Substitute Part Grouping Explanation

The AX5PAF1-500.0000T qualifies as a parametric equivalent to the AX5PAF4-500.0000T based on strict alignment of critical electrical and mechanical specifications. Both parts maintain identical frequency (500 MHz), output type (LVPECL), supply voltage (3.3V), frequency stability (±20ppm), operating temperature range (-40°C ~ 85°C), maximum supply current (110mA), and package configuration (8-SMD, No Lead with 5.00mm x 3.20mm x 1.50mm dimensions). The substitution is valid because all functional parameters, compliance certifications (ROHS3, REACH Unaffected), and physical form factors are equivalent. The primary difference is packaging format: AX5PAF4-500.0000T uses standard packaging, while AX5PAF1-500.0000T is supplied in Cut Tape (CT) & Digi-Reel® format.

Parameter Comparison

Engineering Selection Recommendations

Both the AX5PAF4-500.0000T and AX5PAF1-500.0000T 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. The AX5PAF4-500.0000T is suitable for applications requiring standard packaging with 705 units currently in stock. The AX5PAF1-500.0000T, available in Cut Tape (CT) & Digi-Reel® format with 1009 units in stock, is appropriate for high-volume automated assembly processes. Both parts are electrically and mechanically interchangeable for the specified 500 MHz LVPECL oscillator application.

Frequently Asked Questions (FAQ)

Q: Can AX5PAF1-500.0000T replace AX5PAF4-500.0000T in my circuit?

A: Yes. Both parts are parametric equivalents with identical electrical specifications (500 MHz, LVPECL output, 3.3V supply, ±20ppm stability, -40°C ~ 85°C operating range) and mechanical form factor (8-SMD, No Lead, 5.00mm x 3.20mm x 1.50mm). The only difference is packaging format.

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

A: The AX5PAF4-500.0000T uses standard packaging, while the AX5PAF1-500.0000T is supplied in Cut Tape (CT) & Digi-Reel® format. This affects handling and assembly processes but does not impact electrical or mechanical performance.

Q: Are both parts ROHS3 compliant?

A: Yes. Both AX5PAF4-500.0000T and AX5PAF1-500.0000T are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the moisture sensitivity level for these oscillators?

A: Both parts have Moisture Sensitivity Level (MSL) 1, which indicates unlimited shelf life without moisture control requirements.

Q: Can I use these parts interchangeably on the same PCB?

A: Yes. Both parts have identical package dimensions (5.00mm x 3.20mm) and 8-SMD, No Lead configuration, allowing direct PCB footprint compatibility. The substitution is valid for circuit design and layout purposes.
