MAX419CPD+ Equivalent & Substitute Parts

Part Overview

The MAX419CPD+ is a general purpose operational amplifier featuring four independent circuits in a 14-DIP through-hole package. Manufactured by Analog Devices Inc./Maxim Integrated, this device provides rail-to-rail output capability with a supply voltage range of 2.5V to 10V and operates across 0°C to 70°C. The MAX419CPD+ is classified as obsolete, necessitating identification of active equivalent components for new designs and ongoing production requirements. Substitute parts must maintain functional compatibility through matching package type, circuit count, output configuration, and electrical operating parameters.

Substitute Part Grouping Explanation

Substitution of the MAX419CPD+ is determined by strict adherence to the following criteria:

Mandatory Matching Parameters:

• Amplifier Type: General Purpose
• Number of Circuits: 4
• Output Type: Rail-to-Rail
• Package / Case: 14-DIP (0.300", 7.62mm)
• Mounting Type: Through Hole
• Supplier Device Package: 14-PDIP

Allowable Parameter Ranges for Substitution:

• Voltage - Supply Span (Min): 2.5V or lower
• Voltage - Supply Span (Max): 10V or higher
• Operating Temperature: Must encompass or exceed 0°C to 70°C range
• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected

The substitute parts identified—OP491GPZ and TL974IN—satisfy all mandatory matching parameters and operate within allowable electrical ranges. Both are active products with current manufacturing status, addressing the obsolescence of the MAX419CPD+.

Parameter Comparison

Engineering Selection Recommendations

OP491GPZ Selection Criteria: The OP491GPZ is an active product from Analog Devices Inc. with ROHS3 compliance and REACH unaffected status. It maintains the same manufacturer lineage as the MAX419CPD+ and provides enhanced performance specifications including 0.5V/µs slew rate and 3MHz gain bandwidth product. The extended operating temperature range (-40°C to 125°C) exceeds the original specification. Supply voltage range of 2.7V to 12V encompasses the MAX419CPD+ operating window. This substitute is suitable for applications where the original performance envelope is acceptable and manufacturer continuity is preferred.

TL974IN Selection Criteria: The TL974IN is an active product from Texas Instruments with ROHS3 compliance and REACH unaffected status. It delivers significantly enhanced performance with 5V/µs slew rate and 12MHz gain bandwidth product. The extended operating temperature range (-40°C to 125°C) and supply voltage range (2.7V to 12V) provide broader operational flexibility. This substitute is suitable for applications requiring higher speed performance and extended environmental operating conditions.

Both substitutes satisfy mandatory compliance requirements and package compatibility. Selection between OP491GPZ and TL974IN depends on application-specific performance requirements and supply chain considerations.

Frequently Asked Questions (FAQ)

Q: Can OP491GPZ or TL974IN be used as direct pin-for-pin replacements for MAX419CPD+?

A: Yes. Both substitute parts share identical 14-DIP package configuration with 0.300" (7.62mm) pitch. Pin assignments for four general purpose rail-to-rail amplifier circuits are compatible. Through-hole mounting type is identical. Direct socket substitution is mechanically and electrically feasible.

Q: What are the key performance differences between the three parts?

A: The MAX419CPD+ operates at 0.08V/µs slew rate with 150kHz gain bandwidth product. OP491GPZ provides 0.5V/µs slew rate and 3MHz bandwidth. TL974IN delivers 5V/µs slew rate and 12MHz bandwidth. Supply current consumption increases from 1µA (MAX419CPD+) to 260µA (OP491GPZ) to 2mA (TL974IN). Output current capability ranges from 600µA to 16mA to 80mA respectively. Selection depends on application bandwidth and power budget requirements.

Q: Are there temperature range limitations when substituting?

A: The MAX419CPD+ operates 0°C to 70°C. OP491GPZ and TL974IN both operate -40°C to 125°C. If the application requires operation only within 0°C to 70°C, both substitutes are suitable. If operation below 0°C or above 70°C is required, both substitutes provide extended capability. No temperature-based limitation exists for substitution within the original operating range.

Q: What is the supply voltage compatibility?

A: MAX419CPD+ operates 2.5V to 10V. OP491GPZ operates 2.7V to 12V. TL974IN operates 2.7V to 12V. Both substitutes accommodate the original 2.5V to 10V range. If operation at 2.5V minimum is critical, verify OP491GPZ and TL974IN performance at this voltage level, as their specified minimum is 2.7V.

Q: Are compliance certifications identical across all three parts?

A: All three parts are ROHS3 compliant and REACH unaffected. Moisture Sensitivity Level (MSL) is 1 (Unlimited) for MAX419CPD+ and OP491GPZ. TL974IN lists MSL as Not Applicable. All parts carry ECCN EAR99 and HTSUS 8542.33.0001 classifications. Compliance status is equivalent for regulatory purposes.

Q: Which substitute should be selected for new designs?

A: Selection between OP491GPZ and TL974IN depends on application requirements. OP491GPZ maintains Analog Devices manufacturer continuity with moderate performance enhancement. TL974IN provides maximum performance enhancement with higher slew rate and bandwidth. Both are active products with established supply chains. Evaluate specific application bandwidth, power consumption, and output current requirements to determine optimal selection.
