Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (7X50020002): The 7X50020002 from TXC CORPORATION is the original specified component. This part maintains Active product status with confirmed RoHS Compliance and REACH Unaffected regulatory standing. Current inventory of 1016 pieces supports immediate procurement for production requirements.

Substitute Part Selection (SXO32C3A071-50.000M): The SXO32C3A071-50.000M from Suntsu Electronics, Inc. is a qualified direct substitute. This part matches all critical electrical parameters (50 MHz frequency, CMOS output, 3.3V supply, Enable/Disable function, ±50ppm stability, 0°C ~ 70°C operating range) and mechanical specifications (4-SMD No Lead package, 3.20mm x 2.50mm dimensions).

The maximum seated height of the Suntsu part is 1.20mm compared to 1.10mm for the TXC part. This 0.10mm difference is within typical PCB assembly tolerances and does not impact circuit board layout or component clearance in standard applications.

Both parts maintain equivalent regulatory compliance: RoHS3 Compliant (Suntsu) and RoHS Compliant (TXC), REACH Unaffected status, and EAR99 ECCN classification. The Suntsu part provides higher inventory availability (7322 pieces) and specifies maximum supply current of 17mA.

Selection Basis:

• Use 7X50020002 when TXC CORPORATION sourcing is required or preferred
• Use SXO32C3A071-50.000M when Suntsu Electronics sourcing is required or when higher inventory availability is advantageous
• Both parts are suitable for direct substitution in 50 MHz CMOS oscillator applications requiring 3.3V supply with Enable/Disable control

Frequently Asked Questions (FAQ)

Q: Can the SXO32C3A071-50.000M replace the 7X50020002 in existing designs?

A: Yes. The SXO32C3A071-50.000M is a direct substitute. All electrical specifications match exactly: 50 MHz frequency, CMOS output, 3.3V supply voltage, Enable/Disable function, ±50ppm frequency stability, and 0°C ~ 70°C operating temperature range. Mechanical compatibility is confirmed through identical package type (4-SMD, No Lead) and physical dimensions (3.20mm x 2.50mm). The 0.10mm difference in seated height (1.20mm vs 1.10mm) does not affect PCB assembly or component placement.

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

A: Substitution eligibility is determined by exact matching of: frequency (50 MHz), output type (CMOS), supply voltage (3.3V), function (Enable/Disable), frequency stability (±50ppm), operating temperature range (0°C ~ 70°C), mounting type (Surface Mount), package type (4-SMD, No Lead), and physical dimensions (3.20mm x 2.50mm). All these parameters must match precisely for a part to qualify as a direct substitute.

Q: Are there any compliance or regulatory differences between these parts?

A: Both parts maintain equivalent regulatory compliance. The 7X50020002 is RoHS Compliant, while the SXO32C3A071-50.000M is ROHS3 Compliant. Both are REACH Unaffected and classified as EAR99 for export control purposes. Both share the same HTSUS code (8542.39.0001). These differences represent regulatory evolution and do not impact functional compatibility.

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

A: The SXO32C3A071-50.000M specifies a maximum supply current of 17mA. The 7X50020002 does not provide a specified maximum supply current value in the available documentation. For applications with strict power consumption requirements, the Suntsu part provides a defined current specification for design verification.

Q: How do the physical dimensions affect PCB layout?

A: Both parts share identical footprint dimensions of 3.20mm length by 2.50mm width, ensuring identical PCB layout compatibility. The seated height difference of 0.10mm (1.10mm for TXC vs 1.20mm for Suntsu) is within standard PCB assembly tolerances and does not require layout modifications. Component clearance to adjacent parts or enclosure elements should be verified based on specific application requirements.

Q: Which part should be selected for new designs?

A: Either part is suitable for new designs. Selection should be based on: (1) preferred manufacturer relationship, (2) inventory availability requirements, (3) supply chain considerations, or (4) specific application constraints. Both parts are Active status products with confirmed availability and equivalent technical specifications.

Q: Is there any performance difference between these oscillators?

A: No performance difference exists within the specified parameters. Both parts deliver identical frequency (50 MHz), output type (CMOS), supply voltage (3.3V), frequency stability (±50ppm), and operating temperature range (0°C ~ 70°C). The Suntsu part provides specified maximum supply current (17mA), while the TXC part does not specify this parameter in available documentation.
