Substitute Part Grouping Explanation

Substitute parts for the AX5DBF2-400.0000C are identified based on strict electrical and mechanical parameter matching. The following criteria determine substitutability:

Critical Parameters for Substitution:

• Frequency: 400 MHz (exact match required)
• Output Type: LVDS (exact match required)
• Supply Voltage: 2.5V (exact match required)
• Function: Enable/Disable (exact match required)
• Package Type: 8-SMD, No Lead (exact match required)
• Package Dimensions: 5.00mm x 3.20mm (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Frequency Stability: ±20ppm (exact match required)

The AX5DBF1-400.0000C meets all substitution criteria and is classified as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

The AX5DBF1-400.0000C serves as a direct parametric equivalent to the AX5DBF2-400.0000C. Both parts are manufactured by Abracon LLC within the ClearClock™ AX5 series and share identical electrical specifications, package geometry, and compliance certifications. The substitute part maintains ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with the original design.

Current inventory availability differs between the two parts, with the AX5DBF1-400.0000C showing 851 pieces in stock compared to 751 pieces for the main part. Both parts are discontinued at DiGi Electronics, indicating limited future availability through standard distribution channels.

Frequently Asked Questions (FAQ)

Q: Can the AX5DBF1-400.0000C be used as a direct replacement for the AX5DBF2-400.0000C?

A: Yes. The AX5DBF1-400.0000C is a parametric equivalent with identical electrical characteristics, frequency output, supply voltage, package type, and physical dimensions. No circuit modifications are required.

Q: Are there any differences in compliance or certifications between these parts?

A: No. Both parts maintain ROHS3 compliance, REACH unaffected status, and identical ECCN classification (EAR99). Regulatory requirements are equivalent.

Q: What is the significance of the different part numbers (AX5DBF2 vs. AX5DBF1)?

A: The part number suffix indicates internal design or manufacturing revision within the Abracon ClearClock™ AX5 series. Both variants meet the same electrical and mechanical specifications for 400 MHz LVDS oscillator applications.

Q: Are the package dimensions identical between the two parts?

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

Q: What should be considered given that both parts are discontinued?

A: Procurement planning should prioritize available inventory. The AX5DBF1-400.0000C currently has higher stock availability (851 pieces). For long-term designs, alternative 400 MHz LVDS oscillators from other manufacturers may require evaluation once current inventory is exhausted.
