Key Parameters

Substitute Part Grouping Explanation

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

• Voltage Threshold: 3.06V (single channel monitoring)
• Output Type: Open Drain or Open Collector configuration
• Reset Logic: Active Low
• Reset Timeout: 100ms Minimum
• Package: TO-92-3 (TO-226AA) through-hole mounting
• Operating Temperature: -40°C ~ 85°C (TA)
• Regulatory Compliance: ROHS3 Compliant, REACH Unaffected

The DS1818-5+ meets all specified parameters and serves as a direct parametric equivalent. Both devices share identical electrical characteristics, package specifications, and regulatory compliance status, with the primary distinction being product lifecycle status.

Parameter Comparison

Engineering Selection Recommendations

The DS1818-5+ is the appropriate substitute for the obsolete DS1816-5+. Both components are manufactured by Analog Devices Inc./Maxim Integrated and maintain identical electrical specifications, package configurations, and regulatory compliance certifications. The DS1818-5+ carries active product status, ensuring continued availability and supply chain support. Both devices comply with ROHS3 requirements and are REACH unaffected, meeting current environmental and regulatory standards. The through-hole TO-92-3 package format remains consistent between both parts, allowing direct board-level substitution without layout modifications.

Frequently Asked Questions (FAQ)

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

A: Yes. The DS1818-5+ is a parametric equivalent with identical voltage threshold (3.06V), output configuration (open drain/open collector), reset logic (active low), reset timeout (100ms minimum), operating temperature range (-40°C ~ 85°C), and package specification (TO-92-3). Both devices are ROHS3 compliant and REACH unaffected.

Q: What is the primary difference between these two parts?

A: The DS1816-5+ is classified as obsolete, while the DS1818-5+ maintains active product status. All electrical and mechanical specifications are identical.

Q: Are there any package or pinout differences?

A: No. Both the DS1816-5+ and DS1818-5+ use the TO-92-3 (TO-226AA) through-hole package with identical pinout and mechanical dimensions.

Q: Does the DS1818-5+ meet the same regulatory requirements?

A: Yes. The DS1818-5+ is ROHS3 compliant and REACH unaffected, matching the compliance profile of the DS1816-5+.

Q: What inventory status should be considered when selecting between these parts?

A: The DS1818-5+ has 2200 pieces in stock, providing superior availability compared to the DS1816-5+, which is obsolete. For new designs and ongoing production, the DS1818-5+ is the recommended selection.
