Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 7W-75.000MBD-T are qualified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

Critical Matching Parameters:

• Frequency: 75 MHz (exact match required)
• Output Type: CMOS
• Supply Voltage: 3.3V
• Function: Enable/Disable capability
• Frequency Stability: ±25ppm
• Operating Temperature Range: -40°C ~ 85°C
• Package / Case: 4-SMD, No Lead
• Physical Dimensions: 7.00mm x 5.00mm footprint
• Base Resonator: Crystal
• Type: XO (Standard)
• Moisture Sensitivity Level: 1 (Unlimited)

All substitute parts listed meet these electrical and mechanical requirements. Substitution is valid where these parameters align with the original specification. Physical height variations within the 4-SMD, No Lead package envelope are acceptable provided the component maintains the same footprint and electrical interface.

Engineering Selection Recommendations

510CBA75M0000AAGR (Skyworks Solutions Inc.)

This substitute part is classified as Active product status, ensuring ongoing manufacturer support and supply chain availability. The Si510 series oscillator meets all electrical specifications of the 7W-75.000MBD-T, including 75 MHz frequency, 3.3V supply, CMOS output, and enable/disable function. Maximum supply current is 26mA compared to 20mA for the original part. Physical height is 1.80mm, which is within acceptable tolerance for the 4-SMD, No Lead package envelope. Compliance certifications are not specified in available documentation.

CPPFXC7LZ-A7BR-75.0TS (Cardinal Components Inc.)

This substitute part is classified as Active product status with documented ROHS3 compliance and REACH Unaffected status. The FIPO™ CPPFX series oscillator meets all electrical specifications of the 7W-75.000MBD-T. Maximum supply current is 25mA. Physical height is 1.90mm, which is within acceptable tolerance for the 4-SMD, No Lead package envelope. Current consumption in disable mode is specified at 50µA. This part is available in Tape & Reel packaging format.

Both substitute parts are electrically and mechanically compatible with the 7W-75.000MBD-T. Selection between them depends on specific compliance requirements, packaging format preferences, and supply chain considerations.

Frequently Asked Questions (FAQ)

Q: Can the 510CBA75M0000AAGR directly replace the 7W-75.000MBD-T on existing PCBs?

A: Yes. Both parts share identical footprint dimensions (7.00mm x 5.00mm), 4-SMD No Lead package configuration, and electrical specifications (75 MHz, 3.3V, CMOS output, enable/disable function). The height difference (1.80mm vs 1.42mm) is within the package envelope tolerance for this component class.

Q: What is the primary difference between the two substitute parts?

A: The CPPFXC7LZ-A7BR-75.0TS offers documented ROHS3 compliance and REACH Unaffected certification. The 510CBA75M0000AAGR provides lower maximum supply current (26mA vs 25mA) and includes disable mode current specification (18mA). Both meet the core electrical and mechanical requirements.

Q: Are there any supply current considerations when substituting?

A: The original 7W-75.000MBD-T specifies maximum supply current of 20mA. Both substitute parts have slightly higher maximum supply current ratings (25-26mA). Designs with tight power budgets should verify that the additional current draw is acceptable for the application. The CPPFXC7LZ-A7BR-75.0TS specifies 50µA disable mode current, which may be relevant for low-power applications.

Q: What packaging formats are available for the substitute parts?

A: Both substitute parts are available in Tape & Reel (TR) packaging format, suitable for automated assembly processes. The original 7W-75.000MBD-T packaging format is not specified in available documentation.

Q: Are there any compliance or regulatory differences?

A: The original 7W-75.000MBD-T is RoHS Compliant and REACH Unaffected. The CPPFXC7LZ-A7BR-75.0TS is ROHS3 Compliant and REACH Unaffected. The 510CBA75M0000AAGR compliance status is not specified. For applications with specific regulatory requirements, the CPPFXC7LZ-A7BR-75.0TS provides documented compliance.

Q: Can these parts be used interchangeably in production?

A: Yes, provided that the application does not have specific constraints regarding maximum supply current, physical height clearance, or regulatory compliance documentation. Both substitute parts meet the electrical and mechanical specifications of the 7W-75.000MBD-T for 75 MHz CMOS oscillator applications with 3.3V supply and enable/disable functionality.
