• Function: Enable/Disable capability (exact match required)
• Frequency Stability: ±20ppm (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Package Type: 8-SMD, No Lead (exact match required)
• Package Dimensions: 5.00mm x 3.20mm x 1.50mm maximum (exact match required)
• Supply Current Ratings: 80mA maximum, 70mA disable (exact match required)
• Compliance: ROHS3 Compliant, MSL 1 (exact match required)

Parameter Comparison

Engineering Selection Recommendations

The AX5DBF1-400.0000C serves as a parametric equivalent to the AX5DBF4-400.0000C. Both parts are manufactured by Abracon LLC within the ClearClock™ AX5 series and maintain identical electrical and mechanical specifications. The substitution is valid based on:

• Identical frequency, output type, and voltage specifications
• Matching frequency stability and temperature operating range
• Equivalent current consumption characteristics
• Identical package configuration and dimensions
• Equivalent compliance certifications (ROHS3, MSL 1)

Both parts are discontinued at DiGi Electronics. Component selection should be based on current inventory availability and lead time requirements from authorized distributors.

Frequently Asked Questions (FAQ)

Q: Can the AX5DBF1-400.0000C replace the AX5DBF4-400.0000C in existing designs?

A: Yes. The AX5DBF1-400.0000C is a parametric equivalent with identical electrical specifications, output characteristics, supply voltage, frequency stability, and package configuration. No design 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 (5.00mm x 3.20mm x 1.50mm maximum height). Pin assignments and functional behavior are equivalent.

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

A: The suffix variation indicates different internal design revisions or manufacturing batches within the Abracon ClearClock™ AX5 series. Both variants meet the same parametric specifications and are functionally interchangeable.

Q: Are both parts RoHS compliant?

A: Yes. Both the AX5DBF4-400.0000C and AX5DBF1-400.0000C are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: What should I consider when sourcing these discontinued parts?

A: Verify current inventory availability through authorized distributors. Both parts are discontinued at DiGi Electronics but may be available through secondary market channels. Confirm part authenticity and storage conditions, particularly given the MSL 1 rating which allows unlimited shelf life without special moisture control.
