AX7DAF2-360.0000C Equivalent & Substitute Parts

Part Overview

The AX7DAF2-360.0000C is a 360 MHz XO (Standard) LVDS Oscillator manufactured by Abracon LLC, part of the ClearClock™ AX7 series. This surface mount oscillator operates at 3.3V with Enable/Disable functionality and is housed in an 8-SMD, No Lead package. The part is currently discontinued at DiGi Electronics, making equivalent substitutes necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the AX7DAF2-360.0000C is determined by strict equivalence across the following critical parameters:

• Frequency: 360 MHz (exact match required)
• Output: LVDS (signal type compatibility)
• Supply Voltage: 3.3V (electrical compatibility)
• Function: Enable/Disable (operational feature match)
• Frequency Stability: ±25ppm (timing accuracy)
• Operating Temperature: -40°C ~ 85°C (environmental range)
• Footprint: 7.00mm x 5.00mm (PCB layout compatibility)
• RoHS3 Compliance (regulatory requirement)
• MSL 1 rating (moisture handling)

The substitute part 591BB360M000DG from Skyworks Solutions Inc. meets all these critical parameters. Package configuration differences (8-SMD vs. 6-SMD) and minor variations in maximum supply current and seated height do not prevent functional substitution when footprint compatibility is verified.

Parameter Comparison

Engineering Selection Recommendations

The 591BB360M000DG from Skyworks Solutions Inc. is the direct substitute for the discontinued AX7DAF2-360.0000C. Both parts maintain identical electrical specifications across frequency, output type, supply voltage, function, and frequency stability. The substitute part is currently in active production status with confirmed inventory availability.

Both parts carry ROHS3 compliance and MSL 1 ratings, meeting regulatory and environmental handling requirements. The 591BB360M000DG operates within the same temperature range and maintains equivalent LVDS output characteristics.

The primary design consideration is package configuration: the substitute uses a 6-SMD package versus the original 8-SMD package. Both maintain the identical 7.00mm x 5.00mm footprint, ensuring PCB layout compatibility. The substitute part's maximum supply current is 100mA compared to 70mA for the original, which is not a limiting factor in typical applications. The seated height difference (1.80mm vs. 1.90mm) is negligible for standard PCB assembly.

Frequently Asked Questions (FAQ)

Q: Can the 591BB360M000DG be used as a direct replacement for the AX7DAF2-360.0000C?

A: Yes. Both parts share identical frequency (360 MHz), output type (LVDS), supply voltage (3.3V), function (Enable/Disable), frequency stability (±25ppm), and operating temperature range (-40°C ~ 85°C). The footprint dimensions are identical at 7.00mm x 5.00mm, allowing direct PCB layout compatibility.

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

A: The package configuration differs in the number of solder pads, but both maintain the same external footprint dimensions (7.00mm x 5.00mm). The 6-SMD package of the substitute part is a more compact internal design. This does not affect PCB compatibility when footprint dimensions match.

Q: Are there any compliance or regulatory differences?

A: No. Both parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings. Both are classified under ECCN EAR99 and HTSUS 8542.39.0001.

Q: What is the impact of the higher maximum supply current in the substitute part?

A: The 591BB360M000DG specifies 100mA maximum supply current versus 70mA for the original. This specification indicates the substitute part's maximum current draw capability. In applications where the original part operated within its 70mA specification, the substitute will operate identically or with lower current draw. Higher maximum current rating does not create compatibility issues.

Q: Is the 0.10mm difference in seated height a concern?

A: No. The 0.10mm difference (1.90mm vs. 1.80mm) is within standard PCB assembly tolerances and does not affect component placement, solder joint formation, or clearance in typical applications.

Q: What is the availability status of each part?

A: The AX7DAF2-360.0000C is discontinued at DiGi Electronics. The 591BB360M000DG is in active production with confirmed inventory availability.
