Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX407CPA is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Dual operational amplifier configuration (2 circuits minimum)
• Rail-to-rail output capability
• 8-DIP through-hole package format (0.300", 7.62mm)
• Supply voltage range compatibility with 2.5V minimum and 10V maximum operation
• General-purpose amplifier classification

Substitute Parts Identified:

1. MAX407CPA+ — Direct equivalent with identical electrical specifications. Differs only in packaging format (Tube vs. unspecified for original) and product status (Active vs. Obsolete). All electrical parameters match exactly.

2. LMC6442IN/NOPB — Functionally compatible substitute. Maintains dual rail-to-rail configuration in 8-DIP package. Supply voltage range (1.8V to 11V) encompasses the MAX407CPA operating window. Electrical parameters remain within acceptable substitution tolerance for general-purpose applications.

3. TLV2242IP — Functionally compatible substitute. Maintains dual rail-to-rail configuration in 8-DIP package. Supply voltage range (2.5V to 12V) encompasses the MAX407CPA operating window. Electrical parameters remain within acceptable substitution tolerance for general-purpose applications.

Engineering Selection Recommendations

MAX407CPA+ (Direct Equivalent)

The MAX407CPA+ is the primary recommended substitute. It maintains identical electrical specifications and package format while offering active product status from the original manufacturer. This part is ROHS3 compliant, addressing regulatory requirements that the original MAX407CPA does not meet. Selection of MAX407CPA+ eliminates design re-qualification requirements and ensures continuity with the original component family.

LMC6442IN/NOPB (Functional Substitute)

The LMC6442IN/NOPB is suitable for applications where extended operating temperature range (-40°C to 85°C) is required beyond the MAX407CPA specification (0°C to 70°C). This part maintains the dual rail-to-rail configuration and 8-DIP package. The supply voltage range (1.8V to 11V) encompasses the MAX407CPA operating window. Input bias current is significantly lower (0.005 pA vs. 0.1 pA), which may improve performance in high-impedance signal paths.

TLV2242IP (Functional Substitute)

The TLV2242IP is suitable for applications requiring extended operating temperature range (-40°C to 125°C). This part maintains the dual rail-to-rail configuration and 8-DIP package. The supply voltage range (2.5V to 12V) encompasses the MAX407CPA operating window. Input offset voltage is lower (0.6 mV vs. 1 mV), which may improve precision in low-level signal applications.

Frequently Asked Questions (FAQ)

Q: Can MAX407CPA+ be used as a direct replacement for MAX407CPA?

A: Yes. The MAX407CPA+ is electrically identical to the MAX407CPA across all specified parameters. Both devices feature identical slew rate (0.005 V/µs), gain bandwidth product (8 kHz), input bias current (0.1 pA), and output current per channel (600 µA). The primary difference is product status (Active vs. Obsolete) and RoHS compliance (ROHS3 Compliant vs. RoHS non-compliant). Pinout and package dimensions are identical.

Q: What are the key differences between LMC6442IN/NOPB and the MAX407CPA?

A: The LMC6442IN/NOPB maintains functional equivalence through dual rail-to-rail configuration in 8-DIP package and compatible supply voltage range. Electrical differences include lower input bias current (0.005 pA vs. 0.1 pA), slightly higher input offset voltage (1.5 mV vs. 1 mV), higher supply current (1.9 µA vs. 1 µA), and significantly higher output current per channel (2.1 mA vs. 600 µA). Operating temperature range extends to -40°C to 85°C.

Q: What are the key differences between TLV2242IP and the MAX407CPA?

A: The TLV2242IP maintains functional equivalence through dual rail-to-rail configuration in 8-DIP package and compatible supply voltage range. Electrical differences include higher input bias current (100 pA vs. 0.1 pA), lower input offset voltage (0.6 mV vs. 1 mV), identical supply current (1 µA), and lower output current per channel (200 µA vs. 600 µA). Operating temperature range extends to -40°C to 125°C.

Q: Are all substitute parts available in 8-DIP through-hole package?

A: Yes. All identified substitute parts (MAX407CPA+, LMC6442IN/NOPB, and TLV2242IP) are available in 8-DIP through-hole package with 0.300" (7.62mm) spacing. This ensures mechanical compatibility with existing PCB layouts designed for the MAX407CPA.

Q: Which substitute part should be selected for low-temperature operation?

A: The MAX407CPA and MAX407CPA+ both specify 0°C minimum operating temperature. For applications requiring operation below 0°C, both LMC6442IN/NOPB (-40°C minimum) and TLV2242IP (-40°C minimum) extend the lower temperature limit. Selection between these two depends on specific electrical parameter requirements for the application.

Q: Which substitute part should be selected for high-temperature operation?

A: The MAX407CPA specifies 70°C maximum operating temperature. For applications requiring operation above 70°C, the LMC6442IN/NOPB extends to 85°C and the TLV2242IP extends to 125°C. Selection between these two depends on specific electrical parameter requirements and the maximum temperature threshold of the application.

Q: Are there RoHS compliance differences between the substitute parts?

A: The MAX407CPA is RoHS non-compliant. The MAX407CPA+ is ROHS3 compliant. RoHS compliance status for LMC6442IN/NOPB and TLV2242IP is not specified in the provided data. For applications requiring RoHS compliance, MAX407CPA+ is the recommended selection.

Q: Can these parts be used interchangeably in all applications?

A: Substitution depends on application-specific requirements. All parts maintain dual rail-to-rail configuration in 8-DIP package. Electrical parameter differences (slew rate, gain bandwidth product, input bias current, output current, and operating temperature range) must be evaluated against application specifications before substitution.
