MP4054AGJ-Z Equivalent & Substitute Parts

Part Overview

The MP4054AGJ-Z is an AC DC offline switcher LED driver IC manufactured by Monolithic Power Systems. This single-output device operates in the 12V to 28V supply range and employs PWM dimming for lighting applications. The part is currently in active production status with 4581 units in stock. Alternative components may be required due to supply constraints, design optimization, or application-specific requirements such as dimming method compatibility or operating temperature ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MP4054AGJ-Z is determined by the following critical parameters:

Functional Compatibility:

• AC DC offline switcher topology with single output
• Support for step-down (buck) and step-up (boost) conversion modes
• LED driver application suitability

Electrical Compatibility:

• Supply voltage range overlap or containment (12V–28V for MP4054AGJ-Z)
• Switching frequency in the 4–5kHz range
• Dimming capability (PWM or alternative methods such as Triac)

Physical & Environmental Compatibility:

• Surface mount package with 8-pin configuration
• Operating temperature range of -40°C minimum
• RoHS3 compliance and MSL Level 1 rating

The substitute part AL1692S-13 (Diodes Incorporated) meets these criteria with the following considerations: it operates within a narrower supply voltage range (8.5V–20V), uses Triac dimming instead of PWM, and operates at 4kHz switching frequency. These differences define the scope of substitution applicability.

Parameter Comparison

Engineering Selection Recommendations

Both the MP4054AGJ-Z and AL1692S-13 are active production components with ROHS3 compliance and MSL Level 1 ratings, ensuring regulatory and environmental suitability for industrial and commercial lighting applications.

MP4054AGJ-Z Selection Criteria:

• Applications requiring PWM dimming control
• Supply voltage range of 12V to 28V
• Operating junction temperatures up to 125°C
• TSOT-23-8 package footprint compatibility

AL1692S-13 Selection Criteria:

• Applications requiring Triac dimming control
• Supply voltage range of 8.5V to 20V
• Operating ambient temperatures up to 105°C
• 8-SOIC package footprint compatibility
• Flyback topology support in addition to buck and boost modes

Package differences (TSOT-23-8 versus 8-SOIC) require PCB layout verification. Supply voltage range differences necessitate circuit design confirmation. Dimming method differences (PWM versus Triac) require application-level compatibility assessment.

Frequently Asked Questions (FAQ)

Q: Can AL1692S-13 directly replace MP4054AGJ-Z in all applications?

A: No. The AL1692S-13 operates within a narrower supply voltage range (8.5V–20V versus 12V–28V), uses Triac dimming instead of PWM, and has a lower maximum operating temperature (105°C versus 125°C). Substitution is valid only when the application operates within the AL1692S-13 electrical and thermal specifications.

Q: What are the package compatibility implications?

A: MP4054AGJ-Z uses TSOT-23-8 (SOT-23-8 Thin) packaging, while AL1692S-13 uses 8-SOIC (0.154", 3.90mm Width) packaging. These are not pin-compatible footprints. PCB redesign is required for substitution.

Q: How do the dimming methods differ?

A: MP4054AGJ-Z employs PWM (Pulse Width Modulation) dimming, which modulates the duty cycle of the switching signal. AL1692S-13 uses Triac dimming, which is a phase-control method. These require different control circuit implementations and are not interchangeable without application redesign.

Q: Are both parts suitable for the same temperature range?

A: No. MP4054AGJ-Z operates from -40°C to 125°C (junction temperature), while AL1692S-13 operates from -40°C to 105°C (ambient temperature). Applications requiring operation above 105°C ambient or 125°C junction temperature must use MP4054AGJ-Z.

Q: What compliance certifications apply to both parts?

A: Both components are ROHS3 compliant, REACH unaffected, and carry MSL Level 1 (unlimited moisture sensitivity). Both are classified under ECCN EAR99 and HTSUS 8542.39.0001.
