Substitute Part Grouping Explanation

Substitute parts for the 74AUP1G02FS3-7 are qualified based on the following criteria:

Functional Equivalence: All substitute parts implement the same logic function (single-channel NOR gate with 2 inputs) and share the identical base product number 74AUP1G02.

Electrical Parameters: Substitute parts maintain identical electrical specifications including supply voltage range (0.8V ~ 3.6V), quiescent current (500 nA max), output current (4mA, 4mA), input logic levels, and propagation delay (6.4ns @ 3.3V, 30pF).

Compliance & Certifications: All substitute parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) rating, ensuring equivalent environmental and regulatory compliance.

Package Compatibility Consideration: While all parts are surface mount with exposed pad configurations, physical package dimensions vary (X2-DFN0808-4, 4-X2SON, 5-X2SON). Package selection depends on PCB layout and assembly process requirements.

Operating Temperature Range: The main part operates -40°C ~ 125°C. One substitute (SN74AUP1G02DPWR) operates -40°C ~ 85°C, which is a narrower range suitable for applications not requiring the full temperature specification.

Parameter Comparison

Engineering Selection Recommendations

All three parts are active products with ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current and future applications.

74AUP1G02FS3-7 (Diodes Incorporated): Primary selection for applications requiring full operating temperature range (-40°C ~ 125°C) with X2-DFN0808-4 package footprint. Inventory availability: 15,200 pcs.

SN74AUP1G02DPWR (Texas Instruments): Suitable for applications with operating temperature requirements limited to -40°C ~ 85°C. Offers 4-X2SON package alternative. Inventory availability: 6,814 pcs.

74AUP1G02GX,125 (Nexperia USA Inc.): Recommended for full operating temperature range (-40°C ~ 125°C) applications with 5-X2SON package requirement. Inventory availability: 10,730 pcs.

Selection between substitute parts is determined by package footprint compatibility with PCB design and operating temperature requirements of the end application.

Frequently Asked Questions (FAQ)

Q: Are all three parts electrically interchangeable? A: Yes. All parts share identical electrical specifications including supply voltage (0.8V ~ 3.6V), quiescent current (500 nA max), output current (4mA, 4mA), input logic levels, and propagation delay (6.4ns @ 3.3V, 30pF). Electrical interchangeability is confirmed across all parameters.

Q: What is the primary difference between these substitute parts? A: The primary differences are package configuration and operating temperature range. The SN74AUP1G02DPWR operates at -40°C ~ 85°C (narrower range), while 74AUP1G02FS3-7 and 74AUP1G02GX,125 both operate at -40°C ~ 125°C. Package types differ: X2-DFN0808-4, 4-X2SON, and 5-X2SON respectively.

Q: Can I use SN74AUP1G02DPWR in an application requiring -40°C ~ 125°C operation? A: No. The SN74AUP1G02DPWR is specified for -40°C ~ 85°C operation only. For applications requiring full -40°C ~ 125°C temperature range, use 74AUP1G02FS3-7 or 74AUP1G02GX,125.

Q: Are there package footprint compatibility concerns? A: Yes. The three parts use different surface mount packages: X2-DFN0808-4, 4-X2SON (0.8x0.8), and 5-X2SON (0.80x0.80). PCB layout and assembly equipment must support the selected package type. Footprint verification is required before substitution.

Q: Do all parts meet the same compliance standards? A: Yes. All three parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) rating. Compliance and environmental certifications are equivalent across all substitute options.

Q: Which part should I select for new designs? A: Selection depends on two factors: (1) operating temperature requirement of your application, and (2) package footprint compatibility with your PCB design. For full temperature range (-40°C ~ 125°C), choose between 74AUP1G02FS3-7 or 74AUP1G02GX,125 based on package availability and PCB layout requirements.
