Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74HC151D,652 is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Circuit configuration: 1 x 8:1 multiplexer function
• Voltage supply range: 2V ~ 6V
• Package type: 16-SOIC (0.154", 3.90mm Width)
• Mounting type: Surface Mount
• Output current capability: minimum 5.2mA (high and low)

Substitution Categories:

Direct Substitutes maintain all electrical and mechanical parameters within the specified ranges. These parts are pin-compatible and functionally equivalent with no design modifications required.

Upgrade Substitutes offer enhanced specifications such as extended temperature ranges (-55°C ~ 125°C vs. -40°C ~ 125°C) or improved product status (Active vs. Obsolete). These parts are fully backward compatible and provide superior performance margins.

Similar Substitutes share the same base circuit function and package but may have different output current ratings (7.8mA vs. 5.2mA) or narrower operating temperature ranges (-40°C ~ 85°C). These require verification that the higher output current does not create thermal or power supply concerns in the application.

Parameter Comparison

Engineering Selection Recommendations

Preferred Direct Substitute: MC74HC151ADR2G (onsemi) is the primary recommended substitute. It maintains identical electrical specifications (5.2mA output current, 2V ~ 6V supply) while offering an extended operating temperature range (-55°C ~ 125°C) and active product status. ROHS3 compliance ensures regulatory alignment with modern manufacturing standards.

Preferred Upgrade Substitute: CD74HC151M96 (Texas Instruments) provides the same electrical performance as the original part with extended temperature range and active product status. ROHS3 compliance and Tape & Reel packaging support high-volume production requirements.

Alternative Substitutes with Higher Output Current: SN74HC151DR (Texas Instruments) is an active product offering 7.8mA output current capability, which exceeds the original 5.2mA specification. This part is suitable for applications requiring higher drive capability. The narrower operating temperature range (-40°C ~ 85°C) must be verified against application requirements.

SN74HC151QDRQ1 (Texas Instruments) is an automotive-grade variant (AEC-Q100 qualified) with extended temperature range (-40°C ~ 125°C) and 7.8mA output current. This part is appropriate for automotive and high-reliability applications.

Obsolete Alternatives: CD74HC151M (Harris Corporation) and SN74HC151D (Texas Instruments) are obsolete or discontinued products. These should be avoided for new designs unless existing inventory is available and long-term supply is not a concern.

Frequently Asked Questions (FAQ)

Q: Can I use SN74HC151DR as a direct replacement for 74HC151D,652?

A: SN74HC151DR is functionally compatible and pin-compatible. However, it has higher output current (7.8mA vs. 5.2mA) and a narrower operating temperature range (-40°C ~ 85°C vs. -40°C ~ 125°C). Verify that your application does not require operation above 85°C and that the higher output current does not create power supply or thermal issues.

Q: What is the difference between MC74HC151ADR2G and CD74HC151M96?

A: Both parts maintain the original 5.2mA output current specification and 2V ~ 6V supply range. MC74HC151ADR2G (onsemi) and CD74HC151M96 (Texas Instruments) differ in manufacturer and packaging format. Both are active products with ROHS3 compliance and extended temperature range (-55°C ~ 125°C).

Q: Is the 16-SOIC package identical across all substitute parts?

A: Yes. All substitute parts use the 16-SOIC (0.154", 3.90mm Width) package, ensuring mechanical and electrical pin compatibility. No PCB layout modifications are required.

Q: Why is SN74HC151QDRQ1 more expensive than other substitutes?

A: SN74HC151QDRQ1 is an automotive-grade component qualified to AEC-Q100 standards. This qualification requires additional testing and documentation, resulting in higher cost. Use this part only if automotive-grade reliability is required.

Q: Can I use CD74HC151M for new production?

A: CD74HC151M is obsolete and RoHS non-compliant. It should not be used for new designs. Use MC74HC151ADR2G or CD74HC151M96 instead, both of which are active products with ROHS3 compliance.

Q: What is the minimum output current I should expect from these parts?

A: The original 74HC151D,652 specifies 5.2mA output current. MC74HC151ADR2G and CD74HC151M96 maintain this specification. SN74HC151DR, SN74HC151DT, and SN74HC151QDRQ1 provide 7.8mA, which is higher and fully backward compatible.
