LC5513D LED Driver IC Equivalent & Substitute Parts

Part Overview

The LC5513D is an AC DC offline switcher LED driver IC manufactured by Sanken Electric USA Inc., designed for single-output LED lighting applications. This 8-DIP through-hole component integrates an internal switch and operates across a supply voltage range up to 20V with an operating temperature range of -55°C to 125°C. The part is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing production requirements. Substitute parts must maintain functional compatibility as AC DC offline switcher LED drivers while accommodating different package types, topologies, and dimming capabilities.

Engineering Selection Recommendations

For Direct Through-Hole Replacement: No substitute parts maintain the 8-DIP through-hole package format. All listed substitutes are surface-mount devices. Direct PCB replacement requires redesign of the footprint and layout.

For Active Product Status: AL9910S-13, LM3445M/NOPB, MP4068GN-Z, NCL30188BDR2G, and UCC28810D are all active products with current manufacturing and availability. TPS92002D carries Last Time Buy status and should be avoided for new long-term production designs.

For Extended Temperature Range: LM3445M/NOPB and NCL30188BDR2G support the full -40°C to 125°C operating temperature range, matching or exceeding the LC5513D's -55°C to 125°C specification. AL9910S-13 and TPS92002D are limited to -40°C to 85°C.

For Supply Voltage Compatibility: AL9910S-13 (500V max), NCL30188BDR2G (25.5V max), and UCC28810D (18V max) support supply voltages at or near the LC5513D's 20V maximum. LM3445M/NOPB (12V max) and MP4068GN-Z (5V max) have reduced voltage ratings and are suitable only for lower-voltage applications.

For Compliance & Reliability: All substitute parts are ROHS3 compliant. AL9910S-13, LM3445M/NOPB, and UCC28810D maintain MSL 1 (Unlimited) moisture sensitivity, matching the LC5513D. NCL30188BDR2G carries MSL 3 (168 Hours), requiring controlled storage and handling.

For Internal Switch Configuration: UCC28810D is the only substitute with an integrated internal switch, matching the LC5513D's architecture. All other substitutes require external switch components, potentially increasing circuit complexity.

Frequently Asked Questions (FAQ)

Q: Can I use a surface-mount substitute directly on a through-hole PCB designed for the LC5513D?

A: No. The LC5513D uses an 8-DIP through-hole package, while all substitutes use 8-SOIC or 14-SOIC surface-mount packages. PCB redesign and layout modification are required. Alternatively, through-hole to surface-mount adapter boards can be used for prototyping, but are not recommended for production.

Q: Which substitute has the closest electrical specifications to the LC5513D?

A: UCC28810D offers the closest match with an internal switch, 18V maximum supply voltage (near the LC5513D's 20V), and -40°C to 105°C operating temperature. However, it requires surface-mount implementation.

Q: Are all substitutes RoHS compliant?

A: Yes. All listed substitutes are ROHS3 compliant, meeting current environmental and regulatory requirements equivalent to the LC5513D's RoHS compliance.

Q: What is the difference between parts with and without internal switches?

A: The LC5513D and UCC28810D include integrated internal switches, reducing external component count. Substitutes without internal switches (AL9910S-13, LM3445M/NOPB, MP4068GN-Z, NCL30188BDR2G, TPS92002D) require external switching components, increasing circuit complexity but offering greater design flexibility.

Q: Which substitute is best for high-temperature applications?

A: LM3445M/NOPB and NCL30188BDR2G both support -40°C to 125°C operating temperature. The LC5513D extends to -55°C minimum; no substitute fully matches this lower temperature limit.

Q: Can I use MP4068GN-Z or LM3445M/NOPB in a 20V supply application?

A: MP4068GN-Z has a 5V maximum supply rating and is unsuitable for 20V applications. LM3445M/NOPB has a 12V maximum rating and cannot be used at 20V. AL9910S-13, NCL30188BDR2G, and UCC28810D support 20V or higher supply voltages.

Q: What does MSL rating mean for component storage?

A: MSL (Moisture Sensitivity Level) indicates how long a component can be stored in standard conditions before moisture absorption affects solderability. MSL 1 (Unlimited) allows indefinite storage. MSL 3 (168 Hours) requires use within 168 hours of package opening. NCL30188BDR2G carries MSL 3 and requires controlled handling.

Q: Is TPS92002D a viable substitute for new production?

A: TPS92002D carries Last Time Buy status, indicating the manufacturer is discontinuing production. It is not recommended for new long-term production designs. Active alternatives include AL9910S-13, LM3445M/NOPB, MP4068GN-Z, NCL30188BDR2G, and UCC28810D.
