CD4069UBPW Equivalent & Substitute Parts

Part Overview

The CD4069UBPW is a 6-channel inverter logic IC manufactured by Texas Instruments in the 4000B series. This part is discontinued at DiGi Electronics but remains available through inventory channels. The CD4069UBPW operates across a wide supply voltage range of 3V to 18V and is housed in a 14-TSSOP surface mount package. Due to its discontinued status, equivalent substitute parts from active manufacturers are necessary for new designs and ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD4069UBPW is determined by the following critical parameters:

• Logic Configuration: 6-channel inverter with single input per channel
• Package Type: 14-TSSOP surface mount package with identical physical dimensions
• Supply Voltage Range: Minimum 3V to 18V operation capability
• Quiescent Current: Maximum 1 µA specification
• Output Current Capability: Minimum 3.4mA output drive
• Input Logic Levels: Compatibility with 1V ~ 2.5V low and 4V ~ 12.5V high thresholds
• Operating Temperature Range: Support for -55°C to 125°C minimum
• Compliance: ROHS3 compliance and MSL Level 1 rating

Substitute parts must maintain compatibility across all these parameters. Variations in propagation delay, output current specifications, or temperature range limits may affect performance in timing-critical or extended-temperature applications.

Parameter Comparison

Engineering Selection Recommendations

CD4069UBPWR (Texas Instruments) is the direct equivalent with identical electrical specifications and active product status. This part maintains the same supply voltage range (3V ~ 18V), output current (3.4mA), and propagation delay (50ns @ 15V, 50pF) as the CD4069UBPW. The primary difference is packaging format (Cut Tape & Digi-Reel versus Tube), making it suitable for production environments requiring reel-based component delivery.

MC14069UBDTR2G (onsemi) and NLV14069UBDTR2G (onsemi) provide functional equivalence with enhanced output current capability (8.8mA versus 3.4mA). Both maintain the full supply voltage range and operating temperature specifications. The increased output current may benefit applications requiring higher drive capability. Propagation delay is slightly increased to 55ns at 15V, 50pF.

HEF4069UBTT,118 (Nexperia USA Inc.) offers the fastest propagation delay at 30ns @ 15V, 50pF, beneficial for timing-critical applications. However, this part has a reduced supply voltage maximum of 15V (versus 18V) and a narrower operating temperature range (-40°C to 125°C versus -55°C to 125°C). Selection of this part requires confirmation that application requirements do not exceed 15V supply or operate below -40°C.

All substitute parts maintain ROHS3 compliance and MSL Level 1 rating, ensuring compatibility with standard manufacturing and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can CD4069UBPWR be used as a direct replacement for CD4069UBPW?

A: Yes. CD4069UBPWR is electrically and functionally identical to CD4069UBPW. Both are Texas Instruments 6-channel inverter ICs in 14-TSSOP packages with identical electrical specifications. The difference is packaging format: CD4069UBPW is supplied in Tube packaging, while CD4069UBPWR is supplied in Cut Tape & Digi-Reel format.

Q: What is the difference between the onsemi parts (MC14069UBDTR2G and NLV14069UBDTR2G)?

A: Both onsemi parts are functionally equivalent 6-channel inverters with identical electrical specifications except for output current. MC14069UBDTR2G is supplied in Cut Tape & Digi-Reel format, while NLV14069UBDTR2G is supplied in Tape & Reel format. Both provide 8.8mA output current, which is higher than the original CD4069UBPW specification of 3.4mA.

Q: Can HEF4069UBTT,118 be used in all applications where CD4069UBPW is specified?

A: HEF4069UBTT,118 is functionally compatible for most applications but has two limitations: maximum supply voltage is 15V (versus 18V for CD4069UBPW) and minimum operating temperature is -40°C (versus -55°C for CD4069UBPW). Applications requiring supply voltages above 15V or operation below -40°C must use alternative substitutes.

Q: Are all substitute parts available in the same 14-TSSOP package?

A: Yes. All substitute parts listed are housed in 14-TSSOP surface mount packages with identical physical dimensions (0.173", 4.40mm Width), ensuring direct PCB compatibility without layout modifications.

Q: What is the significance of the propagation delay differences between substitutes?

A: Propagation delay determines the time required for a logic state change at the input to appear at the output. CD4069UBPW and CD4069UBPWR specify 50ns, MC14069UBDTR2G and NLV14069UBDTR2G specify 55ns, and HEF4069UBTT,118 specifies 30ns. Applications with strict timing requirements must account for these differences. The faster HEF4069UBTT,118 may improve performance in timing-critical circuits, while the slightly slower onsemi parts remain within acceptable tolerances for most standard logic applications.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. All substitute parts are ROHS3 compliant and rated MSL Level 1 (Unlimited moisture sensitivity), matching the compliance profile of the original CD4069UBPW. All parts carry EAR99 ECCN classification and REACH Unaffected status.
