NLSF595DTR2 LED Driver IC - Equivalent & Substitute Parts

Part Overview

The NLSF595DTR2 is an 8-output linear LED driver IC manufactured by onsemi, housed in a 16-TSSOP surface mount package. This device is designed for LED dimming applications with a 12mA output current per channel and operates across a 2V to 5.5V supply voltage range. The part is currently classified as obsolete, making identification of suitable substitutes essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the NLSF595DTR2 is evaluated based on the following critical parameters:

Direct Substitutes must maintain:

• 8 output channels
• Linear topology with internal switching capability
• Compatible supply voltage range (minimum 2V, maximum 5.5V)
• Output current capability of at least 12mA per channel
• Surface mount packaging with compatible footprint dimensions
• Operating temperature range covering -55°C to 125°C

Similar Substitutes may accommodate:

• Higher output current capability (120mA vs. 12mA)
• Different package types (20-VQFN vs. 16-TSSOP)
• Modified supply voltage minimums (3V vs. 2V)
• Reduced operating temperature range (-40°C to 85°C vs. -55°C to 125°C)
• Additional integrated features (25MHz frequency capability)

These variations require design review to confirm compatibility with the target application.

Engineering Selection Recommendations

NLSF595DTR2G (Direct Substitute - Recommended)

The NLSF595DTR2G is the primary substitute for the obsolete NLSF595DTR2. Both parts share identical electrical specifications, package dimensions, and thermal operating range. The NLSF595DTR2G maintains active product status with onsemi and achieves ROHS3 compliance, addressing regulatory requirements for new designs. Packaging is available in Tape & Reel format with 9,151 units in stock. This part requires no design modifications and provides direct pin-for-pin compatibility.

TLC59108IRGYR (Similar Substitute - Design Review Required)

The TLC59108IRGYR from Texas Instruments offers an alternative 8-output linear LED driver with significantly higher output current capability (120mA vs. 12mA per channel) and elevated output voltage (17V vs. 5.5V). This part is suitable for applications requiring higher power delivery. However, substitution requires design verification due to: package change from 16-TSSOP to 20-VQFN, minimum supply voltage increase from 2V to 3V, reduced operating temperature range (-40°C to 85°C), and increased moisture sensitivity (MSL 2). The TLC59108IRGYR is actively produced by Texas Instruments with 130,051 units available.

Frequently Asked Questions (FAQ)

Q: Can NLSF595DTR2G be used as a direct replacement for NLSF595DTR2?

A: Yes. The NLSF595DTR2G is a direct substitute with identical electrical and mechanical specifications. Both parts feature 8 outputs, 12mA per channel, 16-TSSOP packaging, and -55°C to 125°C operating range. The primary difference is product status (active vs. obsolete) and RoHS compliance (ROHS3 vs. non-compliant).

Q: What are the key differences between NLSF595DTR2G and TLC59108IRGYR?

A: The TLC59108IRGYR provides 10 times higher output current (120mA vs. 12mA) and higher output voltage (17V vs. 5.5V), but uses a different package (20-VQFN vs. 16-TSSOP), requires minimum 3V supply (vs. 2V), and operates over a narrower temperature range (-40°C to 85°C vs. -55°C to 125°C).

Q: Is the TLC59108IRGYR compatible with existing PCB layouts designed for NLSF595DTR2?

A: No. The TLC59108IRGYR uses a 20-pin VQFN package with different pin assignments and footprint dimensions compared to the 16-pin TSSOP package of the NLSF595DTR2. PCB redesign is required.

Q: What is the moisture sensitivity difference between these parts?

A: NLSF595DTR2 and NLSF595DTR2G both have MSL 1 (unlimited shelf life). TLC59108IRGYR has MSL 2, requiring storage at controlled humidity (≤60% RH) for up to 1 year after packaging.

Q: Are all three parts RoHS compliant?

A: NLSF595DTR2 is RoHS non-compliant. Both NLSF595DTR2G and TLC59108IRGYR are ROHS3 compliant, meeting current environmental regulations for new designs.
