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 functionality. This device operates as a push-pull, totem pole output supervisor with active-low reset control and a 100ms minimum reset timeout. The DS1810-5+ is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DS1810-5+ is determined by strict alignment of the following critical parameters:

• Single-channel voltage monitoring capability with push-pull, totem pole output configuration
• Voltage threshold specification within acceptable tolerance (4.62V nominal)
• Active-low reset logic with minimum reset timeout of 100ms or greater
• TO-92-3 package compatibility for through-hole mounting
• Operating temperature range of -40°C to 85°C or wider
• Regulatory compliance including ROHS3 and REACH status

The MCP100-475DI/TO from Microchip Technology meets all substitution criteria. This device maintains functional equivalence through identical output topology, reset logic, package form factor, and thermal operating range. The voltage threshold variance (4.625V vs. 4.62V) falls within standard engineering tolerance for supervisor threshold specifications. The extended reset timeout (150ms minimum vs. 100ms minimum) provides additional margin and does not compromise system compatibility.

Parameter Comparison

Engineering Selection Recommendations

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

Product Status & Availability: The DS1810-5+ is obsolete, whereas the MCP100-475DI/TO maintains active product status with confirmed inventory availability (1742 pcs in stock). This ensures long-term supply chain continuity.

Regulatory Compliance: Both devices maintain ROHS3 compliance and REACH unaffected status, satisfying environmental and regulatory requirements for equivalent deployment.

Functional Equivalence: Identical electrical specifications for single-channel voltage monitoring, push-pull output topology, active-low reset logic, and operating temperature range ensure direct functional replacement without circuit redesign.

Package Compatibility: Both devices utilize the TO-92-3 through-hole package, enabling direct board-level substitution without layout modifications.

Threshold & Timing Tolerance: The voltage threshold difference (4.625V vs. 4.62V) represents a 0.11% variance, well within standard supervisor IC tolerance specifications. The increased reset timeout (150ms vs. 100ms) provides additional system stability margin.

Frequently Asked Questions (FAQ)

Q: Can the MCP100-475DI/TO directly replace the DS1810-5+ without circuit modifications?

A: Yes. Both devices share identical package form factor (TO-92-3), output topology (push-pull, totem pole), reset logic (active low), and operating temperature range (-40°C to 85°C). No circuit redesign is required for direct substitution.

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

A: The 0.005V difference represents 0.11% variance, which is within standard tolerance for supervisor threshold specifications. Both thresholds function equivalently for 5V system monitoring applications.

Q: Does the longer reset timeout (150ms vs. 100ms) affect system compatibility?

A: No. The extended reset timeout provides additional margin for system stabilization. Applications designed for 100ms minimum timeout will operate correctly with 150ms minimum timeout, as the longer duration does not compromise reset functionality.

Q: Are there any compliance or certification differences between these devices?

A: No. Both devices maintain identical ROHS3 compliance, REACH unaffected status, and MSL rating (1 - Unlimited), ensuring equivalent regulatory and environmental qualification.

Q: Why is the DS1810-5+ classified as obsolete?

A: Obsolescence reflects end-of-life status from the original manufacturer. The MCP100-475DI/TO provides active product support and ongoing availability for equivalent applications.
