Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2SC1567AR is determined by electrical and mechanical compatibility within the following parameter constraints:

Electrical Compatibility Criteria:

• Transistor configuration must be NPN type
• Maximum collector-emitter breakdown voltage must equal or exceed 120 V
• Maximum collector current must equal or exceed 500 mA
• Maximum power dissipation must equal or exceed 1.2 W
• Operating temperature range must accommodate 150°C (TJ)
• Through Hole mounting type required

Mechanical Compatibility Criteria:

• Package must be compatible with TO-126-3 or TO-225AA footprints

The MJE270G meets these substitution criteria. Although the MJE270G is a Darlington configuration (NPN - Darlington) rather than a standard NPN transistor, it satisfies all electrical and mechanical requirements for direct substitution in the 2SC1567AR application space.

Parameter Comparison

Engineering Selection Recommendations

The MJE270G is an active product manufactured by onsemi and serves as a direct substitute for the obsolete 2SC1567AR. Selection of the MJE270G is supported by the following factors:

Product Status: The MJE270G is classified as Active, ensuring ongoing availability and manufacturing support, whereas the 2SC1567AR is Obsolete.

Electrical Performance: The MJE270G exceeds the electrical requirements of the 2SC1567AR across all critical parameters. Maximum collector current capability is 2 A compared to 500 mA, maximum power dissipation is 1.5 W compared to 1.2 W, and operating temperature range extends to −65°C to 150°C, encompassing the 2SC1567AR specification of 150°C.

Compliance & Certifications: The MJE270G is RoHS3 Compliant and REACH Unaffected, providing regulatory compliance for modern applications. Both devices share the same ECCN classification (EAR99).

Package Compatibility: Both devices utilize identical Through Hole package footprints (TO-225AA, TO-126-3), enabling direct mechanical substitution without PCB redesign.

Design Consideration: The MJE270G is a Darlington configuration with higher DC current gain (1500 minimum) and higher saturation voltage (3 V maximum) compared to the standard NPN 2SC1567AR (130 minimum gain, 400 mV saturation voltage). Applications requiring low saturation voltage or high-frequency operation above 6 MHz may require circuit evaluation.

Frequently Asked Questions (FAQ)

Q: Can the MJE270G directly replace the 2SC1567AR in all applications?

A: The MJE270G meets all electrical and mechanical substitution criteria for the 2SC1567AR. Both devices share compatible Through Hole package footprints and exceed the original specifications for current, voltage, and power handling. However, the Darlington configuration of the MJE270G introduces higher saturation voltage (3 V versus 400 mV) and lower transition frequency (6 MHz versus 120 MHz), which may affect performance in high-frequency or low-saturation-voltage applications.

Q: What is the primary reason for substituting the 2SC1567AR?

A: The 2SC1567AR is classified as Obsolete. The MJE270G is an Active product with ongoing manufacturing support, ensuring long-term availability for production and maintenance applications.

Q: Are the package footprints identical between these devices?

A: Yes. Both the 2SC1567AR and MJE270G utilize Through Hole mounting in TO-225AA and TO-126-3 package configurations, enabling direct mechanical substitution without PCB layout modifications.

Q: What are the key electrical differences between these transistors?

A: The MJE270G provides higher maximum collector current (2 A versus 500 mA), higher maximum power dissipation (1.5 W versus 1.2 W), and significantly higher DC current gain (1500 minimum versus 130 minimum). The MJE270G exhibits higher saturation voltage (3 V versus 400 mV) and lower transition frequency (6 MHz versus 120 MHz) due to its Darlington configuration.

Q: Does the MJE270G meet modern regulatory requirements?

A: Yes. The MJE270G is RoHS3 Compliant and REACH Unaffected, meeting current regulatory standards for electronic components. The 2SC1567AR product status does not specify modern compliance certifications.

Q: What applications may require circuit evaluation before substitution?

A: Applications requiring transition frequencies above 6 MHz or saturation voltages below 3 V should undergo circuit evaluation, as the MJE270G's Darlington configuration differs from the standard NPN topology of the 2SC1567AR.
