Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX400CPA+ is determined by strict alignment of electrical and mechanical parameters. The critical substitution criteria are:

Mandatory Compatibility Parameters:

• Package type: 8-DIP (0.300", 7.62mm) through-hole configuration
• Number of circuits: 1 operational amplifier
• Supply voltage range: Minimum 6V, maximum 36V
• Operating temperature range: 0°C to 70°C or extended range
• Amplifier classification: General Purpose

Performance Parameters Defining Substitution Groups:

• Slew rate: 0.3V/µs (low-speed group) or higher performance variants
• Gain bandwidth product: 600 kHz (baseline) to higher bandwidth options
• Input bias current: 700 pA to nanoampere-level specifications
• Input offset voltage: 10 µV baseline with tighter tolerances available
• RoHS3 compliance and MSL rating: 1 (Unlimited)

Substitute parts are grouped into two categories: direct electrical equivalents maintaining the 0.3V/µs slew rate and 600 kHz bandwidth, and higher-performance alternatives offering enhanced specifications while maintaining package and supply voltage compatibility.

Parameter Comparison

Engineering Selection Recommendations

Direct Electrical Equivalents (Recommended for Drop-In Replacement):

The OP07EPZ and OP07CPZ maintain identical slew rate (0.3V/µs) and gain bandwidth product (600 kHz) specifications as the MAX400CPA+. Both devices are manufactured by Analog Devices and are in active production status. OP07EPZ is the closest match for the 0°C to 70°C operating temperature range, while OP07CPZ extends the temperature range to -40°C to 85°C. Both are ROHS3 compliant with MSL rating of 1 (Unlimited).

The OPA177GP from Texas Instruments provides equivalent performance with 0.3V/µs slew rate and 600 kHz bandwidth. This device features lower input bias current (500 pA) compared to the MAX400CPA+ (700 pA) and offers extended temperature range (-40°C to 85°C). OPA177GP is classified as Last Time Buy, indicating limited future availability.

Higher-Performance Alternatives (For Enhanced Specifications):

The OP27EPZ and OP27GPZ offer significantly improved slew rate (2.8V/µs) and gain bandwidth product (8 MHz) while maintaining the same supply voltage range and 8-DIP package. These devices are suitable for applications requiring faster signal processing. OP27EPZ operates within the 0°C to 70°C range, while OP27GPZ extends to -40°C to 85°C. Both are in active production.

The OPA277P provides intermediate performance with 0.8V/µs slew rate and 1 MHz bandwidth. This device operates from a lower minimum supply voltage (4V) and is suitable for battery-powered or low-voltage applications. OPA277P is classified as Last Time Buy.

High-Speed Alternatives (For Demanding Applications):

The AD847JNZ and AD848JNZ are high-speed operational amplifiers with slew rates of 300V/µs and gain bandwidth products of 50 MHz and 175 MHz respectively. These devices require a minimum supply voltage of 9V and are suitable only for applications where the MAX400CPA+ performance envelope is insufficient. Both are in active production status.

Compliance and Availability Considerations:

All recommended substitute parts maintain ROHS3 compliance and MSL rating of 1 (Unlimited), ensuring compatibility with modern manufacturing and environmental standards. Parts in active production status (OP07EPZ, OP07CPZ, OP27EPZ, OP27GPZ, AD847JNZ, AD848JNZ) are preferred for new designs. Parts with Last Time Buy status (OPA177GP, OPA277P) should be evaluated for long-term supply chain risk.

Frequently Asked Questions (FAQ)

Q: Can OP07EPZ directly replace MAX400CPA+ without circuit modification?

A: Yes. OP07EPZ maintains identical slew rate (0.3V/µs), gain bandwidth product (600 kHz), supply voltage range (6V to 36V), and 8-DIP package configuration. The primary difference is input bias current (1.2 nA versus 700 pA) and input offset voltage (30 µV versus 10 µV), which are acceptable for most general-purpose applications. Pin-to-pin compatibility is confirmed.

Q: What is the difference between OP27EPZ and OP07EPZ?

A: OP27EPZ provides higher performance with 2.8V/µs slew rate and 8 MHz gain bandwidth product compared to OP07EPZ at 0.3V/µs and 600 kHz. OP27EPZ requires a minimum supply voltage of 8V (versus 6V for OP07EPZ). Selection depends on application bandwidth requirements and available supply voltage.

Q: Why is the minimum supply voltage different for AD847JNZ and AD848JNZ?

A: AD847JNZ and AD848JNZ are high-speed operational amplifiers designed for different application classes. The 9V minimum supply requirement reflects their internal circuit architecture optimized for high slew rate (300V/µs) and high gain bandwidth product (50 MHz and 175 MHz respectively). These devices are not suitable for 6V supply applications.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed maintain ROHS3 compliance and MSL rating of 1 (Unlimited), ensuring compatibility with current manufacturing standards and environmental regulations.

Q: What is the significance of "Last Time Buy" status for OPA177GP and OPA277P?

A: Last Time Buy status indicates that the manufacturer has announced end-of-life for these products. While currently available, future supply cannot be guaranteed. For new designs requiring long-term component availability, preference should be given to parts with Active status.

Q: Can I use AD848JNZ in a circuit designed for MAX400CPA+?

A: AD848JNZ is not recommended as a direct substitute. While both are 8-DIP general-purpose operational amplifiers, AD848JNZ requires a minimum supply voltage of 9V (versus 6V for MAX400CPA+) and exhibits significantly different electrical characteristics (300V/µs slew rate, 175 MHz bandwidth, 3.3 µA input bias current). Circuit redesign would be necessary.

Q: What is the operating temperature range difference between OP07EPZ and OP07CPZ?

A: OP07EPZ operates from 0°C to 70°C, matching the MAX400CPA+ temperature range. OP07CPZ extends the range to -40°C to 85°C, providing wider environmental tolerance. Selection depends on application temperature requirements.

Q: Are the 8-DIP packages for all substitute parts mechanically identical?

A: Yes. All substitute parts use 8-DIP (0.300", 7.62mm) through-hole packages with identical mechanical dimensions and pin configurations, ensuring direct PCB compatibility without layout modifications.
