MAX9109ESA-T Equivalent & Substitute Parts

Part Overview

The MAX9109ESA-T is a single-channel comparator with integrated latch functionality, packaged in 8-SOIC surface mount configuration. This device operates from a 4.5V to 5.5V single supply and delivers TTL-compatible output logic levels. The part is classified as obsolete, making identification of active equivalent alternatives essential for ongoing production and design continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX9109ESA-T is determined by strict equivalence across the following critical parameters:

• Single-channel comparator architecture with integrated latch function
• TTL output logic compatibility
• Supply voltage range: 4.5V to 5.5V
• Input offset voltage: 1.6mV maximum at 5V
• Input bias current: 0.125µA maximum at 5V
• Quiescent current: 700µA maximum
• Common-mode rejection ratio and power supply rejection ratio: 86.02dB typical
• Propagation delay: 25ns maximum
• Hysteresis: 2mV
• Operating temperature range: -40°C to 85°C
• Package form factor: 8-SOIC surface mount
• RoHS3 compliance and MSL Level 1 rating

The MAX9109ESA+T meets all these criteria and represents the direct parametric equivalent, differentiated only by packaging format (Tape & Reel versus individual tube packaging) and active product status.

Parameter Comparison

Engineering Selection Recommendations

The MAX9109ESA+T is the direct substitute for the obsolete MAX9109ESA-T. Both parts share identical electrical specifications and mechanical form factors. The primary distinction is product status: the MAX9109ESA+T maintains active manufacturing status, ensuring continued availability and supply chain reliability.

The MAX9109ESA+T is supplied in Tape & Reel packaging format, which is standard for high-volume production environments. Both parts maintain ROHS3 compliance and MSL Level 1 rating, confirming compatibility with modern manufacturing processes and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can the MAX9109ESA+T directly replace the MAX9109ESA-T in existing designs?

A: Yes. The MAX9109ESA+T is electrically and mechanically identical to the MAX9109ESA-T. All electrical parameters, operating ranges, and package dimensions are equivalent. The only difference is packaging format and product status.

Q: What is the difference between the "-T" and "+T" suffix designations?

A: The "-T" suffix indicates tube packaging, while the "+T" suffix indicates Tape & Reel packaging. Both refer to the same die and electrical performance. Tape & Reel format is standard for automated assembly lines.

Q: Is the MAX9109ESA+T suitable for new designs?

A: Yes. The MAX9109ESA+T carries active product status and is recommended for new designs requiring a single-channel TTL comparator with integrated latch in 8-SOIC packaging.

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

A: No. Both parts maintain identical RoHS3 compliance and MSL Level 1 ratings. No additional testing or qualification is required when transitioning from the obsolete to the active part number.

Q: What inventory considerations apply to this substitution?

A: The MAX9109ESA-T is obsolete with limited remaining stock. The MAX9109ESA+T is actively manufactured with higher inventory availability, making it the preferred choice for production continuity.
