Engineering Selection Recommendations

Primary Upgrade Path: CD74HC175M96 (Texas Instruments) is the preferred upgrade substitute. It maintains identical electrical specifications to the 74HC175D,652, operates at active product status, carries ROHS3 compliance certification, and is available in Tape & Reel packaging for production environments.

Alternative Active Substitutes: MC74HC175ADG and MC74HC175ADR2G (onsemi) offer superior performance characteristics with reduced propagation delay (22 ns versus 30 ns) and lower quiescent current (4 µA versus 8 µA). Both parts maintain ROHS3 compliance and active product status. MC74HC175ADR2G is packaged in Tape & Reel format suitable for automated assembly.

Secondary Substitutes: MM74HC175MX (onsemi) and SN74HC175DR (Texas Instruments) provide active product status with ROHS3 compliance. Both maintain the 16-SOIC package footprint and core electrical specifications. SN74HC175DR offers the highest inventory availability.

Compliance Consideration: CD74HC175M (Harris Corporation) is RoHS non-compliant and should be avoided in applications requiring regulatory compliance certification.

Temperature Range Limitation: MM74HC175M, MM74HC175MX, SN74HC175D, SN74HC175DR, SN74HC175DT, and SN74HC175NSR operate within -40°C to 85°C temperature range, which is narrower than the original 74HC175D,652 specification (-40°C to 125°C). Applications requiring extended high-temperature operation above 85°C should utilize CD74HC175M96 or MC74HC175ADG/MC74HC175ADR2G.

Package Variant: SN74HC175NSR uses a 16-SOIC package with 0.209" width (5.30mm) versus the standard 0.154" width (3.90mm). PCB layout verification is required before substitution.

Frequently Asked Questions (FAQ)

Q: Can the 74HC175D,652 be directly replaced with any of the listed substitutes? A: All listed parts share the same base product number (74HC175), functional architecture, and core electrical specifications. Direct pin-for-pin replacement is possible for parts using the standard 16-SOIC (0.154", 3.90mm) package. SN74HC175NSR uses a wider package variant and requires PCB layout verification.

Q: What is the difference between "Upgrade" and "Similar" substitute classifications? A: Upgrade parts (CD74HC175M, CD74HC175M96) maintain identical electrical performance to the original part while offering improved product status or compliance certifications. Similar parts share the same functional architecture but may have variations in clock frequency, propagation delay, quiescent current, or operating temperature range that remain within acceptable substitution parameters.

Q: Which substitute offers the best performance improvement? A: MC74HC175ADG and MC74HC175ADR2G deliver superior performance with 22 ns propagation delay (versus 30 ns) and 4 µA quiescent current (versus 8 µA). Both maintain ROHS3 compliance and active product status.

Q: Are there supply chain considerations for these substitutes? A: CD74HC175M96, MC74HC175ADG, MC74HC175ADR2G, MM74HC175MX, and SN74HC175DR maintain active product status with confirmed inventory availability. CD74HC175M and SN74HC175D are obsolete or discontinued at major distributors. SN74HC175DT and SN74HC175D are discontinued at DiGi Electronics.

Q: Does operating temperature range affect substitution suitability? A: The original 74HC175D,652 operates from -40°C to 125°C. Substitutes with narrower temperature ranges (-40°C to 85°C) are suitable for applications not exceeding 85°C. For extended high-temperature operation, select CD74HC175M96, MC74HC175ADG, or MC74HC175ADR2G, which support -55°C to 125°C operation.

Q: What packaging formats are available for production environments? A: CD74HC175M96 and MC74HC175ADR2G are supplied in Tape & Reel format. MM74HC175MX and SN74HC175NSR are available in Tape & Reel. MC74HC175ADG and MM74HC175M are supplied in Tube packaging. Verify packaging requirements with your procurement process.

Q: Is RoHS compliance mandatory for my application? A: All substitutes except CD74HC175M carry ROHS3 compliance certification. CD74HC175M is RoHS non-compliant and should be avoided in regulated applications requiring environmental compliance documentation.
