Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD74HC86EG4 is determined by strict equivalence across the following parameters:

• Logic Function: XOR gate with 4 channels and 2 inputs per channel
• Electrical Specifications: Supply voltage range (2V ~ 6V), quiescent current (2 µA max), output current (5.2mA), and propagation delay (20ns @ 6V, 50pF)
• Thermal Range: Operating temperature from -55°C to 125°C
• Package Compatibility: 14-DIP through-hole mounting with 0.300" (7.62mm) pitch
• Base Product Series: 74HC86 logic family

The CD74HC86E from Harris Corporation meets all electrical and mechanical parameters required for direct substitution. Both parts share identical functional specifications, electrical characteristics, and physical packaging, enabling pin-for-pin replacement in circuit designs.

Parameter Comparison

Engineering Selection Recommendations

CD74HC86E (Harris Corporation) is the direct substitute for CD74HC86EG4. Both components are classified as obsolete products. The CD74HC86EG4 carries ROHS3 compliance and unlimited moisture sensitivity level (MSL 1), while the CD74HC86E is RoHS non-compliant. For applications requiring RoHS compliance, alternative sourcing strategies or design modifications may be necessary. The CD74HC86E is available in tube packaging with higher inventory levels (2,868 pieces) compared to the original part, supporting production continuity.

Frequently Asked Questions (FAQ)

Q: Can CD74HC86E replace CD74HC86EG4 in existing designs? A: Yes. Both parts are pin-for-pin compatible with identical electrical specifications, supply voltage range, output current ratings, propagation delay, and operating temperature range. The 14-DIP through-hole package is identical.

Q: What is the difference in RoHS compliance between these parts? A: CD74HC86EG4 is ROHS3 compliant, while CD74HC86E is RoHS non-compliant. For applications subject to RoHS regulations, this distinction must be evaluated against compliance requirements.

Q: Are there packaging differences between the two parts? A: CD74HC86EG4 packaging type is not specified in available data. CD74HC86E is supplied in tube packaging. Both use the same 14-DIP (0.300", 7.62mm) physical package for through-hole mounting.

Q: What is the moisture sensitivity level (MSL) for CD74HC86E? A: MSL data for CD74HC86E is not provided in the available specifications. CD74HC86EG4 has MSL 1 (unlimited), indicating no moisture sensitivity restrictions.

Q: Are both parts still in production? A: No. Both CD74HC86EG4 and CD74HC86E are obsolete or discontinued products. Inventory availability is limited to existing stock from authorized distributors.
