SN74F86D Equivalent & Substitute Parts

Part Overview

The SN74F86D is a 4-channel XOR (Exclusive OR) logic IC manufactured by Texas Instruments in a 14-SOIC surface mount package. This component is classified as Last Time Buy, indicating discontinued production with limited availability. The SN74F86D remains in active use in legacy systems and applications requiring XOR gate functionality. Identifying equivalent substitute parts is necessary due to inventory constraints and the product's end-of-life status.

Substitute Part Grouping Explanation

Substitution of the SN74F86D is determined by strict equivalence across the following critical parameters:

• Logic function: XOR gate with 4 channels and 2 inputs per channel
• Electrical specifications: Supply voltage range 4.5V ~ 5.5V, output current ratings, input logic levels, and propagation delay
• Package format: 14-SOIC surface mount package with identical physical dimensions
• Compliance certifications: ROHS3 compliance and MSL rating

The SN74F86DR qualifies as a direct substitute based on identical electrical and mechanical specifications. The primary distinction is packaging format: the SN74F86D is supplied in Tube packaging (Last Time Buy status), while the SN74F86DR is supplied in Tape & Reel format with Active product status.

Parameter Comparison

Engineering Selection Recommendations

The SN74F86DR is the direct equivalent substitute for the SN74F86D. Both parts are manufactured by Texas Instruments with identical electrical performance, logic function, and package specifications. The SN74F86DR is preferred for new designs and ongoing production due to its Active product status and continuous availability in Tape & Reel packaging format. The SN74F86D remains suitable for legacy system maintenance where existing inventory is available, though procurement should transition to the SN74F86DR to ensure long-term supply chain continuity. Both parts maintain ROHS3 compliance and MSL Level 1 certification, meeting environmental and moisture sensitivity requirements.

Frequently Asked Questions (FAQ)

Q: Can the SN74F86DR directly replace the SN74F86D in existing designs?

A: Yes. The SN74F86DR is electrically and mechanically identical to the SN74F86D. Both parts feature the same 14-SOIC package, supply voltage range, output current ratings, propagation delay, and operating temperature specifications. No circuit modifications are required.

Q: What is the difference between the SN74F86D and SN74F86DR?

A: The primary difference is packaging format and product status. The SN74F86D is supplied in Tube packaging and is Last Time Buy. The SN74F86DR is supplied in Tape & Reel format and maintains Active product status with ongoing availability.

Q: Are there any compatibility concerns when switching from SN74F86D to SN74F86DR?

A: No compatibility concerns exist. Both parts use the identical 14-SOIC surface mount package with matching pin configuration, electrical characteristics, and performance specifications. PCB layout and assembly processes remain unchanged.

Q: What does Last Time Buy status mean for the SN74F86D?

A: Last Time Buy indicates that Texas Instruments has discontinued production of the SN74F86D. Existing inventory is available for purchase, but no new production runs are planned. The SN74F86DR should be specified for new designs to ensure continued availability.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the SN74F86D and SN74F86DR are ROHS3 compliant and carry MSL Level 1 (Unlimited) moisture sensitivity rating. Both parts are REACH Unaffected and classified under ECCN EAR99.
