Substitute Part Grouping Explanation

Substitution eligibility for the AX7MBF2-915.0000C is determined by the following critical parameters:

  • Frequency: 915 MHz (exact match required)
  • Output Configuration: CML (exact match required)
  • Function: Enable/Disable capability (exact match required)
  • Package / Case: 8-SMD, No Lead (exact match required)
  • Physical Dimensions: 7.00mm x 5.00mm footprint, 1.90mm max height (exact match required)
  • Operating Temperature Range: -40°C ~ 85°C (exact match required)
  • Frequency Stability: ±25ppm (exact match required)
  • RoHS Compliance: ROHS3 Compliant (exact match required)

The AX7MCF2-915.0000C qualifies as a manufacturer-recommended substitute. While the supply voltage differs (1.8V versus 2.5V), this represents a valid alternative within the ClearClock™ AX7 series when circuit design accommodates the lower voltage specification. All other critical parameters remain identical.

Engineering Selection Recommendations

The AX7MCF2-915.0000C is the manufacturer-recommended substitute for the discontinued AX7MBF2-915.0000C. Both parts maintain identical frequency, output configuration, package specifications, and compliance certifications. The primary design consideration is supply voltage: the substitute operates at 1.8V compared to the original 2.5V specification.

Selection of the substitute part requires verification that the circuit power supply architecture can accommodate 1.8V operation. When 1.8V supply voltage is available or can be implemented, the AX7MCF2-915.0000C provides full functional equivalence with identical electrical performance characteristics, thermal operating range, and regulatory compliance status.

Both parts carry ROHS3 compliance and REACH Unaffected status, supporting equivalent environmental and regulatory requirements for industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Can the AX7MCF2-915.0000C directly replace the AX7MBF2-915.0000C without circuit modification?

A: Direct replacement is possible only if the circuit power supply can operate at 1.8V. The substitute part requires 1.8V supply voltage versus the original 2.5V specification. Circuit redesign or power supply adjustment may be necessary.

Q: Are the physical dimensions and mounting 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 footprints and assembly processes remain unchanged.

Q: Do both parts meet the same frequency stability and temperature operating requirements?

A: Yes. Both parts specify ±25ppm frequency stability and operate across the -40°C ~ 85°C temperature range. Frequency performance and thermal characteristics are equivalent.

Q: What is the significance of the supply voltage difference?

A: The AX7MCF2-915.0000C operates at lower supply voltage (1.8V), which may reduce power consumption in applications where 1.8V rails are available. However, this requires circuit compatibility verification. The original AX7MBF2-915.0000C at 2.5V may be necessary if only higher voltage supplies are present.

Q: Are regulatory and compliance certifications identical?

A: Yes. Both parts carry ROHS3 compliance and REACH Unaffected status. Environmental and regulatory requirements are equivalent for both parts.

Q: What is the current consumption difference between the parts?

A: Both parts specify identical maximum supply current of 68mA and disable current of 67mA. Power consumption characteristics are equivalent.
