Substitute Part Grouping Explanation

Substitute parts for the APX809S-26SAG7 are qualified based on strict parametric equivalence across the following criteria:

Voltage threshold matching at 2.63V
Identical output configuration (Push-Pull, Totem Pole)
Active Low reset logic
Minimum reset timeout of 140ms
Operating temperature range of -40°C to 125°C
Surface mount package compatibility (SOT-23-3 / TO-236-3 / SC-59)
Single voltage monitoring channel
ROHS3 compliance and MSL 1 rating

All substitute parts listed maintain these electrical and mechanical specifications, ensuring functional interchangeability in applications designed for the APX809S-26SAG7. Packaging format variations (Tape & Reel vs. Cut Tape) do not affect electrical performance or board-level compatibility.

Engineering Selection Recommendations

All listed substitute parts maintain active product status with ROHS3 compliance and MSL 1 rating, confirming suitability for current manufacturing and assembly processes. Selection between APX809S-26SAG7 and its substitutes should be based on:

Packaging format availability: APX809S-26SAG7 is supplied in standard packaging, while APX809S-26SA-7 and APX809S-26SR-7 are available in Tape & Reel format. ADM809RARTZ-REEL7 is supplied in Cut Tape & Digi-Reel format. TCM809RVNB713 is available in Tape & Reel format.
Inventory availability: ADM809RARTZ-REEL7 offers the highest stock level at 15,003 pieces, followed by APX809S-26SA-7 at 12,300 pieces.
Manufacturer preference: Diodes Incorporated variants (APX809S series) maintain identical base product specifications. Analog Devices (ADM809) and Microchip Technology (TCM809) alternatives provide cross-manufacturer equivalence.

All parts are electrically and mechanically interchangeable for applications requiring 2.63V threshold supervision with push-pull output and 140ms minimum reset timeout.

Frequently Asked Questions (FAQ)

Q: Can APX809S-26SAG7 be directly replaced with APX809S-26SA-7?

A: Yes. Both parts are manufactured by Diodes Incorporated and share identical electrical specifications, voltage threshold, output configuration, and reset timing. The difference is packaging format: APX809S-26SAG7 uses standard packaging while APX809S-26SA-7 is supplied in Tape & Reel format. Board-level functionality is identical.

Q: Are cross-manufacturer substitutes (ADM809RARTZ-REEL7, TCM809RVNB713) fully compatible?

A: Yes. All substitute parts meet the same parametric requirements: 2.63V threshold, push-pull totem pole output, active low reset, 140ms minimum timeout, SOT-23-3 package, and -40°C to 125°C operating range. Cross-manufacturer substitution is valid when these parameters match.

Q: Does packaging format affect electrical performance?

A: No. Tape & Reel, Cut Tape, and standard packaging formats do not alter electrical characteristics or board-level performance. Format selection is determined by assembly equipment compatibility and procurement requirements.

Q: What is the significance of MSL 1 rating?

A: MSL 1 indicates unlimited shelf life and moisture sensitivity, meaning the component does not require special moisture control during storage or handling. This simplifies inventory management and manufacturing logistics.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, provided the design was originally specified for the APX809S-26SAG7 or an equivalent supervisor with matching parameters. All listed substitutes maintain the same electrical interface, pin configuration, and functional behavior.
