Substitute Part Grouping Explanation

Substitute parts for the AX7DBF2-1000.0000C are classified based on the following substitution criteria:

MFR Recommended Substitute: AX7DCF1-1000.0000C differs in supply voltage (1.8V vs. 2.5V). This part is suitable only when the design can accommodate a lower supply voltage specification.

Parametric Equivalent: AX7DBF1-1000.0000C maintains identical electrical and mechanical specifications to the main part, including 2.5V supply voltage, making it a direct functional replacement within the same series.

The critical parameters determining substitutability are:

• Frequency: 1 GHz (all parts match)
• Output Type: LVDS (all parts match)
• Package / Case: 8-SMD, No Lead (all parts match)
• Operating Temperature Range: -40°C ~ 85°C (all parts match)
• Frequency Stability: ±25ppm (all parts match)
• Supply Voltage: 2.5V (main part and parametric equivalent) vs. 1.8V (MFR recommended)

Parameter Comparison

Engineering Selection Recommendations

AX7DBF1-1000.0000C (Parametric Equivalent): This part is the primary substitute for the AX7DBF2-1000.0000C. Both parts maintain identical electrical specifications, mechanical dimensions, and compliance certifications. Selection of this part requires no design modifications and provides direct functional replacement.

AX7DCF1-1000.0000C (MFR Recommended): This part is suitable only when the design power supply can accommodate 1.8V operation. The lower supply voltage specification represents a design constraint that must be evaluated against system requirements. Both parts maintain ROHS3 compliance and identical package specifications.

All substitute parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings, consistent with the original part's environmental specifications.

Frequently Asked Questions (FAQ)

Q: Can AX7DBF1-1000.0000C be used as a direct replacement for AX7DBF2-1000.0000C?

A: Yes. AX7DBF1-1000.0000C is a parametric equivalent with identical electrical and mechanical specifications, including 2.5V supply voltage, 1 GHz frequency, LVDS output, and 8-SMD, No Lead package. No design modifications are required.

Q: What is the key difference between AX7DCF1-1000.0000C and the main part?

A: The primary difference is supply voltage. AX7DCF1-1000.0000C operates at 1.8V, while AX7DBF2-1000.0000C operates at 2.5V. All other electrical and mechanical parameters remain identical. Use AX7DCF1-1000.0000C only if your design power supply supports 1.8V operation.

Q: Are all substitute parts in the same package?

A: Yes. All parts listed 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 modifications are not required.

Q: Do the substitute parts maintain the same compliance certifications?

A: Yes. All substitute parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity ratings, matching the original part's environmental and regulatory specifications.

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

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