DS1811-5 Equivalent & Substitute Parts

Part Overview

The DS1811-5 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 open drain or open collector output with active low reset functionality and a 4.62V voltage threshold. The DS1811-5 is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing production requirements. Substitute parts maintain identical or compatible electrical and mechanical specifications while offering active product status and improved availability.

Substitute Part Grouping Explanation

Substitution eligibility for the DS1811-5 is determined by the following critical parameters: single-channel voltage monitoring, 4.62V threshold voltage, open drain or open collector output configuration, active low reset logic, through-hole TO-92-3 package compatibility, and compliance certifications (ROHS3, REACH Unaffected).

Substitute parts are grouped into three categories:

Direct Manufacturer Equivalents (Packaging Variants): DS1811-5+ and DS1811-5+T&R are identical electrical and functional equivalents from the same manufacturer, differing only in packaging format (Bulk and Cut Tape respectively). Both maintain active product status and full parameter compatibility.

Parametric Equivalent: DS1813-5+ is a variant within the same EconoReset series with identical electrical specifications and package compatibility. This part maintains active product status and serves as a direct functional replacement.

Cross-Manufacturer Equivalent: MCP130-475DI/TO from Microchip Technology provides equivalent functionality with compatible electrical parameters. The reset timeout specification differs (150ms minimum versus 100ms minimum), representing the only parametric variance among all substitutes.

Engineering Selection Recommendations

For new designs and production transitions from the obsolete DS1811-5, the DS1811-5+ or DS1811-5+T&R are the primary recommendations. Both parts are direct manufacturer equivalents with active product status, identical electrical specifications, and full compliance certifications. Selection between these two depends on packaging requirements: DS1811-5+ for bulk applications and DS1811-5+T&R for cut tape automated assembly processes.

The DS1813-5+ serves as an alternative within the same EconoReset series, maintaining identical electrical and mechanical compatibility with active product status and equivalent compliance certifications.

The MCP130-475DI/TO from Microchip Technology is a cross-manufacturer equivalent suitable for applications where supply chain diversification is required. This part maintains all critical electrical parameters with the exception of reset timeout specification (150ms minimum versus 100ms minimum for Analog Devices parts). This variance must be evaluated against specific application timing requirements.

All substitute parts maintain ROHS3 compliance, REACH unaffected status, and MSL 1 rating, ensuring regulatory and environmental compatibility with the original DS1811-5 specification.

Frequently Asked Questions (FAQ)

Q: Can DS1811-5+ be used as a direct replacement for DS1811-5?

A: Yes. DS1811-5+ is a direct manufacturer equivalent with identical electrical specifications, voltage threshold, output configuration, and package compatibility. The primary difference is product status (active versus obsolete) and packaging format (bulk).

Q: What is the difference between DS1811-5+T&R and DS1811-5+?

A: Both parts are electrically identical. DS1811-5+T&R is supplied in cut tape format with formed leads, suitable for automated pick-and-place assembly. DS1811-5+ is supplied in bulk packaging. Selection depends on assembly process requirements.

Q: Is DS1813-5+ compatible with DS1811-5 applications?

A: Yes. DS1813-5+ maintains identical electrical specifications, voltage threshold (4.62V), output type (open drain or open collector), reset logic (active low), and package compatibility (TO-92-3). Both are part of the EconoReset series.

Q: Can MCP130-475DI/TO replace DS1811-5 in all applications?

A: MCP130-475DI/TO is functionally equivalent with compatible electrical parameters and package compatibility. The reset timeout specification differs (150ms minimum versus 100ms minimum). Applications with strict reset timing requirements must evaluate this variance against design specifications.

Q: Are all substitute parts RoHS and REACH compliant?

A: Yes. All substitute parts listed (DS1811-5+, DS1811-5+T&R, DS1813-5+, and MCP130-475DI/TO) are ROHS3 compliant and REACH unaffected, matching the original DS1811-5 compliance status.

Q: What package options are available for DS1811-5 substitutes?

A: All substitute parts use the same through-hole TO-92-3 package (TO-226-3, TO-226AA designation). DS1811-5+T&R includes formed leads for automated assembly compatibility.

Q: Why is the DS1811-5 obsolete?

A: The DS1811-5 is classified as obsolete by the manufacturer. Active equivalent parts (DS1811-5+, DS1813-5+) are available for new designs and production transitions.
