Substitute Part Grouping Explanation

Substitute parts for the APX809S00-29SR-7 are qualified based on strict equivalence across the following critical parameters:

• Voltage threshold monitoring: 2.93V
• Output type: Push-Pull, Totem Pole configuration
• Reset logic: Active Low
• Reset timeout: 1ms Minimum
• Package specification: SOT-23-3 (TO-236-3, SC-59)
• Surface mount mounting type
• Operating temperature range: -40°C ~ 125°C
• Single-channel voltage monitoring architecture
• Base product series: APX809

The APX809S00-29SA-7 meets all these criteria and is classified as a parametric equivalent. The substitution is based on identical electrical specifications, package compatibility, and functional equivalence in reset/power-on reset supervision applications.

Parameter Comparison

Engineering Selection Recommendations

Both the APX809S00-29SR-7 and APX809S00-29SA-7 are active production parts from Diodes Incorporated with identical electrical and mechanical specifications. Selection between these parts should be based on availability and supply chain requirements. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility in applications requiring environmental compliance. The APX809S00-29SA-7 currently has higher inventory availability (17,200 units) compared to the APX809S00-29SR-7 (785 units), which may influence procurement decisions for high-volume production requirements.

Frequently Asked Questions (FAQ)

Q: Can APX809S00-29SA-7 be used as a direct replacement for APX809S00-29SR-7?

A: Yes. Both parts are parametric equivalents with identical voltage threshold (2.93V), output configuration (push-pull totem pole), reset logic (active low), reset timeout (1ms minimum), and SOT-23-3 package specification. No circuit modifications are required.

Q: Are there any differences in the SOT-23-3 package between these parts?

A: No. Both parts use the identical TO-236-3, SC-59, SOT-23-3 package specification with surface mount mounting type. Pin configuration and footprint compatibility are guaranteed.

Q: What is the significance of the different part number suffixes (-29SR-7 vs -29SA-7)?

A: The suffix variation indicates different packaging or tape reel configurations from the manufacturer. The electrical and functional specifications remain identical. Both are supplied in Tape & Reel (TR) packaging.

Q: Are both parts suitable for the full operating temperature range?

A: Yes. Both APX809S00-29SR-7 and APX809S00-29SA-7 operate across the identical temperature range of -40°C to 125°C (TA).

Q: Do these parts require any special handling or storage considerations?

A: Both parts have Moisture Sensitivity Level (MSL) rating of 1 (Unlimited), indicating no special moisture control requirements during storage or handling.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts maintain identical RoHS3 compliance, REACH unaffected status, and ECCN/HTSUS classifications.
