Substitute Part Grouping Explanation

Substitution eligibility for the SN74LVC2G86DCUTG4 is determined by the following critical parameters:

Logic Type: XOR (Exclusive OR) with 2 channels and 2 inputs per channel
Supply Voltage Range: 1.65V ~ 5.5V
Output Current Capability: 32mA high and low
Propagation Delay: 3.6ns @ 5V, 50pF
Operating Temperature Range: -40°C ~ 125°C
Surface Mount Configuration
RoHS3 Compliance

Substitute parts are grouped into two categories:

Category 1: Direct Parametric Equivalents (Texas Instruments 74LVC2G86 Series) Parts SN74LVC2G86DCUT and SN74LVC2G86DCUR maintain identical electrical specifications and differ only in packaging format (Cut Tape vs. Digi-Reel). These are functionally interchangeable with the original part.

Category 2: Parametric Equivalents with Package Variation (Nexperia 74LVC2G86 Series) Parts 74LVC2G86DP,125 and 74LVC2G86DC,125 provide equivalent XOR logic functionality with identical electrical performance but use 8-TSSOP and 8-VSSOP packages respectively. Quiescent current is lower (4 µA vs. 10 µA).

Category 3: Cross-Manufacturer Equivalent (onsemi 7WZ Series) Part NC7WZ86K8X provides XOR logic functionality with superior quiescent current (1 µA) and operates within the same voltage and output current specifications. Operating temperature range is limited to -40°C ~ 85°C.

Engineering Selection Recommendations

Primary Recommendation: SN74LVC2G86DCUT or SN74LVC2G86DCUR

These Texas Instruments parts are direct functional replacements with identical electrical specifications and package dimensions. Both are active products with full availability. Selection between DCUT (Cut Tape) and DCUR (Digi-Reel) depends on procurement volume and handling requirements. Both maintain the original -40°C ~ 125°C operating temperature range and 10 µA quiescent current specification.

Secondary Recommendation: 74LVC2G86DC,125 (Nexperia)

This part provides equivalent XOR logic functionality in the same 8-VFSOP package with improved quiescent current (4 µA). It is suitable for applications where lower power consumption is beneficial and the original manufacturer is not a constraint. Operating temperature range remains -40°C ~ 125°C.

Alternative Recommendation: 74LVC2G86DP,125 (Nexperia)

This part uses an 8-TSSOP package (0.118", 3.00mm width) instead of 8-VFSOP. It provides equivalent electrical performance with lower quiescent current (4 µA). PCB layout modification is required due to package footprint difference. Operating temperature range is -40°C ~ 125°C.

Cross-Manufacturer Option: NC7WZ86K8X (onsemi)

This part offers superior quiescent current (1 µA) and maintains equivalent XOR logic functionality. The operating temperature range is limited to -40°C ~ 85°C, which may restrict use in high-temperature applications. Propagation delay is slightly higher at 4.2ns. This option is suitable for low-power applications within the specified temperature range.

All substitute parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, matching the original part's compliance profile.

Frequently Asked Questions (FAQ)

Q: Can SN74LVC2G86DCUT be used as a direct replacement for SN74LVC2G86DCUTG4?

A: Yes. SN74LVC2G86DCUT is a direct functional replacement with identical electrical specifications, package dimensions, and operating temperature range. The difference is in packaging format (Cut Tape vs. the original tube/tray format). Both are 8-VFSOP packages with 0.091" width and 2.30mm dimensions.

Q: What is the difference between SN74LVC2G86DCUT and SN74LVC2G86DCUR?

A: Both parts are electrically identical. DCUT is supplied in Cut Tape format, while DCUR is supplied on Digi-Reel. Selection depends on procurement volume and handling preferences. DCUR typically accommodates higher volume automated assembly.

Q: Can I use 74LVC2G86DP,125 (Nexperia) as a substitute?

A: Yes, with PCB layout modification. The 74LVC2G86DP,125 uses an 8-TSSOP package (0.118", 3.00mm width) instead of 8-VFSOP (0.091", 2.30mm width). Electrical performance is equivalent, but the footprint is different. Quiescent current is lower at 4 µA.

Q: What is the key difference between NC7WZ86K8X and the Texas Instruments alternatives?

A: NC7WZ86K8X offers significantly lower quiescent current (1 µA vs. 10 µA for TI parts). However, the operating temperature range is limited to -40°C ~ 85°C compared to -40°C ~ 125°C for TI and Nexperia parts. Propagation delay is slightly higher at 4.2ns. This part is suitable for low-power applications within the specified temperature range.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, matching the original SN74LVC2G86DCUTG4 compliance profile.

Q: Which substitute part has the lowest power consumption?

A: NC7WZ86K8X has the lowest quiescent current at 1 µA. Nexperia parts (74LVC2G86DP,125 and 74LVC2G86DC,125) have 4 µA quiescent current. Texas Instruments parts (SN74LVC2G86DCUT and SN74LVC2G86DCUR) have 10 µA quiescent current.

Q: Can I use these parts interchangeably on the same PCB?

A: SN74LVC2G86DCUT, SN74LVC2G86DCUR, and 74LVC2G86DC,125 use the same 8-VFSOP package and are PCB-compatible. The 74LVC2G86DP,125 uses 8-TSSOP and requires footprint modification. NC7WZ86K8X uses 8-VFSOP but may require thermal or layout considerations due to different manufacturer specifications.

Q: What is the supply voltage range for all substitute parts?

A: All substitute parts operate within 1.65V ~ 5.5V supply voltage range, matching the original SN74LVC2G86DCUTG4 specification.
