Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AX7MBF1-622.0800C are identified based on the following critical parameters that determine functional compatibility:

• Frequency: 622.08 MHz (exact match required)
• Output Type: CML (exact match required)
• Function: Enable/Disable (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)
• Series: ClearClock™ AX7 (same product family)

The primary difference between the main part and substitute parts lies in the supply voltage specification. The AX7MBF1-622.0800C operates at 2.5V, while substitute parts may operate at different voltage levels. Voltage compatibility must be verified against the target application's power supply specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the AX7MBF1-622.0800C and AX7MCF1-622.0800C are discontinued at DiGi Electronics. Selection between these parts depends on application power supply requirements:

The AX7MBF1-622.0800C operates at 2.5V supply voltage and is suitable for applications with 2.5V power rails. The AX7MCF1-622.0800C operates at 1.8V supply voltage and is suitable for applications with 1.8V power rails. Both parts maintain identical frequency, output type, stability, temperature range, and package specifications.

Both parts are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements. Moisture Sensitivity Level 1 (Unlimited) indicates no special moisture handling precautions are required during storage or assembly.

Frequently Asked Questions (FAQ)

Q: Can the AX7MCF1-622.0800C replace the AX7MBF1-622.0800C in my design?

A: Substitution is possible only if your application power supply operates at 1.8V. If your design requires 2.5V operation, the AX7MCF1-622.0800C is not compatible. All other electrical and mechanical parameters are identical.

Q: Are the package dimensions identical between these parts?

A: Yes. Both parts use the same 8-SMD, No Lead package with dimensions of 0.276" L x 0.197" W (7.00mm x 5.00mm) and maximum seated height of 0.075" (1.90mm). PCB layout and assembly processes remain unchanged.

Q: What is the frequency stability specification, and does it differ between parts?

A: Both parts specify ±25ppm frequency stability across the operating temperature range of -40°C to 85°C. Frequency stability is identical between the main part and substitute.

Q: Are there any compliance or regulatory differences between these oscillators?

A: No. Both parts are ROHS3 Compliant, REACH Unaffected, and carry identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications. Regulatory status is equivalent.

Q: What is the maximum supply current for these oscillators?

A: Both parts specify a maximum supply current of 68mA during normal operation and 67mA during disable mode. Current consumption is identical between the two parts.
