Key Parameters

Substitute Part Grouping Explanation

Substitution of the AX7DAF3-156.2500C is determined by strict equivalence across the following critical parameters:

• Frequency: 156.25 MHz (exact match required)
• Output Type: LVDS (exact match required)
• Supply Voltage: 3.3V (exact match required)
• Function: Enable/Disable (exact match required)
• Package Type: 8-SMD, No Lead (exact match required)
• Frequency Stability: ±25ppm (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Maximum Supply Current: 70mA (exact match required)

The AX7DAF1-156.2500 meets all these criteria and qualifies as a parametric equivalent. The primary distinction between these parts is packaging format (bulk versus strip) and product status (discontinued versus active).

Parameter Comparison

Engineering Selection Recommendations

The AX7DAF1-156.2500 is a direct parametric equivalent to the AX7DAF3-156.2500C. Both parts are manufactured by Abracon LLC within the ClearClock™ AX7 series and share identical electrical and mechanical specifications. The AX7DAF1-156.2500 is currently in active production status, whereas the AX7DAF3-156.2500C is discontinued. Both parts maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for current applications.

The distinction between these parts is limited to packaging format: the AX7DAF3-156.2500C is supplied in bulk packaging, while the AX7DAF1-156.2500 is supplied in strip packaging. This difference does not affect electrical performance, thermal characteristics, or mechanical compatibility in surface mount assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the AX7DAF1-156.2500 be used as a direct replacement for the AX7DAF3-156.2500C?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, frequency output, supply voltage, operating temperature range, and package dimensions. The only difference is packaging format (strip versus bulk).

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

A: Packaging format affects procurement and handling logistics but does not impact electrical performance or PCB assembly compatibility. Strip packaging is standard for active production parts, while bulk packaging may be used for discontinued or legacy inventory.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts carry identical RoHS3 compliance and REACH unaffected status. Moisture sensitivity level is 1 (Unlimited) for both parts.

Q: Why is the AX7DAF3-156.2500C discontinued?

A: Product discontinuation is a manufacturing decision. The AX7DAF1-156.2500 remains in active production and serves the same functional requirements.

Q: Will the AX7DAF1-156.2500 work in existing designs using the AX7DAF3-156.2500C?

A: Yes. Identical package dimensions, pin configuration, electrical specifications, and thermal characteristics ensure full compatibility in existing circuit designs and PCB layouts.
