DS1812-5 Equivalent & Substitute Parts

Part Overview

The DS1812-5 is a supervisor integrated circuit from Analog Devices Inc./Maxim Integrated's EconoReset series, designed for power management and reset control applications. This single-channel power-on reset supervisor features push-pull totem pole output configuration and operates across industrial temperature ranges. The DS1812-5 is classified as obsolete, making equivalent and substitute parts necessary for ongoing system support and new design implementations. Substitute parts maintain functional equivalence through matching electrical specifications and mechanical compatibility while offering active product status and improved compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DS1812-5 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Single-channel voltage monitoring configuration
• Voltage threshold tolerance within 4.62V ± 0.005V specification
• Push-pull totem pole output stage
• Active high reset logic
• Reset timeout minimum of 100ms or greater
• Operating temperature range of -40°C to 85°C or wider

Mechanical Equivalence Criteria:

• Through-hole mounting type
• TO-92-3 package compatibility (TO-226-3, TO-226AA variants)
• Pin-compatible footprint

Compliance Considerations:

• RoHS3 compliance preferred for new designs
• MSL rating of 1 (Unlimited) maintained across all substitutes
• REACH and ECCN classifications consistent

The substitute parts DS1812-5+, DS1812-5+T&R, and MCP101-475DI/TO meet these criteria while offering active product status and improved regulatory compliance compared to the obsolete DS1812-5.

Parameter Comparison

Engineering Selection Recommendations

DS1812-5+ and DS1812-5+T&R (Analog Devices Inc./Maxim Integrated)

These parts provide direct functional equivalence to the DS1812-5 with identical electrical specifications and mechanical compatibility. Both variants achieve ROHS3 compliance and active product status. Selection between these two depends on packaging requirements: DS1812-5+ is supplied in bulk packaging, while DS1812-5+T&R is supplied in cut tape format with formed leads. For applications requiring long-term supply chain stability and regulatory compliance, these Analog Devices variants are the primary substitutes.

MCP101-475DI/TO (Microchip Technology)

This cross-manufacturer substitute maintains electrical and mechanical equivalence with one specification variance: the reset timeout is specified at 150ms minimum compared to 100ms for the DS1812-5. This extended timeout is functionally compatible with applications designed for the DS1812-5 and does not represent a functional limitation. The MCP101-475DI/TO achieves ROHS3 compliance and active product status. This option provides supply diversification through an alternative manufacturer while maintaining pin-compatible TO-92-3 packaging.

All three substitute parts maintain identical operating temperature ranges, output configurations, and package compatibility with the obsolete DS1812-5, enabling direct replacement in existing designs.

Frequently Asked Questions (FAQ)

Q: Can DS1812-5+ directly replace DS1812-5 in existing designs?

A: Yes. DS1812-5+ maintains identical electrical specifications, output configuration, and TO-92-3 package compatibility. The primary difference is improved RoHS3 compliance status and active product availability. Pin-for-pin replacement is supported without circuit modifications.

Q: What is the difference between DS1812-5+ and DS1812-5+T&R?

A: Both parts are electrically identical. The difference is packaging format: DS1812-5+ is supplied in bulk, while DS1812-5+T&R is supplied in cut tape with formed leads. Selection depends on assembly process requirements and volume handling procedures.

Q: Is MCP101-475DI/TO compatible with DS1812-5 applications?

A: Yes. MCP101-475DI/TO provides functional equivalence with identical voltage threshold, output configuration, and package compatibility. The reset timeout specification is 150ms minimum versus 100ms for DS1812-5. This extended timeout is compatible with applications designed for the original part and does not create functional incompatibility.

Q: What is the voltage threshold tolerance between DS1812-5 and MCP101-475DI/TO?

A: DS1812-5 specifies 4.62V threshold; MCP101-475DI/TO specifies 4.625V threshold. This 0.005V difference is within typical application tolerances for power-on reset supervisors and does not affect functional compatibility in standard circuit implementations.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. DS1812-5+ and DS1812-5+T&R are ROHS3 compliant. MCP101-475DI/TO is also ROHS3 compliant. The original DS1812-5 is RoHS non-compliant, making the substitutes necessary for applications requiring regulatory compliance.

Q: Can these parts be used interchangeably in production?

A: DS1812-5+ and DS1812-5+T&R are fully interchangeable from an electrical and mechanical standpoint. MCP101-475DI/TO is also interchangeable with the noted reset timeout specification difference. All three maintain identical TO-92-3 package compatibility and through-hole mounting requirements.

Q: What is the MSL rating for these supervisor ICs?

A: All parts, including the original DS1812-5 and all substitutes, carry MSL rating of 1 (Unlimited), indicating no moisture sensitivity limitations for storage and handling.
