CD4050BPW Equivalent & Substitute Parts

Part Overview

The CD4050BPW is a non-inverting buffer logic integrated circuit manufactured by Texas Instruments, designed for applications requiring signal buffering across a wide supply voltage range of 3V to 18V. This 16-TSSOP surface mount device provides 6 independent buffer elements with push-pull outputs, each capable of handling 1 bit per element. The CD4050BPW is currently discontinued at DiGi Electronics, making equivalent substitute parts necessary for ongoing production and maintenance applications. Substitute parts must maintain identical electrical characteristics and package specifications to ensure direct compatibility in existing designs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CD4050BPW are qualified based on the following critical parameters that determine functional and mechanical compatibility:

Electrical Compatibility Criteria:

• Logic Type: Buffer, Non-Inverting (must be identical)
• Number of Elements: 6 (must be identical)
• Number of Bits per Element: 1 (must be identical)
• Output Type: Push-Pull (must be identical)
• Voltage - Supply: 3V ~ 18V (must be identical or broader range)
• Operating Temperature: -55°C ~ 125°C (TA) (must be identical or broader range)

Mechanical Compatibility Criteria:

• Package / Case: 16-TSSOP (0.173", 4.40mm Width) (must be identical)
• Mounting Type: Surface Mount (must be identical)

Compliance Criteria:

• RoHS Status: ROHS3 Compliant (must be maintained)
• Moisture Sensitivity Level (MSL): 1 (Unlimited) (must be identical or lower sensitivity)

The CD4050BPWR from Texas Instruments and MC14050BDTR2G from onsemi meet all electrical, mechanical, and compliance requirements. The MC14050BDTG from onsemi also meets these requirements but carries an Obsolete product status.

Parameter Comparison

Engineering Selection Recommendations

CD4050BPWR (Texas Instruments) is the primary substitute for CD4050BPW. Both parts are manufactured by Texas Instruments, share identical electrical specifications including output current ratings of 8mA and 48mA, and maintain the same 4000B series designation. The CD4050BPWR carries Active product status with significantly higher inventory availability (21392 units), ensuring supply chain continuity. Both parts are ROHS3 compliant with MSL 1 rating. The difference in packaging (Cut Tape & Digi-Reel® versus Tube) does not affect electrical or mechanical compatibility.

MC14050BDTR2G (onsemi) is a secondary substitute manufactured by onsemi. This part maintains all critical electrical and mechanical parameters including the 16-TSSOP package, 3V to 18V supply voltage range, and -55°C to 125°C operating temperature. The output current specifications differ slightly (10mA high, 40mA low versus 8mA high, 48mA low), remaining within acceptable buffer circuit tolerances. MC14050BDTR2G carries Active product status with 2426 units in inventory and is ROHS3 compliant with MSL 1 rating.

MC14050BDTG (onsemi) meets all electrical and mechanical compatibility requirements but carries Obsolete product status. This part should be considered only when CD4050BPWR and MC14050BDTR2G are unavailable, as obsolete status indicates discontinued manufacturing and limited future availability.

Frequently Asked Questions (FAQ)

Q: Can CD4050BPWR be used as a direct replacement for CD4050BPW?

A: Yes. CD4050BPWR is a direct substitute for CD4050BPW. Both parts are manufactured by Texas Instruments, share identical electrical specifications (8mA/48mA output current, 3V-18V supply voltage, -55°C to 125°C operating temperature), and use the same 16-TSSOP package. The only difference is packaging format (Cut Tape & Digi-Reel® versus Tube), which does not affect circuit functionality or PCB assembly compatibility.

Q: What are the differences between Texas Instruments and onsemi versions?

A: The primary difference is output current specification. Texas Instruments CD4050BPWR provides 8mA high and 48mA low output current, while onsemi MC14050BDTR2G provides 10mA high and 40mA low output current. Both specifications support standard buffer applications. All other parameters including supply voltage range, operating temperature, package type, and compliance certifications are identical.

Q: Is MC14050BDTG suitable for new designs?

A: MC14050BDTG carries Obsolete product status and should not be selected for new designs. Use CD4050BPWR or MC14050BDTR2G instead, both of which have Active status and confirmed long-term availability.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. CD4050BPWR, MC14050BDTR2G, and MC14050BDTG are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level, matching the original CD4050BPW specifications.

Q: Does packaging format affect PCB assembly?

A: Packaging format (Tube, Cut Tape & Digi-Reel®, or Tape & Reel) affects handling and automated assembly processes but does not affect the electrical or mechanical characteristics of the component itself. All substitute parts use identical 16-TSSOP surface mount packages suitable for standard PCB assembly equipment.
