Key Parameters

Substitute Part Grouping Explanation

Substitution for the AX7DBF2-1500.0000C is determined by the following critical parameters:

Mandatory Match Parameters:

• Frequency: 1.5 GHz
• Output Type: LVDS
• Package Type: 8-SMD, No Lead
• Operating Temperature Range: -40°C ~ 85°C
• Frequency Stability: ±25ppm
• Mounting Type: Surface Mount

Flexible Parameters (Allow Variation):

• Supply Voltage: 2.5V (primary) or 1.8V (alternative)
• Maximum Supply Current: 70mA (standard specification)
• Disable Mode Current: 65mA (standard specification)

The identified substitutes maintain identical frequency, output characteristics, package footprint, and thermal performance. Voltage supply variations are permissible when circuit design accommodates the alternative supply rail.

Parameter Comparison

Engineering Selection Recommendations

AX7DCF1-1500.0000C (MFR Recommended Substitute): This part is designated as the manufacturer-recommended alternative. It maintains full electrical and mechanical compatibility with the AX7DBF2-1500.0000C with the exception of supply voltage (1.8V vs. 2.5V). Selection of this part requires verification that the circuit design supports 1.8V operation. All compliance certifications (ROHS3, REACH Unaffected) and reliability ratings (MSL 1) are equivalent.

AX7DBF1-1500.0000C (Parametric Equivalent): This part provides direct parametric equivalence to the main part, matching the 2.5V supply voltage specification. Identical frequency, output type, package configuration, and thermal performance enable direct substitution without circuit modification. All regulatory compliance and environmental ratings are maintained.

Both substitutes are discontinued at DiGi Electronics, consistent with the main part status. Component selection should prioritize availability and lead time requirements.

Frequently Asked Questions (FAQ)

Q: Can AX7DCF1-1500.0000C replace AX7DBF2-1500.0000C directly? A: Electrical substitution is possible if the circuit design accommodates 1.8V supply voltage operation. The 1.8V supply requirement is the only parameter difference. Mechanical compatibility and package footprint are identical.

Q: What is the difference between the MFR Recommended and Parametric Equivalent substitutes? A: The MFR Recommended substitute (AX7DCF1-1500.0000C) operates at 1.8V supply voltage, while the Parametric Equivalent (AX7DBF1-1500.0000C) maintains the original 2.5V supply voltage. Both are electrically and mechanically compatible with identical frequency and output characteristics.

Q: Are all three parts pin-compatible? A: Yes. All three parts use the 8-SMD, No Lead package with identical 7.00mm x 5.00mm x 1.90mm dimensions. PCB footprint compatibility is assured.

Q: Do the substitute parts meet the same compliance requirements? A: Yes. Both substitute parts are ROHS3 Compliant, REACH Unaffected, and carry MSL 1 (Unlimited) moisture sensitivity ratings, matching the original part specifications.

Q: Which substitute should be selected for new designs? A: For new designs requiring 2.5V operation, AX7DBF1-1500.0000C provides direct parametric equivalence. For designs supporting 1.8V operation, AX7DCF1-1500.0000C is the manufacturer-recommended option. Availability and procurement lead time should guide final selection.
