Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AX5DBF3-400.0000C is determined by strict equivalence across the following critical parameters:

Frequency matching at 400 MHz, output configuration as LVDS, supply voltage of 2.5V, Enable/Disable function capability, frequency stability of ±20ppm, operating temperature range of -40°C to 85°C, maximum supply current of 80mA, maximum disable current of 70mA, and identical package specification of 8-SMD, No Lead with dimensions 5.00mm x 3.20mm x 1.50mm maximum height.

The AX5DBF1-400.0000C meets all these criteria and qualifies as a parametric equivalent within the ClearClock™ AX5 series.

Parameter Comparison

Engineering Selection Recommendations

The AX5DBF1-400.0000C serves as a direct parametric equivalent to the discontinued AX5DBF3-400.0000C. Both components maintain identical electrical specifications, mechanical packaging, and regulatory compliance status. The substitute part carries ROHS3 compliance and MSL 1 rating, matching the original specification. Current inventory availability of 851 units for the AX5DBF1-400.0000C supports procurement continuity for applications requiring this 400 MHz LVDS oscillator platform.

Frequently Asked Questions (FAQ)

Q: What determines if a part can substitute for the AX5DBF3-400.0000C?

A: Substitution requires exact matching across frequency (400 MHz), output type (LVDS), supply voltage (2.5V), function (Enable/Disable), frequency stability (±20ppm), operating temperature range (-40°C to 85°C), current specifications (80mA max supply, 70mA max disable), and package configuration (8-SMD, No Lead, 5.00mm x 3.20mm x 1.50mm).

Q: Are there differences between the AX5DBF3 and AX5DBF1 variants?

A: Both variants meet identical parametric specifications for this 400 MHz application. The difference in part number suffix does not affect electrical or mechanical compatibility within the stated parameters.

Q: Can this oscillator be used in new designs?

A: The AX5DBF3-400.0000C is discontinued at DiGi Electronics. The AX5DBF1-400.0000C provides equivalent functionality for both legacy support and new applications requiring 400 MHz LVDS oscillation at 2.5V.

Q: What is the significance of the 8-SMD, No Lead package?

A: This surface mount package type defines the PCB footprint and reflow soldering process. Substitutes must maintain identical package dimensions (5.00mm x 3.20mm x 1.50mm maximum height) to ensure mechanical fit and thermal performance.

Q: Are regulatory certifications maintained across substitutes?

A: Yes. Both the main part and substitute maintain ROHS3 compliance, MSL 1 rating, and REACH Unaffected status, ensuring regulatory continuity in applications subject to these standards.
