Substitute Part Grouping Explanation

Substitute parts for the APX803L-30SA-7 are identified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

• Single-channel voltage monitoring capability
• 3V voltage threshold setting
• Open drain or open collector output configuration
• Active low reset logic
• Operating temperature range of -40°C to 85°C
• Surface mount packaging in SOT-23 form factor variants
• Active product status with current manufacturing availability
• ROHS3 compliance and equivalent regulatory certifications

The TC54VN3002ECB713 from Microchip Technology meets all these criteria and is classified as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the APX803L-30SA-7 and TC54VN3002ECB713 are active products with equivalent electrical specifications and regulatory compliance. Selection between these parts should be based on:

• Inventory availability and lead time requirements
• Packaging format preference (Tape & Reel versus Cut Tape & Digi-Reel)
• Supplier relationship and pricing structure
• Design documentation and reference schematic requirements

Both parts satisfy identical functional requirements for single-channel 3V threshold voltage supervision with active low reset output in SOT-23 surface mount packaging.

Frequently Asked Questions (FAQ)

Q: Can TC54VN3002ECB713 directly replace APX803L-30SA-7 in existing designs?

A: Yes. Both parts share identical electrical parameters including voltage threshold, output configuration, reset logic, and operating temperature range. The SOT-23-3 package footprint is compatible between both devices.

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

A: Both designations refer to the same three-pin surface mount package form factor. SOT-23A-3 is an alternative naming convention used by some manufacturers. The physical dimensions and pin configuration are equivalent.

Q: Are there any compliance differences between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and classified under the same ECCN (EAR99) and HTSUS (8542.39.0001) codes.

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

A: The reset output is held low (logic 0) during normal operation and transitions high (logic 1) when a reset condition is triggered by the voltage threshold being crossed.

Q: Can these parts be used interchangeably in production?

A: Yes, provided that the design accommodates the specified packaging format. Both parts are functionally equivalent for the 3V single-channel voltage supervision application.
