MAX693CPE Equivalent & Substitute Parts

Part Overview

The MAX693CPE is a supervisor integrated circuit designed for power management applications, specifically functioning as a battery backup circuit with single-channel voltage monitoring. This part is classified as obsolete, which necessitates identification of equivalent and substitute components for ongoing design support and procurement continuity. The MAX693CPE operates within the 0°C to 70°C temperature range and provides push-pull output configuration with active high/active low reset functionality. Equivalent parts must maintain functional compatibility across critical electrical and mechanical parameters while accounting for product status and compliance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX693CPE is determined by strict alignment of the following critical parameters:

Mandatory Compatibility Parameters:

• Single-channel voltage monitoring capability
• 4.4V voltage threshold setting
• 16-DIP (0.300", 7.62mm) package format
• Through-hole mounting type
• Active high/active low reset functionality
• Moisture sensitivity level 1 (Unlimited)

Acceptable Variation Parameters:

• Output configuration (push-pull or open drain/open collector acceptable with circuit design verification)
• Reset timeout duration (minimum 35ms required; longer timeouts acceptable)
• Operating temperature range (extended ranges acceptable; minimum 0°C to 70°C coverage required)
• Product status (active status preferred for procurement; obsolete status acceptable for legacy applications)
• RoHS compliance status (both compliant and non-compliant acceptable depending on application requirements)

The substitute parts identified—MAX693CPE+, ADM693ANZ, and LTC693CN#PBF—maintain the core functional parameters while offering variations in output stage configuration and operating temperature specifications.

Parameter Comparison

Engineering Selection Recommendations

MAX693CPE+ (Direct Equivalent) The MAX693CPE+ is the primary substitute for the obsolete MAX693CPE. This part maintains identical electrical specifications, package format, and output configuration. The MAX693CPE+ carries active product status and ROHS3 compliance, providing improved procurement availability and regulatory alignment compared to the original part. Selection of MAX693CPE+ is appropriate for direct replacement in existing designs without circuit modification.

ADM693ANZ (Extended Temperature Alternative) The ADM693ANZ functions as a substitute with extended operating temperature range (-40°C to 85°C) and active product status. This part differs in output configuration, providing open drain and push-pull outputs rather than dual push-pull. The ADM693ANZ is suitable for applications requiring expanded temperature performance or when open drain output compatibility exists in the circuit design. ROHS3 compliance supports modern procurement requirements.

LTC693CN#PBF (Extended Reset Timeout Alternative) The LTC693CN#PBF provides substitution capability with extended reset timeout specification (140ms minimum versus 35ms minimum). This part features open drain or open collector output configuration and active product status with ROHS3 compliance. Selection of LTC693CN#PBF is appropriate when circuit design accommodates extended reset timing and open drain/open collector output stages. Operating temperature range matches the original specification (0°C to 70°C).

Frequently Asked Questions (FAQ)

Q: Can MAX693CPE+ be used as a direct replacement for MAX693CPE? A: Yes. The MAX693CPE+ maintains identical electrical specifications, voltage threshold (4.4V), reset timeout (35ms minimum), output configuration (push-pull), and package format (16-DIP). The primary difference is product status (active versus obsolete) and RoHS compliance (ROHS3 compliant versus non-compliant). Direct substitution is supported without circuit modification.

Q: What is the key difference between ADM693ANZ and MAX693CPE? A: The ADM693ANZ provides extended operating temperature range (-40°C to 85°C versus 0°C to 70°C) and differs in output configuration (open drain and push-pull versus dual push-pull). All other critical parameters including voltage threshold, reset timeout, and package format remain compatible. Circuit design must accommodate the open drain output stage.

Q: Why does LTC693CN#PBF have a longer reset timeout specification? A: The LTC693CN#PBF is specified with 140ms minimum reset timeout compared to 35ms minimum for MAX693CPE. This difference reflects the internal design of the LTC693 supervisor architecture. Circuit designs must verify that extended reset timing is acceptable for the application. Output configuration (open drain or open collector) also differs from the original part.

Q: Are all substitute parts available in the same package format? A: Yes. All substitute parts—MAX693CPE+, ADM693ANZ, and LTC693CN#PBF—are packaged in 16-DIP (0.300", 7.62mm) format with through-hole mounting. Direct PCB compatibility is maintained across all substitutes.

Q: Which substitute part offers the best compliance profile? A: All three substitute parts carry ROHS3 compliance and REACH unaffected status. The original MAX693CPE is RoHS non-compliant. For applications requiring modern regulatory compliance, any of the three substitutes (MAX693CPE+, ADM693ANZ, or LTC693CN#PBF) provide equivalent compliance support.

Q: Can ADM693ANZ and LTC693CN#PBF be used interchangeably with MAX693CPE? A: Interchangeability requires circuit design verification. Both parts maintain the 4.4V voltage threshold and 16-DIP package format. However, ADM693ANZ provides open drain output (versus push-pull) and extended temperature range. LTC693CN#PBF provides open drain/open collector output and extended reset timeout (140ms). Circuit designs must accommodate these output stage and timing differences.
