Substitute parts are grouped into three categories based on their relationship to the main part:

Parametric Equivalent (Same Manufacturer): CD4011UBM96 from Texas Instruments differs only in packaging format (Tape & Reel vs. Cut Tape) while maintaining identical electrical specifications and active product status.

Direct Manufacturer Alternatives (onsemi): MC14011UBDR2G, MC14011BDR2G, MC14011UBDG, MC14011BDG, NLV14011BDR2G, NLV14011UBDR2G, and NLV14011BDG provide functional equivalence with the same logic configuration and package. Minor variations exist in output current specifications and propagation delay characteristics.

MFR Recommended Alternatives (Nexperia): HEF4011BT,653 and HEF4011BT-Q100J from Nexperia USA Inc. provide functional equivalence with tighter input logic level specifications and faster propagation delay (35ns vs. 50ns). The HEF4011BT-Q100J variant includes AEC-Q100 automotive qualification.

Engineering Selection Recommendations

For Direct Replacement with Active Status: CD4011UBM96 from Texas Instruments is the primary equivalent, offering identical electrical specifications and active production status. The only difference is packaging format (Tape & Reel instead of Cut Tape), which does not affect functional performance.

For Extended Supply Voltage Range: onsemi alternatives (MC14011UBDR2G, MC14011BDR2G, MC14011UBDG, MC14011BDG, NLV14011BDR2G, NLV14011UBDR2G) maintain the full 3V to 18V supply range and are in active production. These parts are suitable for applications requiring the extended upper voltage limit beyond 15V.

For Improved Propagation Delay Performance: HEF4011BT,653 and HEF4011BT-Q100J from Nexperia offer faster propagation delay (35ns vs. 50ns) and are in active production. Note that these parts limit supply voltage to 3V to 15V, which may restrict use in applications requiring higher supply voltages. The HEF4011BT-Q100J variant includes AEC-Q100 automotive qualification for applications requiring automotive-grade components.

Parts to Avoid: NLV14011BDG is marked as Obsolete and should not be selected for new designs despite available inventory.

Frequently Asked Questions (FAQ)

Q: Can I use HEF4011BT,653 as a direct replacement for CD4011UBMT?

A: HEF4011BT,653 is functionally equivalent for logic operation and package type. However, it limits supply voltage to 3V–15V compared to the CD4011UBMT's 3V–18V range. If your application operates above 15V, this part is not suitable. For applications within the 3V–15V range, HEF4011BT,653 offers superior propagation delay performance (35ns vs. 50ns).

Q: What is the difference between MC14011UBDR2G and MC14011BDR2G?

A: Both are onsemi NAND gate ICs in 14-SOIC packages with identical supply voltage and operating temperature ranges. The primary difference is output current specification: MC14011UBDR2G provides 4.6mA high and 8.8mA low, while MC14011BDR2G provides 8.8mA for both high and low outputs. Select based on your circuit's output current requirements.

Q: Why does CD4011UBMT show Last Time Buy status?

A: Last Time Buy status indicates the manufacturer is discontinuing production. CD4011UBM96 from the same manufacturer (Texas Instruments) is the recommended active alternative with identical specifications.

Q: Can I use parts with different propagation delays interchangeably?

A: Propagation delay differences (35ns for Nexperia vs. 50ns–80ns for other manufacturers) may affect timing-critical applications. Verify that your circuit's timing margins accommodate the substitute part's propagation delay before selection.

Q: Is the 14-SOIC package identical across all substitute parts?

A: Yes. All substitute parts use the 14-SOIC (0.154", 3.90mm Width) package, ensuring mechanical and electrical compatibility on the PCB. Packaging format differences (Cut Tape, Tape & Reel, Tube) affect only handling and delivery, not board-level compatibility.

Q: Which substitute part has the highest inventory availability?

A: MC14011BDR2G from onsemi has the highest inventory at 17,500 pieces. HEF4011BT,653 from Nexperia has 11,960 pieces available. Both are in active production status.
