Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AX7DAF4-100.0000C are qualified based on the following critical parameters that determine functional and mechanical compatibility:

Electrical Parameters:

• Frequency: 100 MHz (exact match required)
• Output: LVDS (exact match required)
• Supply Voltage: 3.3V (exact match required)
• Function: Enable/Disable (exact match required)
• Frequency Stability: ±25ppm (exact match required)
• Operating Temperature: -40°C ~ 85°C (exact match required)

Mechanical Parameters:

• Package Type: 8-SMD, No Lead (exact match required)
• Package Dimensions: 7.00mm x 5.00mm (exact match required)
• Mounting Type: Surface Mount (exact match required)

Compliance Parameters:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Substitute parts meeting all electrical, mechanical, and compliance criteria are considered direct functional equivalents suitable for PCB-level replacement without design modification.

Parameter Comparison

Engineering Selection Recommendations

AX7DAF3-100.0000C (Abracon LLC): This part is a parametric equivalent within the same ClearClock™ AX7 series from Abracon LLC. It matches all critical electrical and mechanical specifications. Both the main part and this equivalent are discontinued at DiGi Electronics, indicating similar market availability constraints. Selection of this part maintains consistency within the Abracon product line and supply chain.

ODEMDLVTNF-100.000000 (Taitien): This part is a direct functional equivalent from an alternative manufacturer. It meets all required electrical parameters (frequency, output type, supply voltage, function, stability, and temperature range) and mechanical specifications (package type, dimensions, and mounting). The part is currently active in inventory. Supply current specifications differ (90mA maximum vs. 70mA for the main part, and 110mA disable current vs. 65mA), but these remain within acceptable operational margins for 3.3V LVDS oscillator applications. This part is suitable for designs where alternative sourcing is required.

Both substitute parts carry ROHS3 compliance and MSL 1 ratings, matching the environmental and regulatory requirements of the original part.

Frequently Asked Questions (FAQ)

Q: Can ODEMDLVTNF-100.000000 be used as a direct replacement for AX7DAF4-100.0000C?

A: Yes. Both parts share identical electrical specifications (100 MHz, LVDS output, 3.3V supply, enable/disable function, ±25ppm stability, -40°C to 85°C operating range) and mechanical specifications (8-SMD No Lead package, 7.00mm x 5.00mm dimensions). The higher supply current ratings of the Taitien part do not prevent direct PCB-level substitution.

Q: What is the difference between AX7DAF4-100.0000C and AX7DAF3-100.0000C?

A: Both parts are from Abracon's ClearClock™ AX7 series and are parametrically equivalent. They share identical electrical and mechanical specifications. The primary difference is product status: both are currently discontinued at DiGi Electronics.

Q: Are there any height clearance concerns when substituting ODEMDLVTNF-100.000000?

A: The Taitien part has a maximum seated height of 1.85mm compared to 1.90mm for the Abracon parts. This 0.05mm difference is negligible for standard PCB assembly and does not present clearance concerns in typical applications.

Q: Do all substitute parts meet the same compliance requirements?

A: Yes. All parts listed are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings, matching the environmental and regulatory compliance of the original AX7DAF4-100.0000C.

Q: Which substitute part should be selected for new designs?

A: Selection depends on supply chain requirements. ODEMDLVTNF-100.000000 is currently active in inventory and represents the most readily available option. AX7DAF3-100.0000C maintains manufacturer consistency within the Abracon product line but shares discontinued status with the original part.
