DS1810-5 Equivalent & Substitute Parts

Part Overview

The DS1810-5 is a supervisor integrated circuit from Analog Devices Inc./Maxim Integrated, designed for power management applications requiring single-channel voltage monitoring and reset signal generation. This device operates as a push-pull, totem pole output supervisor with active-low reset functionality, housed in a TO-92-3 package for through-hole mounting.

The DS1810-5 is classified as obsolete. Identifying suitable substitute components is necessary to maintain design continuity, ensure supply chain reliability, and support ongoing production or maintenance requirements for systems utilizing this supervisor IC.

Substitute Part Grouping Explanation

Substitution eligibility for the DS1810-5 is determined by the following critical parameters:

Mandatory Matching Criteria:

Single-channel voltage monitoring capability
Push-pull, totem pole output configuration
Active-low reset logic
TO-92-3 package (through-hole mounting)
Operating temperature range of -40°C to 85°C or wider
Voltage threshold within acceptable tolerance of 4.62V

Acceptable Variation Ranges:

Voltage threshold: ±0.005V tolerance (4.615V to 4.625V acceptable)
Reset timeout: May exceed 100ms minimum specification (150ms acceptable)
RoHS compliance: Substitute may be RoHS-compliant despite original being non-compliant
Product status: Active or equivalent status preferred over obsolete

The MCP100-475DI/TO from Microchip Technology meets all mandatory criteria and acceptable variation ranges, qualifying it as a direct substitute for the DS1810-5.

Engineering Selection Recommendations

The MCP100-475DI/TO is the qualified substitute for the DS1810-5 based on the following factors:

Functional Equivalence: Both devices provide identical single-channel voltage monitoring with push-pull, totem pole output and active-low reset logic. The voltage threshold differential of 0.005V (4.62V vs. 4.625V) is within acceptable engineering tolerance for supervisor IC applications.

Package Compatibility: Both components use the TO-92-3 package with through-hole mounting, ensuring direct PCB compatibility without layout modifications.

Reset Timing: The MCP100-475DI/TO specifies a 150ms minimum reset timeout, which exceeds the DS1810-5 specification of 100ms. This longer timeout provides additional margin in power-on reset sequencing and does not compromise system functionality.

Product Status and Compliance: The MCP100-475DI/TO is active and ROHS3-compliant, providing supply chain continuity and regulatory compliance advantages over the obsolete, non-compliant DS1810-5.

Environmental and Regulatory Alignment: Both devices share identical operating temperature ranges (-40°C to 85°C), moisture sensitivity levels (MSL 1), REACH status, and ECCN classifications, ensuring no additional regulatory or environmental constraints.

Frequently Asked Questions (FAQ)

Q: Can the MCP100-475DI/TO be used as a direct replacement for the DS1810-5 without PCB modifications?

A: Yes. Both devices use the TO-92-3 package with identical pin configurations and through-hole mounting. No PCB layout changes are required for substitution.

Q: What is the significance of the voltage threshold difference (4.62V vs. 4.625V)?

A: The 0.005V difference represents a 0.11% variance and is within standard engineering tolerance for supervisor IC applications. Both thresholds monitor the same voltage rail and trigger reset at functionally equivalent points.

Q: Why does the MCP100-475DI/TO have a longer reset timeout (150ms vs. 100ms)?

A: The extended timeout provides additional margin during power-on sequencing. This does not negatively impact system performance and is acceptable for applications designed around the DS1810-5 specification.

Q: Is the MCP100-475DI/TO RoHS-compliant?

A: Yes. The MCP100-475DI/TO is ROHS3-compliant, whereas the DS1810-5 is non-compliant. This compliance status is advantageous for new designs and regulatory requirements.

Q: Are there any electrical performance differences between these devices?

A: Both devices provide identical output configuration (push-pull, totem pole), reset logic (active low), and operating temperature range (-40°C to 85°C). The voltage threshold and reset timeout variations are within acceptable substitution parameters.

Q: What is the inventory status of the substitute part?

A: The MCP100-475DI/TO has 1742 pieces in new original stock, providing reliable supply availability compared to the obsolete DS1810-5.
