Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MP3362GJ-P are classified into two categories based on electrical and mechanical compatibility:

Parametric Equivalents share identical electrical specifications, output topology, dimming functionality, and package type. These parts are direct functional replacements with no design modifications required:

• Supply voltage range: 3V to 36V
• Output voltage: 36V
• Output current: 4A per channel
• Topology: Step-Up (Boost)
• Dimming: Analog and PWM capable
• Package: TSOT-23-8 surface mount
• Operating temperature: -40°C to 125°C

Similar Parts provide comparable LED driver functionality but differ in one or more critical parameters such as output current rating, supply voltage range, package type, or number of outputs. These parts require design evaluation before substitution.

Engineering Selection Recommendations

Parametric Equivalents (Direct Substitutes)

MP3362GJ-Z, MPQ3362GJ-AEC1-P, and MPQ3362GJ-AEC1-Z are parametric equivalents of the MP3362GJ-P. These parts maintain identical electrical specifications across all critical parameters: 3V to 36V supply range, 36V output voltage, 4A output current, step-up boost topology, analog and PWM dimming capability, and TSOT-23-8 package configuration. The primary difference is packaging format: MP3362GJ-Z and MPQ3362GJ-AEC1-Z are supplied in Cut Tape and Digi-Reel format, while MP3362GJ-P and MPQ3362GJ-AEC1-P are supplied in Tape & Reel format. All four parts are ROHS3 compliant with MSL 1 rating and active product status. Selection between these equivalents is determined by packaging and supply chain requirements rather than electrical performance.

Similar Parts (Design Evaluation Required)

LM3410YMFE/NOPB (Texas Instruments) provides LED driver functionality with step-up boost topology and PWM dimming. However, this part differs in supply voltage range (2.7V to 5.5V versus 3V to 36V), output voltage capability (3V to 24V versus 36V), output current (2.8A switch current versus 4A), package type (SOT-23-5 versus TSOT-23-8), and dimming support (PWM only versus analog and PWM). This part is suitable for lower-voltage backlight applications but does not provide equivalent performance for 36V output applications.

LT3498EDDB#TRMPBF (Analog Devices Inc.) is a step-up boost LED driver with analog and PWM dimming. This part differs significantly in output current capability (20mA versus 4A), supply voltage range (2.5V to 12V versus 3V to 36V), output voltage (32V versus 36V), package type (12-DFN versus TSOT-23-8), and operating temperature range (-40°C to 85°C versus -40°C to 125°C). This part is designed for low-current LED applications and is not suitable for 4A output current requirements.

TPS92662QPHPRQ1 (Texas Instruments) is a multi-output LED driver with 12 independent outputs, PWM dimming, and automotive AEC-Q100 qualification. This part differs in output count (12 versus 1), package type (48-HTQFP versus TSOT-23-8), supply voltage range (4.5V to 60V), output voltage (62V), and moisture sensitivity level (MSL 3 versus MSL 1). This part is designed for automotive multi-channel LED applications and requires significant design changes for single-output applications.

All similar parts are ROHS3 compliant and active products. Selection of similar parts requires detailed design evaluation to confirm compatibility with application requirements.

Frequently Asked Questions (FAQ)

Q: Can MP3362GJ-Z be used as a direct replacement for MP3362GJ-P?

A: Yes. MP3362GJ-Z is a parametric equivalent with identical electrical specifications. The difference is packaging format: MP3362GJ-Z is supplied in Cut Tape and Digi-Reel format, while MP3362GJ-P is supplied in Tape & Reel format. Both parts are TSOT-23-8 surface mount packages with identical pin configurations and electrical performance.

Q: What is the difference between MP3362GJ-P and MPQ3362GJ-AEC1-P?

A: Both parts are parametric equivalents with identical electrical specifications and TSOT-23-8 packaging. The MPQ series designation indicates automotive-grade qualification (AEC-Q100 level). Both parts operate across 3V to 36V supply range with 4A output current and analog/PWM dimming. Selection depends on automotive qualification requirements for the application.

Q: Can LM3410YMFE/NOPB replace MP3362GJ-P in a 36V output application?

A: No. LM3410YMFE/NOPB has a maximum output voltage of 24V, which is insufficient for 36V output requirements. Additionally, the supply voltage range (2.7V to 5.5V) is narrower than MP3362GJ-P (3V to 36V), and output current capability is lower (2.8A versus 4A). This part is not suitable for this application.

Q: What are the packaging differences between the substitute parts?

A: MP3362GJ-P and MPQ3362GJ-AEC1-P are supplied in Tape & Reel (TR) format. MP3362GJ-Z and MPQ3362GJ-AEC1-Z are supplied in Cut Tape (CT) and Digi-Reel format. LM3410YMFE/NOPB uses SOT-23-5 package (5-pin). LT3498EDDB#TRMPBF uses 12-DFN package. TPS92662QPHPRQ1 uses 48-HTQFP package. Only the first four parts use TSOT-23-8 package and are pin-compatible.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed parts are ROHS3 compliant. However, TPS92662QPHPRQ1 has MSL 3 (168 hours) moisture sensitivity versus MSL 1 (unlimited) for other parts, which affects storage and handling requirements.

Q: Which substitute parts support both analog and PWM dimming?

A: MP3362GJ-Z, MPQ3362GJ-AEC1-P, MPQ3362GJ-AEC1-Z, and LT3498EDDB#TRMPBF support both analog and PWM dimming. LM3410YMFE/NOPB supports PWM dimming only. TPS92662QPHPRQ1 supports PWM dimming only.

Q: Can TPS92662QPHPRQ1 be used for single-output LED driver applications?

A: TPS92662QPHPRQ1 is designed for 12-output LED driver applications with 48-HTQFP packaging. While it provides PWM dimming capability, using this part for single-output applications would require significant design changes and would not be cost-effective. This part is not recommended for single-output applications.

Q: What is the operating temperature range difference between MP3362GJ-P and LT3498EDDB#TRMPBF?

A: MP3362GJ-P operates from -40°C to 125°C (junction temperature). LT3498EDDB#TRMPBF operates from -40°C to 85°C (junction temperature). The LT3498 has a narrower upper temperature limit, which may be a constraint in high-temperature applications.
