74HC2G86GD,125 Equivalent & Substitute Parts

Part Overview

The 74HC2G86GD,125 is a dual 2-input XOR (Exclusive OR) logic gate IC manufactured by Nexperia USA Inc. in an 8-XSON (2x3) surface mount package. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and production continuity. The XOR logic function remains critical in digital circuit applications including parity generation, binary comparison, and arithmetic operations. Substitute parts must maintain identical electrical performance and logic functionality while accommodating alternative packaging formats.

Substitute Part Grouping Explanation

Substitution of the 74HC2G86GD,125 is based on strict equivalence of the following electrical and functional parameters:

Logic function: Dual 2-input XOR gate
Supply voltage range: 2V ~ 6V
Quiescent current: 1 µA maximum
Output drive capability: 5.2mA high and low
Input logic thresholds: 0.5V ~ 1.8V (low), 1.5V ~ 4.2V (high)
Propagation delay: 17ns @ 6V, 50pF load
Operating temperature: -40°C ~ 125°C
Series designation: 74HC
Base product number: 74HC2G86

The 74HC2G86DC,125 qualifies as a direct substitute based on identical electrical specifications and logic functionality. The primary difference is packaging format: the substitute uses 8-VSSOP instead of 8-XSON, with corresponding changes to physical dimensions and tape & reel delivery format.

Engineering Selection Recommendations

The 74HC2G86DC,125 is the qualified substitute for the obsolete 74HC2G86GD,125. Both parts are manufactured by Nexperia USA Inc. and share identical electrical specifications, logic functionality, and operating characteristics. The substitute maintains full ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity.

Selection of the substitute should account for package footprint differences. The main part uses 8-XSON (2x3) packaging, while the substitute uses 8-VSSOP with different physical dimensions (0.091", 2.30mm width). PCB layout and land pattern modifications are required for implementation. The substitute's active product status ensures long-term availability and supply chain stability compared to the obsolete main part.

Frequently Asked Questions (FAQ)

Q: Are the 74HC2G86GD,125 and 74HC2G86DC,125 electrically interchangeable?

A: Yes. Both parts are identical in electrical performance, logic function, supply voltage range, output drive capability, propagation delay, and operating temperature. They differ only in physical package format and delivery method.

Q: What is the primary difference between these two parts?

A: The main difference is packaging. The 74HC2G86GD,125 uses 8-XSON (2x3) format, while the 74HC2G86DC,125 uses 8-VSSOP format. This affects PCB footprint, land pattern design, and component placement. The substitute is supplied in tape & reel format versus bulk packaging.

Q: Can I use the 74HC2G86DC,125 as a direct replacement on existing PCBs designed for the 74HC2G86GD,125?

A: No. The different package formats require PCB redesign. The 8-VSSOP package has different pin spacing and physical dimensions than the 8-XSON package. A new PCB layout with updated land patterns is necessary.

Q: Why is the 74HC2G86GD,125 listed as obsolete?

A: The main part is classified as obsolete by the manufacturer. The 74HC2G86DC,125 substitute is active and represents the current production alternative for this XOR logic function.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity levels (MSL 1 - Unlimited). Regulatory and environmental compliance is maintained with the substitute.

Q: What is the inventory status of the substitute?

A: The 74HC2G86DC,125 has 3993 pieces in stock as new original inventory, providing immediate availability for production requirements.
