Engineering Selection Recommendations

Primary Substitute: MAX4373TESA+T

The MAX4373TESA+T is the direct equivalent substitute for the MAX4373TESA-T. Both components share identical electrical specifications, package geometry, and regulatory compliance certifications. The substitute part carries active product status, ensuring ongoing manufacturer support and supply chain availability.

The key distinction between the main part and substitute is packaging format. The MAX4373TESA+T is supplied in Tape & Reel (TR) format, which is the standard production packaging for active components. The main part (MAX4373TESA-T) does not specify a packaging format, indicating it may be available in alternative formats or as legacy stock.

Both parts maintain ROHS3 compliance, REACH unaffected status, and identical moisture sensitivity specifications, confirming full compatibility for circuit design and manufacturing processes.

Frequently Asked Questions (FAQ)

Q: Can MAX4373TESA+T directly replace MAX4373TESA-T in existing designs?

A: Yes. Both parts share identical package specifications (8-SOIC, 0.154", 3.90mm Width), component type classification, and electrical function. Pin-to-pin compatibility is confirmed through matching supplier device package designation.

Q: What is the significance of the product status difference (Obsolete vs. Active)?

A: The main part (MAX4373TESA-T) is classified as obsolete, indicating discontinued production. The substitute (MAX4373TESA+T) maintains active status, ensuring continued availability from the manufacturer and authorized distributors. For new designs or long-term production requirements, the active substitute is the appropriate selection.

Q: Are there compliance or regulatory differences between these parts?

A: No. Both parts maintain identical RoHS3 compliance, REACH unaffected status, ECCN classification (EAR99), and HTSUS codes (8542.33.0001). Regulatory and environmental compliance requirements are fully satisfied by either part.

Q: What does the packaging format difference (TR) indicate?

A: Tape & Reel (TR) packaging is the standard production format for surface mount components, enabling automated assembly processes. This format difference does not affect electrical performance or physical compatibility; it reflects standard manufacturing and distribution practices for active components.

Q: Is the moisture sensitivity level identical between both parts?

A: Yes. Both parts carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity restrictions during storage, handling, or assembly processes.
