Engineering Selection Recommendations
For Through-Hole PCB Designs (Direct Pin-Compatible Substitutes):
CD74HC164E, 74HC164D14, and SN74HC164N are pin-compatible replacements in 14-DIP packaging. All three are active products with ROHS3 compliance and REACH unaffected status. CD74HC164E offers extended operating temperature range (-55°C to 125°C) compared to the main part (-40°C to 125°C). SN74HC164N and 74HC164D14 maintain the original temperature specification.
For Surface-Mount PCB Designs (Functional Equivalent with Package Change):
74HC164D,653 provides functional equivalence with surface-mount 14-SOIC packaging. This substitution requires PCB layout modification but maintains all electrical parameters and compliance certifications. This part is recommended for new designs prioritizing surface-mount assembly.
Product Status Advantage:
All substitute parts carry active product status, ensuring continued manufacturing support, documented availability, and supply chain reliability. This contrasts with the obsolete main part, which faces potential discontinuation and supply constraints.
Frequently Asked Questions (FAQ)
Q: Can CD74HC164E replace 74HC164N,652 in existing designs?
A: Yes. CD74HC164E is pin-compatible in 14-DIP packaging and matches all functional parameters. The extended operating temperature range (-55°C to 125°C) provides additional margin beyond the original specification (-40°C to 125°C).
Q: What is the difference between through-hole and surface-mount substitutes?
A: CD74HC164E, 74HC164D14, and SN74HC164N use 14-DIP through-hole packaging, compatible with existing PCB designs. 74HC164D,653 uses 14-SOIC surface-mount packaging, requiring PCB redesign but offering smaller footprint and automated assembly compatibility.
Q: Are all substitutes RoHS3 compliant?
A: Yes. All substitute parts listed are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
Q: Which substitute has the widest operating temperature range?
A: CD74HC164E operates from -55°C to 125°C, providing 15°C additional low-temperature margin compared to the main part and other substitutes at -40°C to 125°C.
Q: Can I use 74HC164D,653 as a direct replacement on existing through-hole boards?
A: No. 74HC164D,653 uses 14-SOIC surface-mount packaging and cannot be directly installed on through-hole PCBs. Through-hole designs require CD74HC164E, 74HC164D14, or SN74HC164N.
Q: Are all substitutes available in high volume?
A: Yes. Inventory levels for active substitutes range from 1,900 to 40,100 pieces, providing adequate supply for production requirements.
