Parametric Equivalents maintain identical electrical specifications and are sourced from the same manufacturer with different tape reel configurations.

Direct Manufacturer Substitutes are from alternative manufacturers but operate within the same voltage and current envelope with compatible packaging.

Similar Parts share the same collector voltage and current ratings but may have variations in transition frequency, power dissipation, or saturation voltage characteristics. These parts are functionally compatible for most applications but require verification of specific circuit requirements.

Engineering Selection Recommendations

Parametric Equivalent (Recommended Primary Substitute): The 2PD602AQL,215 from Nexperia USA Inc. is the direct parametric equivalent, maintaining identical electrical specifications and automotive qualification. This part is suitable for direct replacement in all applications where the 2PD602AQL,235 is specified.

Direct Manufacturer Substitute (Automotive-Qualified): The SBCX19LT1G from onsemi and BC817-40Q-13-F from Diodes Incorporated both carry AEC-Q101 automotive qualification. The SBCX19LT1G operates at 45 V collector-emitter breakdown (5 V lower than the primary part) with increased power dissipation capability (300 mW). The BC817-40Q-13-F similarly operates at 45 V with 310 mW power rating. Both are suitable for automotive applications where the reduced voltage rating is acceptable.

Similar Parts (Functional Compatibility): The 2SC3325-Y,LF from Toshiba and 2SD1484KT146Q from Rohm Semiconductor maintain the 50 V collector-emitter breakdown rating and 500 mA collector current. These parts feature higher transition frequencies (300 MHz and 250 MHz respectively) and reduced power dissipation (200 mW). Selection of these parts requires verification that the application does not depend on the 250 mW power rating of the primary part.

The BC817 series variants (BC817-16LT1G, BC817-25 RFG, BC817-40 RFG, BC817-40LT1G) operate at 45 V with 300 mW power dissipation and 100 MHz transition frequency. These parts are suitable for applications where the reduced voltage rating and lower transition frequency are compatible with circuit requirements.

Compliance Considerations: All listed parts maintain RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Parts carrying AEC-Q101 qualification are preferred for automotive applications. Non-qualified parts may be used in non-automotive applications or where design review confirms compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 2PD602AQL,215 be used as a direct replacement for the 2PD602AQL,235?

A: Yes. The 2PD602AQL,215 is a parametric equivalent with identical electrical specifications, package type, and automotive qualification. The difference in part number reflects only the tape reel configuration from the same manufacturer.

Q: What is the primary difference between the 2PD602AQL,235 and the SBCX19LT1G?

A: The SBCX19LT1G operates at a maximum collector-emitter breakdown voltage of 45 V compared to 50 V for the 2PD602AQL,235. The SBCX19LT1G provides higher power dissipation (300 mW versus 250 mW). Both parts are AEC-Q101 qualified and suitable for automotive applications where the 5 V voltage margin reduction is acceptable.

Q: Are the BC817 series parts suitable replacements for the 2PD602AQL,235?

A: The BC817 series parts (BC817-16LT1G, BC817-40LT1G, and BC817-40Q-13-F) operate at 45 V collector-emitter breakdown with 100 MHz transition frequency. These parts are functionally compatible for switching applications but operate at reduced voltage and frequency ratings. The BC817-40Q-13-F carries AEC-Q101 qualification for automotive use.

Q: What packaging options are available among the substitute parts?

A: The primary part and parametric equivalent use TO-236AB packaging. Direct and similar substitutes are available in SOT-23-3 (TO-236), S-Mini, and SMT3 packages. All packages are surface mount configurations compatible with standard PCB assembly processes. Verify PCB footprint compatibility before selection.

Q: Can I use the 2SC3325-Y,LF or 2SD1484KT146Q in place of the 2PD602AQL,235?

A: These parts maintain the 50 V collector-emitter breakdown and 500 mA collector current ratings. However, they feature reduced power dissipation (200 mW versus 250 mW) and higher transition frequencies (300 MHz and 250 MHz respectively). Selection requires verification that the application does not require the full 250 mW power budget and that the higher frequency characteristics do not introduce instability.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts maintain RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1), consistent with the primary part specification.

Q: Which substitute parts carry automotive qualification?

A: The 2PD602AQL,215, SBCX19LT1G, and BC817-40Q-13-F all carry AEC-Q101 automotive qualification. These parts are preferred for automotive applications. Non-qualified parts may be used in non-automotive applications or where design review confirms compatibility with application requirements.
