Engineering Selection Recommendations
For Direct Replacement (Identical Electrical Performance)
MC74HC4052ADWR2G is the recommended primary substitute. This part is currently in active product status, maintains identical on-state resistance (100Ohm maximum) and supply voltage specifications (2V ~ 6V single, ±2V ~ 6V dual), and is available in Tape & Reel packaging for production quantities. It provides improved bandwidth (95MHz versus 35MHz) and superior crosstalk performance (-60dB versus -50dB @ 1MHz), with ROHS3 compliance and extended operating temperature range (-55°C ~ 125°C).
MC74HC4052ADWG serves as a secondary option with identical electrical specifications but is listed as obsolete. This part is available in Tube packaging and may be suitable for limited-quantity applications where packaging format is not a constraint.
For Applications with Extended Supply Voltage Requirements
HEF4052BT,653 is suitable for applications requiring higher supply voltage operation (3V ~ 15V single supply). This Nexperia part is in active product status with unlimited moisture sensitivity (MSL 1), making it appropriate for standard manufacturing environments. The higher on-state resistance (155Ohm maximum) and absence of dual supply support require circuit-level evaluation for compatibility.
HEF4052BT,013 is discontinued at DiGi Electronics and should not be selected for new designs despite its technical specifications.
Compliance and Regulatory Considerations
All recommended substitute parts maintain REACH Unaffected status and ECCN EAR99 classification, consistent with the original MM74HC4052WMX. MC74HC4052ADWR2G and HEF4052BT,653 are ROHS3 compliant and represent the most suitable choices for applications subject to environmental and regulatory compliance requirements.
Frequently Asked Questions (FAQ)
Q: Can MC74HC4052ADWR2G be used as a direct replacement for MM74HC4052WMX?
A: Yes. Both parts share identical switch circuit configuration (SP4T), number of circuits (2), multiplexer circuit (4:1), on-state resistance (100Ohm maximum), and supply voltage specifications (2V ~ 6V single, ±2V ~ 6V dual). The MC74HC4052ADWR2G is in active product status and offers improved performance characteristics including higher bandwidth (95MHz) and better crosstalk isolation (-60dB @ 1MHz).
Q: What is the difference between MC74HC4052ADWG and MC74HC4052ADWR2G?
A: Both parts are electrically identical with the same on-state resistance, supply voltage range, and core switching specifications. The primary difference is packaging: MC74HC4052ADWG is supplied in Tube format, while MC74HC4052ADWR2G is supplied in Tape & Reel (TR) format. MC74HC4052ADWR2G is in active product status, whereas MC74HC4052ADWG is obsolete. For production applications, MC74HC4052ADWR2G is the preferred choice.
Q: Can HEF4052BT,653 replace MM74HC4052WMX in all applications?
A: HEF4052BT,653 is functionally compatible as a 2-circuit SP4T 4:1 multiplexer in 16-SOIC packaging. However, it operates at higher supply voltages (3V ~ 15V single supply only, no dual supply option) and has higher on-state resistance (155Ohm maximum versus 100Ohm). Applications requiring 2V supply operation or dual supply (±2V ~ 6V) cannot use this part. Circuit-level evaluation is required to confirm compatibility with your specific application requirements.
Q: What are the package differences between the onsemi and Nexperia parts?
A: Both onsemi parts (MC74HC4052ADWG and MC74HC4052ADWR2G) use 16-SOIC packaging with 0.295" (7.50mm) width. The Nexperia parts (HEF4052BT,013 and HEF4052BT,653) use 16-SO packaging with 0.154" (3.90mm) width. While both are 16-pin SOIC packages, the different body widths may affect PCB layout compatibility. Verify footprint dimensions against your design before selection.
Q: Are there any moisture sensitivity considerations for these substitutes?
A: MM74HC4052WMX has MSL 1 (unlimited moisture sensitivity). MC74HC4052ADWG and MC74HC4052ADWR2G have MSL 3 (168 hours), requiring controlled storage and handling during manufacturing. HEF4052BT,013 and HEF4052BT,653 have MSL 1 (unlimited), matching the original part's moisture tolerance. For applications with extended lead times or storage requirements, HEF4052BT,653 may be preferable from a moisture management perspective.
Q: Which substitute part has the best availability?
A: MC74HC4052ADWR2G has the highest reported inventory (4400 Pcs New Original In Stock) and is in active product status, making it the most readily available option. HEF4052BT,653 is also in active status with substantial inventory (13331 Pcs). Both parts are suitable for immediate procurement.
