Key Parameters

Substitute Part Grouping Explanation

Substitution for the 74HC165N,652 is determined by the following critical parameters:

Electrical Compatibility: All substitute parts maintain identical logic function (8-bit shift register), output type (complementary), and supply voltage range (2V ~ 6V). These parameters ensure functional equivalence at the circuit level.

Mechanical Compatibility: Package type and mounting method are primary substitution criteria. The 74HC165N,652 uses a 16-DIP through-hole package. Direct pin-compatible substitutes must use the same 16-DIP package configuration.

Thermal Performance: Operating temperature range is a secondary consideration. The main part specifies -40°C ~ 125°C. Substitutes with equal or wider temperature ranges are acceptable.

Compliance & Status: All substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the original part's regulatory standing.

Parameter Comparison

Engineering Selection Recommendations

For Direct Pin-Compatible Replacement (Through-Hole 16-DIP):

CD74HC165E, SN74HC165N, and TC74HC165AP(F) are functionally equivalent through-hole substitutes. SN74HC165N offers the widest inventory availability (12,500 pcs) and maintains identical temperature specifications to the original part. CD74HC165E provides extended lower temperature operation (-55°C minimum) if thermal margin is required. TC74HC165AP(F) is suitable for applications with maximum operating temperature not exceeding 85°C.

For Surface-Mount Applications:

74HC165D,653 provides functional equivalence in a 16-SOIC surface-mount package. This part is recommended only when PCB redesign to surface-mount technology is feasible. All electrical parameters remain identical to the through-hole variants.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with the original 74HC165N,652 specification.

Frequently Asked Questions (FAQ)

Q: Can I use CD74HC165E as a direct replacement for 74HC165N,652?

A: Yes. CD74HC165E is pin-compatible in a 16-DIP package with identical electrical specifications. The extended operating temperature range (-55°C ~ 125°C) provides additional thermal margin compared to the original part's -40°C ~ 125°C range.

Q: What is the difference between SN74HC165N and TC74HC165AP(F)?

A: Both are 16-DIP through-hole packages with identical pin configuration and electrical function. The primary difference is operating temperature range: SN74HC165N operates -40°C ~ 125°C, while TC74HC165AP(F) operates -40°C ~ 85°C. Select based on application thermal requirements.

Q: Why is 74HC165D,653 listed as a substitute if it uses a different package?

A: 74HC165D,653 is a manufacturer-recommended equivalent that maintains all electrical specifications but uses a 16-SOIC surface-mount package instead of through-hole DIP. This part is suitable only for new designs or PCB revisions that accommodate surface-mount technology.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the regulatory requirements of the original 74HC165N,652.

Q: Which substitute has the best inventory availability?

A: SN74HC165N (Texas Instruments) has the highest inventory level at 12,500 pcs in stock, followed by 74HC165D,653 (Nexperia) at 351,671 pcs for the surface-mount variant.

Q: Can I use 74HC165D,653 in a through-hole PCB design?

A: No. 74HC165D,653 is a 16-SOIC surface-mount package and is not compatible with through-hole PCB layouts. Use CD74HC165E, SN74HC165N, or TC74HC165AP(F) for through-hole applications.
