Substitute Part Grouping Explanation

Substitution for the AX7PAF3-1500.0000C is determined by the following critical parameters:

Mandatory Matching Parameters:

• Frequency: 1.5 GHz
• Output Type: LVPECL
• Package / Case: 8-SMD, No Lead
• Physical Dimensions: 0.276" L x 0.197" W (7.00mm x 5.00mm)
• Height - Seated (Max): 0.075" (1.90mm)
• Operating Temperature Range: -40°C ~ 85°C
• Frequency Stability: ±25ppm
• Function: Enable/Disable

Allowable Variation Parameters:

• Supply Voltage: 2.5V or 3.3V (circuit design dependent)
• Current - Supply (Max): 94mA (standard for series)
• Current - Supply (Disable) (Max): 86mA (standard for series)

Substitute parts are grouped based on supply voltage compatibility. The AX7PAF3-1500.0000C operates at 3.3V. Parts with identical electrical and mechanical specifications but different supply voltages are listed as parametric equivalents for designs requiring voltage flexibility.

Parameter Comparison

Engineering Selection Recommendations

AX7PBF1-1500.0000C (MFR Recommended Substitute): This part is the manufacturer-recommended substitute for the AX7PAF3-1500.0000C. It maintains identical electrical performance, frequency stability, and mechanical compatibility. The primary difference is the reduced supply voltage of 2.5V versus 3.3V. This substitute is suitable for designs operating at 2.5V supply rails. All compliance certifications (ROHS3, MSL 1, REACH Unaffected, EAR99) are maintained.

AX7PAF1-1500.0000C (Parametric Equivalent): This part provides parametric equivalence to the main part, matching the 3.3V supply voltage requirement while maintaining all other electrical and mechanical specifications. It is suitable for direct replacement in designs requiring 3.3V operation. All compliance certifications are identical to the main part.

Frequently Asked Questions (FAQ)

Q: Can AX7PBF1-1500.0000C replace AX7PAF3-1500.0000C directly? A: Direct replacement depends on circuit design. Both parts are electrically and mechanically identical except for supply voltage. AX7PBF1-1500.0000C operates at 2.5V while AX7PAF3-1500.0000C operates at 3.3V. Substitution is valid only if your circuit power supply is 2.5V.

Q: Are all substitute parts in the same package? A: Yes. All listed parts use the 8-SMD, No Lead package with identical dimensions (0.276" L x 0.197" W, 7.00mm x 5.00mm) and maximum seated height of 0.075" (1.90mm). PCB layout and footprint compatibility is maintained across all parts.

Q: What is the difference between MFR Recommended and Parametric Equivalent? A: MFR Recommended (AX7PBF1-1500.0000C) is the manufacturer's official substitute, differing only in supply voltage (2.5V). Parametric Equivalent (AX7PAF1-1500.0000C) matches the original part's 3.3V supply voltage and all other specifications, providing an alternative source within the same voltage class.

Q: Are all parts RoHS compliant? A: Yes. All listed parts are ROHS3 Compliant with MSL 1 (Unlimited) moisture sensitivity rating and REACH Unaffected status.

Q: What frequency stability do these oscillators provide? A: All parts in this comparison provide ±25ppm frequency stability across the -40°C ~ 85°C operating temperature range.
