HEF4093BT,652 NAND Gate IC Equivalent & Substitute Parts

Part Overview

The HEF4093BT,652 is a 4-channel NAND gate IC with Schmitt trigger inputs manufactured by Nexperia USA Inc. in a 14-SOIC surface mount package. This part operates across a 3V to 15V supply voltage range and is classified as obsolete. Due to its obsolete status, equivalent and substitute parts from active manufacturers are necessary for new designs and ongoing production requirements. Substitute parts maintain the core logic function while offering improved availability and, in some cases, extended operating parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the HEF4093BT,652 is determined by the following criteria:

Core Functional Requirements:

• Logic Type: NAND Gate with 4 channels and 2 inputs per channel
• Schmitt Trigger feature presence
• Package compatibility: 14-SOIC form factor
• Surface mount mounting type

Electrical Parameter Compatibility:

• Supply voltage range must encompass or exceed 3V ~ 15V
• Quiescent current ≤ 1 µA (preferred) or up to 4 µA (acceptable for non-power-critical applications)
• Output current capability ≥ 3.4mA
• Input logic levels must be compatible with standard CMOS logic
• Propagation delay ≤ 130ns @ 15V, 50pF (acceptable variance from 60ns baseline)
• Operating temperature range must include -40°C ~ 125°C minimum

Compliance Requirements:

• ROHS3 compliance required
• MSL rating of 1 (Unlimited) preferred

Substitute parts are grouped into two categories: direct substitutes (identical electrical and packaging specifications) and parametric equivalents (compatible electrical performance with minor parameter variations).

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: HEF4093BT,653

The HEF4093BT,653 is the direct substitute for HEF4093BT,652. Both parts are manufactured by Nexperia USA Inc., share identical electrical specifications, and are packaged in 14-SOIC. The HEF4093BT,653 is active and maintains full compatibility with designs originally specified for the HEF4093BT,652. This part offers the shortest migration path with zero design changes required.

Secondary Recommendation: HEC4093BT,112

The HEC4093BT,112 manufactured by NXP USA Inc. is a parametric equivalent offering identical electrical performance to the original part. It maintains the same supply voltage range (3V ~ 15V), quiescent current (1 µA), output current (3.4mA), propagation delay (60ns), and operating temperature range (-40°C ~ 125°C). The HEC4093BT,112 is active and ROHS3 compliant.

Alternative Recommendations for Extended Operating Range:

The CD4093BQM96G4Q1 and CD4093BQM96Q1 from Texas Instruments are active parts with automotive-grade qualification (AEC-Q100). These parts extend the supply voltage range to 3V ~ 18V and lower operating temperature to -40°C. They maintain Schmitt trigger functionality and ROHS3 compliance. Propagation delay increases to 130ns, which is acceptable for non-time-critical applications.

Consideration for High Output Current Requirements:

The MC14093BDR2G and MC14093BDG from onsemi provide higher output current capability (8.8mA versus 3.4mA) and extended temperature range (-55°C ~ 125°C). These parts lack Schmitt trigger features but maintain the 4-channel NAND gate logic function. Selection depends on whether Schmitt trigger hysteresis is required in the application.

Parts to Avoid:

CD4093BMT is discontinued at DiGi Electronics and should not be selected for new designs despite remaining inventory availability.

Frequently Asked Questions (FAQ)

Q: Can HEF4093BT,653 directly replace HEF4093BT,652 without design changes?

A: Yes. The HEF4093BT,653 is electrically and mechanically identical to HEF4093BT,652. Both are 4-channel NAND gates with Schmitt triggers in 14-SOIC packages with matching electrical specifications. No PCB layout or schematic modifications are required.

Q: What is the difference between HEF4093BT,653 and HEC4093BT,112?

A: Both parts are parametric equivalents with identical electrical specifications. HEF4093BT,653 is manufactured by Nexperia USA Inc., while HEC4093BT,112 is manufactured by NXP USA Inc. Selection between these parts depends on supplier availability and procurement preferences.

Q: Why do some substitute parts have different propagation delays?

A: Propagation delay varies by manufacturer process technology. The CD4093 series from Texas Instruments and Harris Corporation exhibits 130ns propagation delay compared to 60ns for the HEF4093 and HEC4093 series. This difference is acceptable for applications where timing margins exceed 70ns. For time-critical applications, select parts with 60ns or 80ns propagation delay.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification. All parts also maintain MSL rating of 1 (Unlimited) moisture sensitivity level.

Q: What is the significance of Schmitt trigger functionality?

A: Schmitt trigger inputs provide hysteresis, improving noise immunity in applications with slow-rising or noisy input signals. The HEF4093BT,652 includes Schmitt triggers. Substitute parts from the CD4093 series and HEC4093 series maintain this feature. The MC14093 series from onsemi does not include Schmitt triggers; selection of these parts requires confirmation that hysteresis is not required in the application.

Q: Can MC14093BDR2G or MC14093BDG be used as direct replacements?

A: These parts are functional equivalents for the NAND gate logic operation but lack Schmitt trigger inputs. They are suitable only if the application does not depend on Schmitt trigger hysteresis. Both parts offer higher output current (8.8mA) and extended temperature range (-55°C ~ 125°C), making them suitable for high-current or wide-temperature applications.

Q: What is the difference between CD4093BQM96G4Q1 and CD4093BQM96Q1?

A: Both parts are automotive-grade (AEC-Q100 qualified) with identical electrical specifications. CD4093BQM96G4Q1 is available in Cut Tape & Digi-Reel packaging, while CD4093BQM96Q1 is supplied in Tape & Reel packaging. Selection depends on assembly process requirements.

Q: Is the extended supply voltage range (3V ~ 18V) of substitute parts beneficial?

A: Extended supply voltage range provides design flexibility for applications operating above 15V. However, if the original design operates within 3V ~ 15V, the extended range offers no functional advantage. Verify that circuit design does not depend on the 15V maximum limit before selecting parts with 18V maximum ratings.

Q: Can I use parts with different quiescent current specifications?

A: Yes, if power consumption is not a critical constraint. The HEF4093BT,652 specifies 1 µA maximum quiescent current. Substitute parts with 4 µA quiescent current (CD4093 series) are acceptable for applications where standby power consumption is not tightly controlled. For battery-powered or ultra-low-power applications, select parts with 1 µA quiescent current specification.
