AX7MBF4-1500.0000C Equivalent & Substitute Parts

Part Overview

The AX7MBF4-1500.0000C 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.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AX7MBF4-1500.0000C 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 (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Frequency Stability: ±25ppm (exact match required)
• Series: ClearClock™ AX7 (same product family)

The AX7MCF1-1500.0000C qualifies as a substitute part. While the supply voltage differs (1.8V versus 2.5V), this represents a valid alternative within the same product family and package specification, provided the application circuit supports 1.8V operation.

Parameter Comparison

Engineering Selection Recommendations

The AX7MCF1-1500.0000C is available as a substitute for the discontinued AX7MBF4-1500.0000C. Both parts maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for current procurement. The primary design consideration is the supply voltage difference: the substitute operates at 1.8V rather than 2.5V. This substitution is valid only when the application circuit is designed to operate at 1.8V supply voltage. All other electrical and mechanical parameters remain identical, including frequency, output type, stability, temperature range, and package specifications.

Frequently Asked Questions (FAQ)

Q: Can the AX7MCF1-1500.0000C be used as a direct replacement for the AX7MBF4-1500.0000C?

A: The AX7MCF1-1500.0000C is functionally equivalent in all parameters except supply voltage. Direct substitution is possible only if your application circuit operates at 1.8V. If your circuit requires 2.5V operation, this substitute is not compatible without circuit redesign.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts use the same 8-SMD, No Lead package with dimensions of 7.00mm x 5.00mm and a maximum seated height of 1.90mm. PCB layout and footprint compatibility are maintained.

Q: Do both parts have the same frequency stability?

A: Yes. Both the AX7MBF4-1500.0000C and AX7MCF1-1500.0000C maintain ±25ppm frequency stability across the -40°C to 85°C operating temperature range.

Q: What is the moisture sensitivity level for these oscillators?

A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Are there any compliance differences between the main part and substitute?

A: No. Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory standards for electronic component procurement.
