MAX982CSA-T Equivalent & Substitute Parts

Part Overview

The MAX982CSA-T is a dual comparator with integrated voltage reference manufactured by Analog Devices Inc./Maxim Integrated. This 8-SOIC surface mount device operates across a supply voltage range of 2.5V to 11V (single supply) or ±1.25V to 5.5V (dual supply), with a maximum input offset voltage of 10mV at 5V and built-in 50mV hysteresis. The device is classified as obsolete, making identification of active equivalent parts essential for new designs and production continuity.

Substitute Part Grouping Explanation

Substitution of the MAX982CSA-T is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part MAX982CSA+T maintains identical functional specifications including supply voltage range, input offset voltage, quiescent current, CMRR/PSRR performance, hysteresis characteristics, and operating temperature range. Both parts share the same 8-SOIC package footprint and surface mount mounting type, ensuring mechanical compatibility in PCB layouts.

The primary distinction between these parts is packaging format: MAX982CSA-T is supplied in tube packaging, while MAX982CSA+T is supplied in Tape & Reel (TR) format. Additionally, MAX982CSA+T carries an Active product status, whereas MAX982CSA-T is classified as Obsolete. Both parts meet ROHS3 compliance and MSL 1 specifications.

Substitution is valid when all of the following criteria are met:

• Identical supply voltage range (2.5V ~ 11V single, ±1.25V ~ 5.5V dual)
• Matching input offset voltage specification (10mV @ 5V maximum)
• Equivalent quiescent current (6µA maximum)
• Same CMRR and PSRR performance (80dB each)
• Identical hysteresis value (50mV)
• Compatible operating temperature range (0°C ~ 70°C)
• Same package type (8-SOIC)
• Surface mount compatibility

Engineering Selection Recommendations

The MAX982CSA+T is the direct functional equivalent of the MAX982CSA-T. Selection between these parts should be based on the following engineering and supply chain considerations:

For new designs and production environments requiring high-volume component procurement, MAX982CSA+T is the recommended choice. This part carries Active product status from the manufacturer, ensuring long-term availability and continued manufacturing support. The Tape & Reel packaging format is optimized for automated assembly processes, reducing handling costs and improving placement accuracy in surface mount production.

For legacy system maintenance or low-volume applications where existing tube-packaged inventory of MAX982CSA-T remains available, continued use of the obsolete part number is electrically and mechanically valid. However, future procurement should transition to MAX982CSA+T to avoid supply discontinuation risks.

Both parts maintain identical ROHS3 compliance and REACH Unaffected status, satisfying regulatory requirements for commercial and industrial applications. The MSL 1 rating for both parts indicates unlimited shelf life under standard storage conditions, eliminating moisture-related component degradation concerns.

Frequently Asked Questions (FAQ)

Q: Can MAX982CSA+T be used as a direct replacement for MAX982CSA-T in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters. The 8-SOIC footprint, pin configuration, and electrical performance are equivalent. The only differences are product status (Active vs. Obsolete) and packaging format (Tape & Reel vs. Tube).

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

A: Tube packaging is used for manual handling and small-quantity orders, while Tape & Reel (TR) packaging is designed for automated pick-and-place assembly equipment. Both formats contain the same component with identical electrical specifications. Selection depends on manufacturing process requirements and order volume.

Q: Why is MAX982CSA-T marked as Obsolete?

A: Obsolete status indicates the manufacturer has discontinued active production of this specific part number variant. MAX982CSA+T remains in active production as the current equivalent offering. For new designs, MAX982CSA+T should be specified to ensure supply continuity.

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

A: No. Both parts share identical electrical specifications: 2.5V to 11V supply voltage range, 10mV maximum input offset voltage at 5V, 6µA maximum quiescent current, 80dB CMRR and PSRR, and 50mV hysteresis.

Q: Do both parts meet the same compliance standards?

A: Yes. Both MAX982CSA-T and MAX982CSA+T are ROHS3 compliant, REACH Unaffected, and carry MSL 1 moisture sensitivity rating. Regulatory and environmental compliance is identical.

Q: What is the inventory status for these parts?

A: MAX982CSA-T has 755 pieces in stock (new original). MAX982CSA+T has 1031 pieces in stock (new original). Availability may vary by distributor and time of inquiry.
