74HC04DB-Q100J Equivalent & Substitute Parts

Part Overview

The 74HC04DB-Q100J is a 6-channel inverter logic IC manufactured by Nexperia USA Inc. in a 14-SSOP surface mount package. This component is classified as obsolete, though inventory remains available. The part operates across a 2V to 6V supply voltage range and is qualified to AEC-Q100 automotive standards. Due to its obsolete status, identifying functionally equivalent substitute parts is essential for ongoing design support and procurement continuity.

Substitute Part Grouping Explanation

Substitute parts for the 74HC04DB-Q100J are identified based on strict electrical and mechanical compatibility criteria. The following parameters determine substitution eligibility:

Electrical Compatibility Requirements:

• Logic Type: Inverter (6 channels, 1 input per channel)
• Voltage - Supply: 2V ~ 6V
• Current - Quiescent (Max): 2 µA
• Current - Output High, Low: 5.2mA, 5.2mA
• Input Logic Level - Low: 0.5V ~ 1.8V
• Input Logic Level - High: 1.5V ~ 4.2V
• Max Propagation Delay @ 6V, 50pF: 14ns or better
• Operating Temperature: -40°C minimum to 85°C minimum
• Base Product Number: 74HC04

Mechanical Compatibility Requirements:

• Mounting Type: Surface Mount
• Package compatibility: 14-pin SSOP or 14-pin TSSOP variants

Compliance Requirements:

• RoHS3 Compliant
• AEC-Q100 Qualified (automotive grade)

Two substitute parts meet these criteria with variations in package type and manufacturer.

Engineering Selection Recommendations

74HC04PW-Q100,118 (Nexperia USA Inc.)

This substitute maintains full electrical equivalence with the main part and carries active product status. It is manufactured by the same supplier as the original component and holds AEC-Q100 automotive qualification. The primary difference is the package type: 14-TSSOP (0.173", 4.40mm width) versus the original 14-SSOP (0.209", 5.30mm width). This narrower package requires PCB layout adjustment but offers no electrical performance change. Operating temperature range extends to 125°C, matching the original specification. This part is suitable for direct substitution where PCB footprint modification is acceptable.

SN74HC04DBR (Texas Instruments)

This substitute is manufactured by Texas Instruments and maintains identical package dimensions (14-SSOP) to the original part, eliminating PCB layout changes. Electrical parameters are equivalent with one exception: maximum propagation delay is specified at 16ns versus 14ns for the original. Operating temperature range is limited to -40°C ~ 85°C, which is narrower than the original -40°C ~ 125°C specification. This part carries active product status and ROHS3 compliance. AEC-Q100 qualification is not specified for this variant. This part is suitable for substitution where the reduced temperature range and slightly higher propagation delay are acceptable for the application.

Frequently Asked Questions (FAQ)

Q: Can 74HC04PW-Q100,118 replace 74HC04DB-Q100J without circuit modification?

A: Electrical substitution is direct. The 14-TSSOP package is narrower (4.40mm) than the original 14-SSOP (5.30mm), requiring PCB footprint modification. Pin configuration and electrical performance are identical.

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

A: Both are 14-pin surface mount packages with identical pin pitch and electrical characteristics. The TSSOP variant has a narrower body width (4.40mm vs 5.30mm), affecting PCB layout space requirements only.

Q: Is SN74HC04DBR suitable for automotive applications requiring AEC-Q100?

A: SN74HC04DBR carries active product status and ROHS3 compliance. AEC-Q100 qualification is not specified in the provided data. Verify automotive qualification requirements against application specifications before selection.

Q: What is the impact of the 16ns propagation delay in SN74HC04DBR versus 14ns in the original?

A: The 2ns difference represents a 14% increase in maximum propagation delay. This affects timing-critical applications. Verify that system timing margins accommodate this specification before substitution.

Q: Are all three parts (original and both substitutes) RoHS3 compliant?

A: Yes. The original 74HC04DB-Q100J and both substitute parts (74HC04PW-Q100,118 and SN74HC04DBR) are ROHS3 compliant.

Q: Which substitute is recommended for new designs?

A: Selection depends on application constraints. For automotive AEC-Q100 applications with extended temperature requirements (-40°C ~ 125°C), use 74HC04PW-Q100,118 with PCB layout modification. For applications where package footprint must remain unchanged and reduced temperature range is acceptable, use SN74HC04DBR.
