DS1814AR-10/T&R Equivalent & Substitute Parts

Part Overview

The DS1814AR-10/T&R is a single-channel power supply supervisor IC manufactured by Analog Devices Inc./Maxim Integrated, designed for power-on reset and simple reset applications. This component monitors a single voltage rail and provides push-pull output control with active-low reset functionality. The part is classified as obsolete, which necessitates identification of functionally equivalent alternatives for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DS1814AR-10/T&R is determined by strict equivalence across the following critical parameters:

• Single voltage monitoring channel with fixed 4.375V threshold
• Push-pull, totem-pole output configuration for active-low reset control
• 140ms minimum reset timeout specification
• SOT-23-5 package (SC-74A, SOT-753) for surface-mount PCB compatibility
• Operating temperature range of -40°C to 85°C
• Active-low reset logic for system initialization control

The identified substitute maintains identical electrical specifications and mechanical compatibility, differing only in packaging format and product status classification.

Parameter Comparison

Engineering Selection Recommendations

The DS1814AR-10+T&R serves as the direct functional equivalent to the obsolete DS1814AR-10/T&R. Both parts are manufactured by Analog Devices Inc./Maxim Integrated and maintain identical electrical and mechanical specifications across all critical parameters. The substitute part carries Active product status, ensuring continued availability and manufacturing support.

Selection of the DS1814AR-10+T&R is appropriate for new designs and replacement procurement. The primary distinction is packaging format: the substitute is supplied in Tape & Reel (TR) configuration, which is standard for high-volume production environments. Both parts satisfy ROHS3 compliance and REACH regulatory requirements, with MSL Level 1 moisture sensitivity classification suitable for standard storage and handling conditions.

Frequently Asked Questions (FAQ)

Q: Can DS1814AR-10+T&R directly replace DS1814AR-10/T&R in existing designs?

A: Yes. Both parts are electrically and mechanically identical. The substitute maintains the same voltage threshold (4.375V), output configuration (push-pull, totem-pole), reset timeout (140ms minimum), operating temperature range (-40°C to 85°C), and SOT-23-5 package specification. No circuit modifications are required.

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

A: The primary difference is packaging format. DS1814AR-10/T&R uses standard tube or tray packaging, while DS1814AR-10+T&R is supplied in Tape & Reel (TR) format. Additionally, DS1814AR-10+T&R carries Active product status with higher inventory availability, whereas DS1814AR-10/T&R is classified as Obsolete.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and classified as MSL Level 1 (Unlimited moisture sensitivity). Regulatory and environmental compliance is identical.

Q: Is the SOT-23-5 package compatible with existing PCB layouts?

A: Yes. Both parts use the SC-74A, SOT-753 package designation. PCB footprints, land patterns, and assembly processes remain unchanged. Surface-mount assembly equipment compatibility is maintained.

Q: What is the recommended part for new procurement?

A: DS1814AR-10+T&R is recommended for new designs and ongoing procurement due to Active product status and standard Tape & Reel packaging format suitable for production environments.
