Substitute Part Grouping Explanation
Substitution of the MAX396CPI is determined by strict equivalence across the following electrical and mechanical parameters:
- Multiplexer configuration: 16:1 topology
- Circuit count: Single circuit
- On-state resistance: 100Ohm maximum
- Channel-to-channel matching: 1.8Ohm
- Supply voltage ranges: Single supply 2.7V ~ 16V and dual supply ±2.7V ~ 8V
- Switching performance: 150ns maximum for both Ton and Toff
- Charge injection: 2pC
- Channel capacitance specifications: 11pF and 80pF
- Leakage current: 100pA maximum
- Crosstalk performance: -92dB @ 100kHz
- Operating temperature range: 0°C ~ 70°C
- Package form factor: 28-DIP through-hole mounting
The MAX396CPI+ meets all these criteria and is identified as a direct substitute.

Engineering Selection Recommendations
The MAX396CPI+ is the direct functional equivalent of the MAX396CPI. Both parts share identical electrical specifications and package form factors. The primary distinction is product status: the MAX396CPI is obsolete while the MAX396CPI+ is active and currently in production.
For new designs and ongoing production requirements, the MAX396CPI+ is the appropriate selection. This part maintains full electrical and mechanical compatibility with the original MAX396CPI while offering the advantage of active product status and ROHS3 compliance. The MAX396CPI+ is supplied in tube packaging, whereas the original part was supplied in standard packaging.
Frequently Asked Questions (FAQ)
Q: Can MAX396CPI+ be used as a direct replacement for MAX396CPI in existing designs?
A: Yes. The MAX396CPI+ is electrically and mechanically identical to the MAX396CPI. All electrical parameters, including multiplexer configuration, on-state resistance, supply voltage ranges, switching times, and package dimensions are equivalent. Pin-for-pin compatibility is maintained.
Q: What is the primary reason to transition from MAX396CPI to MAX396CPI+?
A: The MAX396CPI is classified as obsolete. The MAX396CPI+ is the active equivalent part, ensuring continued availability for production and new designs. Additionally, the MAX396CPI+ is ROHS3 compliant, whereas the original part is RoHS non-compliant.
Q: Are there any differences in packaging between these parts?
A: Both parts use 28-DIP through-hole packages with identical physical dimensions (0.600", 15.24mm). The MAX396CPI+ is supplied in tube packaging, while the original MAX396CPI was supplied in standard packaging. This difference does not affect electrical performance or board-level compatibility.
Q: What are the key electrical parameters that define substitution eligibility?
A: Substitution is based on 16:1 multiplexer configuration, 100Ohm on-state resistance, 1.8Ohm channel-to-channel matching, 2.7V ~ 16V single supply voltage range, ±2.7V ~ 8V dual supply voltage range, 150ns switching times, 2pC charge injection, 11pF and 80pF channel capacitance, 100pA maximum leakage current, and -92dB crosstalk at 100kHz.
Q: Is the MAX396CPI+ suitable for applications requiring RoHS compliance?
A: Yes. The MAX396CPI+ is ROHS3 compliant, making it suitable for applications with RoHS requirements. The original MAX396CPI is RoHS non-compliant.
