AX7MBF1-2000.0000C Equivalent & Substitute Parts

Part Overview

The AX7MBF1-2000.0000C is a 2 GHz XO (Standard) CML Oscillator manufactured by Abracon LLC as part of the ClearClock™ AX7 series. This surface mount crystal oscillator operates at 2.5V supply voltage 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 functionally equivalent alternatives necessary for ongoing design support and procurement.

Substitute Part Grouping Explanation

Substitution of the AX7MBF1-2000.0000C is determined by strict alignment of the following critical parameters:

• Frequency: 2 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 (exact match required)
• Frequency Stability: ±25ppm (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• RoHS Compliance: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

The AX7MCF1-2000.0000C 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 does not affect substitution eligibility when the application circuit is designed to accommodate the lower supply voltage requirement.

Parameter Comparison

Engineering Selection Recommendations

The AX7MCF1-2000.0000C is available as a substitute for the discontinued AX7MBF1-2000.0000C. Both parts maintain ROHS3 compliance and identical moisture sensitivity ratings, ensuring equivalent environmental and regulatory performance. The substitute part is currently in stock (993 Pcs New Original), providing immediate procurement availability.

Selection of the substitute requires verification that the application circuit design accommodates the 1.8V supply voltage specification. The mechanical footprint, electrical output characteristics (CML at 2 GHz), frequency stability (±25ppm), and thermal operating range remain identical between the two parts.

Frequently Asked Questions (FAQ)

Q: Can the AX7MCF1-2000.0000C directly replace the AX7MBF1-2000.0000C without circuit modification?

A: Direct replacement is possible only if the application circuit is designed to operate with a 1.8V supply voltage. The substitute part requires 1.8V operation, while the original part operates at 2.5V. Circuit redesign or voltage regulation adjustment may be necessary.

Q: Are the physical dimensions and package footprints identical?

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

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

A: Yes. Both parts are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), ensuring equivalent environmental performance and regulatory compliance.

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

A: Both the AX7MBF1-2000.0000C and AX7MCF1-2000.0000C 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 a maximum supply current of 68mA and maximum disable current of 67mA, indicating identical power consumption characteristics.
