MAX705CPA Equivalent & Substitute Parts

Part Overview

The MAX705CPA is a power management integrated circuit (PMIC) functioning as a supervisor with push-pull, totem pole output configuration. It monitors a single voltage channel and provides active-low reset functionality with a 140ms minimum reset timeout. The device is packaged in an 8-DIP through-hole format and operates across the 0°C to 70°C temperature range.

The MAX705CPA is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this supervisor IC.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX705CPA is determined by the following critical parameters:

• Voltage Threshold: 4.65V (must match exactly)
• Output Configuration: Push-Pull, Totem Pole (must match exactly)
• Reset Logic: Active Low (must match exactly)
• Number of Voltages Monitored: 1 (must match exactly)
• Package / Case: 8-DIP (0.300", 7.62mm) (must match exactly)
• Mounting Type: Through Hole (must match exactly)
• Supplier Device Package: 8-PDIP (must match exactly)

The substitute parts identified below meet all critical electrical and mechanical parameters. Variations in operating temperature range, reset timeout specifications, product status, and compliance certifications are noted but do not preclude functional substitution within their respective operating conditions.

Engineering Selection Recommendations

MAX705CPA+ (Direct Manufacturer Equivalent)

The MAX705CPA+ is the direct successor to the MAX705CPA, maintaining identical electrical specifications and package configuration. It is classified as active product status and complies with ROHS3 standards, addressing regulatory compliance requirements. This part is the primary choice for new designs or production transitions requiring RoHS compliance.

MAX709LCPA+ (Parametric Equivalent)

The MAX709LCPA+ meets all critical electrical and mechanical substitution criteria. It operates within the same 0°C to 70°C temperature range and maintains the 140ms minimum reset timeout. The part is active and ROHS3 compliant. The base product number differs (MAX709 versus MAX705), reflecting a variant within the supervisor IC family that maintains functional compatibility.

ADM705ANZ (Manufacturer Recommended Alternative)

The ADM705ANZ is an Analog Devices supervisor IC meeting all core electrical parameters. It extends the operating temperature range to -40°C ~ 85°C and specifies a 160ms minimum reset timeout. This part is active and ROHS3 compliant. The extended temperature range and slightly longer reset timeout must be evaluated against application requirements. The ADM705 base product number indicates a distinct product line within the Analog Devices supervisor portfolio.

Frequently Asked Questions (FAQ)

Q: Can MAX705CPA+ be used as a direct replacement for MAX705CPA?

A: Yes. The MAX705CPA+ maintains identical voltage threshold (4.65V), output configuration (push-pull, totem pole), reset logic (active low), and package specifications (8-DIP through-hole). The primary difference is product status (active versus obsolete) and RoHS compliance (ROHS3 compliant versus non-compliant).

Q: What is the difference between MAX709LCPA+ and MAX705CPA+?

A: Both parts meet identical electrical specifications and operate within the same temperature range (0°C ~ 70°C). The base product number differs (MAX709 versus MAX705), indicating distinct product variants. Both are functionally equivalent for applications requiring the specified 4.65V threshold and 140ms reset timeout.

Q: Can ADM705ANZ be used in place of MAX705CPA?

A: ADM705ANZ meets all critical electrical parameters (4.65V threshold, push-pull output, active-low reset, single voltage monitoring). The operating temperature range extends to -40°C ~ 85°C, and the reset timeout is specified as 160ms minimum. Applications operating within the original 0°C ~ 70°C range will function correctly. The extended temperature capability and longer reset timeout must be verified against circuit requirements.

Q: Are all substitute parts available in the same package?

A: Yes. All substitute parts are packaged in 8-DIP (0.300", 7.62mm) through-hole format with 8-PDIP supplier device package designation. Direct PCB substitution is supported without package modification.

Q: Which substitute part should be selected for new designs?

A: MAX705CPA+ is recommended for new designs, as it is the direct manufacturer equivalent with active product status and ROHS3 compliance. MAX709LCPA+ and ADM705ANZ are valid alternatives if inventory or application-specific temperature requirements necessitate their selection.

Q: What compliance certifications apply to these parts?

A: MAX705CPA+ and MAX709LCPA+ are ROHS3 compliant. ADM705ANZ is ROHS3 compliant. All parts are REACH unaffected and classified under ECCN EAR99. The original MAX705CPA is RoHS non-compliant.
