Key Parameters

Substitute Part Grouping Explanation

Substitution of the AX7MBF2-622.0800C is determined by the following critical parameters:

• 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)
• Physical Dimensions: 7.00mm x 5.00mm footprint (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Frequency Stability: ±25ppm (exact match required)

The AX7MCF1-622.0800C qualifies as a manufacturer-recommended substitute. While the supply voltage differs (1.8V vs. 2.5V), this represents a valid alternative within the ClearClock™ AX7 series, maintaining all other critical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the AX7MBF2-622.0800C and AX7MCF1-622.0800C are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. The primary distinction is the supply voltage specification: 2.5V for the main part and 1.8V for the substitute.

Selection between these parts depends on circuit design requirements. If the application circuit operates at 2.5V, the AX7MBF2-622.0800C is the direct specification match. If the application circuit operates at 1.8V or supports dual voltage operation, the AX7MCF1-622.0800C is the appropriate selection. Both parts maintain identical frequency, output type, package, and thermal characteristics.

Frequently Asked Questions (FAQ)

Q: Can the AX7MCF1-622.0800C replace the AX7MBF2-622.0800C in all applications?

A: Substitution is valid only if the application circuit supports 1.8V operation. The supply voltage difference is the only electrical distinction between these parts. All other parameters—frequency, output type, function, stability, and thermal range—are identical.

Q: Are the physical footprints identical?

A: Yes. Both parts use the 8-SMD, No Lead package with identical dimensions of 7.00mm x 5.00mm and maximum seated height of 1.90mm. PCB layout and reflow profiles remain unchanged.

Q: What is the significance of the frequency stability specification?

A: Both parts maintain ±25ppm frequency stability across the -40°C ~ 85°C operating temperature range. This specification ensures consistent oscillator performance and is identical between the main part and substitute.

Q: Are there any compliance differences between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. Regulatory and environmental compliance is equivalent.

Q: Why is the main part discontinued?

A: Product discontinuation at DiGi Electronics does not affect the technical validity of the part. The AX7MCF1-622.0800C remains available as a manufacturer-recommended alternative within the same series.
