Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74HC393D,652 is determined by strict equivalence across the following critical parameters:

• Logic Function: All substitutes must be dual 4-bit binary counters with negative edge triggering and asynchronous reset
• Package Compatibility: All substitutes must use 14-SOIC surface mount packaging (0.154", 3.90mm width)
• Electrical Specifications: Supply voltage range (2V ~ 6V) and operating temperature range must be met or exceeded
• Count Rate: Minimum count rate of 107 MHz is required for direct substitution; lower count rates indicate functional limitations
• Compliance: RoHS3 compliance and MSL 1 rating are maintained across all substitutes

Substitutes are grouped by manufacturer and packaging format (Tube, Tape & Reel, or Cut Tape). Packaging differences do not affect electrical or functional compatibility but may impact procurement and handling requirements.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute (Recommended for Direct Replacement)

74HC393D,653 (Nexperia USA Inc.) is the direct equivalent to 74HC393D,652. Both parts share identical electrical specifications, including 107 MHz count rate and -40°C to 125°C operating temperature range. The only difference is packaging format (Tape & Reel vs. Tube). This part maintains active product status and full RoHS3 compliance.

Secondary Substitutes (Functional Equivalents with Operational Constraints)

MC74HC393ADR2G and MC74HC393ADG (onsemi) are functionally equivalent with extended operating temperature range (-55°C to 125°C). Count rate is reduced to 50 MHz, which remains suitable for applications not requiring the full 107 MHz specification. Both parts are in active production status.

SN74HC393DR (Texas Instruments) is available in active status with Cut Tape & Digi-Reel packaging. Count rate is 36 MHz and operating temperature range is -40°C to 85°C, representing the most significant performance reduction among active alternatives.

Obsolete Alternatives (Not Recommended for New Designs)

NLV74HC393ADR2G (onsemi) is an automotive-grade variant (AEC-Q100 qualified) but is listed as obsolete. SN74HC393D and SN74HC393DT (Texas Instruments) are discontinued at DiGi Electronics and should not be selected for new production.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a lower count rate than the original 74HC393D,652?

A: Yes, if your application does not require the full 107 MHz count rate. Parts such as MC74HC393ADR2G (50 MHz) or SN74HC393DR (36 MHz) will function correctly in circuits designed for lower frequency operation. Verify your circuit's maximum clock frequency requirement before substitution.

Q: What is the difference between 74HC393D,652 and 74HC393D,653?

A: These parts are electrically identical. The difference is packaging format: 74HC393D,652 is supplied in Tube packaging, while 74HC393D,653 is supplied in Tape & Reel (TR) format. Both maintain the same 107 MHz count rate and -40°C to 125°C operating range. Selection depends on procurement and assembly requirements.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All listed substitute parts maintain RoHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, matching the original 74HC393D,652 specifications.

Q: Can I use onsemi parts as substitutes for the Nexperia original?

A: Yes. MC74HC393ADR2G and MC74HC393ADG are functionally equivalent and maintain the same 14-SOIC package. Both are in active production. Note that count rate is reduced to 50 MHz and operating temperature range is extended to -55°C to 125°C.

Q: Which substitute offers the best availability?

A: 74HC393D,653 (Nexperia) and SN74HC393DR (Texas Instruments) are listed as active products. MC74HC393ADR2G and MC74HC393ADG (onsemi) are also in active production. Availability should be confirmed with your component supplier.

Q: Is the automotive-grade NLV74HC393ADR2G suitable for my application?

A: NLV74HC393ADR2G is AEC-Q100 qualified but is currently listed as obsolete. It should not be selected for new designs unless automotive qualification is a specific requirement and availability can be confirmed through specialized suppliers.
