Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74HC595DB,112 is determined by the following critical parameters:

• Logic Function: All substitutes must perform 8-bit shift register operation with serial-to-parallel conversion
• Electrical Specifications: Supply voltage range (2V ~ 6V) and tri-state output configuration must be maintained
• Package Compatibility: Substitutes are grouped by package type (16-SSOP or 16-TSSOP), which determines PCB footprint compatibility
• Manufacturer: Multiple manufacturers produce 74HC595 variants with identical electrical function
• Product Status: Active parts are preferred over obsolete or discontinued variants for long-term availability

Substitutes are classified into two package families: 16-SSOP (0.209" width) and 16-TSSOP (0.173" width). Parts within the same package family are pin-compatible and electrically interchangeable. Cross-package substitution requires PCB redesign.

Parameter Comparison

Engineering Selection Recommendations

For 16-SSOP Package (Direct Footprint Match)

CD74HC595SM96 (Texas Instruments) is the primary substitute for the obsolete 74HC595DB,112. Both parts use the 16-SSOP package with identical 0.209" width. The CD74HC595SM96 offers extended operating temperature range (-55°C ~ 125°C) compared to the original part (-40°C ~ 125°C), providing superior performance in extreme temperature environments. Product status is active with established supply chain availability.

SN74HC595DBR (Texas Instruments) provides an alternative 16-SSOP option with active product status. Operating temperature range is -40°C ~ 85°C, which is narrower than the original specification but suitable for standard industrial applications.

For 16-TSSOP Package (PCB Redesign Required)

74HC595PW,118 (Nexperia USA Inc.) is an active substitute in the 16-TSSOP package. This part maintains the original manufacturer (Nexperia) and matches all electrical specifications. The narrower package (0.173" width) requires PCB layout modification but offers improved space efficiency.

SN74HC595PWR (Texas Instruments) is an active 16-TSSOP option with high inventory availability (14,700 pcs). This part is recommended for new designs requiring the compact TSSOP footprint.

MM74HC595MTCX (onsemi) provides a third-source alternative in 16-TSSOP packaging with active status and substantial inventory (31,285 pcs).

All recommended substitutes maintain ROHS3 compliance and MSL Level 1 rating, ensuring compatibility with standard manufacturing processes.

Frequently Asked Questions (FAQ)

Q: Can I use a 16-TSSOP package part as a direct replacement for the 16-SSOP 74HC595DB,112?

A: No. While both packages contain identical electrical function, the physical footprints differ (0.209" width for SSOP versus 0.173" width for TSSOP). Direct substitution requires PCB redesign. For drop-in replacement without layout changes, select a 16-SSOP substitute such as CD74HC595SM96 or SN74HC595DBR.

Q: What is the difference between CD74HC595SM96 and SN74HC595DBR?

A: Both are 16-SSOP packages with active product status. CD74HC595SM96 offers extended operating temperature range (-55°C ~ 125°C) versus SN74HC595DBR (-40°C ~ 85°C). Select CD74HC595SM96 for applications requiring operation below -40°C or above 85°C. For standard industrial temperature ranges, either part is suitable.

Q: Are all 74HC595 variants pin-compatible?

A: Yes. All listed substitutes maintain identical pin configuration and electrical function as 8-bit shift registers with serial-to-parallel conversion. Compatibility is determined by package type (SSOP or TSSOP), not by manufacturer.

Q: Why is the 74HC595DB,112 marked as obsolete?

A: The original Nexperia part has reached end-of-life status. However, the 74HC595 logic function remains in active production by multiple manufacturers (Texas Instruments, onsemi, Nexperia). Substitutes are readily available with superior or equivalent specifications.

Q: What does MSL Level 1 mean for moisture sensitivity?

A: MSL (Moisture Sensitivity Level) 1 indicates unlimited shelf life without moisture control requirements. All listed substitutes carry this rating, eliminating special storage or handling procedures.

Q: Can I mix manufacturers in the same design?

A: Yes. All substitutes meet identical electrical specifications for the 74HC595 function. Mixing manufacturers (Nexperia, Texas Instruments, onsemi) within the same design is electrically valid. Verify packaging consistency within each PCB assembly to avoid layout conflicts.
