DS1818-5 Equivalent & Substitute Parts

Part Overview

The DS1818-5 is a single-channel supervisor IC from Analog Devices Inc./Maxim Integrated's EconoReset series, designed for power management and reset signal generation in electronic systems. 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 DS1818-5 is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DS1818-5 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 output
• Reset Timeout: 100ms Minimum
• Operating Temperature Range: -40°C to 85°C
• Package / Case: TO-226-3 or TO-92-3 (TO-226AA) through-hole mounting
• Functional Classification: Simple Reset/Power-On Reset supervisor

The DS1818-5+ is identified as a direct substitute based on identical electrical specifications, threshold voltage, output configuration, reset timing, and package form factor. The primary distinction is product status and compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The DS1818-5+ is the direct functional equivalent of the DS1818-5 supervisor IC. Both devices share identical electrical specifications, threshold voltage, output configuration, reset timing characteristics, and through-hole package form factor.

The DS1818-5+ is recommended for new designs and ongoing system support due to its active product status and ROHS3 compliance certification. The DS1818-5, classified as obsolete, is no longer recommended for new applications.

For systems currently using the DS1818-5, the DS1818-5+ provides a pin-compatible, electrically equivalent replacement without circuit modification. Both devices maintain REACH Unaffected status and identical export classification (EAR99).

Frequently Asked Questions (FAQ)

Q: Are the DS1818-5 and DS1818-5+ pin-compatible?

A: Yes. Both devices use the TO-92-3 (TO-226AA) through-hole package with identical pinout and electrical specifications. Direct substitution is possible without PCB modification.

Q: What is the primary difference between DS1818-5 and DS1818-5+?

A: The DS1818-5+ is an active product with ROHS3 compliance certification, while the DS1818-5 is obsolete and RoHS non-compliant. Electrical performance and package form factor are identical.

Q: Can the DS1818-5+ be used in legacy systems designed for DS1818-5?

A: Yes. The DS1818-5+ is a direct functional replacement with identical voltage threshold (3.06V), output configuration (open drain/open collector), reset logic (active low), and reset timeout (100ms minimum). No circuit redesign is required.

Q: What is the voltage threshold for this supervisor IC?

A: The voltage threshold is 3.06V for single-channel monitoring. This threshold applies to both the DS1818-5 and DS1818-5+.

Q: What is the reset output configuration?

A: Both devices provide an open drain or open collector output with active-low reset logic and a minimum reset timeout of 100ms.

Q: Are there any compliance differences between the two parts?

A: The DS1818-5+ is ROHS3 compliant, while the DS1818-5 is RoHS non-compliant. Both maintain REACH Unaffected status and identical export classification (EAR99).

Q: What is the operating temperature range?

A: Both the DS1818-5 and DS1818-5+ operate across -40°C to 85°C ambient temperature range (TA).
