Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AX7DBF3-1500.0000C are identified based on the following critical parameters that determine functional compatibility:

Mandatory Matching Parameters:

• Frequency: 1.5 GHz
• Output Type: LVDS
• Function: Enable/Disable
• Package / Case: 8-SMD, No Lead
• Physical Dimensions: 7.00mm x 5.00mm
• Operating Temperature Range: -40°C ~ 85°C
• Frequency Stability: ±25ppm

Allowable Variation Parameters:

• Voltage - Supply: Substitutes may operate at different supply voltages (1.8V or 2.5V) provided the application circuit supports voltage adjustment
• Current - Supply (Max): Substitutes with equivalent or lower maximum supply current are acceptable
• Current - Supply (Disable) (Max): Substitutes with equivalent or lower disable current are acceptable

The substitute parts identified below maintain all mandatory parameters while offering alternative supply voltage options to accommodate different system requirements.

Parameter Comparison

Engineering Selection Recommendations

AX7DCF1-1500.0000C (MFR Recommended Substitute): This part is designated as the manufacturer-recommended substitute. It maintains identical electrical performance and physical compatibility with the main part across all critical parameters. The primary difference is the reduced supply voltage requirement (1.8V versus 2.5V). Selection of this part is appropriate for applications where lower supply voltage operation is supported by the system design. All compliance certifications (ROHS3, REACH Unaffected) and reliability ratings (MSL 1) are equivalent.

AX7DBF1-1500.0000C (Parametric Equivalent): This part provides parametric equivalence to the main part, maintaining identical supply voltage (2.5V) and all other electrical and mechanical specifications. This substitute is suitable for direct replacement in existing designs without circuit modification. Compliance and reliability ratings are identical to the main part.

Both substitute parts are discontinued at DiGi Electronics, consistent with the main part status. Selection between substitutes should be based on system supply voltage requirements and available inventory.

Frequently Asked Questions (FAQ)

Q: Can AX7DCF1-1500.0000C be used as a direct replacement for AX7DBF3-1500.0000C?

A: AX7DCF1-1500.0000C is functionally compatible with AX7DBF3-1500.0000C for all electrical and mechanical parameters. The supply voltage difference (1.8V versus 2.5V) requires that the application circuit support 1.8V operation. If the system is designed for 2.5V supply only, circuit modification is necessary.

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

A: AX7DCF1-1500.0000C (MFR Recommended) operates at 1.8V supply voltage and is the manufacturer's designated alternative. AX7DBF1-1500.0000C (Parametric Equivalent) maintains the original 2.5V supply voltage specification. Both parts are electrically and mechanically equivalent across all other parameters.

Q: Are all three parts pin-compatible?

A: Yes. All three parts use the 8-SMD, No Lead package with identical physical dimensions (7.00mm x 5.00mm, 1.90mm height). PCB footprints are interchangeable.

Q: Do the substitute parts meet the same compliance requirements?

A: Yes. All three parts are ROHS3 Compliant, REACH Unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. Compliance certifications are identical.

Q: What is the frequency stability specification for these oscillators?

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

Q: Are there inventory considerations for part selection?

A: Current inventory levels are: AX7DBF3-1500.0000C (845 Pcs), AX7DCF1-1500.0000C (788 Pcs), and AX7DBF1-1500.0000C (718 Pcs). All parts are listed as new original stock. Availability should be confirmed with the supplier for production quantities.
