Substitute Part Grouping Explanation

Substitution of the ADM1816-R22ARTZ-RL is determined by strict equivalence across the following critical parameters:

• Manufacturer and Base Product Series: Both parts must be from Analog Devices Inc. ADM1816 series to ensure functional and electrical compatibility
• Voltage Threshold: 2.18V threshold must be maintained for proper power supply monitoring
• Output Configuration: Open drain or open collector output is required for reset signal generation
• Reset Logic and Timeout: Active low reset with 100ms minimum timeout ensures compatible system behavior
• Operating Temperature Range: -40°C ~ 105°C maintains thermal compatibility with target applications
• Package Type: SOT-23-3 surface mount package ensures mechanical and thermal compatibility
• Moisture Sensitivity Level: MSL 1 (Unlimited) classification must be preserved

The ADM1816-R22ARTZ-R7 qualifies as a direct substitute based on identical electrical specifications and package configuration.

Parameter Comparison

Engineering Selection Recommendations

The ADM1816-R22ARTZ-R7 is the qualified substitute for the obsolete ADM1816-R22ARTZ-RL. Both parts share identical electrical and mechanical specifications, ensuring direct functional compatibility in existing circuit designs.

The substitute part maintains ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component manufacturing and distribution.

Selection of the ADM1816-R22ARTZ-R7 eliminates obsolescence risk while preserving all electrical performance characteristics required for power supply supervision applications.

Frequently Asked Questions (FAQ)

Q: Can the ADM1816-R22ARTZ-R7 be used as a direct replacement for the ADM1816-R22ARTZ-RL?

A: Yes. Both parts are electrically and mechanically identical. The ADM1816-R22ARTZ-R7 provides the same voltage threshold (2.18V), output configuration (open drain or open collector), reset logic (active low), and operating temperature range (-40°C ~ 105°C). No circuit modifications are required.

Q: What is the primary difference between these two part numbers?

A: The ADM1816-R22ARTZ-RL is obsolete, while the ADM1816-R22ARTZ-R7 is active. The suffix difference (-RL versus -R7) indicates different manufacturing date codes and tape/reel packaging configurations. Electrical performance is identical.

Q: Are there any compliance or certification differences?

A: The ADM1816-R22ARTZ-R7 includes documented ROHS3 compliance and REACH unaffected status. Both parts maintain MSL 1 (Unlimited) moisture sensitivity classification and EAR99 export control designation.

Q: Is the SOT-23-3 package identical for both parts?

A: Yes. Both parts use the same SOT-23-3 surface mount package (also designated TO-236-3 or SC-59). PCB footprints and thermal characteristics are identical.

Q: What inventory considerations apply to these parts?

A: The ADM1816-R22ARTZ-RL has 664 pieces in stock as new original inventory. The ADM1816-R22ARTZ-R7 has 2180 pieces in stock as new original inventory, providing greater availability for new production orders and design implementations.
