Substitute Part Grouping Explanation

Substitute parts for the 74AUP1G04FS3-7 are classified based on electrical and mechanical compatibility within the 74AUP inverter family. All identified substitutes maintain identical logic functionality, electrical performance specifications, and supply voltage range. Substitution eligibility is determined by the following criteria:

Identical logic type (Inverter), circuit count (1), and input count (1)
Matching voltage supply range (0.8V ~ 3.6V)
Identical quiescent current specification (500 nA maximum)
Matching output current ratings (4mA high and low)
Identical input logic level thresholds
Equivalent propagation delay performance (5.4ns @ 3.3V, 30pF)
Surface mount packaging with compatible pinout
Active product status with ROHS3 compliance and REACH unaffected designation

Substitute parts are differentiated by manufacturer and package variant (X2-DFN vs. X2SON configurations), which may affect PCB layout and assembly considerations but do not alter electrical substitutability.

Engineering Selection Recommendations

All three parts—74AUP1G04FS3-7, SN74AUP1G04DPWR, and 74AUP1G04GX,125—are active products with ROHS3 compliance and REACH unaffected status, making them suitable for current design implementations and regulatory requirements.

The SN74AUP1G04DPWR (Texas Instruments) operates within a reduced temperature range (-40°C ~ 85°C) compared to the primary part and Nexperia alternative, which both support -40°C ~ 125°C. Selection of the Texas Instruments part requires verification that the application's maximum operating temperature does not exceed 85°C.

The 74AUP1G04GX,125 (Nexperia) and 74AUP1G04FS3-7 (Diodes) both support the full -40°C ~ 125°C temperature range and are electrically identical. Package configuration differences (X2-DFN0808-4 vs. 5-X2SON) may influence PCB layout and assembly process compatibility but do not affect electrical performance or functional substitutability.

Frequently Asked Questions (FAQ)

Q: Can the SN74AUP1G04DPWR replace the 74AUP1G04FS3-7 in all applications?

A: The SN74AUP1G04DPWR is electrically equivalent for all specified parameters. However, its operating temperature range is limited to -40°C ~ 85°C, whereas the primary part supports -40°C ~ 125°C. Applications requiring operation above 85°C must use the 74AUP1G04FS3-7 or 74AUP1G04GX,125.

Q: What is the difference between the X2-DFN0808-4 and X2SON packages?

A: Both packages are surface-mount configurations with 0.8mm x 0.8mm footprints. The primary difference is the package designation and potential lead frame geometry. PCB layout and assembly equipment compatibility should be verified for the specific package variant selected.

Q: Are all three parts ROHS3 compliant?

A: Yes. The 74AUP1G04FS3-7, SN74AUP1G04DPWR, and 74AUP1G04GX,125 are all ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: Which substitute part has the best inventory availability?

A: The 74AUP1G04FS3-7 (Diodes Incorporated) has the highest inventory at 3,980 units, followed by SN74AUP1G04DPWR (Texas Instruments) at 3,924 units, and 74AUP1G04GX,125 (Nexperia) at 2,127 units.

Q: Do all parts have identical electrical performance?

A: Yes. All three parts share identical specifications for voltage supply range, quiescent current, output current, input logic levels, and propagation delay. The only electrical difference is the operating temperature range of the Texas Instruments part.
