Key Parameters

Substitute Part Grouping Explanation

Substitution for the AX7DBF4-1000.0000C is determined by the following critical parameters:

Fixed Parameters (Must Match):

• Frequency: 1 GHz
• Output Type: LVDS
• Function: Enable/Disable
• Package / Case: 8-SMD, No Lead
• Physical Dimensions: 0.276" L x 0.197" W (7.00mm x 5.00mm)
• Height - Seated (Max): 0.075" (1.90mm)
• Frequency Stability: ±25ppm
• Operating Temperature Range: -40°C ~ 85°C
• Current - Supply (Max): 70mA
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Variable Parameters (Allowable Differences):

• Voltage - Supply: 1.8V or 2.5V (system design dependent)
• Current - Supply (Disable) (Max): 65mA (consistent across variants)

Two substitute parts are identified based on these criteria.

Parameter Comparison

Engineering Selection Recommendations

AX7DCF1-1000.0000C (MFR Recommended Substitute): This part is designated as the manufacturer-recommended substitute. It maintains all critical electrical and mechanical parameters identical to the main part with the exception of supply voltage (1.8V vs. 2.5V). Selection of this part requires system-level confirmation that 1.8V supply voltage is compatible with the application circuit. ROHS3 compliance and MSL rating are maintained.

AX7DBF1-1000.0000C (Parametric Equivalent): This part provides a direct parametric match to the AX7DBF4-1000.0000C, maintaining identical supply voltage (2.5V) and all other electrical specifications. This part is suitable for applications where voltage compatibility is a primary concern. ROHS3 compliance and MSL rating are maintained.

Both substitute parts are discontinued at DiGi Electronics and available in limited inventory. Selection between substitutes depends on system power supply architecture and voltage rail availability.

Frequently Asked Questions (FAQ)

Q: Can AX7DCF1-1000.0000C be used as a direct replacement for AX7DBF4-1000.0000C? A: AX7DCF1-1000.0000C is the manufacturer-recommended substitute but operates at 1.8V supply voltage instead of 2.5V. Direct substitution requires confirmation that the application circuit supports 1.8V operation and that all downstream components are compatible with this voltage level.

Q: What is the difference between the two substitute parts? A: AX7DCF1-1000.0000C operates at 1.8V supply voltage, while AX7DBF1-1000.0000C operates at 2.5V supply voltage (matching the original part). All other electrical and mechanical parameters are identical across both substitutes.

Q: Are the physical dimensions identical across all three parts? A: Yes. All three parts share identical package dimensions (0.276" L x 0.197" W / 7.00mm x 5.00mm) and maximum seated height (0.075" / 1.90mm), ensuring mechanical compatibility in PCB layouts.

Q: Do all parts meet the same compliance standards? A: Yes. All three parts are ROHS3 compliant, REACH unaffected, and carry MSL rating of 1 (Unlimited), ensuring equivalent environmental and regulatory compliance.

Q: Which substitute should be selected if supply voltage is not a constraint? A: AX7DBF1-1000.0000C provides parametric equivalence to the original part with identical 2.5V supply voltage, making it the preferred choice when voltage compatibility is not a limiting factor.
