Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74HC86DB,112 is determined by the following critical parameters:

• Logic Function: All substitutes must implement 4-channel 2-input XOR logic
• Electrical Specifications: Supply voltage (2V ~ 6V), quiescent current, output current, input logic levels, and propagation delay must remain within compatible ranges
• Package Compatibility: The original 14-SSOP package can be substituted with 14-TSSOP variants, which share identical pinout and electrical characteristics but differ in physical dimensions
• Operating Temperature Range: Substitutes must support the required temperature range; parts rated to -40°C ~ 85°C are acceptable for applications not requiring the full -40°C ~ 125°C range
• Compliance & Status: Active product status is preferred; discontinued parts may have limited availability

Substitute parts are grouped by manufacturer (Nexperia, Texas Instruments, Fairchild Semiconductor) and packaging format (Tape & Reel, Tube, Cut Tape). All listed substitutes maintain functional and electrical equivalence to the main part.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute (Direct Replacement): 74HC86PW,118 (Nexperia USA Inc.) is the most direct substitute, offering identical electrical specifications and full temperature range support (-40°C ~ 125°C) as the original 74HC86DB,112. The transition from 14-SSOP to 14-TSSOP packaging requires PCB layout verification due to different physical dimensions, though pinout remains compatible.

Active Commercial Alternative: SN74HC86PWR (Texas Instruments) provides active product status with improved propagation delay (17ns vs. 20ns) and maintains full RoHS3 compliance. Operating temperature is limited to -40°C ~ 85°C, suitable for non-extended-range applications.

Automotive-Grade Options: SN74HC86QPWRG4Q1 and SN74HC86QPWRQ1 (Texas Instruments) are AEC-Q100 qualified automotive-grade parts with full temperature range support (-40°C ~ 125°C). These parts exhibit higher quiescent current (40 µA) and propagation delay (25ns) compared to the original specification but maintain functional equivalence for automotive applications.

Fairchild Alternative: MM74HC86MTCX (Fairchild Semiconductor) offers active status with standard specifications but limited operating temperature range (-40°C ~ 85°C).

Avoid SN74HC86PW (Texas Instruments), which is discontinued at DiGi Electronics despite remaining in inventory.

Frequently Asked Questions (FAQ)

Q: Can I directly replace 74HC86DB,112 with 74HC86PW,118 on my PCB?

A: Electrical substitution is direct; both parts are functionally equivalent with identical logic specifications and temperature range. However, physical substitution requires PCB layout review. The 14-SSOP package (0.209" width) differs from 14-TSSOP (0.173" width), necessitating footprint verification before assembly.

Q: What is the difference between the Nexperia and Texas Instruments versions?

A: All 74HC86 variants from different manufacturers implement the same XOR logic function and share compatible electrical specifications. Differences exist in propagation delay (17ns to 25ns), quiescent current (2µA to 40µA), and temperature range support. Texas Instruments offers automotive-grade options with AEC-Q100 qualification; Nexperia provides standard commercial-grade parts.

Q: Can I use SN74HC86QPWRG4Q1 in a non-automotive application?

A: Yes. Automotive-grade parts exceed commercial-grade requirements and are fully compatible with standard applications. The AEC-Q100 qualification indicates enhanced reliability testing and process control, making these parts suitable for any 74HC86 application. Higher quiescent current (40 µA vs. 2 µA) and propagation delay (25ns vs. 20ns) must be evaluated against circuit timing requirements.

Q: Why do some substitutes have different operating temperature ranges?

A: The original 74HC86DB,112 supports -40°C ~ 125°C. Substitutes rated to -40°C ~ 85°C are suitable for applications not requiring extended high-temperature operation. If your design requires the full -40°C ~ 125°C range, select 74HC86PW,118, SN74HC86QPWRG4Q1, or SN74HC86QPWRQ1.

Q: Is the 74HC86 series still in production?

A: The original 74HC86DB,112 is obsolete. However, multiple active substitutes exist from Nexperia, Texas Instruments, and Fairchild Semiconductor, ensuring continued availability and design support for new projects.

Q: What does RoHS3 compliance mean for my application?

A: RoHS3 compliance indicates the part meets Restriction of Hazardous Substances Directive requirements, restricting lead and other hazardous materials. All listed substitutes maintain RoHS3 compliance, suitable for commercial and industrial applications subject to environmental regulations.
