Key Parameters

Substitute Part Grouping Explanation

Substitution for the AX7DBF4-150.0000C is determined by strict equivalence across the following critical parameters:

• Frequency: 150 MHz (exact match required)
• Output Type: LVDS (electrical interface specification)
• Supply Voltage: 2.5V (power requirement)
• Function: Enable/Disable (operational capability)
• Frequency Stability: ±25ppm (timing accuracy)
• Operating Temperature Range: -40°C ~ 85°C (environmental specification)
• Package Type: 8-SMD, No Lead (mechanical and thermal interface)
• Package Dimensions: 7.00mm x 5.00mm (footprint compatibility)

The AX7DBF1-150.0000C meets all these criteria and is classified as a parametric equivalent. Both parts belong to the Abracon LLC ClearClock™ AX7 series and share identical electrical and mechanical specifications.

Parameter Comparison

Frequently Asked Questions (FAQ)

Q: Can the AX7DBF1-150.0000C be used as a direct replacement for the AX7DBF4-150.0000C?

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

Q: Are there any differences in electrical performance between these two parts?

A: No. Both parts specify 150 MHz frequency, ±25ppm stability, 2.5V supply, 70mA maximum current, and LVDS output with enable/disable function.

Q: Do these parts have the same PCB footprint?

A: Yes. Both use the 8-SMD, No Lead package with identical dimensions of 7.00mm x 5.00mm and maximum seated height of 1.90mm.

Q: What is the significance of the different part number suffixes (DBF4 vs. DBF1)?

A: The suffix variation indicates different internal design revisions within the ClearClock™ AX7 series. Both revisions meet the same electrical and mechanical specifications for this frequency and output configuration.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 compliant, REACH unaffected, carry EAR99 classification, and have MSL 1 rating.
