Substitute Part Grouping Explanation

Substitution of the B3L30LP-7-2477 with the B3L30LP-7 is based on electrical and mechanical parameter equivalence. Both parts share identical specifications across all critical parameters: 30 V maximum reverse voltage, 3 A average rectified current, 450 mV forward voltage drop at 3 A, fast recovery speed characteristics, and identical reverse leakage current. The mechanical compatibility is confirmed through identical package designation (8-PowerUDFN) and supplier device package (U-DFN3030-8), ensuring direct PCB footprint compatibility without layout modifications.

The substitution is further supported by compliance equivalence, with both parts meeting ROHS3 and REACH requirements. The primary distinction between these parts is product status: B3L30LP-7-2477 is obsolete, while B3L30LP-7 maintains active status with significantly higher inventory availability (2224 pieces versus 1025 pieces).

Engineering Selection Recommendations

The B3L30LP-7 is the direct substitute for the B3L30LP-7-2477. Selection of the B3L30LP-7 is based on the following engineering criteria:

Electrical equivalence is complete across all specified parameters, including reverse voltage rating, forward current capacity, forward voltage drop, switching speed, and reverse leakage characteristics. No circuit performance degradation results from this substitution.

Mechanical compatibility is confirmed through identical package specifications. Both parts utilize the 8-PowerUDFN package with U-DFN3030-8 supplier designation, ensuring direct PCB footprint compatibility without design modifications.

Compliance status is equivalent for both parts. Both achieve ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for the same application environments.

Product status differentiation favors the B3L30LP-7. The active status of B3L30LP-7 ensures long-term supply availability and manufacturing continuity, whereas the obsolete status of B3L30LP-7-2477 presents supply risk and potential discontinuation of manufacturing support.

Frequently Asked Questions (FAQ)

Q: Can B3L30LP-7 be used as a direct replacement for B3L30LP-7-2477 in existing designs?

A: Yes. The B3L30LP-7 is a direct substitute with identical electrical specifications, forward voltage characteristics, reverse voltage rating, current capacity, and switching speed. The package designation and PCB footprint are identical, requiring no design modifications.

Q: Are there any differences in the operating temperature range between these parts?

A: No. Both parts operate across the identical junction temperature range of -65°C to 150°C. Thermal performance characteristics are equivalent.

Q: What is the difference between the packaging designations listed for these parts?

A: The B3L30LP-7-2477 is supplied in standard packaging, while the B3L30LP-7 is supplied in Tape & Reel (TR) format. Both use the identical U-DFN3030-8 package geometry and PCB footprint. The difference is in the delivery format for manufacturing assembly processes.
