Substitute Part Grouping Explanation

Substitution for the SN74AHCT86RGYRG4 is determined by strict equivalence across the following parameters:

• Logic Type: XOR (Exclusive OR)
• Number of Circuits: 4 channels
• Number of Inputs: 2 inputs per channel
• Voltage - Supply: 4.5V ~ 5.5V
• Current - Quiescent (Max): 2 µA
• Current - Output High, Low: 8mA, 8mA
• Input Logic Level - Low: 0.8V
• Input Logic Level - High: 2V
• Max Propagation Delay @ V, Max CL: 8.8ns @ 5V, 50pF
• Operating Temperature: -40°C ~ 85°C
• Package / Case: 14-VFQFN Exposed Pad
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 2 (1 Year)

The primary difference between the main part and its substitute is packaging format and product status. The SN74AHCT86RGYRG4 is supplied in tube packaging and is discontinued, while the substitute is available in Tape & Reel format and maintains active product status.

Parameter Comparison

Engineering Selection Recommendations

The SN74AHCT86RGYR is a direct parametric equivalent to the SN74AHCT86RGYRG4. Both parts are manufactured by Texas Instruments, share identical electrical specifications, and are housed in the same 14-VFQFN package. Both maintain ROHS3 compliance and identical moisture sensitivity ratings.

Selection between these parts should be based on:

• Product Status: The SN74AHCT86RGYR maintains active product status, while the SN74AHCT86RGYRG4 is discontinued.
• Packaging Format: The SN74AHCT86RGYR is supplied in Tape & Reel format, suitable for automated assembly. The SN74AHCT86RGYRG4 is supplied in tube packaging.
• Inventory Availability: The SN74AHCT86RGYR has significantly higher inventory availability (3826 Pcs vs. 847 Pcs).

For new designs and ongoing production, the SN74AHCT86RGYR is the recommended selection due to active product status and superior availability.

Frequently Asked Questions (FAQ)

Q: Can the SN74AHCT86RGYR directly replace the SN74AHCT86RGYRG4 in existing designs?

A: Yes. Both parts are parametrically identical across all electrical and mechanical specifications. The 14-VFQFN package dimensions and pinout are identical, enabling direct substitution on PCBs designed for either part number.

Q: What is the difference between the tube and Tape & Reel packaging formats?

A: Tube packaging is used for manual handling and small-quantity applications. Tape & Reel packaging is designed for automated pick-and-place assembly equipment. The components themselves are identical; only the delivery format differs.

Q: Are both parts RoHS compliant?

A: Yes. Both the SN74AHCT86RGYRG4 and SN74AHCT86RGYR are ROHS3 compliant and carry identical moisture sensitivity ratings of MSL 2 (1 Year).

Q: Why is the SN74AHCT86RGYRG4 discontinued?

A: Product discontinuation is determined by the manufacturer and distributor. The SN74AHCT86RGYR remains in active production and is the recommended alternative for new orders.

Q: Do these parts require different handling procedures?

A: No. Both parts share identical moisture sensitivity levels (MSL 2, 1 Year) and require the same storage and handling protocols.
