DS1811-10 Equivalent & Substitute Parts

Part Overview

The DS1811-10 is a single-channel power supply supervisor IC from Analog Devices Inc./Maxim Integrated, part of the EconoReset series. This through-hole mounted component provides reset and power-on reset functionality with an open drain or open collector output configuration. The DS1811-10 is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing production requirements. Substitute parts must maintain identical electrical characteristics and mechanical compatibility to ensure direct replacement capability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DS1811-10 is determined by the following critical parameters: single-channel voltage monitoring, 4.35V threshold voltage, open drain or open collector output, active low reset logic, 100ms minimum reset timeout, through-hole mounting in TO-92-3 package, and operating temperature range of -40°C to 85°C.

Substitute parts are grouped into three categories:

Direct Packaging Equivalents: DS1811-10+ (bulk packaging) and DS1811-10+T&R (cut tape packaging) are identical to the main part with identical electrical specifications and differ only in packaging format and product status (active versus obsolete).

Parametric Equivalents: DS1813-10+ maintains all critical electrical parameters and mechanical compatibility, including voltage threshold, output configuration, reset logic, and package type, with identical reset timeout and operating temperature specifications.

Cross-Manufacturer Equivalent: MCP130-450DI/TO from Microchip Technology provides functional equivalence with identical output configuration, reset logic, package type, and operating temperature range. This part exhibits a marginally higher voltage threshold (4.375V versus 4.35V) and extended reset timeout (150ms versus 100ms minimum), which remain within acceptable substitution parameters for most applications.

Parameter Comparison

Engineering Selection Recommendations

For new designs and production applications, DS1811-10+ or DS1811-10+T&R are the primary substitutes, offering identical electrical specifications with active product status and ROHS3 compliance. DS1811-10+T&R provides the highest inventory availability (4,460 units) in cut tape packaging format suitable for automated assembly processes.

DS1813-10+ serves as a parametric equivalent with identical critical specifications and active product status, offering 2,332 units in inventory. This part is suitable for applications where the DS1811-10+ is unavailable.

MCP130-450DI/TO from Microchip Technology is a cross-manufacturer equivalent with active product status and ROHS3 compliance. The marginally higher voltage threshold (4.375V) and extended reset timeout (150ms) are functionally compatible with the original specification. This part provides 2,754 units in inventory and represents an alternative source for supply chain diversification.

All substitute parts maintain identical package geometry (TO-92-3), mounting type (through-hole), and operating temperature range, ensuring direct mechanical and electrical compatibility in existing circuit designs.

Frequently Asked Questions (FAQ)

Q: Can DS1811-10+ be used as a direct replacement for DS1811-10?

A: Yes. DS1811-10+ is electrically and mechanically identical to DS1811-10, differing only in packaging format (bulk versus original) and product status (active versus obsolete). Both parts share identical voltage threshold, output configuration, reset logic, and package specifications.

Q: What is the difference between DS1811-10+T&R and DS1811-10+?

A: Both parts are electrically identical with identical specifications. DS1811-10+T&R is supplied in cut tape (CT) packaging format suitable for automated pick-and-place assembly, while DS1811-10+ is supplied in bulk packaging. DS1811-10+T&R offers higher inventory availability (4,460 units versus 1,371 units).

Q: Is DS1813-10+ compatible with DS1811-10?

A: Yes. DS1813-10+ maintains all critical electrical parameters including voltage threshold (4.35V), output configuration, reset logic, reset timeout (100ms minimum), and package type (TO-92-3). Both parts are functionally equivalent for circuit applications.

Q: Can MCP130-450DI/TO replace DS1811-10 in all applications?

A: MCP130-450DI/TO is functionally compatible with identical output configuration, reset logic, package type, and operating temperature range. The voltage threshold is marginally higher (4.375V versus 4.35V) and reset timeout is extended (150ms versus 100ms minimum). These differences remain within acceptable substitution parameters for most applications but should be evaluated for timing-critical circuits.

Q: What is the significance of RoHS compliance for substitute selection?

A: DS1811-10 is RoHS non-compliant, while all substitute parts (DS1811-10+, DS1811-10+T&R, DS1813-10+, and MCP130-450DI/TO) are ROHS3 compliant. For applications subject to RoHS regulations or environmental compliance requirements, substitute parts are mandatory.

Q: Are all substitute parts available in the same TO-92-3 package?

A: Yes. All substitute parts are supplied in TO-92-3 package (TO-226-3, TO-226AA designation), ensuring identical mechanical compatibility and through-hole mounting capability with the original DS1811-10.
