AP1701EWL-7 Equivalent & Substitute Parts

Part Overview

The AP1701EWL-7 is a supervisor integrated circuit in the Power Management (PMIC) category, manufactured by Diodes Incorporated. This device functions as a simple reset/power-on reset supervisor with push-pull, totem pole output configuration, monitoring a single voltage threshold at 2.93V. The part is packaged in SC-59-3 (SOT-23-3) surface mount format with a 100ms minimum reset timeout and active low reset output.

The AP1701EWL-7 carries an Obsolete product status. Equivalent and substitute parts are necessary for new designs, production continuity, and applications requiring extended operating temperature ranges or improved availability.

Substitute Part Grouping Explanation

Substitution of the AP1701EWL-7 is determined by the following critical parameters:

Voltage Threshold: 2.93V (all substitutes must match this specification)
Output Configuration: Push-Pull, Totem Pole (functional equivalence requirement)
Reset Logic: Active Low (functional equivalence requirement)
Package / Case: TO-236-3, SC-59, SOT-23-3 (mechanical and electrical compatibility)
Mounting Type: Surface Mount (assembly compatibility)
RoHS Status: ROHS3 Compliant (regulatory compliance)

Substitute parts are grouped into three categories:

Parametric Equivalents (Diodes Incorporated): Parts from the same manufacturer with identical core electrical specifications and the same package type, offering direct replacement capability.
Direct Manufacturer Alternatives (Diodes Incorporated): Parts with matching electrical parameters but different packaging options or product status classifications.
Cross-Manufacturer Equivalents (Analog Devices Inc., onsemi): Parts from alternative manufacturers meeting all critical electrical and mechanical parameters, suitable for applications requiring extended temperature ranges or improved long-term availability.

Engineering Selection Recommendations

For Direct Replacement (Same Operating Temperature Range):

AP1701EWG-7 is the primary equivalent for the AP1701EWL-7. Both parts share identical electrical specifications (2.93V threshold, 100ms reset timeout, 0°C ~ 70°C operating range) and SC-59-3 packaging. AP1701EWG-7 carries Active product status and MSL-1 rating, providing improved long-term availability and lower moisture sensitivity compared to the Obsolete AP1701EWL-7.

For Extended Temperature Range Applications:

ADM6326-29ARTZ-R7 and ADM809SARTZ-REEL7 (Analog Devices Inc.) and MAX809SEUR+T (Analog Devices Inc./Maxim Integrated) support operating temperatures from -40°C to 85°C or higher, exceeding the original 0°C ~ 70°C specification. These parts maintain the 2.93V threshold and push-pull totem pole output. All three carry Active product status and MSL-1 ratings. ADM6326-29ARTZ-R7 matches the 100ms reset timeout; ADM809SARTZ-REEL7 and MAX809SEUR+T specify 140ms minimum reset timeout.

For New Design Implementations:

Active product status parts are preferred: AP1701EWG-7 (Diodes Incorporated), ADM6326-29ARTZ-R7, ADM809SARTZ-REEL7, MAX809SEUR+, MAX809SEUR+T, and MAX809SEUR+T10. All are ROHS3 compliant and carry MSL-1 ratings.

Packaging Considerations:

The original AP1701EWL-7 uses SC-59-3 packaging. Substitutes using SOT-23-3 packaging (APX809-29SAG-7, ADM6326-29ARTZ-R7, ADM809SARTZ-REEL7, MAX809 series) are mechanically and electrically compatible within the TO-236-3 / SC-59 / SOT-23-3 family but require PCB layout verification for pin-to-pin compatibility.

Frequently Asked Questions (FAQ)

Q: Can AP1701EWG-7 be used as a direct replacement for AP1701EWL-7?

A: Yes. Both parts share identical electrical specifications (2.93V threshold, 100ms reset timeout, active low reset, push-pull totem pole output) and SC-59-3 packaging. AP1701EWG-7 is Active status with improved MSL-1 rating, making it the recommended equivalent.

Q: What is the difference between SC-59-3 and SOT-23-3 packaging?

A: SC-59-3 and SOT-23-3 are designations within the TO-236-3 package family and are mechanically and electrically compatible. Pin assignments and footprints are identical. Substitution between these designations does not require circuit redesign.

Q: Why do some substitutes specify 140ms reset timeout instead of 100ms?

A: Reset timeout is a specified parameter that affects the duration of the reset pulse. APX809-29SAG-7, ADM809SARTZ-REEL7, and MAX809 series parts specify 140ms minimum reset timeout, which is functionally compatible with applications designed for 100ms timeout. The longer timeout provides additional margin in reset sequencing.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 Compliant status, matching the original AP1701EWL-7 specification.

Q: Which substitute supports the widest operating temperature range?

A: ADM809SARTZ-REEL7 supports -40°C ~ 125°C operating temperature, the widest range among all listed substitutes. MAX809SEUR+, MAX809SEUR+T, and MAX809SEUR+T10 support -40°C ~ 105°C.

Q: What is MSL rating and why does it matter?

A: Moisture Sensitivity Level (MSL) indicates the maximum time a component can be exposed to moisture before soldering. MSL-1 (Unlimited) parts have no time restriction and are preferred for inventory management and production flexibility. The original AP1701EWL-7 carries MSL-3 (168 Hours), while all active substitutes carry MSL-1.

Q: Can MAX809SN293D1T1G be used despite its Obsolete status?

A: MAX809SN293D1T1G meets all electrical and mechanical parameters (2.93V threshold, push-pull totem pole output, SOT-23-3 package, ROHS3 compliant). However, its Obsolete product status indicates discontinued manufacturing. Use only if existing inventory is available and long-term supply is not required.
