APX810S-44SA-7 Equivalent & Substitute Parts

Part Overview

The APX810S-44SA-7 is a single-channel power management supervisor IC manufactured by Diodes Incorporated. This device functions as a reset/power-on reset controller with push-pull totem pole output configuration, housed in a SOT-23-3 surface mount package. The part is currently active in production with 21,200 units in stock inventory. Substitute parts are identified when equivalent electrical parameters and mechanical compatibility are maintained across the specified operating conditions and package specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the APX810S-44SA-7 are qualified based on strict parameter equivalence in the following categories:

Electrical Parameters: Voltage threshold (4.38V), output configuration (push-pull totem pole), reset logic (active high), and reset timeout (140ms minimum) must be identical.

Mechanical Compatibility: Package type (SOT-23-3), mounting method (surface mount), and pin configuration must match the original specification.

Environmental & Compliance: Operating temperature range (-40°C ~ 125°C), RoHS3 compliance, MSL rating (1), and REACH status must be equivalent or superior.

Functional Classification: All substitutes are single-channel power-on reset supervisors with identical functional topology.

Three parametric equivalents meet these criteria: APX810S-44SR-7 (Diodes Incorporated), ADM810MARTZ-REEL7 (Analog Devices Inc.), and TCM810MVNB713 (Microchip Technology).

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts maintain full electrical and mechanical equivalence to the APX810S-44SA-7. Selection between these options is determined by availability, packaging format preference, and supply chain requirements.

APX810S-44SR-7 (Diodes Incorporated) provides the highest inventory availability at 15,400 units and maintains identical manufacturer sourcing with tape & reel packaging. This option minimizes supply chain transition risk.

ADM810MARTZ-REEL7 (Analog Devices Inc.) is available in cut tape format with 3,300 units in stock. This packaging option is suitable for lower-volume applications or manual assembly processes.

TCM810MVNB713 (Microchip Technology) offers 4,200 units in tape & reel format. This option provides manufacturer diversity while maintaining all specified electrical and compliance parameters.

All three parts are active products with ROHS3 compliance, REACH unaffected status, and identical functional specifications. Selection should be based on procurement lead time, packaging requirements, and cost considerations.

Frequently Asked Questions (FAQ)

Q: Can APX810S-44SR-7 be used as a direct replacement for APX810S-44SA-7?

A: Yes. Both parts are manufactured by Diodes Incorporated and share identical electrical parameters, package type (SOT-23-3), voltage threshold (4.38V), output configuration (push-pull totem pole), reset logic (active high), and operating temperature range (-40°C ~ 125°C). The only difference is packaging format (both tape & reel).

Q: What is the difference between tape & reel (TR) and cut tape (CT) packaging?

A: Tape & reel packaging is supplied on continuous carrier tape wound on reels, suitable for automated pick-and-place assembly. Cut tape packaging is supplied in shorter tape segments, typically used for lower-volume applications or manual assembly. Both formats contain identical components with the same electrical specifications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. APX810S-44SA-7, APX810S-44SR-7, ADM810MARTZ-REEL7, and TCM810MVNB713 are all ROHS3 compliant with MSL rating of 1 (unlimited moisture sensitivity level).

Q: Can I mix manufacturers in the same assembly?

A: Yes. All three substitute manufacturers (Diodes Incorporated, Analog Devices Inc., and Microchip Technology) provide functionally equivalent parts with identical electrical parameters, package specifications, and compliance certifications. Pin configuration and functional behavior are identical across all options.

Q: What does "Active High" reset logic mean?

A: Active High reset logic indicates that the reset output is asserted (driven high) when a power supply voltage falls below the 4.38V threshold. The output returns to inactive state when voltage rises above the threshold and the 140ms minimum timeout period expires.

Q: Are there any temperature or environmental restrictions for these parts?

A: All substitute parts operate across the identical temperature range of -40°C to 125°C (TA). All parts have MSL rating of 1, indicating unlimited moisture sensitivity level with no special storage or handling requirements beyond standard component handling practices.
