DS1832 Equivalent & Substitute Parts

Part Overview

The DS1832 is a single-channel power supply supervisor IC from Analog Devices Inc./Maxim Integrated, part of the MicroMonitor™ series. This device provides reset and power-on reset functionality with push-pull output configuration, designed for through-hole mounting in 8-DIP packages. The DS1832 is classified as obsolete, making identification of compatible substitute parts essential for ongoing system support and new design implementations where legacy compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DS1832 is determined by strict equivalence across the following critical parameters:

• Functional Type: Simple Reset/Power-On Reset supervisor with single-channel voltage monitoring
• Voltage Thresholds: 2.55V and 2.88V threshold options
• Output Stage: Push-pull configuration with active high/active low reset capability
• Reset Timing: 250ms minimum reset timeout
• Thermal Range: -40°C to 85°C operating temperature
• Package Geometry: 8-DIP (0.300", 7.62mm) through-hole form factor
• Electrical Interface: Pin-compatible 8-PDIP supplier device package

The DS1832+ qualifies as a direct substitute based on identical electrical specifications, functional behavior, and physical packaging. The primary distinction is product status and compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The DS1832+ is the direct functional and electrical equivalent of the DS1832. Selection between these parts is determined by application requirements and regulatory constraints:

DS1832+ Selection Criteria:

• New designs requiring active product support and availability
• Applications subject to RoHS3 compliance requirements
• Systems requiring long-term component supply assurance
• Designs where modern manufacturing certifications are mandatory

DS1832 Selection Criteria:

• Legacy system maintenance where original part specifications are locked
• Applications where RoHS non-compliance is not a constraint
• Existing inventory utilization in established production lines

Both parts maintain identical electrical performance, thermal characteristics, and physical form factor, ensuring direct substitution at the circuit level without design modification.

Frequently Asked Questions (FAQ)

Q: Can DS1832+ be used as a direct replacement for DS1832 in existing designs?

A: Yes. The DS1832+ is electrically and functionally identical to the DS1832. All electrical parameters, voltage thresholds, output characteristics, reset timing, and thermal specifications are equivalent. The 8-DIP through-hole package geometry is identical, enabling direct PCB substitution without layout changes.

Q: What is the primary difference between DS1832 and DS1832+?

A: The DS1832 is obsolete and RoHS non-compliant. The DS1832+ is an active product with ROHS3 compliance certification. Both devices deliver identical supervisor functionality and performance characteristics.

Q: Are there any pin configuration differences between these parts?

A: No. Both the DS1832 and DS1832+ use the 8-PDIP supplier device package with identical pinout. Pin-for-pin compatibility is guaranteed.

Q: What packaging options are available for the DS1832+?

A: The DS1832+ is supplied in tube packaging format. The DS1832 packaging format is not specified in available documentation.

Q: Can these parts be used interchangeably in high-reliability applications?

A: Interchangeability is determined by application compliance requirements. The DS1832+ meets ROHS3 and REACH compliance standards. The DS1832 does not meet current RoHS standards. Application-specific compliance requirements must be evaluated before part selection.

Q: What is the moisture sensitivity level for both parts?

A: Both the DS1832 and DS1832+ have Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without moisture control requirements.

Q: Are there inventory considerations for part selection?

A: The DS1832 has 3345 pieces in stock as new original inventory. The DS1832+ has 2400 pieces in stock. Long-term availability is assured only for the DS1832+ due to its active product status.
