AX7DBF4-100.0000C Equivalent & Substitute Parts

Part Overview

The AX7DBF4-100.0000C is a 100 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 product is discontinued at DiGi Electronics, making equivalent substitute parts necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AX7DBF4-100.0000C are qualified based on the following critical parameters:

• Frequency Match: 100 MHz operation
• Output Configuration: LVDS output
• Supply Voltage: 2.5V operation
• Enable/Disable Function: Required control capability
• Frequency Stability: ±25ppm tolerance
• Operating Temperature: -40°C ~ 85°C range
• Package Compatibility: 8-SMD, No Lead form factor with matching footprint dimensions (7.00mm x 5.00mm)
• Regulatory Compliance: ROHS3 Compliant, MSL 1

The ODJMDLVTNF-100.000000 from Taitien meets all these criteria and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The ODJMDLVTNF-100.000000 from Taitien is a qualified substitute for the discontinued AX7DBF4-100.0000C. Both parts share identical electrical specifications for frequency, output type, supply voltage, function, frequency stability, and operating temperature range. Both are ROHS3 compliant with MSL 1 rating.

The Taitien part carries an active product status, ensuring ongoing availability and supply chain continuity. The maximum supply current specification is slightly higher (80mA vs. 70mA), which does not present a constraint for applications designed for the original part. The seated height difference (1.85mm vs. 1.90mm) is within acceptable PCB assembly tolerances for 8-SMD packages.

Frequently Asked Questions (FAQ)

Q: Can the ODJMDLVTNF-100.000000 be used as a direct replacement for the AX7DBF4-100.0000C?

A: Yes. Both parts operate at 100 MHz with LVDS output, 2.5V supply, enable/disable function, and identical frequency stability. Package dimensions and footprints are matched at 7.00mm x 5.00mm. Both are ROHS3 compliant with MSL 1 rating.

Q: What is the difference in current consumption between these parts?

A: The Taitien ODJMDLVTNF-100.000000 specifies a maximum supply current of 80mA compared to 70mA for the Abracon AX7DBF4-100.0000C. This 10mA difference does not affect compatibility for applications designed around the original part's specifications.

Q: Are there any height differences that affect PCB assembly?

A: The seated height differs by 0.05mm (1.85mm vs. 1.90mm). This variation is within standard PCB assembly tolerances for surface mount components and does not require design modifications.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both parts are ROHS3 compliant, carry MSL 1 (Unlimited) moisture sensitivity rating, and share the same ECCN (EAR99) and HTSUS (8542.39.0001) classifications.

Q: Why is the Abracon part discontinued?

A: Product discontinuation is determined by the manufacturer and distributor. The Taitien ODJMDLVTNF-100.000000 remains in active production and provides equivalent functionality for new designs and ongoing support.
