Key Parameters

Substitute Part Grouping Explanation

Substitution of the AX7DCF2-491.5200C is determined by strict equivalence across the following critical parameters:

• Frequency: 491.52 MHz (exact match required)
• Output Type: LVDS (signal integrity dependent)
• Supply Voltage: 1.8V (circuit compatibility required)
• Function: Enable/Disable (operational feature match)
• Frequency Stability: ±25ppm (timing tolerance match)
• Operating Temperature Range: -40°C ~ 85°C (environmental specification match)
• Package / Case: 8-SMD, No Lead (PCB layout compatibility)
• Physical Dimensions: 0.276" L x 0.197" W, Height 0.075" (mechanical fit requirement)

The AX7DCF1-491.5200C meets all these criteria and qualifies as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the AX7DCF2-491.5200C and AX7DCF1-491.5200C are discontinued at DiGi Electronics. Selection between these parts should be based on current inventory availability and procurement lead times. Both parts carry identical ROHS3 compliance, REACH unaffected status, and EAR99 export classification, ensuring regulatory equivalence for applications requiring environmental and trade compliance documentation.

The AX7DCF1-491.5200C currently maintains higher inventory availability (672 Pcs) compared to the main part (904 Pcs), making it a viable procurement alternative for designs requiring immediate component sourcing.

Frequently Asked Questions (FAQ)

Q: Can the AX7DCF1-491.5200C be used as a direct replacement for the AX7DCF2-491.5200C?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, frequency output, supply voltage, enable/disable function, and physical package dimensions. No circuit modifications are required.

Q: Are there any differences in the pin configuration or signal integrity between these parts?

A: No. Both parts use the same 8-SMD, No Lead package with identical physical dimensions and LVDS output characteristics. Pin configuration and signal integrity are equivalent.

Q: What is the significance of the part number suffix difference (AX7DCF2 vs. AX7DCF1)?

A: The suffix variation indicates different manufacturing revisions within the Abracon ClearClock™ AX7 series. Both revisions meet the same electrical and mechanical specifications for this frequency and output type.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both parts operate across the identical temperature range of -40°C to 85°C with the same frequency stability specification of ±25ppm.

Q: What compliance certifications apply to both parts?

A: Both parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export purposes. Moisture sensitivity level is 1 (Unlimited) for both.
