CL1N8-G LED Driver IC Equivalent & Substitute Parts

Part Overview

The CL1N8-G is a linear LED driver IC manufactured by Microchip Technology, designed for single-output LED applications with 20mA output current capability. This TO-243AA surface mount device operates across a wide supply voltage range of 5V to 90V and is actively produced with full RoHS3 compliance. Substitute parts are identified when equivalent functional performance can be achieved within the allowed electrical and mechanical parameters of this product category, accounting for differences in output current, supply voltage range, package type, and dimming capability.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CL1N8-G are identified based on the following substitution criteria:

Primary Substitution Parameters:

• Linear topology with single output configuration
• Surface mount packaging (alternative packages acceptable)
• Active product status with current manufacturing
• RoHS3 compliance and REACH unaffected status
• Operating temperature range compatibility or superior range
• Output current capability equal to or greater than 20mA

Substitution Logic: The CL1N8-G operates across 5V to 90V supply voltage with 20mA output current. Substitute parts may operate within different supply voltage ranges provided they support the application requirements. Output current capability must meet or exceed 20mA. Package differences (TO-243AA vs. 8-SOIC vs. SOT-25 vs. 8-SOP) are acceptable as long as surface mount technology is maintained and board layout can accommodate the alternative footprint.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active product status with full RoHS3 compliance and REACH unaffected certification, meeting regulatory requirements equivalent to the CL1N8-G.

APS13568ELJATR (Allegro MicroSystems): This substitute operates within a narrower supply voltage range (7V to 24V) compared to the CL1N8-G (5V to 90V). Output current capability is 150mA, exceeding the 20mA requirement. Operating temperature range is -40°C to 85°C. Moisture sensitivity level is MSL 3, requiring controlled storage conditions. Package is 8-SOIC-EP, differing from the original TO-243AA footprint.

PAM2800AABR (Diodes Incorporated): This substitute operates within a restricted supply voltage range (3.7V to 5.5V), limiting applicability to low-voltage systems. Output current capability is 350mA, significantly exceeding the 20mA requirement. Operating temperature range is -40°C to 85°C. Moisture sensitivity level is MSL 1 (unlimited). Package is SOT-25, differing from the original TO-243AA footprint.

R2A20134SP#W5 (Renesas Electronics Corporation): This substitute operates within a supply voltage range of 8.5V to 24V. Output current is not specified in the provided parameters. Operating temperature range is -40°C to 150°C, exceeding the CL1N8-G specification. Moisture sensitivity level is MSL 1 (unlimited). Package is 8-SOP, differing from the original TO-243AA footprint. Internal switch configuration differs (no internal switch vs. yes for CL1N8-G).

Frequently Asked Questions (FAQ)

Q: Can APS13568ELJATR replace CL1N8-G in all applications?

A: APS13568ELJATR is suitable for applications where the supply voltage range of 7V to 24V is compatible with system requirements. The CL1N8-G supports 5V to 90V, providing broader voltage compatibility. Output current capability of 150mA exceeds the 20mA requirement. Package footprint differs (8-SOIC-EP vs. TO-243AA), requiring PCB layout modification. Moisture sensitivity level MSL 3 requires controlled storage and handling.

Q: What are the supply voltage limitations of PAM2800AABR?

A: PAM2800AABR operates within 3.7V to 5.5V supply voltage range, restricting use to low-voltage applications. The CL1N8-G supports 5V to 90V, making it suitable for higher voltage systems. PAM2800AABR is not a suitable substitute for applications requiring supply voltages above 5.5V.

Q: How does R2A20134SP#W5 differ in internal architecture?

A: R2A20134SP#W5 features no internal switch, whereas CL1N8-G includes an internal switch. This architectural difference may affect circuit design and external component requirements. Operating temperature range of R2A20134SP#W5 extends to 150°C, exceeding CL1N8-G specification of 125°C.

Q: Are package differences critical for substitution?

A: Package differences require PCB layout modification. CL1N8-G uses TO-243AA (SOT-89), while substitutes use 8-SOIC-EP, SOT-25, or 8-SOP packages. Footprint, pin pitch, and thermal characteristics differ. Board redesign may be necessary to accommodate alternative packages.

Q: What is the significance of moisture sensitivity level differences?

A: CL1N8-G and PAM2800AABR have MSL 1 (unlimited moisture sensitivity), allowing standard storage conditions. APS13568ELJATR has MSL 3 (168 hours), requiring controlled humidity storage and baking procedures before reflow soldering. R2A20134SP#W5 has MSL 1 (unlimited). MSL rating affects component handling, storage, and manufacturing processes.

Q: Which substitute provides the widest operating temperature range?

A: R2A20134SP#W5 operates from -40°C to 150°C, providing the widest temperature range. CL1N8-G operates from -40°C to 125°C. APS13568ELJATR and PAM2800AABR both operate from -40°C to 85°C, the most restrictive range among all parts listed.
