Key Parameters

Substitute Part Grouping Explanation

Substitution of the CPC7691BB is determined by strict equivalence across the following critical parameters:

• Functional Classification: Line Card Access Switch interface IC
• Interface Protocol: TTL
• Circuit Count: Single circuit configuration
• Electrical Specifications: Voltage supply range 4.5V ~ 5.5V, supply current 2mA, power consumption 10.5 mW
• Operating Temperature Range: -40°C ~ 110°C
• Mounting Technology: Surface mount
• Regulatory Compliance: ROHS3 Compliant, REACH Unaffected

The CPC7695BC qualifies as a substitute based on matching functional classification, interface type, circuit count, electrical specifications, operating temperature range, mounting type, and regulatory compliance status. Package differences (16-SOIC versus 28-SOIC) represent the primary distinction between these components.

Parameter Comparison

Engineering Selection Recommendations

The CPC7695BC is available as an active product from IXYS Integrated Circuits Division, whereas the CPC7691BB is classified as obsolete. Both components maintain ROHS3 compliance and REACH unaffected status, satisfying current regulatory requirements for electronic component manufacturing and distribution.

Selection between these components depends on PCB layout constraints and pin count requirements. The CPC7691BB operates in a 16-pin SOIC package, while the CPC7695BC uses a 28-pin SOIC package. Electrical performance, thermal characteristics, and interface specifications remain equivalent across both components.

Frequently Asked Questions (FAQ)

Q: Can CPC7695BC directly replace CPC7691BB in existing designs?

A: Electrical and functional compatibility is established. PCB layout modifications are required due to package differences (16-SOIC versus 28-SOIC). Pin mapping and circuit board routing must be evaluated for your specific application.

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

A: The CPC7695BC features a 28-pin SOIC package compared to the 16-pin SOIC package of the CPC7691BB. All electrical specifications, operating parameters, and functional characteristics remain identical.

Q: Why is CPC7691BB classified as obsolete?

A: Product status reflects manufacturer discontinuation. The CPC7695BC represents the active equivalent offering from IXYS Integrated Circuits Division for line card access switch applications.

Q: Are both parts RoHS compliant?

A: Yes. Both CPC7691BB and CPC7695BC maintain ROHS3 compliance and REACH unaffected status.

Q: What are the thermal operating limits for these components?

A: Both components operate across the temperature range of -40°C to 110°C, supporting industrial and extended temperature applications.
