Substitute Part Grouping Explanation

Substitution for the AX7DBF4-622.0800C is determined by strict equivalence across the following critical parameters:

• Frequency: 622.08 MHz (exact match required)
• Output Configuration: LVDS (no alternative output types acceptable)
• Supply Voltage: 2.5V (no voltage derating permitted)
• Enable/Disable Function: Required
• Package Type: 8-SMD, No Lead (mechanical and electrical compatibility)
• Operating Temperature Range: -40°C ~ 85°C (minimum requirement)
• Frequency Stability: ±25ppm (maximum tolerance)

The AX7DBF1-622.0800C meets all substitution criteria as a parametric equivalent within the ClearClock™ AX7 series.

Parameter Comparison

Engineering Selection Recommendations

The AX7DBF1-622.0800C is a direct parametric equivalent to the AX7DBF4-622.0800C. Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The substitute part maintains identical electrical specifications, frequency accuracy, and thermal operating range. Both parts are classified as discontinued at DiGi Electronics, indicating limited availability in the market. Selection between these parts should be based on current inventory status and procurement lead times from authorized distributors.

Frequently Asked Questions (FAQ)

Q: Can the AX7DBF1-622.0800C be used as a direct replacement for the AX7DBF4-622.0800C?

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

Q: Are there any differences in the pin configuration between these parts?

A: No. Both parts use the same 8-SMD, No Lead package with identical dimensions (7.00mm x 5.00mm x 1.90mm maximum height). Pin assignments and electrical characteristics are equivalent.

Q: What is the significance of the part number suffix difference (DBF4 vs. DBF1)?

A: The suffix indicates internal design variants within the ClearClock™ AX7 series. Both variants meet the same electrical and mechanical specifications for this frequency and output configuration.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the AX7DBF4-622.0800C and AX7DBF1-622.0800C are ROHS3 compliant and REACH unaffected.

Q: What is the moisture sensitivity level for these oscillators?

A: Both parts are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Can these parts be used in applications requiring extended temperature ranges beyond -40°C to 85°C?

A: No. The specified operating temperature range is -40°C to 85°C. Applications requiring extended temperature operation require alternative part selection.
