Key Parameters

Substitute Part Grouping Explanation

Substitution of the AX7DAF2-156.2500C is determined by strict equivalence across the following critical parameters:

• Frequency: 156.25 MHz (exact match required)
• Output Type: LVDS (electrical interface specification)
• Supply Voltage: 3.3V (power requirement)
• Function: Enable/Disable capability (operational feature)
• Frequency Stability: ±25ppm (timing accuracy specification)
• Operating Temperature Range: -40°C ~ 85°C (environmental specification)
• Package Type: 8-SMD, No Lead (physical and electrical interface)
• Compliance: ROHS3 Compliant, Moisture Sensitivity Level 1

The AX7DAF1-156.2500 meets all these criteria and is classified as a parametric equivalent. The primary distinction is product status and packaging format, not electrical or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

The AX7DAF1-156.2500 is a direct parametric equivalent to the AX7DAF2-156.2500C. Both parts are manufactured by Abracon LLC within the ClearClock™ AX7 series and share identical electrical specifications, frequency output, and physical package dimensions.

The AX7DAF1-156.2500 is currently in active production status, whereas the AX7DAF2-156.2500C is discontinued. For new designs or system replenishment, the AX7DAF1-156.2500 is the appropriate selection. Both parts maintain ROHS3 compliance and identical moisture sensitivity ratings, ensuring regulatory and environmental consistency.

The only operational difference is packaging format: the AX7DAF2-156.2500C is supplied in bulk packaging, while the AX7DAF1-156.2500 is supplied in strip packaging. This distinction does not affect electrical performance 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 AX7DAF2-156.2500C?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, frequency output (156.25 MHz), LVDS output type, 3.3V supply voltage, Enable/Disable function, frequency stability (±25ppm), operating temperature range (-40°C ~ 85°C), and 8-SMD, No Lead package dimensions. The parts are functionally interchangeable in circuit design and PCB layout.

Q: What is the difference between the AX7DAF2-156.2500C and AX7DAF1-156.2500?

A: The primary differences are product status and packaging format. The AX7DAF2-156.2500C is discontinued and supplied in bulk packaging. The AX7DAF1-156.2500 is in active production and supplied in strip packaging. All electrical and mechanical parameters are identical.

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

A: No. Both parts carry identical ROHS3 compliance status, Moisture Sensitivity Level 1 (Unlimited), REACH Unaffected status, and ECCN/HTSUS classifications. Regulatory and environmental compliance is equivalent.

Q: Does the packaging format (bulk vs. strip) affect assembly compatibility?

A: No. Packaging format affects only procurement and handling logistics. Both bulk and strip packaging contain the same component with identical electrical and mechanical specifications. Surface mount assembly processes are unaffected by packaging format.

Q: What supply current specifications apply to both parts?

A: Both parts operate at a maximum supply current of 70mA during normal operation and 65mA during disable mode. Current consumption is identical between the two parts.
