SN74AHC02RGYRG4 Equivalent & Substitute Parts

Part Overview

The SN74AHC02RGYRG4 is a NOR Gate IC featuring 4 channels with 2 inputs per channel in a 14-VQFN (4.6x4.6) surface mount package. This logic component operates across a wide supply voltage range of 2V to 5.5V and is designed for general-purpose digital logic applications requiring low power consumption and fast propagation delays.

The SN74AHC02RGYRG4 is currently discontinued at DiGi Electronics, making it necessary to identify equivalent substitute parts that maintain identical electrical and mechanical specifications for seamless integration into existing designs.

Substitute Part Grouping Explanation

Substitution of the SN74AHC02RGYRG4 is determined by strict equivalence across the following critical parameters:

  • Logic function: NOR Gate with identical 4-channel, 2-input configuration
  • Electrical specifications: Supply voltage range (2V ~ 5.5V), quiescent current (2 µA max), output drive current (8mA), input logic levels, and propagation delay (8.5ns @ 5V, 50pF)
  • Mechanical compatibility: 14-VFQFN Exposed Pad package with identical footprint (4.6x4.6)
  • Environmental compliance: ROHS3 compliance and MSL rating (2, 1 Year)
  • Operating temperature range: -40°C ~ 125°C

The SN74AHC02RGYR meets all these criteria and qualifies as a parametric equivalent. The primary distinction is packaging format: the substitute is supplied in Tape & Reel (TR) format rather than individual packaging, and maintains Active product status.

Engineering Selection Recommendations

The SN74AHC02RGYR is a direct parametric equivalent to the SN74AHC02RGYRG4 and is suitable for component replacement in all applications where the original part was specified. Both parts are manufactured by Texas Instruments, share identical electrical and mechanical specifications, and maintain ROHS3 compliance with equivalent moisture sensitivity ratings.

The primary advantage of selecting SN74AHC02RGYR is its Active product status, ensuring continued availability and supply chain reliability. The Tape & Reel packaging format is standard for high-volume production environments and automated assembly processes.

For applications requiring individual unit packaging or lower-volume procurement, alternative sourcing channels or packaging format conversions may be necessary. However, from an electrical and functional standpoint, no design modifications are required when transitioning from SN74AHC02RGYRG4 to SN74AHC02RGYR.

Frequently Asked Questions (FAQ)

Q: Can SN74AHC02RGYR be used as a direct replacement for SN74AHC02RGYRG4?

A: Yes. Both parts are parametrically identical across all electrical specifications, logic function, operating temperature range, and package footprint. The only difference is the packaging format (Tape & Reel versus individual packaging) and product status (Active versus Discontinued).

Q: What is the difference between the packaging formats?

A: SN74AHC02RGYRG4 is supplied in individual packaging, while SN74AHC02RGYR is supplied in Tape & Reel (TR) format. Tape & Reel packaging is designed for automated pick-and-place assembly and is standard for production environments. Both formats contain identical die and electrical performance.
