74LVC02APW-Q100J NOR Gate IC Equivalent & Substitute Parts

Part Overview

The 74LVC02APW-Q100J is a 4-channel, 2-input NOR gate logic IC manufactured by Nexperia USA Inc. in a 14-TSSOP surface mount package. This component operates across a wide supply voltage range of 1.2V to 3.6V and is qualified to AEC-Q100 automotive standards. The part is currently in active production status with 1179 units available in stock. Substitute parts are necessary when the primary part becomes unavailable, when alternative sourcing is required for supply chain resilience, or when design flexibility demands component options from different manufacturers while maintaining functional and electrical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 74LVC02APW-Q100J is determined by the following critical parameters:

• Logic function: 4-channel, 2-input NOR gate
• Package type: 14-TSSOP surface mount
• Supply voltage compatibility: Minimum 1.2V to 3.6V range
• Output drive capability: 24mA minimum for both high and low states
• Propagation delay: Maximum 5.5ns at 3.3V, 50pF load
• Operating temperature range: -40°C to 125°C minimum
• Moisture sensitivity: MSL 1 (Unlimited)
• RoHS compliance: ROHS3 Compliant

Substitute parts are grouped into two categories: parametric equivalents (identical electrical specifications and packaging) and similar parts (compatible function with minor parameter variations that do not affect circuit operation within specified conditions).

Parameter Comparison

Engineering Selection Recommendations

74LVC02APW,118 (NXP Semiconductors): This part maintains identical supply voltage range and output drive specifications as the primary part. The quiescent current specification of 40 µA represents a minor increase over the 10 µA maximum of the 74LVC02APW-Q100J. Propagation delay extends to 5.5ns, which remains within acceptable timing margins for most applications. This part is available in bulk packaging and carries active product status. It lacks automotive grade and AEC-Q100 qualification, making it suitable for non-automotive applications only.

NLV74LCX02DTR2G (onsemi): This part operates within a narrower supply voltage range of 2V to 3.6V, which excludes operation below 2V. It maintains the 10 µA quiescent current and 24mA output drive specifications. The operating temperature range is limited to -40°C to 85°C, which is 40°C below the primary part's upper limit. This part carries automotive grade and AEC-Q100 qualification. Product status is obsolete, indicating limited future availability. Use only when supply chain constraints require and when the narrower voltage and temperature ranges are acceptable for the application.

SN74LVC02AMPWREP (Texas Instruments): This part operates within a 2V to 3.6V supply voltage range and maintains 10 µA quiescent current and 24mA output drive. Propagation delay is specified at 5.5ns. The operating temperature range extends to -55°C, providing 15°C additional low-temperature capability compared to the primary part. This part carries active product status and ROHS3 compliance. It lacks automotive grade and AEC-Q100 qualification. Use for non-automotive applications or when extended low-temperature operation is required.

Frequently Asked Questions (FAQ)

Q: Can the 74LVC02APW,118 be used as a direct replacement for the 74LVC02APW-Q100J in automotive applications?

A: No. The 74LVC02APW,118 lacks automotive grade designation and AEC-Q100 qualification. It is suitable only for non-automotive applications. For automotive designs, use either the primary part or the NLV74LCX02DTR2G, which carries AEC-Q100 qualification.

Q: What is the impact of the narrower supply voltage range in the NLV74LCX02DTR2G?

A: The NLV74LCX02DTR2G operates from 2V to 3.6V, excluding the 1.2V to 2V range supported by the 74LVC02APW-Q100J. If your circuit requires operation below 2V, this part is not suitable. Verify your application's minimum supply voltage before selection.

Q: Does the 5.5ns propagation delay of substitute parts affect circuit timing?

A: The substitute parts specify 5.5ns maximum propagation delay at 3.3V with 50pF load, compared to 4.4ns for the primary part. This 1.1ns difference is typically negligible in most logic applications. Verify timing margins in your specific circuit design to confirm acceptability.

Q: Why is the NLV74LCX02DTR2G listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. While inventory may remain available through distributors, future availability is not guaranteed. This part should be considered only when other options are exhausted and current stock is confirmed.

Q: Are all substitute parts pin-compatible with the 74LVC02APW-Q100J?

A: Yes. All substitute parts use the 14-TSSOP package with identical pin configuration and spacing (0.173", 4.40mm width). Pin-to-pin compatibility is confirmed across all listed substitutes.

Q: What is the significance of MSL 1 (Unlimited) moisture sensitivity?

A: MSL 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. All listed parts carry this specification, ensuring consistent handling requirements across substitutes.
