Substitute Part Grouping Explanation

Substitution eligibility for the 74HC175N,652 is determined by strict adherence to the following electrical and mechanical parameters:

Core Compatibility Criteria:

• Series: 74HC (CMOS logic family)
• Type: D-Type Flip-Flop
• Configuration: 1 Element, 4 Bits per Element
• Output Type: Complementary
• Trigger Type: Positive Edge
• Package: 16-DIP (0.300", 7.62mm)
• Mounting: Through Hole
• Voltage Supply Range: 2V ~ 6V (minimum overlap required)
• Current Output: 5.2mA High and Low (matching specification)

Identified Substitute Parts:

1. CD74HC175E (Harris Corporation) – Direct functional equivalent
2. SN74HC175AN (Texas Instruments) – Manufacturer-recommended substitute
3. SN74HC175N (Texas Instruments) – Manufacturer-recommended substitute

All three substitute parts meet the core compatibility criteria and maintain electrical and mechanical interchangeability with the original 74HC175N,652.

Parameter Comparison

Engineering Selection Recommendations

For Active Production and New Designs: SN74HC175N (Texas Instruments) is the preferred substitute. This part carries active product status, ensuring long-term availability and supply chain stability. It maintains ROHS3 compliance and provides the lowest propagation delay (26ns @ 6V, 50pF) among all options, supporting higher-speed applications. The Texas Instruments 74HC175 series is the industry-standard replacement for obsolete 74HC175 variants.

For Legacy System Maintenance: SN74HC175AN (Texas Instruments) serves as an alternative active-status option. While operating temperature range is limited to -40°C ~ 85°C (compared to the original -40°C ~ 125°C), this part maintains full electrical compatibility and ROHS3 compliance for systems operating within standard industrial temperature ranges.

For Inventory Continuity: CD74HC175E (Harris Corporation) provides functional equivalence but carries obsolete product status and RoHS non-compliance. This part is suitable only for legacy system repairs where original specifications must be matched exactly and regulatory compliance is not a requirement.

Frequently Asked Questions (FAQ)

Q: Can I use SN74HC175N as a direct replacement for 74HC175N,652? A: Yes. Both parts share identical functional specifications, package configuration (16-DIP), and electrical parameters (supply voltage 2V ~ 6V, output current 5.2mA, complementary outputs). The primary difference is product status: SN74HC175N is active, while 74HC175N,652 is obsolete. SN74HC175N is the recommended substitute for new designs and ongoing production.

Q: What is the difference between SN74HC175AN and SN74HC175N? A: Both are Texas Instruments 74HC175 variants with identical electrical specifications and active product status. The primary difference is operating temperature range: SN74HC175AN operates -40°C ~ 85°C, while SN74HC175N operates -40°C ~ 85°C as well. Both are suitable for standard industrial applications. Packaging may differ (tube vs. other formats), so verify supplier specifications for your procurement requirements.

Q: Is CD74HC175E compatible with my circuit? A: CD74HC175E maintains full electrical and mechanical compatibility with 74HC175N,652. However, this Harris Corporation part is obsolete and RoHS non-compliant. Use CD74HC175E only for legacy system repairs where original specifications are mandatory and regulatory compliance is not applicable. For new designs, use active-status Texas Instruments alternatives.

Q: What happens if my application requires the full -40°C ~ 125°C temperature range? A: The original 74HC175N,652 and CD74HC175E both support -40°C ~ 125°C operation. However, both are obsolete. If extended temperature range is critical, evaluate circuit redesign or consult with Texas Instruments regarding specialized temperature-grade variants. Standard SN74HC175 series parts operate -40°C ~ 85°C.

Q: Are all substitute parts in the same 16-DIP package? A: Yes. All substitute parts (CD74HC175E, SN74HC175AN, SN74HC175N) use 16-DIP (0.300", 7.62mm) through-hole packaging, ensuring mechanical and pin-compatible installation without PCB modifications.

Q: Which substitute has the best propagation delay performance? A: SN74HC175N provides the lowest propagation delay at 26ns @ 6V, 50pF, compared to 30ns for both 74HC175N,652 and CD74HC175E. This makes SN74HC175N suitable for higher-speed timing-critical applications.
