NJVMJD47T4G Equivalent & Substitute Parts

Part Overview

The NJVMJD47T4G is an NPN bipolar junction transistor manufactured by onsemi, rated for 250V collector-emitter breakdown voltage and 1A maximum collector current. This surface mount device is housed in a DPAK (TO-252-3) package and is designed for general-purpose switching and amplification applications requiring moderate power dissipation up to 1.56W. The part maintains Active product status and is RoHS3 compliant. Substitute parts are identified when equivalent electrical specifications and mechanical packaging allow direct replacement in circuit designs without functional degradation.

Substitute Part Grouping Explanation

Substitute parts for the NJVMJD47T4G are identified based on strict equivalence across the following critical parameters:

Transistor Type: NPN configuration
Voltage Rating: 250V collector-emitter breakdown voltage (maximum)
Current Rating: 1A maximum collector current
Power Dissipation: 1.56W maximum
Frequency Response: 10MHz transition frequency
DC Current Gain: 30 (minimum) at specified bias conditions
Saturation Characteristics: 1V maximum Vce at rated conditions
Package: TO-252-3 DPAK surface mount form factor
Compliance: RoHS3 compliant, REACH unaffected status

Parts meeting all these parameters are classified as parametric equivalents and direct substitutes. No deviations from specified electrical or mechanical characteristics are permitted for substitution classification.

Frequently Asked Questions (FAQ)

Q: Can the MJD47T4G replace the NJVMJD47T4G in existing designs?

A: Yes. The MJD47T4G is a parametric equivalent with identical electrical specifications, thermal characteristics, and DPAK surface mount packaging. Direct substitution is supported without circuit modification.

Q: Are there differences in the base product numbers?

A: The NJVMJD47T4G has base product number NJVMJD47, while the MJD47T4G has base product number MJD47. These designations reflect different product lines within onsemi's portfolio, but the "T4G" suffix indicates identical electrical and mechanical specifications for both parts.

Q: What is the significance of the DPAK package designation?

A: DPAK (TO-252-3) is a surface mount package with two leads plus a thermal tab. Both substitute parts use this identical package, ensuring PCB footprint compatibility and thermal management characteristics remain unchanged during substitution.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the NJVMJD47T4G and MJD47T4G are RoHS3 compliant, REACH unaffected, and carry MSL Level 1 (Unlimited) moisture sensitivity ratings. Regulatory and environmental compliance is equivalent.

Q: What are the critical electrical parameters that define substitution eligibility?

A: Substitution eligibility is determined by matching: NPN transistor type, 250V collector-emitter breakdown voltage, 1A maximum collector current, 1.56W power dissipation, 10MHz transition frequency, 30 minimum DC current gain at specified bias, and 1V maximum Vce saturation at rated conditions.

Q: Is there a performance difference between these parts?

A: No. Both parts are manufactured to identical specifications and exhibit equivalent performance characteristics across all rated operating conditions and temperature ranges (-65°C to 150°C junction temperature).
