Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TS19706CS RLG are selected based on functional equivalence within the AC DC offline switcher LED driver category. The primary substitution criteria are:

Core Functional Parameters:

• Product Type: AC DC Offline Switcher LED Driver IC
• Number of Outputs: 1
• Applications: Lighting
• Mounting Type: Surface Mount
• RoHS Compliance: ROHS3 Compliant

Electrical Operating Parameters:

• Supply voltage range compatibility
• Internal switching capability
• Topology support (Flyback, Buck, Boost configurations)
• Operating temperature range

Physical Parameters:

• Surface mount packaging
• Pin count and package form factor

Substitute parts identified include devices from Microchip Technology, Texas Instruments, Analog Devices Inc., and Monolithic Power Systems Inc. These substitutes maintain active product status and provide equivalent or enhanced functionality for LED driver applications. All substitute parts are ROHS3 compliant and suitable for lighting applications.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements equivalent to the TS19706CS RLG. The following selection criteria apply based on product status and compliance:

Active Product Status Advantage: All substitute parts listed (HV9922N8-G, LM3445MMX/NOPB, LT3799EMSE-1#PBF, MP4088GJ-P, TPS92210D) maintain active product status with established supply chain availability. This contrasts with the obsolete status of the TS19706CS RLG and ensures long-term component availability for production continuity.

Compliance and Certification: All substitute parts are ROHS3 compliant and REACH unaffected, maintaining regulatory alignment with the original component. Moisture sensitivity levels for all active substitutes are rated at MSL 1 (Unlimited), providing superior handling and storage characteristics compared to the TS19706CS RLG MSL 3 rating.

Topology and Functional Considerations:

• TPS92210D provides the closest package compatibility (8-SOIC) and Flyback topology matching, with supply voltage range of 9V to 20V
• LT3799EMSE-1#PBF offers Flyback topology with enhanced operating temperature range (-40°C to 125°C) and 16-MSOP-EP packaging
• HV9922N8-G supports Buck topology with extended supply voltage range (20V to 400V) and SOT-89-3 packaging
• LM3445MMX/NOPB provides Buck topology with narrow supply voltage range (8V to 12V) and 10-VSSOP packaging
• MP4088GJ-P supports Buck and Boost topologies with low supply voltage range (4.5V to 5V) and compact TSOT-23-5 packaging

Supply Chain Availability: Inventory levels for active substitutes range from 1,068 to 25,400 units, providing established supply chain presence compared to the 756 units of the obsolete TS19706CS RLG.

Frequently Asked Questions (FAQ)

Q: Why is the TS19706CS RLG classified as obsolete? A: The TS19706CS RLG has reached end-of-life status with Taiwan Semiconductor Corporation. All identified substitute parts maintain active product status with established manufacturers, ensuring continued availability and support for new designs and production requirements.

Q: What is the primary difference between the TS19706CS RLG and its substitutes? A: The TS19706CS RLG supports multiple topologies (Flyback, Buck, Boost) with internal switching and operates across a 7.8V to 33V supply range. Substitute parts are specialized for specific topologies: TPS92210D and LT3799EMSE-1#PBF for Flyback applications, HV9922N8-G and LM3445MMX/NOPB for Buck applications, and MP4088GJ-P for Buck/Boost applications. Selection depends on the specific topology required in the target application.

Q: Are all substitute parts pin-compatible with the TS19706CS RLG? A: No. The TS19706CS RLG uses 8-SOP packaging. TPS92210D also uses 8-SOIC packaging with identical physical dimensions (0.154", 3.90mm Width), providing direct package compatibility. Other substitutes use different package types (SOT-89-3, 10-VSSOP, 16-MSOP-EP, TSOT-23-5) and require PCB layout modifications. Pin configuration and functionality differ across all parts and must be verified against specific application requirements.

Q: What is the significance of the MSL (Moisture Sensitivity Level) difference? A: The TS19706CS RLG has MSL 3 (168 Hours), requiring controlled moisture exposure during storage and handling. All substitute parts have MSL 1 (Unlimited), eliminating moisture sensitivity constraints and reducing handling complexity during manufacturing and assembly processes.

Q: Can I use any substitute part as a direct replacement? A: Direct replacement depends on application-specific requirements. TPS92210D offers the closest compatibility with matching 8-SOIC package and Flyback topology. Other substitutes require circuit design modifications to accommodate different topologies, supply voltage ranges, and package configurations. Application circuit requirements must be evaluated against each substitute's electrical specifications.

Q: What supply voltage ranges are supported by the substitutes? A: Supply voltage ranges vary significantly: TS19706CS RLG (7.8V to 33V), HV9922N8-G (20V to 400V), LM3445MMX/NOPB (8V to 12V), MP4088GJ-P (4.5V to 5V), TPS92210D (9V to 20V). Selection must match the target application's power supply specifications.

Q: Do all substitutes support Triac dimming? A: All identified substitute parts support Triac dimming capability. The TS19706CS RLG dimming specification is not provided in the available data. If dimming functionality is required, all substitutes provide this feature for lighting applications.

Q: What is the operating temperature range difference? A: The TS19706CS RLG operates from -40°C to 85°C (TA). Substitute parts from Texas Instruments and Analog Devices (LM3445MMX/NOPB, LT3799EMSE-1#PBF, MP4088GJ-P, TPS92210D) extend the upper operating temperature to 125°C (TJ), providing enhanced thermal performance for demanding lighting applications.

Q: Are all substitutes ROHS3 compliant? A: Yes. All identified substitute parts are ROHS3 compliant and REACH unaffected, maintaining regulatory alignment with the TS19706CS RLG for environmental and hazardous substance restrictions.
