74LVC2G86GD,125 Equivalent & Substitute Parts

Part Overview

The 74LVC2G86GD,125 is a dual 2-input XOR (Exclusive OR) logic gate IC manufactured by Nexperia USA Inc. in the 8-XSON (2x3) surface mount package. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and production continuity. The part operates across a wide supply voltage range of 1.65V to 5.5V with low quiescent current and fast propagation delay characteristics suitable for general-purpose logic applications.

Substitute Part Grouping Explanation

Substitution of the 74LVC2G86GD,125 is determined by the following critical parameters:

Logic Function: All substitute parts must implement dual 2-input XOR logic with identical truth table behavior
Electrical Specifications: Supply voltage range, quiescent current, output drive current, propagation delay, and input logic levels must remain constant
Operating Temperature Range: -40°C to 125°C must be maintained
Package Compatibility: Substitutes are grouped by physical package type (8-XSON variants and 8-VSSOP), which determines PCB footprint compatibility
Compliance Standards: RoHS3 compliance and REACH unaffected status must be preserved

The 74LVC2G86 series from Nexperia provides multiple package options within the same electrical specification set. Substitutes are available in three distinct 8-XSON package variants (2x3, 1.2x1, and 1.35x1 dimensions) and one 8-VSSOP package option. All maintain identical electrical performance and functional behavior.

Engineering Selection Recommendations

For Direct Footprint Replacement (8-XSON 2x3 Package)

The 74LVC2G86GD,125 is obsolete. No active substitute exists in the identical 8-XSON (2x3) package footprint. Designs using this specific package must be redesigned to accommodate alternative package options.

For Electrical Equivalence with Package Change

All listed substitute parts maintain identical electrical specifications and functional behavior. Selection depends on PCB layout requirements:

74LVC2G86DC,125: Active status. 8-VSSOP package. Suitable for designs that can accommodate VSSOP footprint.
74LVC2G86GN,115: Active status. 8-XSON (1.2x1) package. Smallest XSON variant. Suitable for space-constrained applications.
74LVC2G86GS,115: Active status. 8-XSON (1.35x1) package. Mid-range XSON variant with highest inventory availability (5828 pcs).
74LVC2G86GT,115: Active status. 8-XSON SOT833-1 (1.95x1) package. Largest XSON variant.

All substitutes are ROHS3 compliant, REACH unaffected, and maintain MSL 1 (unlimited) moisture sensitivity rating.

Frequently Asked Questions (FAQ)

Q: Can the 74LVC2G86GD,125 be directly replaced with another part number without PCB redesign?

A: No. The 74LVC2G86GD,125 is obsolete and no active substitute exists in the identical 8-XSON (2x3) package. PCB layout modification is required to accommodate alternative package options.

Q: Are all substitute parts electrically identical to the original 74LVC2G86GD,125?

A: Yes. All listed substitutes maintain identical electrical specifications including supply voltage range (1.65V ~ 5.5V), quiescent current (4 µA max), output drive current (32mA), propagation delay (3.6ns @ 5V, 50pF), and operating temperature range (-40°C ~ 125°C).

Q: What is the difference between the various 8-XSON package options?

A: The 8-XSON packages differ only in physical dimensions: 2x3mm (original, obsolete), 1.2x1mm (GN,115), 1.35x1mm (GS,115), and 1.95x1mm (GT,115). All are functionally and electrically equivalent. Package selection is determined by available PCB space and manufacturing capabilities.

Q: Which substitute has the best availability?

A: The 74LVC2G86GS,115 in 8-XSON (1.35x1) package has the highest inventory at 5,828 pieces in stock.

Q: Are all substitutes RoHS compliant?

A: Yes. All listed substitutes are ROHS3 compliant and REACH unaffected, matching the compliance status of the original part.

Q: Can I use the 74LVC2G86DC,125 (VSSOP package) as a substitute if my PCB is designed for XSON?

A: No. The VSSOP and XSON packages have different footprints and pin layouts. PCB redesign is required to use the VSSOP variant.
