Substitute Part Grouping Explanation

Substitution of the MAX138CPL is determined by strict equivalence across the following critical parameters:

• Functional Type: ADC with 4.6-digit resolution and dual-channel configuration
• Electrical Specifications: Single supply operation within 2.5V to 7V range
• Thermal Operating Range: 0°C to 70°C
• Physical Package: 40-pin DIP form factor (0.600", 15.24mm) for through-hole mounting
• Base Product Series: MAX138 family designation

The MAX138CPL+ qualifies as a direct substitute based on identical electrical characteristics, package specifications, and functional parameters. The primary distinction is product status and compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The MAX138CPL+ is the direct substitute for the MAX138CPL. Both components share identical electrical specifications, functional parameters, and physical packaging. The MAX138CPL+ is currently in active production status, whereas the MAX138CPL is obsolete.

The MAX138CPL+ carries ROHS3 compliance certification, whereas the original MAX138CPL is RoHS non-compliant. Both components maintain REACH Unaffected status and identical export classification (EAR99). Selection between these parts should be based on regulatory requirements and supply chain availability. The MAX138CPL+ is recommended for new designs and applications requiring RoHS compliance.

Frequently Asked Questions (FAQ)

Q: Can the MAX138CPL+ be used as a direct replacement for the MAX138CPL?

A: Yes. The MAX138CPL+ is electrically and functionally equivalent to the MAX138CPL. Both components feature identical 4.6-digit ADC resolution, dual-channel configuration, 2.5V to 7V single supply operation, and 40-pin DIP packaging. Pin-for-pin compatibility is maintained.

Q: What is the primary difference between MAX138CPL and MAX138CPL+?

A: The MAX138CPL+ is the active production variant with ROHS3 compliance certification. The MAX138CPL is classified as obsolete and is RoHS non-compliant. Electrical and functional specifications are identical.

Q: Are there packaging differences between these parts?

A: Both components use the same 40-pin DIP (0.600", 15.24mm) package for through-hole mounting. The MAX138CPL is supplied in standard packaging, while the MAX138CPL+ is supplied in tube packaging. Physical dimensions and pin configuration are identical.

Q: What supply voltage range is supported?

A: Both the MAX138CPL and MAX138CPL+ operate with a single supply voltage range of 2.5V to 7V. Operating temperature range is 0°C to 70°C for both variants.

Q: Are there any compliance or certification differences?

A: The MAX138CPL+ is ROHS3 compliant, while the MAX138CPL is RoHS non-compliant. Both maintain REACH Unaffected status and EAR99 export classification. Applications requiring RoHS compliance should use the MAX138CPL+.
