Engineering Selection Recommendations

TC7652CPD as Primary Substitute:

The TC7652CPD from Microchip Technology is the direct substitute for the obsolete ICL7652CPD. Selection of the TC7652CPD is supported by the following factors:

Product Status: The TC7652CPD maintains active product status with Microchip Technology, ensuring long-term availability and continued manufacturing support. The ICL7652CPD is obsolete, making the TC7652CPD the appropriate choice for new designs and ongoing production requirements.

Regulatory Compliance: Both devices maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for applications in regulated industries and markets requiring these certifications.

Package and Mechanical Compatibility: Identical 14-DIP package specifications and through-hole mounting type ensure direct physical compatibility with existing PCB layouts and assembly processes without requiring design modifications.

Electrical Operating Range: Both devices operate across the identical 5V to 16V supply voltage range and 0°C to 70°C temperature range, ensuring functional compatibility in existing system designs.

Performance Characteristics: While the TC7652CPD exhibits different performance specifications in slew rate, gain bandwidth product, input bias current, and input offset voltage compared to the ICL7652CPD, these differences remain within the operational envelope of zero-drift amplifier technology and do not preclude functional substitution in applications designed for the ICL7652CPD.

Frequently Asked Questions (FAQ)

Q: Can the TC7652CPD be used as a direct replacement for the ICL7652CPD without PCB modifications?
