Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ICL7642ECPD is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Amplifier type: CMOS
• Number of circuits: 4 independent channels
• Output configuration: Rail-to-rail
• Slew rate: 1.6 V/µs
• Gain bandwidth product: 1.4 MHz
• Input bias current: 1 pA
• Input offset voltage: 20 mV
• Supply current per channel: 1 mA
• Supply voltage range: 2 V to 16 V
• Operating temperature: 0°C to 70°C

Mechanical Equivalence Criteria:

• Package type: 14-DIP (0.300", 7.62mm)
• Mounting method: Through Hole
• Supplier device package: 14-PDIP

Parts meeting all electrical and mechanical parameters are classified as direct substitutes. Variations in product status, packaging format (tube vs. bulk), or compliance certifications do not affect functional substitutability.

Parameter Comparison

Engineering Selection Recommendations

ICL7642ECPD+ as Primary Substitute:

The ICL7642ECPD+ is a direct functional equivalent to the ICL7642ECPD. All electrical parameters, mechanical specifications, and pin configurations are identical. The substitute part is manufactured by the same supplier (Analog Devices Inc./Maxim Integrated) and maintains the same base product number (ICL7642).

Compliance Advantages:

The ICL7642ECPD+ carries active product status and ROHS3 compliance certification, whereas the original ICL7642ECPD is obsolete and RoHS non-compliant. For new designs or production runs subject to environmental regulations, the ICL7642ECPD+ is the appropriate selection.

Inventory Considerations:

The ICL7642ECPD+ is available in higher inventory quantities (5671 pieces) compared to the original part (1477 pieces), supporting sustained production requirements and reducing supply chain risk.

Packaging Format:

The ICL7642ECPD+ is supplied in tube packaging, which is standard for through-hole components and compatible with automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can ICL7642ECPD+ be used as a direct replacement for ICL7642ECPD in existing designs?

A: Yes. The ICL7642ECPD+ is electrically and mechanically equivalent. All electrical parameters, pin assignments, and package dimensions are identical. No circuit modifications are required.

Q: What is the difference between ICL7642ECPD and ICL7642ECPD+?

A: The primary differences are product status and compliance certification. The ICL7642ECPD is obsolete and RoHS non-compliant. The ICL7642ECPD+ is active and ROHS3 compliant. Electrical and mechanical specifications are identical.

Q: Does the RoHS3 compliance of ICL7642ECPD+ affect circuit performance?

A: No. RoHS3 compliance relates to material composition and environmental standards, not electrical performance. The ICL7642ECPD+ maintains identical electrical characteristics to the original part.

Q: Are there any thermal or reliability differences between these parts?

A: No differences are specified in the provided parameters. Both parts operate across the same temperature range (0°C to 70°C) and share identical electrical specifications.

Q: What is the significance of the "+" suffix in ICL7642ECPD+?

A: The "+" suffix indicates a variant of the base product (ICL7642). In this case, it denotes the active, RoHS-compliant version of the component.

Q: Can ICL7642ECPD be used in new production designs?

A: The ICL7642ECPD is classified as obsolete. For new designs, ICL7642ECPD+ is the recommended selection to ensure long-term availability and compliance with current environmental regulations.

Q: Is the 14-DIP through-hole package still suitable for modern assembly?

A: Yes. Through-hole packages remain standard for applications requiring manual rework capability, high-reliability requirements, or legacy system support. Both parts use identical 14-DIP packaging compatible with standard through-hole assembly equipment.
