Engineering Selection Recommendations
Primary Substitutes (Active Status, Full Compliance):
MC74HC164ADR2G (onsemi) and MC74HC164BDR2G (onsemi) are the preferred alternatives. Both maintain active production status, ROHS3 compliance, unlimited moisture sensitivity rating, and identical operating temperature range (-55°C ~ 125°C). These components are available in high inventory quantities and provide direct functional equivalence.
74HC164S14-13 (Diodes Incorporated) and 74HC164D,653 (Nexperia USA Inc.) are secondary alternatives with active status and ROHS3 compliance. Operating temperature minimum is -40°C, which is acceptable for applications not requiring extended low-temperature operation below -40°C.
Conditional Substitutes:
CD74HC164MT (Texas Instruments) maintains identical specifications to the main part but carries Last Time Buy status, indicating limited future availability. This part is suitable only for immediate requirements with no long-term supply assurance.
SN74HC164D (Texas Instruments) is discontinued at DiGi Electronics and carries reduced operating temperature minimum (-40°C). Use only when supply constraints force selection and application temperature range permits.
Not Recommended:
MM74HC164MX and MM74HC164M (Fairchild Semiconductor) have restricted operating temperature maximum of 85°C, limiting suitability to applications with ambient temperatures below 85°C. RoHS and MSL compliance information is not specified.
NLV74HC164ADR2G (onsemi) carries obsolete status and should be avoided for new designs despite meeting electrical specifications.
Frequently Asked Questions (FAQ)
Q: Can I use a substitute part with a different operating temperature range?
A: Operating temperature range substitution is acceptable only when the application's actual operating conditions fall within the substitute part's specified range. For example, SN74HC164D with -40°C minimum is suitable for applications operating above -40°C. Parts with 85°C maximum (MM74HC164MX, MM74HC164M) are unsuitable for applications requiring operation above 85°C.
Q: Are all substitute parts pin-compatible with the CD74HC164M96?
A: Yes. All substitute parts use the identical 14-SOIC package with 0.154" width and 3.90mm dimensions. Pin configuration and functionality are identical across all listed substitutes.
Q: What is the difference between packaging formats (Tape & Reel, Tube, Cut Tape, Bulk)?
A: Packaging format affects handling, storage, and automated assembly compatibility but does not alter electrical or mechanical specifications. Tape & Reel (TR) is standard for high-volume surface mount assembly. Tube and Cut Tape formats are suitable for lower-volume or manual assembly. Bulk packaging is used for component distribution without tape or reel containment.
Q: Why is NLV74HC164ADR2G listed if it is obsolete?
A: Obsolete parts are included for reference in legacy system maintenance or repair scenarios where existing inventory may be available. For new designs, active-status alternatives are strongly preferred.
Q: Do all substitutes meet RoHS3 compliance?
A: Most listed substitutes are ROHS3 compliant. MM74HC164MX, MM74HC164M, and MC74HC164ADG do not specify RoHS status. Verify RoHS compliance with the manufacturer or distributor if regulatory compliance is required for your application.
Q: Can I mix different manufacturers' parts in the same design?
A: Yes. All substitute parts maintain identical electrical specifications, package dimensions, and pin configurations. Mixing manufacturers within a single design is electrically and mechanically valid. However, maintain consistent sourcing within production batches when possible to simplify supply chain management.
