Key Parameters

Substitute Part Grouping Explanation

Substitution of the CPC7592BCTR is based on the following critical parameters that define functional and physical compatibility:

Voltage Supply Range: Both substitute parts maintain the identical 4.5V ~ 5.5V supply voltage specification, ensuring direct electrical compatibility.

Operating Temperature Range: The substitute parts operate across the same -40°C ~ 110°C temperature range, maintaining thermal performance requirements.

Manufacturer & Series: Both substitutes are manufactured by IXYS Integrated Circuits Division and belong to the same CPC769x telecom interface IC family, ensuring functional equivalence for line card access switch applications.

RoHS & Compliance: All parts maintain ROHS3 compliance and identical regulatory certifications (REACH Unaffected, EAR99, HTSUS 8542.39.0001), supporting equivalent environmental and export requirements.

Mounting Type & Interface: Surface mount configuration and TTL interface compatibility are preserved across substitute parts.

The primary difference between the main part and substitutes is the package configuration: the CPC7592BCTR uses a 16-SOIC package, while the substitute parts use a 28-SOIC package. This package change requires PCB layout modification but does not affect electrical functionality.

Parameter Comparison

Engineering Selection Recommendations

The CPC7695BC and CPC7695BCTR are manufacturer-recommended substitutes for the obsolete CPC7592BCTR. Both substitute parts are currently in active production status, ensuring long-term availability and supply chain stability.

CPC7695BCTR is the preferred substitute option, with significantly higher inventory availability (10,099 pieces in stock) compared to CPC7695BC (724 pieces in stock). Both parts maintain identical electrical specifications and regulatory compliance profiles.

The transition from 16-SOIC to 28-SOIC packaging requires PCB redesign. This package change does not impact electrical performance but necessitates layout modification and re-qualification of the updated assembly.

Power consumption increases marginally from 10 mW to 10.5 mW, which is negligible for most telecommunications applications and does not require thermal design changes.

Frequently Asked Questions (FAQ)

Q: Can CPC7695BC and CPC7695BCTR be used interchangeably?

A: Both parts are electrically equivalent and share identical specifications. The primary difference is packaging format: CPC7695BC is supplied in tube packaging, while CPC7695BCTR uses alternative packaging. Selection depends on procurement and assembly requirements.

Q: What is the impact of changing from 16-SOIC to 28-SOIC packaging?

A: The package footprint change requires PCB layout modification. The 28-SOIC package has a larger pin count and different pin configuration. Existing 16-SOIC PCB designs cannot accommodate the 28-SOIC package without redesign.

Q: Are the substitute parts compatible with existing 4.5V to 5.5V power supplies?

A: Yes. Both CPC7695BC and CPC7695BCTR operate within the identical 4.5V to 5.5V supply voltage range as the original CPC7592BCTR, ensuring direct power supply compatibility.

Q: Do the substitute parts maintain the same operating temperature range?

A: Yes. All parts operate across -40°C to 110°C, maintaining thermal performance requirements for telecommunications infrastructure applications.

Q: What is the significance of the TTL interface specification in the substitute parts?

A: The TTL interface designation in the substitute parts indicates signal compatibility with TTL-level logic circuits. This specification was not provided for the original CPC7592BCTR but represents the functional interface standard for this component family.

Q: Are there any compliance or regulatory differences between the parts?

A: No. All three parts maintain identical RoHS3 compliance, REACH unaffected status, EAR99 export classification, and HTSUS coding, ensuring equivalent regulatory and environmental compliance.
