Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD4093BMG4 is determined by the following criteria:

Core Functional Requirements:

• Logic Type: NAND Gate
• Number of Circuits: 4 channels
• Number of Inputs: 2 inputs per channel
• Package / Case: 14-SOIC form factor
• Mounting Type: Surface Mount

Electrical Compatibility Range:

• Voltage - Supply: Minimum 3V to 15V overlap required
• Operating Temperature: Minimum -40°C to 125°C overlap required

Compliance Requirements:

• RoHS3 Compliant
• REACH Unaffected status

Substitute parts are grouped into two categories based on feature set: Schmitt Trigger variants (NXP HEC4093BT,118; Nexperia HEF4093BT,653 and HEF4093BT-Q100,118) and standard NAND gate variants (onsemi MC14093BDR2G and MC14093BDG). All listed substitutes meet the core functional and compliance requirements.

Parameter Comparison

Engineering Selection Recommendations

For Schmitt Trigger Feature Requirement:

If the Schmitt Trigger input characteristic is functionally required, select from the following active alternatives:

• HEF4093BT,653 (Nexperia) or HEF4093BT-Q100,118 (Nexperia): Both maintain Schmitt Trigger functionality with improved propagation delay (60ns vs. 130ns). The HEF4093BT-Q100,118 variant includes AEC-Q100 automotive qualification. Operating temperature range is -40°C to 125°C, which is narrower than the original part but covers standard industrial and automotive applications.

• HEC4093BT,118 (NXP): Provides Schmitt Trigger functionality with 60ns propagation delay and -40°C to 125°C operating range. Suitable for applications not requiring extended low-temperature operation below -40°C.

For Standard NAND Gate Functionality Without Schmitt Trigger Requirement:

• MC14093BDR2G (onsemi) or MC14093BDG (onsemi): Both provide 4-channel NAND gate functionality with extended supply voltage range (3V ~ 18V) and operating temperature range (-55°C ~ 125°C) matching the original part. These variants offer improved quiescent current (1 µA vs. 4 µA) and faster propagation delay (80ns vs. 130ns). MC14093BDR2G is supplied in Cut Tape & Digi-Reel packaging; MC14093BDG is supplied in Tube packaging.

Compliance Verification:

All substitute parts are ROHS3 Compliant and REACH Unaffected, maintaining regulatory compliance with the original CD4093BMG4.

Frequently Asked Questions (FAQ)

Q: Can I use MC14093BDR2G or MC14093BDG as a direct replacement if my circuit does not require Schmitt Trigger functionality?

A: Yes. Both onsemi variants provide identical 4-channel, 2-input NAND gate functionality in the same 14-SOIC package. They offer superior performance characteristics including lower quiescent current (1 µA vs. 4 µA) and faster propagation delay (80ns vs. 130ns). If your circuit design does not depend on Schmitt Trigger hysteresis, these parts are functionally compatible.

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

A: Both are Nexperia Schmitt Trigger NAND gate ICs with identical electrical specifications. The HEF4093BT-Q100,118 includes AEC-Q100 automotive qualification and is supplied in Tape & Reel packaging, making it suitable for automotive applications. The HEF4093BT,653 is supplied in Cut Tape & Digi-Reel packaging for general industrial use.

Q: Why do some substitutes have a narrower operating temperature range (-40°C to 125°C vs. -55°C to 125°C)?

A: The NXP and Nexperia variants (HEC4093BT,118 and HEF4093BT series) are specified for -40°C minimum operating temperature, while Texas Instruments and onsemi variants extend to -55°C. Select based on your application's minimum operating temperature requirement. For applications operating above -40°C, the NXP and Nexperia variants are fully compatible.

Q: Are all substitute parts available in the same package?

A: Yes. All substitute parts use the 14-SOIC (0.154", 3.90mm Width) surface mount package, ensuring PCB layout and footprint compatibility with the original CD4093BMG4.

Q: What is the inventory status of these substitutes?

A: All listed substitutes are currently active products with substantial inventory: MC14093BDR2G (105,200 pcs), HEC4093BT,118 (1,088 pcs), HEF4093BT,653 (2,256 pcs), HEF4093BT-Q100,118 (12,158 pcs), and MC14093BDG (9,255 pcs).
