Key Parameters

Substitute Part Grouping Explanation

Substitution for the AX7MCF2-491.5200C is determined by strict equivalence across the following critical parameters:

• Frequency: 491.52 MHz (exact match required)
• Output Type: CML (LVPECL-compatible signaling)
• Supply Voltage: 1.8V (single supply operation)
• Function: Enable/Disable capability
• Frequency Stability: ±25ppm tolerance
• Operating Temperature: -40°C ~ 85°C range
• Package: 8-SMD, No Lead form factor
• Compliance: ROHS3 and REACH status

The AX7MCF1-491.5200C meets all these criteria and is classified as a parametric equivalent. Both parts share identical electrical specifications, mechanical dimensions, and regulatory compliance, differing only in internal revision designation.

Parameter Comparison

Frequently Asked Questions (FAQ)

Q: Can the AX7MCF1-491.5200C be used as a direct replacement for the AX7MCF2-491.5200C?

A: Yes. Both parts are parametric equivalents with identical frequency, output type, supply voltage, temperature range, package dimensions, and compliance certifications. No circuit modifications are required.

Q: Are there any differences in electrical performance between these two part numbers?

A: No. Both parts specify 491.52 MHz frequency, ±25ppm stability, 1.8V supply, 68mA maximum current, and CML output. Performance characteristics are identical.

Q: Do both parts use the same package footprint?

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

Q: What is the significance of the different part number designations (MCF2 vs. MCF1)?

A: The designation difference reflects internal revision levels within Abracon's ClearClock™ AX7 series. Both revisions meet identical electrical and mechanical specifications for this frequency and output configuration.

Q: Are moisture sensitivity and handling requirements the same?

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

Q: Can I mix AX7MCF1 and AX7MCF2 parts in the same production batch?

A: Yes. Since both parts are parametric equivalents with identical specifications, they can be used interchangeably within the same design and manufacturing process.
