AX3PAF4-100.0000T Equivalent & Substitute Parts

Part Overview

The AX3PAF4-100.0000T is a 100 MHz XO (Standard) LVPECL oscillator manufactured by Abracon LLC from the ClearClock™ AX3 series. This surface mount crystal oscillator operates at 3.3V with Enable/Disable functionality and is housed in a 6-SMD, No Lead package. The part is Active status and widely used in applications requiring stable 100 MHz clock signals with LVPECL output compatibility. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the allowed parameter set.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AX3PAF4-100.0000T are qualified based on strict equivalence across the following critical parameters:

• Frequency: 100 MHz (exact match required)
• Output Type: LVPECL (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 / Case: 6-SMD, No Lead (exact match required)
• Size / Dimension: 0.126" L x 0.098" W (3.20mm x 2.50mm) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

The identified substitute parts maintain full electrical and mechanical compatibility with the main part across all specified parameters. Variations in maximum supply current and seated height are within acceptable tolerances for this component category and do not affect functional substitution.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain Active product status and full ROHS3 compliance with REACH Unaffected designation. The CP3225-100.000-3.3-25-X-T-TR from Raltron Electronics and SG3225EEN 100.000000M-CDGA3 from EPSON are direct functional equivalents to the AX3PAF4-100.0000T. Selection between these parts may be based on availability, packaging format (Cut Tape & Digi-Reel® versus Tape & Reel), or supply chain requirements, as all three parts satisfy the specified electrical and mechanical parameters for this 100 MHz LVPECL oscillator application.

Frequently Asked Questions (FAQ)

Q: Can the CP3225-100.000-3.3-25-X-T-TR be used as a direct replacement for the AX3PAF4-100.0000T?

A: Yes. Both parts share identical electrical specifications (100 MHz, LVPECL, 3.3V, ±25ppm stability, Enable/Disable function) and mechanical compatibility (6-SMD No Lead package, 3.20mm x 2.50mm footprint, surface mount). The seated height difference (0.043" versus 0.047") is within acceptable tolerance for this component category.

Q: What is the difference between the SG3225EEN 100.000000M-CDGA3 and the AX3PAF4-100.0000T?

A: The SG3225EEN 100.000000M-CDGA3 from EPSON maintains all critical electrical parameters identical to the AX3PAF4-100.0000T. The maximum supply current specification is 60mA compared to 50mA, and seated height is 0.047" versus 0.043". These differences do not affect functional compatibility in applications designed for the AX3PAF4-100.0000T.

Q: Are there any package or footprint differences between these three oscillators?

A: All three parts use the 6-SMD, No Lead package with identical footprint dimensions of 0.126" L x 0.098" W (3.20mm x 2.50mm). Seated height varies slightly: AX3PAF4-100.0000T at 0.043" (1.10mm), while both substitute parts measure 0.047" (1.20mm). This variation is within standard PCB assembly tolerances.

Q: Do all three parts meet the same compliance standards?

A: Yes. All three parts are ROHS3 Compliant, REACH Unaffected, and carry Moisture Sensitivity Level 1 (Unlimited). All parts share identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications.

Q: What packaging formats are available for these substitute parts?

A: The CP3225-100.000-3.3-25-X-T-TR is supplied in Cut Tape (CT) & Digi-Reel® format. The SG3225EEN 100.000000M-CDGA3 is supplied in Tape & Reel (TR) format. Packaging selection depends on assembly line requirements and order quantities.
