ADM6326-24ARTZ-R7 Equivalent & Substitute Parts

Part Overview

The ADM6326-24ARTZ-R7 is a single-channel supervisor IC manufactured by Analog Devices Inc., designed for power management applications requiring reset signal generation. This device operates as a push-pull, totem pole output supervisor with a 2.4V threshold voltage and active-low reset output. The part is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ADM6326-24ARTZ-R7 is determined by strict alignment of the following critical parameters:

• Voltage Threshold: 2.4V (single-channel monitoring requirement)
• Output Type: Push-Pull, Totem Pole configuration
• Reset Logic: Active Low output
• Package: SOT-23-3 form factor (surface mount, three-pin)
• Operating Temperature: -40°C ~ 85°C compatibility
• Functional Type: Simple Reset/Power-On Reset supervisor

The RT9819A-24GVL from Richtek USA Inc. meets all core substitution criteria. Both devices share identical voltage threshold, output configuration, reset logic, package form factor, and operating temperature range. The primary distinction lies in reset timeout specification and product status classification.

Parameter Comparison

Engineering Selection Recommendations

The RT9819A-24GVL qualifies as a direct functional substitute for the ADM6326-24ARTZ-R7 based on matching electrical specifications and package compatibility. The substitute part offers the advantage of active product status, ensuring continued availability and manufacturing support. The RT9819A-24GVL carries ROHS3 compliance certification, meeting modern environmental and regulatory requirements.

The reset timeout differential (100ms minimum for ADM6326 versus 0ms typical for RT9819A) reflects design variations between manufacturers but does not preclude substitution in applications where the original 100ms specification was not a critical design constraint. Applications requiring the specific 100ms reset timeout must evaluate the RT9819A-24GVL's typical 0ms characteristic against system requirements.

The moisture sensitivity level increase from MSL 1 to MSL 3 requires consideration of storage and handling protocols, particularly for extended inventory periods or high-humidity environments.

Frequently Asked Questions (FAQ)

Q: Can the RT9819A-24GVL directly replace the ADM6326-24ARTZ-R7 in existing designs?

A: Yes, the RT9819A-24GVL is electrically and mechanically compatible. Both devices feature identical 2.4V threshold voltage, push-pull totem pole output, active-low reset logic, and SOT-23-3 packaging. Pin-to-pin compatibility is maintained.

Q: What is the significance of the reset timeout difference?

A: The ADM6326-24ARTZ-R7 specifies a 100ms minimum reset timeout, while the RT9819A-24GVL specifies 0ms typical. This difference indicates the time delay before the reset output responds to a threshold violation. Applications designed around the original 100ms specification should evaluate whether the RT9819A-24GVL's timing meets system requirements.

Q: Does the MSL 3 rating of the RT9819A-24GVL affect usability?

A: MSL 3 requires moisture-controlled storage for up to 168 hours before soldering. This is standard for many modern components but requires adherence to proper handling and storage protocols. MSL 1 components like the original ADM6326 have unlimited shelf life without moisture control.

Q: Are there compliance differences between these parts?

A: The RT9819A-24GVL carries ROHS3 compliance certification. Both parts share the same ECCN (EAR99) and HTSUS (8542.39.0001) classifications. The RT9819A-24GVL also carries REACH Unaffected status.

Q: What is the inventory status of these parts?

A: The ADM6326-24ARTZ-R7 is classified as obsolete with 1552 pieces available. The RT9819A-24GVL is active with 667 pieces in stock, ensuring continued availability for future orders.
