MAX816CSA Equivalent & Substitute Parts
Part Overview
The MAX816CSA is a supervisor integrated circuit designed for power management applications, specifically functioning as a simple reset/power-on reset controller with push-pull output capability. This component monitors a single voltage channel and provides active high/active low reset functionality with a 140ms minimum reset timeout.
The MAX816CSA is classified as an obsolete product. Identifying equivalent and substitute parts is necessary to maintain system continuity, support legacy designs, and ensure component availability for production and repair applications.

Substitute Part Grouping Explanation
Substitution of the MAX816CSA is determined by strict equivalence across the following critical parameters:
- Functional Type: Simple reset/power-on reset supervisor with single-channel voltage monitoring
- Output Configuration: Push-pull output topology
- Reset Logic Capability: Active high/active low selectable operation
- Reset Timeout: 140ms minimum specification
- Operating Temperature Range: 0°C to 70°C
- Package Form Factor: 8-SOIC surface mount package with 3.90mm width
- Voltage Threshold Control: Adjustable/selectable threshold capability
- Electrical Interface: Single voltage monitoring channel
The MAX816CSA+ qualifies as a direct substitute based on identical electrical specifications, functional characteristics, and package compatibility. The primary distinction between these parts is product status and compliance certification.

Engineering Selection Recommendations
The MAX816CSA+ is the direct substitute for the MAX816CSA. Both components share identical electrical specifications, functional characteristics, and package form factors, ensuring pin-for-pin compatibility and functional equivalence in circuit applications.
The MAX816CSA+ offers the advantage of active product status and ROHS3 compliance certification, making it the preferred selection for new designs and production applications subject to environmental regulations. The MAX816CSA remains available for legacy system support and repair applications where existing inventory exists.
For applications requiring RoHS compliance or long-term component availability assurance, the MAX816CSA+ is the appropriate selection. Both parts maintain identical operating temperature ranges, reset timeout specifications, and voltage monitoring capabilities.
Frequently Asked Questions (FAQ)
Q: Can the MAX816CSA+ be used as a direct replacement for the MAX816CSA in existing designs?
A: Yes. The MAX816CSA+ is a direct substitute with identical electrical specifications, functional operation, and 8-SOIC package compatibility. No circuit modifications are required for substitution.
Q: What is the primary difference between the MAX816CSA and MAX816CSA+?
A: The MAX816CSA+ is an active product with ROHS3 compliance certification, while the MAX816CSA is classified as obsolete and RoHS non-compliant. Electrical and functional specifications are identical.
Q: Are there any package or pinout differences between these parts?
A: No. Both components use the 8-SOIC surface mount package with 3.90mm width. Pinout and package dimensions are identical.
Q: What voltage monitoring capability does the MAX816CSA provide?
A: The MAX816CSA monitors a single voltage channel with adjustable/selectable threshold capability. Reset logic operates in active high or active low configuration.
Q: What is the reset timeout specification for the MAX816CSA?
A: The reset timeout is specified at 140ms minimum for both the MAX816CSA and MAX816CSA+.
Q: Is the MAX816CSA suitable for new product designs?
