Key Parameters

Substitute Part Grouping Explanation

Substitution of the CPC7591BA is determined by the following critical parameters:

Electrical Compatibility:

• Voltage supply range: 4.5V ~ 5.5V (must match)
• Current supply: 2mA (must match)
• Power consumption: 10.5 mW (must match)
• Operating temperature range: -40°C ~ 110°C (must match)
• Function: Line Card Access Switch (must match)

Mechanical Compatibility:

• Mounting type: Surface Mount (must match)
• Manufacturer: IXYS Integrated Circuits Division (preferred for functional equivalence)

Regulatory & Environmental:

• RoHS3 Compliance (must match)
• Moisture Sensitivity Level 1 (must match)

The CPC7695BC qualifies as a manufacturer-recommended substitute based on identical electrical specifications, matching operating parameters, and equivalent functional performance. While the package differs (28-SOIC versus 16-SOIC), both maintain the same 0.295" width and surface mount compatibility, allowing for board-level integration with appropriate layout modifications.

Parameter Comparison

Engineering Selection Recommendations

The CPC7695BC is the manufacturer-recommended substitute for the obsolete CPC7591BA. Both components maintain identical electrical specifications, thermal operating ranges, and regulatory compliance status. The CPC7695BC offers the additional advantage of active product status, ensuring continued availability and manufacturing support.

The primary design consideration is the package transition from 16-SOIC to 28-SOIC. Both packages maintain the same 0.295" width and surface mount compatibility, requiring PCB layout modifications to accommodate the increased pin count. The TTL interface specification of the CPC7695BC aligns with standard telecom interface requirements.

All components listed maintain ROHS3 compliance and MSL Level 1 rating, suitable for standard manufacturing and storage conditions without moisture sensitivity constraints.

Frequently Asked Questions (FAQ)

Q: Can the CPC7695BC directly replace the CPC7591BA without PCB modifications?

A: The CPC7695BC requires PCB layout modifications due to the package change from 16-SOIC to 28-SOIC. While both packages share the same 0.295" width, the increased pin count necessitates updated footprint design and routing.

Q: Are the electrical specifications identical between CPC7591BA and CPC7695BC?

A: Yes. Both components operate at 4.5V to 5.5V supply voltage, consume 2mA current, dissipate 10.5 mW power, and function across -40°C to 110°C operating temperature range.

Q: What is the significance of the CPC7591BA being obsolete?

A: Obsolete status indicates the part is no longer manufactured. The CPC7695BC, with active product status, provides continued availability and manufacturing support for equivalent functionality.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both CPC7591BA and CPC7695BC are ROHS3 compliant, REACH unaffected, and classified as MSL Level 1 with unlimited moisture sensitivity protection.

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

A: The primary difference is the package configuration: CPC7591BA uses 16-SOIC while CPC7695BC uses 28-SOIC. Both maintain identical electrical performance and thermal specifications.
