Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AX7MBF3-2000.0000C must maintain compatibility across the following critical parameters:

• Frequency: 2 GHz (exact match required)
• Output Type: CML (exact match required)
• Function: Enable/Disable capability (exact match required)
• Package / Case: 8-SMD, No Lead (exact match required)
• Size / Dimension: 7.00mm x 5.00mm (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Frequency Stability: ±25ppm (exact match required)
• Series: ClearClock™ AX7 (same manufacturer series)
• RoHS Status: ROHS3 Compliant (compliance requirement)
• Moisture Sensitivity Level: 1 (Unlimited) (handling requirement)

The primary variable parameter that may differ between the main part and substitutes is Voltage - Supply, provided all other electrical and mechanical specifications remain identical. Substitutes operating at different supply voltages (such as 1.8V) are acceptable if the circuit design accommodates the voltage differential and all other parameters align exactly.

Parameter Comparison

Engineering Selection Recommendations

The AX7MCF1-2000.0000C is a qualified substitute for the AX7MBF3-2000.0000C based on identical electrical performance, mechanical compatibility, and regulatory compliance. Both parts are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory standards.

The primary design consideration is the supply voltage differential: the substitute operates at 1.8V compared to the main part's 2.5V. Selection of the AX7MCF1-2000.0000C requires verification that the circuit design supports 1.8V operation. If the original design mandates 2.5V supply voltage, the substitute is not suitable without circuit modification.

Both parts share identical frequency stability (±25ppm), operating temperature range (-40°C ~ 85°C), maximum supply current (68mA), and physical package specifications. The CML output type, Enable/Disable function, and 8-SMD, No Lead package ensure direct functional equivalence in applications where supply voltage compatibility is confirmed.

Frequently Asked Questions (FAQ)

Q: Can the AX7MCF1-2000.0000C replace the AX7MBF3-2000.0000C in any application?

A: The AX7MCF1-2000.0000C is electrically and mechanically compatible with the AX7MBF3-2000.0000C provided the circuit design operates at 1.8V supply voltage. If the original design requires 2.5V supply voltage, circuit modification is necessary before substitution.

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

A: The primary difference is supply voltage: AX7MBF3-2000.0000C operates at 2.5V, while AX7MCF1-2000.0000C operates at 1.8V. All other electrical and mechanical parameters are identical.

Q: Are both parts in the same package?

A: Yes. Both parts use the 8-SMD, No Lead package with identical dimensions (7.00mm x 5.00mm) and maximum seated height (1.90mm). They are mechanically interchangeable at the PCB level.

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: 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. They meet identical regulatory and environmental standards.

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

A: The AX7MCF1-2000.0000C has 993 pieces in stock as new original inventory, compared to 727 pieces for the main part. Both parts are discontinued at DiGi Electronics.
