DS1233Z-10 Equivalent & Substitute Parts

Part Overview

The DS1233Z-10 is a single-channel power supply supervisor IC from Analog Devices Inc./Maxim Integrated, part of the EconoReset series. This Surface Mount device operates as a Simple Reset/Power-On Reset supervisor with an open drain or open collector output configuration. The part is classified as Obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement continuity. Substitute parts maintain identical electrical and mechanical specifications while offering improved product status or packaging availability.

Substitute Part Grouping Explanation

Substitute parts for the DS1233Z-10 are identified based on strict electrical and mechanical parameter matching within the EconoReset supervisor IC category. The substitution criteria are:

• Single-channel voltage monitoring at 4.375V threshold
• Open drain or open collector output configuration
• Active low reset logic with 250ms minimum timeout
• Operating temperature range of -40°C to 85°C
• Surface mount packaging in SOT-223-3 configuration
• ROHS3 compliance and REACH unaffected status
• Identical regulatory classifications (ECCN: EAR99, HTSUS: 8542.39.0001)

Two substitute parts meet these criteria: DS1233Z-10+ (direct manufacturer part with improved product status) and DS1233DZ-10+ (parametric equivalent with alternative base product designation).

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are functionally equivalent to the DS1233Z-10 across all critical electrical and mechanical parameters. Selection between alternatives should be based on product lifecycle status and procurement requirements:

DS1233Z-10+ is the primary recommended substitute. It maintains the identical base product designation (DS1233) and carries Active product status, ensuring long-term availability and manufacturer support. This part is supplied in Tube packaging and maintains the highest inventory level at 17,648 units.

DS1233DZ-10+ serves as a parametric equivalent with identical electrical specifications and Active product status. The alternative base product designation (DS1233D) reflects a variant within the EconoReset series. This part is also supplied in Tube packaging with 3,700 units in stock.

Both substitutes comply with ROHS3 and REACH requirements, matching the regulatory profile of the original part. No additional qualification or testing is required for direct substitution in applications currently using the DS1233Z-10.

Frequently Asked Questions (FAQ)

Q: Can DS1233Z-10+ be used as a direct replacement for DS1233Z-10?

A: Yes. The DS1233Z-10+ is a direct substitute with identical electrical specifications, including 4.375V threshold voltage, active low reset logic, 250ms minimum reset timeout, and SOT-223-3 packaging. The primary difference is product status: DS1233Z-10+ is Active while DS1233Z-10 is Obsolete.

Q: What is the difference between DS1233Z-10+ and DS1233DZ-10+?

A: Both parts are parametric equivalents with identical electrical and mechanical specifications. The difference lies in the base product designation (DS1233 versus DS1233D). Both are Active status, ROHS3 compliant, and supplied in SOT-223-3 packaging. Selection may be based on inventory availability or supplier preference.

Q: Are the packaging dimensions identical across all three parts?

A: Yes. All three parts use the same supplier device package (SOT-223-3) and are classified as TO-261-4 and TO-261AA case types. They are mechanically interchangeable in Surface Mount applications.

Q: Do these substitutes require PCB layout modifications?

A: No. The DS1233Z-10+, and DS1233DZ-10+ maintain identical pinout and package footprint specifications. Existing PCB designs require no modification.

Q: Are there any compliance or certification differences?

A: No. All three parts share identical RoHS3 compliance, REACH unaffected status, and regulatory classifications (ECCN: EAR99, HTSUS: 8542.39.0001). Moisture sensitivity level is 1 (Unlimited) for all variants.

Q: Which substitute should be selected for new designs?

A: DS1233Z-10+ is recommended for new designs due to Active product status and higher inventory availability. This ensures long-term supply chain stability and manufacturer support.
