Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: ICL7612DCBAZ

The ICL7612DCBAZ (Renesas Electronics Corporation) is the preferred substitute for the obsolete ICL7612BESA. This part maintains electrical equivalence across all critical parameters including slew rate, gain bandwidth product, input bias current, and supply voltage range. The ICL7612DCBAZ carries Active product status, ensuring long-term availability and supply chain stability. RoHS3 compliance satisfies modern regulatory requirements. Inventory availability of 15,550 units provides immediate procurement capability.

Secondary Recommendation: ICL7612DCBAZ-T

The ICL7612DCBAZ-T offers identical electrical specifications to the ICL7612DCBAZ with Tape & Reel (TR) packaging format. This configuration is suitable for high-volume automated assembly operations. RoHS3 compliance and Active product status are maintained. Inventory of 3,188 units supports production requirements.

Alternative Recommendation: ICL7612BESA+

The ICL7612BESA+ (Analog Devices Inc./Maxim Integrated) provides direct electrical equivalence to the original ICL7612BESA, including identical input offset voltage specification of 5 mV. This part maintains the original manufacturer lineage and carries Active product status with RoHS3 compliance. Tube packaging is provided. Inventory of 855 units is available.

Consideration: ICL7611 Series Parts

The ICL7611DCBAZ and ICL7611DCBAZ-T represent functionally equivalent alternatives based on the ICL7611 base design. These parts maintain electrical compatibility across core parameters (slew rate, gain bandwidth product, input bias current, supply voltage range) and are available in Active status with RoHS3 compliance. Operating temperature range is restricted to 0°C to 70°C compared to the original -40°C to 85°C specification. Selection of ICL7611 variants requires confirmation that the narrower temperature range is acceptable for the target application.

Compliance Considerations:

All recommended substitute parts carry RoHS3 compliance status, addressing regulatory requirements for hazardous substance restrictions. The original ICL7612BESA is RoHS non-compliant. Migration to RoHS3-compliant alternatives is necessary for applications subject to RoHS directives. All parts maintain REACH Unaffected status and MSL Level 1 (Unlimited) moisture sensitivity classification.

Frequently Asked Questions (FAQ)

Q1: Can the ICL7612DCBAZ directly replace the ICL7612BESA in existing designs?

A: The ICL7612DCBAZ maintains electrical equivalence across all critical operational parameters: slew rate (1.6 V/µs), gain bandwidth product (1.4 MHz), input bias current (1 pA), supply voltage range (2V to 16V), and package configuration (8-SOIC surface mount). Direct substitution is supported from an electrical and mechanical standpoint. The primary design consideration is the operating temperature range: the ICL7612DCBAZ operates from 0°C to 70°C, whereas the original ICL7612BESA operates from -40°C to 85°C. Applications requiring operation below 0°C or above 70°C require design review.

Q2: 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, suitable for manual assembly and lower-volume production. ICL7612DCBAZ-T is supplied in Tape & Reel (TR) format, optimized for automated pick-and-place assembly equipment and high-volume manufacturing. Selection depends on assembly process requirements and production volume.

Q3: Why does the ICL7612BESA+ show different input offset voltage (5 mV) compared to the Renesas ICL7612DCBAZ (15 mV)?

A: Input offset voltage is a specified electrical parameter that varies between manufacturer implementations. The ICL7612BESA+ maintains the original Analog Devices specification of 5 mV maximum input offset voltage. The Renesas ICL7612DCBAZ specifies 15 mV maximum input offset voltage. For applications with tight offset voltage requirements, the ICL7612BESA+ provides closer specification alignment to the original part. For applications where 15 mV offset is acceptable, the ICL7612DCBAZ is suitable.

Q4: Are the ICL7611DCBAZ and ICL7611DCBAZ-T suitable substitutes?

A: The ICL7611 series parts maintain electrical equivalence across core amplifier parameters (slew rate, gain bandwidth product, input bias current, supply voltage range) and are mechanically compatible (8-SOIC package, surface mount). However, the operating temperature range is narrower: 0°C to 70°C versus the original -40°C to 85°C. The ICL7611 variants are suitable substitutes only for applications that do not require operation below 0°C or above 70°C. Applications with extended temperature requirements must use ICL7612 series parts.

Q5: What is the significance of RoHS3 compliance for substitute part selection?

A: RoHS3 compliance indicates that the part meets Restriction of Hazardous Substances (RoHS) directives, restricting the use of specific hazardous materials including lead, cadmium, mercury, and certain flame retardants. The original ICL7612BESA is RoHS non-compliant. All recommended substitute parts (ICL7612BESA+, ICL7612DCBAZ, ICL7612DCBAZ-T, ICL7611DCBAZ, ICL7611DCBAZ-T) are RoHS3 compliant. For applications subject to RoHS regulations or customer requirements, RoHS3-compliant substitutes are mandatory.

Q6: What inventory levels are available for each substitute part?

A: Current inventory levels are: ICL7612DCBAZ (15,550 pcs), ICL7612DCBAZ-T (3,188 pcs), ICL7611DCBAZ-T (2,092 pcs), ICL7611DCBAZ (1,300 pcs), and ICL7612BESA+ (855 pcs). The ICL7612DCBAZ offers the highest inventory availability, supporting immediate procurement for production requirements.

Q7: Is the 8-SOIC package footprint identical across all substitute parts?

A: All substitute parts use the 8-SOIC package with identical dimensions: 0.154" width, 3.90mm width specification. PCB footprints and land patterns are mechanically compatible across all listed substitutes. No PCB redesign is required for package compatibility.

Q8: What is the significance of MSL Level 1 (Unlimited) moisture sensitivity?

A: Moisture Sensitivity Level (MSL) 1 (Unlimited) indicates that the component has no moisture sensitivity restrictions. These parts do not require special moisture-controlled storage, handling, or baking procedures prior to soldering. Standard storage and handling practices are applicable. This classification applies uniformly across all substitute parts listed.
