AX7DCF4-125.0000C Equivalent & Substitute Parts

Part Overview

The AX7DCF4-125.0000C is a 125 MHz XO (Standard) LVDS Oscillator manufactured by Abracon LLC, part of the ClearClock™ AX7 series. This surface mount oscillator operates at 1.8V with Enable/Disable functionality and is housed in an 8-SMD, No Lead package measuring 7.00mm x 5.00mm. The product is discontinued at DiGi Electronics, making identification of equivalent substitute components essential for ongoing design support and production continuity.

Substitute Part Grouping Explanation

Substitution eligibility for the AX7DCF4-125.0000C is determined by strict alignment of the following critical parameters:

• Frequency: 125 MHz (exact match required)
• Output Type: LVDS (exact match required)
• Supply Voltage: 1.8V (exact match required)
• Function: Enable/Disable (exact match required)
• Package Type: 8-SMD, No Lead (exact match required)
• Package Dimensions: 7.00mm x 5.00mm (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Frequency Stability: ±25ppm (exact match required)
• RoHS Compliance: ROHS3 Compliant (exact match required)

The ODKMDLVTNF-125.000000 from Taitien meets all substitution criteria and is classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

The ODKMDLVTNF-125.000000 (Taitien) is a qualified direct substitute for the AX7DCF4-125.0000C. The substitute part maintains active product status, ensuring ongoing availability and supply chain continuity. Both components carry identical RoHS3 compliance and REACH unaffected status, meeting regulatory requirements for current applications. The substitute exhibits a marginally lower seated height (1.85mm versus 1.90mm) and equal disable-mode current specification (70mA versus 65mA), both of which are compatible with standard PCB assembly and circuit design tolerances. Selection of the Taitien equivalent is supported by full parameter alignment and regulatory compliance parity.

Frequently Asked Questions (FAQ)

Q: Can the ODKMDLVTNF-125.000000 be used as a direct replacement for the AX7DCF4-125.0000C?

A: Yes. Both components share identical electrical specifications (125 MHz, LVDS output, 1.8V supply, Enable/Disable function, ±25ppm stability) and mechanical compatibility (8-SMD, No Lead package, 7.00mm x 5.00mm footprint). The seated height difference (1.85mm versus 1.90mm) is within standard PCB assembly tolerances.

Q: Are there compliance or certification differences between these parts?

A: No. Both components are ROHS3 compliant, REACH unaffected, and carry identical regulatory classifications (EAR99, HTSUS 8542.39.0001).

Q: What is the impact of the 5µm height difference on PCB assembly?

A: The 1.85mm seated height of the Taitien part is 5µm lower than the Abracon original. This difference is negligible for standard surface mount assembly processes and does not affect component placement, reflow soldering, or circuit performance.

Q: Does the disable-mode current specification difference affect circuit design?

A: The Taitien substitute draws 70mA in disable mode compared to 65mA for the original. This 5mA difference is within typical power management margins and does not require circuit redesign for standard applications.

Q: What is the packaging difference between these parts?

A: The Abracon part is supplied in standard packaging, while the Taitien equivalent is supplied in strip packaging. Both are compatible with automated assembly equipment; strip packaging may offer cost advantages for high-volume production.
