DS1810-10+ Equivalent & Substitute Parts

Part Overview

The DS1810-10+ is a single-channel power supply supervisor IC manufactured by Analog Devices Inc./Maxim Integrated, part of the EconoReset series. This device provides simple reset and power-on reset functionality with push-pull totem pole output configuration. The supervisor monitors a single voltage threshold at 4.37V and delivers an active-low reset signal with a 100ms minimum timeout. The DS1810-10+ is actively produced and ROHS3 compliant, making it suitable for applications requiring reliable power management and system initialization control. Equivalent and substitute parts are identified when they maintain compatibility across critical electrical and mechanical parameters while meeting the same regulatory and compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the DS1810-10+ is determined by alignment across the following critical parameters:

• Voltage Threshold: The monitored voltage level must match or remain within acceptable tolerance (4.37V ± tolerance)
• Output Configuration: Push-pull totem pole output is required for direct functional replacement
• Reset Logic: Active-low reset signal is mandatory
• Reset Timeout: Minimum timeout specification must be met or exceeded
• Operating Temperature Range: Must cover -40°C to 85°C minimum
• Package / Case: TO-92-3 (TO-226AA) through-hole package required for mechanical compatibility
• Regulatory Compliance: ROHS3 compliance and REACH unaffected status required

The MCP100-450DI/TO manufactured by Microchip Technology meets these substitution criteria. Both devices operate as single-channel supervisors with push-pull totem pole outputs, active-low reset logic, and identical package specifications. The voltage threshold differential (4.37V vs. 4.375V) and reset timeout variation (100ms vs. 150ms) remain within acceptable engineering tolerances for supervisor IC applications.

Parameter Comparison

Engineering Selection Recommendations

Both the DS1810-10+ and MCP100-450DI/TO are active production devices with full ROHS3 compliance and REACH unaffected status, making them suitable for current and future applications. Selection between these parts should be based on:

• Availability and Lead Time: The MCP100-450DI/TO currently maintains higher inventory levels (18,213 pcs vs. 1,400 pcs), which may impact procurement timelines.
• Voltage Threshold Tolerance: The 0.005V difference (4.37V vs. 4.375V) is negligible for most power management applications and falls within standard supervisor IC tolerances.
• Reset Timeout Specification: The MCP100-450DI/TO provides a 150ms minimum timeout compared to the DS1810-10+ 100ms specification. Applications with strict timing requirements should account for this 50ms difference.
• Packaging Format: Both devices are supplied in TO-92-3 through-hole packages with identical mechanical compatibility.
• Regulatory Alignment: Both parts meet identical compliance requirements (ROHS3, REACH unaffected, EAR99 classification).

Frequently Asked Questions (FAQ)

Q: Can the MCP100-450DI/TO directly replace the DS1810-10+ in existing designs?

A: Yes. Both devices share identical package specifications (TO-92-3), 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 engineering tolerances for supervisor IC applications.

Q: What is the significance of the voltage threshold difference between these parts?

A: The DS1810-10+ monitors 4.37V while the MCP100-450DI/TO monitors 4.375V. This 0.005V difference is negligible and falls within standard component tolerances. Both thresholds are suitable for 5V supply rail supervision.

Q: How does the reset timeout difference affect circuit operation?

A: The DS1810-10+ provides a 100ms minimum reset timeout, while the MCP100-450DI/TO provides 150ms. The longer timeout in the MCP100 allows additional system stabilization time during power-on sequences. Applications with timing-critical initialization should account for this difference during design validation.

Q: Are both parts suitable for new designs?

A: Yes. Both the DS1810-10+ and MCP100-450DI/TO are active production devices with current regulatory compliance (ROHS3, REACH unaffected). Either part is appropriate for new product development.

Q: What packaging considerations apply to these supervisor ICs?

A: Both parts use TO-92-3 through-hole packages (TO-226AA designation). This package type requires through-hole PCB mounting and is not suitable for surface-mount applications. Mechanical compatibility is identical between both parts.

Q: Do these parts have different moisture sensitivity requirements?

A: No. Both devices carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage or handling.
