Substitute Part Grouping Explanation

Substitute parts for the AX7DAF3-106.2500C are qualified based on the following critical parameters:

Frequency match: 106.25 MHz
Output configuration: LVDS
Supply voltage: 3.3V
Enable/Disable function capability
Frequency stability: ±25ppm
Operating temperature range: -40°C ~ 85°C
Package type: 8-SMD, No Lead
Physical dimensions: 0.276" L x 0.197" W (7.00mm x 5.00mm)
RoHS3 compliance
MSL rating: 1 (Unlimited)

Parts meeting all these parameters are considered direct substitutes. Variations in maximum supply current or disabled-state current do not disqualify substitution when all electrical and mechanical specifications align.

Engineering Selection Recommendations

AX7DAF1-106.2500C (Abracon LLC): This part is a parametric equivalent within the same ClearClock™ AX7 series from Abracon LLC. It matches all electrical and mechanical specifications of the main part. Although discontinued at DiGi Electronics, it maintains identical performance characteristics and compliance certifications (ROHS3, MSL 1). Selection of this part is appropriate when maintaining consistency within the Abracon product line is a design priority.

ODEMDLVTNF-106.250000 (Taitien): This part is a direct substitute from an alternative manufacturer. It meets all critical electrical parameters, frequency stability, operating temperature range, and package specifications. The maximum supply current (90mA vs. 70mA) and disabled-state current (110mA vs. 65mA) are higher but do not prevent substitution when power budget constraints are not limiting factors. This part is currently active in inventory, making it the preferred choice for new procurement when supply continuity is required. RoHS3 compliance and MSL 1 rating ensure regulatory and handling compatibility.

Frequently Asked Questions (FAQ)

Q: Can the ODEMDLVTNF-106.250000 be used as a direct replacement for the AX7DAF3-106.2500C?

A: Yes. Both parts operate at 106.25 MHz with LVDS output, 3.3V supply, Enable/Disable function, and identical frequency stability (±25ppm). Package dimensions and thermal specifications are compatible. The higher maximum supply current of the Taitien part does not prevent substitution in applications where power consumption is within acceptable limits.

Q: What is the difference between the AX7DAF3-106.2500C and AX7DAF1-106.2500C?

A: Both are Abracon ClearClock™ AX7 series oscillators with identical electrical and mechanical specifications. The primary difference is product status; both are discontinued at DiGi Electronics. They are parametric equivalents suitable for direct substitution.

Q: Are there any height clearance concerns when substituting the Taitien part?

A: The Taitien ODEMDLVTNF-106.250000 has a maximum seated height of 0.073" (1.85mm), which is 0.002" (0.05mm) lower than the Abracon parts at 0.075" (1.90mm). This difference presents no clearance issues in standard PCB designs and may provide marginal benefit in space-constrained layouts.

Q: Do all substitute parts meet the same compliance requirements?

A: Yes. All three parts are ROHS3 compliant with MSL rating 1 (Unlimited). The Abracon AX7DAF3-106.2500C and AX7DAF1-106.2500C also carry REACH Unaffected status. All parts share the same ECCN (EAR99) and HTSUS (8542.39.0001) classifications.

Q: Which substitute part should be selected for new designs?

A: The ODEMDLVTNF-106.250000 from Taitien is recommended for new designs due to its active product status and current inventory availability. The AX7DAF1-106.2500C may be selected if maintaining the Abracon product line is a design requirement, subject to availability verification.
