CD74HC03M NAND Gate IC Equivalent & Substitute Parts

Part Overview

The CD74HC03M is a 4-channel, 2-input NAND gate IC manufactured by Texas Instruments in 14-SOIC surface mount packaging. This logic component features open drain outputs and operates across a 2V to 6V supply voltage range. The part is currently in Last Time Buy status, making identification of active equivalent and substitute parts essential for ongoing design support and procurement planning.

Substitute Part Grouping Explanation

Substitution of the CD74HC03M is determined by strict equivalence across the following parameters: logic type (NAND gate), circuit count (4 channels), input count (2 inputs per gate), output configuration (open drain), supply voltage range (2V ~ 6V), operating temperature range (-55°C ~ 125°C), and package type (14-SOIC surface mount). All substitute parts listed maintain these core electrical and mechanical specifications. Packaging format (tube, tape & reel, bulk, or cut tape) represents a secondary consideration and does not affect functional compatibility.

Engineering Selection Recommendations

For active production designs, CD74HC03M96 (Texas Instruments, Tape & Reel) provides direct functional equivalence with identical electrical performance and active product status. MC74HC03ADR2G and MC74HC03ADG (onsemi) are functionally compatible alternatives with active status; both exhibit slightly lower quiescent current (1 µA vs. 2 µA) and marginally extended propagation delay (20 ns vs. 17 ns at 6V, 50pF), which remain within acceptable tolerance for standard logic applications. 74HC03D,653 (NXP Semiconductors) maintains functional compatibility but lacks detailed electrical parameter documentation. NLV74HC03ADR2G (onsemi) is obsolete and should not be selected for new designs despite technical compatibility.

Frequently Asked Questions (FAQ)

Q: Can I substitute CD74HC03M with CD74HC03M96? A: Yes. Both parts are manufactured by Texas Instruments, share identical electrical specifications, and are packaged in 14-SOIC. The difference is packaging format: CD74HC03M is supplied in tube format, while CD74HC03M96 is supplied in tape & reel format. CD74HC03M96 is currently active, making it the preferred choice for ongoing procurement.

Q: Are onsemi MC74HC03ADR2G and MC74HC03ADG interchangeable with the CD74HC03M? A: Yes, with minor performance variance. Both onsemi parts maintain identical logic configuration, supply voltage range, operating temperature, and package type. Quiescent current is lower (1 µA vs. 2 µA), and propagation delay is slightly extended (20 ns vs. 17 ns at 6V, 50pF). These differences do not affect functional compatibility in standard logic applications. MC74HC03ADG is tube-packaged; MC74HC03ADR2G is cut tape & Digi-Reel packaged.

Q: What is the difference between tube and tape & reel packaging? A: Tube packaging is used for manual handling and lower-volume applications. Tape & reel and cut tape formats are designed for automated assembly processes and higher-volume production. Electrical performance is identical; packaging choice depends on assembly methodology and procurement volume.

Q: Why is NLV74HC03ADR2G listed if it is obsolete? A: NLV74HC03ADR2G is documented as an obsolete part for reference purposes. It should not be selected for new designs. Active alternatives from onsemi (MC74HC03ADR2G, MC74HC03ADG) provide equivalent functionality with current product support.

Q: Can I use 74HC03D,653 from NXP as a substitute? A: 74HC03D,653 maintains functional compatibility as a 4-channel, 2-input NAND gate in 14-SOIC packaging with active product status. However, detailed electrical parameters are not provided in available documentation. Verification with NXP datasheets is recommended before design implementation.

Q: What compliance certifications apply to these parts? A: All listed parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Moisture sensitivity level is 1 (unlimited) for all parts, indicating no special moisture handling requirements during storage or assembly.
