The identified substitute parts meet all critical electrical and mechanical parameters, ensuring direct compatibility in circuit design and PCB assembly without design modifications.

Parameter Comparison

Engineering Selection Recommendations

All three oscillators—AX3PAF1-100.0000T (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, making them suitable for current and future regulatory requirements.

The CP3225-100.000-3.3-25-X-T-TR from Raltron Electronics provides direct electrical and mechanical compatibility with identical supply current specifications (50mA maximum). This part is available in Cut Tape and Digi-Reel packaging formats.

The SG3225EEN 100.000000M-CDGA3 from EPSON meets all critical electrical and mechanical parameters with a maximum supply current of 60mA, which remains within acceptable operating margins for 3.3V LVPECL applications. This part is supplied in Tape & Reel format.

Height variation between the main part (1.10mm seated height) and substitute parts (1.20mm seated height) is within typical PCB assembly tolerances and does not affect electrical performance or signal integrity.

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts share identical electrical specifications (100 MHz, LVPECL output, 3.3V supply, ±25ppm stability, Enable/Disable function) and mechanical parameters (6-SMD No Lead package, 3.20mm x 2.50mm footprint, surface mount). The 50mA maximum supply current is identical between both devices.

Q: What is the difference between the SG3225EEN 100.000000M-CDGA3 and the AX3PAF1-100.0000T?

A: The primary difference is the maximum supply current specification: the EPSON part is rated at 60mA versus 50mA for the Abracon part. All other electrical parameters (frequency, output type, voltage, stability, temperature range, function) and mechanical parameters (package type, dimensions, mounting) are identical. The 10µA disable current specification is provided only for the Abracon part.

Q: Are there any PCB layout considerations when substituting these parts?

A: The substitute parts have identical footprints (3.20mm x 2.50mm) and mounting types (surface mount, 6-SMD No Lead). Seated height varies slightly (1.10mm for AX3PAF1-100.0000T versus 1.20mm for both substitute parts), which is within standard PCB assembly tolerances and does not require layout modifications.

Q: Do all three parts meet current environmental and regulatory standards?

A: Yes. All three oscillators are ROHS3 compliant and REACH Unaffected, meeting current environmental regulations. Moisture Sensitivity Level 1 (Unlimited) applies to all parts, indicating no special moisture handling requirements during storage or assembly.

Q: Which substitute part should be selected for new designs?

A: Both substitute parts are qualified for new designs. The CP3225-100.000-3.3-25-X-T-TR from Raltron provides identical current specifications to the original part. The SG3225EEN 100.000000M-CDGA3 from EPSON offers higher current capacity (60mA) if additional margin is required. Selection should be based on availability, packaging format preference (Cut Tape vs. Tape & Reel), and supply chain considerations.
