DS1233-5+ Equivalent & Substitute Parts

Part Overview

The DS1233-5+ is a single-channel power supply supervisor IC from Analog Devices Inc./Maxim Integrated, part of the EconoReset series. This through-hole mounted component monitors a single voltage rail and provides active-low reset output via open drain or open collector configuration. The device is classified as Active product status with full RoHS3 compliance and REACH unaffected designation. Substitute parts are identified when equivalent electrical parameters and mechanical compatibility are maintained across the same functional category.

Engineering Selection Recommendations

DS1233D-5+ (Parametric Equivalent): This part maintains identical electrical specifications and package compatibility with the DS1233-5+. Both are manufactured by Analog Devices Inc./Maxim Integrated within the EconoReset series. Selection between these two is based on inventory availability and supplier device package designation. Both carry Active product status with full RoHS3 and REACH compliance.

MCP130-475FI/TO (Manufacturer-Recommended Substitute): This Microchip Technology component provides cross-manufacturer substitution with equivalent electrical parameters across all critical specifications. The reset timeout of 150ms minimum is shorter than the DS1233-5+ specification of 250ms minimum, which may be advantageous in applications requiring faster reset response. All compliance certifications (RoHS3, REACH unaffected) and operating temperature range match the primary part. Package and mounting type are identical.

Selection among these three parts should be based on:

Inventory availability and lead time requirements
Supplier preference and pricing
Reset timeout requirements for the specific application circuit
Compliance documentation requirements for end-use certification

Frequently Asked Questions (FAQ)

Q: Can DS1233D-5+ be used as a direct replacement for DS1233-5+?

A: Yes. Both parts share identical electrical parameters including voltage threshold (4.625V), reset logic (active low), reset timeout (250ms minimum), and operating temperature range (-40°C ~ 85°C). Package and mounting type are equivalent. Both are Active status products with RoHS3 compliance.

Q: What is the key difference between DS1233-5+ and MCP130-475FI/TO?

A: The primary difference is the reset timeout specification. DS1233-5+ specifies 250ms minimum, while MCP130-475FI/TO specifies 150ms minimum. All other electrical parameters, package type, and compliance certifications are equivalent. The MCP130-475FI/TO is manufactured by Microchip Technology rather than Analog Devices Inc./Maxim Integrated.

Q: Are all three parts pin-compatible?

A: Yes. All three parts use the TO-92-3 package (TO-226-3, TO-226AA designation) with through-hole mounting. Pin configuration and electrical interface are compatible for direct board-level substitution.

Q: Do all substitute parts meet the same compliance requirements?

A: Yes. DS1233-5+, DS1233D-5+, and MCP130-475FI/TO all carry RoHS3 compliance, REACH unaffected status, and Moisture Sensitivity Level 1 (Unlimited). All are Active product status.

Q: Which part should be selected if reset timeout is critical to the application?

A: If the application requires the longer 250ms minimum reset timeout, select DS1233-5+ or DS1233D-5+. If faster reset response is acceptable or required, MCP130-475FI/TO with 150ms minimum timeout is suitable.

Q: Can these parts be used interchangeably in production?

A: Yes, provided the reset timeout specification of the selected part meets application requirements. All three parts are functionally equivalent for single-channel voltage monitoring with active-low reset output in the specified operating temperature range.
