CD4053BPWRG3 Equivalent & Substitute Parts

Part Overview

The CD4053BPWRG3 is a 3-circuit IC switch with 2:1 multiplexer/demultiplexer functionality manufactured by Texas Instruments. This interface component operates across a wide supply voltage range (3V to 20V single supply, or ±2.5V to 9V dual supply) and features 240Ohm on-state resistance with 30MHz bandwidth capability. The part is currently in Last Time Buy status, making identification of active equivalent and substitute parts essential for ongoing design support and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD4053BPWRG3 is determined by the following critical parameters:

Primary Substitution Criteria:

• Switch circuit type: SPDT
• Multiplexer/demultiplexer configuration: 2:1
• Number of circuits: 3
• Package type: 16-TSSOP surface mount
• Operating temperature range: -55°C ~ 125°C

Secondary Compatibility Parameters:

• On-state resistance (Max): 240Ohm baseline; substitutes with higher resistance values remain functionally compatible within circuit design tolerances
• Supply voltage ranges: Single supply 3V ~ 20V or dual supply ±2.5V ~ 9V; substitutes must support the required supply configuration
• Bandwidth and signal integrity: -3dB bandwidth of 30MHz; lower bandwidth substitutes may limit high-frequency performance
• Leakage current: 100nA maximum; substitutes with equal or lower leakage maintain signal integrity

The CD4053BPWR (Texas Instruments, Cut Tape packaging) and MC14053BDTR2G (onsemi, Tape & Reel packaging) meet these core substitution criteria while maintaining functional equivalence in standard applications.

Parameter Comparison

Engineering Selection Recommendations

CD4053BPWR (Texas Instruments): This part is the manufacturer-recommended direct substitute for the CD4053BPWRG3. Both parts share identical electrical specifications and are manufactured by Texas Instruments. The primary difference is packaging format: CD4053BPWR is supplied in Cut Tape (CT) and Digi-Reel format, while the main part uses Tape & Reel (TR) packaging. This substitute maintains full electrical and thermal compatibility and is currently in Active product status with higher inventory availability (38,312 pcs). Selection of this part eliminates Last Time Buy constraints while preserving all functional characteristics.

MC14053BDTR2G (onsemi): This part provides functional substitution with measurable parameter variations. The onsemi device exhibits higher on-state resistance (280Ohm vs. 240Ohm), reduced channel-to-channel matching precision (10Ohm vs. 5Ohm), lower bandwidth (-3dB at 17MHz vs. 30MHz), and different channel capacitance characteristics (7.5pF vs. 0.2pF/9pF). The MC14053BDTR2G does not specify dual supply voltage operation. This part is suitable for applications where the specified parameter variations remain within design tolerance margins. The device is in Active product status with substantial inventory (25,100 pcs) and maintains ROHS3 compliance and MSL 1 rating.

Both substitute parts maintain the required 16-TSSOP package format, surface mount capability, and full operating temperature range (-55°C ~ 125°C). Selection between substitutes depends on application-specific requirements for on-state resistance, bandwidth, and supply voltage configuration.

Frequently Asked Questions (FAQ)

Q: Can CD4053BPWR be used as a direct replacement for CD4053BPWRG3?

A: Yes. CD4053BPWR is the manufacturer-recommended substitute with identical electrical specifications. The only difference is packaging format (Cut Tape vs. Tape & Reel). Both parts are manufactured by Texas Instruments and share the same 16-TSSOP package footprint, making them pin-compatible and functionally equivalent.

Q: What are the key differences between CD4053BPWR and MC14053BDTR2G?

A: The primary differences are on-state resistance (240Ohm vs. 280Ohm), channel-to-channel matching (5Ohm vs. 10Ohm), -3dB bandwidth (30MHz vs. 17MHz), and channel capacitance specifications. The MC14053BDTR2G does not specify dual supply voltage operation. These variations may affect performance in high-frequency or precision analog switching applications.

Q: Is the MC14053BDTR2G suitable for applications requiring 30MHz bandwidth?

A: The MC14053BDTR2G specifies -3dB bandwidth at 17MHz, which is lower than the CD4053BPWRG3 specification of 30MHz. Applications requiring full 30MHz bandwidth performance should use CD4053BPWR or CD4053BPWRG3.

Q: Are all three parts RoHS compliant?

A: Yes. CD4053BPWRG3, CD4053BPWR, and MC14053BDTR2G are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Both packaging formats contain the same 16-TSSOP component. Tape & Reel (TR) packaging supplies components on continuous tape in reel format for automated assembly. Cut Tape (CT) and Digi-Reel packaging supplies components on tape segments or alternative reel formats. The electrical and functional performance is identical; packaging selection depends on assembly equipment compatibility and procurement requirements.

Q: Can MC14053BDTR2G be used in dual supply voltage applications?

A: The MC14053BDTR2G datasheet does not specify dual supply voltage (V±) operation. Applications requiring dual supply voltage operation should use CD4053BPWR or CD4053BPWRG3, both of which support ±2.5V ~ 9V dual supply configuration.

Q: Why is CD4053BPWRG3 marked as Last Time Buy?

A: Last Time Buy status indicates that Texas Instruments is discontinuing this specific part number variant. CD4053BPWR (the same device in alternative packaging) remains in Active status and is the recommended transition path for ongoing procurement.
