CD4093BM NAND Gate IC Equivalent & Substitute Parts

Part Overview

The CD4093BM is a 4-channel NAND gate IC with Schmitt trigger inputs manufactured by Texas Instruments in a 14-SOIC surface mount package. This logic component operates across a wide supply voltage range of 3V to 18V and is designed for digital signal processing applications requiring noise immunity through Schmitt trigger functionality. The part is currently in active production status with 1,244 units in stock. Substitute parts are necessary to address supply chain flexibility, alternative packaging preferences, or specific performance requirements while maintaining functional compatibility within the 4000B logic series.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD4093BM is determined by the following critical parameters:

Core Functional Requirements:

• Logic Type: NAND Gate (4-channel, 2-input configuration)
• Series: 4000B logic family
• Package: 14-SOIC form factor
• Mounting Type: Surface Mount

Electrical Compatibility Range:

• Supply Voltage: 3V to 18V minimum (parts with 3V ~ 15V are compatible within the CD4093BM's operating envelope)
• Operating Temperature: -55°C to 125°C (parts with -40°C to 125°C are compatible for most applications)

Compliance Requirements:

• RoHS3 Compliant
• MSL Level 1 (Unlimited moisture sensitivity)

All substitute parts listed maintain these core parameters. Performance variations in propagation delay, quiescent current, and output drive capability are secondary considerations that do not prevent functional substitution within the 4000B series architecture.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active production status and ROHS3 compliance, ensuring long-term availability and regulatory alignment with the CD4093BM.

For applications requiring extended temperature range (-55°C operation): Select CD4093BM, MC14093BDR2G, or MC14093BDG. These parts support the full -55°C to 125°C range, whereas NXP and Nexperia variants operate from -40°C minimum.

For applications requiring maximum supply voltage tolerance (18V): Select CD4093BM, MC14093BDR2G, or MC14093BDG. These parts are rated for 3V to 18V, whereas NXP and Nexperia variants are limited to 3V to 15V.

For Schmitt trigger feature requirement: Select CD4093BM, HEC4093BT,118, HEF4093BT,653, or HEF4093BT-Q100,118. These parts explicitly include Schmitt trigger functionality. MC14093BDR2G and MC14093BDG do not specify this feature.

For automotive-grade applications: Select HEF4093BT-Q100,118, which carries AEC-Q100 qualification and Automotive grade designation.

For packaging flexibility: CD4093BM and MC14093BDG are available in Tube packaging. MC14093BDR2G is available in Cut Tape & Digi-Reel. HEC4093BT,118, HEF4093BT,653, and HEF4093BT-Q100,118 are available in Cut Tape & Digi-Reel or Tape & Reel formats.

Frequently Asked Questions (FAQ)

Q: Can I substitute MC14093BDR2G for CD4093BM in all applications?

A: MC14093BDR2G is functionally compatible for most applications. However, it does not specify Schmitt trigger features and has higher output drive capability (8.8mA vs 3.4mA). If your circuit design depends on Schmitt trigger hysteresis or specific output impedance characteristics, use HEF4093BT,653 or HEC4093BT,118 instead.

Q: What is the difference between HEF4093BT,653 and HEF4093BT-Q100,118?

A: Both parts are electrically identical with the same electrical specifications. HEF4093BT-Q100,118 carries AEC-Q100 automotive qualification and is designated as Automotive grade, making it suitable for automotive applications. HEF4093BT,653 is the standard industrial variant.

Q: Are there temperature range limitations I should consider?

A: Yes. CD4093BM, MC14093BDR2G, and MC14093BDG support -55°C to 125°C operation. HEC4093BT,118, HEF4093BT,653, and HEF4093BT-Q100,118 support -40°C to 125°C. If your application requires operation below -40°C, use only the Texas Instruments or onsemi variants.

Q: Can I use these parts interchangeably in a 18V supply circuit?

A: No. NXP and Nexperia parts are rated for maximum 15V supply. For 18V operation, use only CD4093BM, MC14093BDR2G, or MC14093BDG.

Q: What packaging options are available?

A: CD4093BM is supplied in Tube. MC14093BDR2G is supplied in Cut Tape & Digi-Reel. MC14093BDG is supplied in Tube. HEC4093BT,118 packaging is not specified. HEF4093BT,653 is supplied in Cut Tape & Digi-Reel. HEF4093BT-Q100,118 is supplied in Tape & Reel.

Q: Do all parts have the same propagation delay?

A: No. CD4093BM has 130ns propagation delay at 15V with 50pF load. MC14093BDR2G and MC14093BDG have 80ns. HEC4093BT,118, HEF4093BT,653, and HEF4093BT-Q100,118 have 60ns. Faster propagation delay may affect circuit timing in high-speed applications.

Q: Are all parts RoHS compliant?

A: Yes. All listed parts are ROHS3 compliant with MSL Level 1 (Unlimited moisture sensitivity), ensuring compatibility with modern manufacturing and environmental regulations.
