Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the DS1233M-55+ is determined by strict alignment across the following critical parameters:

• Voltage Threshold: 4.625V (single-channel monitoring requirement)
• Output Configuration: Open Drain or Open Collector topology
• Reset Logic: Active Low operation
• Reset Timeout: 200ms Minimum specification
• Operating Temperature Range: -40°C ~ 85°C (TA)
• Package Type: TO-92-3 (TO-226AA) through-hole configuration
• Regulatory Compliance: ROHS3 Compliant, REACH Unaffected status

The DS1233M-55+ serves as both the primary reference part and the direct substitute within this equivalency group. No alternative part numbers have been identified that maintain identical electrical and mechanical specifications across all critical parameters while preserving functional compatibility in reset/power-on reset applications.

Parameter Comparison

Engineering Selection Recommendations

The DS1233M-55+ maintains Active product status from Analog Devices Inc./Maxim Integrated, confirming current manufacturing availability and ongoing technical support. The device carries ROHS3 Compliant certification and REACH Unaffected regulatory status, meeting contemporary environmental and compliance requirements for industrial and commercial applications.

Component selection should prioritize the DS1233M-55+ as the primary choice for new designs and procurement activities. The part's Active status, combined with verified regulatory compliance and established supply chain presence (2300 Pcs New Original In Stock), ensures design continuity and long-term availability. The TO-92-3 through-hole package configuration supports both legacy and contemporary PCB assembly methodologies.

Frequently Asked Questions (FAQ)

Q: What defines a valid substitute for the DS1233M-55+?

A: A valid substitute must maintain identical specifications across voltage threshold (4.625V), output configuration (Open Drain or Open Collector), reset logic (Active Low), reset timeout (200ms Minimum), operating temperature range (-40°C ~ 85°C), and package type (TO-92-3). Regulatory compliance status (ROHS3, REACH) must also align.

Q: Can the DS1233M-55+ be replaced with alternative supervisor ICs from other manufacturers?

A: Substitution with parts from alternative manufacturers is not supported based on the provided parameter set. Cross-manufacturer substitution requires verification of identical electrical characteristics, package compatibility, and regulatory certifications beyond the scope of this equivalency reference.

Q: Is the TO-92-3 package interchangeable with other package variants?

A: The TO-92-3 (TO-226AA) package is the specified configuration for this application. Package variants such as surface-mount alternatives or different pin counts introduce mechanical and electrical incompatibilities and are not considered equivalent substitutes.

Q: What is the significance of the 4.625V voltage threshold specification?

A: The 4.625V threshold defines the supply voltage monitoring point at which the supervisor triggers reset signaling. This parameter is application-specific and cannot be altered through substitution. Alternative parts must maintain this exact threshold value.

Q: Does ROHS3 compliance affect substitution eligibility?

A: Yes. Both the main part and any substitute must maintain ROHS3 Compliant status to ensure regulatory alignment in target markets. Non-compliant alternatives are not acceptable substitutes.
