MAX9117EXK-T Equivalent & Substitute Parts

Part Overview

The MAX9117EXK-T is a single-channel comparator with integrated voltage reference manufactured by Analog Devices Inc./Maxim Integrated. This device features CMOS push-pull, rail-to-rail output architecture in a 5-pin SC-70 surface mount package. The part is currently listed as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. The MAX9117EXK-T operates across a 1.6V to 5.5V supply range with low input offset voltage and minimal quiescent current consumption, suitable for battery-powered and low-power analog signal conditioning circuits.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX9117EXK-T is determined by the following critical parameters:

Electrical Compatibility Criteria:

• Supply voltage range must encompass or match the 1.6V ~ 5.5V specification
• Output type must be push-pull, rail-to-rail configuration
• Package must be 5-TSSOP (SC-70-5, SOT-353) for mechanical and thermal compatibility
• Operating temperature range must cover -40°C ~ 85°C
• Input offset voltage, propagation delay, and hysteresis must be within acceptable application tolerances

Compliance Requirements:

• RoHS3 compliance status
• MSL rating of 1 or equivalent
• ECCN and HTSUS classifications for regulatory alignment

The substitute parts identified are grouped into two categories: direct packaging equivalents and functionally compatible alternatives with minor parameter variations.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: MAX9117EXK+T

The MAX9117EXK+T is the direct functional equivalent of the MAX9117EXK-T, manufactured by the same supplier (Analog Devices Inc./Maxim Integrated). This part maintains identical electrical specifications, package configuration, and compliance certifications. The primary distinction is product status: MAX9117EXK+T is active with 17,200 units in stock, whereas the original MAX9117EXK-T is obsolete. This substitute provides seamless drop-in replacement capability with no circuit redesign required.

Secondary Substitutes: LMV7219M7/NOPB and LMV7219M7X/NOPB

The Texas Instruments LMV7219 series comparators are functionally compatible alternatives for applications where the reduced supply voltage floor of 2.7V (versus 1.6V) is acceptable. Both variants are active products with substantial inventory availability (25,200 and 17,100 units respectively). Key parameter differences include:

• Reduced minimum supply voltage (2.7V vs. 1.6V) eliminates ultra-low voltage operation capability
• Slightly higher input offset voltage (6mV vs. 5mV) and hysteresis (7.5mV vs. 4mV)
• Significantly faster propagation delay (20ns vs. 40µs) provides improved response time
• Higher quiescent current (1.8mA vs. 1.6µA) increases power consumption
• Enhanced CMRR specification (85dB vs. not specified) improves supply noise rejection

These substitutes are suitable for applications operating at 2.7V or higher where the faster response time and improved noise rejection justify the increased power consumption and relaxed hysteresis specification.

Frequently Asked Questions (FAQ)

Q: Can MAX9117EXK+T replace MAX9117EXK-T without circuit modification?

A: Yes. The MAX9117EXK+T is electrically and mechanically identical to the MAX9117EXK-T. Both parts share the same supply voltage range (1.6V ~ 5.5V), output specifications, and 5-TSSOP package. No circuit redesign is required.

Q: What are the key differences between MAX9117EXK-T and LMV7219M7/NOPB?

A: The primary differences are supply voltage range and propagation delay. The MAX9117 operates from 1.6V, while the LMV7219 requires minimum 2.7V. The LMV7219 offers significantly faster propagation delay (20ns vs. 40µs). Applications requiring ultra-low voltage operation must use the MAX9117 series. Applications prioritizing response speed may benefit from the LMV7219.

Q: Are LMV7219M7/NOPB and LMV7219M7X/NOPB interchangeable?

A: Yes. Both variants are electrically identical Texas Instruments LMV7219 comparators in 5-TSSOP packaging. The designation difference reflects packaging format (Cut Tape vs. Digi-Reel). Electrical performance and pin configuration are identical.

Q: What is the impact of higher hysteresis in LMV7219 substitutes?

A: The LMV7219 series specifies 7.5mV hysteresis compared to 4mV in the MAX9117. Hysteresis prevents oscillation near the threshold voltage. Higher hysteresis requires larger input signal changes to trigger output transitions. Applications with slow-moving input signals or noise-sensitive thresholds may require circuit adjustment or remain with the MAX9117 series.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. MAX9117EXK+T, LMV7219M7/NOPB, and LMV7219M7X/NOPB are all ROHS3 compliant with MSL rating 1 (unlimited moisture sensitivity level), matching the original MAX9117EXK-T compliance profile.

Q: Which substitute is recommended for new designs?

A: For new designs requiring 1.6V minimum supply voltage, use MAX9117EXK+T (active product status, identical specifications). For designs operating at 2.7V or higher where faster response time is beneficial, either LMV7219M7/NOPB or LMV7219M7X/NOPB provides enhanced performance with active product support from Texas Instruments.
