AX7PAF1-2000.0000 Equivalent & Substitute Parts

Part Overview

The AX7PAF1-2000.0000 is a 2 GHz XO (Standard) LVPECL Oscillator manufactured by Abracon LLC as part of the ClearClock™ AX7 series. This surface-mount crystal oscillator operates at 3.3V with enable/disable functionality, designed for applications requiring stable 2 GHz frequency output in LVPECL logic levels. The part is currently active in production with 767 units in stock. Substitute parts become necessary when primary inventory is unavailable, when design revisions require alternative sourcing, or when supply chain constraints impact procurement timelines.

Substitute Part Grouping Explanation

Substitution eligibility for the AX7PAF1-2000.0000 is determined by strict equivalence across the following critical parameters:

• Frequency: 2 GHz (exact match required)
• Output Logic Level: LVPECL (no alternative logic families acceptable)
• Supply Voltage: 3.3V (no voltage variants acceptable)
• Enable/Disable Function: Required (functional equivalence)
• Frequency Stability: ±25ppm (tolerance match required)
• Operating Temperature Range: -40°C ~ 85°C (full range required)
• Package Type: 8-SMD, No Lead (mechanical compatibility required)
• Package Dimensions: 7.00mm x 5.00mm footprint (PCB layout compatibility)
• Compliance: ROHS3 Compliant, MSL 1 (regulatory and handling equivalence)

Only parts meeting all these parameters qualify as direct substitutes. Parametric equivalents within the same manufacturer series that share identical electrical and mechanical specifications are listed below.

Engineering Selection Recommendations

Primary Selection: AX7PAF1-2000.0000 is the recommended choice for new designs and procurement. This part maintains active production status with established supply availability and full manufacturer support.

Substitute Selection: AX7PAF1-2000.0000C is a parametric equivalent suitable for direct replacement in existing designs where the primary part is unavailable. All electrical and mechanical specifications are identical. However, this part is discontinued at DiGi Electronics, indicating limited future availability. Selection of this substitute should be accompanied by inventory verification and long-term supply chain assessment.

Compliance Basis: Both parts maintain ROHS3 compliance and MSL 1 rating, ensuring regulatory equivalence and identical handling requirements for manufacturing and storage.

Frequently Asked Questions (FAQ)

Q: Can AX7PAF1-2000.0000C be used as a direct replacement for AX7PAF1-2000.0000?

A: Yes. Both parts are parametrically equivalent across all critical electrical and mechanical specifications: 2 GHz frequency, LVPECL output, 3.3V supply, ±25ppm stability, 8-SMD package, and identical dimensions. Pin-for-pin compatibility and functional equivalence are confirmed.

Q: What is the difference between these two part numbers?

A: The suffix "C" in AX7PAF1-2000.0000C indicates a variant designation within the ClearClock™ AX7 series. Both parts share identical electrical performance and package specifications. The primary distinction is product status: AX7PAF1-2000.0000 is active in production, while AX7PAF1-2000.0000C is discontinued at DiGi Electronics.

Q: Are there any PCB layout considerations when substituting these parts?

A: No. Both parts use the identical 8-SMD, No Lead package with 7.00mm x 5.00mm footprint and 1.90mm maximum seated height. PCB layouts, footprints, and assembly processes require no modification.

Q: What are the handling and storage requirements for these oscillators?

A: Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. Standard ESD precautions and room-temperature storage are sufficient. No special desiccant or controlled humidity storage is required.

Q: Can these parts be used in applications requiring extended temperature ranges beyond -40°C ~ 85°C?

A: No. Both parts are specified for -40°C ~ 85°C operating temperature range only. Applications requiring extended temperature operation require alternative part selection outside this series.

Q: What is the current consumption difference between enabled and disabled states?

A: Maximum supply current in enabled state is 94mA. Maximum supply current in disabled state is 86mA. The 8mA difference represents the oscillator core consumption when the enable/disable function is activated.
