Substitute Part Grouping Explanation

Substitution for the AX7DAF4-915.0000C is determined by strict equivalence across the following critical parameters:

• Frequency: 915 MHz (exact match required)
• Output Configuration: LVDS (exact match required)
• Supply Voltage: 3.3V (exact match required)
• Function: Enable/Disable capability (exact match required)
• Frequency Stability: ±25ppm (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Package Type: 8-SMD, No Lead (exact match required)
• Physical Dimensions: 7.00mm x 5.00mm footprint (exact match required)

The AX7DAF1-915.0000 meets all substitution criteria as a parametric equivalent from the same manufacturer and series, with identical electrical and mechanical specifications. The primary difference is packaging format (Strip vs. standard packaging) and product status (Active vs. Discontinued).

Parameter Comparison

Engineering Selection Recommendations

The AX7DAF1-915.0000 is a direct parametric equivalent suitable for replacing the discontinued AX7DAF4-915.0000C. Both parts maintain identical electrical performance, frequency stability, and thermal operating range. The substitute part carries Active product status, ensuring continued availability and manufacturer support.

Both parts satisfy ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial and commercial applications. The packaging format difference (Strip vs. standard) does not affect electrical or mechanical compatibility; this distinction relates only to procurement and handling procedures.

Selection of the AX7DAF1-915.0000 as a replacement eliminates supply chain risk associated with the discontinued main part while maintaining full functional equivalence in 915 MHz LVDS oscillator applications requiring 3.3V operation and Enable/Disable control.

Frequently Asked Questions (FAQ)

Q: Can the AX7DAF1-915.0000 be used as a direct replacement for the AX7DAF4-915.0000C?

A: Yes. Both parts are parametric equivalents with identical frequency, output type, supply voltage, function, frequency stability, operating temperature range, and package specifications. The parts are electrically and mechanically interchangeable.

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

A: The primary difference is packaging format. The AX7DAF4-915.0000C uses standard packaging, while the AX7DAF1-915.0000 is supplied in Strip format. Additionally, the AX7DAF1-915.0000 maintains Active product status, whereas the AX7DAF4-915.0000C is discontinued.

Q: Does the Strip packaging format affect PCB assembly compatibility?

A: No. Strip packaging is a procurement and handling format that does not affect the component's electrical characteristics, physical footprint, or soldering process. The 8-SMD, No Lead package and 7.00mm x 5.00mm dimensions remain identical.

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

A: No. Both parts are ROHS3 compliant and REACH unaffected. Regulatory compliance is equivalent across both part numbers.

Q: What is the significance of the Active product status for the substitute part?

A: Active product status indicates that the AX7DAF1-915.0000 is currently manufactured and supported by Abracon LLC, ensuring long-term availability and supply chain stability compared to the discontinued AX7DAF4-915.0000C.
