Engineering Selection Recommendations

The 74AUP1G86GX,125 from NXP USA Inc. is a direct electrical equivalent to the 74AUP1G86FS3-7. Both parts share identical electrical specifications across all critical parameters including supply voltage, quiescent current, output drive, input thresholds, and propagation delay.

Selection between these parts should be based on:

Packaging requirements: The Diodes part uses X2-DFN0808-4 packaging, while the NXP part uses 5-X2SON (0.80x0.80) packaging. Both maintain the same 4-XFDFN Exposed Pad case designation.
Supply chain availability: The NXP part has significantly higher inventory (80831 units) compared to the Diodes part (794 units).
Compliance requirements: The Diodes part explicitly lists ROHS3 compliance and MSL Level 1. Verify NXP compliance status with the supplier if regulatory documentation is required.
Procurement lead times and cost considerations specific to your supply chain.

Both parts are active production items suitable for new designs and production applications.

Frequently Asked Questions (FAQ)

Q: Are the 74AUP1G86FS3-7 and 74AUP1G86GX,125 pin-compatible?

A: Both parts are based on the 74AUP1G86 base product number and maintain identical electrical specifications. Pin compatibility is confirmed by matching logic function, input/output characteristics, and operating parameters. Verify physical package dimensions against your PCB layout, as the supplier device packages differ (X2-DFN0808-4 vs. 5-X2SON).

Q: Can I substitute the Diodes part with the NXP part in an existing design?

A: Yes, provided your PCB layout accommodates the different supplier device package. Both parts deliver identical electrical performance across all specified parameters and operating conditions.

Q: What is the significance of the different packaging designations?

A: The X2-DFN0808-4 and 5-X2SON (0.80x0.80) are supplier-specific package designations for the same 4-XFDFN Exposed Pad case type. Both are 0.8mm × 0.8mm surface mount packages. Confirm footprint compatibility with your PCB design before substitution.

Q: Are there compliance differences between these parts?

A: The Diodes part explicitly specifies ROHS3 compliance and MSL Level 1 (Unlimited). The NXP part data provided does not include these specifications. If regulatory compliance documentation is required for your application, confirm NXP compliance status directly with the supplier.

Q: Which part should I select for new designs?

A: Both parts are active production items. Selection should be based on packaging compatibility with your PCB layout, compliance requirements, and supply chain availability. The NXP part offers higher inventory availability.
