Substitute Part Grouping Explanation

Substitution eligibility for the AX3PBF4-100.0000 is determined by strict equivalence across the following critical parameters:

• Frequency: 100 MHz (exact match required)
• Output Type: LVPECL (exact match required)
• Supply Voltage: 2.5V (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: 6-SMD, No Lead (exact match required)
• Physical Dimensions: 3.20mm x 2.50mm x 1.10mm (exact match required)
• Mounting Type: Surface Mount (exact match required)

The identified substitute part AX3PBF1-100.0000 meets all electrical and mechanical specifications. The primary difference is packaging configuration: AX3PBF4-100.0000 is supplied in standard packaging, while AX3PBF1-100.0000 is supplied in strip packaging. Both parts are manufactured by Abracon LLC within the same ClearClock™ AX3 series and maintain identical functional and performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both AX3PBF4-100.0000 and AX3PBF1-100.0000 are active production parts with ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on packaging requirements:

• AX3PBF4-100.0000: Use when standard packaging is required for inventory management or assembly processes.
• AX3PBF1-100.0000: Use when strip packaging is preferred for automated pick-and-place assembly operations or when strip format aligns with production workflow.

Both parts carry identical electrical performance, thermal characteristics, and regulatory compliance. The choice between them does not impact circuit functionality or reliability.

Frequently Asked Questions (FAQ)

Q: Can AX3PBF1-100.0000 be used as a direct replacement for AX3PBF4-100.0000?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (standard versus strip). If your assembly process accommodates strip packaging, AX3PBF1-100.0000 is a direct functional substitute.

Q: Does packaging format affect circuit performance?

A: No. Packaging format is a logistics and assembly consideration only. Once mounted on the PCB, both parts deliver identical electrical performance, frequency stability, and operating characteristics.

Q: Are there any compliance differences between these parts?

A: No. Both parts maintain identical RoHS3 compliance, REACH status, and regulatory certifications. MSL rating is 1 (Unlimited) for both.

Q: What is the primary reason to choose one part over the other?

A: The selection criterion is packaging preference. Choose AX3PBF4-100.0000 for standard packaging workflows or AX3PBF1-100.0000 for strip packaging workflows. Inventory availability may also influence selection.

Q: Are the physical dimensions identical?

A: Yes. Both parts are 3.20mm x 2.50mm with a maximum seated height of 1.10mm. They are pin-compatible and footprint-compatible for PCB assembly.
