Substitute Part Grouping Explanation

Substitute parts for the 74LVC2G86HD4-7 are classified based on electrical parameter equivalence and functional compatibility. All identified substitutes maintain identical logic functionality (XOR gate), circuit count (2 channels), input configuration (2 inputs per channel), and critical electrical specifications including supply voltage range, quiescent current, output drive capability, and operating temperature range.

The primary distinction among substitutes lies in packaging format and physical dimensions. The 74LVC2G86HD4-7 uses an X2-DFN2010-8 package, while alternatives employ X2-DFN1410-8, X2-DFN1210-8, or 8-XSON packages. These packaging variations allow selection based on PCB layout constraints and manufacturing capabilities while preserving full electrical interchangeability.

Engineering Selection Recommendations

All substitute parts listed maintain active product status and full ROHS3 compliance with MSL 1 rating, ensuring compatibility with standard manufacturing and assembly processes. Selection among substitutes should be based on packaging requirements and PCB layout constraints.

The 74LVC2G86HK3-7 and 74LVC2G86RA3-7 are parametrically equivalent to the primary part, differing only in package footprint dimensions (X2-DFN1410-8 and X2-DFN1210-8 respectively). These options are suitable when space constraints require smaller package geometries.

The 74LVC2G86GT,115 from Nexperia USA Inc. offers superior propagation delay performance (3.6ns versus 5.6ns) and reduced quiescent current (4 µA versus 40 µA), with an 8-XSON package format. This part is appropriate for applications prioritizing speed performance or low-power operation.

Frequently Asked Questions (FAQ)

Q: Can 74LVC2G86HK3-7 be used as a direct replacement for 74LVC2G86HD4-7?

A: Yes. Both parts are manufactured by Diodes Incorporated and share identical electrical specifications. The difference is package format: X2-DFN2010-8 versus X2-DFN1410-8. PCB layout and footprint compatibility must be verified before substitution.

Q: What is the primary difference between the Diodes and Nexperia versions?

A: The Nexperia 74LVC2G86GT,115 provides faster propagation delay (3.6ns versus 5.6ns) and lower quiescent current (4 µA versus 40 µA). All other electrical parameters remain equivalent. The package format differs: 8-XSON versus X2-DFN variants.

Q: Are all substitutes RoHS compliant?

A: Yes. All listed parts are ROHS3 compliant with MSL 1 rating, suitable for standard lead-free assembly processes.

Q: Which substitute offers the smallest footprint?

A: The 74LVC2G86RA3-7 uses the X2-DFN1210-8 package, representing the smallest footprint among Diodes variants. The Nexperia 74LVC2G86GT,115 with 8-XSON package provides an alternative compact option.

Q: Can substitutes be mixed in the same design?

A: Yes, provided PCB layout accommodates multiple package formats and design timing margins account for propagation delay variations (3.6ns to 5.6ns range).
