CPC7592BC Equivalent & Substitute Parts

Part Overview

The CPC7592BC is a telecom interface IC designed for line card access switching applications in telecommunications equipment. Manufactured by IXYS Integrated Circuits Division, this 16-SOIC surface mount device operates within a 4.5V to 5.5V supply voltage range and dissipates 10 mW of power across an operating temperature range of -40°C to 110°C.

The CPC7592BC is classified as obsolete. Due to its discontinued status, identifying functionally equivalent substitute components is necessary for system redesign, maintenance, and long-term supply chain planning in telecommunications infrastructure applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CPC7592BC are identified based on the following critical parameters that define functional equivalence:

• Manufacturer: IXYS Integrated Circuits Division (same manufacturer ensures design continuity and support)
• Function: Line Card Access Switch (identical functional purpose)
• Voltage - Supply: 4.5V ~ 5.5V (identical supply voltage compatibility)
• Operating Temperature: -40°C ~ 110°C (identical thermal operating range)
• Mounting Type: Surface Mount (identical PCB assembly compatibility)
• Number of Circuits: 1 (identical circuit count)
• RoHS Status: ROHS3 Compliant (identical environmental compliance)
• Moisture Sensitivity Level: 1 (Unlimited) (identical moisture handling requirements)

The substitute parts CPC7695BC and CPC7695BCTR share all critical electrical and environmental parameters with the CPC7592BC. Both are active products from the same manufacturer, providing continuity for line card access switching applications. The primary difference is the package configuration: the substitutes use 28-SOIC packaging instead of 16-SOIC, which requires PCB layout modification but maintains full functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

The CPC7695BC and CPC7695BCTR are the designated manufacturer-recommended substitutes for the obsolete CPC7592BC. Both substitute parts maintain full compliance with ROHS3 and REACH requirements, ensuring regulatory continuity in telecommunications applications.

The primary consideration for selection between the two substitutes is packaging format. CPC7695BC is supplied in tube packaging, while CPC7695BCTR is supplied in alternative packaging. Both parts are active products with confirmed inventory availability and identical electrical specifications.

The transition from 16-SOIC to 28-SOIC packaging requires PCB layout modification. Design engineers must verify that the increased pin count and package footprint can be accommodated within existing board space constraints. The power dissipation increase from 10 mW to 10.5 mW is negligible and does not require thermal design changes.

Frequently Asked Questions (FAQ)

Q: Can CPC7695BC or CPC7695BCTR be used as direct drop-in replacements for CPC7592BC?

A: No. While both substitute parts are functionally equivalent, they use 28-SOIC packaging instead of the original 16-SOIC package. PCB layout modification is required to accommodate the different footprint and pin configuration.

Q: What is the difference between CPC7695BC and CPC7695BCTR?

A: Both parts are electrically identical with the same 28-SOIC package dimensions. The difference is in packaging format: CPC7695BC is supplied in tube packaging, while CPC7695BCTR uses alternative packaging. Selection depends on assembly line requirements and inventory management preferences.

Q: Are the substitute parts compatible with the same supply voltage as the CPC7592BC?

A: Yes. All three parts operate within the identical 4.5V to 5.5V supply voltage range and maintain the same -40°C to 110°C operating temperature specification.

Q: Do the substitute parts meet the same environmental compliance standards?

A: Yes. CPC7695BC and CPC7695BCTR are both ROHS3 compliant and REACH unaffected, matching the compliance profile of the CPC7592BC.

Q: What is the impact of the package change on thermal performance?

A: Power dissipation increases marginally from 10 mW to 10.5 mW. This 0.5 mW increase is negligible and does not require modifications to thermal management or board layout thermal considerations.

Q: Why is the CPC7592BC obsolete?

A: The CPC7592BC has been discontinued by the manufacturer. The CPC7695 series represents the current active product line for line card access switching applications in telecommunications equipment.
