AP1704GWG-7 Equivalent & Substitute Parts

Part Overview

The AP1704GWG-7 is a Power Management IC (PMIC) supervisor device manufactured by Diodes Incorporated. It functions as a simple reset/power-on reset controller with push-pull, totem pole output configuration, monitoring a single voltage threshold at 2.25V. The device is packaged in SC-59-3 (SOT-23-3) surface mount format.

The AP1704GWG-7 is classified as obsolete. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support ongoing production or maintenance requirements for systems utilizing this supervisor IC.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AP1704GWG-7 are identified based on the following critical parameters that determine functional compatibility:

Primary Substitution Criteria:

• Supervisor IC type: Simple Reset/Power-On Reset
• Number of voltages monitored: 1 channel
• Output configuration: Push-Pull, Totem Pole
• Reset logic: Active High
• Package compatibility: Surface mount, SC-59-3 / SOT-23-3 footprint
• Manufacturer: Diodes Incorporated

Voltage Threshold Tolerance: Substitute parts must operate within the same voltage monitoring range or provide equivalent threshold functionality.

Reset Timeout: Substitute parts must meet or exceed the 100ms minimum reset timeout specification.

Environmental Compliance: All substitute parts must maintain ROHS3 compliance and REACH unaffected status.

Two substitute parts are identified:

1. APX810-26SRG-7 - Direct manufacturer substitute with active product status and extended operating temperature range
2. AP1702GWG-7 - Parametric equivalent with identical voltage threshold and reset timeout specifications

Parameter Comparison

Engineering Selection Recommendations

APX810-26SRG-7 is the primary recommended substitute. This part carries active product status from Diodes Incorporated, ensuring long-term availability and supply chain stability. It maintains identical output configuration, reset logic, and package compatibility. The extended operating temperature range (-40°C ~ 85°C) provides broader environmental coverage compared to the original AP1704GWG-7. The improved moisture sensitivity level (MSL 1 vs. MSL 3) reduces handling and storage constraints. The voltage threshold difference (2.63V vs. 2.25V) and increased reset timeout (140ms vs. 100ms) must be evaluated against specific circuit requirements.

AP1702GWG-7 is a parametric equivalent with identical voltage threshold (2.25V) and reset timeout (100ms) specifications. However, this part shares obsolete product status with the original AP1704GWG-7, limiting its suitability for new designs or long-term production support.

Both substitute parts maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements equivalent to the original part.

Frequently Asked Questions (FAQ)

Q: Can APX810-26SRG-7 be used as a direct replacement for AP1704GWG-7?

A: APX810-26SRG-7 is functionally compatible as a supervisor IC with identical output configuration and reset logic. The voltage threshold differs (2.63V vs. 2.25V) and reset timeout is longer (140ms vs. 100ms). Circuit design must accommodate these parameter differences. Package and footprint compatibility are maintained.

Q: What is the significance of the voltage threshold difference between AP1704GWG-7 (2.25V) and APX810-26SRG-7 (2.63V)?

A: The voltage threshold determines the supply voltage level at which the supervisor IC triggers a reset signal. A higher threshold (2.63V) means the reset is triggered at a higher supply voltage compared to the original part (2.25V). Circuit design must verify that the higher threshold is acceptable for the intended application.

Q: Why is APX810-26SRG-7 recommended over AP1702GWG-7?

A: APX810-26SRG-7 carries active product status, ensuring ongoing manufacturer support and supply availability. AP1702GWG-7 is obsolete, presenting long-term supply chain risk. For new designs or sustained production, APX810-26SRG-7 is the preferred choice.

Q: Are all substitute parts available in the same package format?

A: Yes. All parts—AP1704GWG-7, APX810-26SRG-7, and AP1702GWG-7—are packaged in SC-59-3 (SOT-23-3) surface mount format with identical footprint compatibility.

Q: What is the impact of the MSL rating difference?

A: AP1704GWG-7 and AP1702GWG-7 have MSL 3 (168 hours), requiring controlled moisture exposure during storage and handling. APX810-26SRG-7 has MSL 1 (unlimited), eliminating moisture sensitivity constraints. This reduces handling complexity and storage requirements for APX810-26SRG-7.

Q: Do all substitute parts meet the same regulatory compliance standards?

A: Yes. All three parts are ROHS3 compliant and REACH unaffected, meeting equivalent regulatory requirements.
