Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AX7MBF2-1500.0000C is determined by the following critical parameters:

• Frequency: 1.5 GHz (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 AX7MCF1-1500.0000C qualifies as a manufacturer-recommended substitute. While the supply voltage differs (1.8V versus 2.5V), this represents a valid substitution pathway when the application circuit is designed to accommodate the lower voltage specification. Both parts share identical frequency, output type, function, package configuration, and thermal characteristics.

Parameter Comparison

Engineering Selection Recommendations

The AX7MCF1-1500.0000C is the manufacturer-recommended substitute for the discontinued AX7MBF2-1500.0000C. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment. The primary design consideration is the supply voltage differential: the substitute operates at 1.8V compared to the original 2.5V specification. Selection of the AX7MCF1-1500.0000C requires confirmation that the application power supply and signal conditioning circuitry support 1.8V operation. Identical package footprint, frequency, output type, and thermal characteristics ensure mechanical and functional compatibility when voltage requirements are satisfied.

Frequently Asked Questions (FAQ)

Q: Can the AX7MCF1-1500.0000C be used as a direct drop-in replacement for the AX7MBF2-1500.0000C?

A: Physical and functional compatibility is confirmed. The substitute shares identical package configuration (8-SMD, No Lead), frequency (1.5 GHz), output type (CML), and thermal range (-40°C ~ 85°C). The supply voltage difference (1.8V versus 2.5V) requires circuit-level evaluation to confirm compatibility with existing power distribution and signal conditioning.

Q: What are the critical parameters that must match for substitution?

A: Frequency, output type, function, package configuration, physical dimensions, operating temperature range, and frequency stability must remain constant. The AX7MCF1-1500.0000C maintains all these parameters identically to the original part.

Q: Are there compliance or certification differences between these parts?

A: Both parts carry identical RoHS3 compliance and REACH unaffected status. Moisture sensitivity level (MSL 1 - Unlimited) is equivalent, ensuring identical handling and storage requirements.

Q: What is the primary design consideration when selecting the substitute?

A: The 1.8V supply voltage specification of the AX7MCF1-1500.0000C requires verification that the application circuit is designed to operate at this lower voltage level. Current consumption (68mA maximum) remains unchanged.
