Key Parameters

Substitute Part Grouping Explanation

Substitution of the AX7MBF1-1500.0000C is determined by strict alignment of the following critical parameters:

Fixed Requirements (Non-Negotiable):

• Frequency: 1.5 GHz
• Output Type: CML
• Function: Enable/Disable
• Package / Case: 8-SMD, No Lead
• Size / Dimension: 7.00mm x 5.00mm
• Height - Seated (Max): 1.90mm
• Operating Temperature Range: -40°C ~ 85°C
• Frequency Stability: ±25ppm

Variable Parameters (Allowed Variance):

• Voltage - Supply: Different supply voltage ratings are acceptable if the substitute operates within the system's available voltage rails
• Current - Supply (Max): Variations within the same series are permissible provided the substitute does not exceed system power budgets

The AX7MCF1-1500.0000C qualifies as a direct substitute based on identical frequency, output type, package, dimensions, temperature range, and frequency stability. The primary difference is the supply voltage specification (1.8V vs. 2.5V), which represents a valid substitution path for systems designed to operate at lower voltage rails.

Parameter Comparison

Engineering Selection Recommendations

The AX7MCF1-1500.0000C serves as a qualified substitute for the discontinued AX7MBF1-1500.0000C. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment. The substitute maintains identical mechanical compatibility, frequency performance, and thermal operating range.

Selection between these parts depends on system voltage architecture. The AX7MBF1-1500.0000C operates at 2.5V, while the AX7MCF1-1500.0000C operates at 1.8V. Verify that your circuit design accommodates the substitute's supply voltage specification before implementation. Both parts are available in current inventory through authorized distributors.

Frequently Asked Questions (FAQ)

Q: Can the AX7MCF1-1500.0000C replace the AX7MBF1-1500.0000C in existing designs?

A: Yes, provided your circuit design operates at 1.8V supply voltage. The substitute maintains identical frequency, output type, package dimensions, and thermal specifications. Verify power supply compatibility before substitution.

Q: Are there mechanical compatibility concerns between these parts?

A: No. Both parts use the 8-SMD, No Lead package with identical dimensions (7.00mm x 5.00mm) and maximum seated height (1.90mm). PCB footprints and assembly processes remain unchanged.

Q: What is the primary difference between these oscillators?

A: The supply voltage specification differs. The AX7MBF1-1500.0000C requires 2.5V, while the AX7MCF1-1500.0000C operates at 1.8V. All other electrical and mechanical parameters remain identical.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity ratings.

Q: What should I verify before implementing the substitute?

A: Confirm that your system power supply can provide 1.8V to the substitute oscillator. Verify that the Enable/Disable control logic remains compatible with the CML output type. Confirm PCB layout accommodates the 8-SMD, No Lead package footprint.
