Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AX7DAF1-2100.0000C is determined by the following critical parameters:

• Frequency: 2.1 GHz (exact match required)
• Output Type: LVDS (exact match required)
• Package / Case: 8-SMD, No Lead (exact match required)
• Physical Dimensions: 0.276" L x 0.197" W, 0.075" max height (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)
• RoHS Status: ROHS3 Compliant (compliance requirement)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

The AX7DBF1-2100.0000C qualifies as a manufacturer-recommended substitute. While the supply voltage differs (2.5V vs. 3.3V), this represents a valid alternative within the ClearClock™ AX7 series when circuit design accommodates the lower voltage specification.

Parameter Comparison

Engineering Selection Recommendations

The AX7DBF1-2100.0000C is the manufacturer-recommended substitute for the discontinued AX7DAF1-2100.0000C. Both parts maintain ROHS3 compliance and identical mechanical compatibility. The primary design consideration is the supply voltage differential: the substitute operates at 2.5V versus the original 3.3V specification. Selection of the substitute requires confirmation that the circuit power supply and signal chain are compatible with 2.5V operation. Both parts share identical frequency stability, operating temperature range, package dimensions, and current characteristics, ensuring functional equivalence within voltage-compatible applications.

Frequently Asked Questions (FAQ)

Q: Can the AX7DBF1-2100.0000C be used as a direct replacement for the AX7DAF1-2100.0000C?

A: The AX7DBF1-2100.0000C is functionally equivalent in all parameters except supply voltage. Direct substitution is possible only if the circuit design operates at 2.5V. The identical package, frequency, output type, and stability specifications ensure mechanical and electrical compatibility within this voltage constraint.

Q: What is the primary difference between these two parts?

A: The supply voltage differs: AX7DAF1-2100.0000C requires 3.3V, while AX7DBF1-2100.0000C operates at 2.5V. All other specifications, including frequency, output type, package, and thermal characteristics, are identical.

Q: Are both parts RoHS compliant?

A: Yes, both the AX7DAF1-2100.0000C and AX7DBF1-2100.0000C are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings.

Q: Do these parts have identical physical dimensions?

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 a maximum seated height of 0.075" (1.90mm).

Q: What frequency stability do these oscillators provide?

A: Both parts provide ±25ppm frequency stability across the -40°C ~ 85°C operating temperature range.
