Substitute Part Grouping Explanation

Substitute parts for the AX3DAF2-148.5000T3 are identified based on strict equivalence across the following critical parameters:

Frequency: 148.5 MHz (exact match required) Output Type: LVDS (exact match required) Voltage Supply: 3.3V (exact match required) Function: Enable/Disable (exact match required) Frequency Stability: ±25ppm (exact match required) Operating Temperature Range: -40°C ~ 85°C (exact match required) Current - Supply (Max): 27mA (exact match required) Current - Supply (Disable) (Max): 10µA (exact match required) Package / Case: 6-SMD, No Lead (exact match required) Physical Dimensions: 0.126" L x 0.098" W (3.20mm x 2.50mm) (exact match required) Height - Seated (Max): 0.043" (1.10mm) (exact match required) Mounting Type: Surface Mount (exact match required) Series: ClearClock™ AX3 (exact match required) Base Resonator: Crystal (exact match required) Type: XO (Standard) (exact match required)

Packaging format differences (Tape & Reel versus standard packaging) do not affect electrical or mechanical compatibility and are considered acceptable substitution criteria.

Parameter Comparison

Engineering Selection Recommendations

Both the AX3DAF2-148.5000T3 and AX3DAF1-148.5000T are Active products from Abracon LLC with identical electrical and mechanical specifications. Both devices are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The primary distinction is packaging format: the AX3DAF2-148.5000T3 uses standard packaging while the AX3DAF1-148.5000T is supplied in Tape & Reel format. Selection between these parts should be based on procurement and assembly requirements rather than electrical performance, as all functional parameters are equivalent.

Frequently Asked Questions (FAQ)

Q: Can the AX3DAF1-148.5000T replace the AX3DAF2-148.5000T3 in my application?

A: Yes. Both parts are electrically and mechanically identical. The AX3DAF1-148.5000T is supplied in Tape & Reel packaging, while the AX3DAF2-148.5000T3 uses standard packaging. If your assembly process accommodates Tape & Reel format, direct substitution is valid.

Q: Are there any differences in frequency stability between these parts?

A: No. Both parts maintain ±25ppm frequency stability across the -40°C ~ 85°C operating temperature range.

Q: Do both parts support the same supply voltage and current specifications?

A: Yes. Both operate at 3.3V with maximum supply current of 27mA and disable current of 10µA. Enable/Disable functionality is identical.

Q: What is the significance of the packaging format difference?

A: Packaging format affects procurement and assembly logistics but not electrical performance. Tape & Reel format is optimized for automated pick-and-place assembly, while standard packaging may be preferred for manual handling or smaller quantity orders.

Q: Are both parts suitable for the same PCB footprint?

A: Yes. Both parts use the 6-SMD, No Lead package with identical physical dimensions (0.126" L x 0.098" W, 3.20mm x 2.50mm) and maximum seated height of 0.043" (1.10mm).

Q: Do compliance certifications differ between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8542.39.0001.
