Mounting Type: Surface mount configuration
Number of Channels: Single-channel voltage monitoring
Reset Timeout: 140ms minimum (primary specification)
Output Configuration: Push-pull, totem pole topology
Moisture Sensitivity Level: MSL 1 (Unlimited)

Substitutes are grouped into two categories based on output reset logic compatibility:

Category A - Active High Reset (Direct Functional Equivalents):

MAX706PCSA+ (Analog Devices Inc./Maxim Integrated)
STM706PM6F (STMicroelectronics)
ADM706PARZ (Analog Devices Inc.)

Category B - Active Low Reset (Functional Variant):

Engineering Selection Recommendations

For Direct Functional Replacement (Active High Reset Logic):

MAX706PCSA+ is the primary equivalent, offering identical electrical specifications with active product status and ROHS3 compliance. This part maintains the original operating temperature range of 0°C ~ 70°C and is available in tube packaging.

STM706PM6F provides an alternative from STMicroelectronics with extended operating temperature range (-40°C ~ 85°C) and active product status. This part is available in tape & reel packaging, suitable for high-volume production environments.

ADM706PARZ from Analog Devices Inc. offers active product status and ROHS3 compliance with extended operating temperature range (-40°C ~ 85°C). Reset timeout specification is 160ms minimum, which exceeds the original 140ms minimum requirement. This part is available in tube packaging.

For Applications Requiring Active Low Reset Logic:

MIC706PMY and MIC706PMY-TR from Microchip Technology provide supervisor functionality with Active Low reset logic. These parts feature extended operating temperature range (-40°C ~ 85°C) and ROHS3 compliance. MIC706PMY is available in tube packaging; MIC706PMY-TR is available in tape & reel packaging. Output configuration is not specified in available documentation.

Compliance Considerations:

All substitute parts are ROHS3 compliant, addressing the non-compliance status of the original MAX706PCSA. All parts maintain REACH unaffected status and EAR99 ECCN classification.

Frequently Asked Questions (FAQ)

Q: Can MAX706PCSA+ be used as a direct replacement for MAX706PCSA?

A: Yes. MAX706PCSA+ maintains identical electrical specifications including 2.63V threshold, 140ms minimum reset timeout, active high reset logic, and push-pull totem pole output. Both parts use 8-SOIC packaging. The primary difference is product status (active vs. obsolete) and RoHS compliance (ROHS3 vs. non-compliant).

Q: What is the difference between Active High and Active Low reset logic?

A: Reset logic determines the signal state that triggers a reset condition. Active High reset occurs when the reset output transitions to a high logic level; Active Low reset occurs when the reset output transitions to a low logic level. Circuit design must accommodate the appropriate logic level for proper system operation.

Q: Are MIC706PMY and MIC706PMY-TR interchangeable?

A: Both parts are functionally identical with matching electrical specifications. The difference is packaging format: MIC706PMY is supplied in tube packaging for lower-volume applications; MIC706PMY-TR is supplied in tape & reel packaging for automated assembly and higher-volume production.

Q: Does STM706PM6F operate at the same temperature range as MAX706PCSA?

A: No. MAX706PCSA operates from 0°C ~ 70°C; STM706PM6F operates from -40°C ~ 85°C. STM706PM6F provides extended temperature range capability, suitable for applications requiring broader operating conditions.

Q: What is the significance of the 160ms reset timeout in ADM706PARZ compared to 140ms in MAX706PCSA?

A: Reset timeout specifies the minimum duration the reset output remains active after a power supply disturbance. ADM706PARZ's 160ms timeout exceeds the original 140ms specification, providing additional reset pulse duration. This difference must be evaluated against system reset requirements.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts listed are ROHS3 compliant. The original MAX706PCSA is RoHS non-compliant. Compliance status is relevant for applications subject to RoHS regulations.

Q: Can I use STM706PM6F in a design originally specified for MAX706PCSA?

A: Electrical substitution is valid based on matching threshold voltage, reset timeout, output configuration, and package type. The extended operating temperature range (-40°C ~ 85°C vs. 0°C ~ 70°C) provides additional capability. Tape & reel packaging is suitable for production environments. Verify system requirements accommodate the extended temperature range.
