DS1232LPU/T&R Equivalent & Substitute Parts

Part Overview

The DS1232LPU/T&R 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 configurable voltage monitoring and output control. The part is currently listed as obsolete, making identification of compatible substitutes essential for ongoing system support and new design implementations. The supervisor operates across a 0°C to 70°C temperature range and is housed in an 8-TSSOP/8-MSOP surface mount package.

Substitute Part Grouping Explanation

Substitution for the DS1232LPU/T&R is determined by strict equivalence across the following critical parameters:

• Functional Type: Single-channel supervisor with reset/power-on reset capability
• Voltage Monitoring: 1 channel with 4.37V and 4.62V threshold support
• Output Configuration: Open Drain and Push-Pull output options
• Reset Logic: Active High/Active Low selectable reset
• Reset Timeout: Adjustable/Selectable timeout functionality
• Package Compatibility: 8-TSSOP/8-MSOP surface mount form factor
• Temperature Range: 0°C to 70°C operating specification
• Electrical Characteristics: Identical voltage thresholds and output behavior

The DS1232LPU+T&R meets all substitution criteria as a direct equivalent, differing only in packaging format (Tape & Reel versus individual unit packaging) and product status classification.

Parameter Comparison

Engineering Selection Recommendations

The DS1232LPU+T&R is a direct functional equivalent to the DS1232LPU/T&R. Both parts share identical electrical specifications, voltage thresholds, output configurations, and package dimensions. The primary distinction is product status: the main part is obsolete while the substitute is active in production.

For new designs and ongoing system support, the DS1232LPU+T&R is the appropriate selection. This part maintains full electrical and mechanical compatibility while offering the advantage of active product status and ROHS3 compliance, compared to the RoHS non-compliant status of the obsolete variant. Both parts carry identical REACH and ECCN classifications, and both feature unlimited moisture sensitivity level (MSL 1).

The packaging difference (Tape & Reel format for the substitute) is a logistics consideration rather than a functional distinction and does not affect circuit-level performance or pin compatibility.

Frequently Asked Questions (FAQ)

Q: Can DS1232LPU+T&R be used as a direct replacement for DS1232LPU/T&R in existing designs?

A: Yes. Both parts are electrically and mechanically identical. They share the same voltage thresholds (4.37V, 4.62V), output configurations (Open Drain, Push-Pull), reset logic options (Active High/Active Low), and package form factor (8-TSSOP/8-MSOP). Pin-for-pin compatibility is complete.

Q: What is the difference between DS1232LPU/T&R and DS1232LPU+T&R?

A: The parts differ in packaging format and product lifecycle status. DS1232LPU/T&R is obsolete and RoHS non-compliant. DS1232LPU+T&R is active in production and ROHS3 compliant. The "+T&R" designation indicates Tape & Reel packaging, a standard format for high-volume manufacturing and automated assembly.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts operate identically across all specified parameters: single-channel voltage monitoring, 4.37V and 4.62V threshold levels, adjustable/selectable reset timeout, and 0°C to 70°C operating temperature range.

Q: Does the Tape & Reel packaging affect circuit performance?

A: No. Tape & Reel is a packaging and delivery format used for automated assembly processes. The die, electrical characteristics, and functional behavior are identical to other packaging formats of the same part number.

Q: What compliance certifications apply to both parts?

A: Both parts are REACH Unaffected and classified as EAR99 for export control purposes. The substitute (DS1232LPU+T&R) is ROHS3 compliant, while the main part (DS1232LPU/T&R) is RoHS non-compliant. Both have unlimited moisture sensitivity level (MSL 1).
