Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CPC7591BATR is determined by the following critical parameters:

• Functional Equivalence: Line card access switch functionality
• Voltage Supply Range: 4.5V ~ 5.5V compatibility
• Power Consumption: 10.5 mW maximum
• Operating Temperature Range: -40°C ~ 110°C
• Mounting Type: Surface mount configuration
• Compliance Standards: ROHS3 compliance and REACH unaffected status

The CPC7695BCTR qualifies as a manufacturer-recommended substitute based on matching these core electrical and operational parameters. While the CPC7695BCTR utilizes a 28-SOIC package compared to the 16-SOIC of the original part, both components maintain identical voltage supply, current draw, power consumption, and temperature specifications. The substitute part carries active product status, ensuring continued availability and support.

Parameter Comparison

Engineering Selection Recommendations

The CPC7695BCTR is the manufacturer-recommended substitute for the obsolete CPC7591BATR. Both components maintain identical electrical specifications including voltage supply range, current consumption, power dissipation, and operating temperature limits. Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

The primary design consideration is the package footprint difference: the CPC7695BCTR uses a 28-SOIC package versus the 16-SOIC of the original part. PCB layout modifications are required to accommodate this larger package. The CPC7695BCTR's active product status ensures ongoing manufacturer support and component availability, making it the appropriate choice for new designs and legacy system replacements.

Frequently Asked Questions (FAQ)

Q: Can the CPC7695BCTR directly replace the CPC7591BATR without circuit modifications?

A: Electrical compatibility is confirmed across all specified parameters. However, the package footprint differs (28-SOIC versus 16-SOIC), requiring PCB layout changes. Pin configuration and functional mapping must be verified against detailed datasheets before implementation.

Q: Are there compliance differences between the two parts?

A: Both parts are ROHS3 compliant and REACH unaffected. No compliance barriers exist for substitution.

Q: Why is the CPC7591BATR obsolete?

A: Product status reflects manufacturer discontinuation. The CPC7695BCTR represents the active alternative for line card access switch applications within this voltage and power envelope.

Q: What is the significance of the MSL rating?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage, handling, or assembly processes.

Q: Are the supply voltage and current specifications identical?

A: Yes. Both parts operate at 4.5V to 5.5V supply voltage with 2mA current draw and 10.5 mW power consumption, ensuring direct electrical compatibility.
