MJF32C Equivalent & Substitute Parts

Part Overview

The MJF32C is a PNP bipolar junction transistor manufactured by onsemi, rated for 100 V collector-emitter breakdown voltage and 3 A maximum collector current. This device is packaged in a TO-220-3 Full Pack through-hole configuration and is designed for general-purpose switching and amplification applications requiring 2 W power dissipation capability.

The MJF32C is classified as obsolete. Locating equivalent substitute parts is necessary to maintain design continuity and ensure component availability for new production builds, repairs, and system upgrades where this transistor specification remains functionally appropriate.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MJF32C is determined by strict equivalence across the following electrical and mechanical parameters:

• Transistor Type: PNP polarity must be maintained
• Maximum Collector Current (Ic): 3 A minimum rating required
• Collector-Emitter Breakdown Voltage: 100 V minimum rating required
• Vce Saturation Characteristics: 1.2 V @ 375mA, 3A specification must be met
• Collector Cutoff Current: 300 µA maximum specification must be met
• DC Current Gain (hFE): 10 minimum @ 3A, 4V must be satisfied
• Maximum Power Dissipation: 2 W minimum rating required
• Transition Frequency: 3 MHz minimum specification must be met
• Operating Temperature Range: -65°C to 150°C (TJ) must be supported
• Package Configuration: TO-220-3 Full Pack through-hole mounting required

Only parts meeting all of these criteria are classified as direct electrical and mechanical equivalents.

Parameter Comparison

Engineering Selection Recommendations

The MJF32CG is a direct electrical and mechanical equivalent to the MJF32C. All specified electrical parameters, including collector current, breakdown voltage, saturation characteristics, current gain, power rating, and frequency response, are identical. Both devices utilize the same TO-220-3 Full Pack through-hole package configuration and support the same operating temperature range.

The primary distinction between these parts is product status and regulatory compliance. The MJF32C is classified as obsolete, while the MJF32CG is active and in current production. The MJF32CG carries ROHS3 compliance certification, whereas the MJF32C is RoHS non-compliant. Both parts maintain REACH Unaffected status and share the same ECCN and HTSUS classifications.

For new designs and production applications, the MJF32CG is the appropriate selection due to its active product status and modern compliance certifications. For legacy system maintenance where the original MJF32C specification is required, the MJF32CG provides full functional and mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the MJF32CG be used as a direct replacement for the MJF32C in existing designs?

A: Yes. The MJF32CG is electrically and mechanically identical to the MJF32C across all specified parameters. Pin configuration, package dimensions, and electrical characteristics are equivalent. Direct substitution is supported without circuit modification.

Q: What is the difference between the MJF32C and MJF32CG?

A: The electrical and mechanical specifications are identical. The MJF32C is obsolete, while the MJF32CG is an active product. The MJF32CG carries ROHS3 compliance certification, whereas the MJF32C is RoHS non-compliant. Both parts are manufactured by onsemi and share the same base product number (MJF32).

Q: Are there packaging differences between MJF32C and MJF32CG?

A: Both parts are supplied in TO-220-3 Full Pack through-hole packages. The MJF32C packaging type is listed as unspecified in the original documentation, while the MJF32CG is supplied in Tube packaging. The physical package configuration (TO-220FP) and pin layout are identical.

Q: What are the key electrical parameters that define substitution compatibility?

A: Substitution compatibility is determined by matching the following parameters: PNP transistor type, 3 A maximum collector current, 100 V collector-emitter breakdown voltage, 1.2 V saturation voltage at specified conditions, 300 µA collector cutoff current, 10 minimum DC current gain at 3A and 4V, 2 W maximum power dissipation, 3 MHz transition frequency, and -65°C to 150°C operating temperature range.

Q: Is the MJF32CG suitable for new production designs?

A: Yes. The MJF32CG is an active product with current manufacturing support. It carries ROHS3 compliance certification, making it appropriate for new designs subject to modern regulatory requirements. The electrical specifications remain unchanged from the obsolete MJF32C.

Q: What is the inventory status of these parts?

A: The MJF32C has 61,200 pieces in stock as new original inventory. The MJF32CG has 3,400 pieces in stock as new original inventory. Availability should be confirmed with the supplier for specific procurement timelines.
