Substitute Part Grouping Explanation

Substitution of the AX7PAF3-1000.0000C is determined by strict equivalence across the following critical parameters:

• Frequency: 1 GHz (exact match required)
• Output Type: LVPECL (signal format compatibility)
• Supply Voltage: 3.3V (power supply compatibility)
• Function: Enable/Disable (functional feature match)
• Package / Case: 8-SMD, No Lead (PCB layout compatibility)
• Physical Dimensions: 0.276" L x 0.197" W, 0.075" max height (board space constraints)
• Frequency Stability: ±25ppm (timing accuracy specification)
• Operating Temperature Range: -40°C ~ 85°C (environmental operating limits)
• Current Specifications: Supply current 94mA max, disable current 86mA max (power budget compatibility)
• Compliance: ROHS3 Compliant, MSL 1 (regulatory and handling requirements)

Substitute parts must match all parameters listed above to ensure direct functional and mechanical compatibility without circuit redesign or board layout modification.

Parameter Comparison

Engineering Selection Recommendations

The AX7PAF1-1000.0000C is a parametric equivalent substitute for the AX7PAF3-1000.0000C. Both parts are manufactured by Abracon LLC within the ClearClock™ AX7 series and share identical electrical, mechanical, and compliance specifications. The substitute part maintains full compatibility with existing designs without requiring circuit modifications or PCB layout changes.

Both parts carry ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements. MSL 1 rating indicates unlimited shelf life under standard storage conditions. The discontinued status of both parts at DiGi Electronics reflects market availability rather than technical obsolescence.

Frequently Asked Questions (FAQ)

Q: Can the AX7PAF1-1000.0000C be used as a direct replacement for the AX7PAF3-1000.0000C?

A: Yes. The AX7PAF1-1000.0000C is a parametric equivalent with identical frequency (1 GHz), output type (LVPECL), supply voltage (3.3V), enable/disable function, package (8-SMD, No Lead), physical dimensions, frequency stability (±25ppm), operating temperature range (-40°C ~ 85°C), and current specifications. No circuit redesign or board layout modification is required.

Q: Are there any differences in compliance or handling between these parts?

A: No. Both parts are ROHS3 compliant, REACH Unaffected, and carry MSL 1 rating. Handling, storage, and compliance requirements are identical.

Q: What determines if a part can substitute for the AX7PAF3-1000.0000C?

A: Substitution requires exact matching of frequency (1 GHz), output type (LVPECL), supply voltage (3.3V), enable/disable function, package type (8-SMD, No Lead), physical dimensions (0.276" L x 0.197" W, 0.075" max height), frequency stability (±25ppm), operating temperature range (-40°C ~ 85°C), and current specifications (94mA max supply, 86mA max disable).

Q: Why are both parts discontinued at DiGi Electronics?

A: Product discontinuation at a distributor reflects inventory and market decisions rather than technical issues. Both parts remain functionally equivalent and suitable for design applications.

Q: Can I use a different frequency or output type oscillator as a substitute?

A: No. The 1 GHz frequency and LVPECL output type are critical to circuit operation. Substitutes must match these specifications exactly.
