74HC00DB,112 NAND Gate IC Equivalent & Substitute Parts

Part Overview

The 74HC00DB,112 is a quad 2-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 substitute parts necessary for new designs and production continuity. The 74HC00 series represents a standard logic family with multiple manufacturer variants and package options available in active production status.

Substitute Part Grouping Explanation

Substitution for the 74HC00DB,112 is determined by the following criteria:

Functional Equivalence: All substitute parts maintain identical logic function (quad 2-input NAND gate), circuit count (4), and input configuration (2 inputs per gate).

Electrical Compatibility: All substitutes operate within the same supply voltage range (2V to 6V) and maintain compatible input/output logic levels.

Package Compatibility: Substitutes are grouped by package type—14-SSOP (same as original) or 14-TSSOP (alternative surface mount option with different physical dimensions).

Thermal Operating Range: The original part specifies -40°C to 125°C. Substitutes with -40°C to 85°C range are functionally compatible for most applications but have a narrower upper temperature limit.

Compliance: All substitutes maintain ROHS3 compliance and EAR99 export classification matching the original part.

Engineering Selection Recommendations

Direct Package Match (14-SSOP): The SN74HC00DBR from Texas Instruments provides identical package dimensions to the original 74HC00DB,112, enabling direct PCB layout compatibility without redesign. This part is in active production status with ROHS3 compliance.

Package Upgrade Option (14-TSSOP): The 74HC00PW,118 from Nexperia USA Inc. offers the same manufacturer as the original part with active product status and full temperature range (-40°C to 125°C). The 14-TSSOP package is narrower (4.40mm vs 5.30mm width), requiring PCB layout modification but offering improved space efficiency.

Automotive Grade Alternatives: The SN74HC00QPWRQ1 and SN74HC00QPWRG4Q1 from Texas Instruments include AEC-Q100 automotive qualification and maintain the full -40°C to 125°C operating range, suitable for applications requiring automotive-grade components.

Active Production Priority: All recommended substitutes maintain active production status except SN74HC00PW (discontinued at DiGi Electronics). Prioritize parts with active status for long-term supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can I use a 14-TSSOP package substitute on a PCB designed for 14-SSOP?

A: No. While both are surface mount packages with 14 pins, the 14-TSSOP is narrower (4.40mm vs 5.30mm width) and has different pin spacing. PCB layout modification is required. The SN74HC00DBR maintains the original 14-SSOP footprint for direct substitution.

Q: What is the difference between the Nexperia and Texas Instruments versions?

A: Both manufacturers produce functionally equivalent 74HC00 NAND gates. The Nexperia 74HC00PW,118 maintains the original quiescent current specification (40 µA) and propagation delay (7ns). Texas Instruments variants (SN74HC00 series) show improved quiescent current (2 µA) but longer propagation delay (15ns). Both are ROHS3 compliant.

Q: Is the MM74HC00MTCX from Fairchild Semiconductor a suitable replacement?

A: The MM74HC00MTCX is functionally compatible but has a narrower operating temperature range (-40°C to 85°C vs -40°C to 125°C). Use this part only if your application does not require operation above 85°C. It uses the 14-TSSOP package, requiring PCB layout changes.

Q: Why do some substitutes have different propagation delay specifications?

A: The original 74HC00DB,112 specifies 7ns propagation delay at 6V with 50pF load. Texas Instruments and Fairchild variants specify 15ns under the same conditions. This difference reflects manufacturing process variations between suppliers. Both meet the 74HC00 logic family standard but have different speed grades.

Q: Are the automotive-qualified parts (QPWRQ1, QPWRG4Q1) suitable for non-automotive applications?

A: Yes. Automotive-qualified parts exceed standard industrial requirements and are fully compatible with non-automotive designs. They provide additional reliability margin and are suitable for any application requiring the 74HC00 NAND gate function.

Q: What is the moisture sensitivity level (MSL) for these parts?

A: All listed substitutes have MSL 1 (Unlimited), indicating no moisture sensitivity. These parts can be stored and handled without special moisture control measures.
