Substitute Part Grouping Explanation

Substitute parts for the AX7DBF3-2100.0000C are identified based on the following critical parameters that determine functional compatibility:

Mandatory Matching Parameters:

• Frequency: 2.1 GHz
• Output Type: LVDS
• Package / Case: 8-SMD, No Lead
• Frequency Stability: ±25ppm
• Operating Temperature Range: -40°C ~ 85°C
• Mounting Type: Surface Mount

Allowable Variation Parameters:

• Supply Voltage: 2.5V (main part) to 1.8V (substitute acceptable with circuit design consideration)
• Current specifications: Within rated maximums

The substitute parts identified maintain identical mechanical packaging, frequency output, and thermal operating range. Voltage supply differences are permissible when the application circuit supports dual-voltage operation or when system redesign accommodates the alternative voltage specification.

Parameter Comparison

Engineering Selection Recommendations

AX7DCF1-2100.0000C (MFR Recommended Substitute): This part is designated as the manufacturer-recommended substitute. It maintains all critical electrical and mechanical specifications with the exception of supply voltage (1.8V vs. 2.5V). Selection of this part requires circuit-level evaluation to confirm compatibility with 1.8V operation. This part carries ROHS3 compliance and MSL 1 rating identical to the main part.

AX7DBF1-2100.0000C (Parametric Equivalent): This part provides direct parametric equivalence to the AX7DBF3-2100.0000C, maintaining identical supply voltage (2.5V), frequency, output type, and all mechanical specifications. This represents the closest functional match and requires no circuit redesign. ROHS3 compliance and MSL 1 rating are maintained.

Both substitute parts are discontinued at DiGi Electronics, consistent with the main part status. Selection between the two substitutes depends on whether the application circuit can accommodate 1.8V operation (AX7DCF1-2100.0000C) or requires 2.5V supply (AX7DBF1-2100.0000C).

Frequently Asked Questions (FAQ)

Q: Can AX7DCF1-2100.0000C replace AX7DBF3-2100.0000C directly without circuit modification?

A: Direct replacement requires circuit evaluation. The primary difference is supply voltage: AX7DCF1-2100.0000C operates at 1.8V while AX7DBF3-2100.0000C operates at 2.5V. If the application circuit supports dual-voltage operation or can be redesigned for 1.8V, direct replacement is feasible. Otherwise, AX7DBF1-2100.0000C is the appropriate choice.

Q: What is the difference between the MFR Recommended and Parametric Equivalent substitutes?

A: AX7DCF1-2100.0000C (MFR Recommended) differs in supply voltage specification (1.8V). AX7DBF1-2100.0000C (Parametric Equivalent) maintains identical supply voltage (2.5V) to the original part. The parametric equivalent requires no circuit redesign.

Q: Are all three parts mechanically interchangeable?

A: Yes. All three parts share identical package specifications (8-SMD, No Lead), dimensions (7.00mm x 5.00mm), and height (1.90mm maximum). Mechanical interchangeability is confirmed.

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

A: Yes. Both substitute parts carry ROHS3 compliance and MSL 1 (Unlimited) rating, matching the original AX7DBF3-2100.0000C specifications.

Q: What is the inventory status of the substitute parts?

A: AX7DCF1-2100.0000C has 839 pcs in stock. AX7DBF1-2100.0000C has 786 pcs in stock. Both parts are discontinued at DiGi Electronics, consistent with the main part status.
