CD4053BCMX Equivalent & Substitute Parts

Part Overview

The CD4053BCMX is a 3-circuit SPDT analog switch manufactured by onsemi, designed for signal routing and multiplexing applications in 16-SOIC surface mount packaging. This part operates across a wide supply voltage range (5V to 15V single supply, or ±2.5V to ±7.5V dual supply) with 240Ω maximum on-state resistance and 40MHz bandwidth capability. The CD4053BCMX is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing production support. Substitute parts maintain the core 3-circuit SPDT 2:1 multiplexer functionality while offering variations in on-state resistance, bandwidth, supply voltage ranges, and product status.

Substitute Part Grouping Explanation

Substitution eligibility for the CD4053BCMX is determined by the following core parameters: switch circuit configuration (SPDT), multiplexer circuit type (2:1), number of circuits (3), package type (16-SOIC), and mounting method (surface mount). All substitute parts listed maintain these fundamental characteristics.

Substitute parts are grouped into three functional categories based on on-state resistance and bandwidth performance:

Category 1 - Higher Resistance, Lower Bandwidth (280Ω, 17MHz): MC14053BDG and MC14053BDR2G provide extended supply voltage range (3V to 18V single supply) but operate at reduced bandwidth and higher on-state resistance compared to the main part.

Category 2 - Lower Resistance, Higher Bandwidth (100Ω, 120MHz): MC74HC4053ADG, MC74HC4053ADR2G, and MC74VHC4053DR2G offer improved performance with lower on-state resistance and significantly higher bandwidth, suitable for applications requiring faster switching and lower signal attenuation. These parts operate at reduced supply voltage range (2V to 6V single supply).

Category 3 - Very Low Resistance, High Bandwidth (26Ω, 80MHz): MC74LVX4053DR2G and MC74LVXT4053DR2G provide the lowest on-state resistance with moderate bandwidth, optimized for low-voltage applications (2.5V to 6V single supply).

Category 4 - Moderate Resistance, Very High Bandwidth (120Ω, 170MHz): 74HC4053D,653 and 74HCT4053D,118 from Nexperia deliver the highest bandwidth performance with moderate on-state resistance and improved switching speed characteristics.

Engineering Selection Recommendations

All substitute parts listed maintain the core 3-circuit SPDT 2:1 multiplexer architecture and 16-SOIC surface mount package required for direct replacement. Selection should be based on application-specific requirements for supply voltage range, on-state resistance, and bandwidth performance.

For applications requiring the widest supply voltage range with active product status, MC14053BDG and MC14053BDR2G support 3V to 18V single supply operation. These parts are suitable for legacy designs transitioning from the obsolete CD4053BCMX where extended voltage flexibility is required.

For applications operating at 2V to 6V supply voltages with performance optimization, MC74HC4053ADG, MC74HC4053ADR2G, and MC74VHC4053DR2G provide 100Ω on-state resistance and 120MHz bandwidth. All three are ROHS3 compliant with active product status.

For low-voltage applications (2.5V to 6V) requiring minimal on-state resistance, MC74LVX4053DR2G and MC74LVXT4053DR2G deliver 26Ω resistance with 80MHz bandwidth. MC74LVXT4053DR2G extends dual supply capability to ±6V compared to MC74LVX4053DR2G's ±3V limit.

For highest bandwidth performance (170MHz) with moderate on-state resistance (120Ω), 74HC4053D,653 from Nexperia supports 2V to 10V single supply and ±1.5V to ±5V dual supply with improved switching speed (31ns/29ns). The 74HCT4053D,118 variant restricts single supply to 4.5V to 5.5V but maintains equivalent bandwidth and switching characteristics.

All active substitute parts carry ROHS3 compliance and MSL 1 (unlimited) moisture sensitivity rating, matching the environmental specifications of the original CD4053BCMX.

Frequently Asked Questions (FAQ)

Q: Can MC14053BDG directly replace CD4053BCMX in existing designs?

A: MC14053BDG maintains identical switch circuit configuration (SPDT), multiplexer type (2:1), circuit count (3), and 16-SOIC package. However, on-state resistance increases from 240Ω to 280Ω, bandwidth decreases from 40MHz to 17MHz, and supply voltage range expands to 3V to 18V. Designs operating within 5V to 15V supply range and tolerating higher resistance and lower bandwidth can use this substitute.

Q: What is the primary difference between MC74HC4053ADG and MC74VHC4053DR2G?

A: Both parts share identical electrical specifications: 100Ω on-state resistance, 120MHz bandwidth, 2V to 6V single supply, and ±2V to ±6V dual supply. The primary difference is packaging: MC74HC4053ADG is supplied in Tube packaging, while MC74VHC4053DR2G uses Tape & Reel (TR) packaging. Electrical performance and compatibility are equivalent.

Q: Why does 74HCT4053D,118 have a narrower supply voltage range than 74HC4053D,653?

A: 74HCT4053D,118 is a TTL-compatible variant designed for 4.5V to 5.5V single supply operation, whereas 74HC4053D,653 is a standard CMOS variant supporting 2V to 10V. Both deliver identical 120Ω on-state resistance and 170MHz bandwidth. Selection depends on system supply voltage requirements.

Q: Are all substitute parts ROHS3 compliant?

A: All substitute parts listed carry ROHS3 compliance certification. The original CD4053BCMX does not specify RoHS status. All active substitutes meet current environmental compliance requirements.

Q: What is the operating temperature range difference between CD4053BCMX and Nexperia substitutes?

A: CD4053BCMX operates from -55°C to 125°C. Nexperia parts (74HC4053D,653 and 74HCT4053D,118) operate from -40°C to 125°C, providing a narrower low-temperature range. Applications requiring -55°C operation must use onsemi or Fairchild alternatives.

Q: Can MC74LVX4053DR2G replace CD4053BCMX in high-frequency applications?

A: MC74LVX4053DR2G provides 26Ω on-state resistance (lower than CD4053BCMX's 240Ω) but operates at 80MHz bandwidth compared to CD4053BCMX's 40MHz. Supply voltage range is restricted to 2.5V to 6V single supply. This part is suitable for low-voltage, moderate-frequency applications but not for designs requiring the original part's 5V to 15V supply range.

Q: What packaging options are available for the MC74HC4053 series?

A: MC74HC4053ADG is supplied in Tube packaging, while MC74HC4053ADR2G uses Tape & Reel (TR) packaging. Both maintain identical 16-SOIC package dimensions and electrical specifications. Selection depends on production volume and handling requirements.
