Substitute Part Grouping Explanation

Substitute parts for the 74HCT86N,652 are identified based on strict equivalence of the following critical parameters:

• Logic Type: XOR (Exclusive OR) with identical 4-channel, 2-input configuration
• Voltage Supply Range: 4.5V ~ 5.5V
• Current Specifications: Quiescent current 2 µA maximum; output drive 4mA high and low
• Input Logic Levels: Low 0.8V, High 2V
• Propagation Delay: 32ns @ 4.5V, 50pF maximum
• Package Type: 14-DIP through-hole form factor with 0.300" (7.62mm) pitch
• Base Series: 74HCT logic family

The CD74HCT86E from Harris Corporation meets all functional and electrical requirements for direct substitution, with identical logic configuration, voltage specifications, current ratings, and timing characteristics. Both parts share the same 14-DIP package footprint and base product number (74HCT86), ensuring mechanical and electrical compatibility in legacy circuit designs.

Parameter Comparison

Engineering Selection Recommendations

The CD74HCT86E qualifies as a direct functional equivalent to the 74HCT86N,652 based on identical electrical specifications, logic configuration, and package form factor. Both parts are classified as obsolete products within the 74HCT logic family.

Selection between these parts should consider the following compliance factors:

• The 74HCT86N,652 carries ROHS3 compliance certification, while the CD74HCT86E is RoHS non-compliant. For applications subject to RoHS regulatory requirements, the NXP part maintains compliance status.
• Both parts share EAR99 export classification and identical HTSUS commodity codes (8542.39.0001).
• The CD74HCT86E supports an extended operating temperature range (-55°C ~ 125°C) compared to the 74HCT86N,652 (-40°C ~ 125°C), providing broader thermal operation capability in applications requiring lower temperature performance.
• Moisture sensitivity classification (MSL 1 - Unlimited) is specified for the 74HCT86N,652; equivalent moisture handling data for the CD74HCT86E should be confirmed with the supplier.

For legacy system repairs and maintenance, either part provides electrical and mechanical compatibility. Compliance requirements and operating temperature specifications should guide final component selection.

Frequently Asked Questions (FAQ)

Q: Can the CD74HCT86E directly replace the 74HCT86N,652 in existing circuit designs?

A: Yes. Both parts share identical logic configuration (4-channel XOR), electrical specifications (voltage, current, timing), and 14-DIP package footprint. Direct pin-for-pin substitution is supported without circuit modification.

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

A: Substitution compatibility is determined by: logic type and channel configuration (4-channel, 2-input XOR), supply voltage range (4.5V ~ 5.5V), quiescent and output current ratings (2 µA, 4mA), input logic levels (0.8V low, 2V high), propagation delay (32ns @ 4.5V, 50pF), and package type (14-DIP through-hole). All these parameters are identical between the main part and substitute.

Q: Are there differences in RoHS compliance between these parts?

A: Yes. The 74HCT86N,652 is ROHS3 compliant, while the CD74HCT86E is RoHS non-compliant. Applications subject to RoHS regulatory requirements should use the NXP part.

Q: What is the operating temperature difference between these parts?

A: The 74HCT86N,652 operates from -40°C to 125°C, while the CD74HCT86E operates from -55°C to 125°C. The Harris part supports extended low-temperature operation.

Q: Are both parts available in the same package configuration?

A: Yes. Both the 74HCT86N,652 and CD74HCT86E are supplied in 14-DIP through-hole packages with 0.300" (7.62mm) pitch, ensuring identical PCB footprint compatibility.

Q: Why are both parts classified as obsolete?

A: Both the 74HCT86N,652 and CD74HCT86E are legacy logic components from the 74HCT family. Obsolete status reflects discontinuation by their respective manufacturers. Substitute identification ensures continued availability for system maintenance and repair applications.
