MAX932CSA-T Equivalent & Substitute Parts

Part Overview

The MAX932CSA-T is a dual comparator with integrated voltage reference, manufactured by Analog Devices Inc./Maxim Integrated. This 8-SOIC surface-mount linear IC combines CMOS and TTL output stages with a built-in voltage reference, designed for precision analog signal comparison applications. The part is currently obsolete, making equivalent and substitute parts necessary for ongoing production and maintenance applications. Active alternatives with identical or enhanced electrical characteristics are available from the same manufacturer family.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the MAX932CSA-T is determined by the following critical parameters:

• Package compatibility: 8-SOIC form factor with 0.154" width (3.90mm)
• Electrical specifications: Supply voltage range (2.5V ~ 11V single, ±1.25V ~ 5.5V dual), input offset voltage (10mV @ 5V), quiescent current (≤6µA), CMRR/PSRR (80dB), propagation delay (12µs), hysteresis (50mV)
• Functional equivalence: Dual comparator with integrated voltage reference
• Output stage compatibility: CMOS/TTL or Open-Drain output types
• Operating temperature range: Minimum 0°C ~ 70°C

Substitute parts are grouped into two categories:

Direct Substitutes (Pin-Compatible, Same Output Stage):

• MAX932CSA+T: Active product status, identical electrical specifications, ROHS3 compliant

Functional Equivalents (Pin-Compatible, Different Output Stage):

• LTC1842CS8#PBF, LTC1842CS8#TRPBF: Open-Drain output, identical electrical specifications, ROHS3 compliant, commercial temperature range
• LTC1842IS8#PBF, LTC1842IS8#TRPBF: Open-Drain output, identical electrical specifications, ROHS3 compliant, industrial temperature range (-40°C ~ 85°C)

All substitute parts maintain the same package footprint, pin count, and core electrical performance parameters required for direct circuit board replacement.

Parameter Comparison

Engineering Selection Recommendations

For direct replacement with identical output stage characteristics: Select MAX932CSA+T. This part maintains CMOS/TTL output compatibility with the original MAX932CSA-T while offering active product status and ROHS3 compliance. Electrical specifications are identical across all critical parameters.

For applications requiring extended temperature range: Select LTC1842IS8#PBF or LTC1842IS8#TRPBF. These industrial-grade variants extend the operating temperature range to -40°C ~ 85°C, providing enhanced performance in temperature-sensitive environments. The Open-Drain output stage requires external pull-up resistors but maintains all core electrical specifications.

For commercial temperature applications with Open-Drain output: Select LTC1842CS8#PBF or LTC1842CS8#TRPBF. These parts operate within the 0°C ~ 70°C commercial range and are suitable for standard industrial applications. Choose Tube packaging (LTC1842CS8#PBF) for small quantities or Tape & Reel (LTC1842CS8#TRPBF) for high-volume production.

For RoHS compliance requirements: All substitute parts (MAX932CSA+T and LTC1842 series) are ROHS3 compliant. The original MAX932CSA-T is RoHS non-compliant and should be replaced with any of the listed alternatives for new designs or compliance-driven applications.

Frequently Asked Questions (FAQ)

Q: Can LTC1842 series parts directly replace MAX932CSA-T without circuit modifications?

A: LTC1842 parts are pin-compatible and functionally equivalent but feature Open-Drain output instead of CMOS/TTL output. Circuits designed for CMOS/TTL output require external pull-up resistors when using LTC1842 variants. MAX932CSA+T provides direct replacement without circuit modifications.

Q: What is the difference between Tube and Tape & Reel packaging options?

A: Tube packaging (LTC1842CS8#PBF, LTC1842IS8#PBF) is suitable for small-quantity orders and manual assembly. Tape & Reel packaging (LTC1842CS8#TRPBF, LTC1842IS8#TRPBF) is designed for automated pick-and-place assembly and high-volume production. Electrical specifications are identical between packaging options.

Q: Why should I choose LTC1842IS8 over LTC1842CS8?

A: LTC1842IS8 variants operate across -40°C ~ 85°C (industrial temperature range) compared to LTC1842CS8's 0°C ~ 70°C (commercial range). Select LTC1842IS8 for applications requiring extended temperature performance or operation in harsh environments.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. MAX932CSA+T and all LTC1842 variants are ROHS3 compliant. The original MAX932CSA-T is RoHS non-compliant. For new designs or applications with RoHS compliance requirements, use any of the listed substitute parts.

Q: What is the impact of Open-Drain output on circuit design?

A: Open-Drain output requires an external pull-up resistor to a supply voltage. This configuration provides greater flexibility for interfacing with different logic levels but requires additional component placement compared to CMOS/TTL output stages. Ensure pull-up resistor values are selected based on load requirements and switching speed specifications.

Q: Can I use LTC1842 parts in existing MAX932CSA-T designs without PCB modifications?

A: LTC1842 parts are pin-compatible and fit the same 8-SOIC footprint. However, the Open-Drain output stage requires external pull-up resistors if the original design relied on CMOS/TTL output characteristics. Verify output stage compatibility with your circuit topology before substitution.

Q: Which substitute part offers the highest inventory availability?

A: LTC1842IS8#TRPBF offers the highest inventory with 8502 pieces in stock, followed by LTC1842IS8#PBF with 2994 pieces. Both are industrial-grade variants with extended temperature range and active product status.
