Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AX7PAF4-2100.0000C are identified based on the following critical parameters that determine functional compatibility:

Mandatory Matching Parameters:

• Frequency: 2.1 GHz
• Output Type: LVPECL
• Function: Enable/Disable
• Package / Case: 8-SMD, No Lead
• Mounting Type: Surface Mount
• Operating Temperature Range: -40°C ~ 85°C
• Frequency Stability: ±25ppm

Allowable Variation Parameters:

• Voltage - Supply: 2.5V or 3.3V (circuit design dependent)
• Current - Supply (Max): 94mA (consistent across all variants)

The substitute parts listed maintain identical mechanical and electrical specifications except where voltage supply differs, which is permissible based on circuit design requirements and board-level voltage availability.

Parameter Comparison

Engineering Selection Recommendations

AX7PBF1-2100.0000C (MFR Recommended Substitute): This part is the manufacturer-recommended alternative to the AX7PAF4-2100.0000C. The primary difference is the supply voltage specification of 2.5V versus 3.3V. Selection of this part requires confirmation that the circuit design operates at 2.5V logic levels. Current inventory availability is 1097 pcs. All compliance certifications (ROHS3, MSL 1, REACH Unaffected) are maintained.

AX7PAF1-2100.0000C (Parametric Equivalent): This part provides parametric equivalence with identical supply voltage (3.3V) to the main part, eliminating voltage-level design considerations. All electrical and mechanical specifications remain unchanged. Current inventory availability is 712 pcs. All compliance certifications are maintained.

Frequently Asked Questions (FAQ)

Q: Can AX7PBF1-2100.0000C be used as a direct replacement for AX7PAF4-2100.0000C? A: Direct replacement is possible only if the circuit design operates at 2.5V logic levels. The AX7PBF1-2100.0000C is specified for 2.5V supply voltage, while the AX7PAF4-2100.0000C operates at 3.3V. Voltage compatibility must be verified at the board design level.

Q: What is the difference between the MFR Recommended and Parametric Equivalent substitutes? A: The AX7PBF1-2100.0000C (MFR Recommended) operates at 2.5V supply voltage. The AX7PAF1-2100.0000C (Parametric Equivalent) maintains the original 3.3V supply voltage specification. Both are functionally equivalent in all other parameters.

Q: Are all substitute parts pin-compatible? A: Yes. All listed parts use the identical 8-SMD, No Lead package with matching footprint dimensions (7.00mm x 5.00mm) and height (1.90mm maximum seated height).

Q: Do the substitute parts maintain the same frequency stability? A: Yes. All parts maintain ±25ppm frequency stability across the -40°C to 85°C operating temperature range.

Q: Are there any compliance or regulatory differences between the main part and substitutes? A: No. All parts are ROHS3 Compliant, carry MSL 1 (Unlimited) moisture sensitivity rating, and are REACH Unaffected. ECCN and HTSUS classifications are identical.

Q: What is the current consumption difference between Enable and Disable modes? A: Maximum supply current is 94mA in Enable mode and 86mA in Disable mode across all listed parts.
