CD4069UBMT Equivalent & Substitute Parts

Part Overview

The CD4069UBMT is a 6-channel inverter logic IC manufactured by Texas Instruments in 14-SOIC surface mount packaging. This part is discontinued at DiGi Electronics but remains available through inventory channels. The CD4069UBMT operates across a wide supply voltage range of 3V to 18V and is compliant with ROHS3 standards. Due to its discontinued status, equivalent and substitute parts from active manufacturers provide direct functional alternatives for new designs and production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD4069UBMT is determined by the following critical parameters that must remain constant or compatible:

• Logic Type: Inverter (6-channel, 1-input configuration)
• Voltage Supply Range: Minimum 3V to 18V support
• Input/Output Logic Levels: 1V ~ 2.5V (Low), 4V ~ 12.5V (High)
• Mounting Type: Surface Mount
• Package: 14-SOIC form factor
• Operating Temperature Range: -55°C to 125°C minimum
• RoHS3 Compliance: Required for regulatory alignment

Substitute parts are grouped into two categories:

Parametric Equivalents maintain identical electrical specifications and full parameter compatibility with the CD4069UBMT.

Direct Manufacturer Alternatives provide functional equivalence with minor variations in output current, propagation delay, or supply voltage range that remain within acceptable design tolerances for standard inverter applications.

Parameter Comparison

Engineering Selection Recommendations

CD4069UBM96 (Texas Instruments, Active) is the primary parametric equivalent. It maintains identical electrical specifications to the CD4069UBMT with full supply voltage range support (3V ~ 18V) and matching output current and propagation delay characteristics. This part is currently in active production status with substantial inventory availability.

MC14069UBDR2G and MC14069UBDG (onsemi, Active) provide functional alternatives with enhanced output current capability (8.8mA versus 3.4mA). Both support the full 3V ~ 18V supply range and maintain the -55°C to 125°C operating temperature specification. These parts are suitable for applications requiring higher output drive capability.

HEC4069UBT,112 and HEC4069UBT,118 (NXP USA Inc., Active) offer improved propagation delay performance (25ns versus 50ns) but operate within a reduced supply voltage range (3V ~ 15V) and narrower operating temperature range (-40°C to 125°C). These parts are appropriate for designs operating within these constraints.

HEF4069UBT,652 and HEF4069UBT,653 (NXP/Nexperia, Active) provide moderate propagation delay improvement (30ns) with the same output current as the original part. Supply voltage range is limited to 3V ~ 15V with operating temperature range of -40°C to 125°C.

HCF4069YUM013TR (STMicroelectronics, Active) is qualified to AEC-Q100 automotive standards and extends the supply voltage range to 3V ~ 20V. This part is suitable for automotive applications but operates within a narrower temperature range (-40°C to 125°C).

Frequently Asked Questions (FAQ)

Q: Can CD4069UBM96 be used as a direct replacement for CD4069UBMT?

A: Yes. CD4069UBM96 is a parametric equivalent with identical electrical specifications, supply voltage range, output current, and propagation delay. Both parts are 14-SOIC surface mount packages with matching pin configurations.

Q: What is the primary difference between onsemi MC14069 variants and the original CD4069UBMT?

A: The MC14069UBDR2G and MC14069UBDG provide higher output current (8.8mA versus 3.4mA) and slightly longer propagation delay (55ns versus 50ns). Both maintain the full 3V ~ 18V supply voltage range and -55°C to 125°C operating temperature specification.

Q: Are NXP HEC4069 and HEF4069 parts suitable for all CD4069UBMT applications?

A: NXP parts offer faster propagation delay but operate within a reduced supply voltage range (3V ~ 15V maximum) and narrower operating temperature range (-40°C to 125°C). Designs requiring the full 3V ~ 18V supply range or -55°C operation must use alternatives that support these specifications.

Q: What packaging options are available for CD4069 inverter ICs?

A: All listed substitute parts use 14-SOIC surface mount packaging with 0.154" width (3.90mm). Packaging variations exist in tape format (Cut Tape, Bulk, or Tube) but do not affect electrical compatibility or PCB assembly.

Q: Is the HCF4069YUM013TR suitable for non-automotive applications?

A: Yes. The HCF4069YUM013TR meets AEC-Q100 automotive qualification but functions as a standard inverter IC in any application. The automotive qualification provides additional quality assurance but does not restrict use in non-automotive designs. Note the reduced operating temperature range (-40°C to 125°C) and extended supply voltage range (3V ~ 20V).

Q: How do I select between multiple active substitute parts?

A: Selection depends on application requirements: (1) For maximum compatibility with the original CD4069UBMT specification, use CD4069UBM96; (2) For applications requiring higher output current, use MC14069UBDR2G or MC14069UBDG; (3) For designs operating within 3V ~ 15V supply range, NXP HEC4069 or HEF4069 parts offer faster propagation delay; (4) For automotive applications, use HCF4069YUM013TR.
