Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AX7DBF1-1500.0000C is determined by strict alignment of the following critical parameters:

• Frequency: 1.5 GHz (exact match required)
• Output Type: LVDS (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)
• Function: Enable/Disable (exact match required)
• Frequency Stability: ±25ppm (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Compliance: ROHS3 Compliant, MSL 1 (exact match required)

The AX7DCF1-1500.0000C qualifies as a manufacturer-recommended substitute. While the supply voltage differs (1.8V vs. 2.5V), this represents a design variation within the same product family and series, with all other electrical and mechanical parameters maintained at specification.

Parameter Comparison

Engineering Selection Recommendations

The AX7DCF1-1500.0000C is designated as the manufacturer-recommended substitute for the discontinued AX7DBF1-1500.0000C. Both components maintain identical ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment. The substitute part is currently available with 788 pcs in stock, compared to the main part's discontinued status.

The primary design consideration is the supply voltage differential: the substitute operates at 1.8V versus the main part's 2.5V. This variation is inherent to the product family design and does not affect frequency, output type, stability, temperature range, or package specifications. Circuit design must accommodate the lower supply voltage requirement of the substitute part.

Frequently Asked Questions (FAQ)

Q: Can the AX7DCF1-1500.0000C directly replace the AX7DBF1-1500.0000C in existing designs?

A: Direct replacement requires circuit-level evaluation of the 1.8V supply voltage requirement. The substitute part maintains all other electrical and mechanical specifications. Power supply compatibility must be verified before implementation.

Q: Are the physical dimensions identical between the main part and substitute?

A: Yes. Both components use the 8-SMD, No Lead package with 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 assembly processes remain unchanged.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the AX7DBF1-1500.0000C and AX7DCF1-1500.0000C are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating and REACH unaffected status.

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

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

Q: Is the substitute part currently available?

A: Yes. The AX7DCF1-1500.0000C has 788 pcs in stock as new original inventory, whereas the main part is discontinued at DiGi Electronics.
