Substitute Part Grouping Explanation

The AX5PAF3-400.0000T has one parametric equivalent substitute: AX5PAF1-400.0000T. This substitution is valid based on the following criteria:

Identical Electrical Parameters:

• Frequency: 400 MHz
• Output: LVPECL
• Supply Voltage: 3.3V
• Function: Enable/Disable
• Frequency Stability: ±20ppm
• Operating Temperature: -40°C ~ 85°C
• Maximum Supply Current: 110mA
• Disable Mode Current: 100mA

Identical Mechanical Parameters:

• Package Type: 8-SMD, No Lead
• Package Dimensions: 5.00mm x 3.20mm x 1.50mm (Max)
• Mounting Type: Surface Mount

Identical Compliance & Certifications:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected
• ECCN: EAR99
• HTSUS: 8542.39.0001

The primary difference between these parts is packaging format: AX5PAF3-400.0000T uses standard packaging, while AX5PAF1-400.0000T is supplied in Cut Tape (CT) & Digi-Reel® format.

Parameter Comparison

Engineering Selection Recommendations

Both AX5PAF3-400.0000T 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 and supply chain requirements:

• AX5PAF3-400.0000T: Use when standard packaging is required or preferred for inventory management. Currently 809 units in stock.
• AX5PAF1-400.0000T: Use when Cut Tape (CT) & Digi-Reel® packaging is specified for automated assembly processes. Currently 1197 units in stock.

Both parts are electrically and mechanically identical, with no functional differences in circuit performance, thermal characteristics, or compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can AX5PAF1-400.0000T be used as a direct replacement for AX5PAF3-400.0000T?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, frequency stability, operating temperature range, supply current, and package dimensions. The only difference is packaging format (Cut Tape & Digi-Reel® versus standard packaging).

Q: Are there any differences in frequency accuracy or stability between these parts?

A: No. Both parts maintain ±20ppm frequency stability across the -40°C ~ 85°C operating temperature range.

Q: Do both parts support Enable/Disable functionality?

A: Yes. Both AX5PAF3-400.0000T and AX5PAF1-400.0000T include Enable/Disable function with identical current specifications in both active (110mA max) and disable (100mA max) modes.

Q: What is the significance of the packaging format difference?

A: AX5PAF3-400.0000T uses standard packaging suitable for manual handling and general inventory. AX5PAF1-400.0000T uses Cut Tape (CT) & Digi-Reel® format optimized for automated pick-and-place assembly equipment. The choice depends on manufacturing process requirements, not electrical performance.

Q: Are both parts RoHS compliant?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Can these parts be used interchangeably in PCB designs?

A: Yes. Identical package type (8-SMD, No Lead), dimensions (5.00mm x 3.20mm x 1.50mm), and mounting type (Surface Mount) ensure direct PCB footprint compatibility.
