Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AX5MBF2-322.265625C are identified based on the following critical parameters that must remain constant or compatible:

• Frequency: 322.265625 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)
• Size / Dimension: 0.197" L x 0.126" W (5.00mm x 3.20mm) (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Frequency Stability: ±20ppm (exact match required)
• Series: ClearClock™ AX5 (exact match required)

The substitute part AX5MCF1-322.265625C differs only in supply voltage (1.8V versus 2.5V), which represents a functional variation within the same product family. All other electrical and mechanical parameters remain identical.

Parameter Comparison

Engineering Selection Recommendations

Both parts maintain ROHS3 compliance and identical MSL ratings. The primary distinction is the supply voltage specification: AX5MBF2-322.265625C operates at 2.5V, while AX5MCF1-322.265625C operates at 1.8V. Selection between these parts depends on the power supply voltage available in the target application circuit. Both parts are discontinued at DiGi Electronics; component availability should be verified through authorized distributors prior to design implementation.

Frequently Asked Questions (FAQ)

Q: Can AX5MCF1-322.265625C replace AX5MBF2-322.265625C in an existing design?

A: Substitution is possible only if the application circuit can operate at 1.8V supply voltage instead of 2.5V. All other electrical and mechanical parameters are identical. Circuit redesign or voltage regulation modification may be required.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts use the same 8-SMD, No Lead package with dimensions of 0.197" L x 0.126" W (5.00mm x 3.20mm) and maximum seated height of 0.059" (1.50mm). PCB layout and footprints are interchangeable.

Q: What is the frequency stability specification for these oscillators?

A: Both parts maintain a frequency stability of ±20ppm across the operating temperature range of -40°C to 85°C.

Q: Are both parts RoHS compliant?

A: Yes. Both AX5MBF2-322.265625C and AX5MCF1-322.265625C are ROHS3 compliant with MSL rating of 1 (Unlimited).

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

A: Both parts specify a maximum supply current of 85mA under normal operating conditions.
