Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AX7DBF1-1000.0000C are identified based on strict electrical and mechanical compatibility criteria. The following parameters must remain constant or within acceptable tolerances for substitution:

• Frequency: 1 GHz (exact match required)
• Output Type: LVDS (exact match required)
• Function: Enable/Disable (exact match required)
• Frequency Stability: ±25ppm (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Package / Case: 8-SMD, No Lead (exact match required)
• Physical Dimensions: 0.276" L x 0.197" W, Height 0.075" max (exact match required)
• Current - Supply (Max): 70mA (exact match required)
• Current - Supply (Disable) (Max): 65mA (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

The primary variable parameter allowing substitution is Supply Voltage, provided all other electrical and mechanical specifications remain identical.

Parameter Comparison

Engineering Selection Recommendations

The AX7DCF1-1000.0000C serves as a direct substitute for the AX7DBF1-1000.0000C with the critical distinction of reduced supply voltage (1.8V versus 2.5V). Both parts maintain identical frequency, output characteristics, package specifications, and compliance certifications. Selection between these parts depends solely on circuit power supply architecture. The substitute part is suitable for designs operating at 1.8V rail voltage. Both parts carry ROHS3 compliance and REACH Unaffected status, ensuring regulatory alignment. Current inventory availability differs between the two parts, with the substitute offering 778 pieces in stock compared to 692 pieces for the main part.

Frequently Asked Questions (FAQ)

Q: Can the AX7DCF1-1000.0000C replace the AX7DBF1-1000.0000C in any application?

A: Substitution is valid only if the circuit power supply operates at 1.8V. The substitute part is not interchangeable in designs requiring 2.5V supply voltage. All other electrical and mechanical specifications are identical.

Q: Are the physical dimensions and package footprints identical?

A: Yes. Both parts use the 8-SMD, No Lead package with identical dimensions of 0.276" L x 0.197" W (7.00mm x 5.00mm) and maximum seated height of 0.075" (1.90mm). PCB layout and reflow profiles remain unchanged.

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

A: Yes. Both the AX7DBF1-1000.0000C and AX7DCF1-1000.0000C are ROHS3 Compliant, REACH Unaffected, and carry identical moisture sensitivity and ECCN classifications.

Q: What is the frequency stability specification for both parts?

A: Both parts maintain ±25ppm frequency stability across the -40°C ~ 85°C operating temperature range.

Q: Are there differences in current consumption between the two parts?

A: No. Both parts specify identical maximum supply current of 70mA and disable mode current of 65mA.
