Key Parameters

Substitute Part Grouping Explanation

Substitution for the AX7PAF2-1500.0000C is determined by the following critical parameters:

• Frequency: 1.5 GHz (exact match required)
• Output Type: LVPECL (exact match required)
• Package / Case: 8-SMD, No Lead (exact match required)
• Physical Dimensions: 7.00mm x 5.00mm footprint (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Frequency Stability: ±25ppm (exact match required)
• Function: Enable/Disable (exact match required)
• Series: ClearClock™ AX7 (exact match required)

Substitute parts are identified based on matching all critical electrical and mechanical parameters. The primary variable among substitutes is the supply voltage specification, which determines circuit compatibility within the design application.

Engineering Selection Recommendations

AX7PBF1-1500.0000C (MFR Recommended Substitute)

This part is the manufacturer-recommended substitute for the AX7PAF2-1500.0000C. It maintains identical electrical performance, frequency stability, and mechanical compatibility. The primary difference is the reduced supply voltage specification of 2.5V versus 3.3V. This substitute is applicable only in designs where the power supply rail is 2.5V or where the circuit topology supports operation at the lower voltage. Current inventory availability is 985 Pcs.

AX7PAF1-1500.0000C (Parametric Equivalent)

This part is a parametric equivalent that matches the main part in all critical specifications, including the 3.3V supply voltage requirement. It provides direct functional and mechanical compatibility with identical electrical characteristics. Current inventory availability is 961 Pcs. This part is suitable for direct substitution in designs requiring 3.3V operation.

Both substitute parts maintain ROHS3 compliance, MSL 1 rating, and identical package dimensions, ensuring PCB layout compatibility without redesign.

Frequently Asked Questions (FAQ)

Q: Can AX7PBF1-1500.0000C be used as a direct replacement for AX7PAF2-1500.0000C?

A: AX7PBF1-1500.0000C is the manufacturer-recommended substitute but operates at 2.5V supply voltage instead of 3.3V. Direct substitution is possible only if your circuit design operates at 2.5V or supports dual-voltage operation. If your design requires 3.3V operation, use AX7PAF1-1500.0000C instead.

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

A: AX7PBF1-1500.0000C is the manufacturer's recommended alternative with a 2.5V supply voltage specification. AX7PAF1-1500.0000C is a parametric equivalent that maintains the original 3.3V supply voltage. Both parts are electrically and mechanically identical except for the supply voltage rating.

Q: Are all three parts pin-compatible?

A: Yes. All three parts use the identical 8-SMD, No Lead package with 7.00mm x 5.00mm footprint and 1.90mm maximum seated height. PCB layout and footprint are interchangeable without modification.

Q: Do these substitutes maintain the same frequency stability?

A: Yes. All three parts specify ±25ppm frequency stability across the -40°C ~ 85°C operating temperature range.

Q: Are there any compliance or certification differences?

A: No. All three parts are ROHS3 compliant, carry MSL 1 (Unlimited) moisture sensitivity rating, and are REACH Unaffected with identical ECCN and HTSUS classifications.

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

A: If your power supply is 3.3V, select AX7PAF1-1500.0000C. If your power supply is 2.5V, select AX7PBF1-1500.0000C. Both parts are currently available in inventory and are discontinued at DiGi Electronics, so procurement should be prioritized accordingly.
