Key Parameters

Substitute Part Grouping Explanation

Substitution of the 7X20005001 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Frequency: 20 MHz (exact match required)
• Output Type: CMOS
• Supply Voltage: 3.3V
• Function: Enable/Disable capability
• Frequency Stability: ±30ppm
• Operating Temperature Range: -40°C ~ 85°C
• Package Type: 4-SMD, No Lead
• Physical Dimensions: 0.126" L x 0.098" W (3.20mm x 2.50mm)
• Mounting Type: Surface Mount

The substitute part SXO32C3B481-20.000M from Suntsu Electronics, Inc. meets all mandatory matching parameters and is therefore classified as a direct equivalent for the 7X20005001.

Parameter Comparison

Engineering Selection Recommendations

Primary Part: 7X20005001 (TXC CORPORATION)

The 7X20005001 is the specified component with Active product status and established supply availability (1078 pieces in stock). This part is RoHS Compliant and carries MSL 1 (Unlimited) moisture sensitivity rating, indicating robust handling characteristics for manufacturing environments.

Substitute Part: SXO32C3B481-20.000M (Suntsu Electronics, Inc.)

The SXO32C3B481-20.000M is a direct functional equivalent meeting all critical electrical and mechanical parameters. This part is also Active in product status with higher inventory availability (1566 pieces in stock) and carries ROHS3 Compliant certification. The maximum seated height differential of 0.004" (0.10mm) is within standard PCB assembly tolerances and does not impact board-level compatibility.

Both parts are suitable for applications requiring 20 MHz CMOS oscillators with 3.3V supply, Enable/Disable functionality, and industrial temperature operation. Selection between these parts may be based on supply chain availability, procurement lead times, or established vendor relationships, as both meet identical functional and compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can the SXO32C3B481-20.000M be used as a direct replacement for the 7X20005001 in existing designs?

A: Yes. Both parts share identical electrical specifications (20 MHz frequency, CMOS output, 3.3V supply, Enable/Disable function, ±30ppm stability, -40°C to 85°C operating range) and package dimensions (0.126" L x 0.098" W, 4-SMD No Lead). The height difference of 0.004" is within standard PCB assembly tolerances and does not affect board-level compatibility.

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

A: Substitution eligibility is determined by exact matching of: frequency (20 MHz), output type (CMOS), supply voltage (3.3V), function (Enable/Disable), frequency stability (±30ppm), operating temperature range (-40°C to 85°C), package type (4-SMD No Lead), and physical footprint dimensions (0.126" x 0.098").

Q: Are there compliance differences between the two parts?

A: Both parts are RoHS compliant. The 7X20005001 carries RoHS Compliant certification, while the SXO32C3B481-20.000M carries ROHS3 Compliant certification. Both meet ECCN EAR99 and HTSUS 8542.39.0001 classifications. ROHS3 represents an updated compliance standard and does not create incompatibility.

Q: What is the moisture sensitivity level difference?

A: The 7X20005001 is rated MSL 1 (Unlimited), indicating the lowest moisture sensitivity classification. The SXO32C3B481-20.000M moisture sensitivity level is not specified in the provided data. MSL 1 represents optimal handling characteristics; if moisture sensitivity is a critical design consideration, the 7X20005001 is the preferred selection.

Q: How do the supply current specifications compare?

A: The 7X20005001 maximum supply current is not specified in the provided data. The SXO32C3B481-20.000M specifies a maximum supply current of 10mA. For applications with strict power consumption requirements, the specified 10mA value for the Suntsu part provides a defined operating parameter.

Q: Are both parts suitable for industrial temperature applications?

A: Yes. Both parts operate across the identical temperature range of -40°C to 85°C, meeting industrial and extended commercial temperature requirements.
