Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HEC4069UBT,112 is determined by the following criteria:

Core Functional Requirements:

• Logic Type: Inverter
• Number of Circuits: 6
• Number of Inputs: 1
• Series: 4000B or 4000 (compatible logic families)

Electrical Compatibility Parameters:

• Voltage - Supply: Must support minimum 3V to 15V range (higher maximum ratings are acceptable)
• Current - Quiescent (Max): Must not exceed 1 µA
• Current - Output High, Low: Must support minimum 3.4mA per channel
• Input Logic Level - Low: 1V ~ 2.5V
• Input Logic Level - High: 4V ~ 12.5V
• Max Propagation Delay: Must not exceed 25ns @ 15V, 50pF (lower delays are acceptable)
• Operating Temperature: Must support -40°C ~ 125°C minimum range

Mechanical & Compliance Requirements:

• Mounting Type: Surface Mount
• Package / Case: 14-SOIC or 14-SO (same physical footprint)
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Substitute parts meeting all these criteria are electrically and mechanically interchangeable with the HEC4069UBT,112 in standard applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Full Compatibility):

CD4069UBM and CD4069UBM96 from Texas Instruments are direct substitutes. Both parts maintain identical electrical specifications to the HEC4069UBT,112 with extended supply voltage range (3V ~ 18V) and wider operating temperature range (-55°C ~ 125°C). CD4069UBM96 offers significantly higher inventory availability (105,300 units) compared to the primary part. Both are ROHS3 compliant and MSL 1 rated.

Secondary Substitutes (Compatible with Minor Differences):

MC14069UBDR2G and MC14069UBDG from onsemi are functionally compatible. These parts feature higher output current capability (8.8mA vs. 3.4mA) and slightly longer propagation delay (55ns vs. 25ns). The extended supply voltage range (3V ~ 18V) and wider operating temperature (-55°C ~ 125°C) provide additional design margin. MC14069UBDR2G has the highest inventory availability (142,600 units) among all substitutes. Both are ROHS3 compliant and MSL 1 rated.

Specialized Substitute (Automotive Grade):

HCF4069YUM013TR from STMicroelectronics is an automotive-qualified alternative (AEC-Q100) suitable for applications requiring automotive-grade components. This part features higher output current (6.8mA) and quiescent current (5 µA), with extended supply voltage range (3V ~ 20V). Operating temperature range matches the primary part (-40°C ~ 125°C). ROHS3 compliant and MSL 1 rated.

Discontinued Part:

CD4069UBMT from Texas Instruments is discontinued at DiGi Electronics and should not be selected for new designs despite technical compatibility.

Package Consideration:

CD4069UBNSR uses a wider 14-SO package (0.209", 5.30mm width) compared to the standard 14-SOIC (0.154", 3.90mm width) used by the primary part and most substitutes. This part is not recommended for designs with standard 14-SOIC footprints.

Frequently Asked Questions (FAQ)

Q: Can I use CD4069UBM96 as a direct replacement for HEC4069UBT,112?

A: Yes. CD4069UBM96 meets all electrical and mechanical requirements. The extended supply voltage range (3V ~ 18V vs. 3V ~ 15V) and wider operating temperature (-55°C ~ 125°C vs. -40°C ~ 125°C) provide additional design margin. Both use identical 14-SOIC packaging and are ROHS3 compliant.

Q: What is the difference between MC14069UBDR2G and CD4069UBM?

A: Both are functionally compatible substitutes. MC14069UBDR2G has higher output current (8.8mA vs. 3.4mA) and slightly longer propagation delay (55ns vs. 50ns). MC14069UBDR2G offers significantly higher inventory availability. Selection depends on output current requirements and design timing margins.

Q: Why does CD4069UBNSR have a different package size?

A: CD4069UBNSR uses a 14-SO package with 0.209" width versus the standard 14-SOIC with 0.154" width. This wider package is not compatible with standard 14-SOIC PCB footprints. Use this part only if your design specifically accommodates the wider package.

Q: Is HCF4069YUM013TR suitable for automotive applications?

A: Yes. HCF4069YUM013TR carries AEC-Q100 automotive qualification and is designed for automotive-grade applications. It meets all electrical requirements of the primary part with higher output current capability (6.8mA). Use this part when automotive-grade components are specified.

Q: Can I use MC14069UBDG instead of MC14069UBDR2G?

A: Yes. Both onsemi parts are electrically identical with the same output current (8.8mA) and propagation delay (55ns). The difference is packaging format: MC14069UBDG is supplied in Tube packaging while MC14069UBDR2G is supplied in Cut Tape (CT) & Digi-Reel format. Selection depends on your assembly process requirements.

Q: What happens if I operate a substitute part at 18V when my design uses 15V?

A: All recommended substitutes support 18V supply voltage. Operating at 15V is well within the specified range and presents no compatibility issues. The extended voltage rating provides design flexibility without affecting performance at your operating point.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the primary part's compliance status.
