Engineering Selection Recommendations

BC847BM3T5G (onsemi): This substitute maintains identical package geometry (SOT-723) and electrical performance characteristics with the 2SC584600L. The BC847BM3T5G is an active product with RoHS3 compliance and REACH unaffected status. Operating temperature range extends to 150°C, providing enhanced thermal margin. The 45 V collector-emitter breakdown voltage is 5 V lower than the main part; this substitution is suitable for applications where the 50 V rating is not a critical design requirement. Current inventory of 16,800 units supports immediate availability.

2PC4617RM,315 (Nexperia USA Inc.): This substitute meets the 50 V collector-emitter breakdown voltage specification and maintains 100 mA maximum collector current. The part is packaged in SOT-883, which differs from the SOT-723 package of the main part and requires PCB layout modification. The 2PC4617RM,315 is an active product with AEC-Q100 automotive qualification, RoHS3 compliance, and REACH unaffected status. Maximum power dissipation of 430 mW exceeds the main part specification. This substitution requires footprint redesign and is suitable for applications where automotive-grade qualification is required.

Frequently Asked Questions (FAQ)

Q: Can the BC847BM3T5G directly replace the 2SC584600L without PCB modification?

A: Yes. The BC847BM3T5G uses the same SOT-723 package as the 2SC584600L, allowing direct footprint compatibility. No PCB layout changes are required for this substitution.

Q: Is the 45 V collector-emitter breakdown voltage of the BC847BM3T5G acceptable as a substitute for the 50 V rating?

A: The BC847BM3T5G has a 45 V maximum collector-emitter breakdown voltage, which is 5 V lower than the 2SC584600L specification. Substitution is acceptable only if the application design does not require the full 50 V rating and operates within the 45 V limit.

Q: What package changes are required if using the 2PC4617RM,315?

A: The 2PC4617RM,315 is packaged in SOT-883, whereas the 2SC584600L uses SOT-723. These packages have different footprints and pin configurations. PCB redesign is necessary to accommodate the SOT-883 package.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both the BC847BM3T5G and 2PC4617RM,315 are RoHS3 compliant and REACH unaffected.

Q: Which substitute part has the highest current inventory?

A: The BC847BM3T5G has 16,800 units in stock, compared to 1,017 units for the 2PC4617RM,315.

Q: Does the 2PC4617RM,315 have automotive qualification?

A: Yes. The 2PC4617RM,315 is AEC-Q100 qualified, making it suitable for automotive applications.

Q: What is the maximum operating temperature for each substitute?

A: Both substitute parts support a maximum operating temperature of 150°C, compared to 125°C for the 2SC584600L.
