AP1702DWG-7 Equivalent & Substitute Parts

Part Overview

The AP1702DWG-7 is a single-channel power supply supervisor IC manufactured by Diodes Incorporated, designed for simple reset and power-on reset applications. This device features push-pull, totem pole output configuration and operates across a 0°C to 70°C temperature range in SC-59-3 surface mount packaging.

The AP1702DWG-7 is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain reliability, and support long-term product availability for applications currently utilizing this supervisor IC.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AP1702DWG-7 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Voltage threshold: 3.08V
• Output configuration: Push-Pull, Totem Pole
• Reset logic: Active High
• Number of voltages monitored: 1
• Mounting type: Surface Mount
• Package compatibility: TO-236-3, SC-59, SOT-23-3 family

Allowable Variations:

• Reset timeout: Substitute parts may exceed the 100ms minimum specification (140ms acceptable)
• Operating temperature range: Substitute parts may provide extended temperature coverage beyond 0°C ~ 70°C
• Moisture sensitivity level: Substitute parts may have lower MSL ratings (improved moisture resistance)
• Product status: Active parts are preferred over obsolete parts for long-term availability
• Packaging format: Tape & Reel (TR) or Cut Tape (CT) acceptable for equivalent functionality

Substitute parts are grouped into two categories: direct manufacturer equivalents from Diodes Incorporated and manufacturer-recommended alternatives from qualified suppliers (Analog Devices Inc., Microchip Technology).

Parameter Comparison

Engineering Selection Recommendations

For Direct Manufacturer Continuity: APX810-31SAG-7 is the primary substitute from Diodes Incorporated. This part maintains the same voltage threshold and output configuration while offering active product status, extended operating temperature range (-40°C ~ 85°C), and improved moisture resistance (MSL 1). The SOT-23-3 package is compatible within the TO-236-3 family. Reset timeout increases to 140ms minimum, which remains acceptable for most power-on reset applications.

For Extended Temperature Applications: ADM810TARTZ-REEL7 (Analog Devices Inc.) and TCM810TVNB713 (Microchip Technology) both support -40°C ~ 125°C operating range. Both are active products with ROHS3 compliance and MSL 1 rating. Selection between these depends on packaging preference (Tape & Reel versus Cut Tape) and supply chain availability.

For Standard Temperature Range Applications: TCM810TENB713 (Microchip Technology) provides -40°C ~ 85°C coverage with active product status, ROHS3 compliance, and MSL 1 rating in Cut Tape packaging.

All substitute parts maintain ROHS3 compliance and REACH unaffected status consistent with the original AP1702DWG-7.

Frequently Asked Questions (FAQ)

Q: Can AP1702DWG-7 be directly replaced with APX810-31SAG-7? A: Yes. Both parts share identical voltage threshold (3.08V), output configuration (push-pull, totem pole), and reset logic (active high). The APX810-31SAG-7 is functionally equivalent with improved specifications: active product status, extended temperature range, and lower moisture sensitivity. Package compatibility is maintained within the TO-236-3 family.

Q: What is the difference between SC-59-3 and SOT-23-3 packaging? A: SC-59-3 and SOT-23-3 are equivalent designations for the same three-pin surface mount package (TO-236-3 family). Substitute parts specified as SOT-23-3 are mechanically and electrically compatible with SC-59-3 footprints.

Q: Why do substitute parts have 140ms reset timeout instead of 100ms? A: The 140ms minimum reset timeout in active substitute parts exceeds the original 100ms specification. This longer timeout remains functionally acceptable for power-on reset applications and does not compromise circuit operation. The increased timeout provides additional margin for power supply stabilization.

Q: Is AP1704DWG-7 a suitable substitute? A: AP1704DWG-7 matches all critical electrical parameters (3.08V threshold, push-pull output, active high reset, 100ms timeout) and packaging (SC-59-3). However, it is also classified as obsolete. This part is suitable only if supply availability is confirmed and long-term sourcing is not a concern.

Q: Which substitute part offers the widest operating temperature range? A: Both ADM810TARTZ-REEL7 and TCM810TVNB713 support -40°C ~ 125°C operating range, providing the widest temperature coverage among available substitutes.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts maintain ROHS3 compliance and REACH unaffected status consistent with the original AP1702DWG-7.
