF1-1800.0000C substitute is mechanically and electrically compatible with the original part across all parameters except supply voltage. Selection between these parts depends on the power supply architecture of the target application. If the circuit design operates at 2.5V, the substitute provides direct compatibility. If the circuit requires 3.3V operation, alternative sourcing or circuit redesign may be necessary.

Frequently Asked Questions (FAQ)

Q: Can the AX5PBF1-1800.0000C replace the AX5PAF2-1800.0000C in all applications?

A: The substitute is mechanically and electrically compatible in all parameters except supply voltage. Compatibility depends on whether your circuit operates at 2.5V or 3.3V. If your design uses 3.3V power rails, the substitute cannot be used without circuit modification.

Q: Are the package dimensions identical between these parts?

A: Yes. Both parts use the same 8-SMD, No Lead package with identical footprint dimensions (5.00mm x 3.20mm) and maximum seated height (1.50mm). PCB layout and reflow profiles remain unchanged.

Q: Do both parts meet the same environmental and compliance standards?

A: Yes. Both the AX5PAF2-1800.0000C and AX5PBF1-1800.0000C are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) ratings. Handling and storage requirements are identical.

Q: What is the frequency stability specification for both parts?

A: Both parts maintain ±20ppm frequency stability across the -40°C to 85°C operating temperature range.

Q: Are there any other substitute parts available for the AX5PAF2-1800.0000C?

A: Based on the provided data, AX5PBF1-1800.0000C is the documented substitute. Other 1.8 GHz LVPECL oscillators in the ClearClock™ AX5 series may exist, but only parts meeting all specified parameters are considered equivalent substitutes.
