Substitute Part Grouping Explanation

Substitute parts for the 74LVC1G86FX4-7 are classified based on electrical and mechanical compatibility. All identified substitutes maintain the core functional parameters: single-channel XOR logic, 2 inputs, supply voltage range of 1.65V to 5.5V, output current capability of 32mA, input logic thresholds, and 4ns maximum propagation delay at 5V with 50pF load. Substitution is determined by equivalence in these critical electrical parameters.

Packaging variations exist among substitutes, with differences in supplier device packages (X2-DFN1010-6, 5-DSBGA, 6-XSON variants) while maintaining the 6-XFDFN case designation. Quiescent current specifications vary among manufacturers: the main part and parametric equivalents specify 200 µA maximum, while direct manufacturer alternatives specify lower values (10 µA for Texas Instruments, 4 µA for Nexperia). Operating temperature ranges differ slightly, with the main part and Nexperia parts rated to 125°C, while the Texas Instruments variant is rated to 85°C.

All substitutes are active products with ROHS3 compliance, MSL 1 rating, and identical ECCN and HTSUS classifications.

Engineering Selection Recommendations

Selection among equivalent and substitute parts is based on electrical compatibility, product status, compliance certifications, and packaging requirements.

All identified substitutes maintain active product status with ROHS3 compliance and MSL 1 rating, ensuring regulatory and environmental compliance equivalent to the main part.

The 74LVC1G86FW4-7 (Diodes Incorporated) is a parametric equivalent with identical electrical specifications and operating temperature range, differing only in the supplier device package designation. This part offers the highest inventory availability at 25,300 pieces.

The SN74LVC1G86YZPR (Texas Instruments) provides lower quiescent current consumption at 10 µA maximum, suitable for power-sensitive applications. The operating temperature range is limited to -40°C to 85°C, which may restrict use in extended temperature environments. The 5-DSBGA package represents a significant size reduction compared to DFN packages.

The 74LVC1G86GM,115 and 74LVC1G86GS,132 (Nexperia USA Inc.) offer the lowest quiescent current at 4 µA maximum, with full -40°C to 125°C operating temperature range. These parts utilize 6-XSON packages with different footprint dimensions (SOT886 and SOT1202 variants), providing space optimization options for compact designs.

Frequently Asked Questions (FAQ)

Q: Can the 74LVC1G86FW4-7 be used as a direct replacement for the 74LVC1G86FX4-7?

A: Yes. The 74LVC1G86FW4-7 is a parametric equivalent with identical electrical specifications, supply voltage range, output current capability, input logic thresholds, propagation delay, and operating temperature range. The difference lies in the supplier device package designation (X2-DFN1010-6 versus X2-DFN1409-6), but both maintain the 6-XFDFN case classification. PCB layout compatibility should be verified based on specific footprint requirements.

Q: What are the key differences between Diodes Incorporated and Nexperia variants?

A: Diodes Incorporated parts (74LVC1G86FX4-7 and 74LVC1G86FW4-7) specify a maximum quiescent current of 200 µA. Nexperia parts (74LVC1G86GM,115 and 74LVC1G86GS,132) specify 4 µA maximum quiescent current, representing a 50-fold reduction in standby power consumption. Both manufacturers provide full -40°C to 125°C operating temperature range. Package footprints differ between suppliers.

Q: Is the Texas Instruments SN74LVC1G86YZPR suitable for all applications?

A: The SN74LVC1G86YZPR maintains all core XOR logic specifications and offers 10 µA quiescent current. However, the operating temperature range is limited to -40°C to 85°C, compared to 125°C for other substitutes. Applications requiring operation above 85°C must use alternative parts. The 5-DSBGA package provides significant size reduction but requires compatible PCB footprint design.

Q: How do package differences affect substitution?

A: All substitutes maintain the 6-XFDFN case designation but utilize different supplier device packages. The 74LVC1G86FW4-7 uses X2-DFN1010-6, Nexperia parts use 6-XSON variants (SOT886 or SOT1202), and the Texas Instruments part uses 5-DSBGA. Physical footprint dimensions and pin configurations differ. PCB layout and assembly compatibility must be verified before substitution.

Q: Which substitute offers the best power efficiency?

A: The Nexperia parts (74LVC1G86GM,115 and 74LVC1G86GS,132) offer the lowest quiescent current at 4 µA maximum, providing optimal power efficiency for battery-powered or low-power applications. The choice between these two Nexperia variants depends on PCB space constraints and available footprint area.

Q: Are all substitutes RoHS and REACH compliant?

A: Yes. All identified substitutes are ROHS3 compliant and REACH unaffected, matching the compliance status of the main part 74LVC1G86FX4-7. All parts carry MSL 1 (Unlimited) moisture sensitivity rating.
