Key Parameters

Substitute Part Grouping Explanation

Substitution of the MIC1815-10U-TR is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Single channel voltage monitoring capability
• 2.88V threshold voltage
• Push-pull totem pole output configuration
• Active low reset logic
• 100ms minimum reset timeout
• Single supply voltage operation

Mechanical Equivalence Criteria:

• SOT-23-3 package (TO-236-3, SC-59)
• Surface mount technology
• MSL 1 (Unlimited) moisture sensitivity

Compliance Considerations:

• RoHS compliance status
• REACH compliance status
• Product availability and active status

The substitute parts identified maintain full electrical and mechanical compatibility with the original MIC1815-10U-TR, enabling direct replacement in existing designs and new applications requiring this supervisor IC topology.

Parameter Comparison

Engineering Selection Recommendations

ADM1815-10ARTZ-RL7 (Analog Devices Inc.) is the manufacturer-recommended substitute. This part maintains full electrical and mechanical equivalence to the MIC1815-10U-TR while offering extended operating temperature range (-40°C ~ 105°C versus -40°C ~ 85°C) and ROHS3 compliance. Active product status ensures long-term availability and supply chain continuity. This option is preferred for new designs and applications requiring regulatory compliance.

DS1815R-10+T&R (Analog Devices Inc./Maxim Integrated) is a parametric equivalent classified within the EconoReset series. This part provides identical electrical functionality and operating temperature range matching the original MIC1815-10U-TR. ROHS3 compliance and active product status support ongoing system requirements. This option is suitable for applications where the extended temperature capability of the ADM1815 variant is not required.

Both substitute parts are actively manufactured and stocked, providing reliable alternatives to the discontinued MIC1815-10U-TR for immediate component replacement and future procurement.

Frequently Asked Questions (FAQ)

Q: Can the ADM1815-10ARTZ-RL7 be used as a direct replacement for the MIC1815-10U-TR?

A: Yes. The ADM1815-10ARTZ-RL7 maintains identical electrical specifications (2.88V threshold, push-pull totem pole output, active low reset, 100ms timeout) and mechanical compatibility (SOT-23-3 package, surface mount). The extended operating temperature range (-40°C ~ 105°C) provides additional capability without affecting compatibility.

Q: What is the difference between the ADM1815-10ARTZ-RL7 and DS1815R-10+T&R?

A: Both parts are electrically equivalent to the MIC1815-10U-TR. The primary difference is operating temperature range: ADM1815-10ARTZ-RL7 operates to 105°C, while DS1815R-10+T&R operates to 85°C (matching the original). Packaging differs: ADM1815 is supplied in Tape & Reel, while DS1815R is supplied in Cut Tape & Digi-Reel®.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both ADM1815-10ARTZ-RL7 and DS1815R-10+T&R are ROHS3 compliant, whereas the original MIC1815-10U-TR is RoHS non-compliant. This compliance upgrade supports regulatory requirements in new designs.

Q: Will the substitute parts fit the existing PCB layout designed for MIC1815-10U-TR?

A: Yes. Both substitute parts use the identical SOT-23-3 package (TO-236-3, SC-59) with the same pinout and footprint as the MIC1815-10U-TR, enabling direct PCB compatibility without layout modifications.

Q: What is the moisture sensitivity level of the substitute parts?

A: Both substitute parts maintain MSL 1 (Unlimited) moisture sensitivity, identical to the original MIC1815-10U-TR. No special moisture handling or baking procedures are required.

Q: Are both substitute parts currently in stock?

A: Yes. ADM1815-10ARTZ-RL7 has 6100 pieces in stock, and DS1815R-10+T&R has 6001 pieces in stock, both listed as new original inventory with active product status.
