Substitute Part Grouping Explanation

Substitution of the 74HCT2G86GD,125 is determined by strict equivalence across the following critical parameters:

• Logic function: XOR (Exclusive OR) with identical circuit count (2) and input configuration (2-input)
• Electrical specifications: Supply voltage range (4.5V ~ 5.5V), quiescent current (1 µA max), output drive capability (4mA), input logic thresholds (0.8V low, 2V high), and propagation delay (19ns @ 4.5V, 50pF)
• Environmental compliance: ROHS3 compliance, MSL rating (1), operating temperature range (-40°C ~ 125°C)
• Manufacturing series: 74HCT logic family

The primary distinction between the main part and its substitute lies in packaging format and product status. The 74HCT2G86GD,125 uses 8-XSON (2x3) packaging and is obsolete, while the substitute maintains identical electrical performance in an alternative surface mount package configuration.

Parameter Comparison

Engineering Selection Recommendations

The 74HCT2G86DC,125 is a direct functional equivalent to the 74HCT2G86GD,125 with identical electrical performance across all specified parameters. The substitute part maintains active product status with Nexperia USA Inc., ensuring ongoing availability and supply chain continuity. Both parts satisfy ROHS3 compliance and REACH regulatory requirements.

Selection between these parts is determined by PCB layout constraints and packaging compatibility. The 74HCT2G86GD,125 employs 8-XSON (2x3) packaging, while the 74HCT2G86DC,125 uses 8-VSSOP packaging. Footprint dimensions and land pattern requirements must be verified against design specifications prior to implementation. Both parts are supplied in surface mount format with identical MSL ratings and operating temperature ranges.

Frequently Asked Questions (FAQ)

Q: Can the 74HCT2G86DC,125 replace the 74HCT2G86GD,125 in existing designs?

A: Yes, provided PCB footprint and land pattern accommodate the 8-VSSOP package. Electrical performance is identical across all specified parameters including supply voltage, logic thresholds, propagation delay, and output drive capability.

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

A: The parts differ in packaging format and product status. The 74HCT2G86GD,125 uses 8-XSON (2x3) packaging and is obsolete. The 74HCT2G86DC,125 uses 8-VSSOP packaging and maintains active status.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and carry MSL rating 1 (unlimited moisture sensitivity level).

Q: What are the critical electrical parameters for substitution?

A: XOR logic function, dual 2-input configuration, 4.5V ~ 5.5V supply voltage, 1 µA quiescent current, 4mA output drive, 0.8V/2V input logic thresholds, and 19ns propagation delay at 4.5V with 50pF load.

Q: Are there packaging considerations for board redesign?

A: Yes. The 8-XSON (2x3) and 8-VSSOP packages have different footprints and dimensions. The 8-VFSOP package is 0.091" wide with 2.30mm width specification. PCB layout must be verified for compatibility before implementation.
