IX9907NTR LED Driver IC - Equivalent & Substitute Parts

Part Overview

The IX9907NTR is an active LED driver IC manufactured by IXYS Integrated Circuits Division, designed for AC/DC offline switching applications with flyback topology and triac dimming capability. This component is classified as a Power Management (PMIC) device and is currently in active production status with 1105 units in stock. The IX9907NTR serves lighting applications requiring offline switcher functionality with integrated triac dimming support. Substitute parts may be required due to supply constraints, design optimization, or application-specific performance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IX9907NTR is determined by the following critical parameters:

• Functional Category: Power Management (PMIC) - LED Driver IC
• Application Type: AC/DC Offline Switcher with Triac Dimming
• Number of Outputs: Single output configuration
• Dimming Capability: Triac dimming support
• Supply Voltage Range: Compatibility within specified input voltage window
• Mounting Type: Surface Mount
• Package Compatibility: Pin count and physical dimensions must accommodate PCB layout

The TPS92410D qualifies as a manufacturer-recommended substitute based on matching functional requirements: AC/DC offline switcher topology, single output, triac dimming capability, surface mount packaging, and active product status. Both devices support triac dimming and are designed for lighting applications.

Parameter Comparison

Engineering Selection Recommendations

Both the IX9907NTR and TPS92410D are active, ROHS3-compliant components suitable for LED driver applications. Selection between these parts should be based on the following factors:

IX9907NTR is appropriate when:

• Integrated internal switch functionality is required
• Operating temperature range up to 150°C is necessary
• MSL 1 (unlimited moisture sensitivity) is preferred for storage and handling
• 8-SOIC package footprint is specified in PCB design
• Supply voltage range of 10.5V to 40V matches application requirements

TPS92410D is appropriate when:

• Extended supply voltage range (9.5V to 450V) is required
• Analog dimming capability in addition to triac dimming is needed
• 13-SOIC package footprint can be accommodated in PCB layout
• Lower minimum supply voltage (9.5V) is beneficial
• MSL 2 handling requirements are acceptable

Both devices maintain active production status and full regulatory compliance (ROHS3, REACH Unaffected, EAR99 classification).

Frequently Asked Questions (FAQ)

Q: Can the TPS92410D directly replace the IX9907NTR without PCB modifications?

A: Package differences require PCB layout evaluation. The IX9907NTR uses 8-SOIC packaging while the TPS92410D uses 13-SOIC (14-SOIC with 13 leads). Pin assignments and footprint dimensions differ, necessitating schematic and layout review before substitution.

Q: What are the key functional differences between these two parts?

A: The IX9907NTR includes an integrated internal switch, while the TPS92410D does not. The TPS92410D offers extended supply voltage range (9.5V to 450V) compared to the IX9907NTR (10.5V to 40V). The TPS92410D supports both analog and triac dimming, whereas the IX9907NTR supports triac dimming only.

Q: Are both parts suitable for the same lighting applications?

A: Both are designed for AC/DC offline switcher lighting applications with triac dimming capability. Application suitability depends on specific supply voltage requirements, dimming control method, and thermal operating conditions. The IX9907NTR's higher maximum operating temperature (150°C vs. 125°C) may be advantageous in thermally constrained designs.

Q: What is the impact of different MSL ratings?

A: The IX9907NTR has MSL 1 (unlimited shelf life), while the TPS92410D has MSL 2 (1-year shelf life). This affects storage, handling, and reflow processing requirements. MSL 2 components require more stringent moisture control during manufacturing.

Q: Are there supply voltage compatibility concerns?

A: The IX9907NTR operates within 10.5V to 40V, while the TPS92410D operates within 9.5V to 450V. Applications using supply voltages below 10.5V or above 40V require the TPS92410D. Applications within the 10.5V to 40V window are compatible with both devices.
