DS1232LPS-2/T&R Equivalent & Substitute Parts

Part Overview

The DS1232LPS-2/T&R is a Power Management Integrated Circuit (PMIC) supervisor manufactured by Analog Devices Inc./Maxim Integrated. This device functions as a single-channel power supply supervisor with open drain and push-pull output capabilities, designed for reset and power-on reset applications. The part is classified as obsolete, making equivalent and substitute components necessary for new designs and ongoing production requirements. Substitute parts must maintain functional equivalence across voltage monitoring, output configuration, and thermal operating parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DS1232LPS-2/T&R are selected based on strict parameter equivalence across the following criteria:

Functional Parameters:

• Single-channel voltage monitoring capability
• Voltage threshold levels of 4.37V and 4.62V
• Output type compatibility (Open Drain or Open Collector configurations are functionally equivalent in supervisor applications)
• Active High/Active Low reset logic capability
• Operating temperature range of 0°C to 70°C

Physical Parameters:

• 8-SOIC package form factor (0.154", 3.90mm Width)
• Surface mount mounting type
• MSL rating of 1 (Unlimited)

Regulatory Parameters:

• ROHS3 compliance status
• REACH unaffected classification
• ECCN EAR99 export control classification
• HTSUS code 8542.39.0001

Substitutes are grouped into two categories: direct manufacturer equivalents from Analog Devices Inc./Maxim Integrated, and cross-manufacturer alternatives from Microchip Technology that meet all functional and physical requirements.

Parameter Comparison

Engineering Selection Recommendations

DS1232LPS-2+T&R (Analog Devices Inc./Maxim Integrated): This part is the direct equivalent from the original manufacturer. It maintains identical functional specifications and voltage thresholds while offering active product status and ROHS3 compliance. The packaging format differs only in tape and reel configuration (Cut Tape & Digi-Reel® versus the original format). This substitute is recommended for designs requiring manufacturer continuity and maximum parameter alignment.

TC1232COA (Microchip Technology): This cross-manufacturer substitute meets all functional requirements with identical voltage thresholds and reset logic capabilities. It is supplied in tube packaging and maintains active product status with ROHS3 compliance. The reset timeout specification differs (250ms minimum versus adjustable/selectable), which may require circuit design verification for applications with specific timeout requirements.

TC1232COA713 (Microchip Technology): This variant of the TC1232COA is supplied in Cut Tape & Digi-Reel® packaging, matching the original part's tape and reel format. It provides identical functional and compliance characteristics to the TC1232COA with the same reset timeout specification consideration.

All substitute parts comply with REACH regulations and maintain the same export control classification (EAR99) and tariff code (8542.39.0001) as the original part.

Frequently Asked Questions (FAQ)

Q: Can the DS1232LPS-2+T&R be used as a direct replacement for the DS1232LPS-2/T&R?

A: Yes. The DS1232LPS-2+T&R is functionally equivalent with identical voltage thresholds (4.37V, 4.62V), output configuration, reset logic, and operating temperature range. The primary difference is packaging format and active product status. Both parts use the same 8-SOIC package and surface mount configuration.

Q: What is the functional difference between Open Drain and Open Collector outputs?

A: In supervisor circuit applications, Open Drain and Open Collector outputs are functionally equivalent. Both configurations require external pull-up resistors and provide the same reset signal control capability. The TC1232COA series specifies "Open Drain or Open Collector" output, indicating functional compatibility with the DS1232LPS-2 series Open Drain/Push-Pull configuration.

Q: Does the TC1232COA's 250ms minimum reset timeout affect compatibility?

A: The reset timeout specification differs between part families. The DS1232LPS-2 series offers adjustable/selectable timeout, while the TC1232COA series specifies 250ms minimum. Circuit designs must verify that a 250ms minimum timeout meets application requirements before selecting the TC1232COA as a substitute.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. The DS1232LPS-2+T&R, TC1232COA, and TC1232COA713 are all ROHS3 compliant. The original DS1232LPS-2/T&R is RoHS non-compliant, making the substitute parts necessary for applications requiring RoHS compliance.

Q: What is the difference between tube and tape & reel packaging?

A: Tube packaging (TC1232COA) is suitable for lower-volume applications and manual assembly. Cut Tape & Digi-Reel® packaging (DS1232LPS-2+T&R and TC1232COA713) is optimized for automated pick-and-place assembly and higher-volume production. Both packaging formats contain identical components with the same MSL rating of 1 (Unlimited).

Q: Can these parts be used interchangeably in existing designs?

A: Yes, provided the circuit design accommodates the reset timeout specification. All parts share identical voltage thresholds, package form factor, and operating temperature range. Designs using the DS1232LPS-2/T&R can transition to any substitute part without PCB layout modifications.
