Key Parameters

Substitute Part Grouping Explanation

Substitute parts are selected strictly using the following parameters:

• Type: Constant Current
• Topology: Buck
• Number of Outputs: 1
• Voltage - Input (Min and Max)
• Voltage - Output Range
• Current - Output (Max)
• Power (Watts)
• Dimming Method
• Features
• Operating Temperature
• Efficiency
• Approval/Certification
• Compliance (RoHS, REACH)
• Mounting Type, Package / Case, and Size / Dimension for mechanical compatibility

Only parts matching the above electrical and mechanical specification ranges are listed as substitutes.

Parameter Comparison

Engineering Selection Recommendations

Selection is based on the main part's Obsolete status and substitute part's Active status. Both the main part and substitute part are ROHS3 Compliant, REACH Unaffected, and have an MSL of 1 (Unlimited). Both devices are categorized as EAR99 for export and have the same HTSUS code. Approval agency coverage and packaging dimensions should be compared per application requirements, especially mechanical mounting type and package/case specifications.

Frequently Asked Questions (FAQ)

Q: What are the key substitution parameters for LED driver modules in this category?
A: Key substitution parameters include constant current type, buck topology, number of outputs, matching input/output voltage and current ranges, power rating, dimming method, approval agency, operating temperature, efficiency, compliance statuses, mounting type, package/case, and physical dimensions.

Q: Can the surface mount substitute part (RCD-24-0.35/PL/A-R) directly replace a through-hole module (VLD25-350-DIP)?
A: Mounting type and package/case differences must be considered for direct replacement. Through-hole and surface-mount modules use different installation methods on PCBs.

Q: Is certification coverage identical between these parts?
A: VLD25-350-DIP lists CE, EN, IEC approvals. RCD-24-0.35/PL/A-R lists EN approval. When certification standards are critical for the application, match based on the documented approval agencies.

Q: Does the substitute part provide the same remote on/off and short circuit protection features?
A: Both parts list remote on/off and short circuit protection (SCP). The substitute also includes OTP (over temperature protection).

Q: Are both devices compliant with RoHS3 and REACH?
A: Both VLD25-350-DIP and RCD-24-0.35/PL/A-R are ROHS3 Compliant and REACH Unaffected.

Q: How do package and size differences affect substitution?
A: Substitute part dimensions and mounting type should match mechanical constraints and board footprint requirements for successful replacement.

Q: Does the operating temperature range match between both parts?
A: Both devices support -40°C to 85°C operating temperature range.
