2N6517RLRPG Equivalent & Substitute Parts

Part Overview

The 2N6517RLRPG is an NPN bipolar junction transistor manufactured by onsemi, rated for 350 V collector-emitter breakdown voltage and 500 mA maximum collector current. This device is packaged in a TO-92 through-hole configuration and is designed for general-purpose switching and amplification applications. The 2N6517RLRPG carries an obsolete product status, making identification of equivalent and substitute parts essential for design continuity and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2N6517RLRPG is determined by electrical and mechanical parameter compatibility within the NPN bipolar transistor category. The critical parameters governing substitution are:

Electrical Parameters:

• Voltage - Collector Emitter Breakdown (Max): Must equal or exceed 350 V
• Current - Collector (Ic) (Max): Must equal or exceed 500 mA
• Power - Max: Must equal or exceed 625 mW
• Frequency - Transition: Must support application frequency requirements
• DC Current Gain (hFE): Must meet or exceed minimum specified gain

Mechanical Parameters:

• Mounting Type: Through Hole
• Package / Case: TO-92-3 compatible pinout

Substitute parts are classified into two categories:

Direct Equivalent (2N6517TA): Maintains identical electrical specifications and is manufactured by the same supplier (onsemi) with active product status.

Similar Substitute (KSP42TA): Shares the same mounting type and package configuration but operates at reduced voltage rating (300 V vs. 350 V) and frequency (50 MHz vs. 200 MHz). This part is suitable only for applications where the lower electrical ratings are acceptable.

Engineering Selection Recommendations

2N6517TA (Direct Equivalent - Recommended Primary Substitute)

The 2N6517TA is the direct functional equivalent of the 2N6517RLRPG. This part maintains identical electrical specifications across all critical parameters: 350 V breakdown voltage, 500 mA collector current, 625 mW power dissipation, and 200 MHz transition frequency. The 2N6517TA carries active product status from onsemi and is ROHS3 compliant, ensuring long-term availability and regulatory compliance. The primary distinction is packaging format (Cut Tape vs. unspecified for the main part), which does not affect electrical performance or pinout compatibility. This part is suitable for direct replacement in all applications where the 2N6517RLRPG was originally specified.

KSP42TA (Similar Substitute - Conditional Use)

The KSP42TA is a similar NPN transistor in the same TO-92-3 package but with reduced electrical ratings. The collector-emitter breakdown voltage is 300 V (versus 350 V), and the transition frequency is 50 MHz (versus 200 MHz). This part is suitable only for applications where the design specifications do not require the full 350 V rating or 200 MHz frequency capability. The KSP42TA offers higher DC current gain (40 vs. 20 at specified test conditions) and lower saturation voltage, which may provide performance advantages in specific low-frequency switching applications. This part carries active product status and ROHS3 compliance.

Both substitute parts are manufactured by onsemi and maintain REACH compliance with the main part.

Frequently Asked Questions (FAQ)

Q: Can the 2N6517TA be used as a direct replacement for the 2N6517RLRPG?

A: Yes. The 2N6517TA is electrically and mechanically identical to the 2N6517RLRPG. Both devices share the same NPN type, 350 V breakdown voltage, 500 mA collector current, 625 mW power rating, 200 MHz transition frequency, and TO-92-3 package configuration. The 2N6517TA is the recommended substitute due to its active product status.

Q: What are the limitations of using KSP42TA as a substitute?

A: The KSP42TA operates at reduced voltage and frequency ratings. The collector-emitter breakdown voltage is 300 V instead of 350 V, and the transition frequency is 50 MHz instead of 200 MHz. Applications requiring the full 350 V rating or operating at frequencies above 50 MHz cannot use this part. Verify that your circuit design operates within these reduced specifications before selecting KSP42TA.

Q: Are all substitute parts in the same package?

A: Yes. The 2N6517RLRPG, 2N6517TA, and KSP42TA are all packaged in TO-92-3 through-hole configuration with identical pinout. No PCB layout modifications are required for substitution.

Q: What is the difference between the 2N6517RLRPG and 2N6517TA packaging?

A: The 2N6517RLRPG is supplied in unspecified packaging, while the 2N6517TA is supplied in Cut Tape (CT) format. Both use the same TO-92-3 component package. Cut Tape packaging is standard for active production parts and does not affect electrical performance or board-level compatibility.

Q: Are the substitute parts RoHS and REACH compliant?

A: The 2N6517TA and KSP42TA are both ROHS3 compliant and REACH unaffected. The 2N6517RLRPG is REACH unaffected. Verify RoHS compliance requirements for your specific application and region.

Q: Why is the 2N6517RLRPG marked as obsolete?

A: The 2N6517RLRPG is an obsolete part number. The 2N6517TA is the active production equivalent from onsemi and should be used for new designs and ongoing procurement.
