MCH3376-TL-E Equivalent & Substitute Parts

Part Overview

The MCH3376-TL-E is a P-Channel MOSFET manufactured by onsemi, rated for 20V drain-to-source voltage with 1.5A continuous drain current at 25°C. The device is housed in a 3-MCPH (SC-70, SOT-323) surface mount package and dissipates a maximum of 800mW at ambient temperature. This part is classified as obsolete, making identification of equivalent and substitute components necessary for ongoing design support and production continuity. Substitute parts must maintain electrical compatibility across critical parameters including voltage rating, current capacity, and thermal characteristics while accommodating the surface mount package format.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MCH3376-TL-E is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• FET Type: P-Channel (required for circuit polarity)
• Drain to Source Voltage (Vdss): 20V minimum (voltage rating must equal or exceed the original specification)
• Package / Case: SC-70 or SOT-323 (physical and electrical footprint compatibility)
• Mounting Type: Surface Mount (assembly process compatibility)

Performance Criteria:

• Current - Continuous Drain (Id) @ 25°C: Must support the application's current requirements without exceeding thermal limits
• Rds On (Max): Lower on-resistance values indicate improved performance and reduced power dissipation
• Power Dissipation (Max): Must accommodate thermal design constraints

The identified substitute parts NTS4101PT1G and PMF170XP,115 satisfy all mandatory compatibility criteria. Both are P-Channel MOSFETs rated for 20V Vdss, packaged in SC-70/SOT-323 surface mount configurations, and manufactured by established semiconductor suppliers with active product status.

Parameter Comparison

Engineering Selection Recommendations

NTS4101PT1G (onsemi): This substitute is manufactured by onsemi, the original manufacturer of the MCH3376-TL-E, ensuring design continuity and process consistency. The NTS4101PT1G maintains the 20V Vdss rating and SC-70/SOT-323 package format. With a continuous drain current of 1.37A at 25°C, it supports applications requiring up to 1.37A. The device exhibits superior on-resistance performance (120mOhm @ 1A, 4.5V) compared to the original part, resulting in lower power dissipation (329mW maximum). The active product status ensures long-term availability and supply chain stability. RoHS3 compliance and MSL-1 rating align with the original specification.

PMF170XP,115 (Nexperia USA Inc.): This substitute is manufactured by Nexperia USA Inc., a recognized semiconductor supplier with established quality standards. The PMF170XP,115 maintains the 20V Vdss rating and SC-70/SOT-323 package format. With a continuous drain current of 1.0A at 25°C, it is suitable for applications requiring up to 1.0A. The device provides competitive on-resistance performance (200mOhm @ 1A, 4.5V) and reduced power dissipation (290mW maximum). The active product status ensures availability. RoHS3 compliance and MSL-1 rating align with the original specification.

Selection Guidance: For applications requiring current capacity at or below 1.37A, the NTS4101PT1G is the preferred substitute due to manufacturer continuity with onsemi and superior electrical performance characteristics. For applications requiring current capacity at or below 1.0A, the PMF170XP,115 provides an alternative from an established supplier. Both substitutes are suitable for designs where the MCH3376-TL-E is no longer available due to obsolescence.

Frequently Asked Questions (FAQ)

Q: Can the NTS4101PT1G directly replace the MCH3376-TL-E in existing designs?

A: The NTS4101PT1G is electrically and mechanically compatible with the MCH3376-TL-E for applications requiring continuous drain current up to 1.37A. Both devices share identical voltage ratings (20V Vdss), package format (SC-70/SOT-323), and mounting type (surface mount). The NTS4101PT1G exhibits improved on-resistance characteristics, which reduces power dissipation in the circuit. No circuit modifications are required for substitution.

Q: Can the PMF170XP,115 directly replace the MCH3376-TL-E in existing designs?

A: The PMF170XP,115 is electrically and mechanically compatible with the MCH3376-TL-E for applications requiring continuous drain current up to 1.0A. Both devices share identical voltage ratings (20V Vdss), package format (SC-70/SOT-323), and mounting type (surface mount). The PMF170XP,115 exhibits improved on-resistance characteristics compared to the original part. No circuit modifications are required for substitution, provided the application current does not exceed 1.0A.

Q: What is the primary difference between the two substitute parts?

A: The primary difference is continuous drain current capacity. The NTS4101PT1G supports 1.37A at 25°C, while the PMF170XP,115 supports 1.0A at 25°C. Both maintain the 20V voltage rating and SC-70/SOT-323 package format. The NTS4101PT1G is manufactured by onsemi, the original manufacturer of the MCH3376-TL-E, providing design continuity. The PMF170XP,115 is manufactured by Nexperia USA Inc.

Q: Are both substitute parts RoHS3 compliant?

A: Yes, both the NTS4101PT1G and PMF170XP,115 are RoHS3 compliant and carry MSL-1 (Unlimited) moisture sensitivity ratings, matching the compliance profile of the original MCH3376-TL-E.

Q: What is the operating temperature range for the substitute parts?

A: Both substitute parts operate across a temperature range of −55°C to 150°C (TJ), which encompasses the 150°C maximum junction temperature of the original MCH3376-TL-E. This extended lower temperature limit provides additional operational flexibility.

Q: How do the on-resistance values compare across the three parts?

A: The MCH3376-TL-E specifies 241mOhm maximum on-resistance at 750mA and 4.5V gate-source voltage. The NTS4101PT1G specifies 120mOhm maximum at 1A and 4.5V, representing a 50% reduction. The PMF170XP,115 specifies 200mOhm maximum at 1A and 4.5V, representing an 17% reduction. Lower on-resistance values result in reduced power dissipation during operation.

Q: Are the package dimensions identical across all three parts?

A: All three parts use the SC-70/SOT-323 surface mount package format, ensuring identical footprints and assembly compatibility. No PCB layout modifications are required when substituting between these parts.
