Substitute Part Grouping Explanation

Substitution of the MAX966ESA-T is based on strict electrical and mechanical parameter matching within the general-purpose comparator category. The critical parameters determining substitutability are:

  • Dual comparator configuration (2 elements)
  • Open-drain, rail-to-rail output topology
  • 8-SOIC surface-mount package with 0.154" (3.90mm) width
  • Supply voltage range: 1.6V to 5.5V
  • Operating temperature range: -40°C to 85°C
  • RoHS3 compliance and MSL Level 1 rating

The MAX966ESA+T is identified as a direct equivalent based on identical electrical specifications and package configuration. The primary distinction is packaging format: the original part uses tube packaging, while the substitute uses Tape & Reel (TR) format. Both parts share the same base product number (MAX966) and maintain full parameter compatibility.

Engineering Selection Recommendations

The MAX966ESA+T is the direct substitute for the obsolete MAX966ESA-T. Both parts are manufactured by the same supplier and maintain identical electrical and mechanical specifications across all critical parameters. The MAX966ESA+T carries active product status, ensuring ongoing availability and manufacturer support.

Selection of the MAX966ESA+T is appropriate for new designs and production continuity. Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements. The packaging format difference (Tape & Reel versus tube) does not affect functional performance and is determined by procurement and assembly requirements.

Frequently Asked Questions (FAQ)

Q: Can MAX966ESA+T be used as a direct replacement for MAX966ESA-T in existing designs?

A: Yes. Both parts are electrically and mechanically identical. All electrical parameters, including supply voltage range, input offset, propagation delay, and output characteristics, are identical. The 8-SOIC package dimensions and pin configuration are unchanged.

Q: What is the difference between MAX966ESA-T and MAX966ESA+T?

A: The primary difference is packaging format. MAX966ESA-T uses tube packaging, while MAX966ESA+T uses Tape & Reel (TR) format. This distinction affects procurement and assembly processes but does not impact electrical performance or functional compatibility.

Q: Why is the MAX966ESA-T classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production of this specific part number variant. The MAX966ESA+T remains in active production and provides equivalent functionality.

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

A: No. Both parts maintain identical RoHS3 compliance, REACH unaffected status, ECCN classification (EAR99), and HTSUS codes. Moisture sensitivity level (MSL 1) is identical for both.

Q: What are the critical parameters for substitution compatibility?

A: Substitution compatibility is determined by: dual comparator configuration, open-drain rail-to-rail output, 8-SOIC package, 1.6V to 5.5V supply voltage range, -40°C to 85°C operating temperature, and identical electrical specifications including input offset, propagation delay, and hysteresis characteristics.

Q: Can the Tape & Reel packaging of MAX966ESA+T be used in manual assembly processes?

A: Tape & Reel packaging is designed for automated pick-and-place assembly. Manual assembly processes typically require tube or tray packaging. Procurement should confirm packaging format compatibility with assembly capabilities.
