DS1706LEPA Equivalent & Substitute Parts

Part Overview

The DS1706LEPA is a supervisor integrated circuit from Analog Devices Inc./Maxim Integrated's MicroMonitor™ series, designed for power management applications. This 1-channel power-on reset supervisor operates as a simple reset controller with push-pull totem pole output configuration. The device monitors a single voltage threshold at 4.65V and provides active-high reset signaling with a 130ms minimum timeout period.

The DS1706LEPA is classified as obsolete, which necessitates identification of equivalent substitute components for ongoing system support and new design implementations. Active equivalent parts ensure continued availability and compliance with current manufacturing standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DS1706LEPA is determined by strict equivalence across the following critical parameters:

• Voltage Monitoring: Single channel at 4.65V threshold
• Output Type: Push-pull totem pole configuration
• Reset Polarity: Active high reset signal
• Reset Timing: 130ms minimum timeout
• Temperature Range: -40°C to 85°C operation
• Package: 8-DIP through-hole form factor
• Electrical Characteristics: Identical functional specifications

The DS1706LEPA+ qualifies as a direct substitute based on complete parameter alignment across all monitored voltages, output characteristics, reset behavior, and package specifications. The primary distinction is product status and compliance certification.

Engineering Selection Recommendations

The DS1706LEPA+ is the direct functional equivalent for applications currently using the DS1706LEPA. Selection between these parts should be based on the following criteria:

For New Designs and Ongoing Production: The DS1706LEPA+ is the appropriate choice. This part maintains active product status with current manufacturing support and carries ROHS3 compliance certification, aligning with modern environmental and regulatory requirements.

For Legacy System Maintenance: The DS1706LEPA remains electrically and mechanically identical to the DS1706LEPA+. Existing inventory of the obsolete variant may be utilized where supply constraints exist, provided that RoHS non-compliance does not conflict with system-level requirements or regional regulations.

Compliance Considerations: The DS1706LEPA+ provides ROHS3 compliance, whereas the DS1706LEPA does not. Both parts maintain REACH unaffected status. Systems subject to RoHS directives should transition to the DS1706LEPA+.

Frequently Asked Questions (FAQ)

Q: Can the DS1706LEPA+ be used as a direct replacement for the DS1706LEPA in existing designs?

A: Yes. The DS1706LEPA+ is electrically and mechanically identical to the DS1706LEPA across all functional parameters, including voltage threshold, output configuration, reset timing, temperature range, and 8-DIP package specifications. Pin-for-pin compatibility is maintained.

Q: What is the primary difference between DS1706LEPA and DS1706LEPA+?

A: The DS1706LEPA+ is the active production variant with ROHS3 compliance certification. The DS1706LEPA is classified as obsolete and does not carry RoHS3 compliance. Electrical and mechanical specifications are identical.

Q: Are there any package or mounting differences between these parts?

A: No. Both parts use the 8-DIP (0.300", 7.62mm) through-hole package with identical pin configurations and mounting requirements.

Q: Which part should be specified for new designs?

A: The DS1706LEPA+ should be specified for new designs. This part carries active product status and current compliance certifications, ensuring long-term availability and regulatory alignment.

Q: Is the DS1706LEPA still available for purchase?

A: The DS1706LEPA is classified as obsolete. While legacy inventory may exist, the DS1706LEPA+ is the recommended source for ongoing procurement.

Q: Do these parts have identical reset timeout specifications?

A: Yes. Both the DS1706LEPA and DS1706LEPA+ provide a 130ms minimum reset timeout with active-high reset logic and identical voltage threshold monitoring at 4.65V.
