Substitute Part Grouping Explanation

Substitution for the AX7DAF1-148.5000C 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: 3.3V (exact match required)
• Function: Enable/Disable (exact match required)
• Frequency Stability: ±25ppm (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Package / Case: 8-SMD, No Lead (exact match required)
• Physical Dimensions: 0.276" L x 0.197" W (7.00mm x 5.00mm) (exact match required)
• Height - Seated (Max): 0.075" (1.90mm) (exact match required)
• Current - Supply (Max): 70mA (exact match required)
• Current - Supply (Disable) (Max): 65mA (exact match required)
• Mounting Type: Surface Mount (exact match required)

The substitute part AX7DAF1-148.5000 meets all these criteria and is classified as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

The AX7DAF1-148.5000 is a direct parametric equivalent to the AX7DAF1-148.5000C. Both parts are manufactured by Abracon LLC within the ClearClock™ AX7 series and share identical electrical and mechanical specifications. The primary distinction is product status: the AX7DAF1-148.5000C is discontinued at DiGi Electronics, while the AX7DAF1-148.5000 maintains active status with higher inventory availability (1081 Pcs vs. 840 Pcs).

Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements. The substitute part is suitable for direct replacement in applications requiring 148.5 MHz LVDS oscillation at 3.3V with Enable/Disable control across the -40°C to 85°C operating range.

Frequently Asked Questions (FAQ)

Q: Can AX7DAF1-148.5000 replace AX7DAF1-148.5000C in existing designs?

A: Yes. Both parts are parametrically identical across all electrical and mechanical specifications, including frequency, output type, supply voltage, package dimensions, and current ratings. Direct substitution is supported.

Q: What is the difference between the two part numbers?

A: The primary difference is product status and packaging designation. The AX7DAF1-148.5000C is discontinued at DiGi Electronics, while AX7DAF1-148.5000 is active with Strip packaging. All functional and electrical parameters are identical.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain identical RoHS3 compliance, REACH unaffected status, and Moisture Sensitivity Level (MSL) 1 rating.

Q: Does the packaging difference (Strip vs. unspecified) affect compatibility?

A: No. Packaging designation refers to the distribution format and does not affect component functionality, electrical performance, or physical dimensions. Both parts use the same 8-SMD, No Lead package with identical dimensions and height specifications.

Q: What inventory considerations should be evaluated?

A: The AX7DAF1-148.5000 offers higher current inventory (1081 Pcs vs. 840 Pcs) and active product status, providing better long-term availability for procurement planning.
