MAX709RCSA Equivalent & Substitute Parts

Part Overview

The MAX709RCSA 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. The device is currently listed as obsolete, which necessitates identification of equivalent and substitute components for ongoing design support and production requirements. Active alternatives with identical or equivalent electrical and mechanical specifications are available to ensure design continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the MAX709RCSA is determined by strict equivalence across the following critical parameters:

• Voltage Monitoring Capability: Single channel, 2.63V threshold
• Output Type: Push-Pull, Totem Pole configuration
• Reset Behavior: Active Low logic with 140ms minimum timeout
• Package Compatibility: 8-SOIC surface mount form factor
• Thermal Range: 0°C to 70°C operating temperature
• Functional Classification: Simple Reset/Power-On Reset supervisor

Two substitute parts meet these criteria: MAX709RCSA+ (direct manufacturer variant) and MAX706RCSA+ (parametric equivalent from the same manufacturer family). Both maintain identical electrical specifications and mechanical compatibility with the original MAX709RCSA.

Parameter Comparison

Engineering Selection Recommendations

For new designs and production continuity, MAX709RCSA+ is the primary substitute, offering direct compatibility with identical electrical and mechanical specifications while maintaining active product status and ROHS3 compliance. MAX706RCSA+ serves as a parametric equivalent alternative, providing the same functional performance and package compatibility with equivalent compliance certifications.

The original MAX709RCSA, classified as obsolete, should be replaced in active production environments. Both substitute parts are available in active inventory and meet current regulatory requirements, including ROHS3 compliance and REACH unaffected status.

Frequently Asked Questions (FAQ)

Q: Can MAX709RCSA+ be used as a direct replacement for MAX709RCSA?

A: Yes. MAX709RCSA+ maintains identical electrical specifications, including 2.63V threshold voltage, 140ms reset timeout, active low reset logic, and push-pull totem pole output. The 8-SOIC package and surface mount configuration are unchanged. The primary difference is product status (active versus obsolete) and RoHS compliance (ROHS3 compliant versus non-compliant).

Q: What is the difference between MAX709RCSA+ and MAX706RCSA+?

A: Both parts are parametric equivalents with identical voltage threshold, output configuration, reset behavior, and package specifications. The base product numbers differ (MAX709 versus MAX706), but electrical and mechanical compatibility is maintained. Both are active products with ROHS3 compliance.

Q: Are there any package or pinout differences between these parts?

A: No. All three parts use the 8-SOIC package with 0.154" width (3.90mm). Surface mount configuration and pinout compatibility are maintained across MAX709RCSA, MAX709RCSA+, and MAX706RCSA+.

Q: What is the inventory status of substitute parts?

A: MAX709RCSA+ has 1760 pieces in stock. MAX706RCSA+ has 2710 pieces in stock. Both are available as new original components.

Q: Are there compliance or certification differences?

A: The original MAX709RCSA is RoHS non-compliant. Both substitute parts (MAX709RCSA+ and MAX706RCSA+) are ROHS3 compliant. All three parts maintain REACH unaffected status and EAR99 ECCN classification.
