AX3PAF3-100.0000T Equivalent & Substitute Parts

Part Overview

The AX3PAF3-100.0000T 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 AX3PAF3-100.0000T 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 meet all these criteria and are therefore electrically and mechanically interchangeable with the main part in applications requiring these specifications.

Parameter Comparison

Engineering Selection Recommendations

All three parts—AX3PAF3-100.0000T, CP3225-100.000-3.3-25-X-T-TR, and SG3225EEN 100.000000M-CDGA3—are Active status products with ROHS3 compliance and MSL 1 (Unlimited) rating. They are electrically and mechanically equivalent for 100 MHz LVPECL oscillator applications at 3.3V with Enable/Disable control.

The SG3225EEN 100.000000M-CDGA3 (EPSON) specifies a maximum supply current of 60mA compared to 50mA for the other two parts. This difference does not affect substitution eligibility but should be considered in power budget calculations for applications with tight current constraints.

Height variation exists between the main part (0.043" maximum) and the substitute parts (0.047" maximum). This 0.004" difference must be evaluated against PCB layout and enclosure clearance requirements in the target application.

Frequently Asked Questions (FAQ)

Q: Can CP3225-100.000-3.3-25-X-T-TR replace AX3PAF3-100.0000T directly?

A: Yes. Both parts share identical electrical specifications (100 MHz, LVPECL, 3.3V, ±25ppm stability, -40°C ~ 85°C operating range) and mechanical compatibility (6-SMD, No Lead package, 3.20mm x 2.50mm footprint). The height difference of 0.004" (1.20mm vs 1.10mm) must be verified against PCB clearance requirements.

Q: Can SG3225EEN 100.000000M-CDGA3 replace AX3PAF3-100.0000T directly?

A: Yes. Both parts meet all electrical and mechanical substitution criteria. The EPSON part specifies 60mA maximum supply current versus 50mA for the Abracon part. Applications with power supply constraints should account for this 10mA difference. Height clearance must also be verified.

Q: What are the critical parameters for substitution?

A: 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), and footprint dimensions (3.20mm x 2.50mm) must remain constant. All three parts meet these requirements.

Q: Are there compliance differences between these parts?

A: No. All three parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) rating. ECCN and HTSUS classifications are identical across all parts.

Q: Does packaging format affect substitution?

A: Packaging format (Cut Tape & Digi-Reel® for Raltron, Tape & Reel for EPSON) does not affect electrical or mechanical compatibility. Selection should be based on procurement and assembly workflow requirements.
