DS1707EPA Equivalent & Substitute Parts

Part Overview

The DS1707EPA is a single-channel power supply supervisor IC manufactured by Analog Devices Inc./Maxim Integrated, designed for power-on reset and simple reset applications. This component operates as a push-pull output supervisor with a 4.65V threshold and 130ms minimum reset timeout. The DS1707EPA is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing production requirements. Substitute parts must maintain identical electrical characteristics and mechanical compatibility while preferring active product status and current compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DS1707EPA is determined by strict equivalence across the following critical parameters:

• Single-channel voltage monitoring configuration
• 4.65V threshold voltage
• Push-pull output topology
• Active high/active low reset logic capability
• Operating temperature range of -40°C to 85°C
• 8-DIP through-hole package format (0.300", 7.62mm)
• 8-PDIP supplier device package designation

Parts meeting these criteria are classified as direct substitutes. Secondary consideration is given to reset timeout specifications, where variations indicate minor functional differences but do not preclude substitution if all primary parameters align. Product status and compliance certifications are secondary factors that influence selection priority but do not determine substitution eligibility.

Parameter Comparison

Engineering Selection Recommendations

DS1707EPA+ is the direct manufacturer equivalent, sharing identical electrical specifications and packaging with the obsolete DS1707EPA. This part is currently in active production status and complies with ROHS3 standards, making it the preferred choice for new designs and production continuity.

ADM707ANZ is a manufacturer-recommended alternative from Analog Devices Inc. It maintains electrical and mechanical compatibility across all critical parameters. The reset timeout specification of 160ms (versus 130ms for DS1707EPA) represents a minor functional difference that does not affect substitution eligibility. ADM707ANZ is active in production and ROHS3 compliant, providing an additional qualified option where supply or procurement considerations apply.

Both substitute parts are suitable for direct replacement in applications currently using the DS1707EPA, provided circuit design accommodates the specified reset timeout parameters.

Frequently Asked Questions (FAQ)

Q: Can DS1707EPA+ be used as a direct replacement for DS1707EPA?

A: Yes. DS1707EPA+ is the direct manufacturer equivalent with identical voltage threshold (4.65V), reset timeout (130ms minimum), output configuration (push-pull), and 8-DIP package specifications. The primary difference is product status (active versus obsolete) and ROHS3 compliance.

Q: What is the functional difference between DS1707EPA and ADM707ANZ?

A: Both parts operate as single-channel power supply supervisors with identical 4.65V thresholds, push-pull outputs, and active high/active low reset logic. The ADM707ANZ specifies a 160ms minimum reset timeout compared to 130ms for DS1707EPA. This difference reflects timing tolerance variations but does not affect core substitution compatibility.

Q: Are all three parts mechanically interchangeable?

A: Yes. All three parts use the 8-DIP (0.300", 7.62mm) through-hole package format with 8-PDIP supplier designation, ensuring identical PCB footprint and mounting compatibility.

Q: What compliance certifications apply to substitute parts?

A: DS1707EPA+ and ADM707ANZ both comply with ROHS3 standards and are REACH unaffected. The original DS1707EPA is RoHS non-compliant. For applications requiring RoHS compliance, DS1707EPA+ or ADM707ANZ must be selected.

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

A: DS1707EPA+ is recommended for new designs as the direct manufacturer equivalent with active production status. ADM707ANZ is a qualified alternative where supply considerations or design flexibility regarding reset timeout specifications apply.
