Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the XC9401C60CSR-G are identified based on the following critical parameters that determine functional compatibility:

Primary Substitution Criteria:

• Type: AC DC Offline Switcher
• Number of Outputs: 1 Output
• Applications: Lighting
• Mounting Type: Surface Mount
• RoHS Compliance: ROHS3 Compliant
• Dimming Capability: PWM or Triac dimming support

Secondary Compatibility Factors:

• Operating temperature range overlap with -40°C minimum
• Supply voltage range compatibility or overlap
• Topology compatibility (Flyback, Step-Down Buck, or Step-Up Boost configurations)
• Package form factor suitable for surface mount assembly

The substitute parts listed below satisfy the core functional requirements of an AC DC offline LED driver IC with single output configuration. Variations in topology (inclusion of Step-Up Boost), dimming method (Triac vs. PWM), package type, and supply voltage ranges reflect design flexibility within the LED driver category while maintaining core application compatibility for lighting systems.

Engineering Selection Recommendations

Active Status Substitutes (Recommended for New Designs):

The following parts maintain Active product status and are suitable for immediate implementation:

• MP4054AGJ-P: Active status with unlimited MSL. Supports PWM dimming matching the original XC9401C60CSR-G dimming method. Extended operating temperature to 125°C (TJ). Supply voltage range 12V to 28V encompasses the original 9V to 15V specification. TSOT-23-8 package requires PCB layout modification from the original SOT-25-5.

• MP4068GN-Z: Active status with high inventory availability (83,080 pcs). Supports Triac dimming for alternative control schemes. Supply voltage range 4.1V to 5V with 50V output and 160mA current specification. 8-SOIC-EP package differs from original SOT-25-5 footprint.

• CPC9909NE: Active status with unlimited MSL. Supports PWM dimming. Extended supply voltage range 8V to 550V provides broad compatibility. Step-Down (Buck) and Step-Up (Boost) topology offers design flexibility. 8-SOIC-EP package requires footprint redesign.

Last Time Buy Status Substitutes (Limited Availability):

• TPS92001DGKR: Last Time Buy status with 55,100 pcs inventory. Supports Triac dimming. Topology matches original (Flyback, Step-Down Buck). Supply voltage maximum 21V. 8-VSSOP package differs from original SOT-25-5.

• TPS92002D: Last Time Buy status with 1,288 pcs inventory. Supports Triac dimming. Topology matches original (Flyback, Step-Down Buck). Supply voltage maximum 21V. Operating temperature range -40°C to 85°C matches original. 8-SOIC package requires footprint modification.

Compliance Verification:

All substitute parts maintain ROHS3 compliance and REACH Unaffected status, consistent with the original XC9401C60CSR-G. All parts are classified under HTSUS 8542.39.0001 and ECCN EAR99.

Frequently Asked Questions (FAQ)

Q: Why is the XC9401C60CSR-G obsolete, and what are the implications?

A: The XC9401C60CSR-G is classified as obsolete by the manufacturer. This designation indicates the part is no longer in production and future availability cannot be guaranteed. Existing inventory may be limited. Designs currently using this part should transition to active-status alternatives to ensure long-term supply chain continuity.

Q: What is the primary difference between PWM and Triac dimming in these LED driver substitutes?

A: PWM (Pulse Width Modulation) dimming controls LED brightness by varying the duty cycle of the switching signal. Triac dimming uses phase-angle control compatible with AC line dimming circuits. The XC9401C60CSR-G uses PWM dimming. Substitutes using Triac dimming (MP4032-2GS, MP4068GN-Z, TPS92001DGKR, TPS92002D) require different control circuitry and are suitable for applications requiring AC line dimming compatibility.

Q: Can I directly replace the XC9401C60CSR-G with MP4054AGJ-P without PCB modifications?

A: No. The XC9401C60CSR-G uses SOT-25-5 packaging, while MP4054AGJ-P uses TSOT-23-8 packaging. These packages have different pin configurations and footprints. PCB layout redesign is required. However, MP4054AGJ-P maintains PWM dimming functionality and operates within compatible voltage ranges (12V to 28V supply).

Q: Which substitute offers the closest topology match to the original XC9401C60CSR-G?

A: TPS92001DGKR and TPS92002D both use Flyback and Step-Down (Buck) topology, identical to the original XC9401C60CSR-G. However, both are Last Time Buy status parts with limited future availability. TPS92002D offers unlimited MSL (1) and operating temperature range matching the original (-40°C to 85°C TA).

Q: What is Moisture Sensitivity Level (MSL), and why does it matter?

A: MSL indicates the maximum time a component can be exposed to ambient conditions (typically 30°C, 85% relative humidity) before soldering. MSL 1 (Unlimited) means no time restriction. MSL 2 (1 Year) requires soldering within one year of package opening. MSL 2A (4 Weeks) requires soldering within four weeks. Higher MSL values require more careful handling and storage protocols.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed (CPC9909NE, MP4032-2GS, MP4054AGJ-P, MP4068GN-Z, TPS92001DGKR, TPS92002D) are ROHS3 Compliant and REACH Unaffected, matching the compliance status of the original XC9401C60CSR-G.

Q: What supply voltage range should I consider when selecting a substitute?

A: The original XC9401C60CSR-G operates with 9V to 15V supply. MP4054AGJ-P (12V to 28V) and CPC9909NE (8V to 550V) both encompass this range. MP4068GN-Z operates at 4.1V to 5V, which does not overlap with the original specification. TPS92001DGKR and TPS92002D specify maximum 21V supply voltage. Verify your application's actual supply voltage requirements before selection.

Q: Can I use MP4068GN-Z as a direct substitute for the XC9401C60CSR-G?

A: No. MP4068GN-Z operates at 4.1V to 5V supply voltage, which does not overlap with the original 9V to 15V specification. Additionally, MP4068GN-Z uses Triac dimming instead of PWM dimming. This part is suitable only for applications with 4.1V to 5V supply and Triac dimming requirements.

Q: What is the difference between operating temperature specifications (TA vs. TJ)?

A: TA refers to ambient temperature, measured at the component's external environment. TJ refers to junction temperature, measured at the semiconductor die itself. TA specifications are typically more conservative. The original XC9401C60CSR-G specifies -40°C to 85°C TA. Substitutes specifying TJ may operate at higher junction temperatures under the same ambient conditions.
