MAX417CPA+ Equivalent & Substitute Parts

Part Overview

The MAX417CPA+ is a general-purpose operational amplifier manufactured by Analog Devices Inc./Maxim Integrated, featuring two independent circuits in an 8-PDIP through-hole package. This device is classified as obsolete, making identification of functionally equivalent substitutes essential for ongoing system support and component procurement.

The MAX417CPA+ is designed for applications requiring rail-to-rail output capability with low input bias current and moderate bandwidth performance. Due to its obsolete status, alternative components with compatible electrical and mechanical specifications are necessary to maintain design continuity and ensure long-term component availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX417CPA+ is determined by the following critical parameters:

Mechanical Compatibility:

• Package type: 8-DIP (0.300", 7.62mm)
• Mounting type: Through Hole
• Pin count and spacing must match for direct board-level replacement

Electrical Compatibility:

• Number of circuits: 2 independent amplifier channels
• Output type: Rail-to-Rail capability
• Supply voltage range: Must accommodate the 2.5 V to 10 V operating span
• Input offset voltage: 1 mV specification
• Package classification: 8-PDIP

Regulatory Compliance:

• RoHS3 compliance required
• Moisture Sensitivity Level 1 (Unlimited)

The LMC6042AIN/NOPB from Texas Instruments satisfies all mechanical and regulatory requirements. This substitute maintains the 8-DIP package format, through-hole mounting, and RoHS3 compliance. Both devices feature dual-channel rail-to-rail output amplifiers in identical physical packages, enabling direct substitution at the board level.

Parameter Comparison

Engineering Selection Recommendations

Substitution Feasibility:

The LMC6042AIN/NOPB is a direct mechanical and electrical substitute for the MAX417CPA+. Both devices share identical 8-DIP package geometry, through-hole mounting configuration, and pin assignments, enabling board-level replacement without layout modifications.

Compliance Status:

Both the MAX417CPA+ and LMC6042AIN/NOPB maintain ROHS3 compliance and Moisture Sensitivity Level 1 (Unlimited) classification, satisfying regulatory requirements for equivalent component substitution.

Product Lifecycle Considerations:

The MAX417CPA+ is classified as obsolete, while the LMC6042AIN/NOPB carries a Last Time Buy status. This distinction indicates that the LMC6042AIN/NOPB remains available through current distribution channels with defined procurement windows, whereas the MAX417CPA+ has reached end-of-life status.

Electrical Performance Differences:

The LMC6042AIN/NOPB exhibits lower input bias current (0.002 pA versus 0.1 pA) and reduced slew rate (0.02 V/µs versus 0.08 V/µs). The substitute device operates across an extended temperature range (-40°C to 85°C versus 0°C to 70°C) and supports higher maximum supply voltage (15.5 V versus 10 V). These differences reflect the CMOS architecture of the LMC6042AIN/NOPB compared to the general-purpose design of the MAX417CPA+.

Frequently Asked Questions (FAQ)

Q: Can the LMC6042AIN/NOPB be used as a direct replacement for the MAX417CPA+ without circuit modifications?

A: Yes. Both devices feature identical 8-DIP package dimensions, through-hole mounting, and dual-channel rail-to-rail amplifier configurations. Direct board-level substitution is supported without layout changes.

Q: What are the key electrical differences between these devices?

A: The LMC6042AIN/NOPB features lower input bias current (0.002 pA), reduced slew rate (0.02 V/µs), and higher output current capability per channel (40 mA versus 600 µA). The substitute operates across a wider temperature range and supports higher supply voltages.

Q: Are both devices RoHS3 compliant?

A: Yes. Both the MAX417CPA+ and LMC6042AIN/NOPB are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited) classification.

Q: What is the significance of the product status difference?

A: The MAX417CPA+ is obsolete and no longer manufactured. The LMC6042AIN/NOPB carries Last Time Buy status, indicating limited future availability through defined procurement windows. For new designs or long-term support, the LMC6042AIN/NOPB is the appropriate selection.

Q: Does the lower slew rate of the LMC6042AIN/NOPB affect circuit performance?

A: Slew rate differences affect the maximum rate of output voltage change. Applications requiring high-speed transient response may require circuit evaluation. The 0.02 V/µs slew rate of the LMC6042AIN/NOPB is lower than the MAX417CPA+ specification of 0.08 V/µs.

Q: What is the minimum supply voltage requirement for the LMC6042AIN/NOPB?

A: The LMC6042AIN/NOPB requires a minimum supply voltage of 4.5 V, compared to 2.5 V for the MAX417CPA+. Circuits designed for operation below 4.5 V require design modification or alternative component selection.
