DS1816-5 Equivalent & Substitute Parts

Part Overview

The DS1816-5 is a single-channel power supply supervisor IC from Analog Devices Inc./Maxim Integrated's EconoReset series, designed for power-on reset and simple reset applications. This device monitors a single voltage threshold at 3.06V and provides an active-low reset output via open drain or open collector configuration. The DS1816-5 is classified as obsolete, making identification of compatible substitute parts essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DS1816-5 is determined by strict equivalence across the following critical parameters:

• Single voltage monitoring channel with 3.06V threshold
• Open drain or open collector output configuration
• Active-low reset logic with 100ms minimum timeout
• Through-hole mounting in TO-92-3 package
• Operating temperature range of -40°C to 85°C
• EconoReset series compatibility

The DS1818-5+ meets all these criteria and serves as a parametric equivalent. The primary distinction is product status: the DS1816-5 is obsolete while the DS1818-5+ is active, along with improved RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

The DS1818-5+ is the direct substitute for the obsolete DS1816-5. Both devices are electrically and mechanically identical across all functional parameters. Selection of the DS1818-5+ is supported by its active product status and ROHS3 compliance, which provides regulatory advantage for new designs and ongoing production. The DS1818-5+ maintains full compatibility with existing circuit designs using the DS1816-5, requiring no modifications to PCB layouts or signal routing due to identical TO-92-3 packaging and pin configuration.

Frequently Asked Questions (FAQ)

Q: Can the DS1818-5+ be used as a direct replacement for the DS1816-5 in existing designs?

A: Yes. The DS1818-5+ is a parametric equivalent with identical electrical specifications, threshold voltage, output configuration, and package type. No circuit modifications are required.

Q: What is the primary reason to transition from DS1816-5 to DS1818-5+?

A: The DS1816-5 is obsolete. The DS1818-5+ is an active product from the same manufacturer and series, ensuring continued availability and supply chain reliability. Additionally, the DS1818-5+ meets ROHS3 compliance requirements.

Q: Are the pin configurations identical between these parts?

A: Yes. Both devices use the TO-92-3 package with identical pin assignments for through-hole mounting.

Q: Does the DS1818-5+ have the same voltage threshold?

A: Yes. Both parts monitor a 3.06V threshold with active-low reset output and 100ms minimum reset timeout.

Q: What is the difference in RoHS compliance?

A: The DS1816-5 is RoHS non-compliant, while the DS1818-5+ is ROHS3 compliant. This distinction is relevant for applications subject to RoHS regulations.
