MAX932EPA+ Equivalent & Substitute Parts

Part Overview

The MAX932EPA+ is a dual comparator with integrated voltage reference, manufactured by Analog Devices Inc./Maxim Integrated. This CMOS/TTL output device operates across single supply (2.5V to 11V) or dual supply (±1.25V to ±5.5V) configurations. The part is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The MAX932EPA+ provides 50mV hysteresis and 12µs maximum propagation delay in an 8-DIP through-hole package.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the MAX932EPA+ is based on the following critical parameters that must remain compatible:

• Package Type: 8-DIP through-hole form factor (0.300", 7.62mm)
• Functional Elements: Dual comparator with integrated voltage reference
• Output Configuration: CMOS/TTL output capability
• Supply Voltage Range: Minimum coverage of 2.5V to 11V single supply or equivalent dual supply
• Input Offset Voltage: Maximum 10mV @ 5V
• Hysteresis: 50mV
• CMRR/PSRR: 80dB minimum for both parameters
• Compliance: ROHS3 compliant, REACH unaffected

The LTC1442CN8#PBF and LTC1442IN8#PBF meet these substitution criteria. Both are manufactured by Analog Devices Inc. and provide identical functional performance with active product status, ensuring long-term availability and support.

Parameter Comparison

Engineering Selection Recommendations

Both LTC1442 variants are active products from Analog Devices Inc., providing superior long-term availability compared to the obsolete MAX932EPA+. Selection between the two LTC1442 options depends on operating temperature requirements:

LTC1442IN8#PBF is the preferred substitute for applications requiring the full -40°C to 85°C operating temperature range, matching the MAX932EPA+ specification exactly.

LTC1442CN8#PBF is suitable for applications operating within the 0°C to 70°C range, offering equivalent electrical performance with reduced temperature coverage.

Both substitutes maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with the original part. The LTC1442 series exhibits slightly higher propagation delay (15µs versus 12µs) and marginally lower quiescent current (5.7µA versus 6µA), both within acceptable engineering tolerances for dual comparator applications.

Frequently Asked Questions (FAQ)

Q: Can LTC1442CN8#PBF and LTC1442IN8#PBF be used interchangeably with MAX932EPA+?

A: Both LTC1442 variants are pin-compatible and functionally equivalent substitutes. The primary difference is operating temperature range. LTC1442IN8#PBF covers -40°C to 85°C (matching MAX932EPA+), while LTC1442CN8#PBF operates 0°C to 70°C. Select based on your application's temperature requirements.

Q: What are the key electrical differences between MAX932EPA+ and LTC1442 substitutes?

A: Input offset voltage, hysteresis, CMRR, and PSRR specifications are identical. LTC1442 exhibits 3µs longer propagation delay (15µs vs. 12µs) and 0.3µA lower quiescent current. Supply voltage ranges are nearly identical, with LTC1442 supporting 2V minimum versus 2.5V for MAX932EPA+.

Q: Are the packages identical?

A: Yes. Both MAX932EPA+ and LTC1442CN8#PBF/LTC1442IN8#PBF use 8-DIP through-hole packages (0.300", 7.62mm). No PCB layout modifications are required for substitution.

Q: Do the substitute parts meet the same compliance standards?

A: Yes. Both LTC1442 variants are ROHS3 compliant and REACH unaffected, matching the MAX932EPA+ compliance profile.

Q: Why is MAX932EPA+ obsolete?

A: The MAX932EPA+ has been discontinued by the manufacturer. The LTC1442 series represents the active replacement offering equivalent functionality with improved product lifecycle support.
