CPC7592BB Equivalent & Substitute Parts

Part Overview

The CPC7592BB is a telecom interface IC manufactured by IXYS Integrated Circuits Division, designed as a line card access switch in a 16-SOIC package. This component operates within the 4.5V to 5.5V supply voltage range and dissipates 10 mW of power across a single circuit configuration. The CPC7592BB is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations where legacy component replacement is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CPC7592BB is based on the following critical parameters that define functional equivalence:

Electrical Compatibility:

• Supply voltage range: 4.5V ~ 5.5V (must match exactly)
• Number of circuits: 1 (single circuit configuration required)
• Operating temperature range: -40°C ~ 110°C (must encompass or match)
• Function: Line Card Access Switch (identical functional purpose)

Mechanical & Environmental Compatibility:

• Surface mount technology (required for PCB integration)
• RoHS3 compliance (regulatory requirement maintained)
• MSL Level 1 (storage and handling compatibility)

Identified Substitutes: The CPC7695BC and CPC7695BCTR both satisfy the electrical and environmental requirements for substitution. Both are active products from IXYS Integrated Circuits Division with identical supply voltage, operating temperature, and functional classification. The primary difference between the main part and substitutes is the package configuration (16-SOIC versus 28-SOIC) and increased circuit density in the substitute variants.

Parameter Comparison

Engineering Selection Recommendations

The CPC7695BC and CPC7695BCTR are both qualified substitutes for the obsolete CPC7592BB based on maintained electrical specifications and regulatory compliance. Both substitute parts retain ROHS3 compliance and MSL Level 1 classification, ensuring compatibility with existing supply chain and storage requirements.

The transition from 16-SOIC to 28-SOIC packaging represents a physical footprint change that requires PCB layout modification. Both substitute parts are manufactured by the same supplier (IXYS Integrated Circuits Division) and maintain identical supply voltage, operating temperature range, and functional classification as line card access switches.

CPC7695BCTR offers higher inventory availability (10,099 pieces) compared to CPC7695BC (724 pieces), which may influence procurement decisions for volume applications. Both parts are classified as active products, ensuring long-term availability and continued manufacturing support.

Frequently Asked Questions (FAQ)

Q: Can CPC7695BC and CPC7695BCTR be used interchangeably with CPC7592BB?

A: Both CPC7695BC and CPC7695BCTR satisfy the electrical requirements for substitution, including identical supply voltage (4.5V ~ 5.5V), operating temperature range (-40°C ~ 110°C), and functional classification as line card access switches. However, the package change from 16-SOIC to 28-SOIC requires PCB redesign and cannot be implemented as a direct drop-in replacement without layout modifications.

Q: What is the primary difference between CPC7695BC and CPC7695BCTR?

A: Both parts share identical electrical specifications and functional characteristics. The primary distinction is packaging designation and inventory availability. CPC7695BCTR is available in significantly higher quantities (10,099 pieces versus 724 pieces for CPC7695BC), which may affect lead times and procurement strategy.

Q: Are there any compliance or regulatory differences between the main part and substitutes?

A: No. All three parts maintain ROHS3 compliance and MSL Level 1 classification. Regulatory compliance is consistent across the CPC7592BB, CPC7695BC, and CPC7695BCTR, with identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications.

Q: What design considerations are necessary when transitioning from CPC7592BB to CPC7695BC or CPC7695BCTR?

A: The package transition from 16-SOIC to 28-SOIC requires PCB footprint modification. The 28-SOIC package maintains the same 7.50mm width but accommodates additional pin positions. Design review must confirm that the increased pin count and modified pinout are compatible with the target application circuit topology.

Q: Why is CPC7592BB classified as obsolete?

A: The CPC7592BB is no longer in active production. The CPC7695 series (CPC7695BC and CPC7695BCTR) represents the current active product line from IXYS Integrated Circuits Division for line card access switch applications, offering equivalent electrical performance with enhanced packaging options.
