DS1817-10+ Equivalent & Substitute Parts

Part Overview

The DS1817-10+ is a single-channel power supply supervisor IC manufactured by Analog Devices Inc./Maxim Integrated, designed for simple reset and power-on reset applications. This component monitors a single voltage rail and provides push-pull, totem pole output with active high reset signaling. The DS1817-10+ 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 for the DS1817-10+ is determined by the following critical parameters:

• Functional Type: Single-channel supervisor with simple reset/power-on reset capability
• Output Configuration: Push-pull, totem pole output with active high reset logic
• Voltage Monitoring: Single voltage rail monitoring capability
• Package Compatibility: TO-92-3 (TO-226-3) through-hole package
• Operating Temperature Range: -40°C ~ 85°C
• Regulatory Compliance: ROHS3 compliant, REACH unaffected

The MCP101-300DI/TO from Microchip Technology meets these substitution criteria. Both parts share identical functional architecture, output configuration, package form factor, and regulatory compliance status. The MCP101-300DI/TO is currently in active production status, providing long-term availability for replacement and new designs.

Parameter Comparison

Engineering Selection Recommendations

The MCP101-300DI/TO is the qualified substitute for the obsolete DS1817-10+. Both components are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The MCP101-300DI/TO maintains active production status, ensuring availability for replacement applications and new designs.

The voltage threshold differential (2.88V versus 2.925V) and reset timeout variation (100ms minimum versus 150ms minimum) represent the measurable parameter differences between these parts. System design must account for these specifications during component selection to ensure proper reset behavior and voltage monitoring performance.

Frequently Asked Questions (FAQ)

Q: Can the MCP101-300DI/TO directly replace the DS1817-10+ without PCB modifications?

A: Yes. Both parts use identical TO-92-3 through-hole packaging and share the same pinout configuration for push-pull, totem pole output with active high reset logic. No PCB layout changes are required for physical substitution.

Q: What are the key differences between these two supervisor ICs?

A: The primary differences are voltage threshold (2.88V for DS1817-10+ versus 2.925V for MCP101-300DI/TO) and reset timeout specification (100ms minimum versus 150ms minimum). The MCP101-300DI/TO is currently in active production, while the DS1817-10+ is obsolete.

Q: Are both parts compliant with current environmental and regulatory standards?

A: Yes. Both the DS1817-10+ and MCP101-300DI/TO are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.

Q: What is the operating temperature range for both parts?

A: Both supervisor ICs operate across the temperature range of -40°C to 85°C (TA), providing equivalent thermal performance for industrial and commercial applications.

Q: Is the MCP101-300DI/TO available in the same packaging as the DS1817-10+?

A: Yes. The MCP101-300DI/TO is supplied in TO-226-3, TO-92-3 (TO-226AA) through-hole packaging, identical to the DS1817-10+.
