Substitute Part Grouping Explanation

The AX5PAF2-400.0000T has one identified parametric equivalent: AX5PAF1-400.0000T. This substitution is valid based on the following critical parameters that remain identical across both parts:

• Frequency: 400 MHz
• Output Type: LVPECL
• Supply Voltage: 3.3V
• Function: Enable/Disable
• Frequency Stability: ±20ppm
• Operating Temperature Range: -40°C ~ 85°C
• Current - Supply (Max): 110mA
• Current - Supply (Disable) (Max): 100mA
• Mounting Type: Surface Mount
• Package / Case: 8-SMD, No Lead
• Physical Dimensions: 0.197" L x 0.126" W (5.00mm x 3.20mm)
• Height - Seated (Max): 0.059" (1.50mm)
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

The primary difference between these parts is packaging configuration: AX5PAF2-400.0000T is supplied in standard packaging, while AX5PAF1-400.0000T is available in Cut Tape (CT) & Digi-Reel® packaging. Both parts belong to the same ClearClock™ AX5 series and maintain identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both AX5PAF2-400.0000T and AX5PAF1-400.0000T are Active products from Abracon LLC with full ROHS3 compliance and REACH Unaffected status. Selection between these parts should be based on packaging requirements and supply availability:

• AX5PAF2-400.0000T: Select when standard packaging is required or preferred for inventory management.
• AX5PAF1-400.0000T: Select when Cut Tape (CT) & Digi-Reel® packaging is required for automated assembly processes or when higher inventory availability is needed.

Both parts maintain identical electrical performance, thermal characteristics, and mechanical compatibility. No functional differences exist between these oscillators.

Frequently Asked Questions (FAQ)

Q: Can AX5PAF1-400.0000T be used as a direct replacement for AX5PAF2-400.0000T?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, frequency output, supply voltage, current consumption, operating temperature range, and physical dimensions. The only difference is packaging format.

Q: What is the difference between the packaging formats?

A: AX5PAF2-400.0000T uses standard packaging, while AX5PAF1-400.0000T is supplied in Cut Tape (CT) & Digi-Reel® format. Cut Tape packaging is optimized for automated pick-and-place assembly equipment, while standard packaging is suitable for manual handling and general inventory storage.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts deliver identical frequency stability (±20ppm), output type (LVPECL), supply voltage (3.3V), and current consumption characteristics. They are functionally interchangeable.

Q: Do both parts meet the same compliance standards?

A: Yes. Both AX5PAF2-400.0000T and AX5PAF1-400.0000T are ROHS3 Compliant, REACH Unaffected, and classified as MSL 1 (Unlimited moisture sensitivity level).

Q: Which part should I select for my design?

A: Selection depends on your assembly process and supply chain requirements. For automated assembly lines, Cut Tape (CT) & Digi-Reel® packaging (AX5PAF1-400.0000T) is recommended. For manual assembly or when standard packaging is preferred, select AX5PAF2-400.0000T. Both parts are electrically and mechanically identical.
