Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX6324FUT26-T is determined by strict equivalence across the following critical parameters:

• Voltage threshold specification (2.63V)
• Single-channel voltage monitoring capability
• Open drain or open collector output configuration
• Active low reset logic
• Minimum 100ms reset timeout
• SOT-23-6 package compatibility
• Surface mount mounting type
• Operating temperature range (-40°C ~ 125°C)

The MAX6324FUT26+T meets all these criteria and is therefore a direct functional equivalent. The primary distinction between these parts is product status and compliance certification, not electrical or mechanical characteristics.

Parameter Comparison

Engineering Selection Recommendations

The MAX6324FUT26+T is the direct substitute for the MAX6324FUT26-T. Both parts share identical electrical and mechanical specifications, including voltage threshold, output configuration, reset characteristics, and package format.

The MAX6324FUT26+T is preferred for new designs and production applications due to its active product status and ROHS3 compliance certification. The original MAX6324FUT26-T, classified as obsolete, should be replaced in active production schedules.

Both parts maintain REACH unaffected status and EAR99 export classification. The MSL rating of 1 (Unlimited) applies to both variants, indicating no moisture sensitivity constraints during storage or handling.

Frequently Asked Questions (FAQ)

Q: Can MAX6324FUT26+T directly replace MAX6324FUT26-T in existing designs?

A: Yes. Both parts are electrically and mechanically identical. The substitution requires no circuit modifications or PCB layout changes. Pin configuration, voltage threshold, output behavior, and operating temperature range are equivalent.

Q: What is the difference between MAX6324FUT26-T and MAX6324FUT26+T?

A: The parts differ in product status and compliance certification. MAX6324FUT26-T is obsolete and RoHS non-compliant. MAX6324FUT26+T is active and ROHS3 compliant. All functional parameters are identical.

Q: Are there packaging differences between these parts?

A: No. Both parts use SOT-23-6 surface mount packaging. The supplier device package designation is SOT-6 for both variants. PCB footprints are identical.

Q: What does the voltage threshold of 2.63V mean for substitution?

A: The 2.63V threshold is the voltage level at which the supervisor circuit triggers its reset output. Any substitute must maintain this exact threshold specification to ensure proper system operation. Both listed parts meet this requirement.

Q: Is the active low reset logic critical for substitution?

A: Yes. The reset output is active low, meaning the output is pulled low when a reset condition is triggered. Any substitute must maintain this logic polarity. The MAX6324FUT26+T preserves this characteristic.

Q: What does open drain or open collector output mean?

A: This output configuration allows the device to pull the output line low but does not actively drive it high. An external pull-up resistor is required. Both parts use this configuration identically.
