AX3PAF4-100.0000T3 Equivalent & Substitute Parts

Part Overview

The AX3PAF4-100.0000T3 is a 100 MHz XO (Standard) LVPECL oscillator manufactured by Abracon LLC, part of 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 currently active in production with 967 units in stock. Equivalent and substitute parts are identified for applications requiring component alternatives due to supply constraints, design flexibility, or inventory optimization.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AX3PAF4-100.0000T3 are qualified based on 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 Type: 6-SMD, No Lead (exact match required)
• Package Dimensions: 3.20mm x 2.50mm (exact match required)
• RoHS Compliance: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

All identified substitute parts meet these criteria and are therefore electrically and mechanically interchangeable with the main part.

Parameter Comparison

Engineering Selection Recommendations

All three parts—AX3PAF4-100.0000T3 (Abracon), CP3225-100.000-3.3-25-X-T-TR (Raltron), and SG3225EEN 100.000000M-CDGA3 (EPSON)—are active production components with ROHS3 compliance and REACH Unaffected status. They are electrically and mechanically interchangeable for 100 MHz LVPECL oscillator applications requiring 3.3V supply with enable/disable functionality.

The primary difference is maximum supply current: the Abracon and Raltron parts specify 50mA maximum, while the EPSON part specifies 60mA maximum. This difference does not affect substitution eligibility but should be considered in power budget calculations for applications operating near maximum current limits.

Height variation exists between the main part (1.10mm seated height) and both substitute parts (1.20mm seated height). This 0.10mm difference must be evaluated against PCB layout constraints and clearance requirements in the target application.

Frequently Asked Questions (FAQ)

Q: Can CP3225-100.000-3.3-25-X-T-TR be used as a direct replacement for AX3PAF4-100.0000T3?

A: Yes. Both parts meet identical electrical and mechanical specifications for 100 MHz LVPECL oscillator operation at 3.3V with enable/disable functionality. The 6-SMD, No Lead package dimensions (3.20mm x 2.50mm) are identical. The seated height difference (1.10mm vs. 1.20mm) must be verified against PCB clearance requirements.

Q: Can SG3225EEN 100.000000M-CDGA3 be used as a direct replacement for AX3PAF4-100.0000T3?

A: Yes. Both parts meet identical electrical and mechanical specifications for 100 MHz LVPECL oscillator operation at 3.3V with enable/disable functionality. The 6-SMD, No Lead package dimensions (3.20mm x 2.50mm) are identical. The seated height difference (1.10mm vs. 1.20mm) must be verified against PCB clearance requirements. The maximum supply current specification (60mA vs. 50mA) should be considered in power budget analysis.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by exact matching of frequency (100 MHz), output type (LVPECL), supply voltage (3.3V), function (enable/disable), frequency stability (±25ppm), operating temperature range (-40°C ~ 85°C), package type (6-SMD, No Lead), package dimensions (3.20mm x 2.50mm), RoHS compliance (ROHS3), and moisture sensitivity level (1 - Unlimited).

Q: Are there any compliance or certification differences between these parts?

A: No. All three parts are ROHS3 compliant, REACH Unaffected, and classified as EAR99 for export control purposes. All are active production components.

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

A: The Raltron CP3225-100.000-3.3-25-X-T-TR is available in Cut Tape (CT) and Digi-Reel® packaging. The EPSON SG3225EEN 100.000000M-CDGA3 is available in Tape & Reel (TR) packaging. Packaging selection should align with assembly process requirements and inventory management practices.
