Substitute Part Grouping Explanation

Substitution of the FJP13007 is determined by strict equivalence in the following electrical and mechanical parameters:

Primary Substitution Criteria:

Transistor Type: NPN
Voltage - Collector Emitter Breakdown (Max): 400 V
Current - Collector (Ic) (Max): 8 A
Power - Max: 80 W
Package / Case: TO-220-3
Mounting Type: Through Hole

Secondary Compatibility Factors:

Vce Saturation characteristics
DC Current Gain (hFE) specifications
Operating Temperature range
Product Status (Active status preferred for new designs)

Parts are classified as Direct Substitutes when all primary criteria are met with identical electrical ratings. Parts are classified as Similar Substitutes when they meet primary electrical criteria but have reduced current ratings (4 A to 5 A) or other parameter variations that require application-level verification.

Frequently Asked Questions (FAQ)

Q: Can MJE13007G be used as a direct replacement for FJP13007?

A: Yes. MJE13007G meets all primary substitution criteria: 8 A collector current, 400 V breakdown voltage, 80 W power rating, and TO-220-3 package. MJE13007G is an active product with improved transition frequency (14 MHz) and ROHS3 compliance, making it suitable for both legacy system support and new designs.

Q: What is the difference between ST13007 and ST13007D?

A: Both parts are manufactured by STMicroelectronics with identical electrical ratings (8 A, 400 V, 80 W). ST13007D is the tube-packaged variant, while ST13007 is also available in tube packaging. Both are active products with ROHS3 compliance. Selection between them depends on packaging and supplier availability requirements.

Q: Can BUL138 replace FJP13007 in all applications?

A: BUL138 has a reduced maximum collector current rating of 5 A compared to FJP13007's 8 A. BUL138 is suitable only for applications where the circuit design operates at or below 5 A collector current. Applications requiring the full 8 A capability require a direct substitute with identical current rating.

Q: Are all substitute parts RoHS compliant?

A: Most substitute parts listed are ROHS3 compliant. FJP13007 itself is not explicitly marked as RoHS compliant in the provided specifications. MJE13007G, ST13007D, ST13007, PHE13007,127, BUJ105A,127, FJP3305H1TU, and BUL138 all carry RoHS3 or RoHS compliance certifications.

Q: What is the significance of the TO-220-3 package specification?

A: TO-220-3 is the through-hole package format with three leads (collector, base, emitter). All listed substitute parts maintain this package specification, ensuring mechanical and thermal compatibility with existing PCB layouts and heat sink mounting arrangements. Package compatibility is a mandatory substitution criterion.

Q: Why is FJP13007 classified as obsolete?

A: FJP13007 is marked as obsolete by onsemi, indicating it is no longer in active production. Direct substitutes with active product status (MJE13007G, ST13007, ST13007D, PHE13007,127, BUJ105A,127) are available from multiple manufacturers and are recommended for new designs and long-term procurement planning.

Q: Can parts with different Vce saturation values be interchanged?

A: Vce saturation differences affect switching losses and thermal performance. Parts with lower Vce saturation (such as PHE13007,127 at 0.35V or BUJ105A,127 at 1V) generate less heat during saturation. Parts with higher Vce saturation (such as ST13007D at 2V) may require thermal design adjustments. Application-specific circuit analysis determines whether Vce saturation variation is acceptable.

Q: What does the transition frequency specification indicate?

A: Transition frequency (fT) indicates the maximum frequency at which the transistor maintains useful gain. FJP13007 specifies 4 MHz, while MJE13007G specifies 14 MHz. Higher transition frequency allows operation in faster switching applications. For low-frequency switching applications, transition frequency differences are not limiting factors.
