AX7DAF2-2100.0000C Equivalent & Substitute Parts

Part Overview

The AX7DAF2-2100.0000C is a 2.1 GHz XO (Standard) LVDS Oscillator manufactured by Abracon LLC as part of the ClearClock™ AX7 series. This surface mount oscillator operates at 3.3V with Enable/Disable functionality, housed in an 8-SMD, No Lead package measuring 7.00mm x 5.00mm. The part is discontinued at DiGi Electronics, making identification of equivalent substitutes necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AX7DAF2-2100.0000C is determined by the following critical parameters:

• Frequency: Must be 2.1 GHz (exact match required)
• Output Type: Must be LVDS (signal integrity requirement)
• Package Type: Must be 8-SMD, No Lead with identical footprint dimensions (7.00mm x 5.00mm)
• Function: Must support Enable/Disable capability
• Frequency Stability: Must meet or exceed ±25ppm specification
• Operating Temperature Range: Must cover -40°C ~ 85°C minimum
• RoHS Compliance: Must maintain ROHS3 Compliant status

The supply voltage parameter (3.3V for the main part) is not a strict substitution requirement if the substitute operates at a different voltage, provided the circuit design accommodates the voltage difference and all other electrical and mechanical parameters align.

Parameter Comparison

Engineering Selection Recommendations

The AX7DBF1-2100.0000C qualifies as a direct substitute for the AX7DAF2-2100.0000C based on matching frequency, output type, package footprint, function, frequency stability, operating temperature range, and regulatory compliance status. Both parts maintain ROHS3 Compliant and REACH Unaffected certifications.

The primary design consideration is the supply voltage difference: the substitute operates at 2.5V versus the main part's 3.3V. Circuit-level voltage regulation and signal integrity verification are required before implementation in applications originally specified for 3.3V operation.

Both parts are discontinued at DiGi Electronics. Current inventory availability should be verified with authorized distributors before final procurement decisions.

Frequently Asked Questions (FAQ)

Q: Can the AX7DBF1-2100.0000C replace the AX7DAF2-2100.0000C in existing designs?

A: Substitution is possible if the circuit design can accommodate 2.5V supply voltage operation. The identical frequency, LVDS output, package footprint, and functional specifications ensure mechanical and electrical compatibility at the component level. Voltage regulation and signal integrity must be validated for the specific application.

Q: Are the package dimensions identical between these parts?

A: Yes. Both parts use the 8-SMD, No Lead package with dimensions of 7.00mm x 5.00mm and maximum seated height of 1.90mm. PCB footprints are interchangeable.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the AX7DAF2-2100.0000C and AX7DBF1-2100.0000C are ROHS3 Compliant, REACH Unaffected, and classified under ECCN EAR99 with HTSUS code 8542.39.0001.

Q: What is the frequency stability specification for both parts?

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

Q: Are there differences in current consumption between these oscillators?

A: No. Both parts specify maximum supply current of 70mA during normal operation and 65mA during disable mode.
