74HC30DB,118 NAND Gate IC Equivalent & Substitute Parts

Part Overview

The 74HC30DB,118 is a single-channel 8-input NAND gate logic IC manufactured by Nexperia USA Inc. in a 14-SSOP surface mount package. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The 74HC30 series represents a standard logic gate function with consistent electrical characteristics across multiple manufacturers and package variants, enabling direct functional substitution where package and environmental requirements align.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74HC30DB,118 is determined by the following critical parameters:

• Logic Function: All substitute parts must implement a single-channel 8-input NAND gate
• Electrical Characteristics: Supply voltage range (2V ~ 6V), quiescent current (2 µA max), output current (5.2mA), input logic levels, and propagation delay (22ns @ 6V, 50pF) must remain consistent
• Package Compatibility: The original 14-SSOP package may be substituted with 14-TSSOP (functionally equivalent surface mount packages with different pitch specifications)
• Environmental Ratings: Operating temperature range, RoHS compliance, and MSL rating must meet or exceed the original specification
• Manufacturer Availability: Active or discontinued status affects long-term procurement viability

The substitute parts listed below maintain electrical equivalence within the 74HC30 logic family while offering alternative packaging formats and manufacturer sources.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: CD74HC30PWR (Texas Instruments)

CD74HC30PWR is the recommended substitute for the 74HC30DB,118. This part maintains active product status, ensuring long-term availability and supply chain stability. It is ROHS3 compliant and carries an extended operating temperature range (-55°C ~ 125°C), which exceeds the original specification. The 14-TSSOP package is functionally equivalent to 14-SSOP for surface mount applications, with a narrower pitch (0.173" vs 0.209") that accommodates modern PCB design standards.

Secondary Substitute: 74HC30PW,118 (NXP Semiconductors)

74HC30PW,118 offers active product status and maintains the same base product number as the original part. This option provides continuity within the NXP/Nexperia product family. Packaging details are not fully specified in available data, requiring verification against PCB layout requirements.

Alternative Substitutes: CD74HC30PW and CD74HC30PWT (Texas Instruments)

Both CD74HC30PW and CD74HC30PWT are Texas Instruments variants in 14-TSSOP packaging. CD74HC30PW is discontinued at DiGi Electronics, limiting procurement viability. CD74HC30PWT is also discontinued at DiGi Electronics. These options are suitable only for applications where existing inventory is available or where alternative distribution channels provide supply.

Package Consideration

The transition from 14-SSOP to 14-TSSOP requires PCB layout verification. Both packages are surface mount with 14 pins, but the TSSOP variant has a reduced pitch (0.173" vs 0.209" width). Existing PCB footprints designed for SSOP will not accommodate TSSOP without redesign.

Frequently Asked Questions (FAQ)

Q: Can I directly replace 74HC30DB,118 with CD74HC30PWR on my PCB?

A: Electrical substitution is direct. However, the package change from 14-SSOP to 14-TSSOP requires PCB footprint modification. The pin count and function are identical, but the physical dimensions differ. Verify your PCB layout supports the narrower TSSOP pitch before implementation.

Q: What is the difference between 14-SSOP and 14-TSSOP packages?

A: Both are 14-pin surface mount packages. SSOP (Shrink Small Outline Package) has a body width of 0.209" (5.30mm), while TSSOP (Thin Shrink Small Outline Package) has a body width of 0.173" (4.40mm). TSSOP represents a more compact design standard. Pin pitch and electrical function remain equivalent.

Q: Why is the 74HC30DB,118 marked as obsolete?

A: The original Nexperia part is obsolete, but the 74HC30 logic function remains in active production through multiple manufacturers. Substitute parts from Texas Instruments and NXP provide equivalent functionality with current product status.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification, meeting environmental and hazardous substance restrictions.

Q: What is the operating temperature range difference between the original and substitutes?

A: The 74HC30DB,118 operates from -40°C to 125°C. Texas Instruments substitutes (CD74HC30PW, CD74HC30PWR, CD74HC30PWT) extend the lower limit to -55°C, providing a wider operating range suitable for industrial and military applications.

Q: Can I use 74HC30PW,118 as a direct replacement?

A: Electrically, yes. The 74HC30PW,118 maintains the same logic function and electrical characteristics. However, packaging specifications are not fully detailed in available data. Confirm package compatibility with your PCB design before procurement.

Q: Which substitute offers the best long-term availability?

A: CD74HC30PWR (Texas Instruments) is the optimal choice for long-term availability, as it maintains active product status. Current inventory levels (19,432 pcs) and established distribution channels support sustained procurement.
