Substitute Part Grouping Explanation

Substitution of the CD74HC30MG4 is determined by strict equivalence across the following critical parameters:

Logic Type: NAND Gate (1 channel, 8 inputs)
Voltage Supply Range: 2V ~ 6V
Current Specifications: Quiescent 2 µA max; Output 5.2mA high/low
Input Logic Levels: Low 0.5V ~ 1.8V; High 1.5V ~ 4.2V
Package: 14-SOIC form factor
RoHS3 Compliance and MSL Level 1

All substitute parts listed maintain these core electrical and mechanical parameters. Variations in propagation delay (22ns vs. 30ns), operating temperature range (-55°C ~ 125°C vs. -40°C ~ 125°C), packaging format (Cut Tape, Tube, Tape & Reel), and manufacturer do not affect functional substitution within standard logic circuit applications.

Engineering Selection Recommendations

Primary Recommendation: CD74HC30M96

CD74HC30M96 is the direct active equivalent from Texas Instruments. It maintains identical electrical specifications to the CD74HC30MG4, including propagation delay of 22ns and operating temperature range of -55°C ~ 125°C. Available in Cut Tape and Digi-Reel packaging with 6851 units in stock, this part provides the most direct substitution path.

Secondary Recommendations:

74HC30D,653 and 74HC30D-Q100J from Nexperia USA Inc. are active alternatives with identical electrical performance. Both are available in Tape & Reel packaging. The operating temperature range is narrower (-40°C ~ 125°C), which is acceptable for most commercial and industrial applications. The 74HC30D-Q100J carries AEC-Q100 automotive qualification, suitable for automotive-grade applications.

MC74HC30ADR2G from onsemi is an active alternative with identical supply voltage, quiescent current, and output current specifications. Propagation delay is 30ns (8ns slower than the original), which remains within acceptable limits for standard logic applications. This part is available in Tape & Reel packaging.

Avoid:

MC74HC30ADG (onsemi) is marked as Obsolete and should not be selected for new designs despite current inventory availability.

CD74HC30M (Texas Instruments) is discontinued at DiGi Electronics and should be avoided in favor of the active CD74HC30M96.

Frequently Asked Questions (FAQ)

Q: Can I use 74HC30D,653 as a direct replacement for CD74HC30MG4?

A: Yes. Both parts are electrically equivalent NAND gate ICs with identical logic type, input/output specifications, and package form factor. The operating temperature range of 74HC30D,653 is -40°C ~ 125°C versus -55°C ~ 125°C for the original. This difference is not significant for standard commercial and industrial applications operating above -40°C.

Q: What is the difference between CD74HC30M96 and MC74HC30ADR2G?

A: Both are functionally equivalent 8-input NAND gates in 14-SOIC packages. The primary difference is propagation delay: CD74HC30M96 specifies 22ns while MC74HC30ADR2G specifies 30ns at 6V with 50pF load. For most logic applications, this 8ns difference is not critical. CD74HC30M96 is preferred if timing margins are tight.

Q: Is the 74HC30D-Q100J suitable for automotive applications?

A: Yes. The 74HC30D-Q100J carries AEC-Q100 qualification and is specifically designed for automotive-grade applications. It maintains all electrical equivalence to the CD74HC30MG4 while meeting automotive reliability standards.

Q: Does packaging format affect electrical performance?

A: No. Cut Tape, Tube, and Tape & Reel packaging formats are mechanical variations only. They do not affect the electrical characteristics or functional performance of the IC. Selection should be based on assembly process requirements and inventory management.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL Level 1 (Unlimited moisture sensitivity), matching the original CD74HC30MG4 specifications.

Q: Can I use MC74HC30ADG for new production?

A: No. MC74HC30ADG is marked as Obsolete. While it is electrically equivalent, obsolete parts should not be selected for new designs due to uncertain long-term availability and supply chain risk.
