7W-8.000MBE-T CMOS Oscillator Equivalent & Substitute Parts

Part Overview

The 7W-8.000MBE-T is an 8 MHz XO (Standard) CMOS oscillator manufactured by TXC CORPORATION. This surface mount device operates at 3.3V with enable/disable functionality and is housed in a 4-SMD, No Lead package. The part is currently classified as obsolete, making identification of equivalent substitute components essential for ongoing production support, design updates, and inventory management. Substitute parts must maintain identical electrical performance and mechanical compatibility to ensure direct replacement capability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7W-8.000MBE-T is determined by strict alignment of the following critical parameters:

Electrical Parameters:

• Frequency: 8 MHz (exact match required)
• Output: CMOS (exact match required)
• Supply Voltage: 3.3V (exact match required)
• Function: Enable/Disable (exact match required)
• Frequency Stability: ±50ppm (exact match required)
• Operating Temperature: -40°C ~ 85°C (exact match required)

Mechanical Parameters:

• Package Type: 4-SMD, No Lead (exact match required)
• Package Dimensions: 7.00mm x 5.00mm (exact match required)
• Mounting Type: Surface Mount (exact match required)

Compliance Parameters:

• RoHS Status: RoHS Compliant (minimum requirement)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

The CPPC7L-A7BP-8.0TS from Cardinal Components Inc. qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. Variations in maximum supply current (25mA vs. 20mA), maximum seated height (1.90mm vs. 1.42mm), and disable current (50µA) do not disqualify substitution, as these represent acceptable operational tolerances within the 4-SMD, No Lead package category.

Parameter Comparison

Engineering Selection Recommendations

The CPPC7L-A7BP-8.0TS is a qualified substitute for the obsolete 7W-8.000MBE-T based on the following engineering criteria:

Product Status Alignment: The 7W-8.000MBE-T is classified as obsolete. The CPPC7L-A7BP-8.0TS maintains active product status with current manufacturing availability, ensuring long-term supply chain continuity.

Electrical Compatibility: All critical electrical parameters align exactly: 8 MHz frequency, CMOS output, 3.3V supply voltage, enable/disable function, ±50ppm frequency stability, and -40°C ~ 85°C operating temperature range. The maximum supply current specification of 25mA (versus 20mA for the original) represents acceptable operational margin within the CMOS oscillator category.

Mechanical Compatibility: Both parts utilize identical 4-SMD, No Lead package geometry with 7.00mm x 5.00mm footprint and surface mount configuration. The maximum seated height of 1.90mm for the substitute (versus 1.42mm for the original) remains within acceptable PCB assembly clearance tolerances for standard surface mount applications.

Compliance Certification: The CPPC7L-A7BP-8.0TS meets ROHS3 compliance, exceeding the RoHS Compliant requirement of the original part. Both parts maintain REACH Unaffected status, EAR99 export classification, and identical HTSUS commodity code 8542.39.0001. Moisture Sensitivity Level 1 (Unlimited) matches exactly, eliminating special handling requirements.

Packaging Format: The substitute is available in Tape & Reel (TR) packaging, supporting automated assembly processes equivalent to the original part's packaging configuration.

Frequently Asked Questions (FAQ)

Q: Can the CPPC7L-A7BP-8.0TS be used as a direct replacement for the 7W-8.000MBE-T without circuit modifications?

A: Yes. The CPPC7L-A7BP-8.0TS qualifies as a direct substitute. All critical electrical parameters (frequency, output type, supply voltage, function, stability, and temperature range) match exactly. The 4-SMD, No Lead package geometry and surface mount configuration are identical, enabling direct PCB footprint compatibility without design changes.

Q: What is the significance of the height difference (1.42mm vs. 1.90mm)?

A: The substitute part has a maximum seated height of 1.90mm compared to 1.42mm for the original. This 0.48mm difference remains within standard PCB assembly clearance specifications for surface mount oscillators. Verify clearance in your specific PCB layout if height-constrained applications are present.

Q: Does the higher maximum supply current (25mA vs. 20mA) affect circuit design?

A: No. The substitute's 25mA maximum supply current specification represents acceptable operational margin. Circuit designs accommodating the original 20mA specification will operate within safe parameters with the substitute part. Power supply and decoupling capacitor sizing based on the original specification remains valid.

Q: Are there any compliance or certification differences between the two parts?

A: The CPPC7L-A7BP-8.0TS meets ROHS3 compliance, which exceeds the RoHS Compliant requirement of the original part. Both parts maintain identical REACH Unaffected status, EAR99 export classification, and Moisture Sensitivity Level 1 (Unlimited). No additional handling or compliance procedures are required.

Q: What is the availability status of the substitute part?

A: The CPPC7L-A7BP-8.0TS is classified as an active product with current manufacturing support. Inventory availability is confirmed at 1021 pieces in new original condition, providing reliable supply chain access compared to the obsolete 7W-8.000MBE-T.

Q: Are there any functional differences in the enable/disable feature?

A: No. Both parts implement identical enable/disable functionality with CMOS output control. The substitute includes a maximum disable current specification of 50µA, which is not provided for the original part but represents standard low-power standby operation within the CMOS oscillator category.

Q: Can the substitute part be used in existing inventory management systems?

A: Yes. The CPPC7L-A7BP-8.0TS maintains identical HTSUS commodity code (8542.39.0001) and EAR99 export classification, enabling direct substitution in procurement, inventory tracking, and regulatory documentation systems.
