SN74HC86APW Equivalent & Substitute Parts

Part Overview

The SN74HC86APW is a Logic IC XOR (Exclusive OR) gate manufactured by Texas Instruments. This component is classified as a Last Time Buy product, indicating that it is no longer in active production. The SN74HC86APW performs 4-channel 2-input XOR logic operations and is designed for digital logic applications requiring exclusive OR functionality. Due to its Last Time Buy status, identifying equivalent substitute parts with compatible electrical and mechanical specifications is essential for design continuity and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SN74HC86APW is determined by the following critical parameters:

Logic Function: XOR (Exclusive OR) gate with 4 channels and 2 inputs per channel. Any substitute must maintain identical logic functionality.

Electrical Specifications: Supply voltage range (2V ~ 6V), quiescent current (2 µA maximum), output current ratings (5.2mA high and low), input logic levels, and propagation delay characteristics (15ns @ 6V, 50pF) must be equivalent or superior.

Compliance Requirements: RoHS3 compliance and MSL Level 1 rating are mandatory for substitution eligibility.

Series Designation: The 74HC series classification ensures compatibility within the standard logic IC family.

The substitute part SN74HC86APWR meets all these criteria while offering an Active product status and alternative packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The SN74HC86APW is designated as Last Time Buy, indicating discontinued production. The SN74HC86APWR substitute maintains Active product status with Texas Instruments, ensuring long-term availability and continued manufacturing support.

Compliance Alignment: Both parts maintain ROHS3 compliance and MSL Level 1 rating, satisfying regulatory and environmental requirements for equivalent substitution.

Inventory Availability: The substitute part SN74HC86APWR demonstrates significantly higher inventory levels (2807 Pcs versus 923 Pcs), providing improved procurement reliability and supply chain continuity.

Packaging Difference: The main part SN74HC86APW uses standard DIP packaging, while the substitute SN74HC86APWR employs 14-TSSOP surface mount packaging. This packaging transition requires PCB layout modification but maintains identical electrical functionality and compliance certifications.

Export Classification: Both parts share identical ECCN (EAR99) and HTSUS codes, confirming equivalent trade compliance status.

Frequently Asked Questions (FAQ)

Q: Can SN74HC86APWR directly replace SN74HC86APW in existing designs?

A: Electrical substitution is valid. Both parts share identical XOR logic functionality, supply voltage range (2V ~ 6V), and compliance certifications. However, SN74HC86APWR uses 14-TSSOP surface mount packaging while SN74HC86APW uses through-hole DIP packaging. PCB redesign is required for physical implementation.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by: (1) Logic function type (XOR with 4 channels, 2 inputs), (2) Supply voltage compatibility (2V ~ 6V), (3) RoHS3 compliance status, (4) MSL Level 1 rating, and (5) ECCN/HTSUS classification. All parameters must match or exceed the original specification.

Q: Why is the SN74HC86APW classified as Last Time Buy?

A: Last Time Buy designation indicates that Texas Instruments has discontinued production of this part number. Existing inventory is available for final orders, but no future manufacturing is planned. The SN74HC86APWR substitute provides continuity for new designs and future procurement.

Q: Are there any electrical performance differences between the two parts?

A: Both parts maintain identical XOR logic functionality and electrical specifications within the 74HC series standard. The substitute part SN74HC86APWR provides documented electrical parameters (quiescent current, output current, propagation delay, operating temperature range) that confirm compatibility with the original design requirements.

Q: What packaging considerations apply to the substitute part?

A: The SN74HC86APWR is supplied in 14-TSSOP (Thin Shrink Small Outline Package) surface mount configuration with Tape & Reel (TR) delivery format. This requires surface mount assembly capability and PCB layout modification compared to the through-hole DIP packaging of the original part.

Q: Are compliance certifications identical between both parts?

A: Yes. Both SN74HC86APW and SN74HC86APWR maintain ROHS3 compliance, MSL Level 1 rating, EAR99 export classification, and identical HTSUS code (8542.39.0001), confirming equivalent regulatory and environmental status.
