AP1704AWG-7 Equivalent & Substitute Parts

Part Overview

The AP1704AWG-7 is a Power Management IC (PMIC) supervisor device manufactured by Diodes Incorporated, designed for single-channel voltage monitoring and reset signal generation. This component operates as a push-pull, totem pole output supervisor with active-high reset functionality, housed in a SC-59-3 (SOT-23-3) surface mount package.

The AP1704AWG-7 is classified as obsolete. Locating equivalent or substitute components is necessary for ongoing production support, design updates, or inventory replenishment when original stock becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AP1704AWG-7 are identified based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• Single-channel voltage monitoring capability
• Push-pull, totem pole output configuration
• Surface mount packaging in SC-59-3 / SOT-23-3 form factor
• Simple reset/power-on reset functionality
• ROHS3 compliance and EAR99 export classification

Substitution Categories:

Parametric Equivalent: AP1702AWG-7 matches all critical electrical and mechanical parameters of the AP1704AWG-7, including voltage threshold (4.63V), reset logic (active high), reset timeout (100ms minimum), operating temperature range (0°C ~ 70°C), and package type (SC-59-3). Both components are obsolete and share identical MSL ratings.

Direct Manufacturer Substitute: APX809-23SRG-7 is a Diodes Incorporated supervisor device with single-channel monitoring, push-pull totem pole output, and SC-59-3 / SOT-23-3 packaging. However, this part differs in voltage threshold (2.25V), reset logic (active low), reset timeout (140ms minimum), operating temperature range (-40°C ~ 85°C), and product status (not for new designs). These differences require circuit-level evaluation before substitution.

Parameter Comparison

Engineering Selection Recommendations

AP1702AWG-7 Selection: This part is the preferred parametric equivalent for direct replacement of the AP1704AWG-7. Both components share identical electrical specifications (4.63V threshold, active-high reset, 100ms timeout), matching operating temperature range (0°C ~ 70°C), and identical packaging (SC-59-3). Both are ROHS3 compliant and carry the same MSL rating. The obsolete status of both parts does not affect functional compatibility. This substitution requires no circuit modifications.

APX809-23SRG-7 Selection: This part is a functional supervisor from the same manufacturer but with significant parameter differences. The voltage threshold differs (2.25V versus 4.63V), reset logic is inverted (active low versus active high), reset timeout is longer (140ms versus 100ms), and operating temperature range is extended (-40°C ~ 85°C versus 0°C ~ 70°C). The product status is "not for new designs." Substitution of APX809-23SRG-7 requires circuit-level evaluation and potential firmware or logic adjustments to accommodate the active-low reset signal and different voltage threshold. This part is suitable only when design modifications are acceptable.

Compliance Considerations: All three parts maintain ROHS3 compliance and EAR99 export classification, ensuring regulatory consistency across substitution options.

Frequently Asked Questions (FAQ)

Q: Can AP1702AWG-7 be used as a direct replacement for AP1704AWG-7?

A: Yes. The AP1702AWG-7 is a parametric equivalent with identical voltage threshold (4.63V), reset logic (active high), reset timeout (100ms minimum), operating temperature range (0°C ~ 70°C), and package type (SC-59-3). No circuit modifications are required.

Q: What are the key differences between AP1704AWG-7 and APX809-23SRG-7?

A: The APX809-23SRG-7 differs in four critical parameters: voltage threshold (2.25V vs. 4.63V), reset logic (active low vs. active high), reset timeout (140ms vs. 100ms minimum), and operating temperature range (-40°C ~ 85°C vs. 0°C ~ 70°C). These differences require circuit evaluation before substitution.

Q: Why is the reset logic difference between AP1704AWG-7 and APX809-23SRG-7 significant?

A: Reset logic polarity (active high versus active low) determines the signal state that triggers a reset condition. Active-high resets when the output goes high; active-low resets when the output goes low. Inverting this logic without corresponding circuit or firmware changes will cause incorrect reset behavior.

Q: Are packaging formats interchangeable between these parts?

A: All three parts use the same physical package (SC-59-3 / SOT-23-3) and mounting type (surface mount), making them mechanically interchangeable on the PCB. However, packaging format differences (Tape & Reel versus Cut Tape & Digi-Reel) affect procurement and handling only, not electrical compatibility.

Q: What does "not for new designs" mean for APX809-23SRG-7?

A: This status indicates the part is available for existing production support but is not recommended for new product development. Diodes Incorporated may discontinue this part or limit availability. For new designs, AP1702AWG-7 or AP1704AWG-7 are preferred options.

Q: Do all three parts meet the same moisture sensitivity requirements?

A: No. AP1704AWG-7 and AP1702AWG-7 both have MSL 3 (168 hours), while APX809-23SRG-7 has MSL 1 (unlimited). MSL 1 provides superior moisture tolerance and requires less stringent storage and handling controls.

Q: Are there any export or compliance restrictions on these parts?

A: All three parts are classified as EAR99 and REACH unaffected, with ROHS3 compliance. No additional export or environmental restrictions apply beyond standard EAR99 regulations.
