Engineering Selection Recommendations

Primary Substitutes (Direct Electrical Equivalents)

SN74HC4852DR and SN74HC4852QDRQ1 from Texas Instruments are the preferred substitutes for the 74HC4852D,112. Both maintain the 195Ohm on-state resistance specification, matching switch timing characteristics (39ns, 78ns), and identical supply voltage range. SN74HC4852DR is available in Last Time Buy status with extended temperature range (-40°C ~ 125°C). SN74HC4852QDRQ1 carries automotive-grade qualification (AEC-Q100) and is suitable for applications requiring automotive reliability standards.

SN74HC4852D from Texas Instruments provides electrical equivalence but operates within a reduced temperature range (-40°C ~ 85°C), limiting its use to applications not requiring full -40°C ~ 125°C coverage.

Secondary Substitute (Functional Equivalent with Performance Trade-offs)

MC74HC4852ADR2G from onsemi maintains core SP4T topology and dual-circuit configuration with identical supply voltage compatibility. However, this part features 400Ohm on-state resistance (double the original specification) and higher channel capacitance (40pF versus 10pF). This substitute is suitable only for applications where increased on-state resistance and capacitance do not degrade signal integrity or bandwidth requirements. MC74HC4852ADR2G is currently in Active production status, offering superior long-term availability compared to Last Time Buy alternatives.

Compliance and Certification Considerations

All substitute parts maintain ROHS3 compliance and EAR99 export classification, matching the original part's regulatory status. SN74HC4852QDRQ1 includes AEC-Q100 automotive qualification for designs requiring automotive-grade component certification.

Frequently Asked Questions (FAQ)

Q: Can MC74HC4852ADR2G replace the 74HC4852D,112 in all applications?

A: MC74HC4852ADR2G is functionally compatible for SP4T switching applications but features 400Ohm on-state resistance versus the original 195Ohm specification. This higher resistance may impact signal attenuation and bandwidth in sensitive analog signal routing circuits. Verify that your application tolerates doubled on-state resistance and increased channel capacitance (40pF) before substitution.

Q: What is the difference between SN74HC4852D and SN74HC4852DR?

A: Both parts are electrically identical with 195Ohm on-state resistance and matching switch timing. The primary difference is packaging format: SN74HC4852D is supplied in Tube packaging, while SN74HC4852DR uses Cut Tape (CT) & Digi-Reel® format. SN74HC4852DR also supports the full -40°C ~ 125°C temperature range, whereas SN74HC4852D is limited to -40°C ~ 85°C.

Q: Is SN74HC4852QDRQ1 suitable for non-automotive applications?

A: Yes. SN74HC4852QDRQ1 meets all electrical and package requirements for general-purpose applications. The automotive-grade qualification (AEC-Q100) and Tape & Reel packaging make it suitable for high-reliability designs across automotive and industrial sectors. Its extended temperature range (-40°C ~ 125°C) and matching electrical specifications provide equivalent performance to standard-grade alternatives.

Q: Why does the 74HC4852D,112 require substitution?

A: The 74HC4852D,112 is classified as Obsolete, indicating discontinued manufacturing and limited remaining inventory. Substitution ensures design continuity and long-term supply chain stability for new production runs and field replacements.

Q: Are all substitute parts available in 16-SOIC package?

A: Yes. All listed substitute parts (SN74HC4852D, SN74HC4852DR, SN74HC4852QDRQ1, and MC74HC4852ADR2G) are manufactured in 16-SOIC (0.154", 3.90mm Width) surface mount packages, ensuring direct PCB compatibility with the original 74HC4852D,112 design.

Q: What is the impact of higher leakage current in Texas Instruments substitutes?

A: Texas Instruments parts (SN74HC4852D, SN74HC4852DR, SN74HC4852QDRQ1) specify 200nA maximum leakage current versus 100nA for the original part and MC74HC4852ADR2G. This doubling of leakage current is within acceptable limits for most analog switching applications but may require verification in ultra-low-power or high-impedance signal circuits.
