Parameter Comparison

Engineering Selection Recommendations

The S-816A45AMC-BAUT2U serves as the direct parametric equivalent to the S-816A45AMC-BAUT2G. Both parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

The primary distinction is product lifecycle status: S-816A45AMC-BAUT2G is designated "Not For New Designs," while S-816A45AMC-BAUT2U maintains "Active" status. For applications requiring long-term supply assurance and manufacturer support, the active substitute is the appropriate selection. Both parts share identical electrical performance, thermal operating range, and mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Are S-816A45AMC-BAUT2G and S-816A45AMC-BAUT2U pin-compatible?

A: Yes. Both parts use the SOT-23-5 package (SC-74A, SOT-753) with identical pinout and electrical characteristics, enabling direct board-level substitution without circuit modification.

Q: What is the significance of "Not For New Designs" status?

A: This designation indicates the manufacturer no longer recommends the part for new product development. Existing designs may continue using available inventory, but new applications should transition to the active equivalent.

Q: Can I use S-816A45AMC-BAUT2U in place of S-816A45AMC-BAUT2G?

A: Yes. The substitute part maintains identical specifications across all critical parameters: input voltage (16V), supply current (40µA), operating temperature range (-40°C to 85°C), output configuration (single output), and package type (SOT-23-5). No design changes are required.

Q: Are there compliance differences between these parts?

A: No. Both parts carry identical compliance certifications: ROHS3 Compliant, REACH Unaffected, with MSL rating of 1 (Unlimited).

Q: Which part should I specify for new designs?

A: Specify S-816A45AMC-BAUT2U, which carries Active product status and ensures ongoing manufacturer support and supply availability.
