7W-40.000MBE-T CMOS Oscillator Equivalent & Substitute Parts

Part Overview

The 7W-40.000MBE-T is a 40 MHz XO (Standard) CMOS oscillator manufactured by TXC CORPORATION, designed for applications requiring a 3.3V enable/disable crystal oscillator in a 4-SMD, no-lead surface mount package. This part operates across the industrial temperature range of -40°C to 85°C with ±50ppm frequency stability and a maximum supply current of 20mA.

The 7W-40.000MBE-T is classified as obsolete. Substitute parts are necessary to maintain design continuity and ensure long-term component availability for new production runs and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 7W-40.000MBE-T is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Criteria:

• Frequency: 40 MHz
• Output Type: CMOS
• Supply Voltage: 3.3V
• Function: Enable/Disable
• Frequency Stability: ±50ppm
• Operating Temperature Range: -40°C ~ 85°C
• Package / Case: 4-SMD, No Lead
• Mounting Type: Surface Mount
• Physical Dimensions: 0.276" L x 0.197" W (7.00mm x 5.00mm)
• Moisture Sensitivity Level: 1 (Unlimited)

All four substitute parts listed below meet these mandatory criteria and are therefore direct functional equivalents for the obsolete 7W-40.000MBE-T.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts are active products from established manufacturers and provide direct functional equivalence to the obsolete 7W-40.000MBE-T. Selection among these alternatives should be based on the following factors:

Product Status & Availability: All substitute parts carry active product status, ensuring long-term availability and continued manufacturing support. The 7W-40.000MBE-T obsolete status necessitates transition to one of these active alternatives.

Compliance & Certifications: All substitute parts are RoHS compliant. The Cardinal Components parts (CPPC7L-A7BP-40.0000TS and CPPLC7L-A7BP-40.0TS) and Suntsu part (SXO75C3A481-40.000M) carry ROHS3 compliance. The Skyworks part (510CAA40M0000AAGR) carries RoHS compliance. All parts are REACH Unaffected or carry equivalent environmental compliance.

Supply Current Considerations: The original 7W-40.000MBE-T specifies a maximum supply current of 20mA. All substitute parts operate at 25mA or 26mA maximum supply current, representing a minor increase. The Skyworks 510CAA40M0000AAGR specifies 26mA maximum and includes a disable current specification of 18mA. The Cardinal parts specify 50µA disable current, providing lower power consumption in disabled mode.

Physical Height Variation: The original part specifies a maximum seated height of 0.056" (1.42mm). Substitute parts range from 0.063" to 0.075" in maximum seated height. Verify PCB clearance and assembly constraints before selection.

Packaging Format: The original part is supplied in Cut Tape (CT) format. Substitute parts are supplied in Tape & Reel (TR) format or Bulk. Confirm packaging requirements for procurement and assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the 510CAA40M0000AAGR from Skyworks Solutions directly replace the 7W-40.000MBE-T?

A: Yes. The 510CAA40M0000AAGR meets all mandatory equivalence criteria: 40 MHz frequency, CMOS output, 3.3V supply, enable/disable function, ±50ppm stability, -40°C to 85°C operating range, 4-SMD no-lead package, and identical physical dimensions. The maximum supply current increases from 20mA to 26mA. Verify power budget compatibility in your application.

Q: What is the difference between the two Cardinal Components substitutes: CPPC7L-A7BP-40.0000TS and CPPLC7L-A7BP-40.0TS?

A: Both parts are functionally equivalent and meet all mandatory substitution criteria. They differ in series designation (FIPO™ CPP versus FIPO™ CPPL) but share identical electrical specifications, frequency stability, operating temperature range, and physical dimensions. Both specify 25mA maximum supply current and 50µA disable current. Consult Cardinal Components technical documentation for series-specific design considerations.

Q: Does the increased supply current of substitute parts affect circuit design?

A: The substitute parts specify maximum supply currents of 25mA to 26mA, compared to the original 20mA specification. This represents a 5-6mA increase. Verify that your power supply and current-limiting circuits can accommodate this increase. If your design operates at the original 20mA specification, the substitute parts will operate within their rated limits at lower current draw.

Q: Are there packaging format differences between the original and substitute parts?

A: Yes. The original 7W-40.000MBE-T is supplied in Cut Tape (CT) format. The Skyworks 510CAA40M0000AAGR is supplied in Tape & Reel (TR) format. The Cardinal Components parts (CPPC7L-A7BP-40.0000TS and CPPLC7L-A7BP-40.0TS) are supplied in Tape & Reel (TR) format. The Suntsu SXO75C3A481-40.000M is supplied in Bulk format. Confirm packaging compatibility with your assembly process and procurement requirements.

Q: What is the significance of the height difference between the original and substitute parts?

A: The original 7W-40.000MBE-T specifies a maximum seated height of 0.056" (1.42mm). Substitute parts range from 0.063" to 0.075" in maximum seated height. This represents an increase of 0.007" to 0.019" (0.18mm to 0.48mm). Verify that your PCB layout, component placement, and assembly constraints accommodate the taller substitute parts. Height differences may affect clearance to adjacent components or enclosure constraints.

Q: Are all substitute parts RoHS compliant?

A: Yes. The Skyworks 510CAA40M0000AAGR carries RoHS compliance. The Cardinal Components parts (CPPC7L-A7BP-40.0000TS and CPPLC7L-A7BP-40.0TS) and Suntsu part (SXO75C3A481-40.000M) carry ROHS3 compliance. All parts meet RoHS environmental standards. Verify compliance requirements for your specific application and regulatory jurisdiction.

Q: Can I use these substitute parts in new designs, or only as replacements for the obsolete 7W-40.000MBE-T?

A: All substitute parts carry active product status and are suitable for both new designs and replacement applications. Active product status ensures continued manufacturing support, long-term availability, and stable pricing. These parts are recommended for all new designs requiring a 40 MHz CMOS oscillator with 3.3V supply and enable/disable function.
