CD4053BCN Equivalent & Substitute Parts

Part Overview

The CD4053BCN is a 3-circuit SPDT (Single Pole Double Throw) analog switch IC manufactured by onsemi in a 16-DIP package. This component functions as a 2:1 multiplexer/demultiplexer with 240Ohm on-state resistance and operates across a wide supply voltage range of 5V to 15V (single supply) or ±2.5V to ±7.5V (dual supply). The CD4053BCN is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the CD4053BCN is determined by the following critical parameters: switch circuit type (SPDT), multiplexer configuration (2:1), number of circuits (3), package type (16-DIP), and operating temperature range (-55°C to 125°C). The substitute parts are grouped into two categories based on electrical compatibility:

Direct Substitutes (Functional Equivalents): Parts that maintain the same on-state resistance specification (240Ohm) and supply voltage ranges compatible with the original design. The CD4053BE from Texas Instruments qualifies as a direct substitute with identical electrical characteristics and package configuration.

Similar Substitutes (Parameter Variations): Parts that share the same circuit topology, package, and temperature range but differ in on-state resistance (130Ohm), supply voltage ranges, and bandwidth specifications. The CD74HC4053E and CD74HCT4053E fall into this category, offering improved performance characteristics at the cost of different electrical parameters that may require circuit redesign validation.

Parameter Comparison

Engineering Selection Recommendations

CD4053BE (Texas Instruments): This part is the recommended direct substitute for the CD4053BCN. It maintains identical on-state resistance (240Ohm), channel matching (5Ohm), and operating temperature range. The CD4053BE offers extended supply voltage compatibility (3V to 20V single supply, ±2.5V to ±9V dual supply) compared to the original specification. The part is currently in active production status with ROHS3 compliance, ensuring long-term availability and regulatory alignment for new designs.

CD74HC4053E (Texas Instruments): This part is suitable as a substitute only when circuit design permits operation within its narrower supply voltage range (2V to 6V single supply, ±1V to ±5V dual supply). The CD74HC4053E offers superior performance with reduced on-state resistance (130Ohm) and significantly higher bandwidth (200MHz versus 40MHz). This part is classified as Last Time Buy, indicating limited future availability. ROHS3 compliance is confirmed.

CD74HCT4053E (Harris Corporation): This part shares the same circuit topology and package as the CD74HC4053E but is restricted to a narrow supply voltage window (4.5V to 5.5V single supply). The CD74HCT4053E is obsolete and non-ROHS compliant, making it unsuitable for new designs requiring regulatory compliance. This part is listed for reference only in legacy system maintenance scenarios.

Frequently Asked Questions (FAQ)

Q: Can the CD4053BE directly replace the CD4053BCN without circuit modifications?

A: Yes. The CD4053BE maintains identical on-state resistance (240Ohm), channel matching (5Ohm), and operating temperature specifications. The extended supply voltage range of the CD4053BE (3V to 20V) is backward compatible with the original CD4053BCN specification (5V to 15V). No circuit redesign is required for direct substitution.

Q: What are the key differences between the CD4053BE and CD74HC4053E?

A: The primary differences are on-state resistance (240Ohm versus 130Ohm), supply voltage range (3V-20V versus 2V-6V for single supply), and bandwidth (30MHz versus 200MHz). The CD74HC4053E requires verification that the application circuit operates within its narrower supply voltage specification. The reduced on-state resistance of the CD74HC4053E may affect signal attenuation characteristics in analog switching applications.

Q: Is the CD74HCT4053E suitable for new production designs?

A: No. The CD74HCT4053E is classified as obsolete and is not ROHS3 compliant. This part should be used only for legacy system maintenance where the original specification is mandatory. For new designs, the CD4053BE or CD74HC4053E are the appropriate selections.

Q: What is the significance of the 16-DIP package specification?

A: All substitute parts listed maintain the 16-DIP (0.300", 7.62mm) package configuration, ensuring mechanical and electrical compatibility with existing PCB layouts and socket designs. No board redesign is necessary when substituting between these parts.

Q: How do the leakage current specifications compare?

A: The CD4053BCN specifies a maximum leakage current of 50nA, while all substitute parts (CD4053BE, CD74HC4053E, CD74HCT4053E) specify 100nA. This difference is within acceptable tolerances for most analog switching applications but should be verified in precision measurement circuits where leakage current is a critical parameter.

Q: What compliance certifications should be verified for new designs?

A: The CD4053BE and CD74HC4053E both carry ROHS3 compliance certification, meeting current regulatory requirements for electronic components. The CD74HCT4053E is non-ROHS compliant and should not be selected for applications requiring regulatory compliance documentation.
