AX7DBF2-160.0000C Equivalent & Substitute Parts

Part Overview

The AX7DBF2-160.0000C 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 production and maintenance applications requiring 160 MHz LVDS clock generation.

Substitute Part Grouping Explanation

Substitution for the AX7DBF2-160.0000C is determined by strict alignment of the following electrical and mechanical parameters:

• Frequency: 160 MHz (exact match required)
• Output: LVDS (exact match required)
• Supply Voltage: 2.5V (exact match required)
• Function: Enable/Disable (exact match required)
• Frequency Stability: ±25ppm (exact match required)
• Operating Temperature: -40°C ~ 85°C (exact match required)
• Package Footprint: 7.00mm x 5.00mm (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

The two qualified substitutes—511FBA160M000AAG (Skyworks Si511 series) and 591FB160M000DG (Skyworks Si591 series)—meet all critical electrical specifications and operate within identical environmental parameters. Both are active products with current manufacturing status, addressing the discontinuation of the original Abracon component.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are active products with current manufacturing availability, addressing the discontinuation status of the AX7DBF2-160.0000C. Selection between the two Skyworks alternatives depends on power consumption requirements:

The 511FBA160M000AAG (Si511 series) operates at 23mA maximum supply current and 18mA in disable mode, providing the lowest power consumption profile. This option is suitable for applications where power efficiency is a design priority.

The 591FB160M000DG (Si591 series) operates at 100mA maximum supply current and 75mA in disable mode. This option accommodates applications with higher current budgets or less stringent power constraints.

Both substitutes maintain identical electrical performance (160 MHz, LVDS output, 2.5V supply, ±25ppm stability) and environmental compliance (ROHS3, REACH Unaffected, EAR99 classification). Package footprints are identical at 7.00mm x 5.00mm, with seated heights of 1.80mm compared to the original 1.90mm, representing a minor dimensional improvement.

Frequently Asked Questions (FAQ)

Q: Can the 511FBA160M000AAG or 591FB160M000DG be used as direct replacements for the AX7DBF2-160.0000C?

A: Both Skyworks parts meet all critical electrical and mechanical specifications. The package footprint (7.00mm x 5.00mm) is identical, and seated heights (1.80mm) are within acceptable tolerance of the original (1.90mm). Substitution is valid from an electrical and mechanical standpoint.

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

A: The primary difference is supply current consumption. The 511FBA160M000AAG draws 23mA maximum (18mA disabled), while the 591FB160M000DG draws 100mA maximum (75mA disabled). Both deliver identical 160 MHz LVDS output at 2.5V with ±25ppm stability.

Q: Are there package differences between the original and substitutes?

A: The AX7DBF2-160.0000C uses an 8-SMD, No Lead package, while both Skyworks substitutes use a 6-SMD, No Lead package. The footprint dimensions (7.00mm x 5.00mm) and mounting type (surface mount) remain identical, ensuring PCB compatibility.

Q: Do the substitutes maintain the same compliance certifications?

A: Yes. Both 511FBA160M000AAG and 591FB160M000DG are ROHS3 compliant, REACH unaffected, and classified as EAR99. Moisture sensitivity level remains 1 (Unlimited) for all three parts.

Q: Which substitute should be selected for a new design?

A: Selection is based on power consumption requirements. For power-sensitive applications, the 511FBA160M000AAG is preferred. For applications without power constraints, either part is acceptable based on availability and cost considerations.
