Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2N6517-AP is determined by strict equivalence across the following critical electrical and mechanical parameters:

Electrical Parameters (Must Match):

• Transistor Type: NPN
• Maximum Collector Current (Ic): 500 mA
• Collector-Emitter Breakdown Voltage: 350 V
• Maximum Power Dissipation: 625 mW
• Transition Frequency: 200 MHz
• Vce Saturation characteristics: 1 V @ 5 mA, 50 mA
• Collector Cutoff Current (ICBO): 50 nA

Mechanical Parameters (Must Match):

• Mounting Type: Through Hole
• Package / Case: TO-92-3 (TO-226AA Formed Leads)

Acceptable Variations:

• DC Current Gain (hFE) may vary within manufacturer specifications at different test conditions
• Operating temperature maximum may extend to 150°C
• Product status may differ (active vs. obsolete)
• Packaging format (Cut Tape vs. other formats) does not affect electrical compatibility

The 2N6517TA manufactured by onsemi meets all critical electrical and mechanical substitution criteria and is classified as an active product with current manufacturing support.

Parameter Comparison

Engineering Selection Recommendations

The 2N6517TA is a direct electrical and mechanical substitute for the 2N6517-AP based on equivalence of all critical parameters: collector current, breakdown voltage, power dissipation, transition frequency, saturation characteristics, and package configuration.

Product Status Consideration: The 2N6517-AP is obsolete with no active manufacturing support. The 2N6517TA is an active product with current production availability, making it the preferred selection for new designs, repairs, and ongoing production support.

Compliance Consideration: Both parts are RoHS compliant. The 2N6517TA carries ROHS3 certification, representing current regulatory compliance standards. The 2N6517TA is REACH Unaffected, confirming compliance with chemical substance regulations.

Inventory and Availability: The 2N6517TA has significantly higher inventory availability (8200 Pcs) compared to the 2N6517-AP (941 Pcs), supporting sustained supply chain requirements.

DC Current Gain Variation: The DC Current Gain (hFE) specifications differ between parts at different test conditions. The 2N6517-AP specifies 30 @ 30 mA, 10 V, while the 2N6517TA specifies 20 @ 50 mA, 10 V. Both values remain within acceptable operating ranges for general-purpose NPN transistor applications and do not restrict substitution.

Frequently Asked Questions (FAQ)

Q: Can the 2N6517TA directly replace the 2N6517-AP in existing circuits?

A: Yes. The 2N6517TA is electrically and mechanically equivalent to the 2N6517-AP. All critical parameters—collector current, breakdown voltage, power dissipation, transition frequency, and package configuration—are identical. Direct pin-for-pin substitution is supported without circuit modification.

Q: What is the significance of the different DC Current Gain (hFE) specifications?

A: The hFE specifications are measured at different test conditions. The 2N6517-AP specifies hFE at 30 mA collector current, while the 2N6517TA specifies hFE at 50 mA collector current. Both values fall within normal operating ranges for NPN transistors and do not affect substitution compatibility in general-purpose switching and amplification circuits.

Q: Why is the 2N6517TA preferred over the 2N6517-AP?

A: The 2N6517TA is an active product with current manufacturing support, while the 2N6517-AP is obsolete. The 2N6517TA offers superior availability, current regulatory compliance (ROHS3), and sustained supply chain support for both new designs and ongoing maintenance applications.

Q: Are there any package or pinout differences between these parts?

A: No. Both parts use the TO-92-3 package with TO-226AA formed leads. Pinout and mechanical dimensions are identical, supporting direct substitution without any physical modifications to circuit boards or assemblies.

Q: What is the operating temperature range for the 2N6517TA?

A: The 2N6517TA operates across a maximum junction temperature of 150°C, matching the 2N6517-AP specification. Both parts support the same thermal operating envelope.

Q: Is the 2N6517TA RoHS compliant?

A: Yes. The 2N6517TA is ROHS3 compliant and REACH Unaffected, meeting current environmental and chemical substance regulations. The 2N6517-AP is RoHS compliant, confirming both parts meet lead-free and hazardous substance restrictions.
