Substitute Part Grouping Explanation

Substitution of the SN74HC652NTG4 is determined by strict equivalence across the following critical parameters:

• Logic Type: Transceiver, Non-Inverting
• Number of Elements: 1
• Number of Bits per Element: 8
• Output Type: 3-State
• Current - Output High, Low: 7.8mA, 7.8mA
• Voltage - Supply: 2V ~ 6V
• Operating Temperature: -40°C ~ 85°C (TA)
• Series: 74HC
• Base Product Number: 74HC652
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

The SN74HC652DWR qualifies as a direct functional substitute. Both components share identical electrical specifications, logic architecture, and compliance certifications. The primary difference is packaging: the SN74HC652NTG4 uses through-hole 24-DIP mounting, while the SN74HC652DWR uses surface-mount 24-SOIC packaging. This distinction requires PCB redesign or adapter solutions for direct board-level replacement.

Parameter Comparison

Engineering Selection Recommendations

The SN74HC652DWR is the manufacturer-recommended substitute for the SN74HC652NTG4. Both components maintain identical electrical performance, logic functionality, and compliance certifications. The SN74HC652DWR carries Active product status, ensuring continued availability and manufacturing support.

Selection between these parts depends on PCB architecture and mounting requirements. The SN74HC652NTG4 is suitable for through-hole applications on existing boards. The SN74HC652DWR is appropriate for new designs or boards supporting surface-mount technology. Both components meet ROHS3 compliance and carry unlimited moisture sensitivity classification, making them suitable for standard industrial and commercial environments.

Frequently Asked Questions (FAQ)

Q: Can the SN74HC652DWR directly replace the SN74HC652NTG4 on an existing PCB?

A: Electrical substitution is complete. However, physical replacement requires PCB modification or an adapter solution due to different mounting types: the original uses through-hole 24-DIP packaging, while the substitute uses surface-mount 24-SOIC packaging.

Q: Are the electrical specifications identical between these parts?

A: Yes. Both components share identical logic type, bit configuration, output current ratings, supply voltage range, and operating temperature specifications. They are functionally equivalent at the circuit level.

Q: What is the significance of the product status difference?

A: The SN74HC652NTG4 is Obsolete, indicating discontinued manufacturing. The SN74HC652DWR is Active, meaning Texas Instruments continues production and support. For new designs or long-term production, the Active substitute is the appropriate choice.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the SN74HC652NTG4 and SN74HC652DWR are ROHS3 compliant with unlimited moisture sensitivity classification (MSL 1). They meet identical environmental and regulatory requirements.

Q: What packaging considerations apply to substitution?

A: The SN74HC652NTG4 uses 24-pin DIP (0.300", 7.62mm) for through-hole mounting. The SN74HC652DWR uses 24-pin SOIC (0.295", 7.50mm Width) for surface-mount applications. Pin count and electrical pinout are equivalent, but physical footprints differ significantly.
