CD74HC30PWT NAND Gate IC Equivalent & Substitute Parts

Part Overview

The CD74HC30PWT is a single-channel 8-input NAND gate logic IC manufactured by Texas Instruments in 14-TSSOP surface mount packaging. This part is discontinued at DiGi Electronics, making equivalent substitutes necessary for ongoing production and maintenance applications. The 74HC30 logic family provides standard NAND gate functionality across multiple manufacturers, with several active alternatives available that maintain electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD74HC30PWT is determined by strict equivalence across the following parameters: logic type (NAND gate), circuit count (1 channel), input count (8 inputs), supply voltage range (2V to 6V), output current specifications (5.2 mA), input logic thresholds, package type (14-TSSOP), and mounting method (surface mount). All substitute parts listed maintain these core electrical and mechanical specifications. Differences in propagation delay, operating temperature range, and product status are noted but do not prevent functional substitution when application requirements permit.

Parameter Comparison

Engineering Selection Recommendations

CD74HC30PWR (Texas Instruments) is the primary direct replacement, maintaining identical electrical specifications and operating temperature range while offering active product status and higher inventory availability (19,432 units in stock). This part is recommended for applications requiring no design modification.

74HC30PW-Q100J (Nexperia USA Inc.) provides an automotive-qualified alternative with AEC-Q100 certification, suitable for automotive and high-reliability applications. Operating temperature range is narrower (-40°C to 125°C) compared to the original part. This part is active with 3,021 units available.

MC74HC30ADTR2G (onsemi) maintains the full operating temperature range (-55°C to 125°C) and is active with 3,610 units in stock. Propagation delay is specified at 30 ns versus 22 ns for the original part; this difference is acceptable for non-timing-critical applications.

74HC30PW,118 (NXP Semiconductors) is available in bulk packaging with 3,800 units in stock and active status. Detailed electrical specifications are not provided; verification against application requirements is necessary before selection.

All substitute parts maintain ROHS3 compliance, MSL rating of 1, and 14-TSSOP package compatibility.

Frequently Asked Questions (FAQ)

Q: Can CD74HC30PWR directly replace CD74HC30PWT without circuit modification? A: Yes. CD74HC30PWR is electrically and mechanically identical to CD74HC30PWT, with matching supply voltage range (2V to 6V), output current (5.2 mA), propagation delay (22 ns @ 6V, 50pF), and operating temperature range (-55°C to 125°C). Both use 14-TSSOP surface mount packaging. No design changes are required.

Q: What is the difference between the 22 ns and 30 ns propagation delay specifications? A: CD74HC30PWR and 74HC30PW-Q100J specify 22 ns maximum propagation delay at 6V with 50pF load, while MC74HC30ADTR2G specifies 30 ns under the same conditions. For applications with timing-critical signal paths, the 8 ns difference may be significant. For general logic applications, both specifications are acceptable.

Q: Is 74HC30PW-Q100J suitable for non-automotive applications? A: Yes. The AEC-Q100 automotive qualification of 74HC30PW-Q100J indicates enhanced reliability and testing; it is fully compatible with non-automotive applications. The narrower operating temperature range (-40°C to 125°C versus -55°C to 125°C) should be verified against application requirements.

Q: Why is 74HC30PW,118 listed without complete electrical specifications? A: 74HC30PW,118 is supplied in bulk packaging rather than tape and reel. Complete electrical specifications are available from NXP Semiconductors documentation; the base product number 74HC30 confirms functional equivalence to other listed parts.

Q: Are all substitute parts RoHS compliant? A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL rating of 1 (unlimited moisture sensitivity level), matching the original CD74HC30PWT specifications.

Q: Can I use these parts interchangeably in existing PCB designs? A: Yes, provided the PCB footprint accommodates 14-TSSOP surface mount packaging. All listed parts use identical package dimensions (0.173" width, 4.40mm). Verify tape and reel versus bulk packaging requirements for your procurement process.
