Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX901ACSE-T is determined by strict equivalence across the following critical parameters:

• Functional equivalence: Four independent general-purpose comparator elements with TTL output
• Electrical compatibility: Identical supply voltage range (5V ~ 10V single, ±2.5V ~ 5V dual), input offset voltage (2mV @ ±5V), input bias current (6µA @ ±5V), and CMRR/PSRR specifications (86.02dB)
• Package compatibility: 16-SOIC surface-mount package with identical physical dimensions (0.154", 3.90mm width)
• Operating temperature range: 0°C ~ 70°C
• Compliance requirements: ROHS3 compliance and MSL 1 rating

The MAX901ACSE+T qualifies as a direct substitute based on identical electrical specifications and package configuration. The primary distinction is packaging format: the substitute is supplied in Tape & Reel (TR) format versus the original tube packaging, and product status is Active rather than Obsolete.

Engineering Selection Recommendations

The MAX901ACSE+T is a direct functional and electrical equivalent to the MAX901ACSE-T. Selection of the substitute is justified by the following factors:

• Product lifecycle: The MAX901ACSE-T is classified as obsolete, while the MAX901ACSE+T maintains active production status, ensuring long-term availability and supply chain reliability.
• Electrical equivalence: All critical electrical parameters are identical, including supply voltage range, input offset voltage, input bias current, and frequency response characteristics (CMRR/PSRR).
• Package compatibility: Both devices use the identical 16-SOIC surface-mount package with matching pinout and physical dimensions, enabling direct PCB-level substitution without layout modifications.
• Compliance alignment: Both parts maintain ROHS3 compliance and MSL 1 rating, meeting current environmental and reliability standards.
• Packaging consideration: The substitute is supplied in Tape & Reel format, which is standard for high-volume production environments and automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the MAX901ACSE+T be used as a direct replacement for the MAX901ACSE-T in existing designs?

A: Yes. The MAX901ACSE+T is electrically and functionally identical to the MAX901ACSE-T across all specified parameters. Both devices feature four TTL-output comparators with identical supply voltage ranges, input offset voltage, input bias current, and CMRR/PSRR specifications. The 16-SOIC package pinout is identical, enabling direct substitution without circuit modifications.

Q: What is the difference between the MAX901ACSE-T and MAX901ACSE+T?

A: The primary differences are product status and packaging format. The MAX901ACSE-T is obsolete and typically supplied in tube packaging, while the MAX901ACSE+T is an active product supplied in Tape & Reel (TR) format. All electrical specifications and package dimensions are identical.

Q: Is the Tape & Reel packaging compatible with automated assembly equipment?

A: Yes. Tape & Reel (TR) packaging is the standard format for automated surface-mount assembly processes. The MAX901ACSE+T in TR format is compatible with standard pick-and-place equipment and reflow soldering processes used in high-volume production.

Q: Are there any compliance or certification differences between these parts?

A: No. Both the MAX901ACSE-T and MAX901ACSE+T maintain identical ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity ratings. Both parts meet current environmental and reliability standards.

Q: What supply voltage configurations does the MAX901ACSE+T support?

A: The MAX901ACSE+T operates with single supply voltage from 5V to 10V or dual supply voltage from ±2.5V to ±5V, providing flexibility for both single-supply and dual-supply circuit designs.

Q: Are the input offset voltage and input bias current specifications identical?

A: Yes. Both devices specify a maximum input offset voltage of 2mV at ±5V and a maximum input bias current of 6mV at ±5V, ensuring equivalent precision and input impedance characteristics.
