DS1834A Equivalent & Substitute Parts

Part Overview

The DS1834A is a multi-voltage supervisor IC from Analog Devices Inc./Maxim Integrated, designed for power management applications requiring dual-channel voltage monitoring. This device monitors two voltage thresholds (3.3V and 5V) and provides active-low reset output via open drain or open collector configuration. The DS1834A is classified as obsolete, making identification of compatible substitute parts essential for ongoing system support and component procurement.

Substitute Part Grouping Explanation

Substitution of the DS1834A is determined by strict equivalence across the following critical parameters:

• Voltage Monitoring Channels: Must support 2-channel configuration
• Voltage Thresholds: Must match 3.3V and 5V monitoring levels
• Output Type: Must provide open drain or open collector output
• Reset Behavior: Must implement active-low reset logic with 200ms minimum timeout
• Operating Temperature Range: Must support -40°C to 85°C operation
• Package Configuration: Must use 8-DIP through-hole package (0.300", 7.62mm)
• Electrical Characteristics: Must maintain functional equivalence across all specified parameters

The DS1834+ meets all substitution criteria as a parametric equivalent, differing only in packaging format (tube vs. unspecified) and RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

The DS1834+ serves as a direct parametric equivalent to the DS1834A across all functional and electrical specifications. Both devices are classified as obsolete products from the same manufacturer series (EconoReset).

The primary distinction between these parts is RoHS compliance status: the DS1834A is RoHS non-compliant, while the DS1834+ achieves RoHS3 compliance. For applications subject to RoHS regulatory requirements or environmental compliance mandates, the DS1834+ is the appropriate selection. For legacy systems or applications without RoHS constraints, either part maintains functional equivalence.

Both parts carry identical REACH and ECCN classifications (REACH Unaffected, EAR99), indicating equivalent regulatory treatment for export and environmental compliance purposes.

Frequently Asked Questions (FAQ)

Q: Can the DS1834+ directly replace the DS1834A in existing designs?

A: Yes. The DS1834+ is a parametric equivalent with identical electrical specifications, voltage thresholds, output configuration, reset behavior, operating temperature range, and 8-DIP package dimensions. Direct substitution is supported without circuit modification.

Q: What is the difference between DS1834A and DS1834+?

A: The devices are functionally identical. The DS1834+ differs in packaging format (tube) and RoHS compliance status (RoHS3 compliant vs. non-compliant). All electrical and functional parameters remain equivalent.

Q: Are there any compatibility concerns with the 8-DIP through-hole package?

A: No. Both the DS1834A and DS1834+ use identical 8-DIP (0.300", 7.62mm) through-hole packages. PCB footprints and mounting procedures are interchangeable.

Q: Does the RoHS3 compliance of DS1834+ affect circuit performance?

A: No. RoHS compliance status reflects manufacturing process and material composition standards, not functional performance. The DS1834+ maintains identical electrical characteristics and operating specifications as the DS1834A.

Q: What voltage thresholds does this supervisor monitor?

A: The DS1834A and DS1834+ both monitor two voltage channels at 3.3V and 5V thresholds with active-low reset output and 200ms minimum reset timeout.
