Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AX7DBF3-425.0000C is determined by the following critical parameters:

• Frequency: 425 MHz (exact match required)
• Output Type: LVDS (exact match required)
• Package / Case: 8-SMD, No Lead (exact match required)
• Physical Dimensions: 7.00mm x 5.00mm footprint (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Frequency Stability: ±25ppm (exact match required)
• Function: Enable/Disable (exact match required)
• Series: ClearClock™ AX7 (same manufacturer series)

The AX7DCF1-425.0000C qualifies as a manufacturer-recommended substitute. While the supply voltage differs (1.8V vs. 2.5V), all other electrical and mechanical parameters remain identical. This voltage variation represents a design alternative within the same product family and does not affect physical compatibility or core oscillator performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both the AX7DBF3-425.0000C and AX7DCF1-425.0000C are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. The primary distinction is supply voltage: the main part operates at 2.5V while the substitute operates at 1.8V.

Selection between these parts depends on system power supply architecture. If the design incorporates a 2.5V rail, the AX7DBF3-425.0000C is the direct match. If the system uses 1.8V logic levels or power distribution, the AX7DCF1-425.0000C is the appropriate selection. Both parts share identical mechanical footprints, frequency specifications, and thermal operating ranges, ensuring interchangeability at the board layout level when voltage requirements are satisfied.

Frequently Asked Questions (FAQ)

Q: Can the AX7DCF1-425.0000C replace the AX7DBF3-425.0000C in an existing design?

A: Physical and mechanical compatibility is confirmed. Electrical compatibility depends on system voltage supply. If the design uses 2.5V power distribution, no substitution is required. If the system operates on 1.8V rails, the AX7DCF1-425.0000C is a direct functional replacement.

Q: Are there differences in frequency accuracy between these parts?

A: Both parts specify ±25ppm frequency stability. No difference in frequency accuracy exists between the two models.

Q: Do both parts use the same package footprint?

A: Yes. Both the AX7DBF3-425.0000C and AX7DCF1-425.0000C use the 8-SMD, No Lead package with identical dimensions of 7.00mm x 5.00mm and maximum seated height of 1.90mm. PCB layout modifications are not required for substitution.

Q: What is the operating temperature range for both oscillators?

A: Both parts operate across -40°C to 85°C. No thermal performance difference exists between the models.

Q: Are both parts RoHS compliant?

A: Yes. Both the AX7DBF3-425.0000C and AX7DCF1-425.0000C are ROHS3 compliant and REACH unaffected.
