Substitute Part Grouping Explanation
Substitution of the MAX167CENG is based on strict equivalence across the following critical parameters:
- Resolution: 12 bits (matching data precision requirements)
- Sampling Rate: 100 kSPS (matching conversion speed)
- Input Configuration: 1 single-ended input (matching signal acquisition topology)
- Data Interface: Parallel (matching system integration requirements)
- Architecture: SAR (matching conversion methodology)
- Reference Type: Internal (matching reference implementation)
- Supply Voltages: 5V and -12V to 15V for both analog and digital domains (matching power distribution)
- Operating Temperature: -40°C to 85°C (matching environmental specifications)
- Package: 24-DIP through-hole (matching PCB layout and assembly requirements)
The MAX163CENG+ meets all these criteria and is classified as an active product, providing a direct parametric equivalent for the obsolete MAX167CENG.

Engineering Selection Recommendations
The MAX163CENG+ is the direct parametric equivalent for the MAX167CENG across all specified electrical and mechanical parameters. The primary distinction is product lifecycle status: the MAX167CENG is obsolete, while the MAX163CENG+ is active and in production.
The MAX163CENG+ provides an additional compliance advantage: it is ROHS3 compliant, whereas the MAX167CENG is RoHS non-compliant. This compliance improvement aligns with current regulatory requirements for electronic components in most markets.
Both parts share identical electrical specifications, package geometry, and mounting methodology, enabling direct substitution in existing designs without circuit modification or PCB redesign.
Frequently Asked Questions (FAQ)
Q: Can the MAX163CENG+ directly replace the MAX167CENG in existing designs?
A: Yes. The MAX163CENG+ is a parametric equivalent with identical resolution (12 bits), sampling rate (100 kSPS), input configuration (1 single-ended), data interface (parallel), architecture (SAR), reference type (internal), supply voltages (5V and -12V to 15V), operating temperature range (-40°C to 85°C), and package type (24-DIP through-hole). No circuit or PCB modifications are required.
