MGSF1P02LT1 Equivalent & Substitute Parts

Part Overview

The MGSF1P02LT1 is a P-Channel MOSFET manufactured by onsemi, rated for 20V drain-to-source voltage with 750mA continuous drain current at 25°C. The device is housed in a SOT-23-3 (TO-236) surface mount package and is designed for low-power switching applications requiring compact form factors.

This part carries an Obsolete product status, making identification of functionally equivalent alternatives necessary for ongoing design support, production continuity, and component sourcing. Substitute parts must maintain electrical compatibility across critical parameters including voltage rating, current capacity, gate threshold characteristics, and thermal performance while accommodating the same or compatible package footprint.

Substitute Part Grouping Explanation

Substitute parts for the MGSF1P02LT1 are identified based on strict electrical and mechanical compatibility criteria. The following parameters establish the substitution basis:

Electrical Compatibility Requirements:

• FET Type: P-Channel topology
• Drain to Source Voltage (Vdss): 20V minimum rating
• Continuous Drain Current (Id): 750mA or greater at 25°C
• Gate Threshold Voltage (Vgs(th)): Maximum 2.4V @ 250µA or lower
• Maximum Gate Voltage (Vgs): ±12V or greater
• Power Dissipation: 400mW or greater thermal capacity
• Operating Temperature Range: -55°C to 150°C or equivalent

Mechanical Compatibility Requirements:

• Package Type: SOT-23-3 (TO-236-3, SC-59) surface mount
• Mounting Type: Surface mount
• Moisture Sensitivity Level: MSL 1 or equivalent

The IRLML6302TRPBF from Infineon Technologies satisfies these criteria with equivalent voltage and current ratings, compatible package designation, and matching thermal and temperature specifications. Both devices operate within the same SOT-23-3 footprint, enabling direct board-level substitution.

Engineering Selection Recommendations

MGSF1P02LT1 (onsemi) — Primary Part: The MGSF1P02LT1 is classified as Obsolete. This designation indicates the part is no longer in active production and may face supply constraints. The device carries RoHS non-compliant status, which may restrict use in applications subject to RoHS regulations.

IRLML6302TRPBF (Infineon Technologies) — Substitute Part: The IRLML6302TRPBF provides electrical and mechanical equivalence to the MGSF1P02LT1 across all critical parameters. The substitute part is rated for 780mA continuous drain current, exceeding the 750mA requirement of the primary part. Both devices share identical voltage ratings (20V Vdss), operating temperature range (-55°C to 150°C), and SOT-23-3 package footprint.

The IRLML6302TRPBF carries ROHS3 Compliant status, providing regulatory advantage for applications requiring RoHS adherence. The part is designated as Not For New Designs, indicating limited long-term availability; however, it remains a valid substitute for legacy system support and production continuity.

Selection Basis:

• Voltage and current ratings are equivalent or superior
• Package footprint is identical, enabling direct PCB substitution
• Thermal performance (540mW vs. 400mW) provides design margin
• Temperature operating range is identical
• Moisture sensitivity classification is equivalent
• RoHS compliance status differs; select based on regulatory requirements

Frequently Asked Questions (FAQ)

Q: Can the IRLML6302TRPBF directly replace the MGSF1P02LT1 on existing PCBs?

A: Yes. Both devices use the SOT-23-3 (TO-236-3) package with identical pin configuration and footprint. Direct board-level substitution is supported without layout modifications.

Q: What are the key electrical differences between these parts?

A: The IRLML6302TRPBF provides 780mA continuous drain current versus 750mA for the MGSF1P02LT1, representing a 4% increase in current capacity. The IRLML6302TRPBF has a lower gate threshold voltage (1.5V vs. 2.4V), enabling faster switching response at lower gate drive voltages. The MGSF1P02LT1 supports higher maximum gate voltage (±20V vs. ±12V). Both devices maintain identical 20V drain-to-source voltage rating and -55°C to 150°C operating temperature range.

Q: Are there thermal performance differences?

A: The IRLML6302TRPBF is rated for 540mW maximum power dissipation compared to 400mW for the MGSF1P02LT1, providing 35% additional thermal headroom. This difference reflects different measurement conditions and package thermal characteristics but does not affect substitution compatibility in typical applications.

Q: What is the significance of the product status designations?

A: The MGSF1P02LT1 is marked Obsolete, indicating end-of-life status and potential supply unavailability. The IRLML6302TRPBF is marked Not For New Designs, indicating the manufacturer is not recommending it for new product development but continues to support existing applications. For legacy system maintenance and production continuity, the IRLML6302TRPBF remains a valid substitute.

Q: How do RoHS compliance statuses affect part selection?

A: The MGSF1P02LT1 is RoHS non-compliant, while the IRLML6302TRPBF is ROHS3 Compliant. Applications subject to RoHS regulations (EU Directive 2011/65/EU and amendments) must use the IRLML6302TRPBF. Applications without RoHS requirements may use either part based on availability and supply chain considerations.

Q: Are the gate charge characteristics equivalent?

A: The IRLML6302TRPBF specifies gate charge (Qg) at 3.6 nC @ 4.45V. The MGSF1P02LT1 does not provide gate charge specification in the available data. The lower gate threshold voltage of the IRLML6302TRPBF (1.5V vs. 2.4V) indicates faster switching characteristics at standard gate drive voltages.

Q: Can both parts be used interchangeably in high-frequency switching applications?

A: Both devices are rated for the same operating temperature range and share compatible package thermal characteristics. The IRLML6302TRPBF exhibits lower input capacitance (97 pF @ 15V vs. 130 pF @ 5V), which may provide improved high-frequency performance. Application-specific circuit analysis is required to confirm suitability for particular switching frequency requirements.

Q: What packaging options are available for the substitute part?

A: The IRLML6302TRPBF is supplied in Cut Tape (CT) and Digi-Reel® packaging formats. The MGSF1P02LT1 packaging format is not specified in the available data. Both parts use the SOT-23-3 package designation for component-level compatibility.
