ADM8693ANZ Equivalent & Substitute Parts

Part Overview

The ADM8693ANZ is a single-channel power supply supervisor IC manufactured by Analog Devices Inc., designed for battery backup circuit applications. This device monitors a 4.4V threshold voltage and provides push-pull output with active high/active low reset capability. The part is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing system support. The ADM8693ANZ operates across an industrial temperature range of -40°C to 85°C and is packaged in a 16-pin DIP configuration suitable for through-hole mounting applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the ADM8693ANZ is determined by strict alignment of the following critical parameters:

Primary Substitution Criteria:

• Single voltage monitoring channel
• 4.4V threshold voltage
• Push-pull output configuration
• Active high/active low reset capability
• 35ms minimum reset timeout
• 16-pin DIP package (0.300", 7.62mm)
• Through-hole mounting compatibility

Substitution Categories:

Direct Functional Equivalents (Full Parameter Match): Parts that match all critical electrical and mechanical parameters, including output type, reset timing, and operating temperature range. These parts are pin-compatible and functionally interchangeable without circuit modification.

Parametric Equivalents (Extended Temperature Range): Parts that match all critical parameters but offer extended operating temperature specifications, providing broader environmental compatibility while maintaining identical electrical performance.

Compatible Alternatives (Modified Output Type): Parts that match voltage monitoring, threshold, reset logic, and package specifications but employ open-drain/open-collector output instead of push-pull. These require circuit-level evaluation for compatibility.

Parameter Comparison

Engineering Selection Recommendations

MAX693EPE+ (Recommended Primary Substitute)

The MAX693EPE+ provides the closest functional match to the ADM8693ANZ. It maintains identical electrical specifications including push-pull output, 35ms reset timeout, and 4.4V threshold voltage. The operating temperature range of -40°C to 85°C matches the original part exactly, ensuring compatibility in industrial and extended-temperature applications. The part is currently in active production status with ROHS3 compliance and REACH unaffected certification, supporting long-term supply chain stability and regulatory compliance requirements.

MAX693CPE+ (Secondary Substitute)

The MAX693CPE+ offers identical electrical performance and package compatibility with the ADM8693ANZ. The primary distinction is the reduced operating temperature range of 0°C to 70°C, which limits applicability to commercial and industrial environments that do not require extended low-temperature operation. This part is actively produced with ROHS3 compliance and REACH unaffected status. Selection of this part requires confirmation that the application temperature requirements do not exceed the specified range.

LTC693CN#PBF (Conditional Substitute)

The LTC693CN#PBF shares the same package, voltage threshold, and reset logic configuration. However, two significant parameter differences require evaluation: the output type is open-drain/open-collector rather than push-pull, and the reset timeout is 140ms minimum instead of 35ms. These differences may require circuit-level modifications to maintain equivalent system behavior. The operating temperature range of 0°C to 70°C further restricts applicability. This part is suitable only when circuit design can accommodate open-drain output characteristics and extended reset timing.

Frequently Asked Questions (FAQ)

Q: Can MAX693EPE+ directly replace ADM8693ANZ without circuit modification?

A: Yes. The MAX693EPE+ maintains identical push-pull output configuration, 35ms reset timeout, 4.4V threshold voltage, and -40°C to 85°C operating temperature range. Pin-to-pin compatibility and electrical performance are equivalent, allowing direct substitution in existing designs.

Q: What is the key difference between MAX693CPE+ and MAX693EPE+?

A: Both parts are electrically identical with push-pull output and 35ms reset timeout. The difference is operating temperature range: MAX693CPE+ operates 0°C to 70°C, while MAX693EPE+ operates -40°C to 85°C. Selection depends on application temperature requirements.

Q: Why is LTC693CN#PBF listed as a substitute if it has different output and reset timing?

A: LTC693CN#PBF shares the same voltage monitoring channel, 4.4V threshold, active high/active low reset logic, and 16-DIP package. However, the open-drain output and 140ms reset timeout represent functional differences that may require circuit evaluation. This part is a compatible alternative only when circuit design can accommodate these parameter variations.

Q: Are all substitute parts RoHS compliant?

A: MAX693CPE+, MAX693EPE+, and LTC693CN#PBF are all ROHS3 compliant. The original ADM8693ANZ RoHS status is not specified in the provided data. All substitute parts are REACH unaffected.

Q: What is the moisture sensitivity level for these parts?

A: All parts listed, including ADM8693ANZ, MAX693CPE+, MAX693EPE+, and LTC693CN#PBF, have Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without moisture control requirements.

Q: Can these parts be used in surface-mount applications?

A: No. All parts in this comparison are through-hole mounted 16-DIP packages. Surface-mount alternatives would require a separate component search.
