Engineering Selection Recommendations

MIC1810-5UY-TR is the direct Microchip Technology equivalent with identical electrical specifications and SOT-23-3 packaging. This part is currently active in production and ROHS3 compliant, addressing the RoHS non-compliance status of the discontinued MIC1810-5U-TR. Inventory availability is 791 pieces.

DS1810R-5+T&R is the manufacturer-recommended alternative from Analog Devices Inc./Maxim Integrated, part of the EconoReset series. This part meets all threshold, reset, and temperature specifications. The DS1810R-5+T&R features push-pull totem pole output configuration and is ROHS3 compliant. Inventory availability is 4300 pieces, providing superior supply continuity.

Both substitute parts maintain electrical equivalence through identical voltage threshold (4.62V), reset polarity (active low), reset timeout (100ms minimum), and operating temperature range (-40°C to 85°C). Package compatibility is confirmed across all three parts in SOT-23-3 form factor.

Frequently Asked Questions (FAQ)

Q: Can MIC1810-5UY-TR directly replace MIC1810-5U-TR in existing designs?

A: Yes. MIC1810-5UY-TR is electrically and mechanically identical to MIC1810-5U-TR. Both parts share the same 4.62V threshold, active-low reset output, 100ms timeout, and SOT-23-3 package. The primary difference is product status (active vs. discontinued) and RoHS compliance level.

Q: What is the functional difference between MIC1810-5UY-TR and DS1810R-5+T&R?

A: Both parts are functionally equivalent for single-channel 4.62V threshold monitoring with active-low reset output. The DS1810R-5+T&R specifies push-pull totem pole output, while the MIC1810-5UY-TR output specification is not detailed. Both meet the 100ms minimum reset timeout and -40°C to 85°C operating range.

Q: Are there packaging differences between the substitute parts?

A: MIC1810-5U-TR and MIC1810-5UY-TR are supplied in Tape & Reel (TR) packaging. DS1810R-5+T&R is supplied in Cut Tape (CT) & Digi-Reel® packaging. All three parts use identical SOT-23-3 component packaging for PCB mounting.

Q: Which substitute part should be selected for new production?

A: Selection depends on supply chain requirements and compliance mandates. MIC1810-5UY-TR maintains Microchip Technology sourcing with 791 pieces in stock. DS1810R-5+T&R provides higher inventory (4300 pieces) and is manufacturer-recommended, supporting extended production runs and supply security.

Q: Are all three parts ROHS3 compliant?

A: MIC1810-5U-TR is RoHS non-compliant. Both MIC1810-5UY-TR and DS1810R-5+T&R are ROHS3 compliant. For applications requiring RoHS compliance, either substitute part is acceptable.

Q: Do all parts share the same moisture sensitivity level?

A: Yes. MIC1810-5U-TR, MIC1810-5UY-TR, and DS1810R-5+T&R all have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions for storage and handling.
