2N6520-AP Equivalent & Substitute Parts

Part Overview

The 2N6520-AP is a PNP bipolar junction transistor (BJT) rated for 350 V collector-emitter breakdown voltage and 500 mA maximum collector current. Manufactured by Micro Commercial Co, this device is packaged in a TO-92 through-hole configuration and is rated for 625 mW power dissipation with a transition frequency of 40 MHz. The 2N6520-AP is classified as obsolete, making identification of equivalent and substitute parts necessary for ongoing design support and production continuity. Substitute parts must maintain electrical and mechanical compatibility while meeting current availability and compliance requirements.

Parameter Comparison

Engineering Selection Recommendations

The 2N6520TA manufactured by onsemi is a direct electrical and mechanical substitute for the obsolete 2N6520-AP. Selection of the 2N6520TA is supported by the following factors:

Compliance and Availability: The 2N6520TA holds active product status with ROHS3 compliance certification, ensuring long-term availability and regulatory alignment. The main part 2N6520-AP is classified as obsolete, creating supply chain risk for new production and maintenance applications.

Electrical Equivalence: All critical electrical parameters match the 2N6520-AP specification: 350 V breakdown voltage, 500 mA maximum collector current, 625 mW power rating, and identical saturation voltage characteristics. The transition frequency of 200 MHz in the 2N6520TA exceeds the 40 MHz specification of the main part, providing enhanced performance margin without introducing incompatibility.

Mechanical Compatibility: Both devices utilize identical TO-92-3 through-hole packaging with formed leads, ensuring direct pin-for-pin compatibility in existing PCB layouts and socket configurations.

Packaging Format: The 2N6520TA is supplied in Cut Tape (CT) packaging, suitable for automated assembly processes and component handling workflows.

Frequently Asked Questions (FAQ)

Q: Can the 2N6520TA be used as a direct replacement for the 2N6520-AP in existing designs?

A: Yes. The 2N6520TA meets all critical electrical parameters (350 V breakdown, 500 mA collector current, 625 mW power, identical saturation voltage) and uses identical TO-92-3 through-hole packaging. Pin-for-pin substitution is supported.

Q: What is the significance of the higher transition frequency (200 MHz) in the 2N6520TA compared to the 2N6520-AP (40 MHz)?

A: The 200 MHz transition frequency in the 2N6520TA exceeds the 40 MHz specification of the 2N6520-AP. This represents enhanced frequency performance and does not create incompatibility. Applications operating within the 40 MHz specification of the original part will function within the performance envelope of the substitute.

Q: Are there differences in DC current gain between these parts?

A: The 2N6520-AP specifies a minimum DC current gain (hFE) of 30 at 30 mA collector current and 10 V collector-emitter voltage. The 2N6520TA specifies a minimum DC current gain of 20 at 50 mA collector current and 10 V collector-emitter voltage. These variations are within allowable parameter ranges for PNP BJT substitution and do not affect functional compatibility in standard switching and amplification applications.

Q: What is the difference between the packaging formats (TO-92 versus TO-92-3)?

A: Both designations refer to the same three-lead through-hole package configuration. TO-92-3 is the formal designation used by onsemi; TO-92 is the generic industry designation. The physical package dimensions, lead spacing, and pin configuration are identical.

Q: Why is the 2N6520-AP classified as obsolete?

A: The 2N6520-AP is no longer in active production by Micro Commercial Co. The 2N6520TA from onsemi provides equivalent electrical and mechanical functionality with active product status and current compliance certifications.

Q: Are both parts RoHS compliant?

A: Yes. Both the 2N6520-AP and 2N6520TA are ROHS3 compliant, meeting restrictions on hazardous substances in electrical and electronic equipment.

Q: What is the moisture sensitivity level (MSL) of the 2N6520TA?

A: The 2N6520TA is classified as Not Applicable for moisture sensitivity level, indicating no moisture-related handling restrictions for this component.
