AP1702BWL-7 Equivalent & Substitute Parts

Part Overview

The AP1702BWL-7 is a single-channel power supply supervisor IC manufactured by Diodes Incorporated, designed for push-pull, totem pole output applications in power management circuits. This device monitors a single voltage threshold at 4.38V and provides active-high reset signaling with a 100ms minimum timeout. The part is classified as obsolete, making equivalent and substitute parts necessary for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AP1702BWL-7 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Voltage threshold: 4.38V
• Output configuration: Push-Pull, Totem Pole
• Reset polarity: Active High
• Number of monitored voltages: 1
• Mounting type: Surface Mount
• Package compatibility: TO-236-3, SC-59, SOT-23-3

Allowable Variations:

• Reset timeout: Minimum 100ms or greater
• Operating temperature range: May extend beyond 0°C ~ 70°C
• Moisture sensitivity level: May be lower (MSL 1 acceptable)
• Product status: Active parts preferred over obsolete
• Packaging format: Tape & Reel (TR) or Cut Tape (CT) acceptable

Substitute parts are grouped into three categories: direct manufacturer equivalents from Diodes Incorporated, parametric equivalents from alternative manufacturers, and manufacturer-recommended alternatives.

Parameter Comparison

Engineering Selection Recommendations

Diodes Incorporated Direct Alternatives: APX810-44SAG-7 is the primary active-status substitute from the original manufacturer. It maintains the 4.38V threshold, push-pull totem pole output, and active-high reset configuration. The reset timeout increases to 140ms minimum, which is compatible with applications tolerating longer timeout periods. Operating temperature extends to -40°C ~ 85°C, and MSL rating improves to 1. This part is available in active production status with 3200 units in stock.

AP1702BWG-7 and AP1704BWG-7 are parametric equivalents within the Diodes Incorporated product line, maintaining identical electrical specifications to the AP1702BWL-7. Both remain obsolete, making them suitable only for direct replacement in existing inventory scenarios.

Cross-Manufacturer Alternatives: ADM810MARTZ-REEL7 (Analog Devices Inc.) and TCM810MENB713 / TCM810MVNB713 (Microchip Technology) are manufacturer-recommended substitutes meeting all critical electrical parameters. All three are active-status parts with improved MSL ratings and extended operating temperature ranges. TCM810MVNB713 offers the widest temperature range (-40°C ~ 125°C) and highest inventory availability (4200 units).

Compliance Status: All substitute parts maintain ROHS3 compliance, REACH unaffected status, and EAR99 export classification, matching the original part's regulatory profile.

Frequently Asked Questions (FAQ)

Q: Can APX810-44SAG-7 directly replace AP1702BWL-7 in existing designs? A: Yes. Both parts share the 4.38V threshold, push-pull totem pole output, and active-high reset polarity. The 140ms reset timeout of APX810-44SAG-7 is longer than the 100ms minimum of AP1702BWL-7, which is acceptable in most applications. Verify that your circuit design does not depend on the shorter timeout specification.

Q: What is the difference between SC-59-3 and SOT-23-3 packages? A: Both designations refer to the same three-pin surface mount package (TO-236-3). SC-59-3 and SOT-23-3 are equivalent package identifiers used by different manufacturers. Physical dimensions and pin configurations are identical, allowing direct PCB substitution.

Q: Why do some substitutes have MSL 1 instead of MSL 3? A: MSL 1 (Unlimited moisture sensitivity level) indicates superior moisture resistance compared to MSL 3 (168 hours). Parts with MSL 1 require less stringent moisture control during storage and handling, reducing production risk and cost.

Q: Are Microchip TCM810 parts suitable for high-temperature applications? A: TCM810MVNB713 operates to 125°C, making it suitable for extended temperature applications. TCM810MENB713 operates to 85°C. Both exceed the original AP1702BWL-7 specification of 70°C maximum.

Q: Which substitute offers the best inventory availability? A: TCM810MENB713 (Microchip Technology) has the highest stock level at 38,400 units, followed by AP1702BWG-7 (Diodes Incorporated) at 6,300 units.

Q: Can I use AP1702BWG-7 or AP1704BWG-7 as long-term solutions? A: These parts are classified as obsolete. While electrically equivalent to AP1702BWL-7, they are not recommended for new designs or long-term production due to discontinued status. Use active-status alternatives (APX810-44SAG-7, ADM810MARTZ-REEL7, or TCM810 series) for sustained supply chain reliability.
