AX7DCF4-100.0000C Equivalent & Substitute Parts

Part Overview

The AX7DCF4-100.0000C is a 100 MHz XO (Standard) LVDS Oscillator manufactured by Abracon LLC, part of the ClearClock™ AX7 series. This component operates at 1.8V with Enable/Disable functionality in an 8-SMD, No Lead surface mount package. The part is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives for ongoing production and maintenance applications.

Substitute Part Grouping Explanation

Substitution eligibility for the AX7DCF4-100.0000C is determined by strict alignment of the following critical parameters:

• Frequency: 100 MHz (exact match required)
• Output Configuration: LVDS (exact match required)
• Supply Voltage: 1.8V (exact match required)
• Enable/Disable Function: Present (required for functional equivalence)
• Package Type: 8-SMD, No Lead (exact match required)
• Package Dimensions: 7.00mm x 5.00mm (exact match required)
• Frequency Stability: ±25ppm (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• RoHS Compliance: ROHS3 Compliant (required for regulatory equivalence)

The ODKMDLVTNF-100.000000 from Taitien meets all substitution criteria and qualifies as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

The ODKMDLVTNF-100.000000 (Taitien, OD-M series) is a qualified substitute for the discontinued AX7DCF4-100.0000C. Both components are ROHS3 compliant and carry identical electrical and mechanical specifications across all critical parameters. The Taitien part maintains active product status, ensuring continued availability for production applications.

The seated height differential (1.85mm vs. 1.90mm) is within typical PCB assembly tolerances and does not impact functional compatibility. The disable mode current specification (70mA vs. 65mA) represents a marginal increase within acceptable operational limits for 1.8V LVDS oscillator applications.

Frequently Asked Questions (FAQ)

Q: Can the ODKMDLVTNF-100.000000 be used as a direct replacement for the AX7DCF4-100.0000C?

A: Yes. Both components share identical frequency (100 MHz), output type (LVDS), supply voltage (1.8V), package configuration (8-SMD, No Lead), and dimensional specifications (7.00mm x 5.00mm). All electrical parameters, including frequency stability (±25ppm) and operating temperature range (-40°C ~ 85°C), are equivalent.

Q: Are there any physical compatibility concerns with the Taitien substitute?

A: No. The package type, footprint, and pin configuration are identical. The seated height of the Taitien part (1.85mm) is 0.05mm lower than the original, which is within standard PCB assembly tolerances and does not affect board-level compatibility.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the AX7DCF4-100.0000C and ODKMDLVTNF-100.000000 are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity ratings. Both carry identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications.

Q: What is the difference in disable mode current consumption?

A: The Taitien part draws 70mA in disable mode compared to 65mA for the Abracon part. This 5mA difference is negligible for typical 1.8V oscillator applications and does not impact system-level power budgeting.

Q: Is the Taitien part currently available?

A: Yes. The ODKMDLVTNF-100.000000 maintains active product status with documented inventory availability, unlike the discontinued Abracon part.
