74LVC1G02FS3-7 Equivalent & Substitute Parts

Part Overview

The 74LVC1G02FS3-7 is a single-channel NOR gate logic IC manufactured by Diodes Incorporated, designed for low-voltage digital applications. This component operates across a wide supply voltage range of 1.65V to 5.5V and features a 2-input configuration in a compact 4-XFDFN Exposed Pad package. The part maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating, making it suitable for industrial and commercial applications requiring reliable logic gating functionality.

Substitute parts are identified when equivalent logic functionality, electrical performance parameters, and physical packaging compatibility can be maintained across different manufacturers while preserving circuit operation and reliability standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 74LVC1G02FS3-7 is determined by the following critical parameters:

Logic configuration must remain a single-channel, 2-input NOR gate to maintain functional equivalence. Supply voltage range must encompass or match the 1.65V to 5.5V specification to ensure operation across intended applications. Operating temperature range must cover -40°C to 125°C to preserve reliability in target environments. Package type must be compatible with surface mount assembly processes and PCB footprint requirements. All substitute parts must maintain Active product status and RoHS3 compliance to meet current manufacturing and environmental standards.

The SN74LVC1G02DPWR from Texas Instruments satisfies these substitution criteria through identical logic configuration, matching supply voltage range, equivalent operating temperature specification, compatible surface mount packaging, and equivalent compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both the 74LVC1G02FS3-7 and SN74LVC1G02DPWR maintain Active product status, ensuring long-term availability and manufacturing support. Both components carry ROHS3 compliance and unlimited moisture sensitivity ratings, meeting current environmental and reliability standards for industrial applications.

The primary distinction between these parts lies in quiescent current consumption and propagation delay characteristics. The 74LVC1G02FS3-7 specifies a maximum quiescent current of 200 µA with a propagation delay of 1.7ns at 5V with 50pF load. The SN74LVC1G02DPWR specifies a maximum quiescent current of 10 µA with a propagation delay of 4.5ns under identical conditions. Selection between these parts depends on application requirements for power consumption versus speed performance.

Frequently Asked Questions (FAQ)

Q: Can the SN74LVC1G02DPWR directly replace the 74LVC1G02FS3-7 in existing designs?

A: Direct substitution is possible when circuit timing requirements accommodate the SN74LVC1G02DPWR's 4.5ns propagation delay compared to the 74LVC1G02FS3-7's 1.7ns specification. Both parts share identical supply voltage ranges, input/output logic levels, output current ratings, and operating temperature specifications. Package compatibility must be verified for PCB footprint alignment.

Q: What are the key electrical differences between these substitute parts?

A: The primary electrical differences are quiescent current consumption (200 µA for 74LVC1G02FS3-7 versus 10 µA for SN74LVC1G02DPWR) and maximum propagation delay (1.7ns versus 4.5ns at 5V, 50pF load). All other electrical parameters, including supply voltage range, input/output logic levels, and output drive capability, are equivalent.

Q: Are both parts suitable for battery-powered applications?

A: The SN74LVC1G02DPWR is more suitable for battery-powered applications due to its significantly lower quiescent current of 10 µA compared to the 74LVC1G02FS3-7's 200 µA specification. This difference becomes material in applications requiring extended battery life.

Q: Do both parts require identical PCB layout considerations?

A: Both parts use the 4-XFDFN Exposed Pad package with identical physical dimensions and pin configurations. PCB layout requirements for power supply decoupling, signal routing, and thermal management are equivalent between the two parts.

Q: What compliance certifications apply to both substitute parts?

A: Both the 74LVC1G02FS3-7 and SN74LVC1G02DPWR carry ROHS3 compliance, REACH Unaffected status, and EAR99 export classification. Both maintain unlimited moisture sensitivity rating (MSL 1), eliminating special storage or handling requirements.
