ADM810LART-REEL Equivalent & Substitute Parts

Part Overview

The ADM810LART-REEL is a single-channel power management supervisor IC manufactured by Analog Devices Inc., housed in a SOT-23-3 surface mount package. This device functions as a simple reset/power-on reset supervisor with push-pull totem pole output, designed to monitor supply voltage and generate reset signals for microprocessor and system applications.

The ADM810LART-REEL is classified as obsolete. Equivalent and substitute parts are necessary to maintain design continuity and ensure component availability for new production runs, repairs, and system upgrades where the original part is no longer readily available from primary sources.

Substitute Part Grouping Explanation

Substitute parts for the ADM810LART-REEL are classified into two categories based on electrical and mechanical compatibility:

Direct Equivalents share identical electrical specifications and packaging, differing only in product status or packaging format (reel configuration). These parts are interchangeable without design modification.

Parametric Equivalents maintain all critical electrical parameters—voltage threshold (4.63V), output configuration (push-pull totem pole), reset logic (active high), reset timeout (140ms minimum), and package type (SOT-23-3)—but may vary in operating temperature range or reset timeout specification. These parts function identically in the target application.

Key Substitution Parameters:

Voltage Threshold: 4.63V (mandatory match)
Output Configuration: Push-Pull, Totem Pole (mandatory match)
Reset Logic: Active High (mandatory match)
Package Type: SOT-23-3 (mandatory match)
Reset Timeout: 140ms Minimum (preferred match)
Operating Temperature Range: -40°C to 125°C (preferred match)

Engineering Selection Recommendations

Primary Recommendation: ADM810LARTZ-REEL or ADM810LARTZ-REEL7

These Analog Devices parts are direct equivalents to the ADM810LART-REEL with identical electrical specifications and operating temperature range (-40°C to 125°C). Both are active products with ROHS3 compliance and unlimited moisture sensitivity rating. ADM810LARTZ-REEL7 offers higher inventory availability (24,821 units) compared to ADM810LARTZ-REEL (1,779 units).

Secondary Recommendation: LM810M3-4.63/NOPB (Texas Instruments)

This part maintains all critical electrical parameters and reset timeout specification (140ms minimum). Operating temperature range is reduced to -40°C to 105°C. ROHS3 compliant with active product status. Suitable for applications not requiring the full -40°C to 125°C temperature range.

Alternative Recommendations: MAX810LEUR+T, MAX810LEUR+T10, MIC810LUY-TR, STM810LWX6F, TCM810LENB713

These parts provide functional equivalence with matching voltage threshold, output configuration, reset logic, and reset timeout. Operating temperature ranges vary between -40°C to 85°C and -40°C to 105°C. All are active products with ROHS3 compliance. Selection depends on specific thermal requirements and supply chain availability.

Not Recommended for Direct Substitution: MAX6347UR46+T, MAX6800UR46D3+T

These parts feature reduced reset timeout specification (100ms minimum versus 140ms minimum). While electrically compatible in voltage threshold and output configuration, the shorter reset timeout may affect system reset behavior in timing-sensitive applications. Use only if application timing requirements permit the reduced timeout specification.

Frequently Asked Questions (FAQ)

Q: Can ADM810LARTZ-REEL directly replace ADM810LART-REEL?

A: Yes. ADM810LARTZ-REEL is a direct equivalent with identical electrical specifications, voltage threshold (4.63V), output configuration (push-pull totem pole), reset logic (active high), reset timeout (140ms minimum), and operating temperature range (-40°C to 125°C). The primary difference is product status (active versus obsolete) and packaging format (tape and reel configuration).

Q: What is the difference between ADM810LARTZ-REEL and ADM810LARTZ-REEL7?

A: Both parts are electrically identical with matching specifications. ADM810LARTZ-REEL7 includes an additional suffix designation. Inventory availability differs significantly, with ADM810LARTZ-REEL7 offering substantially higher stock levels (24,821 units versus 1,779 units).

Q: Can I use MAX6347UR46+T or MAX6800UR46D3+T as substitutes?

A: These parts share the same voltage threshold (4.63V), output configuration (push-pull totem pole), reset logic (active high), and SOT-23-3 package. However, reset timeout is specified at 100ms minimum instead of 140ms minimum. Use these parts only if your application timing requirements accommodate the shorter reset timeout specification.

Q: Are all substitute parts ROHS3 compliant?

A: All active substitute parts listed are ROHS3 compliant. The original ADM810LART-REEL (obsolete) does not specify RoHS status in available documentation.

Q: What is the operating temperature difference between substitute options?

A: The ADM810LART-REEL operates from -40°C to 125°C. Substitute parts vary: ADM810LARTZ-REEL and ADM810LARTZ-REEL7 match this range; LM810M3-4.63/NOPB and MAX810LEUR variants operate to 105°C; MIC810LUY-TR, STM810LWX6F, TCM810LENB713, and MAX6347UR46+T operate to 85°C. Select based on your application's thermal environment.

Q: Do all substitute parts use the same SOT-23-3 package?

A: Yes. All listed substitute parts use the SOT-23-3 package (also designated TO-236-3 or SC-59), ensuring mechanical and electrical compatibility with the original ADM810LART-REEL footprint.

Q: Which substitute offers the best inventory availability?

A: ADM810LARTZ-REEL7 (Analog Devices Inc.) offers the highest inventory with 24,821 units in stock, followed by TCM810LENB713 (Microchip Technology) with 38,600 units. Both maintain full electrical equivalence to the original part.
