Key Parameters

Substitute Part Grouping Explanation

Substitution of the AX7DBF2-425.0000C is determined by the following critical parameters:

• Frequency: 425 MHz (exact match required)
• Output Type: LVDS (exact match required)
• Package Type: 8-SMD, No Lead (exact match required)
• Package Dimensions: 7.00mm x 5.00mm footprint (exact match required)
• Function: Enable/Disable capability (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Frequency Stability: ±25ppm (exact match required)
• Supply Voltage: Acceptable variation within system design constraints

The AX7DCF1-425.0000C qualifies as a manufacturer-recommended substitute. While the supply voltage differs (1.8V vs. 2.5V), this part maintains identical frequency, output type, package configuration, and all other critical electrical and mechanical parameters. The voltage difference requires system-level design verification to confirm compatibility with the target application's power supply and signal integrity requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the AX7DBF2-425.0000C and AX7DCF1-425.0000C are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. Both parts carry MSL 1 (Unlimited) moisture sensitivity ratings, indicating no special moisture handling requirements during storage or assembly.

The primary consideration for component selection is the supply voltage differential. The AX7DBF2-425.0000C operates at 2.5V, while the AX7DCF1-425.0000C operates at 1.8V. This voltage difference must be evaluated against the system's power supply architecture and signal integrity specifications. Both parts are discontinued at DiGi Electronics; inventory availability should be confirmed with authorized distributors before final procurement decisions.

Frequently Asked Questions (FAQ)

Q: Can the AX7DCF1-425.0000C directly replace the AX7DBF2-425.0000C?

A: Direct replacement requires verification that the system power supply can accommodate 1.8V operation and that signal integrity remains within specification at the lower voltage. The identical package footprint and pinout enable physical substitution, but electrical compatibility must be confirmed through design review.

Q: Are there any package or footprint differences between these parts?

A: Both parts use identical 8-SMD, No Lead packaging with 7.00mm x 5.00mm footprints and 1.90mm maximum seated height. No PCB layout modifications are required for physical substitution.

Q: What is the significance of the frequency stability rating?

A: Both parts maintain ±25ppm frequency stability across the -40°C ~ 85°C operating temperature range. This specification ensures consistent 425 MHz output performance and is identical between the main part and substitute.

Q: Do these parts require special handling during assembly?

A: Both parts carry MSL 1 (Unlimited) ratings, indicating no moisture sensitivity restrictions. Standard surface mount assembly processes apply without additional moisture control measures.

Q: Why is the main part discontinued?

A: Product discontinuation at DiGi Electronics reflects market availability changes. The AX7DCF1-425.0000C represents the manufacturer-recommended alternative within the same ClearClock™ AX7 series, maintaining functional equivalence for 425 MHz LVDS oscillator applications.
