AX7DBF3-160.0000C Equivalent & Substitute Parts

Part Overview

The AX7DBF3-160.0000C is a 160 MHz XO (Standard) LVDS Oscillator manufactured by Abracon LLC, part of the ClearClock™ AX7 series. This component operates at 2.5V with Enable/Disable functionality in an 8-SMD, No Lead surface mount package. The part is discontinued at DiGi Electronics, making equivalent substitutes necessary for ongoing system support and new designs requiring this frequency and output specification.

Substitute Part Grouping Explanation

Substitution for the AX7DBF3-160.0000C is determined by the following critical parameters that must remain constant:

Frequency: 160 MHz
Output Type: LVDS
Supply Voltage: 2.5V
Function: Enable/Disable
Frequency Stability: ±25ppm
Operating Temperature Range: -40°C ~ 85°C
Mounting Type: Surface Mount
Physical Footprint: 7.00mm x 5.00mm
Moisture Sensitivity Level: 1 (Unlimited)
RoHS Compliance: ROHS3 Compliant

The two qualified substitutes (511FBA160M000AAG and 591FB160M000DG) from Skyworks Solutions Inc. meet all critical electrical and environmental specifications. Both are active products with current inventory availability. Package variations (6-SMD vs. 8-SMD) and current consumption differences are noted but do not prevent functional substitution when PCB layout accommodates the footprint.

Engineering Selection Recommendations

Both substitute parts are active products with current manufacturing status and full inventory availability, addressing the discontinuation of the original AX7DBF3-160.0000C.

The 511FBA160M000AAG offers the lowest current consumption at 23mA (active) and 18mA (disabled), making it suitable for power-constrained applications. This part operates within the same electrical and environmental specifications as the original.

The 591FB160M000DG provides higher current capacity at 100mA (active) and 75mA (disabled), accommodating applications with greater power delivery requirements while maintaining identical frequency, output type, voltage, and stability specifications.

Both substitutes feature reduced package complexity (6-SMD vs. 8-SMD) and lower seated height (1.80mm vs. 1.90mm), providing potential PCB layout advantages. All three parts maintain identical footprint dimensions (7.00mm x 5.00mm), MSL rating, and RoHS compliance status.

Frequently Asked Questions (FAQ)

Q: Can the 511FBA160M000AAG or 591FB160M000DG be used as direct replacements for the AX7DBF3-160.0000C?

A: Both parts meet the critical electrical specifications: 160 MHz frequency, LVDS output, 2.5V supply, Enable/Disable function, ±25ppm stability, and -40°C to 85°C operating range. PCB layout must accommodate the 6-SMD package configuration and 1.80mm seated height. Pinout compatibility must be verified against your specific application schematic.

Q: What is the difference between the two substitute parts?

A: The primary difference is current consumption. The 511FBA160M000AAG draws 23mA maximum (active) and 18mA (disabled), while the 591FB160M000DG draws 100mA maximum (active) and 75mA (disabled). Select based on your power budget requirements.

Q: Are there package compatibility concerns?

A: The original part uses an 8-SMD package; both substitutes use 6-SMD packages. While the footprint dimensions remain identical (7.00mm x 5.00mm), the pad layout differs. PCB redesign or rework may be required. The substitutes are slightly lower in height (1.80mm vs. 1.90mm), which is generally favorable for clearance.

Q: Do the substitutes maintain the same compliance certifications?

A: Yes. Both substitutes are ROHS3 compliant and have MSL rating of 1 (Unlimited), matching the original part's compliance status.

Q: What is the inventory status of these parts?

A: The 511FBA160M000AAG has 924 pieces in stock, and the 591FB160M000DG has 936 pieces in stock, both available as new original components in strip packaging.
