Substitute Part Grouping Explanation

Substitution eligibility for the AX7DBF4-148.5000C is determined by strict equivalence across the following critical parameters:

• Frequency: 148.5 MHz (exact match required)
• Output Type: LVDS (exact match required)
• Supply Voltage: 2.5V (exact match required)
• Function: Enable/Disable (exact match required)
• Package Type: 8-SMD, No Lead (exact match required)
• Package Dimensions: 7.00mm x 5.00mm (exact match required)
• Frequency Stability: ±25ppm (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)

The AX7DBF3-148.5000C meets all substitution criteria as a parametric equivalent within the ClearClock™ AX7 series.

Parameter Comparison

Engineering Selection Recommendations

Both the AX7DBF4-148.5000C and AX7DBF3-148.5000C are discontinued at DiGi Electronics. Selection between these parts should be based on current inventory availability and procurement lead times. Both parts carry identical electrical specifications, mechanical dimensions, and compliance certifications (ROHS3 Compliant, REACH Unaffected). The AX7DBF3-148.5000C currently maintains higher inventory levels (715 Pcs) compared to the AX7DBF4-148.5000C (1057 Pcs), though both are available as new original stock. No technical differentiation exists between these parts for application purposes.

Frequently Asked Questions (FAQ)

Q: Can the AX7DBF3-148.5000C directly replace the AX7DBF4-148.5000C?

A: Yes. Both parts are parametric equivalents with identical frequency, output type, supply voltage, enable/disable function, package type, dimensions, and electrical characteristics. No circuit modifications are required.

Q: Are there any differences in the 8-SMD, No Lead package between these parts?

A: No. Both parts use the identical 8-SMD, No Lead package with 7.00mm x 5.00mm dimensions and 1.90mm maximum seated height. PCB footprints and assembly processes are interchangeable.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both the AX7DBF4-148.5000C and AX7DBF3-148.5000C are ROHS3 Compliant and REACH Unaffected with identical moisture sensitivity levels (MSL 1 - Unlimited).

Q: What is the significance of the frequency stability specification?

A: Both parts maintain ±25ppm frequency stability across the -40°C ~ 85°C operating temperature range. This specification determines timing accuracy in applications and is identical between the two parts.

Q: Are there supply current differences between these oscillators?

A: No. Both parts draw a maximum of 70mA during normal operation and 65mA in disable mode, making them electrically equivalent for power budget calculations.
