Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AX7DBF1-425.0000C is determined by the following critical parameters:

• Frequency: 425 MHz (exact match required)
• Output Type: LVDS (exact match required)
• Package Type: 8-SMD, No Lead (exact match required)
• Package Dimensions: 7.00mm x 5.00mm footprint (exact match required)
• Function: Enable/Disable capability (exact match required)
• Frequency Stability: ±25ppm (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Supply Voltage: Functionally compatible if system design permits voltage adjustment or regulation
• Maximum Supply Current: 70mA (substitute must not exceed this value)
• Compliance: ROHS3 Compliant, MSL 1 rating

The AX7DCF1-425.0000C qualifies as a manufacturer-recommended substitute based on matching all critical parameters except supply voltage, which differs at 1.8V versus 2.5V for the primary part.

Parameter Comparison

Engineering Selection Recommendations

The AX7DCF1-425.0000C is designated as the manufacturer-recommended substitute for the discontinued AX7DBF1-425.0000C. Both parts maintain identical mechanical compatibility, electrical performance characteristics, and regulatory compliance status. The primary design consideration is supply voltage: the substitute operates at 1.8V versus the original 2.5V specification.

Selection of the substitute part requires verification that the system power supply architecture can accommodate 1.8V operation. If the original design utilizes dedicated 2.5V regulation, circuit modification or additional voltage conversion may be necessary. Both parts carry ROHS3 compliance and MSL 1 moisture sensitivity ratings, ensuring equivalent environmental and regulatory suitability for production and field deployment.

Frequently Asked Questions (FAQ)

Q: Can the AX7DCF1-425.0000C directly replace the AX7DBF1-425.0000C without circuit modification?

A: Direct replacement is possible only if the system design permits 1.8V supply voltage operation. If the original design requires 2.5V, power supply circuit modification is necessary.

Q: Are the package footprints identical between these parts?

A: Yes. Both parts use 8-SMD, No Lead packaging with identical 7.00mm x 5.00mm footprint and 1.90mm maximum seated height, ensuring PCB layout compatibility.

Q: Do both parts meet the same compliance and environmental standards?

A: Yes. Both parts are ROHS3 compliant with MSL 1 moisture sensitivity rating, meeting equivalent regulatory and environmental requirements.

Q: What is the frequency stability specification for both parts?

A: Both parts maintain ±25ppm frequency stability across the -40°C ~ 85°C operating temperature range.

Q: Are there differences in current consumption between the two parts?

A: No. Both parts specify 70mA maximum supply current and 65mA maximum disable mode current.

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

A: The supply voltage differs: AX7DBF1-425.0000C operates at 2.5V, while AX7DCF1-425.0000C operates at 1.8V. All other electrical and mechanical specifications are identical.
