CD74HC30MT NAND Gate IC Equivalent & Substitute Parts

Part Overview

The CD74HC30MT is a single-channel 8-input NAND gate logic IC manufactured by Texas Instruments in a 14-SOIC surface mount package. This part is discontinued at DiGi Electronics, making equivalent substitutes necessary for ongoing production and maintenance applications. The 74HC30 logic family provides standard NAND gate functionality across multiple manufacturers, with several active alternatives available that maintain electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution of the CD74HC30MT is determined by strict equivalence across the following parameters:

Logic type (NAND Gate with 1 channel, 8 inputs)
Electrical specifications (voltage supply, quiescent current, output current, input logic levels)
Package type (14-SOIC surface mount)
Compliance certifications (RoHS3, REACH Unaffected)
Moisture sensitivity level (MSL 1)

Substitute parts are grouped into two categories:

Parametric Equivalents: Parts with identical electrical performance and packaging. CD74HC30M96 (Texas Instruments, Cut Tape packaging) maintains all electrical specifications and 14-SOIC package compatibility.

Manufacturer Recommended Alternatives: Parts from alternative manufacturers (Nexperia, onsemi) that meet or exceed the electrical specifications. These include 74HC30D,653, 74HC30D-Q100J, MC74HC30ADR2G, and MC74HC30ADG. Variations in propagation delay (22ns vs. 30ns) and operating temperature ranges are noted but do not prevent functional substitution within the 74HC30 logic family.

Engineering Selection Recommendations

Primary Substitute: CD74HC30M96 (Texas Instruments) is the direct parametric equivalent with identical electrical performance, operating temperature range, and propagation delay. This part maintains continuity with the original manufacturer and is currently active in production.

Secondary Substitutes: 74HC30D,653 and 74HC30D-Q100J (Nexperia) are functionally equivalent with matching electrical specifications. The 74HC30D-Q100J includes AEC-Q100 automotive qualification, suitable for applications requiring automotive-grade components. Both Nexperia parts operate at -40°C minimum temperature versus -55°C for the original, which may be a consideration for extended temperature range applications.

Alternative Substitute: MC74HC30ADR2G (onsemi) is active and available in Tape & Reel packaging. This part exhibits 30ns propagation delay versus 22ns for the original, which remains within acceptable timing margins for standard logic applications. MC74HC30ADG (onsemi) is obsolete and should be avoided for new designs.

Compliance: All recommended substitutes maintain ROHS3 compliance, REACH unaffected status, and MSL 1 moisture sensitivity rating, ensuring regulatory and environmental compatibility with the original specification.

Frequently Asked Questions (FAQ)

Q: Can CD74HC30M96 be used as a direct replacement for CD74HC30MT?

A: Yes. CD74HC30M96 is a parametric equivalent with identical electrical specifications, operating temperature range (-55°C to 125°C), and propagation delay (22ns @ 6V, 50pF). The only difference is packaging format (Cut Tape & Digi-Reel versus Tape & Reel), which does not affect component functionality or PCB assembly compatibility.

Q: What is the difference between the Nexperia 74HC30D,653 and 74HC30D-Q100J?

A: Both parts are electrically identical with 22ns propagation delay and 14-SOIC packaging. The 74HC30D-Q100J includes AEC-Q100 automotive qualification and is suitable for automotive applications. The 74HC30D,653 is the standard industrial grade version. The 74HC30D-Q100J operates at -40°C minimum temperature, while 74HC30D,653 also operates at -40°C minimum.

Q: Why do onsemi parts (MC74HC30ADR2G, MC74HC30ADG) have 30ns propagation delay instead of 22ns?

A: The 30ns propagation delay is within the 74HC logic family specification and does not prevent functional substitution. This timing difference is acceptable for standard logic applications where propagation delay margins are not critical. Applications with tight timing constraints should verify compatibility with system requirements.

Q: Is MC74HC30ADG suitable for new designs?

A: No. MC74HC30ADG is marked as obsolete and should not be selected for new designs. MC74HC30ADR2G (active status) is the recommended onsemi alternative.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the original CD74HC30MT specification.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes. All substitute parts use the 14-SOIC package with identical pin configuration and electrical characteristics. PCB layout and assembly processes require no modification for substitution.
