Substitute Part Grouping Explanation

Substitution eligibility for the AX7DCF4-2100.0000C is determined by strict equivalence across the following critical parameters:

• Frequency: 2.1 GHz (exact match required)
• Output Configuration: LVDS (exact match required)
• Supply Voltage: 1.8V (exact match required)
• Enable/Disable Function: Present (exact match required)
• Package Type: 8-SMD, No Lead (exact match required)
• Package Dimensions: 7.00mm x 5.00mm (exact match required)
• Frequency Stability: ±25ppm (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)

The identified substitute part AX7DCF1-2100.0000C meets all critical parameters and is therefore classified as a parametric equivalent.

Frequently Asked Questions (FAQ)

Q: Can the AX7DCF1-2100.0000C be used as a direct replacement for the AX7DCF4-2100.0000C?

A: Yes. Both parts are parametric equivalents with identical frequency, output type, supply voltage, package configuration, and all electrical specifications. No circuit modifications are required.

Q: Are there any differences in the package footprint between these parts?

A: No. Both parts use the same 8-SMD, No Lead package with identical dimensions of 7.00mm x 5.00mm and maximum seated height of 1.90mm. PCB layout and assembly processes remain unchanged.

Q: Do both parts meet the same compliance and regulatory requirements?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and classified as EAR99. Moisture sensitivity level is MSL 1 (Unlimited) for both.

Q: What is the difference between the part numbers AX7DCF4 and AX7DCF1?

A: The part numbers differ in the fourth and fifth characters (DCF4 versus DCF1), but all provided electrical and mechanical parameters are identical. This variation does not affect functional equivalence for the specified application.

Q: Are there any current or power consumption differences?

A: No. Maximum supply current is 70mA and maximum disable current is 65mA for both parts.
