Substitute Part Grouping Explanation

Substitute parts for the CD74HC173M96G4 are classified based on the following critical parameters that determine functional and mechanical compatibility:

Primary Substitution Criteria:

• Base product number (74HC173 or 74HC175 series)
• Package type (16-SOIC surface mount)
• Voltage supply range (2V to 6V)
• Operating temperature range (-55°C to 125°C or -40°C to 125°C)
• Output configuration (tri-state or complementary)
• Trigger type (positive edge)
• Function (master reset)

Substitution Categories:

Direct Equivalent (Same Base Number - 74HC173): CD74HC173M96 and CD74HC173MT maintain identical electrical specifications and packaging, differing only in supplier packaging format (Cut Tape vs. standard tape).

Parametric Equivalent (Different Base Number - 74HC173 vs. 74HC175): MC74HC175ADG and MC74HC175ADR2G are from the 74HC175 series with complementary output configuration instead of tri-state non-inverted. These parts share the same 16-SOIC package and voltage supply range but operate at different clock frequencies and propagation delays.

Cross-Manufacturer Equivalent (NXP): 74HC173D,653 from NXP Semiconductors maintains the 74HC173 base number with identical package and function but exhibits improved performance specifications.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Identical Specifications): CD74HC173M96 is the primary recommended substitute. It maintains all electrical and mechanical specifications of the CD74HC173M96G4 while offering active product status and higher inventory availability. The difference between CD74HC173M96G4 and CD74HC173M96 is packaging format only (Tape & Reel vs. Cut Tape & Digi-Reel).

For Cross-Manufacturer Compatibility: 74HC173D,653 from NXP Semiconductors is suitable when cross-manufacturer sourcing is required. This part offers improved performance characteristics (95 MHz clock frequency, 30ns propagation delay, 4 µA quiescent current) while maintaining the same 16-SOIC package and tri-state non-inverted output configuration. Operating temperature range is -40°C to 125°C, which covers most industrial applications but excludes the extended low-temperature range of the original part.

For Alternative Output Configuration: MC74HC175ADG and MC74HC175ADR2G from onsemi are substitutes when complementary output configuration is acceptable. These parts operate at lower clock frequency (35 MHz) and lower propagation delay (22ns) with reduced output current (5.2mA). The 74HC175 base number indicates a different internal architecture suitable for applications requiring complementary outputs. Both parts maintain ROHS3 compliance and the 16-SOIC package.

Compliance Considerations: All recommended substitutes maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating. The CD74HC173M96 is the preferred choice for applications requiring strict compliance with the original part's specifications and extended temperature range.

Frequently Asked Questions (FAQ)

Q: Can CD74HC173M96 directly replace CD74HC173M96G4? A: Yes. CD74HC173M96 is a direct equivalent with identical electrical specifications. The only difference is packaging format (Cut Tape & Digi-Reel vs. Tape & Reel). Both parts are 16-SOIC surface mount devices with the same pin configuration and functional behavior.

Q: What is the difference between 74HC173 and 74HC175 series parts? A: The 74HC173 features tri-state non-inverted outputs, while the 74HC175 features complementary outputs. Both are D-Type flip-flops in the 74HC series with the same 16-SOIC package. The 74HC175 operates at lower clock frequency (35 MHz vs. 60 MHz) and has lower propagation delay (22ns vs. 34ns). Selection depends on whether your circuit requires tri-state or complementary output configuration.

Q: Is the NXP 74HC173D,653 compatible with the original part? A: Yes, for most applications. The NXP part maintains the same 74HC173 base number, tri-state non-inverted output, and 16-SOIC package. It offers improved performance (95 MHz clock frequency, 30ns propagation delay). The operating temperature range is -40°C to 125°C instead of -55°C to 125°C, which is suitable for commercial and industrial applications but not for extended low-temperature environments.

Q: What are the packaging differences between the substitute parts? A: All substitute parts use the same 16-SOIC (0.154", 3.90mm Width) surface mount package. Differences exist only in supplier packaging format: CD74HC173M96 is available in Cut Tape & Digi-Reel, CD74HC173MT in standard tape, 74HC173D,653 in bulk, MC74HC175ADG in tube, and MC74HC175ADR2G in Tape & Reel. The component itself and PCB footprint remain identical.

Q: Are all substitute parts ROHS3 compliant? A: CD74HC173M96, CD74HC173MT, MC74HC175ADG, and MC74HC175ADR2G are ROHS3 compliant. The NXP part 74HC173D,653 does not specify RoHS status in the provided data. Verify RoHS compliance with the manufacturer if this is a requirement for your application.

Q: What is the quiescent current difference between parts? A: CD74HC173M96G4, CD74HC173M96, and CD74HC173MT have 8 µA quiescent current. The NXP 74HC173D,653 and both onsemi MC74HC175 parts have 4 µA quiescent current. Lower quiescent current reduces power consumption in standby conditions, which may be beneficial for battery-powered applications.
