MAX813LESA-T Equivalent & Substitute Parts

Part Overview

The MAX813LESA-T is a supervisor integrated circuit from Analog Devices Inc./Maxim Integrated, classified as a Power Management (PMIC) device. It functions as a simple reset/power-on reset supervisor with push-pull, totem pole output configuration, monitoring a single voltage channel at 4.65V threshold. The device is currently listed as obsolete product status. Due to its obsolete classification, identifying equivalent and substitute parts is necessary for ongoing system maintenance, redesign efforts, and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MAX813LESA-T are identified based on strict parameter matching across the following critical criteria:

Electrical Parameters:

• Single voltage channel monitoring capability
• 4.65V voltage threshold
• Push-pull, totem pole output configuration
• Active high reset logic
• 140ms minimum reset timeout
• Operating temperature range: -40°C to 85°C

Mechanical & Physical Parameters:

• 8-SOIC package form factor (0.154", 3.90mm width)
• Surface mount mounting type

Compliance & Environmental:

• RoHS3 compliance
• MSL 1 (Unlimited) moisture sensitivity level

Substitute parts are grouped into two categories: direct manufacturer equivalents and parametric equivalents. Direct equivalents maintain identical electrical and mechanical specifications with different packaging or product status. Parametric equivalents provide functionally equivalent performance across all critical operating parameters while potentially originating from different manufacturers.

Parameter Comparison

Engineering Selection Recommendations

MAX813LESA+T (Direct Manufacturer Equivalent)

This part is the direct equivalent to MAX813LESA-T from the same manufacturer, Analog Devices Inc./Maxim Integrated. The primary distinction is product status: MAX813LESA+T is active, whereas MAX813LESA-T is obsolete. All electrical, mechanical, and compliance parameters are identical. The packaging differs only in format designation (Cut Tape & Digi-Reel® versus the original specification). This part is the preferred selection for direct replacement when active inventory is required.

SP813LEN-L/TR (Manufacturer Recommended Equivalent)

The SP813LEN-L/TR from MaxLinear, Inc. is designated as a manufacturer-recommended equivalent. It maintains all critical electrical parameters: single voltage monitoring, 4.65V threshold, active high reset, 140ms minimum timeout, and identical operating temperature range. The 8-SOIC package and surface mount configuration are preserved. Product status is active with confirmed inventory availability. Output configuration is not specified in the provided data. RoHS compliance is confirmed. This part represents a cross-manufacturer alternative with active product status.

STM805LM6F (Parametric Equivalent)

The STM805LM6F from STMicroelectronics is a parametric equivalent meeting all specified electrical and mechanical requirements. It provides identical voltage threshold (4.65V), reset logic (active high), reset timeout (140ms minimum), and operating temperature range (-40°C to 85°C). The push-pull, totem pole output configuration matches the original specification. The 8-SOIC package and surface mount mounting are identical. Product status is active with confirmed inventory. RoHS3 compliance and MSL 1 rating are maintained. This part is suitable for applications where cross-manufacturer sourcing is acceptable.

Frequently Asked Questions (FAQ)

Q: Can MAX813LESA+T be used as a direct replacement for MAX813LESA-T?

A: Yes. MAX813LESA+T is electrically and mechanically identical to MAX813LESA-T. The only difference is product status (active versus obsolete) and packaging format. All functional parameters, threshold voltage, reset timing, output configuration, and package form factor are identical.

Q: What is the primary difference between the three substitute parts?

A: MAX813LESA+T is a direct equivalent from the same manufacturer with identical specifications. SP813LEN-L/TR is a manufacturer-recommended equivalent from MaxLinear with all critical parameters matched but from a different manufacturer. STM805LM6F is a parametric equivalent from STMicroelectronics that meets all electrical and mechanical specifications. All three are active products with confirmed inventory.

Q: Are all substitute parts compatible with the original 8-SOIC PCB footprint?

A: Yes. All substitute parts use the 8-SOIC package (0.154", 3.90mm width) with surface mount configuration, maintaining compatibility with the original PCB layout and assembly process.

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

A: All substitute parts are RoHS compliant and maintain MSL 1 (Unlimited) moisture sensitivity level. MAX813LESA+T and STM805LM6F are ROHS3 compliant. SP813LEN-L/TR is RoHS compliant. All meet the compliance requirements for the original application.

Q: What is the voltage threshold specification, and do all parts match?

A: The voltage threshold is 4.65V for single-channel monitoring. All substitute parts maintain this identical threshold specification, ensuring equivalent supervisory function across power supply monitoring applications.

Q: Is the reset timeout specification identical across all parts?

A: Yes. All substitute parts specify 140ms minimum reset timeout with active high reset logic, maintaining identical power-on reset timing behavior as the original MAX813LESA-T.
