Key Parameters

Substitute Part Grouping Explanation

Substitute parts are identified based on the following key parameters: current regulation mode (constant current), topology (buck), output current capability, input and output voltage ranges, dimming control, protective features, temperature range, efficiency, mounting type, package/case form factor, compliance statuses, and approvals. This approach ensures that any listed substitute provides equivalent electrical performance and meets operational and certification requirements defined by the original device.

Key parameters for substitution compatibility:

• Type: Constant Current
• Topology: Buck
• Number of Outputs: 1
• Input Voltage Range
• Output Voltage Range
• Maximum Output Current
• Dimming Capability: PWM
• Protection Features
• Efficiency
• Mounting Type
• Package/Case
• Regulatory Compliance and Certification

Parameter Comparison

Engineering Selection Recommendations

The LDD-1000HS is classified as obsolete, while the NLDD-1050H is listed as active with RoHS and REACH compliance. Both parts have similar key regulatory statuses and approval agencies. The main difference in mechanical design is the mounting type and package/case style. Compliance with required certifications such as CE is ensured for both products.

Frequently Asked Questions (FAQ)

Q1: What criteria are used for selecting equivalent and substitute parts for the LDD-1000HS?
A1: Only parameters explicitly provided, such as current regulation type, topology, output current and voltage ratings, input voltage range, dimming, features, efficiency, mounting type, package, and product compliance are used for selection.

Q2: Is the NLDD-1050H functionally compatible with the LDD-1000HS?
A2: NLDD-1050H is a constant current, buck topology LED driver with similar electrical ratings and features corresponding to the original part. Differences in packaging and mounting type are present.

Q3: How does the mounting type differ between these models?
A3: LDD-1000HS uses a surface mount package, while NLDD-1050H uses a through-hole package. This difference affects mechanical fit and assembly processes.

Q4: Do both parts meet the same compliance and approval standards?
A4: Both models are ROHS3 Compliant, REACH Unaffected, and have the same ECCN and HTSUS codes. Both have CE certification.

Q5: Can substitutes be selected on the basis of package size and type?
A5: Package type and mounting method are included as criteria in the substitution process and must be matched according to design requirements.

Q6: Is efficiency the same for both parts?
A6: Both LDD-1000HS and NLDD-1050H list an efficiency of 96%.
