Frequently Asked Questions (FAQ)

Q: Can BC856BS,135 be used as a direct replacement for BC856BS/ZLF?

A: Yes. BC856BS,135 is electrically and mechanically equivalent to BC856BS/ZLF. Both are dual PNP transistor arrays in 6-TSSOP packaging with identical voltage (65V), current (100mA), and frequency (100MHz) specifications. The primary difference is product status: BC856BS,135 is active, while BC856BS/ZLF is obsolete.

Q: What is the difference between BC856BS,135 and NSVT65010MW6T1G?

A: Both parts meet all electrical requirements for BC856BS/ZLF substitution. The key differences are: (1) Manufacturer—BC856BS,135 is Nexperia; NSVT65010MW6T1G is onsemi; (2) Power dissipation—BC856BS,135 rated at 300mW; NSVT65010MW6T1G rated at 380mW; (3) Operating temperature range—BC856BS,135 specified to 150°C; NSVT65010MW6T1G specified from -55°C to 150°C; (4) DC current gain—BC856BS,135 minimum 200 hFE; NSVT65010MW6T1G minimum 220 hFE.

Q: Are the package footprints identical between all three parts?

A: Yes. BC856BS/ZLF, BC856BS,135, and NSVT65010MW6T1G all use 6-TSSOP, SC-88, or SOT-363 package designations. These are pin-compatible surface mount packages with identical lead spacing and PCB footprints, allowing direct substitution without layout modifications.

Q: Do both substitute parts meet RoHS and REACH compliance requirements?

A: Yes. Both BC856BS,135 and NSVT65010MW6T1G are ROHS3 compliant and REACH unaffected, matching the compliance status of BC856BS/ZLF. Both parts carry MSL 1 (Unlimited) moisture sensitivity ratings.

Q: Which substitute part should be selected for automotive applications?

A: BC856BS,135 carries AEC-Q101 automotive qualification, making it the specified choice for automotive-grade designs. NSVT65010MW6T1G does not list automotive qualification in the provided specifications.
