Key Parameters

Substitute Part Grouping Explanation

Substitution of the AX7DCF4-1000.0000C is determined by strict equivalence across the following critical parameters:

• Frequency: 1 GHz (exact match required)
• Output Type: LVDS (electrical interface specification)
• Supply Voltage: 1.8V (power requirement)
• Function: Enable/Disable (control capability)
• Frequency Stability: ±25ppm (timing accuracy)
• Operating Temperature Range: -40°C ~ 85°C (environmental specification)
• Package Type: 8-SMD, No Lead (mechanical and thermal interface)
• Package Dimensions: 7.00mm x 5.00mm (PCB layout compatibility)
• Maximum Seated Height: 1.90mm (clearance requirement)

The AX7DCF1-1000.0000C meets all these criteria and qualifies as a parametric equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

Both parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. The AX7DCF1-1000.0000C is a direct parametric equivalent with identical electrical and mechanical specifications. Both parts are discontinued at DiGi Electronics; however, the substitute part currently has higher inventory availability (778 Pcs vs. 720 Pcs). Selection between these parts should be based on procurement availability and supply chain requirements, as they are functionally and physically interchangeable.

Frequently Asked Questions (FAQ)

Q: Can the AX7DCF1-1000.0000C replace the AX7DCF4-1000.0000C in existing designs?

A: Yes. Both parts are parametric equivalents with identical frequency, output type, supply voltage, function, frequency stability, operating temperature range, and package specifications. No design modifications are required.

Q: Are there any differences in the electrical performance between these parts?

A: No. Both parts specify identical maximum supply current (70mA), frequency stability (±25ppm), and disable mode current (65mA).

Q: Do these parts have the same physical footprint?

A: Yes. Both parts use the 8-SMD, No Lead package with identical dimensions (7.00mm x 5.00mm) and maximum seated height (1.90mm). PCB layouts are directly compatible.

Q: What is the significance of the part number suffix difference (DCF4 vs. DCF1)?

A: The suffix variation indicates different internal configurations within the ClearClock™ AX7 series. However, the provided specifications are identical across all critical parameters that determine substitutability.

Q: Are both parts subject to the same compliance requirements?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity level (MSL 1 - Unlimited) and regulatory classifications (ECCN: EAR99, HTSUS: 8542.39.0001).
