CPC7591BBTR Equivalent & Substitute Parts

Part Overview

The CPC7591BBTR is a telecom interface IC designed for line card access switch applications in telecommunications equipment. Manufactured by IXYS Integrated Circuits Division, this component operates within a 4.5V to 5.5V supply range and is housed in a 16-SOIC package. The part is currently classified as obsolete, making identification of suitable substitutes essential for legacy system maintenance and component procurement planning.

Key Parameters

Substitute Part Grouping Explanation

The CPC7695BCTR is identified as a manufacturer-recommended substitute for the CPC7591BBTR. Substitution eligibility is determined by the following critical parameters:

• Identical voltage supply range (4.5V ~ 5.5V)
• Identical current supply specification (2mA)
• Identical power consumption (10.5 mW)
• Identical operating temperature range (-40°C ~ 110°C)
• Identical mounting type (Surface Mount)
• Identical moisture sensitivity level (MSL 1 - Unlimited)
• Identical functional classification (Line Card Access Switch)
• Identical manufacturer (IXYS Integrated Circuits Division)

The primary difference between these parts is the package configuration: the CPC7591BBTR uses a 16-SOIC package, while the CPC7695BCTR uses a 28-SOIC package. Both packages maintain the same 0.295" width and 7.50mm standard dimensions, allowing for PCB layout adaptation where pin count requirements permit.

Parameter Comparison

Engineering Selection Recommendations

The CPC7695BCTR is the manufacturer-recommended substitute for the CPC7591BBTR. Selection of this substitute is supported by the following factors:

• All critical electrical parameters (voltage, current, power, temperature range) are identical between the two parts
• Both components are manufactured by IXYS Integrated Circuits Division, ensuring consistent design and quality standards
• The CPC7695BCTR maintains active product status, ensuring ongoing availability and supply chain reliability
• The CPC7695BCTR is ROHS3 compliant, meeting current environmental and regulatory requirements
• Both parts share identical moisture sensitivity classification and handling requirements

The primary consideration for implementation is the package transition from 16-SOIC to 28-SOIC. This change requires PCB layout modification to accommodate the additional pin count and package footprint. The identical package width (0.295", 7.50mm) facilitates this transition within standard manufacturing tolerances.

Frequently Asked Questions (FAQ)

Q: Can the CPC7695BCTR directly replace the CPC7591BBTR without circuit modification?

A: The CPC7695BCTR is electrically equivalent to the CPC7591BBTR across all specified parameters. However, the package change from 16-SOIC to 28-SOIC requires PCB layout modification. Direct socket replacement is not possible without redesign.

Q: What is the significance of the package change from 16-SOIC to 28-SOIC?

A: The 28-SOIC package provides additional pins compared to the 16-SOIC package. Both packages maintain identical width specifications (0.295", 7.50mm), but the pin count increase requires corresponding PCB footprint changes and potential circuit routing adjustments.

Q: Are there compliance differences between these parts?

A: The CPC7695BCTR is ROHS3 compliant, while the CPC7591BBTR does not specify RoHS status. Both parts are REACH unaffected and carry identical ECCN and HTSUS classifications.

Q: Why is the CPC7591BBTR classified as obsolete?

A: The CPC7591BBTR is no longer in active production. The CPC7695BCTR represents the current active alternative from the manufacturer for line card access switch applications.

Q: What is the TTL interface specification on the CPC7695BCTR?

A: The CPC7695BCTR specifies TTL interface compatibility. This parameter is not documented for the CPC7591BBTR in the provided specifications.

Q: Are moisture handling requirements identical for both parts?

A: Yes. Both the CPC7591BBTR and CPC7695BCTR carry MSL 1 (Unlimited) classification, indicating identical moisture sensitivity and storage requirements.
