Substitute Part Grouping Explanation

Substitution of the MAX4372HESA-T is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Amplifier type classification as current sense amplifier
• Single circuit configuration
• Identical -3dB bandwidth of 110 kHz
• Matching input bias current of 2 µA
• Identical input offset voltage of 300 µV
• Matching supply current of 30 µA
• Supply voltage range spanning minimum 2.7 V to maximum 28 V
• Operating temperature range of -40°C to 85°C

Mechanical & Packaging Equivalence Criteria:

• 8-SOIC surface mount package with 0.154" (3.90mm) width
• Identical pin configuration and footprint

Compliance Equivalence Criteria:

• ROHS3 compliance status
• MSL rating of 1 (Unlimited)
• REACH unaffected status
• EAR99 ECCN classification

The substitute part must satisfy all electrical parameters without deviation, maintain identical mechanical packaging, and preserve all regulatory compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The MAX4372HESA+T serves as a direct functional equivalent to the MAX4372HESA-T. Both parts are manufactured by Analog Devices Inc./Maxim Integrated and share identical electrical specifications, mechanical packaging, and regulatory compliance certifications.

Product Status Consideration: The MAX4372HESA-T is classified as obsolete, while the MAX4372HESA+T maintains active product status. For new designs and ongoing procurement, the MAX4372HESA+T is the appropriate selection to ensure long-term component availability and manufacturer support.

Packaging Format Difference: The primary distinction between these parts is the delivery format. The MAX4372HESA-T is supplied in tube packaging, while the MAX4372HESA+T is supplied in Tape & Reel (TR) format. This difference affects procurement logistics and automated assembly processes but does not impact electrical performance or functional compatibility.

Compliance & Certification: Both parts maintain ROHS3 compliance, MSL rating of 1 (Unlimited), REACH unaffected status, and EAR99 ECCN classification, ensuring regulatory equivalence for applications requiring these certifications.

Frequently Asked Questions (FAQ)

Q: Can MAX4372HESA+T be used as a direct replacement for MAX4372HESA-T in existing designs?

A: Yes. The MAX4372HESA+T is electrically and mechanically identical to the MAX4372HESA-T. All electrical parameters, operating ranges, and package dimensions are equivalent. The parts are pin-for-pin compatible and require no circuit modifications.

Q: What is the difference between the tube and Tape & Reel packaging formats?

A: Tube packaging supplies components in a plastic tube for manual handling and lower-volume applications. Tape & Reel (TR) packaging supplies components on continuous tape wound on a reel, optimized for automated pick-and-place assembly equipment. Both formats contain identical components with no electrical or functional differences.

Q: Why is the MAX4372HESA-T listed as obsolete?

A: Product obsolescence is determined by the manufacturer based on market demand and production decisions. The MAX4372HESA+T, with active product status, represents the current manufacturing offering for this current sense amplifier design.

Q: Are there any thermal or performance differences between these parts?

A: No. Both parts operate across the identical temperature range of -40°C to 85°C and maintain identical electrical specifications including bandwidth, input offset voltage, supply current, and bias current.

Q: What certifications apply to both parts?

A: Both the MAX4372HESA-T and MAX4372HESA+T are ROHS3 compliant, carry MSL rating 1 (Unlimited), are REACH unaffected, and classified under EAR99 ECCN.

Q: Can I mix tube and Tape & Reel packaging in the same production run?

A: Yes, from an electrical and functional standpoint. However, production logistics and assembly equipment compatibility should be evaluated. Automated assembly lines typically require Tape & Reel format, while manual assembly or prototyping may accommodate tube packaging.

Q: Is the MAX4372HESA+T available in higher inventory quantities?

A: The MAX4372HESA+T shows 890 pieces in stock compared to 744 pieces for the MAX4372HESA-T. As an active product, the MAX4372HESA+T typically maintains better long-term availability.
