AX7MBF1-425.0000C Equivalent & Substitute Parts

Part Overview

The AX7MBF1-425.0000C is a 425 MHz XO (Standard) CML Oscillator manufactured by Abracon LLC, part of the ClearClock™ AX7 series. This surface mount crystal oscillator operates at 2.5V with Enable/Disable functionality and is housed in an 8-SMD, No Lead package measuring 7.00mm x 5.00mm. The part is discontinued at DiGi Electronics, making identification of compatible substitute components essential for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AX7MBF1-425.0000C is determined by the following critical parameters:

• Frequency: 425 MHz (exact match required)
• Output Type: CML (exact match required)
• Package Type: 8-SMD, No Lead (exact match required)
• Package Dimensions: 7.00mm x 5.00mm (exact match required)
• Function: Enable/Disable (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Frequency Stability: ±25ppm (exact match required)

The AX7MCF1-425.0000C qualifies as a substitute based on matching all critical parameters. The primary difference is the supply voltage specification: the substitute operates at 1.8V versus the original part's 2.5V. This voltage difference requires circuit-level evaluation to determine compatibility with existing power supply infrastructure.

Parameter Comparison

Engineering Selection Recommendations

Both the AX7MBF1-425.0000C and AX7MCF1-425.0000C are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. Both parts maintain identical mechanical compatibility and thermal operating ranges. The substitute part AX7MCF1-425.0000C is currently available in inventory (1117 Pcs), whereas the original part is discontinued at DiGi Electronics.

Selection between these parts depends on circuit voltage compatibility. The 1.8V supply voltage of the substitute requires confirmation that the system power distribution can accommodate this lower voltage specification. If the design currently operates at 2.5V for this oscillator, voltage regulation or circuit modification may be necessary to implement the substitute part.

Frequently Asked Questions (FAQ)

Q: Can the AX7MCF1-425.0000C directly replace the AX7MBF1-425.0000C without circuit modifications?

A: Direct replacement is possible only if the system power supply can operate at 1.8V. The substitute part requires 1.8V supply voltage versus the original 2.5V. Verify that your power distribution network supports 1.8V operation before implementation.

Q: Are the package dimensions identical between these parts?

A: Yes. Both parts use the 8-SMD, No Lead package with dimensions of 7.00mm x 5.00mm and maximum seated height of 1.90mm. PCB footprints are mechanically compatible.

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

A: Yes. Both the AX7MBF1-425.0000C and AX7MCF1-425.0000C are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited). Both are REACH unaffected and carry the same ECCN and HTSUS classifications.

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

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

Q: Are there any differences in current consumption between these parts?

A: No. Both parts specify a maximum supply current of 68mA and maximum disable current of 67mA.
