SN74LVC2G02YEPR Equivalent & Substitute Parts

Part Overview

The SN74LVC2G02YEPR is a NOR Gate IC with 2 channels and 2 inputs per channel, manufactured by Texas Instruments in the 74LVC logic series. This dual 2-input NOR gate is housed in an 8-DSBGA (1.9x0.9mm) surface mount package. The part is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement continuity.

Substitute Part Grouping Explanation

Substitution for the SN74LVC2G02YEPR is determined by strict equivalence across the following electrical and mechanical parameters:

Logic function: NOR Gate with identical circuit count (2) and input count (2)
Electrical specifications: Supply voltage range, quiescent current, output current, input logic levels, and propagation delay must be identical
Operating temperature range: -40°C ~ 125°C
Base product number: 74LVC2G02
Mounting type: Surface Mount
Package family: 8-XFBGA or 8-DSBGA variants

Substitute parts SN74LVC2G02YEAR and SN74LVC2G02YZPR meet all electrical equivalence criteria. Differences are limited to packaging format (Cut Tape vs. Tape & Reel) and product status (Obsolete vs. Active).

Engineering Selection Recommendations

For applications requiring the SN74LVC2G02YEPR, the following selection criteria apply:

SN74LVC2G02YZPR is the primary substitute. This part maintains active product status with Texas Instruments, ensuring long-term availability and supply chain stability. It carries ROHS3 compliance and is supplied in Tape & Reel format, standard for production volume applications. All electrical parameters and operating characteristics are identical to the main part.

SN74LVC2G02YEAR is an alternative substitute with identical electrical specifications. However, this part retains obsolete status and carries RoHS non-compliance designation. Selection of this part should be limited to applications where RoHS compliance is not a requirement and where Cut Tape packaging format is preferred for lower-volume or prototype applications.

Both substitutes are electrically and functionally interchangeable with the SN74LVC2G02YEPR within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can SN74LVC2G02YZPR be used as a direct replacement for SN74LVC2G02YEPR?

A: Yes. Both parts are electrically identical across all specified parameters including logic function, supply voltage range, quiescent current, output current, input logic levels, propagation delay, and operating temperature. The only differences are product status (Active vs. Obsolete) and packaging format (Tape & Reel vs. standard).

Q: What is the difference between the 8-DSBGA and 8-XFBGA package variants?

A: Both package variants are listed for these parts and are mechanically and electrically compatible. The 8-DSBGA (1.9x0.9mm) and 8-XFBGA are BGA package families with identical pin configurations and electrical performance. Selection between variants depends on PCB design and assembly process capabilities.

Q: Why is SN74LVC2G02YEAR marked as RoHS non-compliant?

A: RoHS compliance status is a regulatory and manufacturing designation. SN74LVC2G02YEAR does not meet ROHS3 standards, while SN74LVC2G02YZPR does. For applications subject to RoHS requirements, SN74LVC2G02YZPR is the appropriate selection.

Q: Does product status (Active vs. Obsolete) affect electrical performance?

A: No. Product status indicates manufacturing and support lifecycle only. Electrical specifications, performance characteristics, and functional behavior are identical between active and obsolete parts within the same base product number.

Q: What packaging formats are available for these substitutes?

A: SN74LVC2G02YEPR is supplied in standard packaging. SN74LVC2G02YEAR is available in Cut Tape (CT) format for lower-volume applications. SN74LVC2G02YZPR is supplied in Tape & Reel (TR) format, standard for production manufacturing.
