DS1813-5+ Equivalent & Substitute Parts

Part Overview

The DS1813-5+ is a single-channel power supply supervisor IC from Analog Devices Inc./Maxim Integrated, part of the EconoReset series. This through-hole mounted component provides reset and power-on reset functionality with an open drain output configuration. The device monitors a single voltage threshold at 4.62V and delivers an active-low reset signal with a 100ms minimum timeout. As an active product with ROHS3 compliance and unlimited moisture sensitivity rating, the DS1813-5+ serves critical power management applications requiring reliable supervisor functionality. Alternative equivalent parts may be required due to inventory constraints, packaging preferences, or specific application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DS1813-5+ is determined by strict alignment with the following critical parameters:

• Single voltage monitoring channel with threshold tolerance within specification
• Open drain or open collector output configuration
• Active low reset logic with minimum 100ms timeout
• Through-hole mounting in TO-92-3 package format
• Operating temperature range of -40°C to 85°C
• ROHS3 compliance and MSL Level 1 rating

Substitute parts are grouped into three categories:

Direct Equivalent (Identical Specifications): DS1813-5+ (Bulk packaging) and DS1813-5+T&R (Cut Tape packaging) share identical electrical and mechanical specifications, differing only in packaging format.

Parametric Equivalent (Same Functional Parameters): DS1811-5+ maintains all critical electrical parameters including voltage threshold, output configuration, reset logic, and timeout specifications. The base product number differs (DS1811 vs. DS1813), but functional performance is equivalent.

Manufacturer-Recommended Equivalent (Minor Parameter Variance): MCP130-475DI/TO from Microchip Technology meets all core functional requirements with a voltage threshold of 4.625V (within tolerance of 4.62V specification) and a 150ms minimum reset timeout (exceeds the 100ms minimum requirement).

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain active product status and ROHS3 compliance, ensuring continued manufacturer support and regulatory alignment.

DS1813-5+T&R is the direct equivalent to DS1813-5+ with identical electrical specifications. Selection between bulk and cut tape packaging depends on assembly process requirements and inventory management practices.

DS1811-5+ provides parametric equivalence with all critical electrical and mechanical specifications matching the DS1813-5+. This part is suitable for applications where the base product number change does not conflict with design documentation or procurement specifications.

MCP130-475DI/TO from Microchip Technology is the manufacturer-recommended equivalent. The voltage threshold of 4.625V remains within acceptable tolerance of the 4.62V specification. The 150ms reset timeout exceeds the 100ms minimum requirement, providing additional timing margin. This part is appropriate for applications where cross-manufacturer sourcing is acceptable and inventory availability is a priority.

Frequently Asked Questions (FAQ)

Q: Can DS1813-5+T&R be used as a direct replacement for DS1813-5+?

A: Yes. DS1813-5+T&R is electrically and mechanically identical to DS1813-5+. The only difference is packaging format: bulk versus cut tape. Selection depends on assembly process compatibility and supply chain requirements.

Q: Is DS1811-5+ a suitable substitute for DS1813-5+?

A: Yes. DS1811-5+ is a parametric equivalent with identical voltage threshold (4.62V), output configuration (open drain), reset logic (active low), and reset timeout (100ms minimum). The base product number differs, but functional performance is equivalent for all specified applications.

Q: Can MCP130-475DI/TO replace DS1813-5+ in production designs?

A: Yes, with engineering review. MCP130-475DI/TO meets all core functional requirements. The voltage threshold of 4.625V is within tolerance of the 4.62V specification. The 150ms reset timeout exceeds the 100ms minimum, providing additional timing margin. Cross-manufacturer substitution requires design documentation update and qualification testing per your organization's change control procedures.

Q: What are the key parameters that determine substitution compatibility?

A: Substitution compatibility is determined by: single-channel voltage monitoring, 4.62V threshold (±tolerance), open drain output configuration, active low reset logic, 100ms minimum reset timeout, through-hole mounting in TO-92-3 package, -40°C to 85°C operating temperature range, and ROHS3 compliance.

Q: Are there packaging differences between substitute parts?

A: Yes. DS1813-5+ is supplied in bulk packaging, DS1813-5+T&R in cut tape, and MCP130-475DI/TO in bag packaging. All three use the same TO-92-3 through-hole package format. Packaging selection depends on assembly equipment compatibility and inventory management practices.

Q: Do all substitute parts have the same moisture sensitivity rating?

A: Yes. All listed parts carry MSL Level 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage, handling, or assembly processes.
