DS1813R-5/T&R Equivalent & Substitute Parts

Part Overview

The DS1813R-5/T&R is a single-channel power management supervisor IC from Analog Devices Inc./Maxim Integrated, designed for reset and power-on reset applications. This component operates as an open drain or open collector supervisor with a 4.62V threshold voltage and 100ms minimum reset timeout. The part is currently listed as obsolete, making equivalent and substitute parts necessary for ongoing system support and new design implementations. Substitute parts maintain identical electrical and mechanical specifications while offering improved product status and compliance certifications.

Substitute Part Grouping Explanation

Substitution for the DS1813R-5/T&R is determined by strict equivalence across the following critical parameters:

Electrical Specifications:

• Voltage threshold: 4.62V
• Output type: Open Drain or Open Collector
• Reset polarity: Active Low
• Reset timeout: 100ms Minimum
• Operating temperature range: -40°C ~ 85°C (TA)
• Number of monitored voltages: 1 channel

Mechanical & Package Specifications:

• Mounting type: Surface Mount
• Package: SOT-23-3 (TO-236-3, SC-59)
• Moisture sensitivity level: 1 (Unlimited)

Regulatory & Compliance:

• REACH Status: REACH Unaffected
• ECCN: EAR99
• HTSUS: 8542.39.0001

The substitute parts DS1813R-5+T&R and DS1811R-5+T&R meet all electrical and mechanical requirements for direct substitution. Both are available in active product status with improved RoHS3 compliance compared to the obsolete main part.

Parameter Comparison

Engineering Selection Recommendations

DS1813R-5+T&R (Direct Substitute): This part is the primary substitute for the obsolete DS1813R-5/T&R. It maintains identical electrical and mechanical specifications while offering active product status and ROHS3 compliance. The packaging format differs (Cut Tape & Digi-Reel® versus Tape & Reel), which may affect procurement workflows but does not impact electrical performance or PCB assembly compatibility.

DS1811R-5+T&R (Parametric Equivalent): This part provides an alternative from the same EconoReset series with identical electrical performance and package specifications. It is also in active product status with ROHS3 compliance. The base product number differs (DS1811 versus DS1813), but all monitored parameters remain equivalent for reset and power-on reset applications.

Both substitute parts address the obsolescence of the main part while providing improved regulatory compliance and active manufacturer support.

Frequently Asked Questions (FAQ)

Q: Can DS1813R-5+T&R be used as a direct replacement for DS1813R-5/T&R? A: Yes. Both parts share identical electrical specifications (4.62V threshold, 100ms reset timeout, active low reset, open drain/collector output) and mechanical packaging (SOT-23-3). The only difference is product status (active versus obsolete) and RoHS compliance (ROHS3 versus non-compliant). Packaging format differs (Cut Tape & Digi-Reel® versus Tape & Reel), but this does not affect circuit functionality or PCB assembly.

Q: What is the difference between DS1813R-5+T&R and DS1811R-5+T&R? A: Both parts are parametrically equivalent with identical electrical performance and package specifications. The base product number differs (DS1813 versus DS1811), but all critical parameters—voltage threshold, reset timeout, output type, operating temperature, and package—are identical. Selection between these parts depends on inventory availability and procurement preferences.

Q: Are the substitute parts compatible with existing PCB designs for DS1813R-5/T&R? A: Yes. Both substitute parts use the SOT-23-3 package with identical pin configuration and electrical characteristics. No PCB layout modifications are required for substitution.

Q: What is the significance of the packaging format difference (T&R versus CT & Digi-Reel®)? A: Tape & Reel (T&R) and Cut Tape (CT) & Digi-Reel® are different supply formats for surface mount components. T&R is continuous reel packaging, while CT & Digi-Reel® offers cut tape with optional reel options. Both formats are compatible with standard pick-and-place assembly equipment. The choice depends on production volume and procurement requirements.

Q: Why is the main part DS1813R-5/T&R listed as obsolete? A: Obsolescence indicates the manufacturer has discontinued active production and support. Substitute parts in active status ensure continued availability, manufacturer technical support, and compliance with current regulatory standards.

Q: Are there any compliance differences between the main part and substitutes? A: Yes. The main part is RoHS non-compliant, while both substitute parts are ROHS3 compliant. All parts maintain REACH Unaffected status and identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications.
