DS1813-5 Equivalent & Substitute Parts

Part Overview

The DS1813-5 is a supervisor integrated circuit from Analog Devices Inc./Maxim Integrated's EconoReset series, designed for power management and reset control applications. This component monitors a single voltage channel and provides active-low reset output through an open-drain or open-collector configuration. The DS1813-5 is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. Functionally equivalent alternatives are available from both Analog Devices and third-party manufacturers, offering improved product status and compliance certifications.

Substitute Part Grouping Explanation

Substitution eligibility for the DS1813-5 is determined by the following critical parameters:

Single voltage channel monitoring capability
Voltage threshold of 4.62V (±0.005V tolerance acceptable)
Open-drain or open-collector output configuration
Active-low reset logic
Reset timeout minimum of 100ms
Through-hole mounting in TO-92-3 package
Operating temperature range of -40°C to 85°C

Substitute parts are grouped into three categories based on their relationship to the main part:

Direct Packaging Variants (DS1813-5+, DS1813-5+T&R): Identical electrical specifications with different packaging formats (bulk versus cut tape). These parts maintain full compatibility with the original design.

Parametric Equivalent (DS1811-5+): Same base electrical characteristics and package configuration, representing an alternative part number within the same product family.

Cross-Manufacturer Equivalent (MCP130-475DI/TO): Functionally equivalent supervisor from Microchip Technology with matching electrical parameters and package type, though with a slightly higher reset timeout specification (150ms minimum versus 100ms minimum).

Engineering Selection Recommendations

For Direct Replacement in Active Production: DS1813-5+ or DS1813-5+T&R are the preferred choices. Both maintain identical electrical specifications to the original part while offering active product status and ROHS3 compliance. Selection between these two depends on packaging requirements: DS1813-5+ for bulk applications, DS1813-5+T&R for cut-tape automated assembly processes.

For Parametric Equivalence Within Analog Devices Portfolio: DS1811-5+ provides an alternative part number with matching electrical characteristics and active status. This option is suitable when DS1813-5+ availability is constrained, as inventory levels for DS1811-5+ are significantly higher (156,752 units in stock).

For Cross-Manufacturer Substitution: MCP130-475DI/TO from Microchip Technology is functionally equivalent with ROHS3 compliance and active product status. The reset timeout specification of 150ms minimum (versus 100ms minimum for Analog Devices parts) is acceptable for applications where the extended timeout does not conflict with system requirements. This option provides supply chain diversification.

All substitute parts maintain compliance with REACH regulations and carry EAR99 export classification. Moisture sensitivity level remains at MSL 1 (unlimited) across all options.

Frequently Asked Questions (FAQ)

Q: Can DS1813-5+ be used as a direct replacement for DS1813-5?

A: Yes. DS1813-5+ is electrically and mechanically identical to DS1813-5, with the primary difference being product status (active versus obsolete) and RoHS compliance (ROHS3 compliant versus non-compliant). Pin configuration, voltage threshold, output type, and package remain unchanged.

Q: What is the difference between DS1813-5+ and DS1813-5+T&R?

A: Both parts have identical electrical specifications. The difference is packaging format: DS1813-5+ is supplied in bulk, while DS1813-5+T&R is supplied in cut tape (CT) format with formed leads. Cut tape packaging is optimized for automated pick-and-place assembly processes.

Q: Is DS1811-5+ a suitable substitute for DS1813-5?

A: Yes. DS1811-5+ meets all critical electrical parameters: single voltage channel monitoring, 4.62V threshold, open-drain output, active-low reset, 100ms minimum timeout, and TO-92-3 package. The primary difference is the base part number (DS1811 versus DS1813), which does not affect functional compatibility.

Q: Can MCP130-475DI/TO replace DS1813-5 in all applications?

A: MCP130-475DI/TO is functionally equivalent with one specification difference: reset timeout is 150ms minimum instead of 100ms minimum. This part is suitable for applications where the extended reset timeout does not create timing conflicts. Voltage threshold (4.625V) is within acceptable tolerance of the DS1813-5 specification (4.62V).

Q: Are all substitute parts RoHS compliant?

A: DS1813-5+ and DS1813-5+T&R are ROHS3 compliant. DS1811-5+ is also ROHS3 compliant. MCP130-475DI/TO is ROHS3 compliant. The original DS1813-5 is RoHS non-compliant.

Q: What is the moisture sensitivity level for these parts?

A: All parts, including the original DS1813-5 and all substitutes, carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.

Q: Are there any export restrictions on these parts?

A: All parts are classified as EAR99 and carry REACH Unaffected status, indicating standard export classification with no additional regulatory restrictions.
