Substitute Part Grouping Explanation

Substitution for the AX7PAF2-2000.0000C is determined by the following critical parameters:

Primary Substitution Criteria (Must Match):

Frequency: 2 GHz
Output Type: LVPECL
Package Type: 8-SMD, No Lead
Mounting Type: Surface Mount
Operating Temperature Range: -40°C to 85°C
Frequency Stability: ±25ppm

Secondary Substitution Criteria (Allowable Variation):

Supply Voltage: 3.3V (primary) or 2.5V (alternative)
Current specifications: 94mA maximum supply current
Physical dimensions: 7.00mm x 5.00mm footprint with 1.90mm maximum height

The substitute parts identified fall into two categories: parametric equivalents operating at 3.3V and manufacturer-recommended alternatives operating at 2.5V. All substitutes maintain identical frequency, output type, package configuration, and thermal specifications.

Engineering Selection Recommendations

Direct Parametric Equivalent (3.3V Supply): AX7PAF1-2000.0000 is the primary substitute for the AX7PAF2-2000.0000C. This part maintains identical electrical and mechanical specifications while offering active product status, ensuring long-term availability and supply chain continuity. Both parts operate at 3.3V and are functionally interchangeable in designs requiring this supply voltage.

Alternative Supply Voltage Options (2.5V Supply): AX7PBF1-2000.0000C and AX7PBF3-2000.0000C are manufacturer-recommended alternatives that maintain all critical parameters except supply voltage, which operates at 2.5V instead of 3.3V. These parts are suitable only for designs with 2.5V power rails or where voltage regulation can accommodate the lower supply requirement.

Compliance and Certification: All substitute parts maintain ROHS3 compliance, REACH unaffected status, and MSL 1 rating, ensuring compatibility with current manufacturing and environmental standards.

Frequently Asked Questions (FAQ)

Q: Can AX7PAF1-2000.0000 directly replace AX7PAF2-2000.0000C? A: Yes. AX7PAF1-2000.0000 is a direct parametric equivalent with identical frequency, output type, supply voltage, package configuration, and thermal specifications. The primary advantage is active product status.

Q: What is the difference between the 3.3V and 2.5V substitute options? A: The AX7PAF1-2000.0000 and AX7PAF1-2000.0000C operate at 3.3V, matching the original part's supply voltage. The AX7PBF1-2000.0000C and AX7PBF3-2000.0000C operate at 2.5V and are suitable only for designs with 2.5V power supplies or where voltage regulation is implemented.

Q: Are all substitute parts pin-compatible? A: Yes. All substitute parts use the same 8-SMD, No Lead package with identical 7.00mm x 5.00mm footprint and 1.90mm maximum height, ensuring direct PCB layout compatibility.

Q: Do the substitute parts maintain the same frequency stability? A: Yes. All substitute parts maintain ±25ppm frequency stability, identical to the original AX7PAF2-2000.0000C.

Q: What is the significance of product status (Active vs. Discontinued)? A: Active status indicates ongoing manufacturing and supply availability. AX7PAF1-2000.0000 is the only active substitute, providing the best long-term supply chain assurance for new designs or production runs.

Q: Are there any differences in current consumption between substitutes? A: No. All substitute parts maintain 94mA maximum supply current and 86mA disable mode current, identical to the original part.

Q: Can these parts be used interchangeably in high-frequency applications? A: Yes, provided the supply voltage requirement is met. All parts maintain identical 2 GHz frequency, LVPECL output, and ±25ppm stability across the -40°C to 85°C operating range.
