Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2N6517RLRA is determined by electrical and mechanical compatibility across the following critical parameters:

Direct Electrical Compatibility Requirements:

• Transistor type (NPN)
• Voltage rating (Collector-Emitter Breakdown ≥ 350 V)
• Current rating (Collector current ≥ 500 mA)
• Power dissipation (≥ 625 mW)
• Frequency response (Transition frequency ≥ 200 MHz)
• DC current gain characteristics
• Saturation voltage performance
• Leakage current specifications

Mechanical Compatibility Requirements:

• Through Hole mounting type
• TO-92-3 package configuration
• Pin configuration and lead formation

Substitute parts are classified into two categories:

Direct Substitutes: Parts that maintain identical or superior electrical specifications across all critical parameters while offering improved product status or compliance certifications.

Similar Substitutes: Parts that maintain functional compatibility within the same package and mounting type but with modified electrical specifications that may require circuit evaluation for specific applications.

Engineering Selection Recommendations

2N6517TA (Direct Substitute):

The 2N6517TA is the primary equivalent for the 2N6517RLRA. This part maintains identical electrical specifications across all critical parameters: 350 V breakdown voltage, 500 mA collector current, 625 mW power rating, 200 MHz transition frequency, and matching DC current gain and saturation voltage characteristics. The 2N6517TA is classified as Active product status, ensuring ongoing availability and manufacturing support. The part is ROHS3 compliant, addressing regulatory requirements for new designs and procurement. The packaging is identical TO-92-3 Through Hole configuration. This substitute provides direct functional and mechanical compatibility with no circuit modifications required.

KSP42TA (Similar Substitute):

The KSP42TA is a functionally compatible alternative within the same package family but with modified electrical specifications. This part maintains 500 mA collector current and 625 mW power rating but operates at a reduced 300 V breakdown voltage (50 V lower than the main part) and 50 MHz transition frequency (150 MHz lower than the main part). The KSP42TA exhibits superior DC current gain (40 vs. 20) and lower saturation voltage (500 mV vs. 1V), characteristics that may provide performance advantages in specific circuit topologies. The KSP42TA is Active product status and ROHS3 compliant. Selection of this substitute requires circuit evaluation to confirm that the reduced voltage and frequency ratings are compatible with application requirements.

Frequently Asked Questions (FAQ)

Q: Can the 2N6517TA be used as a direct replacement for the 2N6517RLRA without circuit modifications?

A: Yes. The 2N6517TA maintains identical electrical specifications across all critical parameters including breakdown voltage, collector current, power dissipation, transition frequency, DC current gain, and saturation voltage. The packaging and pin configuration are identical. No circuit modifications are required.

Q: What are the key differences between the 2N6517TA and KSP42TA?

A: The 2N6517TA maintains the original 350 V breakdown voltage and 200 MHz transition frequency of the 2N6517RLRA. The KSP42TA operates at 300 V breakdown voltage and 50 MHz transition frequency. The KSP42TA provides higher DC current gain (40 vs. 20) and lower saturation voltage (500 mV vs. 1V). Selection between these parts depends on circuit voltage and frequency requirements.

Q: Is the KSP42TA suitable for all applications using the 2N6517RLRA?

A: The KSP42TA is suitable only for applications where the circuit voltage does not exceed 300 V and where the 50 MHz transition frequency is adequate. Applications requiring the full 350 V rating or 200 MHz frequency response must use the 2N6517TA. Circuit evaluation is required to confirm compatibility.

Q: What is the packaging difference between the 2N6517RLRA and its substitutes?

A: All three parts use identical TO-92-3 Through Hole packaging. The primary difference is in the supplier device package designation: the 2N6517RLRA uses TO-92 (TO-226), while the 2N6517TA and KSP42TA use TO-92-3 (TO-226AA). Both designations refer to the same physical package configuration with formed leads.

Q: Are there compliance or regulatory differences between these parts?

A: The 2N6517RLRA is RoHS non-compliant. Both the 2N6517TA and KSP42TA are ROHS3 compliant. For new designs or procurement subject to RoHS regulations, the 2N6517TA or KSP42TA must be selected.

Q: What is the inventory status of these parts?

A: The 2N6517RLRA has 1130 pieces in stock but is classified as obsolete. The 2N6517TA has 8200 pieces in stock and is Active. The KSP42TA has 55300 pieces in stock and is Active. For long-term procurement continuity, the 2N6517TA is the recommended choice.

Q: Can these parts be used interchangeably in existing designs?

A: The 2N6517TA can be used interchangeably with the 2N6517RLRA. The KSP42TA requires circuit evaluation due to reduced voltage and frequency ratings. Mechanical compatibility is confirmed for all three parts in TO-92-3 Through Hole applications.
