Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AX7PAF2-1800.0000C are identified based on the following critical parameters that determine functional compatibility:

Mandatory Matching Parameters:

• Frequency: 1.8 GHz
• Output Type: LVPECL
• Package / Case: 8-SMD, No Lead
• Mounting Type: Surface Mount
• Operating Temperature Range: -40°C ~ 85°C
• Frequency Stability: ±25ppm

Allowable Variation Parameters:

• Voltage - Supply: 2.5V or 3.3V (both supported in ClearClock™ AX7 series)
• Current - Supply (Max): Within specified range for the series

The substitute parts listed maintain identical mechanical and electrical characteristics except for supply voltage, which is an allowable parameter variation within the ClearClock™ AX7 product family.

Parameter Comparison

Engineering Selection Recommendations

AX7PAF1-1800.0000C (Parametric Equivalent): This part is the direct parametric equivalent to the AX7PAF2-1800.0000C, maintaining identical electrical and mechanical specifications including 3.3V supply voltage. Both parts are ROHS3 compliant with MSL 1 rating. Selection of this part requires no circuit modifications and provides the closest functional match.

AX7PBF1-1800.0000C (MFR Recommended Substitute): This part differs only in supply voltage (2.5V versus 3.3V). Selection of this substitute requires circuit-level evaluation to confirm compatibility with the 2.5V supply requirement. Both parts maintain identical frequency, output type, package, and thermal specifications. ROHS3 compliance and MSL 1 rating are maintained.

All substitute parts are discontinued at DiGi Electronics, consistent with the main part status.

Frequently Asked Questions (FAQ)

Q: Can AX7PBF1-1800.0000C be used as a direct replacement for AX7PAF2-1800.0000C?

A: AX7PBF1-1800.0000C is functionally equivalent in all parameters except supply voltage. The substitute operates at 2.5V while the main part operates at 3.3V. Direct substitution is possible only if the circuit design supports 2.5V supply operation. Verify power supply capability and signal integrity at the lower voltage before implementation.

Q: What is the difference between the MFR Recommended and Parametric Equivalent substitutes?

A: AX7PAF1-1800.0000C (Parametric Equivalent) maintains all specifications of the original part, including 3.3V supply voltage. AX7PBF1-1800.0000C (MFR Recommended) operates at 2.5V. The parametric equivalent requires no circuit modifications, while the MFR recommended substitute requires voltage compatibility assessment.

Q: Are all three parts mechanically interchangeable?

A: Yes. All three parts share identical package specifications (8-SMD, No Lead), dimensions (7.00mm x 5.00mm), and height (1.90mm maximum). Mechanical interchangeability is confirmed. Electrical compatibility depends on supply voltage requirements.

Q: What compliance certifications apply to these parts?

A: All three parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. ECCN classification is EAR99 for all parts.

Q: Are there any frequency or stability differences between the substitutes?

A: No. All three parts operate at 1.8 GHz with ±25ppm frequency stability. Frequency and stability specifications are identical across all substitute options.
