Engineering Selection Recommendations

All substitute DC-DC converter models listed are designated as "Active" and are available in surface mount packaging. All evaluated substitutes hold ROHS3 compliant status and meet MSL 1 (Unlimited) moisture sensitivity requirements. ECCN and REACH statuses are specified per model; most substitutes are REACH Unaffected. Product selection should be based on matching electrical parameters, mechanical form factor, and compliance identifiers as detailed above. Substitute modules are restricted to those that adhere strictly to these parameters as per provided manufacturer documentation.
