Substitute Part Grouping Explanation

Substitute parts for the MJD3055RLG are identified based on electrical and mechanical parameter equivalence. All substitute candidates maintain identical specifications across the following critical parameters:

Transistor Type: NPN
Maximum Collector Current: 10 A
Collector-Emitter Breakdown Voltage: 60 V
Saturation Voltage: 0.8 V @ 3.3 A, 10 A
Collector Cutoff Current: 50 µA
DC Current Gain (hFE): 20 minimum @ 4 A, 4 V
Maximum Power Dissipation: 1.75 W
Transition Frequency: 2 MHz
Operating Temperature Range: -55°C to 150°C
Package: TO-252-3 DPAK

Engineering Selection Recommendations

All three parts—MJD3055RLG, MJD3055T4G, and NJVMJD3055T4G—are manufactured by onsemi and maintain active product status. Each part carries identical electrical specifications, thermal operating range, and regulatory compliance certifications (RoHS3, REACH Unaffected, EAR99 classification).

Selection between these parts is determined by packaging format requirements and supply chain availability:

MJD3055RLG is supplied in Tape & Reel (TR) format with 15,200 units in stock.

MJD3055T4G is supplied in Cut Tape (CT) & Digi-Reel® format with 20,400 units in stock, suitable for applications requiring individual component handling or smaller batch quantities.

NJVMJD3055T4G is supplied in Tape & Reel (TR) format with 20,100 units in stock, offering an alternative TR packaging option with a different base product number designation.

All three parts are suitable for direct substitution in circuit designs where the MJD3055RLG is specified, provided that the receiving assembly process accommodates the respective packaging format.

Frequently Asked Questions (FAQ)

Q: Can MJD3055T4G replace MJD3055RLG in production assembly?

A: Yes. MJD3055T4G is electrically and mechanically equivalent to MJD3055RLG. The difference is packaging format: MJD3055RLG is supplied in Tape & Reel, while MJD3055T4G is supplied in Cut Tape & Digi-Reel. Assembly equipment compatibility with the packaging format must be confirmed.

Q: What is the difference between MJD3055RLG and NJVMJD3055T4G?

A: Both parts are NPN transistors with identical electrical specifications and DPAK packaging. The primary difference is the base product number designation (MJD3055 versus NJVMJD3055) and packaging format (MJD3055RLG in Tape & Reel versus NJVMJD3055T4G in Tape & Reel). Electrical performance and thermal characteristics are equivalent.

Q: Are all three parts RoHS3 compliant?

A: Yes. MJD3055RLG, MJD3055T4G, and NJVMJD3055T4G are all RoHS3 compliant with MSL rating of 1 (Unlimited moisture sensitivity).

Q: Can these parts be used interchangeably in high-temperature applications?

A: Yes. All three parts operate across the identical temperature range of -55°C to 150°C (junction temperature). No thermal performance differences exist between the parts.

Q: What is the significance of the packaging format difference?

A: Packaging format affects component handling and assembly process compatibility. Tape & Reel (TR) format is standard for high-volume automated assembly. Cut Tape (CT) & Digi-Reel format accommodates lower-volume production or manual assembly processes. Electrical and mechanical specifications remain unchanged.

Q: Are there any compliance or regulatory differences between these parts?

A: No. All three parts carry identical regulatory certifications: RoHS3 Compliant, REACH Unaffected, and EAR99 ECCN classification. HTSUS code 8541.29.0095 applies to all variants.
