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 active-low reset functionality with a 4.62V threshold and 100ms minimum reset timeout. The device is classified as Active product status with full ROHS3 compliance and unlimited moisture sensitivity rating. Equivalent and substitute parts are identified when designs require alternative sourcing, inventory optimization, or packaging format changes while maintaining identical electrical and mechanical specifications.

Key Parameters

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, active-low reset output, open drain/open collector configuration, 100ms minimum reset timeout, through-hole TO-92-3 package mounting, -40°C to 85°C operating temperature range, and ROHS3 compliance status.

Parts are grouped into three categories:

Direct Equivalent (Packaging Variant): DS1811-5+T&R maintains identical electrical specifications and threshold voltage but differs in packaging format (Cut Tape versus Bulk). This variant is suitable for automated assembly processes requiring tape-and-reel delivery.

Parametric Equivalent (Same Series): DS1813-5+ shares all critical electrical parameters including voltage threshold, reset timeout, output type, and operating temperature range. Both devices belong to the EconoReset series and are manufactured by Analog Devices Inc./Maxim Integrated with identical compliance certifications.

Cross-Manufacturer Equivalent: MCP130-475DI/TO from Microchip Technology provides functional equivalence with matching voltage threshold (4.625V), active-low reset, open drain output, and TO-92-3 package. The reset timeout specification (150ms minimum) exceeds the DS1811-5+ requirement, maintaining backward compatibility in applications.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain Active product status with full ROHS3 and REACH compliance, ensuring regulatory alignment with the original DS1811-5+ specification.

DS1811-5+T&R is selected when procurement requires cut-tape packaging for automated pick-and-place assembly operations. Electrical performance is identical to bulk packaging; the distinction is delivery format only.

DS1813-5+ is selected for equivalent functionality within the Analog Devices EconoReset product line. Threshold voltage, reset timeout, and output characteristics are identical, supporting direct functional replacement in existing designs.

MCP130-475DI/TO from Microchip Technology is selected when cross-manufacturer sourcing is required. The 150ms reset timeout exceeds the DS1811-5+ minimum specification of 100ms, providing additional timing margin in applications where extended reset duration is acceptable. Voltage threshold tolerance (4.625V) is within acceptable substitution parameters for single-channel supervision applications.

Frequently Asked Questions (FAQ)

Q: Can DS1811-5+T&R be used as a direct replacement for DS1811-5+ in production assembly?

A: Yes. DS1811-5+T&R is electrically and mechanically identical to DS1811-5+. The T&R designation indicates cut-tape packaging format suitable for automated assembly. Both variants share identical threshold voltage (4.62V), reset timeout (100ms minimum), and TO-92-3 package specifications. Selection depends on assembly process requirements, not electrical compatibility.

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

A: Yes. DS1813-5+ maintains all critical electrical parameters: 4.62V threshold voltage, 100ms minimum reset timeout, active-low reset output, and open drain configuration. Both devices operate across -40°C to 85°C and are housed in TO-92-3 packages. The devices are functionally interchangeable within the EconoReset series.

Q: What is the difference between DS1811-5+ and MCP130-475DI/TO?

A: Both devices provide single-channel voltage supervision with active-low reset and open drain output in TO-92-3 packages. The primary difference is reset timeout specification: MCP130-475DI/TO specifies 150ms minimum versus DS1811-5+ at 100ms minimum. The MCP130 threshold voltage is 4.625V compared to 4.62V for the DS1811. These differences are within acceptable substitution parameters for applications where extended reset timing is compatible with system requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. DS1811-5+, DS1811-5+T&R, DS1813-5+, and MCP130-475DI/TO are all ROHS3 compliant with REACH Unaffected status, meeting current environmental and regulatory requirements.

Q: Can MCP130-475DI/TO be used in applications requiring exactly 100ms reset timeout?

A: MCP130-475DI/TO specifies 150ms minimum reset timeout, which exceeds the DS1811-5+ requirement of 100ms minimum. Applications requiring precisely 100ms timing should use DS1811-5+, DS1811-5+T&R, or DS1813-5+. Applications tolerant of longer reset delays can use MCP130-475DI/TO.

Q: What packaging formats are available for DS1811-5+ equivalents?

A: DS1811-5+ is available in Bulk packaging. DS1811-5+T&R is available in Cut Tape (CT) format with formed leads for automated assembly. DS1813-5+ is available in Bulk packaging. MCP130-475DI/TO is available in Bag packaging. Selection depends on procurement and assembly process requirements.
