Substitute Part Grouping Explanation

Substitution for the AX7DCF4-425.0000C is determined by strict equivalence across the following critical parameters:

• Frequency: 425 MHz (exact match required)
• Output Type: LVDS (electrical interface compatibility)
• Supply Voltage: 1.8V (power supply compatibility)
• Function: Enable/Disable (functional feature match)
• Frequency Stability: ±25ppm (timing accuracy specification)
• Operating Temperature Range: -40°C ~ 85°C (environmental operating limits)
• Package Type: 8-SMD, No Lead (physical and electrical interface)
• Package Dimensions: 7.00mm x 5.00mm (PCB layout compatibility)

The AX7DCF1-425.0000C meets all substitution criteria as a parametric equivalent within the ClearClock™ AX7 series.

Parameter Comparison

Engineering Selection Recommendations

Both the AX7DCF4-425.0000C and AX7DCF1-425.0000C are discontinued at DiGi Electronics. Selection between these parts should be based on current inventory availability and procurement lead times. Both parts carry identical electrical specifications, package dimensions, and compliance certifications (ROHS3, REACH Unaffected, EAR99). The AX7DCF1-425.0000C currently maintains higher inventory levels (856 Pcs) compared to the AX7DCF4-425.0000C (1100 Pcs), though both are available as new original stock. No functional or performance differentiation exists between these alternatives.

Frequently Asked Questions (FAQ)

Q: Can the AX7DCF1-425.0000C directly replace the AX7DCF4-425.0000C?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, output type (LVDS), frequency (425 MHz), supply voltage (1.8V), operating temperature range (-40°C ~ 85°C), and package dimensions (7.00mm x 5.00mm). No circuit modifications or PCB layout changes are required.

Q: Are there any differences in frequency stability between these parts?

A: No. Both parts specify ±25ppm frequency stability, ensuring equivalent timing accuracy for applications requiring this oscillator.

Q: What is the significance of the part number suffix difference (DCF4 vs. DCF1)?

A: The suffix variation indicates different internal design revisions within the ClearClock™ AX7 series. Both revisions meet identical electrical and mechanical specifications for the 425 MHz LVDS oscillator configuration.

Q: Are both parts suitable for the same PCB assembly process?

A: Yes. Both parts use identical 8-SMD, No Lead packaging with matching dimensions (7.00mm x 5.00mm x 1.90mm max height), footprint, and solder pad configuration. No assembly process modifications are necessary.

Q: Do both parts have the same compliance certifications?

A: Yes. Both parts are ROHS3 Compliant, REACH Unaffected, and classified as EAR99 for export control purposes.

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

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