Engineering Selection Recommendations

The Bourns Inc. TIP30B-S is obsolete. The onsemi TIP30CG is active and satisfies all listed compliance requirements, including ROHS3. Both devices use the TO-220-3 package, are through-hole mounted, and have an ECCN code of EAR99. Selection should consider product status and compliance with ROHS3, as provided.

Frequently Asked Questions (FAQ)

Q1: What is the primary criteria for substituting TIP30B-S?
A1: Substitute devices must match the PNP transistor type, electrical parameters (voltage, current, gain, and power), package type (TO-220-3), mounting method, and compliance status.

Q2: Is the TIP30CG functionally equivalent to the TIP30B-S?
A2: The TIP30CG matches all explicitly listed electrical and mechanical specifications required for the TIP30B-S.

Q3: Can I use the TIP30CG directly in place of TIP30B-S in existing designs?
A3: Both devices share the same mechanical footprint, electrical ratings within the allowed parameters, and mounting style, supporting direct substitution based on the provided parameters.

Q4: Are there differences in compliance or classifications between TIP30B-S and TIP30CG?
A4: Both devices are ROHS3 compliant and have the same ECCN code (EAR99), aligning with standard compliance requirements based on the input data.

Q5: Does the package type or mounting method affect compatibility?
A5: Both TIP30B-S and TIP30CG utilize the TO-220-3 package and are intended for through-hole mounting, ensuring compatibility for board-level replacement.
