Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2N5366_D27Z is determined by electrical and mechanical compatibility within the following criteria:

Electrical Parameters (Required for Substitution):

• Transistor polarity must remain PNP
• Maximum collector current (Ic) must equal or exceed 500 mA
• Maximum collector-emitter breakdown voltage (VCEO) must equal or exceed 40 V
• Maximum power dissipation must equal or exceed 625 mW
• DC current gain (hFE) minimum must equal or exceed 100

Mechanical Parameters (Required for Substitution):

• Package type must be TO-92-3 through-hole configuration
• Pin configuration and lead spacing must be compatible with TO-226-3 standard

The KSP2907ACTA meets all substitution criteria with enhanced electrical ratings and active product status.

Engineering Selection Recommendations

The KSP2907ACTA is a direct substitute for the 2N5366_D27Z based on the following engineering criteria:

Electrical Compatibility: The KSP2907ACTA exceeds the minimum electrical requirements of the 2N5366_D27Z across all critical parameters. Maximum collector current is increased from 500 mA to 600 mA, and maximum collector-emitter breakdown voltage is increased from 40 V to 60 V. These enhancements provide additional design margin without compromising circuit functionality.

Mechanical Compatibility: Both devices utilize identical TO-92-3 through-hole packaging with TO-226-3 standard lead configuration, ensuring direct pin-for-pin compatibility in existing PCB layouts.

Product Status and Compliance: The KSP2907ACTA maintains active production status with ROHS3 compliance and REACH unaffected designation. The 2N5366_D27Z is obsolete, making the KSP2907ACTA the appropriate long-term supply solution.

Thermal Performance: Both devices support identical maximum junction temperature of 150°C, maintaining thermal design consistency.

Frequently Asked Questions (FAQ)

Q: Can the KSP2907ACTA directly replace the 2N5366_D27Z in existing designs?

A: Yes. The KSP2907ACTA is a direct pin-for-pin replacement with identical TO-92-3 package configuration and superior electrical ratings. No circuit modifications are required.

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

A: The KSP2907ACTA provides higher maximum collector current (600 mA vs. 500 mA) and higher collector-emitter breakdown voltage (60 V vs. 40 V). The KSP2907ACTA is in active production, while the 2N5366_D27Z is obsolete.

Q: Are there any electrical parameter mismatches that would prevent substitution?

A: No. All critical electrical parameters of the KSP2907ACTA meet or exceed the 2N5366_D27Z specifications. The higher ratings of the KSP2907ACTA ensure compatibility with existing circuit designs.

Q: Does the KSP2907ACTA require different PCB footprint or lead spacing?

A: No. Both transistors use the TO-92-3 package with identical lead spacing and pin configuration. Existing PCB layouts require no modification.

Q: What is the compliance status of the KSP2907ACTA?

A: The KSP2907ACTA is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Why is the 2N5366_D27Z classified as obsolete?

A: Obsolete status indicates that onsemi has discontinued production of this device. The KSP2907ACTA represents the active alternative for new designs and ongoing production requirements.
