MAX907CPA Equivalent & Substitute Parts

Part Overview

The MAX907CPA is a general-purpose dual comparator IC manufactured by Analog Devices Inc./Maxim Integrated, housed in an 8-DIP through-hole package. This device is classified as obsolete, which necessitates identification of functionally equivalent alternatives for new designs or component replenishment. The MAX907CPA operates across a 4.5V to 11V supply range with TTL output configuration, making it suitable for precision voltage comparison applications in legacy systems and retrofit scenarios.

Substitute Part Grouping Explanation

Substitution of the MAX907CPA is determined by strict equivalence across the following critical parameters:

• Number of Elements: 2 comparators
• Output Type: TTL
• Voltage - Supply, Single/Dual (±): 4.5V ~ 11V
• Voltage - Input Offset (Max): 2mV @ 5V
• Current - Input Bias (Max): 0.3µA @ 5V
• Current - Quiescent (Max): 1mA
• CMRR, PSRR (Typ): 86.02dB CMRR, 86.02dB PSRR
• Propagation Delay (Max): 50ns
• Operating Temperature: 0°C ~ 70°C
• Package / Case: 8-DIP (0.300", 7.62mm)
• Mounting Type: Through Hole

The MAX907CPA+ meets all electrical and mechanical specifications required for direct substitution. Differences in product status and compliance certifications do not affect functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

The MAX907CPA+ is a direct functional equivalent to the MAX907CPA. Both devices share identical electrical specifications and physical packaging, ensuring pin-for-pin compatibility and circuit-level interchangeability.

The primary distinction between these parts is product lifecycle status and regulatory compliance. The MAX907CPA is classified as obsolete, while the MAX907CPA+ maintains active production status. The MAX907CPA+ achieves ROHS3 compliance, whereas the original MAX907CPA is RoHS non-compliant. For new designs or systems requiring regulatory compliance with modern environmental standards, the MAX907CPA+ is the appropriate selection. For legacy system maintenance where existing stock of MAX907CPA is available, either part may be used interchangeably based on inventory and compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can MAX907CPA+ be used as a direct replacement for MAX907CPA in existing circuits?

A: Yes. The MAX907CPA+ is electrically and mechanically identical to the MAX907CPA. Both devices feature the same dual TTL comparator configuration, supply voltage range (4.5V ~ 11V), input offset voltage (2mV @ 5V), propagation delay (50ns), and 8-DIP through-hole package. No circuit modifications are required.

Q: What is the difference between MAX907CPA and MAX907CPA+?

A: The devices are functionally equivalent. The MAX907CPA+ differs in product status (active vs. obsolete) and regulatory compliance (ROHS3 compliant vs. RoHS non-compliant). The MAX907CPA+ is supplied in tube packaging, while the MAX907CPA is supplied in bulk packaging.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts maintain identical electrical specifications across all measured parameters, including supply voltage range, input offset voltage, input bias current, quiescent current, CMRR, PSRR, and propagation delay.

Q: Which part should be selected for new designs?

A: The MAX907CPA+ is recommended for new designs due to its active production status and ROHS3 compliance, ensuring long-term availability and alignment with modern environmental regulations.

Q: Is the 8-DIP package compatible with both through-hole and surface-mount PCB layouts?

A: The 8-DIP package is designed for through-hole mounting only. Both MAX907CPA and MAX907CPA+ require through-hole PCB footprints with 0.300" (7.62mm) lead spacing.
