Engineering Selection Recommendations

Preferred Substitutes (Active Status, ROHS3 Compliant):

74HC164D,653 (Nexperia USA Inc.) — Direct variant from the same manufacturer with identical electrical specifications and improved availability. ROHS3 compliant with MSL 1 rating.
74HC164S14-13 (Diodes Incorporated) — Active production status with full ROHS3 compliance and MSL 1 rating. Maintains original temperature range (-40°C to 125°C).
CD74HC164M96 (Texas Instruments) — Active production with extended temperature range (-55°C to 125°C), ROHS3 compliant, and MSL 1 rating. Suitable for applications requiring broader thermal performance.
MC74HC164ADR2G (onsemi) — Active production with extended temperature range (-55°C to 125°C), ROHS3 compliant, and MSL 1 rating. High inventory availability (125,200 pcs).

Secondary Substitutes (Active Status, Compliance Verification Required):

Frequently Asked Questions (FAQ)

Q: Can I use 74HC164D,653 as a direct replacement for 74HC164D,652?

A: Yes. Both parts are manufactured by Nexperia USA Inc. and share identical electrical specifications, voltage supply range (2V to 6V), operating temperature range (-40°C to 125°C), and 14-SOIC package. The primary difference is packaging format (Cut Tape & Digi-Reel vs. standard packaging) and product status (Active vs. Obsolete). The 74HC164D,653 is the recommended upgrade path.

Q: What is the difference between parts with -40°C to 125°C and -55°C to 125°C temperature ranges?

A: The extended temperature range (-55°C to 125°C) encompasses the original specification (-40°C to 125°C) and provides additional margin for applications operating in extreme cold environments. Parts with extended ranges are fully compatible and can be used as direct substitutes without functional impact.

Q: Are all substitute parts in the same 14-SOIC package?

A: Yes. All listed substitute parts use the 14-SOIC (0.154", 3.90mm Width) surface mount package. They are mechanically and electrically compatible for PCB assembly without layout modifications.

Q: What does ROHS3 Compliant mean, and why does it matter?

A: ROHS3 Compliance indicates the part meets Restriction of Hazardous Substances Directive requirements, restricting lead, cadmium, mercury, and other hazardous materials. For applications subject to environmental regulations or customer requirements, ROHS3 compliant parts (74HC164D,653, 74HC164S14-13, CD74HC164M96, MC74HC164ADR2G, NLV74HC164ADR2G) are mandatory. Non-compliant parts (CD74HC164M) may only be used in legacy or unrestricted applications.

Q: What is Moisture Sensitivity Level (MSL), and why is MSL 1 important?

A: MSL 1 (Unlimited) indicates the component has no moisture sensitivity restrictions and requires no special handling, storage, or baking procedures before soldering. Parts with MSL 1 rating simplify manufacturing logistics and reduce assembly risk. Most recommended substitutes carry MSL 1 certification.

Q: Can I use parts with different packaging formats (Tape & Reel, Tube, Bulk)?

A: Yes. Tape & Reel, Tube, and Bulk packaging formats contain electrically identical components. The packaging format affects only procurement, storage, and assembly handling. Select based on your manufacturing process and inventory management requirements.

Q: Why is the 74HC164D,652 marked as Obsolete?

A: Obsolete status indicates the manufacturer has discontinued production and no longer accepts new orders. Existing inventory may be available through authorized distributors, but long-term supply cannot be guaranteed. Transitioning to active alternatives (74HC164D,653, 74HC164S14-13, CD74HC164M96, MC74HC164ADR2G) ensures design continuity and supply chain stability.
