Substitute Part Grouping Explanation

Substitution of the 74AC86SJ is determined by strict adherence to the following electrical and mechanical criteria:

Primary Substitution Criteria (Direct Equivalents):

• Logic Type: XOR (Exclusive OR), 4 channels, 2 inputs per channel
• Voltage Supply Range: 2V ~ 6V
• Current - Quiescent (Max): 2 µA
• Current - Output High/Low: 24mA / 24mA
• Input Logic Levels: Low 0.9V ~ 1.65V, High 2.1V ~ 3.85V
• Max Propagation Delay: 8.5ns @ 5V, 50pF
• Operating Temperature: -40°C ~ 85°C
• Mounting Type: Surface Mount
• Package / Case: 14-SOIC (0.209", 5.30mm Width)

Secondary Substitution Criteria (Functional Equivalents with Extended Parameters):

• Logic Type: XOR (Exclusive OR), 4 channels, 2 inputs per channel
• Voltage Supply Range: 1.5V ~ 5.5V (wider range, backward compatible)
• Current - Quiescent (Max): 4 µA (higher, acceptable for most applications)
• Current - Output High/Low: 24mA / 24mA
• Input Logic Levels: Low 0.3V ~ 1.65V, High 1.2V ~ 3.85V (wider range, backward compatible)
• Max Propagation Delay: 10.8ns @ 5V, 50pF (slower, acceptable for non-critical timing)
• Operating Temperature: -55°C ~ 125°C (extended range, backward compatible)
• Mounting Type: Surface Mount
• Package / Case: 14-SOIC (0.154", 3.90mm Width) (different physical dimensions)

Parts are grouped as direct equivalents when all primary criteria match exactly. Parts with extended parameter ranges are classified as functional equivalents suitable for applications not requiring the original specifications.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (Identical Electrical and Mechanical Specifications):

SN74AC86NSR (Texas Instruments) and SN74AC86DR (Texas Instruments) are direct electrical equivalents to the 74AC86SJ. Both maintain identical voltage supply ranges (2V ~ 6V), quiescent current (2 µA), propagation delay (8.5ns @ 5V, 50pF), and operating temperature range (-40°C ~ 85°C). SN74AC86NSR is currently active in production with Tape & Reel packaging, while SN74AC86DR is active with Cut Tape & Digi-Reel packaging. Both are ROHS3 compliant. Package dimensions match the original specification (14-SOIC, 0.209", 5.30mm Width).

SN74AC86D (Texas Instruments) is electrically equivalent but discontinued at DiGi Electronics, making it less suitable for new procurement despite matching all electrical parameters.

Functional Equivalents (Extended Parameter Ranges):

CD74AC86M (Harris Corporation) and CD74AC86M96 (Texas Instruments) are functional equivalents with extended electrical specifications. Both support wider voltage supply ranges (1.5V ~ 5.5V), higher quiescent current (4 µA), and extended operating temperature ranges (-55°C ~ 125°C). Propagation delay is slightly increased to 10.8ns @ 5V, 50pF. These parts are suitable for applications not requiring the original timing specifications. Physical package dimensions differ (14-SOIC, 0.154", 3.90mm Width), requiring PCB layout verification. CD74AC86M96 is currently active and ROHS3 compliant. CD74AC86M is obsolete and RoHS non-compliant.

Procurement Priority:

For new designs and ongoing procurement, SN74AC86NSR or SN74AC86DR are recommended as primary substitutes due to active product status, ROHS3 compliance, and identical electrical specifications. CD74AC86M96 is suitable as a secondary option when extended parameter ranges are acceptable and physical package dimensions can be accommodated.

Frequently Asked Questions (FAQ)

Q: Can SN74AC86NSR be used as a direct replacement for 74AC86SJ?

A: Yes. SN74AC86NSR is a direct electrical equivalent with identical voltage supply range (2V ~ 6V), quiescent current (2 µA), propagation delay (8.5ns @ 5V, 50pF), and operating temperature range (-40°C ~ 85°C). Package dimensions are identical (14-SOIC, 0.209", 5.30mm Width). No circuit modifications are required.

Q: What is the difference between SN74AC86NSR and SN74AC86DR?

A: Both are direct electrical equivalents with identical specifications. The primary difference is packaging format: SN74AC86NSR is supplied in Tape & Reel (TR), while SN74AC86DR is supplied in Cut Tape (CT) & Digi-Reel format. Selection depends on procurement and assembly requirements.

Q: Can CD74AC86M96 be used instead of 74AC86SJ?

A: CD74AC86M96 is a functional equivalent with extended electrical specifications. It supports a wider voltage supply range (1.5V ~ 5.5V) and extended operating temperature range (-55°C ~ 125°C), making it backward compatible with the original specification. However, propagation delay is increased to 10.8ns @ 5V, 50pF, and physical package dimensions differ (14-SOIC, 0.154", 3.90mm Width). Use only if timing requirements are not critical and PCB layout can accommodate the different package dimensions.

Q: Why do CD74AC86M and CD74AC86M96 have different package dimensions?

A: Both use 14-SOIC packaging but with different body widths. CD74AC86M uses 0.154" (3.90mm) width, while 74AC86SJ uses 0.209" (5.30mm) width. This affects PCB footprint and requires layout verification before substitution.

Q: Is CD74AC86M suitable for new designs?

A: No. CD74AC86M is obsolete and RoHS non-compliant. For new designs, use SN74AC86NSR, SN74AC86DR, or CD74AC86M96, all of which are active and ROHS3 compliant.

Q: What is the significance of the 74AC86 base product number?

A: The 74AC86 base product number identifies the core logic function (4-channel, 2-input XOR gate) across all manufacturers and packaging variants. Substitutes sharing this base number maintain functional equivalence, though specific electrical parameters and package formats may vary by manufacturer and part number suffix.

Q: Are all substitute parts MSL 1 (Unlimited)?

A: Most substitute parts are MSL 1 (Unlimited), including SN74AC86NSR, CD74AC86M96, SN74AC86D, and SN74AC86DR. CD74AC86M does not specify MSL rating. Verify moisture sensitivity requirements for your specific assembly process.
