MC14050BDTG Equivalent & Substitute Parts

Part Overview

The MC14050BDTG is a non-inverting buffer IC from onsemi's 4000B logic series, featuring 6 elements with 1 bit per element and push-pull output configuration. This component operates across a wide supply voltage range of 3V to 18V and is housed in a 16-TSSOP surface mount package. The part is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MC14050BDTG is determined by the following critical parameters:

• Logic Type: Buffer, Non-Inverting
• Number of Elements: 6
• Number of Bits per Element: 1
• Output Type: Push-Pull
• Package / Case: 16-TSSOP (0.173", 4.40mm Width)
• Voltage - Supply: 3V ~ 18V
• Operating Temperature: -55°C ~ 125°C (TA)

The identified substitute parts CD4050BPW and CD4050BPWR from Texas Instruments satisfy all critical functional and mechanical parameters. Both parts maintain identical logic configuration, element count, output characteristics, supply voltage range, and operating temperature specifications. The 16-TSSOP package ensures mechanical and electrical compatibility with existing PCB designs.

Parameter Comparison

Engineering Selection Recommendations

CD4050BPWR is the primary substitute for new designs and production. This part maintains active product status with substantial inventory availability (21,392 pcs), ensuring supply chain continuity. All three parts are ROHS3 compliant and carry identical MSL ratings, meeting environmental and regulatory requirements.

CD4050BPW serves as a secondary alternative, though it carries discontinued status at DiGi Electronics. This part remains functionally equivalent but may present supply constraints for future procurement.

Output current specifications differ between the main part and substitutes: the MC14050BDTG provides 10mA high and 40mA low, while both Texas Instruments alternatives deliver 8mA high and 48mA low. These variations remain within typical application tolerances for 4000B series buffer circuits operating across the 3V to 18V supply range.

Frequently Asked Questions (FAQ)

Q: Can CD4050BPWR directly replace MC14050BDTG in existing designs?

A: Yes. Both parts share identical logic configuration, element count, output type, package, supply voltage range, and operating temperature specifications. The 16-TSSOP package ensures pin-for-pin compatibility and mechanical fit on existing PCBs.

Q: What is the significance of the output current differences?

A: The MC14050BDTG specifies 10mA high and 40mA low output current, while CD4050BPW and CD4050BPWR specify 8mA high and 48mA low. These variations reflect manufacturing differences between onsemi and Texas Instruments but do not affect functional compatibility in standard 4000B series buffer applications.

Q: Why is CD4050BPWR recommended over CD4050BPW?

A: CD4050BPWR maintains active product status with high inventory availability, providing superior supply chain reliability. CD4050BPW is discontinued at DiGi Electronics, presenting potential procurement challenges.

Q: Are all three parts RoHS compliant?

A: Yes. MC14050BDTG, CD4050BPW, and CD4050BPWR are all ROHS3 compliant with MSL rating of 1 (Unlimited), meeting environmental and regulatory standards.

Q: What packaging options are available for these substitutes?

A: MC14050BDTG is supplied in standard packaging. CD4050BPW is available in Tube packaging. CD4050BPWR is available in Cut Tape (CT) and Digi-Reel® packaging. All three use the 16-TSSOP package format.
