Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX197BCWI is determined by strict equivalence across the following critical parameters:

• Resolution (Bits): 12-bit conversion capability
• Number of Channels: 8-channel configuration
• Sampling Rate (Per Second): 100 kHz maximum sampling frequency
• Data Interface: Parallel output protocol
• Voltage Supply Source: Single supply operation
• Package / Case: 28-SOIC form factor with identical physical dimensions
• Mounting Type: Surface mount technology

The MAX197BCWI+ qualifies as a direct substitute based on identical performance specifications across all electrical and mechanical parameters. The primary distinction is product status and compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The MAX197BCWI+ is the direct substitute for the obsolete MAX197BCWI. Both devices are electrically and mechanically identical across all functional parameters. The MAX197BCWI+ is currently in active production status, ensuring long-term availability and supply chain reliability.

The MAX197BCWI+ provides additional compliance advantage through ROHS3 certification, whereas the original MAX197BCWI is RoHS non-compliant. For new designs or system updates subject to RoHS requirements, the MAX197BCWI+ is the appropriate selection. Both devices maintain identical REACH and ECCN classifications.

Frequently Asked Questions (FAQ)

Q: Can the MAX197BCWI+ be used as a direct replacement for the MAX197BCWI in existing designs?

A: Yes. The MAX197BCWI+ is electrically and mechanically equivalent. Both devices feature identical 12-bit resolution, 8-channel configuration, 100 kHz sampling rate, parallel data interface, and 28-SOIC package dimensions. Pin-for-pin compatibility is maintained.

Q: What is the primary difference between MAX197BCWI and MAX197BCWI+?

A: The MAX197BCWI+ is the active production variant with ROHS3 compliance certification. The original MAX197BCWI is classified as obsolete and is RoHS non-compliant. Electrical and mechanical specifications are identical.

Q: Are there any supply voltage differences between these parts?

A: The MAX197BCWI+ specifies a supply voltage range of 4.75V to 5.25V. The original MAX197BCWI does not include explicit voltage specification in the provided data. Both operate as single supply devices within the 0°C to 70°C temperature range.

Q: Is the 28-SOIC package identical for both parts?

A: Yes. Both the MAX197BCWI and MAX197BCWI+ use the 28-SOIC package with 0.295" width and 7.50mm physical dimensions. Surface mount assembly compatibility is maintained.

Q: What is the moisture sensitivity level for these devices?

A: Both devices are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
