Key Parameters

Substitute Part Grouping Explanation

Substitution of the AX7MBF2-425.0000C is determined by the following critical parameters:

• Frequency: 425 MHz (exact match required)
• Output Type: CML (exact match required)
• Package / Case: 8-SMD, No Lead (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Frequency Stability: ±25ppm (exact match required)
• Function: Enable/Disable (exact match required)
• Series: ClearClock™ AX7 (same product family)

The AX7MCF1-425.0000C qualifies as a manufacturer-recommended substitute. While the supply voltage differs (1.8V vs. 2.5V), all other electrical and mechanical parameters remain identical. This voltage difference represents the primary design consideration for substitution eligibility.

Parameter Comparison

Engineering Selection Recommendations

The AX7MCF1-425.0000C is the manufacturer-recommended substitute for the discontinued AX7MBF2-425.0000C. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment. The primary design consideration is the supply voltage reduction from 2.5V to 1.8V. Circuit designs must accommodate this voltage specification to ensure proper oscillator operation and signal integrity. Both parts share identical package geometry, frequency output, and thermal operating range, enabling direct mechanical and functional substitution when voltage requirements are met.

Frequently Asked Questions (FAQ)

Q: Can the AX7MCF1-425.0000C be used as a direct replacement for the AX7MBF2-425.0000C?

A: The AX7MCF1-425.0000C is electrically and mechanically compatible with the AX7MBF2-425.0000C for all parameters except supply voltage. Direct substitution is possible only if the circuit design operates at 1.8V. If the original design requires 2.5V operation, voltage regulation or circuit modification is necessary.

Q: What is the primary difference between these two parts?

A: The supply voltage differs: AX7MBF2-425.0000C operates at 2.5V, while AX7MCF1-425.0000C operates at 1.8V. All other specifications—frequency, output type, package, temperature range, and frequency stability—are identical.

Q: Are both parts in the same package?

A: Yes. Both parts use the 8-SMD, No Lead package with identical dimensions of 7.00mm x 5.00mm x 1.90mm (Max Height), enabling direct PCB footprint compatibility.

Q: Do both parts have the same frequency stability?

A: Yes. Both parts maintain ±25ppm frequency stability across the -40°C ~ 85°C operating temperature range.

Q: What is the inventory status of the substitute part?

A: The AX7MCF1-425.0000C has 1117 pieces in stock as new original inventory, compared to 754 pieces for the main part.
