DS1708EPA Equivalent & Substitute Parts

Part Overview

The DS1708EPA is a MicroMonitor™ supervisor integrated circuit manufactured by Analog Devices Inc./Maxim Integrated, designed for power management and reset signal generation in electronic systems. This device functions as a simple reset/power-on reset controller with push-pull output capability, monitoring a single voltage threshold at 4.4V. The DS1708EPA is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system support, maintenance, and new design implementations where legacy component replacement is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DS1708EPA is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Single voltage monitoring channel
• 4.4V voltage threshold
• Push-pull output configuration
• Active High/Active Low reset logic
• 8-DIP (0.300", 7.62mm) through-hole package
• Operating temperature range of -40°C to 85°C

Allowable Variation Parameters:

• Reset timeout: Minimum 130ms or greater
• Product status: Active or obsolete
• RoHS compliance: May differ based on manufacturing date
• Packaging format: Tube or alternative supplier packaging

The DS1708EPA+ and ADM708ANZ meet these substitution criteria. Both devices maintain identical voltage monitoring, threshold, output, and reset logic specifications while operating within compatible temperature ranges and package dimensions.

Parameter Comparison

Engineering Selection Recommendations

DS1708EPA+ (Parametric Equivalent): The DS1708EPA+ is a direct parametric equivalent with identical electrical specifications and package configuration. This part is currently in active production status with ROHS3 compliance, addressing regulatory requirements that the original DS1708EPA does not meet. The DS1708EPA+ maintains the 130ms minimum reset timeout and is suitable for applications requiring exact electrical performance matching. Availability is confirmed at 1093 pieces in new original stock.

ADM708ANZ (Manufacturer Recommended Alternative): The ADM708ANZ is the manufacturer-recommended substitute, also in active production with ROHS3 compliance. This device maintains all critical electrical parameters including the 4.4V threshold, push-pull output, and active high/active low reset logic. The ADM708ANZ specifies a 160ms minimum reset timeout, which exceeds the DS1708EPA requirement and remains compatible with system timing requirements. This part offers the highest inventory availability at 4626 pieces in new original stock.

Both substitute parts are suitable for direct replacement in applications where the DS1708EPA is no longer available. Selection between DS1708EPA+ and ADM708ANZ should be based on specific system timing requirements and supply chain considerations.

Frequently Asked Questions (FAQ)

Q: Can the DS1708EPA+ be used as a direct replacement for the DS1708EPA?

A: Yes. The DS1708EPA+ maintains identical electrical specifications including voltage threshold (4.4V), output configuration (push-pull), reset logic (active high/active low), and package dimensions (8-DIP). The primary difference is product status and RoHS compliance, with DS1708EPA+ being actively manufactured and ROHS3 compliant.

Q: What is the difference between the DS1708EPA+ and ADM708ANZ?

A: Both parts meet the core substitution criteria with matching voltage thresholds, output configurations, and package types. The ADM708ANZ specifies a 160ms minimum reset timeout compared to the DS1708EPA+ at 130ms. Both are active products with ROHS3 compliance. The ADM708ANZ is the manufacturer-recommended alternative.

Q: Are there any package compatibility concerns when substituting these parts?

A: No. All three parts use the 8-DIP (0.300", 7.62mm) through-hole package with 8-PDIP supplier device packaging. Pin-to-pin compatibility is maintained across all substitutes.

Q: Does the reset timeout difference between DS1708EPA+ (130ms) and ADM708ANZ (160ms) affect compatibility?

A: The ADM708ANZ's 160ms minimum timeout exceeds the DS1708EPA requirement of 130ms minimum. This longer timeout is compatible with systems designed for the original part, as it provides additional reset pulse duration. System-specific timing validation is necessary only if the application has maximum timeout constraints.

Q: What is the RoHS compliance status of these parts?

A: The DS1708EPA is RoHS non-compliant. Both substitute parts, DS1708EPA+ and ADM708ANZ, are ROHS3 compliant, meeting current regulatory requirements for electronic component manufacturing and distribution.

Q: Are all three parts available in the same packaging format?

A: The DS1708EPA is supplied in standard packaging. The DS1708EPA+ is supplied in tube packaging. The ADM708ANZ is supplied in tube packaging. All maintain the same 8-DIP physical form factor suitable for through-hole PCB assembly.
