Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AX3PAF1-100.0000T3 are qualified based on strict electrical and mechanical parameter alignment. The following criteria determine substitution eligibility:

Critical Parameters (Must Match Exactly):

• Frequency: 100 MHz
• Output Type: LVPECL
• Supply Voltage: 3.3V
• Function: Enable/Disable
• Frequency Stability: ±25ppm
• Operating Temperature Range: -40°C ~ 85°C
• Package / Case: 6-SMD, No Lead
• Size / Dimension: 0.126" L x 0.098" W (3.20mm x 2.50mm)
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

All identified substitute parts meet these critical parameters and are therefore electrically and mechanically compatible with the AX3PAF1-100.0000T3 in applications requiring 100 MHz LVPECL oscillators with 3.3V operation and Enable/Disable control.

Parameter Comparison

Engineering Selection Recommendations

All three parts—AX3PAF1-100.0000T3 (Abracon), CP3225-100.000-3.3-25-X-T-TR (Raltron), and SG3225EEN 100.000000M-CDGA3 (EPSON)—are Active status products with ROHS3 compliance and REACH Unaffected designation. They are suitable for direct substitution in applications requiring 100 MHz LVPECL oscillators with 3.3V operation.

The primary distinction 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 with tight current constraints.

Height variation exists between the Abracon part (0.043" / 1.10mm) and both substitute parts (0.047" / 1.20mm). This 0.004" (0.10mm) difference is within typical PCB assembly tolerances and does not preclude mechanical substitution in standard surface mount applications.

Frequently Asked Questions (FAQ)

Q: Can the CP3225-100.000-3.3-25-X-T-TR be used as a direct replacement for the AX3PAF1-100.0000T3?

A: Yes. Both parts meet identical electrical specifications: 100 MHz frequency, LVPECL output, 3.3V supply, Enable/Disable function, ±25ppm stability, and -40°C ~ 85°C operating range. Both are housed in 6-SMD, No Lead packages with matching footprints (3.20mm x 2.50mm). The 0.004" height difference is within standard PCB assembly tolerances.

Q: Can the SG3225EEN 100.000000M-CDGA3 be used as a direct replacement for the AX3PAF1-100.0000T3?

A: Yes. The EPSON part meets all critical electrical specifications and package requirements. The maximum supply current specification is 60mA versus 50mA for the Abracon part. This higher rating does not affect compatibility but indicates slightly higher power consumption under maximum load conditions.

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

A: Substitution compatibility is determined by: 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 physical dimensions (3.20mm x 2.50mm). All substitute parts match these parameters exactly.

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. Moisture sensitivity level is 1 (Unlimited) for all parts, indicating no special moisture handling requirements.

Q: Does the height difference between parts affect PCB assembly?

A: The Abracon part has a maximum seated height of 0.043" (1.10mm), while both substitute parts have 0.047" (1.20mm). This 0.004" (0.10mm) difference is within standard PCB assembly tolerances and does not require design modifications for typical surface mount applications.
