Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CPC7691BATR is determined by the following critical parameters:

• Functional Equivalence: Line card access switch function with TTL interface
• Electrical Compatibility: Voltage supply range 4.5V ~ 5.5V, supply current 2mA, power consumption 10.5 mW
• Circuit Configuration: Single circuit configuration
• Operating Temperature Range: -40°C ~ 110°C
• Compliance Standards: ROHS3 compliance, REACH unaffected status, EAR99 classification
• Mounting and Packaging: Surface mount technology with compatible SOIC package footprint

The CPC7695BCTR qualifies as a manufacturer-recommended substitute based on matching all electrical parameters, functional classification, and compliance certifications. The primary distinction is the package variant: 28-SOIC versus the original 16-SOIC configuration.

Parameter Comparison

Engineering Selection Recommendations

The CPC7695BCTR is the manufacturer-recommended substitute for the obsolete CPC7691BATR. Both components maintain identical electrical specifications, functional performance, and compliance certifications. The CPC7695BCTR offers the additional advantage of active product status, ensuring ongoing availability and supply chain continuity.

The primary design consideration is the package transition from 16-SOIC to 28-SOIC. PCB layout modifications are required to accommodate the increased pin count and package dimensions. Both packages maintain the same 0.295" width and 7.50mm standard SOIC pitch, facilitating footprint adaptation in existing designs.

Both components satisfy ROHS3 compliance requirements and maintain unlimited moisture sensitivity classification, supporting deployment in standard manufacturing and storage environments without specialized handling protocols.

Frequently Asked Questions (FAQ)

Q: Can the CPC7695BCTR directly replace the CPC7691BATR without PCB modifications?

A: Direct socket replacement is not possible due to package differences. The CPC7691BATR uses 16-SOIC packaging while the CPC7695BCTR uses 28-SOIC packaging. PCB layout redesign is required to accommodate the different pin configuration and package footprint.

Q: Are the electrical specifications identical between these components?

A: Yes. Both parts operate at 4.5V ~ 5.5V supply voltage, consume 2mA supply current, dissipate 10.5 mW power, and function across the -40°C ~ 110°C temperature range. TTL interface characteristics and line card access switch functionality are equivalent.

Q: What is the significance of the product status difference?

A: The CPC7691BATR is obsolete, indicating discontinued manufacturing and limited availability. The CPC7695BCTR maintains active status, ensuring reliable procurement, technical support, and long-term supply chain availability for new designs and legacy system maintenance.

Q: Do both components meet current compliance standards?

A: Yes. Both the CPC7691BATR and CPC7695BCTR are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. Moisture sensitivity level 1 (unlimited) applies to both components.

Q: What design factors should be evaluated when transitioning from CPC7691BATR to CPC7695BCTR?

A: Primary considerations include PCB footprint redesign for the 28-SOIC package, verification of pin assignment compatibility with the line card access switch function, and confirmation that the increased pin count accommodates system requirements. Electrical and thermal performance remain unchanged.
