AX7DBF2-270.0000C Equivalent & Substitute Parts

Part Overview

The AX7DBF2-270.0000C is a 270 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 part is discontinued at DiGi Electronics, making identification of compatible substitute components essential for ongoing system support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AX7DBF2-270.0000C is determined by the following critical parameters:

• Frequency: 270 MHz (exact match required)
• Output Type: LVDS (exact match required)
• Supply Voltage: 2.5V (exact match required)
• Function: Enable/Disable capability (exact match required)
• Frequency Stability: ±25ppm (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Base Resonator: Crystal (exact match required)
• Type: XO (Standard) (exact match required)

The identified substitute part meets all critical electrical parameters. Package configuration differences (8-SMD vs. 6-SMD) and minor variations in maximum supply current and disabled-state current are acceptable within the scope of component substitution, provided the physical footprint and height constraints are verified for the specific application.

Engineering Selection Recommendations

The 591FB270M000DG (Skyworks Solutions Inc.) is the qualified substitute for the discontinued AX7DBF2-270.0000C. Selection is based on the following engineering criteria:

Electrical Compatibility: Both parts operate identically across all critical electrical parameters—frequency, output type, supply voltage, function, frequency stability, and operating temperature range. The substitute maintains full functional equivalence.

Product Status: The Skyworks part is currently in active production status, ensuring long-term availability and supply chain continuity compared to the discontinued Abracon part.

Compliance: Both parts meet ROHS3 compliance and carry Moisture Sensitivity Level 1 (Unlimited) ratings, ensuring equivalent environmental and regulatory compliance.

Physical Considerations: While the package type differs (6-SMD vs. 8-SMD), both maintain identical footprint dimensions (7.00mm x 5.00mm) and compatible maximum heights (1.80mm vs. 1.90mm). PCB layout verification is required to confirm pad compatibility with the 6-SMD configuration.

Current Specifications: The substitute exhibits higher maximum supply current (100mA vs. 70mA) and disabled-state current (75mA vs. 65mA). Power budget analysis is necessary to confirm acceptability within the target application.

Frequently Asked Questions (FAQ)

Q: Can the 591FB270M000DG directly replace the AX7DBF2-270.0000C without design changes?

A: Electrical substitution is direct. However, the package configuration change from 8-SMD to 6-SMD requires PCB footprint verification. Pad layout and spacing must be confirmed compatible before implementation.

Q: What are the key differences between these two parts?

A: The primary differences are manufacturer (Abracon vs. Skyworks), package configuration (8-SMD vs. 6-SMD), maximum supply current (70mA vs. 100mA), and product status (discontinued vs. active). All electrical specifications remain identical.

Q: Are there any compliance or certification concerns with substitution?

A: Both parts meet ROHS3 compliance and carry identical Moisture Sensitivity Level ratings. No compliance barriers exist for substitution.

Q: How should I verify compatibility in my specific application?

A: Confirm PCB footprint compatibility with the 6-SMD package, verify that the higher maximum supply current (100mA) is acceptable within your power budget, and validate that the slightly lower maximum height (1.80mm) does not create clearance issues.

Q: Is the Skyworks part currently available?

A: Yes, the 591FB270M000DG is in active production status with reported inventory availability, providing reliable long-term supply compared to the discontinued Abracon part.
