DS1830AS Equivalent & Substitute Parts

Part Overview

The DS1830AS is a 3-channel supervisor IC manufactured by Analog Devices Inc./Maxim Integrated, designed for power management applications requiring voltage monitoring and sequencing control. This device operates as an open drain or open collector output supervisor with active low reset functionality, housed in an 8-SOIC surface mount package.

The DS1830AS is classified as obsolete, which necessitates identification of functionally equivalent alternatives for new designs or ongoing production requirements. Active substitute parts maintain identical electrical and mechanical specifications while offering current product status and improved compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DS1830AS is determined by strict equivalence across the following critical parameters:

• Voltage Monitoring Channels: 3 channels (non-negotiable for functional compatibility)
• Voltage Threshold Setting: 3.3V (determines circuit protection level)
• Output Type: Open Drain or Open Collector (defines interface compatibility)
• Reset Configuration: Active Low with specified timeout values (10ms, 20ms, 50ms minimum)
• Package and Pinout: 8-SOIC surface mount (ensures PCB compatibility)
• Operating Temperature Range: -40°C to 85°C (defines environmental suitability)

The DS1830AS+ is a direct substitute that maintains all electrical and mechanical specifications while offering active product status and improved regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The DS1830AS+ is the direct functional equivalent for applications currently using the DS1830AS. Selection of the DS1830AS+ is justified by the following factors:

Product Status: The DS1830AS+ maintains active product status, ensuring continued availability and manufacturer support. The DS1830AS is obsolete and subject to supply discontinuation.

Regulatory Compliance: The DS1830AS+ achieves ROHS3 compliance, meeting current environmental and hazardous substance restrictions. This compliance status is required for new designs and many production environments.

Electrical and Mechanical Equivalence: All functional parameters—voltage monitoring channels, threshold settings, output configuration, reset logic, operating temperature range, and package specifications—are identical between the two parts.

Packaging: The DS1830AS+ is supplied in tube packaging, which is standard for active production components and facilitates automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the DS1830AS+ be used as a direct replacement for the DS1830AS in existing designs?

A: Yes. The DS1830AS+ is electrically and mechanically equivalent to the DS1830AS. All functional parameters, including voltage monitoring channels, threshold settings, output configuration, reset logic, and package specifications, are identical. No circuit modifications are required.

Q: What is the difference between the DS1830AS and DS1830AS+?

A: The primary differences are product status and regulatory compliance. The DS1830AS is obsolete, while the DS1830AS+ is active. The DS1830AS+ achieves ROHS3 compliance, whereas the DS1830AS is RoHS non-compliant. Electrical and mechanical specifications are identical.

Q: Are there any package or pinout differences between these parts?

A: No. Both parts use the 8-SOIC surface mount package with identical pinout and dimensions (0.154", 3.90mm width). PCB layouts and assembly processes require no modification.

Q: Why is the DS1830AS obsolete?

A: Obsolescence is determined by the manufacturer. The DS1830AS+ is the active replacement that maintains full functional equivalence while meeting current regulatory requirements.

Q: What is the significance of ROHS3 compliance on the DS1830AS+?

A: ROHS3 compliance indicates that the DS1830AS+ meets current restrictions on hazardous substances in electrical and electronic equipment. This certification is required for many applications and markets. The DS1830AS, being non-compliant, may not be suitable for new designs or regulated environments.

Q: Can I mix DS1830AS and DS1830AS+ parts in the same production batch?

A: While electrically equivalent, mixing obsolete and active parts is not recommended for production consistency. Use the DS1830AS+ for all new production to ensure supply continuity and regulatory compliance.
