Key Parameters

Substitute Part Grouping Explanation

Substitution of the AX7MBF2-2000.0000C is determined by the following critical parameters:

• Frequency: Must be 2.0000 GHz (exact match required)
• Output Type: Must be CML (CMOS/ECL compatible logic)
• Package Type: Must be 8-SMD, No Lead (mechanical and electrical compatibility)
• Operating Temperature Range: Must support -40°C to 85°C minimum
• Frequency Stability: Must meet ±25ppm specification
• Function: Must include Enable/Disable capability
• Series: ClearClock™ AX7 series preferred for design continuity

The AX7MCF1-2000.0000C qualifies as a manufacturer-recommended substitute. While the supply voltage differs (1.8V vs. 2.5V), this represents a valid substitution path when the application circuit can accommodate the lower voltage specification. All other critical parameters—frequency, output type, package, temperature range, stability, and function—remain identical.

Parameter Comparison

Engineering Selection Recommendations

Both parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. The AX7MCF1-2000.0000C is the manufacturer-recommended substitute and maintains identical mechanical compatibility and electrical performance characteristics across all parameters except supply voltage.

Selection between these parts depends on circuit design specifications. The 2.5V variant (AX7MBF2-2000.0000C) is suitable for systems with 2.5V supply rails, while the 1.8V variant (AX7MCF1-2000.0000C) is appropriate for lower-voltage applications. Both parts share the same package footprint, thermal characteristics, and frequency stability performance.

Frequently Asked Questions (FAQ)

Q: Can the AX7MCF1-2000.0000C directly replace the AX7MBF2-2000.0000C?

A: Direct replacement is possible only if the application circuit supports 1.8V supply voltage operation. The lower voltage specification does not affect frequency, output type, package compatibility, or thermal performance. Circuit validation is required to confirm voltage compatibility.

Q: Are the package dimensions identical between these parts?

A: Yes. Both parts use the 8-SMD, No Lead package with identical dimensions of 7.00mm length, 5.00mm width, and 1.90mm maximum height. PCB footprints are interchangeable.

Q: Do both parts meet the same frequency stability specification?

A: Yes. Both the AX7MBF2-2000.0000C and AX7MCF1-2000.0000C maintain ±25ppm frequency stability across the -40°C to 85°C operating temperature range.

Q: What is the significance of the CML output type?

A: CML (Current Mode Logic) output is a high-speed signaling standard suitable for RF and high-frequency applications. Both substitute parts provide identical CML output characteristics at 2.0000 GHz.

Q: Are there any moisture sensitivity concerns with these parts?

A: Both parts carry MSL Rating 1 (Unlimited), indicating no moisture sensitivity limitations. Standard handling procedures apply without special dry-pack requirements.

Q: How do the Enable/Disable functions compare between these parts?

A: Both parts include Enable/Disable functionality with identical current specifications: 68mA maximum during operation and 67mA maximum in disable mode.
