CPC7692BB Equivalent & Substitute Parts

Part Overview

The CPC7692BB is a telecom interface integrated circuit 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 is classified as an obsolete product. Due to its obsolete status, equivalent substitute parts are necessary for ongoing system maintenance, redesigns, and new production applications requiring compatible functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CPC7692BB is determined by the following critical parameters that must remain compatible:

Mandatory Compatibility Parameters:

• Voltage Supply Range: 4.5V ~ 5.5V
• Mounting Type: Surface Mount
• Function: Line Card Access Switch
• Manufacturer: IXYS Integrated Circuits Division
• RoHS Compliance: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The substitute parts CPC7695BC and CPC7695BCTR maintain identical supply voltage specifications, current draw, power consumption, and thermal operating characteristics. Both substitutes are manufactured by the same supplier and share the same functional classification as telecom interface Line Card Access Switch components. The primary difference lies in the package configuration (28-SOIC versus 16-SOIC) and product status (Active versus Obsolete), with substitute parts offering extended operating temperature ranges and active product support.

Parameter Comparison

Engineering Selection Recommendations

CPC7695BC is suitable for applications requiring tube packaging and active product support. This part maintains full electrical compatibility with the CPC7692BB while offering an extended operating temperature range to 110°C and active product status from IXYS Integrated Circuits Division.

CPC7695BCTR is the preferred substitute for high-volume production and long-term supply chain requirements. This variant provides the same electrical specifications as CPC7695BC with significantly higher inventory availability (10,099 pieces in stock) and active product status. The extended temperature range (-40°C to 110°C) provides additional thermal margin compared to the original CPC7692BB specification.

Both substitute parts are ROHS3 compliant and REACH unaffected, maintaining regulatory compliance equivalent to the original component. The transition from 16-SOIC to 28-SOIC packaging requires PCB layout modification but does not affect electrical functionality within the specified voltage and current parameters.

Frequently Asked Questions (FAQ)

Q: Can CPC7695BC or CPC7695BCTR directly replace CPC7692BB without circuit modification?

A: Electrical substitution is valid based on identical supply voltage (4.5V ~ 5.5V), current draw (2mA), and power consumption specifications. However, the package change from 16-SOIC to 28-SOIC requires PCB layout redesign. Pin configuration differences necessitate schematic and layout verification before implementation.

Q: What is the significance of the extended operating temperature range in the substitute parts?

A: The substitute parts operate from -40°C to 110°C compared to the original -40°C to 85°C range. This extended specification provides additional thermal margin for applications operating in elevated ambient conditions or with higher component density on the PCB.

Q: Why is CPC7695BCTR recommended over CPC7695BC?

A: CPC7695BCTR offers superior supply chain continuity with 10,099 pieces in stock versus 724 pieces for CPC7695BC. Both parts are electrically identical and ROHS3 compliant. The higher inventory level of CPC7695BCTR reduces procurement risk for production applications.

Q: Are there differences in interface specifications between the main part and substitutes?

A: The CPC7692BB specifies Logic interface, while both substitute parts specify TTL interface. Both interface types operate within the same 4.5V to 5.5V supply voltage range and are compatible with standard digital logic circuits.

Q: What compliance certifications apply to all three parts?

A: All three parts are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited). The substitute parts carry EAR99 ECCN classification and HTSUS code 8542.39.0001, indicating standard commercial electronic component status.
