Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74HC595N,112 is determined by the following critical parameters:

• Base Product Number: All substitutes must be 74HC595 series devices
• Logic Type & Function: Shift register with serial-to-parallel conversion capability
• Bit Configuration: 1 element, 8 bits per element
• Output Type: Tri-state output
• Supply Voltage: 2V ~ 6V operating range
• Package Compatibility: 16-DIP form factor with 0.300" (7.62mm) pitch for through-hole mounting, or 16-SOIC for surface-mount equivalents
• Compliance: ROHS3 compliant, REACH unaffected

Substitutes are grouped into two categories: direct pin-compatible through-hole replacements (16-DIP/16-PDIP) and surface-mount alternatives (16-SOIC) for different assembly requirements.

Engineering Selection Recommendations

For Through-Hole Applications (Direct Pin Replacement):

CD74HC595E and SN74HC595N are both active production alternatives to the obsolete 74HC595N,112. Both maintain the 16-DIP package format and are ROHS3 compliant. CD74HC595E offers an extended operating temperature range (-55°C to 125°C) compared to the original part (-40°C to 125°C). SN74HC595N operates within -40°C to 85°C, which is narrower than the original specification. Selection between these two depends on the specific temperature requirements of the application.

For Surface-Mount Applications (Package Conversion):

74HC595D,118 from Nexperia provides functional equivalence in a 16-SOIC surface-mount package. This part maintains the full operating temperature range (-40°C to 125°C) and is recommended when transitioning from through-hole to surface-mount assembly. The 16-SOIC package requires PCB layout and assembly process modifications.

All substitutes maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with the original part.

Frequently Asked Questions (FAQ)

Q: Can CD74HC595E replace 74HC595N,112 in existing through-hole designs?

A: Yes. CD74HC595E is pin-compatible in the 16-DIP package and maintains identical electrical specifications (2V ~ 6V supply, tri-state output, 8-bit serial-to-parallel function). The extended temperature range (-55°C to 125°C) provides additional margin beyond the original -40°C to 125°C specification.

Q: What is the difference between CD74HC595E and SN74HC595N?

A: Both are 16-DIP through-hole packages with identical pin configurations. CD74HC595E operates from -55°C to 125°C, while SN74HC595N operates from -40°C to 85°C. For applications requiring the full -40°C to 125°C range, CD74HC595E is the appropriate choice.

Q: Can 74HC595D,118 be used as a direct replacement?

A: 74HC595D,118 is functionally equivalent but uses a 16-SOIC surface-mount package instead of 16-DIP through-hole. This requires PCB redesign and different assembly processes. It is suitable for new designs or board revisions transitioning to surface-mount technology.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All listed substitutes (CD74HC595E, SN74HC595N, and 74HC595D,118) are ROHS3 compliant and REACH unaffected, matching the regulatory status of the original 74HC595N,112.

Q: Which substitute has the best availability?

A: SN74HC595N has the highest inventory (4,670 pcs), followed by CD74HC595E (1,823 pcs) and 74HC595D,118 (1,000,100 pcs in cut tape and digi-reel formats). Availability should be confirmed with your supplier for current stock levels.
