Engineering Selection Recommendations
The LDD-1200LS is marked as obsolete, while the NLDD-1200H remains active in production. Both models possess ROHS3 compliance and REACH unaffected status, with similar regulatory certifications (CE approval). The NLDD-1200H supports comparable efficiency and maximum output current. Product selection between these alternatives should be based on product status and certification compliance.
Frequently Asked Questions (FAQ)
Q1: What are the primary criteria for substituting LDD-1200LS with NLDD-1200H?
A1: Substitution is determined by output current, topology, input/output voltage ranges, dimming capability, features, regulatory compliance, and package/mounting compatibility.
Q2: Are the mounting types the same between LDD-1200LS and NLDD-1200H?
A2: No, the LDD-1200LS uses surface mount (24-SMD Module, 18 Leads), while the NLDD-1200H is through hole (24-DIP Module, 9 Leads).
Q3: Is there a difference in product status between the parts?
A3: The LDD-1200LS is obsolete; the NLDD-1200H is active.
Q4: Are the substitute models certified for CE and RoHS compliance?
A4: Both LDD-1200LS and NLDD-1200H carry CE approval and are ROHS3 compliant.
Q5: Can both drivers operate under similar environmental conditions?
A5: Both operate at -40°C minimum. LDD-1200LS reaches up to +71°C; NLDD-1200H up to +50°C.
Q6: Is there a difference in dimming capabilities?
A6: The LDD-1200LS supports both analog and PWM dimming. The NLDD-1200H supports PWM dimming.
Q7: Do both modules have remote on/off and short circuit protection features?
A7: Yes, both parts include remote on/off and short circuit protection. NLDD-1200H additionally features overvoltage protection.
Q8: What considerations are required for packaging and lead configuration?
A8: The package and lead configuration differ: confirm physical compatibility before substitution.
