Substitute Part Grouping Explanation

Substitute parts for the AX7DCF3-156.2500C are identified based on strict electrical and mechanical parameter matching. The critical parameters that define substitutability are:

• Frequency: 156.25 MHz (exact match required)
• Output Type: LVDS (exact match required)
• Supply Voltage: 1.8V (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)

Parts meeting all these criteria are classified as parametric equivalents and may be used as direct substitutes in applications where the AX7DCF3-156.2500C is specified.

Parameter Comparison

Engineering Selection Recommendations

The AX7DCF1-156.2500C is a parametric equivalent substitute for the AX7DCF3-156.2500C. Both parts are manufactured by Abracon LLC within the ClearClock™ AX7 series and share identical electrical specifications, frequency stability, operating temperature range, and package configuration.

Both parts maintain ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements for electronic component procurement. The MSL 1 rating indicates unlimited shelf life under standard storage conditions.

Selection between these parts should be based on component availability and procurement lead times, as all functional and compliance parameters are equivalent.
