AP1702CWG-7 Equivalent & Substitute Parts

Part Overview

The AP1702CWG-7 is a supervisor integrated circuit manufactured by Diodes Incorporated, designed for power management applications requiring single-channel voltage monitoring and reset signal generation. This device operates as a push-pull, totem pole output supervisor with active high reset functionality in a SC-59-3 surface mount package.

The AP1702CWG-7 is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for systems utilizing this supervisor topology.

Substitute Part Grouping Explanation

Substitution of the AP1702CWG-7 is determined by the following critical parameters that must remain consistent across equivalent parts:

Single-channel voltage monitoring capability
4V voltage threshold setting
Push-pull, totem pole output configuration
Active high reset logic
Surface mount technology with compatible package footprint (TO-236-3 / SC-59 / SOT-23-3)
ROHS3 compliance and REACH unaffected status

Substitute parts are grouped into three categories based on their relationship to the main part:

Direct Manufacturer Substitute: Parts from the same manufacturer (Diodes Incorporated) with identical electrical specifications but different package designations or product status.

Parametric Equivalents: Parts with matching electrical and functional parameters from the same manufacturer, maintaining identical threshold voltage, output topology, and reset characteristics.

Manufacturer Recommended Alternatives: Active production parts from alternative manufacturers (Analog Devices Inc., Microchip Technology) that meet or exceed the electrical specifications of the obsolete AP1702CWG-7.

Engineering Selection Recommendations

For Active Production Designs:

ADM810JARTZ-REEL7 (Analog Devices Inc.) and TCM810JVNB713 (Microchip Technology) are recommended as primary substitutes. Both parts are in active production status, offer extended operating temperature ranges (-40°C to 125°C), and provide improved moisture sensitivity ratings (MSL 1, Unlimited). These characteristics ensure long-term supply chain stability and enhanced reliability for new designs.

For Legacy System Support:

AP1704CWG-7 (Diodes Incorporated) serves as a parametric equivalent with identical electrical specifications and matching operating temperature range to the AP1702CWG-7. This part maintains the same SC-59-3 package designation and is suitable for direct replacement in existing assemblies where supply of the original part is unavailable.

For Intermediate Applications:

TCM810JENB713 (Microchip Technology) provides active production status with a -40°C to 85°C operating range, balancing supply availability with thermal performance suitable for standard industrial applications.

Package Consideration:

APX810-40SAG-7 (Diodes Incorporated) is classified as "Not For New Designs" but remains available. This part transitions from SC-59-3 to SOT-23-3 package designation. Physical footprint compatibility must be confirmed before selection, as package transition may require PCB layout modifications.

Frequently Asked Questions (FAQ)

Q: Can AP1702CWG-7 be directly replaced with APX810-40SAG-7?

A: Both parts share identical electrical specifications (4V threshold, push-pull totem pole output, active high reset). However, APX810-40SAG-7 uses SOT-23-3 package designation while AP1702CWG-7 uses SC-59-3. Physical footprint compatibility must be confirmed. APX810-40SAG-7 is also classified as "Not For New Designs," limiting its suitability for ongoing production.

Q: What is the difference between the reset timeout specifications?

A: AP1702CWG-7 specifies 100ms minimum reset timeout, while most substitute parts (APX810-40SAG-7, ADM810JARTZ-REEL7, TCM810JENB713, TCM810JVNB713) specify 140ms minimum. The longer timeout in substitute parts does not prevent functional compatibility but may affect system reset timing characteristics. Circuit-level timing analysis is required if reset timeout is critical to system operation.

Q: Which substitute part offers the widest operating temperature range?

A: ADM810JARTZ-REEL7 and TCM810JVNB713 both support -40°C to 125°C operating temperature range, compared to the original AP1702CWG-7 range of 0°C to 70°C. This extended range provides greater thermal margin for industrial and automotive applications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the regulatory compliance profile of the original AP1702CWG-7.

Q: What does MSL rating difference mean for component handling?

A: AP1702CWG-7 carries MSL 3 (168 Hours), requiring moisture bake-out procedures before reflow soldering if storage exceeds 168 hours in standard humidity conditions. Substitute parts with MSL 1 (Unlimited) have no moisture sensitivity restrictions and can be stored indefinitely under standard conditions, reducing manufacturing process complexity.

Q: Is AP1704CWG-7 a suitable replacement for AP1702CWG-7?

A: Yes. AP1704CWG-7 is a parametric equivalent with identical electrical specifications, threshold voltage, output topology, reset logic, and operating temperature range. Both parts use SC-59-3 package designation, enabling direct physical replacement. AP1704CWG-7 is also obsolete, so it is suitable only for legacy system support where supply is available.
