Substitute Part Grouping Explanation

Substitute parts for the AX3DAF4-155.5200T are identified based on strict alignment of the following critical parameters:

• Frequency: 155.52 MHz (exact match required)
• Output Configuration: LVDS (exact match required)
• Supply Voltage: 3.3V (exact match required)
• Frequency Stability: ±25ppm (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Enable/Disable Function: Present (exact match required)
• Package Type: 6-SMD, No Lead (exact match required)
• Physical Footprint: 3.20mm x 2.50mm (exact match required)
• Regulatory Compliance: ROHS3 Compliant, REACH Unaffected (exact match required)

The CL3225-155.520-3.3-25-X-T-TR from Raltron Electronics meets all substitution criteria and is classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the AX3DAF4-155.5200T and CL3225-155.520-3.3-25-X-T-TR are Active products with full regulatory compliance (ROHS3 Compliant, REACH Unaffected, EAR99 classification). Selection between these parts should be based on:

• Availability: AX3DAF4-155.5200T has 731 units in stock; CL3225-155.520-3.3-25-X-T-TR has 885 units in stock
• Supply Current: AX3DAF4-155.5200T draws 27mA maximum; CL3225-155.520-3.3-25-X-T-TR draws 40mA maximum
• Physical Height: AX3DAF4-155.5200T seated height is 1.10mm; CL3225-155.520-3.3-25-X-T-TR seated height is 1.20mm
• Packaging Format: AX3DAF4-155.5200T is supplied in standard packaging; CL3225-155.520-3.3-25-X-T-TR is supplied in Cut Tape (CT)

Both parts are functionally equivalent for applications requiring 155.52 MHz LVDS oscillation at 3.3V with Enable/Disable control across the -40°C to 85°C temperature range.

Frequently Asked Questions (FAQ)

Q: Can the CL3225-155.520-3.3-25-X-T-TR replace the AX3DAF4-155.5200T in existing designs?

A: Yes. Both parts share identical electrical specifications (frequency, output type, voltage, stability, temperature range, and function) and identical mechanical footprints (3.20mm x 2.50mm, 6-SMD No Lead package). The maximum seated height difference (1.10mm vs 1.20mm) and supply current difference (27mA vs 40mA) must be verified against your PCB clearance and power budget requirements.

Q: What are the critical parameters that define substitution eligibility?

A: Substitution eligibility is determined by exact matching of: frequency (155.52 MHz), output configuration (LVDS), supply voltage (3.3V), frequency stability (±25ppm), operating temperature range (-40°C ~ 85°C), Enable/Disable function, package type (6-SMD No Lead), physical footprint (3.20mm x 2.50mm), and regulatory compliance status (ROHS3, REACH Unaffected).

Q: Are there differences in supply current consumption between these parts?

A: Yes. The AX3DAF4-155.5200T has a maximum supply current of 27mA, while the CL3225-155.520-3.3-25-X-T-TR has a maximum supply current of 40mA. Applications with strict power constraints should account for this 13mA difference in worst-case current draw.

Q: What is the physical height difference, and does it matter?

A: The AX3DAF4-155.5200T has a maximum seated height of 1.10mm, while the CL3225-155.520-3.3-25-X-T-TR has a maximum seated height of 1.20mm. This 0.10mm difference is negligible for most applications but should be verified if your PCB design has tight vertical clearance constraints.

Q: Are both parts available in the same packaging format?

A: No. The AX3DAF4-155.5200T is supplied in standard packaging, while the CL3225-155.520-3.3-25-X-T-TR is supplied in Cut Tape (CT) format. Verify your assembly process compatibility with the available packaging option.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both parts are ROHS3 Compliant, REACH Unaffected, and classified as EAR99 for export control purposes. Both have Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements.
