Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX198BCWI is determined by strict equivalence across the following critical parameters:

• Resolution (Bits): 12-bit conversion capability
• Number of Channels: 6-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 MAX198BCWI+ qualifies as a direct substitute based on identical electrical specifications and mechanical compatibility across all parameters listed above.

Parameter Comparison

Engineering Selection Recommendations

The MAX198BCWI+ serves as the direct substitute for the obsolete MAX198BCWI. Both components share identical electrical and mechanical specifications, ensuring pin-for-pin compatibility and functional equivalence in existing circuit designs.

The MAX198BCWI+ offers the additional advantage of active product status, ensuring continued availability and manufacturing support. The MAX198BCWI+ achieves ROHS3 compliance, whereas the original MAX198BCWI is RoHS non-compliant. For applications requiring RoHS compliance or long-term component availability, the MAX198BCWI+ is the appropriate selection.

Both components maintain identical moisture sensitivity classification (MSL 1), operating temperature range (0°C to 70°C), and package specifications, eliminating the need for PCB redesign or thermal management modifications during substitution.

Frequently Asked Questions (FAQ)

Q: Can the MAX198BCWI+ be used as a direct replacement for the MAX198BCWI?

A: Yes. The MAX198BCWI+ is electrically and mechanically equivalent to the MAX198BCWI. Both components feature 12-bit resolution, 6 channels, 100 kHz sampling rate, parallel data interface, and identical 28-SOIC packaging. No circuit modifications are required for substitution.

Q: What is the primary difference between the MAX198BCWI and MAX198BCWI+?

A: The MAX198BCWI+ is an active product with ROHS3 compliance, whereas the MAX198BCWI is obsolete and RoHS non-compliant. The MAX198BCWI+ provides improved long-term availability and regulatory compliance for new designs and system updates.

Q: Are there any package or pinout differences between these components?

A: No. Both the MAX198BCWI and MAX198BCWI+ use the 28-SOIC package with identical physical dimensions (0.295", 7.50mm width) and pinout configuration. PCB layout and footprints require no modification.

Q: What supply voltage does the MAX198BCWI+ require?

A: The MAX198BCWI+ operates on a single supply voltage of 4.75V to 5.25V. The original MAX198BCWI does not specify a voltage range in the provided documentation.

Q: Is the MAX198BCWI+ suitable for applications requiring RoHS compliance?

A: Yes. The MAX198BCWI+ is ROHS3 compliant and meets regulatory requirements for RoHS-restricted applications. The original MAX198BCWI is RoHS non-compliant.
