MAX813LCSA Equivalent & Substitute Parts

Part Overview

The MAX813LCSA is a Power Management Integrated Circuit (PMIC) supervisor manufactured by Analog Devices Inc./Maxim Integrated. It functions as a simple reset/power-on reset supervisor with push-pull, totem pole output configuration for single-channel voltage monitoring applications. The device is classified as obsolete, which necessitates identification of functionally equivalent substitute components for ongoing design support and procurement continuity. Active alternative parts are available from multiple manufacturers with compatible electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MAX813LCSA are qualified based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• Single-channel voltage monitoring capability
• Voltage threshold of 4.65V ± tolerance
• Push-pull, totem pole output configuration
• Active high reset logic
• 140ms minimum reset timeout
• 8-SOIC surface mount package (0.154", 3.90mm width)
• Moisture Sensitivity Level 1 (Unlimited)

Secondary Considerations:

• Operating temperature range (extended range preferred for design margin)
• Product status (active status preferred over obsolete)
• RoHS compliance status
• Regulatory compliance (REACH, ECCN)

The following parts meet the primary compatibility criteria and are therefore qualified as direct substitutes:

1. MAX813LCSA+ (Analog Devices Inc./Maxim Integrated) – Direct manufacturer variant with identical electrical specifications and active product status
2. STM813LM6F (STMicroelectronics) – Cross-manufacturer equivalent with 4.63V threshold (within tolerance) and extended operating temperature range
3. SP813LEN-L/TR (MaxLinear, Inc.) – Manufacturer-recommended alternative with matching 4.65V threshold and extended operating temperature range

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Same Manufacturer): MAX813LCSA+ is the primary recommendation for direct substitution. It maintains identical electrical specifications and package configuration while offering active product status and ROHS3 compliance. This part provides the most straightforward design continuity path.

For Cross-Manufacturer Substitution: STM813LM6F (STMicroelectronics) and SP813LEN-L/TR (MaxLinear, Inc.) are qualified alternatives. Both parts offer extended operating temperature ranges (-40°C to 85°C) compared to the original specification (0°C to 70°C), providing additional thermal margin for industrial and extended-temperature applications. Both are ROHS3 compliant and carry active product status.

Compliance Considerations: All substitute parts offer improved regulatory compliance compared to the obsolete MAX813LCSA. The original part is RoHS non-compliant; all substitutes are RoHS3 compliant. This compliance improvement is significant for new designs and procurement in regulated markets.

Voltage Threshold Tolerance: STM813LM6F specifies a 4.63V threshold versus the 4.65V of the original part. This 0.02V difference is within typical component tolerances and does not preclude functional equivalence for standard applications.

Frequently Asked Questions (FAQ)

Q: Can MAX813LCSA+ be used as a direct drop-in replacement for MAX813LCSA? A: Yes. MAX813LCSA+ maintains identical electrical specifications, package configuration, and pin assignment. It is the recommended direct substitute from the same manufacturer.

Q: What is the primary reason to substitute the MAX813LCSA? A: The MAX813LCSA is classified as obsolete. Substitute parts ensure long-term design support, procurement availability, and compliance with current regulatory standards.

Q: Are there differences in operating temperature ranges between substitute parts? A: Yes. The original MAX813LCSA operates from 0°C to 70°C. STM813LM6F and SP813LEN-L/TR both operate from -40°C to 85°C, providing extended thermal capability suitable for industrial applications.

Q: Does the 4.63V threshold of STM813LM6F affect compatibility with MAX813LCSA designs? A: The 0.02V difference between 4.63V and 4.65V is within standard component tolerance ranges and does not compromise functional equivalence for typical power management applications.

Q: Are all substitute parts RoHS compliant? A: Yes. All three substitute parts (MAX813LCSA+, STM813LM6F, and SP813LEN-L/TR) are RoHS3 compliant, whereas the original MAX813LCSA is RoHS non-compliant.

Q: What is the package compatibility across all parts? A: All parts use the 8-SOIC surface mount package with identical dimensions (0.154", 3.90mm width). PCB footprints and assembly processes are fully compatible.

Q: Which substitute part offers the best long-term availability? A: All three substitute parts carry active product status. Current inventory levels are: SP813LEN-L/TR (17,800 pcs), STM813LM6F (12,700 pcs), and MAX813LCSA+ (3,091 pcs).
