AX7DBF2-320.0000C Equivalent & Substitute Parts

Part Overview

The AX7DBF2-320.0000C is a 320 MHz XO (Standard) LVDS Oscillator manufactured by Abracon LLC, part of the ClearClock™ AX7 series. This surface mount oscillator operates at 2.5V with Enable/Disable functionality and is housed in an 8-SMD, No Lead package. The product is discontinued at DiGi Electronics, making identification of equivalent substitute parts essential for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AX7DBF2-320.0000C is determined by strict alignment of the following critical parameters:

• Frequency: 320 MHz (exact match required)
• Output: LVDS (electrical interface specification)
• Supply Voltage: 2.5V (power requirement)
• Function: Enable/Disable (operational capability)
• Frequency Stability: ±25ppm (timing accuracy)
• Operating Temperature: -40°C ~ 85°C (environmental range)
• Mounting: Surface Mount (assembly compatibility)
• Physical Footprint: 7.00mm x 5.00mm (PCB layout compatibility)
• Moisture Sensitivity: MSL 1 (handling and storage requirements)
• Compliance: ROHS3 Compliant (regulatory requirement)

The substitute part 591FB320M000DG from Skyworks Solutions Inc. meets all critical electrical and mechanical parameters. Package variation (6-SMD vs. 8-SMD) and current consumption differences are secondary considerations that do not prevent functional substitution when footprint compatibility is verified.

Parameter Comparison

Engineering Selection Recommendations

The 591FB320M000DG from Skyworks Solutions Inc. is a direct functional equivalent to the discontinued AX7DBF2-320.0000C. Both parts meet identical electrical specifications for frequency, output type, supply voltage, function, and frequency stability. Both comply with ROHS3 and maintain MSL 1 moisture sensitivity ratings.

The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity. The 6-SMD package configuration differs from the original 8-SMD package; PCB layout verification is required to confirm footprint compatibility before implementation. The substitute part exhibits higher maximum current consumption (100mA vs. 70mA) and slightly lower maximum height (1.80mm vs. 1.90mm), both of which are generally favorable for thermal and space-constrained applications.

Frequently Asked Questions (FAQ)

Q: Can the 591FB320M000DG replace the AX7DBF2-320.0000C in existing designs?

A: Yes, provided that the 6-SMD package footprint is compatible with the PCB layout. All critical electrical parameters—frequency, output type, supply voltage, function, and frequency stability—are identical. Physical dimensions (7.00mm x 5.00mm) match exactly.

Q: What is the difference between the 8-SMD and 6-SMD packages?

A: The lead count differs between the two packages. The original part uses 8 leads; the substitute uses 6 leads. This affects the PCB footprint and requires layout verification. Pin assignment and electrical function remain compatible.

Q: Does the higher current consumption of the substitute part affect circuit design?

A: The substitute part draws a maximum of 100mA compared to 70mA for the original. Power supply and current delivery capacity should be evaluated to ensure adequate margin. This difference is typically accommodated in standard 2.5V supply designs.

Q: Are both parts compliant with the same regulatory standards?

A: Yes. Both the AX7DBF2-320.0000C and 591FB320M000DG are ROHS3 compliant and carry MSL 1 moisture sensitivity ratings. Both are classified under ECCN EAR99 and HTSUS 8542.39.0001.

Q: Why is the original part discontinued?

A: The AX7DBF2-320.0000C is discontinued at DiGi Electronics. The 591FB320M000DG remains in active production, providing a supported alternative for new designs and ongoing procurement.

Q: What is the maximum height difference between the two parts?

A: The original part has a maximum seated height of 1.90mm; the substitute is 1.80mm. This 0.10mm difference is generally not significant for most PCB assembly processes and may be advantageous in space-constrained applications.
