Substitute Part Grouping Explanation

Substitution of the MAX4667ESE is determined by strict equivalence across all electrical and mechanical parameters. The substitute part must maintain identical specifications for:

Switch circuit topology (SPST - NC configuration)
Circuit count (2 circuits)
Multiplexer ratio (1:1)
On-state resistance and channel matching characteristics
Supply voltage ranges (both single and dual supply modes)
Switching time performance
Charge injection and capacitance parameters
Leakage current specifications
Crosstalk performance
Operating temperature range
Physical package dimensions (16-SOIC form factor)
Surface mount compatibility

The MAX4667ESE+ meets all these criteria and serves as a direct electrical and mechanical equivalent.

Engineering Selection Recommendations

The MAX4667ESE+ is the direct substitute for the MAX4667ESE. Both parts are electrically and mechanically identical across all functional parameters. The primary distinction is product status and regulatory compliance:

The MAX4667ESE is obsolete and carries RoHS non-compliant status. The MAX4667ESE+ is an active product with ROHS3 compliance, making it the appropriate selection for new designs and ongoing production requirements. Both parts maintain identical MSL rating (1 - Unlimited) and REACH status, ensuring equivalent handling and environmental compliance profiles.

For applications requiring the MAX4667ESE, direct substitution with MAX4667ESE+ is supported without circuit modification or re-qualification.

Frequently Asked Questions (FAQ)

Q: Can MAX4667ESE+ replace MAX4667ESE in existing designs?

A: Yes. The MAX4667ESE+ is electrically and mechanically equivalent to the MAX4667ESE. All electrical parameters, switching characteristics, and package dimensions are identical. Direct substitution is supported without design changes.

Q: What is the difference between MAX4667ESE and MAX4667ESE+?

A: The primary differences are product status and RoHS compliance. The MAX4667ESE is obsolete and RoHS non-compliant. The MAX4667ESE+ is an active product with ROHS3 compliance. Electrical and mechanical specifications are identical.

Q: Are there any packaging differences between these parts?

A: The MAX4667ESE is supplied in standard packaging, while the MAX4667ESE+ is supplied in Tube packaging. Both use the 16-SOIC (0.154", 3.90mm Width) form factor with identical pin configuration and footprint.

Q: What supply voltage configurations does this IC support?
