SN74F86DRG4 Equivalent & Substitute Parts

Part Overview

The SN74F86DRG4 is a 4-channel XOR (Exclusive OR) logic IC manufactured by Texas Instruments in a 14-SOIC surface mount package. This component is discontinued at DiGi Electronics, making identification of equivalent substitute parts essential for ongoing design support and procurement.

The XOR logic function processes two inputs per channel across four independent circuits, operating within a 4.5V to 5.5V supply voltage range with a maximum propagation delay of 7ns at 5V with 50pF load. The part is ROHS3 compliant and carries MSL Level 1 (Unlimited) moisture sensitivity rating.

Substitute Part Grouping Explanation

Substitution of the SN74F86DRG4 is determined by strict equivalence across the following critical parameters:

Logic Type: XOR (Exclusive OR) with 4 channels and 2 inputs per channel
Electrical Specifications: 4.5V ~ 5.5V supply voltage, 1mA/20mA output current, 0.8V/2V input logic levels, 7ns maximum propagation delay
Package: 14-SOIC surface mount form factor with identical 0.154" (3.90mm) width
Compliance: ROHS3 compliance and MSL Level 1 rating

The SN74F86DR qualifies as a parametric equivalent based on identical electrical and functional specifications. The primary distinction is packaging format: the SN74F86DRG4 is supplied in tube packaging, while the SN74F86DR is supplied in Tape & Reel (TR) format.

Engineering Selection Recommendations

The SN74F86DR is a direct parametric equivalent to the SN74F86DRG4 with identical electrical performance and package specifications. Selection between these parts should be based on the following factors:

Product Status: The SN74F86DRG4 is discontinued at DiGi Electronics, while the SN74F86DR maintains active status with 3800 units in stock. For new designs or ongoing procurement, the SN74F86DR is the preferred selection.

Compliance & Certifications: Both parts carry identical ROHS3 compliance and MSL Level 1 ratings, ensuring equivalent environmental and regulatory suitability.

Packaging Format: The SN74F86DRG4 is supplied in tube packaging, while the SN74F86DR is supplied in Tape & Reel (TR) format. Tape & Reel packaging is standard for automated assembly processes and high-volume production. Tube packaging may be preferred for manual assembly or lower-volume applications. Verify your assembly process requirements before final selection.

Frequently Asked Questions (FAQ)

Q: Can the SN74F86DR be used as a direct replacement for the SN74F86DRG4?

A: Yes. The SN74F86DR is electrically and functionally identical to the SN74F86DRG4 across all specified parameters, including logic type, supply voltage, output current, propagation delay, and operating temperature range. Both use the 14-SOIC surface mount package with identical dimensions.

Q: What is the difference between the SN74F86DRG4 and SN74F86DR?

A: The primary difference is packaging format. The SN74F86DRG4 is supplied in tube packaging, while the SN74F86DR is supplied in Tape & Reel (TR) format. All electrical and functional specifications are identical.

Q: Why is the SN74F86DRG4 discontinued?

A: The SN74F86DRG4 is discontinued at DiGi Electronics. The SN74F86DR remains in active production and is the recommended alternative for new procurement.

Q: Are there any compatibility concerns when switching from SN74F86DRG4 to SN74F86DR?

A: No compatibility concerns exist at the electrical or functional level. Both parts are pin-compatible and operate identically within the specified parameters. Verify that your assembly process can accommodate Tape & Reel packaging if switching from tube format.

Q: What does the "G4" suffix in SN74F86DRG4 indicate?

A: The "G4" suffix indicates the tube packaging format. The "DR" in SN74F86DR indicates Tape & Reel packaging. Both are standard packaging designations for the same base product (74F86).

Q: Are both parts ROHS3 compliant?

A: Yes. Both the SN74F86DRG4 and SN74F86DR are ROHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating.
