AX7DAF3-100.0000C Equivalent & Substitute Parts

Part Overview

The AX7DAF3-100.0000C is a 100 MHz XO (Standard) LVDS Oscillator manufactured by Abracon LLC, part of the ClearClock™ AX7 series. This component provides a 3.3V enable/disable function in an 8-SMD, no-lead surface mount package. The part is currently discontinued at DiGi Electronics, making identification of equivalent alternatives necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AX7DAF3-100.0000C is determined by strict equivalence across the following critical parameters:

• Frequency: 100 MHz (exact match required)
• Output: LVDS (electrical interface specification)
• Supply Voltage: 3.3V (power requirement)
• Function: Enable/Disable (operational capability)
• Frequency Stability: ±25ppm (timing accuracy)
• Operating Temperature: -40°C ~ 85°C (environmental range)
• Package: 8-SMD, No Lead (physical and electrical interface)
• Dimensions: 7.00mm x 5.00mm (PCB footprint compatibility)
• Compliance: ROHS3 Compliant, MSL 1 (regulatory and handling requirements)

The ODEMDLVTNF-100.000000 from Taitien meets all these criteria and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The ODEMDLVTNF-100.000000 is a qualified substitute for the AX7DAF3-100.0000C based on electrical and mechanical equivalence. Both components share identical frequency, output type, supply voltage, function, frequency stability, operating temperature range, package type, and footprint dimensions. Both are ROHS3 compliant with MSL 1 rating.

The Taitien part is currently active in production, whereas the Abracon part is discontinued. Current supply availability is 990 units for the ODEMDLVTNF-100.000000 versus 1030 units for the AX7DAF3-100.0000C.

Differences in maximum supply current (90mA vs. 70mA) and disable current (110mA vs. 65mA) are within acceptable tolerance for most applications using LVDS oscillators at this frequency. The Taitien part exhibits a slightly lower maximum seated height (1.85mm vs. 1.90mm), which presents no compatibility issues for standard PCB assembly.

Frequently Asked Questions (FAQ)

Q: Can the ODEMDLVTNF-100.000000 be used as a direct replacement for the AX7DAF3-100.0000C?

A: Yes. Both components meet identical specifications for frequency, output type, supply voltage, function, frequency stability, operating temperature, package type, and footprint dimensions. Electrical and mechanical compatibility is confirmed.

Q: Are there differences in power consumption between these parts?

A: The ODEMDLVTNF-100.000000 has a higher maximum supply current (90mA vs. 70mA) and higher disable current (110mA vs. 65mA). These differences should be evaluated against your power budget, but both parts operate within standard LVDS oscillator specifications.

Q: Do both parts have the same package footprint?

A: Yes. Both use 8-SMD, no-lead packages with identical dimensions of 7.00mm x 5.00mm. The Taitien part has a maximum seated height of 1.85mm compared to 1.90mm for the Abracon part, which does not affect PCB assembly compatibility.

Q: Are both parts RoHS compliant?

A: Yes. Both the AX7DAF3-100.0000C and ODEMDLVTNF-100.000000 are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity level).

Q: Why is the Abracon part discontinued?

A: Product discontinuation decisions are made by manufacturers and distributors based on market demand and product lifecycle management. The Taitien equivalent remains in active production.
