MAX982ESA-T Equivalent & Substitute Parts

Part Overview

The MAX982ESA-T is a dual comparator with integrated voltage reference in 8-SOIC surface mount packaging, manufactured by Analog Devices Inc./Maxim Integrated. This device is classified as obsolete, making equivalent and substitute parts necessary for ongoing production and maintenance applications. The part operates across a wide supply voltage range (2.5V to 11V single supply, ±1.25V to ±5.5V dual supply) and includes integrated hysteresis of 50mV for stable threshold detection.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the MAX982ESA-T is determined by the following critical parameters:

• Functional equivalence: Dual comparator with integrated voltage reference
• Electrical specifications: Supply voltage range (2.5V ~ 11V single, ±1.25V ~ 5.5V dual), input offset voltage (10mV @ 5V maximum), hysteresis (50mV), CMRR/PSRR (80dB typical)
• Package compatibility: 8-SOIC surface mount form factor
• Operating temperature: -40°C ~ 85°C
• Compliance: ROHS3 compliant, MSL 1 rating

The identified substitutes maintain these core parameters while differing in packaging format (tape & reel vs. tube) and product status (active vs. obsolete). Output type variations (standard vs. open-drain) are noted where applicable.

Parameter Comparison

Engineering Selection Recommendations

MAX982ESA+T is the direct equivalent substitute. It maintains identical electrical specifications and package form factor as the MAX982ESA-T while offering active product status and higher inventory availability (3600 pcs vs. 636 pcs). The primary difference is packaging format (tape & reel vs. tube), which affects procurement and handling but not electrical performance or board-level compatibility.

LTC1842IS8#PBF is the manufacturer-recommended alternative from Analog Devices Inc. This part meets all core electrical requirements and maintains the same 8-SOIC package footprint. The LTC1842IS8#PBF features open-drain output architecture and a specified propagation delay of 12µs, compared to unspecified propagation delay in the MAX982ESA-T. The open-drain output requires external pull-up resistors and may necessitate circuit topology adjustments. This part is active and ROHS3 compliant with MSL 1 rating.

Both substitutes are ROHS3 compliant and carry MSL 1 (unlimited moisture sensitivity) ratings, matching the compliance profile of the original part.

Frequently Asked Questions (FAQ)

Q: Can MAX982ESA+T be used as a direct replacement for MAX982ESA-T?

A: Yes. The MAX982ESA+T is electrically and mechanically identical to the MAX982ESA-T. The only difference is packaging format (tape & reel vs. tube). Both parts are 8-SOIC surface mount devices with identical electrical specifications, operating temperature range, and compliance certifications.

Q: What is the key difference between MAX982ESA+T and LTC1842IS8#PBF?

A: The primary difference is output type. The MAX982ESA+T has standard comparator outputs, while the LTC1842IS8#PBF features open-drain outputs. Open-drain outputs require external pull-up resistors to establish logic levels. Both parts share identical supply voltage ranges, input offset voltage, hysteresis, and CMRR/PSRR specifications. The LTC1842IS8#PBF specifies a 12µs propagation delay.

Q: Are all three parts pin-compatible?

A: All three parts use the 8-SOIC package with identical pinout and footprint. However, the LTC1842IS8#PBF open-drain output architecture may require circuit modifications if the original design assumes standard comparator outputs with defined high-level output voltage.

Q: Do packaging format differences affect electrical performance?

A: No. Tape & reel (TR) and tube packaging formats are logistics and handling variations only. They do not affect electrical specifications, performance, or reliability of the component.

Q: Are all substitutes RoHS compliant?

A: Yes. All three parts—MAX982ESA-T, MAX982ESA+T, and LTC1842IS8#PBF—are ROHS3 compliant with MSL 1 (unlimited) moisture sensitivity ratings.
