Substitute Part Grouping Explanation
Substitution eligibility for the 74HC86D,652 is determined by the following critical parameters:
- Logic function: XOR (Exclusive OR) with 4 channels and 2 inputs per channel
- Package type: 14-SOIC surface mount form factor
- Voltage supply range: 2V to 6V minimum compatibility
- Input/output logic levels: 0.5V to 1.8V (low), 1.5V to 4.2V (high)
- Propagation delay: Maximum 20 ns @ 6V, 50pF load
- Operating temperature: Minimum -40°C to 125°C range
- RoHS3 compliance and MSL 1 rating
Substitute parts are grouped into three categories: direct equivalents (identical packaging and specifications), upgraded variants (extended temperature range or improved performance), and alternative manufacturers (same base functionality with minor parameter variations).

Engineering Selection Recommendations
Primary Recommendation: 74HC86D,653
The 74HC86D,653 from Nexperia USA Inc. is the direct functional equivalent with identical electrical specifications and 14-SOIC packaging. This part maintains active product status and is available in Tape & Reel packaging, providing superior availability compared to the obsolete 74HC86D,652.
Secondary Recommendation: CD74HC86M96
The CD74HC86M96 from Texas Instruments offers active product status with extended operating temperature range (-55°C to 125°C versus -40°C to 125°C). This variant is suitable for applications requiring broader temperature coverage and is available in Cut Tape & Digi-Reel packaging.
Alternative Recommendation: MC74HC86ADG
The MC74HC86ADG from onsemi provides improved performance characteristics with reduced quiescent current (1 µA versus 2 µA) and faster propagation delay (17 ns versus 20 ns). This part maintains active status and RoHS3 compliance with extended temperature range (-55°C to 125°C).
Temperature-Limited Applications: MM74HC86M or MM74HC86MX
For applications with operating temperature limits of -40°C to 85°C, the Fairchild Semiconductor MM74HC86M and MM74HC86MX variants are available with active product status. The MM74HC86MX offers bulk packaging with high inventory availability.
All recommended substitutes maintain 14-SOIC package compatibility, RoHS3 compliance, and MSL 1 rating where specified.
Frequently Asked Questions (FAQ)
Q: Can I use 74HC86D,653 as a direct replacement for 74HC86D,652?
A: Yes. Both parts share identical electrical specifications, logic function, and 14-SOIC packaging. The primary difference is packaging format (Tape & Reel versus Tube) and product status (Active versus Obsolete). Electrical performance and pinout are equivalent.
Q: What is the difference between the Texas Instruments CD74HC86M and CD74HC86M96 variants?
A: Both parts are functionally identical with 2 µA quiescent current and 20 ns propagation delay. The CD74HC86M96 is available in Cut Tape & Digi-Reel packaging with active product status, while CD74HC86M is in Tube packaging with obsolete status. The CD74HC86M96 is the preferred choice for new designs.
Q: Why do some substitutes show faster propagation delay (17 ns) than the original part (20 ns)?
A: Faster propagation delay indicates improved performance and is a compatible substitution parameter. Parts with 17 ns delay (MC74HC86ADG, MC74HC86ADR2G, SN74HC86D) will function correctly in applications designed for 20 ns maximum delay. This represents a performance upgrade, not a compatibility issue.
Q: Are there temperature range limitations I should consider?
A: Yes. The original 74HC86D,652 operates from -40°C to 125°C. Substitutes from Fairchild Semiconductor (MM74HC86M, MM74HC86MX) are limited to -40°C to 85°C and are unsuitable for applications requiring the full -40°C to 125°C range. Texas Instruments and onsemi variants extend to -55°C to 125°C, providing broader coverage.
Q: Is the NLV74HC86ADR2G suitable as a substitute?
A: The NLV74HC86ADR2G is automotive-grade (AEC-Q100 qualified) with obsolete product status. While electrically compatible, its 26 ns propagation delay exceeds the original 20 ns specification. Use only if automotive qualification is required and timing margin permits the additional delay.
Q: What packaging options are available for substitutes?
A: Substitutes are available in Tube, Tape & Reel, Cut Tape & Digi-Reel, and Bulk packaging formats. All maintain the 14-SOIC (0.154", 3.90mm Width) form factor. Select packaging based on procurement volume and assembly process requirements.
Q: Do all substitutes maintain RoHS3 compliance?
A: RoHS3 compliance is confirmed for Nexperia, Texas Instruments, and onsemi parts. Fairchild Semiconductor variants (MM74HC86M, MM74HC86MX, MC74HC86ADR2G) do not specify RoHS3 status in available documentation. Verify compliance requirements for your application before selection.
