Frequently Asked Questions (FAQ)

Q: Can the TPH7R204PL,LQ be used as a direct replacement for the TPCA8047-H(T2L1,VM) without circuit modifications?

A: Yes. The TPH7R204PL,LQ is electrically and mechanically compatible with the TPCA8047-H(T2L1,VM). Both devices share identical voltage ratings (40V Vdss), gate voltage specifications (±20V), and package form factor (8-PowerVDFN). The higher current rating (48A vs. 32A) and improved thermal performance of the substitute part do not require circuit modifications.

Q: What are the key differences between these two MOSFETs?

A: The primary differences are: (1) Product status—TPH7R204PL,LQ is active while TPCA8047-H(T2L1,VM) is obsolete; (2) Continuous drain current—TPH7R204PL,LQ provides 48A versus 32A; (3) Maximum junction temperature—TPH7R204PL,LQ operates to 175°C versus 150°C; (4) Gate charge—TPH7R204PL,LQ has lower gate charge (24 nC vs. 43 nC), resulting in faster switching; (5) RoHS compliance—TPH7R204PL,LQ is ROHS3 compliant. All other electrical parameters remain compatible.

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

A: No. Both the TPCA8047-H(T2L1,VM) and TPH7R204PL,LQ use the 8-PowerVDFN (8-SOP Advance 5x5) surface mount package with identical pinout. No PCB layout modifications are required for substitution.

Q: What is the moisture sensitivity level for both parts?

A: Both parts carry an MSL 1 (Unlimited) rating, indicating unlimited shelf life under controlled storage conditions. Handling and storage requirements are identical between the two devices.

Q: Why does the TPH7R204PL,LQ have lower gate charge than the TPCA8047-H(T2L1,VM)?

A: Gate charge is a function of device design and die geometry. The TPH7R204PL,LQ exhibits lower gate charge (24 nC vs. 43 nC at 10V Vgs), which results in faster switching transitions and reduced gate drive power requirements. This is a beneficial characteristic that does not affect compatibility with existing gate drive circuits.

Q: Is the TPH7R204PL,LQ available in the same packaging format (Tape & Reel)?

A: The TPH7R204PL,LQ is supplied in Tape & Reel (TR) packaging. Confirm packaging format requirements with your procurement specification, as the original TPCA8047-H(T2L1,VM) packaging format was not specified in the available data.

Q: What is the significance of RoHS3 compliance on the TPH7R204PL,LQ?

A: RoHS3 compliance indicates the TPH7R204PL,LQ meets current environmental and regulatory requirements for electronic components, including restrictions on hazardous substances. This certification is required for many applications and markets. The original TPCA8047-H(T2L1,VM) compliance status was not specified.
