ADM1813-5ARTZ-RL Equivalent & Substitute Parts

Part Overview

The ADM1813-5ARTZ-RL is a single-channel supervisor IC in SOT-23-3 surface mount packaging, designed for power supply monitoring and reset circuit applications. This part monitors a 4.62V threshold voltage and provides active-low reset output via open drain or open collector configuration with a 100ms minimum reset timeout. The ADM1813-5ARTZ-RL is classified as obsolete, making equivalent and substitute parts necessary for ongoing production and maintenance applications.

Substitute Part Grouping Explanation

Substitution for the ADM1813-5ARTZ-RL is determined by strict equivalence across the following critical parameters:

Voltage threshold: 4.62V
Number of monitored channels: 1
Output type: Open Drain or Open Collector
Reset polarity: Active Low
Reset timeout: 100ms Minimum
Operating temperature range: -40°C ~ 105°C
Package: SOT-23-3 (TO-236-3, SC-59)
Mounting type: Surface Mount

Substitute parts are grouped into two categories: direct manufacturer equivalents from Analog Devices Inc. with packaging variations, and parametric equivalents from alternative manufacturers (Maxim Integrated, STMicroelectronics) that meet all electrical and mechanical specifications.

Engineering Selection Recommendations

For applications currently using the obsolete ADM1813-5ARTZ-RL, the following selection criteria apply:

Analog Devices Inc. Direct Equivalents: ADM1813-5ARTZ-RL7 and ADM1811-5ARTZ-RL7 are active-status alternatives from the original manufacturer. ADM1813-5ARTZ-RL7 maintains the exact part number lineage with tape & reel packaging. ADM1811-5ARTZ-RL7 offers the same electrical specifications with cut tape and Digi-Reel® packaging options. ADM1811-5ARTZ-REEL provides the highest current inventory (4041 units) in tape & reel format.

Cross-Manufacturer Alternatives: MXD1811UR46+T (Maxim Integrated) and STM1811LWX7F (STMicroelectronics) meet all electrical and mechanical requirements. STM1813LWX7F offers bidirectional open drain output with the highest inventory availability (16969 units).

All substitute parts carry ROHS3 compliance and REACH unaffected status where applicable, supporting regulatory requirements for new production.

Frequently Asked Questions (FAQ)

Q: Can ADM1813-5ARTZ-RL7 be used as a direct replacement for ADM1813-5ARTZ-RL?

A: Yes. Both parts share identical electrical specifications: 4.62V threshold, single-channel monitoring, active-low reset, 100ms minimum timeout, and SOT-23-3 packaging. The primary difference is packaging format (tape & reel versus bulk) and active product status.

Q: What is the difference between ADM1813 and ADM1811 variants?

A: Both ADM1813 and ADM1811 series meet the specified electrical parameters for this application. The ADM1813-5ARTZ-RL7 maintains the original part number designation, while ADM1811 variants offer equivalent functionality with different packaging options and higher inventory availability.

Q: Are STMicroelectronics parts fully compatible?

A: STM1813LWX7F and STM1811LWX7F meet all critical electrical specifications: 4.62V threshold, single-channel monitoring, active-low reset, 100ms timeout, and SOT-23-3 packaging. STM1813LWX7F features bidirectional open drain output. Both are active products with ROHS3 compliance.

Q: What packaging formats are available?

A: Substitute parts are available in three packaging formats: Tape & Reel (TR), Cut Tape (CT) & Digi-Reel®, and bulk. Selection depends on production volume and assembly line requirements. All formats use identical SOT-23-3 component packages.

Q: Are all substitutes RoHS and REACH compliant?

A: All active substitute parts listed carry ROHS3 compliance and REACH unaffected status, supporting regulatory requirements for new production and procurement.
