Key Parameters

Substitute Part Grouping Explanation

Substitution of the AX7DAF2-2000.0000C is determined by the following critical parameters:

• Frequency: 2 GHz (exact match required)
• Output Type: LVDS (exact match required)
• Package / Case: 8-SMD, No Lead (exact match required)
• Function: Enable/Disable (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Frequency Stability: ±25ppm (exact match required)
• Mounting Type: Surface Mount (exact match required)

The primary variable parameter allowing substitution is Voltage - Supply. The AX7DAF2-2000.0000C operates at 3.3V. Equivalent parts within the ClearClock™ AX7 series may operate at alternative supply voltages (such as 2.5V) while maintaining all other electrical and mechanical specifications. This voltage difference is permissible only when the target application circuit supports the lower supply voltage without functional degradation.

Parameter Comparison

Engineering Selection Recommendations

Both the AX7DAF2-2000.0000C and AX7DBF1-2000.0000C are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. Both parts carry MSL Level 1 (Unlimited) moisture sensitivity classification, indicating no special moisture handling requirements during storage or assembly.

The AX7DBF1-2000.0000C operates at 2.5V supply voltage compared to the 3.3V requirement of the AX7DAF2-2000.0000C. Selection of the substitute part is contingent upon circuit design compatibility with 2.5V operation. If the target application requires 3.3V supply voltage, the substitute part is not suitable. If the application circuit supports 2.5V operation and all other electrical and mechanical parameters align with design requirements, the AX7DBF1-2000.0000C is a valid equivalent.

Frequently Asked Questions (FAQ)

Q: Can the AX7DBF1-2000.0000C replace the AX7DAF2-2000.0000C in any application?

A: The AX7DBF1-2000.0000C is electrically and mechanically compatible only if the application circuit is designed to operate at 2.5V supply voltage. The substitute part cannot be used in circuits requiring 3.3V supply voltage.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts are housed in 8-SMD, No Lead packages with identical dimensions of 0.276" L x 0.197" W (7.00mm x 5.00mm) and maximum seated height of 0.075" (1.90mm). PCB layout and footprint are interchangeable.

Q: Do both parts have the same frequency stability specification?

A: Yes. Both the AX7DAF2-2000.0000C and AX7DBF1-2000.0000C maintain ±25ppm frequency stability across the -40°C ~ 85°C operating temperature range.

Q: What is the primary difference between these oscillators?

A: The sole electrical difference is supply voltage. The AX7DAF2-2000.0000C requires 3.3V, while the AX7DBF1-2000.0000C operates at 2.5V. All other specifications including frequency, output type, function, stability, and package are identical.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical MSL Level 1 (Unlimited) moisture sensitivity ratings.
