Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AX7DBF1-2100.0000C is determined by the following critical parameters:

• Frequency: 2.1 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)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Frequency Stability: ±25ppm (exact match required)
• Series: ClearClock™ AX7 (same manufacturer series)
• RoHS & Compliance: ROHS3 Compliant, MSL 1 (exact match required)

The AX7DCF1-2100.0000C qualifies as a substitute based on matching all critical mechanical, electrical, and environmental parameters. The primary difference is the supply voltage specification (1.8V vs. 2.5V), which represents a distinct variant within the same product family designed for different power supply architectures.

Parameter Comparison

Engineering Selection Recommendations

The AX7DCF1-2100.0000C serves as the manufacturer-recommended substitute for the discontinued AX7DBF1-2100.0000C. Both components maintain identical mechanical compatibility, frequency performance, and environmental ratings. Selection between these variants depends on system power supply architecture:

• AX7DBF1-2100.0000C (2.5V): Select when system power rails provide 2.5V supply voltage
• AX7DCF1-2100.0000C (1.8V): Select when system power rails provide 1.8V supply voltage

Both variants carry ROHS3 compliance and MSL 1 rating, ensuring equivalent regulatory and handling requirements. Current consumption specifications remain constant across both variants (70mA max, 65mA max in disable mode).

Frequently Asked Questions (FAQ)

Q: Can the AX7DCF1-2100.0000C replace the AX7DBF1-2100.0000C in existing designs?

A: Direct substitution requires verification that your system power supply can accommodate the 1.8V requirement. The AX7DCF1-2100.0000C is electrically and mechanically compatible with identical frequency, output type, package, and thermal specifications. If your design uses 2.5V rails exclusively, a voltage regulator or power supply modification is necessary.

Q: Are there any package or footprint differences between these parts?

A: No. Both components use identical 8-SMD, No Lead packaging 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 footprints are interchangeable.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the AX7DBF1-2100.0000C and AX7DCF1-2100.0000C are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited moisture sensitivity level) ratings. Regulatory and environmental handling requirements are identical.

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

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

Q: Is the current consumption the same for both supply voltage variants?

A: Yes. Maximum supply current is 70mA for both parts, with 65mA maximum in disable mode, regardless of the 1.8V or 2.5V supply voltage difference.
