Engineering Selection Recommendations

Primary Substitutes (Active Status, Highest Compatibility):

The 654E15003I3T and 654P15003I3T from CTS-Frequency Controls are direct functional equivalents with Active product status. Both parts are manufactured by an established frequency control supplier and maintain identical electrical specifications. The 654 series offers reduced seated height (1.30mm vs. 1.40mm) and slightly elevated maximum supply current (88mA vs. 80mA). These parts are available in Tape & Reel packaging, suitable for production environments.

The SXO53P3A481-150.000M from Suntsu Electronics, Inc. provides an alternative with Active status and identical current supply specification (80mA). This part features the lowest seated height (1.20mm) among all candidates, offering potential PCB layout advantages in space-constrained applications. Bulk packaging is specified for this part number.

Secondary Substitutes (Active Status, Parametric Equivalence):

The 653E15003I3T and 653P15003I3T from CTS-Frequency Controls are parametric equivalents with Active status. Both maintain the original seated height specification (1.40mm) matching the CB-150.000MBE-T. Maximum supply current is specified at 88mA. These parts are available in Tape & Reel packaging.

Alternative Substitute (Active Status, Higher Current Specification):

The XUP535150.000JS6I8 from Renesas Electronics Corporation is an Active substitute with identical core electrical specifications. This part specifies maximum supply current at 115mA, which is elevated relative to the original specification. The XUP series features the lowest seated height (1.20mm). Selection of this part requires confirmation that the elevated current specification does not conflict with power supply design constraints.

Compliance and Certification:

All substitute parts maintain RoHS3 Compliance status, which is equivalent to the original RoHS Compliant designation. All parts are classified as REACH Unaffected and carry ECCN EAR99 designation, matching the original part's regulatory status. Moisture Sensitivity Level 1 (Unlimited) is maintained across all candidates where specified.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts as a direct replacement for the CB-150.000MBE-T?

A: Yes. All listed substitute parts satisfy the mandatory matching parameters: 150 MHz frequency, LVPECL output, 3.3V supply, Enable/Disable function, ±50ppm frequency stability, -40°C to 85°C operating range, 6-SMD No Lead package, and 5.00mm x 3.20mm dimensions. Electrical and mechanical interchangeability is confirmed.

Q: What is the difference between the 654E15003I3T and 654P15003I3T?

A: Both parts are manufactured by CTS-Frequency Controls with identical electrical specifications and Active product status. The designation difference (654E vs. 654P) reflects internal CTS product line differentiation. Both are available in Tape & Reel packaging and maintain the same 1.30mm seated height and 88mA maximum supply current. Selection between these parts may be determined by supplier availability or internal procurement specifications.

Q: Why does the XUP535150.000JS6I8 specify 115mA maximum supply current when the original part specifies 80mA?

A: The XUP535150.000JS6I8 is manufactured by Renesas Electronics Corporation and reflects that manufacturer's design specification for this frequency and output type. The elevated current specification does not indicate incompatibility; rather, it represents the maximum current the part may draw under specified operating conditions. Circuit design must accommodate this specification. Confirmation with power supply design parameters is required before selection.

Q: What is the significance of seated height variation among these parts?

A: All substitute parts maintain seated heights between 1.20mm and 1.40mm, which falls within the allowable mechanical envelope for 6-SMD No Lead packages. The SXO53P3A481-150.000M and XUP535150.000JS6I8 offer reduced height (1.20mm), which may provide advantages in applications with tight vertical clearance constraints. The 654 series and 653 series maintain heights of 1.30mm and 1.40mm respectively. PCB layout review is recommended to confirm clearance compatibility.

Q: Are there any differences in packaging format among these substitutes?

A: Yes. The 654E15003I3T, 654P15003I3T, 653E15003I3T, and 653P15003I3T are supplied in Tape & Reel (TR) format, suitable for automated assembly processes. The SXO53P3A481-150.000M is supplied in Bulk format. The XUP535150.000JS6I8 packaging format is not specified in the provided data. Procurement and assembly process requirements should determine packaging preference.

Q: What is the product status significance for component selection?

A: The CB-150.000MBE-T is classified as Obsolete, indicating TXC CORPORATION no longer manufactures this part. All listed substitutes carry Active status, confirming ongoing manufacturing and availability from their respective manufacturers. Active status ensures continued supply for production and design support activities.

Q: Do all substitute parts maintain RoHS compliance?

A: Yes. All substitute parts are classified as ROHS3 Compliant, which is equivalent to the original RoHS Compliant designation. All parts are REACH Unaffected and carry ECCN EAR99 classification, matching the regulatory status of the original CB-150.000MBE-T.

Q: Can I mix different substitute parts within a single production run?

A: All listed parts are electrically and mechanically interchangeable and satisfy identical functional requirements. However, mixing parts from different manufacturers within a single production run may introduce variables in supply chain management, testing protocols, and long-term reliability tracking. Standardization on a single substitute part number per production batch is recommended for quality assurance and traceability purposes.
