AX7MBF3-1500.0000C Equivalent & Substitute Parts

Part Overview

The AX7MBF3-1500.0000C is a 1.5 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, 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 eligibility for the AX7MBF3-1500.0000C is determined by the following critical parameters:

• Frequency: 1.5 GHz (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 AX7MCF1-1500.0000C qualifies as a substitute part because it maintains identical specifications across all critical parameters. The sole difference is the supply voltage specification: the substitute operates at 1.8V instead of 2.5V. This voltage difference requires circuit-level evaluation to determine compatibility with the original design's power supply architecture.

Parameter Comparison

Engineering Selection Recommendations

Both the AX7MBF3-1500.0000C and AX7MCF1-1500.0000C are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. Both parts maintain identical mechanical compatibility and electrical performance characteristics across frequency, output type, stability, and thermal operating range.

The primary consideration for part selection is supply voltage compatibility. The main part operates at 2.5V, while the substitute operates at 1.8V. Selection between these parts depends on the power supply architecture of the target application. Both parts are discontinued at DiGi Electronics, indicating limited future availability through standard distribution channels.

Frequently Asked Questions (FAQ)

Q: Can the AX7MCF1-1500.0000C directly replace the AX7MBF3-1500.0000C?

A: Direct replacement requires verification that the application's power supply can accommodate 1.8V operation. The substitute part is electrically and mechanically compatible in all other respects, but voltage compatibility must be confirmed at the circuit design level.

Q: Are there any package or footprint differences between these parts?

A: No. Both parts use identical 8-SMD, No Lead packaging with dimensions of 7.00mm x 5.00mm and maximum seated height of 1.90mm. PCB footprints are interchangeable.

Q: Do both parts meet the same compliance standards?

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

Q: What is the frequency stability specification for these oscillators?

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

Q: Are there supply current differences between the main part and substitute?

A: No. Both parts specify maximum supply current of 68mA during normal operation and 67mA during disable mode.
