Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AX7MAF2-156.2500C are identified based on strict electrical and mechanical parameter matching. The critical parameters that determine substitutability are:

• Frequency: 156.25 MHz (exact match required)
• Output Type: CML (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 Type: 8-SMD, No Lead (exact match required)
• Package Dimensions: 7.00mm x 5.00mm (exact match required)

Parts meeting all these criteria are classified as direct substitutes. Parts from the same manufacturer series with identical electrical specifications but different internal designations are classified as parametric equivalents.

Parameter Comparison

Engineering Selection Recommendations

XPC736156.250000I (Renesas Electronics Corporation) is the primary substitute for the AX7MAF2-156.2500C. This part maintains all critical electrical and mechanical parameters while offering active product status and higher inventory availability (1953 units). Both parts are ROHS3 compliant with MSL 1 rating, ensuring equivalent environmental and regulatory compliance.

AX7MAF3-156.2500C (Abracon LLC) is a parametric equivalent within the same ClearClock™ AX7 series. This part provides identical electrical specifications and package dimensions, with documented current supply ratings matching the original part. Selection between AX7MAF2-156.2500C and AX7MAF3-156.2500C depends on internal design differences within the Abracon product line; both are discontinued at DiGi Electronics.

For new designs or ongoing production requiring active product status, XPC736156.250000I is the recommended selection based on availability and active manufacturing status.

Frequently Asked Questions (FAQ)

Q: Can XPC736156.250000I be used as a direct replacement for AX7MAF2-156.2500C?

A: Yes. Both parts share identical frequency (156.25 MHz), output type (CML), supply voltage (3.3V), function (Enable/Disable), frequency stability (±25ppm), operating temperature range (-40°C ~ 85°C), and package specifications (8-SMD, No Lead, 7.00mm x 5.00mm). Electrical and mechanical compatibility is confirmed.

Q: What is the difference between AX7MAF2-156.2500C and AX7MAF3-156.2500C?

A: Both parts are from Abracon's ClearClock™ AX7 series with identical electrical and mechanical specifications. The designation difference (MAF2 vs. MAF3) indicates internal design variations within the product line. Electrical performance and package compatibility are equivalent.

Q: Are there compliance differences between the substitute parts?

A: No. All three parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. ECCN and HTSUS classifications are identical across all parts.

Q: What should be considered when selecting between available substitutes?

A: XPC736156.250000I offers active product status and higher inventory availability. AX7MAF3-156.2500C provides same-manufacturer continuity within the Abracon ClearClock™ AX7 series. Selection depends on procurement timeline, inventory requirements, and design continuity preferences.

Q: Are current supply specifications critical for substitution?

A: Current supply specifications (68mA maximum, 67mA disable) are provided for AX7MAF2-156.2500C and AX7MAF3-156.2500C. XPC736156.250000I does not specify these values in available documentation. If current supply ratings are design-critical, confirm XPC736156.250000I specifications with Renesas Electronics Corporation before final selection.
