Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MP3363GJ-Z is determined by strict equivalence across the following critical parameters:

Electrical Specifications:

• Supply voltage range: 1.8V minimum to 36V maximum
• Output voltage range: 0.2V to 36V
• Operating frequency: 200kHz to 2.2MHz
• Dimming capability: Analog and PWM control
• Single output configuration
• Step-up (boost) topology with internal switching element

Mechanical & Packaging Requirements:

• Package type: SOT-23-8 Thin (TSOT-23-8)
• Surface mount mounting type
• Supplier device package: TSOT-23-8

Compliance & Environmental:

• RoHS3 compliance
• Moisture sensitivity level 1
• Operating temperature range: -40°C to 125°C

Application Domain:

• Backlight LED driver applications

Substitute parts must match all parameters listed above. Deviations in any electrical specification, package type, or compliance certification disqualify a part from substitution eligibility.

Engineering Selection Recommendations

MP3363GJ-P as Direct Substitute:

The MP3363GJ-P is a parametric equivalent to the MP3363GJ-Z. Both parts share identical electrical specifications, package configuration, and compliance certifications. The distinction between these part numbers relates to packaging format: MP3363GJ-Z is supplied in Tape & Reel format, while MP3363GJ-P is also supplied in Tape & Reel format according to the provided specifications.

Both parts are active products with current manufacturing status. Selection between MP3363GJ-Z and MP3363GJ-P should be based on:

1. Inventory Availability: MP3363GJ-Z has 4003 units in stock; MP3363GJ-P has 2548 units in stock.
2. Supply Chain Requirements: Both parts meet identical electrical and mechanical requirements for backlight LED driver applications.
3. Compliance Certification: Both parts are ROHS3 compliant, REACH unaffected, and carry identical environmental classifications.

No electrical redesign, PCB layout modification, or firmware adjustment is required when substituting between these parts.

Frequently Asked Questions (FAQ)

Q: Can MP3363GJ-P replace MP3363GJ-Z in production designs?

A: Yes. The MP3363GJ-P is a direct parametric equivalent. All electrical specifications, package dimensions, pin configurations, and compliance certifications are identical. No circuit modifications are required.

Q: Are there differences in the TSOT-23-8 package between these parts?

A: No. Both parts use the SOT-23-8 Thin package (TSOT-23-8) with identical supplier device packaging specifications. Pin-to-pin compatibility is guaranteed.

Q: Do both parts support the same dimming control methods?

A: Yes. Both MP3363GJ-Z and MP3363GJ-P support analog and PWM dimming control with identical frequency ranges (200kHz to 2.2MHz).

Q: What is the difference between the part numbers if they are equivalent?

A: The part number suffix difference (Z versus P) reflects internal Monolithic Power Systems Inc. product designation. This does not indicate functional, electrical, or mechanical differences. Both parts are manufactured to the same specifications.

Q: Are there any temperature or voltage rating differences?

A: No. Both parts operate across the identical temperature range (-40°C to 125°C junction temperature) and support the same supply voltage range (1.8V to 36V) and output voltage range (0.2V to 36V).

Q: Which part should be selected for new designs?

A: Either part is suitable for new designs. Selection should be based on supplier availability, lead time, and inventory status. Both parts carry active product status and are supported by Monolithic Power Systems Inc.

Q: Are moisture sensitivity or RoHS compliance different between these parts?

A: No. Both parts carry MSL 1 (unlimited moisture sensitivity level) and are ROHS3 compliant. Environmental and handling requirements are identical.
