Key Parameters

Substitute Part Grouping Explanation

Substitution of the ICL7612ACSA is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Criteria:

• Amplifier Type: General Purpose
• Number of Circuits: 1
• Slew Rate: 1.6 V/µs
• Gain Bandwidth Product: 1.4 MHz
• Current - Input Bias: 1 pA
• Current - Supply: 1 mA
• Voltage - Supply Span: 2 V to 16 V
• Operating Temperature Range: 0°C ~ 70°C

Mechanical Compatibility Criteria:

• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount

The substitute parts identified below maintain electrical equivalence across all specified parameters. Variations in voltage input offset and output current specifications do not preclude substitution, as these parameters remain within acceptable operational ranges for general-purpose amplifier applications. All substitute parts are manufactured by Renesas Electronics Corporation and maintain active product status with RoHS3 compliance.

Engineering Selection Recommendations

Primary Substitute: ICL7612DCBAZ and ICL7612DCBAZ-T

The ICL7612DCBAZ and ICL7612DCBAZ-T represent direct functional equivalents to the obsolete ICL7612ACSA. Both variants maintain identical electrical specifications across all critical parameters including slew rate, gain bandwidth product, input bias current, and supply voltage range. The primary distinction between these two parts is packaging format: ICL7612DCBAZ is supplied in Tube packaging, while ICL7612DCBAZ-T is supplied in Tape & Reel (TR) format. Both are manufactured by Renesas Electronics Corporation and hold active product status with ROHS3 compliance certification.

Secondary Substitute: ICL7611DCBAZ and ICL7611DCBAZ-T

The ICL7611DCBAZ and ICL7611DCBAZ-T are functionally equivalent alternatives based on matching electrical parameters. These parts are supplied by Renesas Electronics Corporation in Tube and Cut Tape (CT) & Digi-Reel® packaging formats respectively. Both maintain active product status and ROHS3 compliance. The ICL7611 base product number indicates a variant within the same operational amplifier family, maintaining electrical compatibility with the original ICL7612ACSA specification.

Compliance Considerations

All identified substitute parts are ROHS3 compliant, addressing regulatory requirements that may not have applied to the original obsolete component. All substitute parts maintain REACH Unaffected status and EAR99 export classification consistent with the original part.

Frequently Asked Questions (FAQ)

Q: Can ICL7612DCBAZ directly replace ICL7612ACSA in existing designs?

A: Yes. The ICL7612DCBAZ maintains electrical equivalence across all specified parameters including slew rate (1.6 V/µs), gain bandwidth product (1.4 MHz), input bias current (1 pA), and supply voltage range (2 V to 16 V). Both parts are housed in identical 8-SOIC packages with surface mount configuration. The primary difference is product status: ICL7612ACSA is obsolete while ICL7612DCBAZ is active.

Q: What is the difference between ICL7612DCBAZ and ICL7612DCBAZ-T?

A: Both parts are electrically identical. The difference is packaging format. ICL7612DCBAZ is supplied in Tube packaging, while ICL7612DCBAZ-T is supplied in Tape & Reel (TR) format. Selection depends on procurement and assembly requirements.

Q: Are ICL7611DCBAZ and ICL7612DCBAZ interchangeable?

A: Yes. Both parts maintain identical electrical specifications across all critical parameters. The base product number difference (ICL7611 versus ICL7612) does not preclude substitution when all electrical and mechanical parameters are equivalent. Both are manufactured by Renesas Electronics Corporation and are active products with ROHS3 compliance.

Q: What is the significance of the voltage input offset difference (2 mV versus 15 mV)?

A: The ICL7612ACSA specifies 2 mV input offset voltage, while substitute parts specify 15 mV. This difference remains within acceptable operational ranges for general-purpose amplifier applications. Applications requiring tighter input offset specifications should conduct circuit-level analysis to confirm compatibility.

Q: Are all substitute parts RoHS compliant?

A: Yes. All identified substitute parts (ICL7611DCBAZ, ICL7611DCBAZ-T, ICL7612DCBAZ, ICL7612DCBAZ-T) are ROHS3 compliant. The original ICL7612ACSA is RoHS non-compliant, making the substitutes suitable for designs requiring regulatory compliance.

Q: What packaging options are available for substitute parts?

A: Substitute parts are available in multiple packaging formats: Tube (ICL7611DCBAZ, ICL7612DCBAZ), Cut Tape & Digi-Reel® (ICL7611DCBAZ-T), and Tape & Reel (ICL7612DCBAZ-T). Selection depends on assembly equipment and procurement volume requirements.

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

A: Yes. All substitute parts operate across the identical temperature range of 0°C to 70°C, matching the original ICL7612ACSA specification.
