MAX699CPA Equivalent & Substitute Parts

Part Overview

The MAX699CPA is a single-channel power supply supervisor IC manufactured by Analog Devices Inc./Maxim Integrated, designed for power-on reset and supervisory functions in electronic systems. This device operates as a simple reset controller with open drain or open collector output configuration. The MAX699CPA is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing system support. Active alternatives with identical or compatible electrical and mechanical specifications are available from the same manufacturer family.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MAX699CPA are classified based on strict electrical and mechanical compatibility criteria. The primary substitution parameters are:

• Voltage threshold: 4.65V
• Output type: Open Drain or Open Collector
• Reset logic: Active Low
• Reset timeout: 140ms Minimum
• Package: 8-DIP (0.300", 7.62mm)
• Mounting type: Through Hole
• Number of voltages monitored: 1 channel

Direct Manufacturer Equivalent: MAX699CPA+ maintains identical electrical specifications and packaging, with the primary difference being active product status and improved RoHS3 compliance.

Parametric Equivalents: MAX698CPA+ and LTC699CN8#PBF meet all core electrical parameters (voltage threshold, output type, reset logic, timeout, and package) and are functionally interchangeable in applications requiring these specifications.

Manufacturer Recommended Alternative: ADM699ANZ shares the same voltage threshold, reset timeout, package, and mounting type. The key difference is output configuration (Push-Pull instead of Open Drain/Open Collector) and extended operating temperature range (-40°C ~ 85°C), requiring circuit-level evaluation for compatibility.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement: MAX699CPA+ is the primary substitute, offering identical electrical specifications and packaging with active product status and ROHS3 compliance. This part is recommended for applications requiring no circuit modifications.

For Parametric Equivalence: MAX698CPA+ and LTC699CN8#PBF are functionally equivalent alternatives meeting all core electrical parameters. Both are active products with ROHS3 compliance and identical package specifications. Selection between these options may be based on availability and supply chain considerations.

For Extended Temperature Range Applications: ADM699ANZ extends the operating temperature range to -40°C ~ 85°C and provides dual reset logic capability (Active High/Active Low). However, the Push-Pull output configuration differs from the open drain/open collector topology of the original part. This substitute requires circuit-level evaluation to confirm compatibility with existing pull-up resistor networks and load characteristics.

All substitute parts maintain identical voltage threshold (4.65V), reset timeout (140ms minimum), package form factor (8-DIP), and mounting type (Through Hole), ensuring mechanical and thermal compatibility with existing PCB designs.

Frequently Asked Questions (FAQ)

Q: Can MAX699CPA+ be used as a direct replacement for MAX699CPA?

A: Yes. MAX699CPA+ maintains identical electrical specifications including 4.65V voltage threshold, open drain/open collector output, active low reset logic, and 140ms minimum reset timeout. The package (8-DIP) and mounting type (Through Hole) are identical. No circuit modifications are required.

Q: What is the difference between MAX698CPA+ and MAX699CPA+?

A: Both parts share identical electrical parameters (4.65V threshold, open drain/open collector output, active low reset, 140ms timeout) and package specifications. The primary difference is the base product number (MAX698 versus MAX699). Both are functionally interchangeable in applications requiring these specifications.

Q: Why is ADM699ANZ listed as a substitute if the output type is different?

A: ADM699ANZ is classified as a manufacturer-recommended alternative due to matching voltage threshold, reset timeout, package, and mounting specifications. However, the Push-Pull output configuration differs from the open drain/open collector topology. This substitute is suitable only for applications where the output stage can accommodate Push-Pull logic levels and does not rely on external pull-up resistors specific to open drain operation.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. MAX699CPA+ (Direct), MAX698CPA+ (Parametric), LTC699CN8#PBF (Parametric), and ADM699ANZ (Recommended) are all ROHS3 compliant. The original MAX699CPA is RoHS non-compliant, making these substitutes necessary for applications requiring RoHS compliance.

Q: Can these parts be used interchangeably in existing PCB designs?

A: MAX699CPA+, MAX698CPA+, and LTC699CN8#PBF are pin-compatible and electrically equivalent, requiring no PCB modifications. ADM699ANZ is pin-compatible but requires circuit evaluation due to output type differences. All parts use identical 8-DIP package (0.300", 7.62mm) and Through Hole mounting.

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

A: All parts, including the original MAX699CPA and all substitutes, have Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without moisture control requirements.
