Substitute Part Grouping Explanation

Substitute parts for the AX3DAF3-148.5000T are identified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution criteria are:

Electrical Parameters (Must Match Exactly):

• Frequency: 148.5 MHz
• Output Type: LVDS
• Supply Voltage: 3.3V
• Frequency Stability: ±25ppm
• Current - Supply (Max): 27mA
• Current - Supply (Disable) (Max): 10µA
• Function: Enable/Disable

Mechanical Parameters (Must Match Exactly):

• Package / Case: 6-SMD, No Lead
• Size / Dimension: 0.126" L x 0.098" W (3.20mm x 2.50mm)
• Height - Seated (Max): 0.043" (1.10mm)
• Mounting Type: Surface Mount

Compliance & Status (Must Match Exactly):

• Series: ClearClock™ AX3
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• Product Status: Active

The AX3DAF1-148.5000T qualifies as a parametric equivalent substitute, differing only in packaging format (Tape & Reel vs. standard packaging), which does not affect electrical performance or mechanical compatibility in the application circuit.

Parameter Comparison

Engineering Selection Recommendations

Both the AX3DAF3-148.5000T and AX3DAF1-148.5000T are Active status products from Abracon LLC with identical electrical performance and mechanical specifications. Selection between these parts is determined by packaging and supply chain requirements:

AX3DAF3-148.5000T is appropriate for applications where standard packaging is specified or preferred for inventory management.

AX3DAF1-148.5000T is appropriate for high-volume production environments where Tape & Reel (TR) packaging provides automated assembly advantages and is currently available with higher inventory levels (1911 Pcs vs. 935 Pcs).

Both parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard PCB assembly processes and storage conditions. No additional testing or verification is required when substituting between these parts, as all electrical and mechanical parameters are identical.

Frequently Asked Questions (FAQ)

Q: Can AX3DAF1-148.5000T be used as a direct replacement for AX3DAF3-148.5000T?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (Tape & Reel vs. standard). This does not affect circuit performance, PCB layout, or assembly compatibility.

Q: What is the difference between the two part numbers?

A: The difference is limited to packaging. AX3DAF3-148.5000T uses standard packaging, while AX3DAF1-148.5000T uses Tape & Reel (TR) packaging. All electrical specifications, frequency output, voltage supply, current consumption, and physical dimensions are identical.

Q: Are there any compliance or certification differences?

A: No. Both parts carry identical certifications: ROHS3 Compliant, REACH Unaffected, MSL 1 (Unlimited), and ECCN EAR99 classification.

Q: Which part should I select for my design?

A: Selection depends on your assembly process. For manual or small-batch assembly, either part is suitable. For automated high-volume production, AX3DAF1-148.5000T (Tape & Reel) is typically preferred due to assembly line compatibility and current higher inventory availability.

Q: Do I need to modify my PCB layout or schematic when switching between these parts?

A: No. Both parts use identical 6-SMD, No Lead packages with the same footprint dimensions (3.20mm x 2.50mm) and height (1.10mm maximum). PCB layout and schematic remain unchanged.

Q: What is the operating temperature range for both parts?

A: Both parts operate across -40°C to 85°C, with frequency stability maintained at ±25ppm across this range.
