Substitute Part Grouping Explanation

Substitution for the AX7MCF4-2100.0000C is determined by strict equivalence across the following critical parameters:

• Frequency: 2.1 GHz (exact match required)
• Output Configuration: CML (exact match required)
• Supply Voltage: 1.8V (exact match required)
• Function: Enable/Disable capability (exact match required)
• Package Type: 8-SMD, No Lead (exact match required)
• Package Dimensions: 7.00mm x 5.00mm footprint (exact match required)
• Frequency Stability: ±25ppm (exact match required)
• Operating Temperature: -40°C ~ 85°C (exact match required)

The AX7MCF1-2100.0000C meets all substitution criteria as a parametric equivalent within the Abracon ClearClock™ AX7 series.

Frequently Asked Questions (FAQ)

Q: Can the AX7MCF1-2100.0000C be used as a direct replacement for the AX7MCF4-2100.0000C?

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

Q: Are there any differences in pin configuration or footprint between these parts?

A: No. Both components use the same 8-SMD, No Lead package with identical 7.00mm x 5.00mm footprint and 1.90mm maximum seated height. PCB layout and assembly processes remain unchanged.

Q: Do both parts meet the same compliance and environmental standards?

A: Yes. Both the AX7MCF4-2100.0000C and AX7MCF1-2100.0000C are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the significance of the different part number suffixes (MCF4 vs. MCF1)?

A: The suffix variation indicates internal design or manufacturing process differences within the Abracon ClearClock™ AX7 series. These differences do not affect electrical performance or mechanical compatibility for end-use applications.

Q: Are there any supply current or thermal considerations when substituting these parts?

A: No. Both parts specify identical maximum supply current (68mA), disable current (67mA), and operating temperature range (-40°C ~ 85°C). Thermal and power management designs require no modification.
