Key Parameters

Substitute Part Grouping Explanation

Substitution for the AX5DBF2-300.0000C is determined by strict equivalence across the following critical parameters:

• Frequency: 300 MHz
• Output Configuration: LVDS
• Supply Voltage: 2.5V
• Function: Enable/Disable capability
• Package Type: 8-SMD, No Lead
• Frequency Stability: ±20ppm
• Operating Temperature Range: -40°C ~ 85°C
• Current Specifications: 80mA maximum supply current, 70mA maximum disable current

The AX5DBF1-300.0000C meets all these criteria and is classified as a parametric equivalent. Both parts share identical electrical and mechanical specifications within the ClearClock™ AX5 series, differing only in internal design revision or manufacturing process while maintaining full functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

The AX5DBF1-300.0000C is a direct parametric equivalent to the AX5DBF2-300.0000C. Both parts maintain identical electrical performance, mechanical compatibility, and regulatory compliance. Selection between these parts is based on availability and procurement status rather than technical differentiation.

Both parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. The MSL 1 rating indicates unlimited shelf life under standard storage conditions, eliminating moisture-related constraints during procurement and assembly planning.

Current inventory status shows 708 units of the AX5DBF1-300.0000C available as new original stock, providing a viable supply source for applications currently using or requiring the discontinued AX5DBF2-300.0000C.

Frequently Asked Questions (FAQ)

Q: Can the AX5DBF1-300.0000C be used as a direct replacement for the AX5DBF2-300.0000C?

A: Yes. Both parts are parametric equivalents with identical frequency, output type, supply voltage, current specifications, package type, and operating temperature range. No circuit modifications are required.

Q: Are there any differences in pin configuration or package footprint?

A: No. Both parts use the same 8-SMD, No Lead package with identical dimensions of 5.00mm x 3.20mm x 1.50mm maximum height. PCB footprints are interchangeable.

Q: What is the significance of the different part number suffixes (DBF2 vs. DBF1)?

A: The suffix indicates an internal design revision or manufacturing process change within the ClearClock™ AX5 series. Both versions maintain full electrical and mechanical equivalence.

Q: Are both parts compliant with current environmental regulations?

A: Yes. Both the AX5DBF2-300.0000C and AX5DBF1-300.0000C are ROHS3 compliant and REACH unaffected.

Q: What is the MSL 1 rating and how does it affect handling?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life. These parts do not require special moisture control during storage or handling, simplifying procurement and assembly logistics.

Q: Can I use either part interchangeably in new designs?

A: Yes. For new designs, either part is acceptable. Selection should be based on current availability and supplier inventory status.
