SN74AHC02PWRE4 Equivalent & Substitute Parts

Part Overview

The SN74AHC02PWRE4 is a NOR Gate IC with 4 channels and 2 inputs per channel, manufactured by Texas Instruments in a 14-TSSOP surface mount package. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The device operates across a 2V to 5.5V supply voltage range with a maximum propagation delay of 8.5ns at 5V with 50pF load, suitable for general-purpose logic applications requiring low-power operation.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the SN74AHC02PWRE4 is determined by strict equivalence across the following critical parameters:

• Logic Type: NOR Gate with 4 channels and 2 inputs per channel
• Package: 14-TSSOP surface mount form factor
• Voltage Supply Range: 2V ~ 5.5V minimum requirement
• Output Current Capability: 8mA minimum for both high and low states
• Quiescent Current: 2 µA maximum
• Propagation Delay: 8.5ns maximum at 5V with 50pF load
• Operating Temperature Range: -40°C ~ 125°C minimum
• RoHS3 Compliance and MSL Level 1

Substitute parts are grouped into three categories based on manufacturer and product status: MFR Recommended (Texas Instruments active equivalent), Direct Manufacturer alternatives (onsemi active equivalents), and Upgrade options (alternative manufacturers with compatible specifications).

Parameter Comparison

Engineering Selection Recommendations

SN74AHC02PWR (Texas Instruments) is the primary recommended substitute. It maintains identical electrical specifications to the obsolete SN74AHC02PWRE4 while offering active product status, ensuring long-term availability and supply chain stability. Both parts share the same base product number (74AHC02), operating temperature range (-40°C ~ 125°C), and packaging format. This part is available in Tape & Reel packaging with 5800 units in stock.

74VHC02MTCX and MC74VHC02DTR2G (onsemi) are direct manufacturer alternatives with active status. These parts meet all critical electrical parameters with improved propagation delay performance (7.5ns versus 8.5ns). The operating temperature range is limited to -40°C ~ 85°C, which is acceptable for applications not requiring the full -40°C ~ 125°C range. Both parts are available in high inventory quantities (36408 and 19800 units respectively).

74VHC02PW,118 (Nexperia USA Inc.) is an upgrade option maintaining the full -40°C ~ 125°C operating temperature range with improved propagation delay (7.5ns). This part offers compatibility with the original temperature specifications while providing enhanced performance characteristics. Inventory availability is limited at 781 units.

74AHC02PW,118 (NXP Semiconductors) is available as an upgrade option with extensive inventory (246743 units). Limited parameter data is provided for this part; full electrical specification verification is required before selection.

Selection should prioritize SN74AHC02PWR for direct replacement, with onsemi alternatives (74VHC02MTCX or MC74VHC02DTR2G) as secondary options when temperature range limitations are acceptable.

Frequently Asked Questions (FAQ)

Q: Can I use 74VHC02MTCX or MC74VHC02DTR2G as direct replacements for SN74AHC02PWRE4?

A: Yes, both onsemi parts are electrically compatible. All critical parameters match: 4-channel NOR gate configuration, 2 inputs per channel, 2V ~ 5.5V supply voltage, 8mA output current, and 2 µA quiescent current. The operating temperature range is reduced to -40°C ~ 85°C. Propagation delay is improved to 7.5ns. Verify your application does not require operation above 85°C before selection.

Q: What is the difference between SN74AHC02PWR and 74VHC02PW,118?

A: Both parts are NOR gate ICs in 14-TSSOP packages with identical logic configuration and supply voltage range. SN74AHC02PWR is manufactured by Texas Instruments with 8.5ns propagation delay and -40°C ~ 125°C operating range. 74VHC02PW,118 is manufactured by Nexperia with 7.5ns propagation delay and maintains the full -40°C ~ 125°C operating range. The Nexperia part offers improved speed performance.

Q: Are all substitute parts RoHS3 compliant?

A: Yes, all listed substitute parts are ROHS3 compliant with MSL Level 1 (Unlimited moisture sensitivity level), matching the original SN74AHC02PWRE4 specifications.

Q: Does packaging format differ between substitute options?

A: All substitute parts use the 14-TSSOP surface mount package with identical 0.173" width and 4.40mm dimensions. Packaging format variations exist only in supply method: Tape & Reel (TR), Cut Tape (CT) & Digi-Reel, or unspecified. These differences do not affect electrical or mechanical compatibility.

Q: Which substitute part has the best availability?

A: 74AHC02PW,118 (NXP Semiconductors) has the highest inventory at 246743 units. For parts with complete electrical specifications, 74VHC02MTCX (onsemi) offers 36408 units in stock.
