Substitute Part Grouping Explanation

The substitute part SXO53C3A481-27.000M from Suntsu Electronics, Inc. is classified as a direct equivalent based on the following substitution criteria:

Matching Critical Parameters:

• Frequency: 27 MHz (exact match)
• Output Type: CMOS (exact match)
• Supply Voltage: 3.3V (exact match)
• Function: Enable/Disable (exact match)
• Frequency Stability: ±50ppm (exact match)
• Operating Temperature Range: -40°C ~ 85°C (exact match)
• Package / Case: 4-SMD, No Lead (exact match)
• Physical Dimensions: 5.00mm x 3.20mm (exact match)
• Height - Seated (Max): 1.40mm (exact match)
• Mounting Type: Surface Mount (exact match)

Acceptable Variation:

• Current - Supply (Max): 16mA (substitute) vs. 20mA (main part). The substitute draws less current, which is acceptable in power budget analysis.

Compliance Status:

• Main part: RoHS Compliant, AEC-Q100 rated
• Substitute part: ROHS3 Compliant, no AEC-Q100 rating specified

Both parts are actively produced and available in production quantities.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (AC-27.000MBE-T): Select the AC-27.000MBE-T when AEC-Q100 automotive-grade qualification is required. This part carries explicit automotive ratings and is supplied in Tape & Reel packaging suitable for automated assembly processes.

Substitute Part Selection (SXO53C3A481-27.000M): The SXO53C3A481-27.000M is electrically and mechanically compatible for applications where AEC-Q100 qualification is not a requirement. The lower maximum supply current (16mA vs. 20mA) provides a margin in power budget calculations. This part is supplied in Bulk packaging and requires manual handling or repackaging for automated assembly.

Compliance Considerations: Both parts maintain RoHS compliance. The main part carries AEC-Q100 certification; the substitute does not. Selection between these parts depends on whether automotive-grade qualification is mandated by the application or end-use environment.

Packaging Impact: The main part is supplied in Tape & Reel format, optimized for high-volume automated assembly. The substitute is supplied in Bulk format, which may require additional handling and repackaging steps in manufacturing environments utilizing automated pick-and-place equipment.

Frequently Asked Questions (FAQ)

Q: Can SXO53C3A481-27.000M be used as a direct replacement for AC-27.000MBE-T?

A: Yes, from an electrical and mechanical standpoint. Both parts share identical frequency (27 MHz), output type (CMOS), supply voltage (3.3V), enable/disable function, frequency stability (±50ppm), operating temperature range (-40°C ~ 85°C), and physical package dimensions (5.00mm x 3.20mm, 1.40mm height). The substitute draws 16mA maximum versus 20mA for the main part, which is acceptable. However, if AEC-Q100 automotive qualification is required, only the AC-27.000MBE-T meets this specification.

Q: What is the difference in current consumption between these parts?

A: The AC-27.000MBE-T has a maximum supply current of 20mA, while the SXO53C3A481-27.000M has a maximum supply current of 16mA. The substitute part consumes less current, which does not create compatibility issues and may reduce power dissipation in the application.

Q: Are the physical packages identical?

A: Yes. Both parts use a 4-SMD, No Lead package with dimensions of 5.00mm x 3.20mm and a maximum seated height of 1.40mm. PCB footprints are identical, and both are surface mount devices suitable for the same assembly processes.

Q: What is the difference in packaging format?

A: The AC-27.000MBE-T is supplied in Tape & Reel (TR) format, which is standard for automated assembly lines. The SXO53C3A481-27.000M is supplied in Bulk format, which requires manual handling or repackaging before use in automated pick-and-place equipment.

Q: Does the substitute part have AEC-Q100 certification?

A: No. The AC-27.000MBE-T carries AEC-Q100 automotive-grade ratings. The SXO53C3A481-27.000M does not list AEC-Q100 certification. If your application requires automotive-grade qualification, the AC-27.000MBE-T is the appropriate selection.

Q: Are both parts RoHS compliant?

A: Yes. The AC-27.000MBE-T is RoHS Compliant. The SXO53C3A481-27.000M is ROHS3 Compliant. Both meet RoHS regulatory requirements.

Q: What frequency stability do these oscillators provide?

A: Both parts provide ±50ppm frequency stability across the operating temperature range of -40°C to 85°C.
