Supply Chain & Allocation Reality:

The CD4011B is the quad 2-input NAND of the 4000B CMOS generation - the logic of old industrial timers, alarm panels, appliance controls and instrument interlocks that are still in service and still repaired. Inside the 4000B family the pinout is a JEDEC standard, so every manufacturer copy swaps pin-for-pin. Outside the family it is a trap zone: the 74HC00 quad NAND looks like the same function in the same 14-pin body, and it is wired differently, runs on a narrower supply, and drives ten times the current.

3V to 15V; quiescent current nanoamp class; inputs protected to the rails.

Compatibility & Drop-In Notes: The correct substitution when a 4000B board needs a logic gate. No circuit change: same thresholds, same drive, same speed class for the application.

The Classical Second Source

Shenzhen Spot Stock (24-48h Dispatch)

Electrical & Core Specs:

The Motorola-line 4000B NAND - the part many of these boards were originally built around. Same pinout, same 3V to 15V window.

3V to 15V, standard 4000B drive (about 0.5mA at 5V rising to 3.4mA at 15V).

Compatibility & Drop-In Notes: Equivalent to the CD4011B in every circuit parameter that matters for legacy repair. The B suffix indicates buffered outputs - keep the B when replacing a B, and note the UB (unbuffered) variants are different parts.
Package & Solder Footprint: Standard 4000B 14-pin arrangement; TAB markings differ, pin geometry does not.

Same Socket, Schmitt Inputs

Shenzhen Spot Stock (24-48h Dispatch)

Electrical & Core Specs:

Same quad 2-input NAND function in the same 4000B pin arrangement, with Schmitt-trigger inputs: each input has defined hysteresis thresholds instead of a single transition point.

3V to 15V, same drive class as the 4011B.

Compatibility & Drop-In Notes: Pin-for-pin with the 4011B, but not behavior-for-behavior: in oscillator and timing circuits tuned around the plain 4011 thresholds, the Schmitt thresholds shift the frequency. In debounce and slow-edge duties it is strictly better. Check which role the gate plays before swapping.
Package & Solder Footprint: Identical 14-pin arrangement (the 4093 shares the 4011 pinout); same DIP/SOIC land patterns.
Shenzhen Warehouse Stock & MOQ: Stocked alongside the 4011 family; commonly bought together for repair kits.

Faster and Stronger - But a Different Wiring

Shenzhen Spot Stock (24-48h Dispatch)

Electrical & Core Specs:

The high-speed CMOS quad NAND: 2V to 6V supply, roughly 15ns propagation against 60-90ns for the 4000B part, and about +/-4mA output drive at 4.5V against 0.5mA for the 4011B at 5V.

2V to 6V only - it will not survive the 12V or 15V rails that legacy 4000B boards routinely run.

Compatibility & Drop-In Notes: Listed as the classic cross-family trap: same function, same package, different wiring and different voltage. It is the right modernization when a board is being redesigned for 5V - and the wrong part to press into a 12V legacy socket.
Package & Solder Footprint: A 74HC00 inserted into a CD4011B socket connects inputs to outputs at several pins. Never a straight swap.
Shenzhen Warehouse Stock & MOQ: Universal stock; the correct part when the redesign window exists.

Buyer & Quality Checklist for Sourcing Alternatives
  • Within the 4000B series the pinout is a JEDEC standard - CD4011B, HEF4011B, MC14011B and TC4011BP swap pin-for-pin. Across families (74HC00, 74LS00) nothing but the supply pins stays put.
  • The 4011B drive is small and symmetric: about 0.5mA at 5V, 1.3mA at 10V, 3.4mA at 15V. It drives CMOS inputs happily and LEDs or relays only through a transistor - do not expect HC-class drive.
  • Keep the suffix honest: B parts are buffered, UB parts are unbuffered; they differ in output curves and are not interchangeable in analog-adjacent positions.
  • The 4093 (Schmitt NAND) shares the pinout and improves slow-edge and debounce circuits, but changes oscillator timing. Identify the role of each gate before making the swap a policy.
  • Legacy boards often run the logic at 12V or 15V; check the rail before proposing any 74HC-family modernization - HC parts end at 6V.
  • For repairs, unmarked or re-marked 4011 stock is common; the part is cheap enough that verified lots from documented fabs are the sensible default.
Frequently Asked Technical Questions

Q: Can I replace a CD4011 with a 74HC00?

A: No - same function and package, different wiring. Only VDD (14) and VSS (7) share positions; the gate inputs and outputs are rearranged (pin 4 is an output on the 4011 and an input on the 74HC00), and the HC part only tolerates 6V. It is a redesign part, not a substitution.

Q: Is CD4093 a drop-in replacement for CD4011?

A: Pin-for-pin yes, behavior-for-behavior only sometimes: the 4093 adds Schmitt hysteresis. Great for switch debounce and slow edges; it shifts frequency in oscillators tuned around the plain 4011 thresholds.

Q: Why does the CD4011B only source half a milliamp at 5V?

A: That is the 4000B design point: micropower logic meant to run from 3V to 15V with nanoamp quiescent current. Drive grows with supply (about 3.4mA at 15V). Loads beyond that go through a transistor, as the original designer intended.

Technical details

Active production, through-hole CMOS NAND gate

Packaged in a 14-pin DIP (0.300", 7.62mm) for through-hole mounting, it is a direct fit for breadboard prototyping, legacy system repairs, or new designs that require the wide supply tolerance and low static power of the 4000B family.

The 3V to 18V supply range is the defining feature of the 4000B series. It allows the CD4011BE to interface directly with 5V TTL, 12V industrial rails, or 3.3V battery systems without a level translator. The input logic thresholds scale with VDD: low-level thresholds run from 1.5V to 4V, and high-level thresholds from 3.5V to 11V, ensuring consistent noise margins across the supply range.

The 125°C upper limit covers under-hood automotive applications, though note this part is not AEC-Q100 qualified — for automotive-grade CMOS NAND gates, look to the CD74HC or CD74HCT series with AEC-Q certification.

Through-hole 14-DIP: prototyping and rework friendly

The 14-DIP (0.300", 7.62mm) package with 0.1" pin spacing is the standard through-hole footprint. It is ideal for hand-assembled prototypes, socketed test boards, or field repairs where a surface-mount part would be impractical. The through-hole body also tolerates multiple soldering/desoldering cycles better than a fine-pitch SMD package, making it a good choice for development iterations or legacy system maintenance.

Propagation delay: 90 ns at 15V, 50 pF

Maximum propagation delay is 90 ns with a 15V supply and 50 pF load. This is slower than 74HC or 74HCT family gates (typically 10–30 ns), so the CD4011BE is not a fit for high-speed clock distribution or fast data paths. It is well suited for control logic, debounce circuits, oscillator gates, or any application where the signal rate stays below a few megahertz and the wide supply range or low quiescent current is the priority.

Output drive: 3.4 mA source and sink

This is sufficient to drive a single TTL load, an LED with a series resistor, or the input of another CMOS gate. For heavier loads — relays, high-current LEDs, or long cables — buffer the output with a transistor or a dedicated driver IC. The symmetrical drive simplifies interface design: the same resistor value works for both high and low states.

For dual-sourcing or supply-chain resilience, the 4000B series includes functionally similar NAND gates such as the CD4011B in other package variants, but the CD4011BE is the through-hole DIP version.
