MPF960 N-Channel MOSFET 60V 2A Equivalent & Substitute Parts

Part Overview

The MPF960 is an N-Channel MOSFET rated for 60V drain-to-source voltage with 2A continuous drain current in a Through Hole TO-92-3 package. This device is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity. The MPF960 operates across a temperature range of -55°C to 150°C and dissipates up to 1W, suitable for general-purpose switching applications in legacy and new designs requiring compatible pin configurations and electrical performance.

Substitute Part Grouping Explanation

Substitution of the MPF960 is determined by strict adherence to the following electrical and mechanical parameters:

Critical Matching Parameters:

Drain-to-Source Voltage (Vdss): Must equal or exceed 60V
FET Type: Must be N-Channel MOSFET
Mounting Type: Must be Through Hole
Package Compatibility: Must be TO-92-3 or TO-92-compatible form factor
Operating Temperature Range: Must span -55°C to 150°C
Gate Threshold Voltage: Must be compatible with 10V drive voltage applications

Performance Considerations:

Continuous Drain Current (Id): Substitute parts rated at 500mA or higher are acceptable for applications not requiring the full 2A capability
Rds On: Lower values indicate improved performance; values at or below 2Ohm @ 10V are acceptable
Power Dissipation: Minimum 700mW acceptable for most applications; 1W preferred for thermal margin

All four substitute parts meet the critical matching parameters. Differences in drain current ratings and power dissipation reflect available active alternatives to the obsolete MPF960.

Engineering Selection Recommendations

Primary Recommendation: ZVN4206A or ZVN4206ASTZ

The ZVN4206A and ZVN4206ASTZ are functionally equivalent to the MPF960 with the following advantages:

Active product status ensures long-term availability and supply chain stability
ROHS3 compliance meets current environmental and regulatory requirements
Superior Rds On performance (1Ohm @ 1.5A, 10V) compared to MPF960 (1.7Ohm @ 1A, 10V)
Identical 60V Vdss rating and ±20V Vgs maximum
Full -55°C to 150°C operating temperature range
TO-92-3 package (ZVN4206A) or E-Line-3 package (ZVN4206ASTZ) both compatible with legacy TO-92 footprints

The ZVN4206A is supplied in bulk packaging, while ZVN4206ASTZ is supplied in Tape & Reel format for automated assembly.

Secondary Recommendation: TN0606N3-G

The TN0606N3-G is suitable for applications where drain current requirements do not exceed 500mA:

Active product status with ROHS3 compliance
Excellent Rds On performance (1.5Ohm @ 750mA, 10V)
Lower gate threshold voltage (2V @ 1mA) provides improved switching characteristics
TO-92-3 package maintains direct footprint compatibility
1W power dissipation rating matches MPF960

Alternative Consideration: ZVN2106ASTZ

The ZVN2106ASTZ is applicable for applications with drain current requirements up to 450mA:

Active product status with ROHS3 compliance
E-Line-3 package compatible with TO-92 footprints
700mW power dissipation suitable for moderate thermal environments
Supplied in Cut Tape format for component handling

Compliance Note:

All substitute parts are ROHS3 compliant and REACH unaffected, addressing regulatory requirements that the obsolete MPF960 does not meet. Selection should prioritize active products to ensure supply continuity and compliance with current manufacturing standards.

Frequently Asked Questions (FAQ)

Q: Can the ZVN4206A directly replace the MPF960 in existing designs?

A: Yes. The ZVN4206A matches all critical electrical parameters: 60V Vdss, N-Channel MOSFET technology, ±20V Vgs maximum, and -55°C to 150°C operating range. The TO-92-3 package provides identical pin configuration and footprint compatibility. The lower Rds On (1Ohm vs. 1.7Ohm) represents improved performance.

Q: What is the difference between ZVN4206A and ZVN4206ASTZ?

A: Both parts are electrically identical with identical electrical specifications. The difference is packaging format: ZVN4206A is supplied in bulk, while ZVN4206ASTZ is supplied in Tape & Reel format. ZVN4206ASTZ uses an E-Line-3 package instead of TO-92-3, though both are TO-92 compatible. Selection depends on assembly process requirements.

Q: Why is the TN0606N3-G rated for only 500mA when the MPF960 is rated for 2A?

A: The TN0606N3-G is a lower-current variant designed for applications not requiring 2A capability. It remains a valid substitute for designs operating below 500mA continuous drain current. For applications requiring the full 2A rating, ZVN4206A or ZVN4206ASTZ are appropriate selections.

Q: Are all substitute parts RoHS compliant?

A: Yes. All four substitute parts are ROHS3 compliant. The original MPF960 is RoHS non-compliant, making substitution necessary for designs subject to RoHS requirements.

Q: What is the significance of the E-Line package used in ZVN2106ASTZ and ZVN4206ASTZ?

A: The E-Line package is a Through Hole form factor compatible with standard TO-92 footprints. It provides the same pin spacing and mounting characteristics as TO-92-3, ensuring direct PCB compatibility. E-Line packaging is commonly used for automated tape-and-reel assembly processes.

Q: Can I use the ZVN2106ASTZ in a design originally specified for the MPF960?

A: The ZVN2106ASTZ is suitable only if the application's continuous drain current requirement does not exceed 450mA. The 60V Vdss rating, N-Channel type, and operating temperature range match the MPF960. However, the reduced current rating and 700mW power dissipation (vs. 1W) must be verified against circuit requirements.

Q: What inventory levels are available for each substitute?

A: Current inventory levels are: TN0606N3-G (2,412 pcs), ZVN2106ASTZ (3,960 pcs), ZVN4206A (900,100 pcs), and ZVN4206ASTZ (12,400 pcs). ZVN4206A offers the highest availability.

Q: Are there any thermal considerations when substituting these parts?

A: The MPF960 and TN0606N3-G both dissipate 1W maximum, while ZVN2106ASTZ and ZVN4206A/ASTZ dissipate 700mW maximum. For applications operating near thermal limits, verify that the 700mW rating is sufficient. Lower Rds On values in substitute parts may reduce power dissipation in switching applications.
