74LVC2G86RA3-7 Equivalent & Substitute Parts

Part Overview

The 74LVC2G86RA3-7 is a dual 2-input XOR (Exclusive OR) logic gate IC manufactured by Diodes Incorporated. This component operates across a wide supply voltage range of 1.65V to 5.5V and is designed for low-power digital logic applications. The part is currently in active production status and is RoHS3 compliant. Substitute parts are necessary when the primary package variant (X2-DFN1210-8) is unavailable or when alternative package geometries are required for specific PCB layout constraints.

Key Parameters

Substitute Part Grouping Explanation

All substitute parts for the 74LVC2G86RA3-7 maintain identical electrical performance specifications. Substitution is determined by the following critical parameters that remain constant across all variants:

• Logic Type: XOR (Exclusive OR)
• Number of Circuits: 2
• Number of Inputs: 2
• Voltage Supply Range: 1.65V ~ 5.5V
• Quiescent Current: 40 µA maximum
• Output Current: 32mA (high and low)
• Propagation Delay: 5.6ns @ 5V, 50pF
• Operating Temperature Range: -40°C ~ 125°C
• Package Family: 8-XFDFN

The primary difference between substitute parts is the physical package variant (DFN1210-8, DFN1410-8, or DFN2010-8), which affects PCB footprint dimensions while maintaining electrical equivalence and the same pin configuration.

Parameter Comparison

Engineering Selection Recommendations

All three parts (74LVC2G86RA3-7, 74LVC2G86HD4-7, and 74LVC2G86HK3-7) are manufactured by Diodes Incorporated and maintain active product status. Each part carries ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements. Selection between these parts should be based solely on PCB layout requirements and available footprint space, as the electrical performance and functional characteristics are identical. The choice of package variant (DFN1210-8, DFN1410-8, or DFN2010-8) does not affect circuit performance or compatibility with the application design.

Frequently Asked Questions (FAQ)

Q: Can 74LVC2G86HD4-7 be used as a direct replacement for 74LVC2G86RA3-7?

A: Yes. Both parts are electrically equivalent with identical logic function, voltage specifications, current ratings, and propagation delay. The difference is the physical package footprint (DFN2010-8 versus DFN1210-8). PCB layout compatibility must be verified before substitution.

Q: What is the difference between the three substitute parts?

A: The three parts differ only in package geometry. 74LVC2G86RA3-7 uses DFN1210-8, 74LVC2G86HK3-7 uses DFN1410-8, and 74LVC2G86HD4-7 uses DFN2010-8. All maintain the same 8-pin configuration and electrical specifications.

Q: Are all substitute parts RoHS compliant?

A: Yes. All three parts are ROHS3 compliant and REACH unaffected, meeting current environmental regulations.

Q: What determines whether a part can substitute for the 74LVC2G86RA3-7?

A: Substitution is determined by matching logic type (XOR), circuit count (2), input count (2), voltage range (1.65V ~ 5.5V), current specifications, propagation delay, and operating temperature range. Package variant differences do not affect electrical substitution capability.

Q: Can I use 74LVC2G86HK3-7 if my PCB is designed for 74LVC2G86RA3-7?

A: Only if the DFN1410-8 footprint is compatible with your PCB layout. Verify footprint dimensions and pin spacing before substitution.
