Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74HC597D,652 is determined by the following critical parameters:

• Base Product Number: All substitutes must be 74HC597 series components
• Logic Type & Function: Shift register with parallel-to-serial or parallel/serial-to-serial capability
• Bit Configuration: 1 element, 8 bits per element
• Output Type: Push-pull output
• Supply Voltage: 2V ~ 6V operating range
• Package Type: 16-SOIC surface mount (with allowance for minor package width variations: 0.154" or 0.209")
• Mounting Type: Surface mount only

Substitute parts are grouped by product status and compliance certification. Direct substitutes maintain identical electrical and mechanical specifications. Upgrade substitutes offer extended temperature ranges or improved availability while maintaining core functionality.

Parameter Comparison

Engineering Selection Recommendations

Recommended Primary Substitutes (Active Status, ROHS3 Compliant)

MC74HC597ADR2G (onsemi) is the preferred direct substitute, offering active product status, ROHS3 compliance, extended operating temperature range (-55°C ~ 125°C), and highest inventory availability (32,620 units). This part maintains identical package specifications and electrical characteristics.

CD74HC597M96 (Texas Instruments) provides an alternative with active status and substantial inventory (74,275 units), suitable for high-volume applications requiring extended temperature performance.

Secondary Substitutes (Active Status, Package Variation)

CD74HC597NSR (Texas Instruments) is electrically equivalent but features a wider 16-SOIC package (0.209" width versus 0.154"). This part is suitable only if PCB layout accommodates the increased package width.

MC74HC597ADG (onsemi) offers active status and ROHS3 compliance in tube packaging, with lower inventory levels (1,769 units).

Obsolete or Limited-Life Alternatives

CD74HC597M (Harris Corporation) is obsolete and RoHS non-compliant. Use only when no other alternatives are available.

CD74HC597MT (Texas Instruments) carries Last Time Buy status, indicating discontinued production. Inventory is limited (6,990 units).

Frequently Asked Questions (FAQ)

Q: Can MC74HC597ADR2G directly replace 74HC597D,652 without PCB modifications?

A: Yes. MC74HC597ADR2G maintains identical electrical specifications, supply voltage range (2V ~ 6V), package type (16-SOIC 0.154" width), and pin configuration. No PCB layout changes are required.

Q: What is the difference between CD74HC597NSR and other substitutes?

A: CD74HC597NSR uses a wider 16-SOIC package (0.209" width) compared to the standard 0.154" width. Electrical function is identical, but physical footprint differs. Verify PCB layout compatibility before selection.

Q: Why is CD74HC597M not recommended despite availability?

A: CD74HC597M is RoHS non-compliant and carries obsolete status. It does not meet current environmental and regulatory requirements for new designs or production environments with RoHS mandates.

Q: What is the temperature operating range difference between the main part and substitutes?

A: The 74HC597D,652 operates from -40°C to 125°C. Most substitutes extend the lower limit to -55°C, providing wider temperature coverage. This is a functional improvement with no compatibility concerns.

Q: Are all substitutes available in the same packaging formats?

A: No. Substitutes are available in Tape & Reel (TR), Cut Tape (CT) & Digi-Reel®, and Tube formats. Select based on production volume and assembly equipment compatibility.

Q: Which substitute offers the best long-term availability?

A: CD74HC597M96 (Texas Instruments) with active status and highest inventory (74,275 units) provides the strongest long-term availability. MC74HC597ADR2G (onsemi) is the secondary choice with 32,620 units in stock.
